63 This is the Administrator's Guide to \fIMH\fR. | |
64 If you don't maintain an \fIMH\fR system, | |
65 don't read this; | |
66 the information is entirely too technical. | |
67 If you are a maintainer, | |
68 then read this guide until you understand it, | |
69 follow the advice it gives, | |
70 and then forget about the guide. | |
71 .pp | |
72 Before continuing, I'll point out two facts: | |
73 .sp 2 | |
74 .(l C | |
75 \fIThis document will never contain all the information | |
76 you need to maintain MH. | |
77 .sp | |
78 Furthermore, this document will never contain everything | |
79 I know about maintaining MH.\fR | |
80 .)l | |
81 .sp 2 | |
82 \fIMH\fR, | |
83 and mailsystems in general, | |
84 are more complex than most people realize. | |
85 A combination of experience, intuition, and tenacity is required to maintain | |
86 \fIMH\fR properly. | |
87 This document can provide only guidelines for bringing up an \fIMH\fR system | |
88 and maintaining it. | |
89 There is a sufficient amount of customization possible that not all events or | |
90 problems can be forseen. | |
91 | |
92 .uh "Summary" | |
93 .pp | |
94 During \fIMH\fR generation, | |
95 you specify several configuration constants to the \fImhconfig\fR program. | |
96 These directives take into consideration such issues as hardware and | |
97 operating system dependencies in the source code. | |
98 They also factor out some major mailsystem administrative decisions | |
99 that are likely to be made consistantly at sites with more than one host. | |
100 The manual entry \fImh\-gen\fR\0(8) describes all the static configuration | |
101 directives. | |
102 .pp | |
103 However, | |
104 when you install \fIMH\fR you may wish to make some site\-specific | |
105 or host\-specific changes which aren't hardware or even software related. | |
106 Rather, they are administrative decisions. | |
107 That's what this guide is for: it describes all of the dynamically tailorable | |
108 directives. | |
109 .pp | |
110 Usually, after installing \fIMH\fR, you'll want to edit the | |
111 \fB/usr/local/mh/lib/mtstailor\fR file. | |
112 This file fine-tunes the way \fIMH\fR interacts with the message transport | |
113 system (MTS). | |
114 Section 2 talks about the MTS interface and MTS tailoring. | |
115 .pp | |
116 After that, if you're running the UCI BBoards facility, | |
117 or the POP facility, | |
118 you'll need to know how to maintain those systems. | |
119 Sections 3 and 4 talk about these. | |
120 .pp | |
121 If for some reason | |
122 you're not running an MTS that can handle both Internet and \fIUUCP\fR traffic, | |
123 you should read\-up on mail filtering in Section 5. | |
124 Although this is considered \*(lqold technology\*(rq now, | |
125 the mechanisms described in Section 5 were really quite useful when | |
126 first introduced way back in 1981. | |
127 .pp | |
128 Finally, you may want to know how to modify the \fIMH\fR source tree. | |
129 Section 6 talks (a little bit) about that. | |
130 .pp | |
131 The last two sections describe a few hidden features in \fIMH\fR, | |
132 and the configuration options that were in effect when this guide was | |
133 generated. | |
134 .pp | |
135 After \fIMH\fR is installed, you should define the address \*(lqBug\-MH\*(rq | |
136 to map to either you or the \fIPostMaster\fR at your site. | |
137 .pp | |
138 In addition, | |
139 if you want to tailor the behavior of \fIMH\fR for new users, | |
140 you can create and edit the file \fB/usr/local/mh/lib/mh.profile\fR. | |
141 When the \fIinstall-mh\fR program is run for a user, | |
142 if this file exists, it will copy it into the user's \&.mh\(ruprofile | |
143 file. | |

250 .+c "THE MTS INTERFACE" | |
251 .pp | |
252 The file \fB/usr/local/mh/lib/mtstailor\fR customizes | |
253 certain host\-specific parameters of \fIMH\fR | |
254 related primarily to interactions with the transport system. | |
255 The parameters in this file override the compiled\-in defaults given during | |
256 \fIMH\fR configuration. | |
257 Rather than recompiling \fIMH\fR on each host to make minor customizations, | |
258 it is easier simply to modify the \fBmtstailor\fR file. | |
259 All hosts at a given site normally use the same \fBmtstailor\fR file, | |
260 though this need not be the case. | |
261 .pp | |
262 It is a good idea to run the \fIconflict\fR\0(8) program each morning | |
263 under \fIcron\fR. | |
264 The following line usually suffices: | |

286 .+c "BBOARDS" | |
287 .pp | |
288 The UCI BBoards facility has two aspects: message reading, and | |
289 message delivery. The configuration directives applicable to | |
290 BBoards are \*(lqbboards: on/off/pop/nntp\*(rq and | |
291 \*(lqbbdelivery: on/off\*(rq. | |
292 .uh "BBoard Delivery" | |
293 .pp | |
294 If you enabled BBoards delivery (\*(lqbbdelivery: on\*(rq) | |
295 during configuration, | |
296 then the initial environment for bboards delivery | |
297 was set\-up during installation. | |
298 A BBoard called \*(lqsystem\*(rq is established, | |
299 which is the BBoard for general discussion. | |
300 .pp | |
301 To add more BBoards, become the \*(lqbboards\*(rq user, | |
302 and edit the \fB/BBoards\fR file. | |
303 The file \fBsupport/bboards/Example\fR is a copy of the | |
304 \fB/BBoards\fR file that we use at UCI. | |
305 When you add a BBoard, | |
306 you don't have to create the files associated with it, | |
307 the BBoards delivery system will do that automatically. | |
308 .pp | |
309 Private BBoards may be created. | |
310 To add the fictitious private BBoard \*(lqhacks\*(rq, | |
311 add the appropriate entry to the BBoards file, | |
312 create the empty file \fB/hacks.mbox\fR (or whatever), | |
313 change the mode of this file to 0640, | |
314 and change the group of the file to be the groupid of the people that you | |
315 want to be able to read it. | |
316 Also be sure to add the \*(lqbboards\*(rq user to this group | |
317 (in \fB/etc/group\fR), | |
318 so the archives can be owned correctly. | |
319 .pp | |
320 By using the special INVIS flag for a BBoard, | |
321 special purpose BBoards may be set\-up which are invisible to the \fIMH\fR | |
322 user. | |
323 For example, | |
324 if a site distributes a BBoard both locally to a number of machines and to a | |
325 number of distant machines. | |
326 It might be useful to have two distribution lists: | |
327 one for all machines on the list, and the other for local machines only. | |
328 This is actually very simple to do. | |
329 For the main list, | |
330 put the standard entry of information in the \fB/BBoards\fR file, | |
331 with the complete distribution list. | |
332 For the local machines list, | |
333 and add a similar entry to the \fB/BBoards\fR file. | |
334 All the fields should be the same except three: | |
335 the BBoard name should reflect a local designation (e.g., \*(lql\-hacks\*(rq), | |
336 the distribution list should contain only machines at the local site, | |
337 and the flags field should contain the INVIS flag. | |
338 Since the two entries share the same primary and archive files, | |
339 messages sent to either list are read by local users, | |
340 while only thoses messages sent to the main list are read by all users. | |
341 .pp | |
342 Two automatic facilities for dealing with BBoards exist: | |
343 automatic archiving and automatic aliasing. | |
344 The file \fBsupport/bboards/crontab\fR contains some entries that you | |
345 should add to your \fB/usr/lib/crontab\fR file to run the specified programs | |
346 at times that are convenient for you. | |
347 The \fBbboards.daily\fR file is run once a day and generates an alias file | |
348 for \fIMH\fR. | |
349 By using this file, users of \fIMH\fR can use, for example, | |
350 \*(lqunix\-wizards\*(rq instead of \*(lqunix\-wizards@brl\-vgr\*(rq | |
351 when they want to send a message to the \*(lqunix\-wizards\*(rq | |
352 discussion group. | |
353 This is a major win, since you just have to know the name of the group, | |
354 not the address where it's located. | |
355 .pp | |
356 The \fBbboards.weekly\fR file is run once a week and handles old | |
357 messages (those received more than 12 days ago) in the BBoards area. | |
358 In short, | |
359 those BBoards which are marked for automatic archiving | |
360 will have their old messages placed in the \fB/archive/\fR area, | |
361 or have their old messages removed. | |
362 Not only does this make BBoards faster to read, | |
363 but it conveniently partitions the new messages from the old messages | |
364 so you can easily put the old messages on tape and then remove them. | |
365 It turns out that this automatic archiving capability is also a major | |
366 win. | |
367 .pp | |
368 At UCI, | |
369 our policy is to save archived messages on tape (every two months or so). | |
370 We use a program called \fIbbtar\fR to implement our particular policy. | |
371 Since some BBoards are private (see above), | |
372 we save the archives on two tapes: | |
373 one containing the world\-readable archives | |
374 (this tape is read-only accessible to all users by calling the operator), | |
375 and the other containing the non\-world\-readable ones | |
376 (this tape is kept locked\-up somewhere). | |
377 .uh "BBoards with the POP" | |
378 .pp | |
379 If you configured \fIMH\fP with \*(lqbboards: pop\*(rq and \*(lqpop: on\*(rq, | |
380 then the \fIMH\fR user is allowed to read BBoards on a server machine | |
381 instead of the local host (thus saving disk space). | |
382 For completely transparent behavior, | |
383 the administrator may set certain variables in the \fBmtstailor\fR file | |
384 on the client host. | |
385 The variable \*(lqpopbbhost\*(rq indicates the host where BBoards are | |
386 kept | |
387 (it doesn't have to be the POP service host, | |
388 but this host must run both a POP server and the BBoards system). | |
389 The variable \*(lqpopbbuser\*(rq indicates the guest account on this host | |
390 for BBoards. | |
391 This username should not be either the POP user or the BBoards user. | |
392 Usually the anonymous FTP user (ftp) is the best choice. | |
393 Finally, the variable \*(lqpopbblist\*(rq indicates the name of a file which | |
394 contains a list of hosts (one to a line, official host names only) which | |
395 should be allowed to use the POP facility to access BBoards via the guest | |
396 account. | |
397 (If the file is not present, then no check is made.) | |
398 .pp | |
399 The \*(lqpopbbuser\*(rq variable should be set on both the client and service | |
400 host. | |
401 The \*(lqpopbbhost\*(rq variable need be set only on the client host | |
402 (the value, of course, is the name of the service host). | |
403 The \*(lqpopbblist\*(rq variable need be set only on the service host. | |
404 .pp | |
405 Finally, | |
406 on the client host, | |
407 if a POP service host is not explicitly given by the user | |
408 (i.e., \*(lqpopbbhost\*(rq is implicitly used), | |
409 then \fIbbc\fR will explicitly check the local host prior to contacting | |
410 the service host. | |
411 This allows each POP client host to have a few local BBoards | |
412 (e.g., each host could have one called \*(lqsystem\*(rq), | |
413 and then have the POP service host used for all the rest | |
414 (a site\-wide BBoard might be known as \*(lqgeneral\*(rq). | |
415 .uh "BBoards with the NNTP" | |
416 .pp | |
417 If you configured \fIMH\fP with \*(lqbboards: nntp\*(rq and \*(lqpop: on\*(rq, | |
418 then | |
419 the \fIMH\fR user is allowed to read the Network News on a | |
420 server machine using the standard \fIbbc\fR command. | |
421 For completely transparent behavior, | |
422 the administrator may set the \*(lqnntphost\*(rq variable in the | |
423 \fBmtstailor\fR file to indicate the host where the Network News is kept. | |
424 The \*(lqnntphost\*(rq variable should be set only on the client host | |
425 Finally, | |
426 on the client host, | |
427 if an NNTP service host is not explicitly given by the user | |
428 (i.e., \*(lqnntphost\*(rq is implicitly used), | |
429 then \fIbbc\fR will explicitly check the local host prior to contacting | |
430 the service host. | |
431 This allows each NNTP client host to have a few local BBoards | |
432 (e.g., each host could have one called \*(lqsystem\*(rq), | |
433 and then have the NNTP service host used for to read the Network News. | |
434 .pp | |
435 Reading BBoards via the POP and via the NNTP are mutually exclusive. | |

456 .+c "POP" | |
457 .pp | |
458 For POP (Post Office Protocol) client hosts, | |
459 you need to edit the \fB/usr/local/mh/lib/mtstailor\fR file to know about two | |
460 hosts: | |
461 the SMTP service host and the POP service host. | |
462 Normally, these are the same. | |
463 Change the \*(lqlocalname\*(rq field of the \fBmtstailor\fR file | |
464 of \fIMH\fR in the file to be the name of the POP service host. | |
465 This makes replies to mail generated on the POP client host possible, | |
466 since \fIMH\fR will consider use the hostname of the POP service host as the | |
467 local hostname for outgoing mail. | |
468 Also set the value of \*(lqpophost\*(rq to this value. | |
469 This tells \fIinc\fR and \fImsgchk\fR to use POP instead of looking for mail | |
470 locally. | |
471 Finally, | |
472 make sure the value of \*(lqservers\*(rq includes the name of the SMTP | |
473 service host. | |
474 The recommended value for \*(lqservers\*(rq is: | |
475 | |
476 .ti +.5i | |
477 servers:\ SMTP\-service\-host localhost \\01localnet | |
478 .pp | |
479 If you want more information on the Post Office Protocol used by \fIMH\fR, | |
480 consult the files \fBsupport/pop/rfc1081.txt\fP and | |
481 \fBsupport/pop/rfc1082.txt\fP which describe the \fIMH\fP version of | |
482 the POP: POP3. | |
483 .pp | |
484 For POP service hosts, | |
485 you need to run a daemon, \fIpopd\fR\0(8). | |
486 The daemon should start at multi\-user boot time, | |
487 so adding the lines: | |
488 .sp | |
489 .nf | |

499 The port assigned to the POP3 protocol is \*(lq110\*(rq. | |
500 For historical reasons, many sites are using port \*(lq109\*(rq | |
501 which is the port assigned to the \*(lqPOP\*(rq (version 1 and 2) protocol. | |
502 The configuration option \*(lqPOPSERVICE\*(rq is the name of the | |
503 port number that \fIMH\fP POP will try to use, and defaults to the | |
504 name \*(lqpop\*(rq. | |
505 .pp | |
506 To generate \fIMH\fP to use newer assigned port number, | |
507 in your \fIMH\fP config file, add: | |
508 .sp | |
509 .ti +.5i | |
510 options POPSERVICE='\*(lqpop3\*(rq' | |
511 .sp | |
512 And on both the POP client and service hosts, | |
513 you need to define the port that the POP service uses. | |
514 Add the line: | |
515 .sp | |
516 .nf | |
517 .in +.5i | |
518 pop3 110/tcp | |
519 .in -.5i | |

521 .sp | |
522 to the \fB/etc/services\fR file (if it's not already there). | |
523 .pp | |
524 There are two ways to administer POP: | |
525 In \*(lqnaive\*(rq mode, | |
526 each user-id in the \fIpasswd\fR\0(5) file is considered a POP subscriber. | |
527 No changes are required for the mailsystem on the POP service host. | |
528 However, | |
529 this method requires that each POP subscriber have an entry in the password | |
530 file. | |
531 The POP server will fetch the user's mail from wherever maildrops are kept on | |
532 the POP service host. | |
533 This means that if maildrops are kept in the user's home directory, | |
534 then each POP subscriber must have a home directory. | |
535 .pp | |
536 In \*(lqsmart\*(rq mode | |
537 (enabled via \*(lqDPOP\*(rq being given as a configuration option), | |
538 the list of POP subscribers and the list of | |
539 login users are completely separate name spaces. | |
540 A separate database (simple file similar to the \fIBBoards\fR\0(5) file) | |
541 is used to record information about each POP subscriber. | |
542 Unfortunately, | |
543 the local mailsystem must be changed to reflect this. | |
544 This requires two changes (both of which are simple): | |
545 First, | |
546 the aliasing mechanism is augmented so that POP subscriber addresses | |
547 are diverted to a special delivery mechanism. | |
548 \fIMH\fR comes with a program, \fIpopaka\fR\0(8), | |
549 which generates the additional information to be put in the mailsystem's | |
550 alias file. | |
551 Second, | |
552 a special POP channel (for MMDF-II) or POP mailer (for SendMail) | |
553 performs the actual delivery (\fImh.6\fR supplies both). | |
554 All it really does is just place the mail in the POP spool area. | |
555 .pp | |
556 These two different philosophies are not compatible on the same POP service | |
557 host: one or the other, but not both may be run. | |
558 Clever mailsystem people will note that | |
559 the POP mechanism is really a special case of the more general | |
560 BBoards mechanism. | |
561 .pp | |
562 In addition, there is one user-visible difference, | |
563 which the administrator controls the availability of. | |
564 The difference is whether the POP subscriber must supply a password to the POP | |
565 server: | |
566 The first method uses the standard ARPA technique of sending a username and a | |
567 password. | |
568 The appropriate programs (\fIinc\fR, \fImsgchk\fR, and possibly \fIbbc\fR\0) | |
569 will prompt the user for this information. | |
570 .pp | |
571 The second method | |
572 (which is enabled via \*(lqRPOP\*(rq being given as a configuration option) | |
573 uses the Berkeley UNIX reserved port method for authentication. | |
574 This requires that the two or three mentioned above programs be | |
575 \fIsetuid\fR to root. | |
576 (There are no known holes in any of these programs.) | |
577 .pp | |
578 To add a POP subscriber, | |
579 for the first method, one simply follows the usual procedures for adding a | |
580 new user, which eventually results in adding a line to the \fIpasswd\fR\0(5) | |
581 file; | |
582 for the second method, one must edit the POP database file | |
583 (kept in the home directory of the POP user), | |
584 and then run the \fIpopaka\fR program. | |
585 The output of this program is placed in the aliases file for the transport | |
586 system (e.g., \fB/usr/lib/aliases\fR for SendMail). | |
587 .pp | |
588 Authentication for POP subscribers differs | |
589 depending on the two methods. | |
590 When the user supplies a password for the POP session: | |
591 under the first method, | |
592 the contents of the password field for the user's entry in the | |
593 \fIpasswd\fR\0(5) is consulted; | |
594 under the second method, | |
595 the contents of the password field for the subscriber's entry in the | |
596 \fIpop\fR\0(5) file is consulted. | |
597 (To set this field, the \fIpopwrd\fR\0(8) program is used.) | |
598 .pp | |
599 If you are allowing RPOP, | |
600 under the first method, | |
601 the user's \fI\&.rhosts\fR file is consulted; | |
602 under the second method, | |
603 the contents of the network address field for the subscriber's entry | |
604 in the \fIpop\fR\0(5) file is consulted. | |
605 .pp | |
606 In addition, | |
607 a third authentication scheme is available. | |
608 When the APOP configuration option is given, | |
609 e.g., | |
610 .sp | |
611 .ti +.5i | |
612 options APOP='\*(lq/etc/pop.auth\*(rq' | |
613 .sp | |
614 In this case, | |
615 the server also allows a client to supply authentication | |
616 credentials to provide for origin authentication and reply protection, | |
617 but which do not involve sending a password in the clear over the network. | |
618 A POP authorization DB, | |
619 having as its name the value of APOP configuration option, | |
620 is used to keep track of this information. | |
621 This file is created and manipulated by the \fIpopauth\fR\0(8) program. | |
622 Because this file contains secret information, | |
623 it must be protected mode 0600 and owned by the super-user. | |
624 Hence, | |
625 your first step after installing the software is to issue | |
626 .sp | |
627 .ti +.5i | |
628 # popauth -init | |
629 .sp | |
630 which creates and initalizes the POP authorization DB. | |

652 .+c "MAIL FILTERING" | |
653 .pp | |
654 There was a time when users on a UNIX host might have had two maildrops: | |
655 one from \fIMMDF\fR and the other from \fIUUCP\fR. | |
656 This was really a bad problem since it prevented using a single | |
657 user\-interface on all of your mail. | |
658 Furthermore, | |
659 if you wanted to send a message to addresses on different mailsystems, | |
660 you couldn't send just one message. | |
661 To solve all these problems, | |
662 the notion of \fImail filtering\fR was developed that allowed sophisticated | |
663 munging and relaying between the two pseudo\-domains. | |
664 .pp | |
665 \fIMH\fR will perform mail filtering, transparently, if given the MF | |
666 configuration option. | |
667 However, | |
668 with the advent of \fISendMail\fR and further maturation of \fIMMDF\fR, | |
669 \fIMH\fR doesn't really need to do this anymore, | |
670 since these message transport agents handle it. | |
671 .pp | |
672 The mail\-filtering stuff is too complicated. | |
673 It should be simpler, but, protocol translation really \fIis\fR difficult. | |

754 The capabilities discussed here should not be used on a production basis, | |
755 as they are either experimental, are useful for debugging \fIMH\fR, or | |
756 are otherwise not recommended. | |
757 | |
758 .uh "Debug Facilities" | |
759 .pp | |
760 The \fImark\fR command has a `\-debug' switch which essentially prints out | |
761 all the internal \fIMH\fR data structures for the folder you're looking at. | |
762 .pp | |
763 The \fIpost\fR command has a `\-debug' switch which does everything but | |
764 actually post the message for you. | |
765 Instead of posting the draft, it sends it to the standard output. | |
766 Similarly, | |
767 \fIsend\fR has a `\-debug' switch which gets passed to \fIpost\fR. | |
768 .pp | |
769 Some \fIMH\fR commands look at envariables to determine debug\-mode operation | |
770 of certain new facilities. | |
771 The current list of envariables is: | |

787 .pp | |
788 The \fIforw\fR and \fImhl\fR commands have two switches, | |
789 `\-dashmunging' and `\-nodashmunging' which enable or disable | |
790 the prepending of `\-\ ' in forwarded messages. To use | |
791 `\-nodashmunging', you must use an \fImhl\fR filter file. | |
792 | |
793 .uh "Send" | |
794 .pp | |
795 The \fIsend\fR command has two switches, `\-unique' and `\-nounique', | |
796 which are useful to certain individuals who, for obscure reasons, | |
797 do not use draft\-folders. | |
798 .pp | |
799 \*(lqDistribution Carbon Copy\*(rq addresses may be specified in | |
800 the \fIDcc:\fR header. | |
801 This header is removed before posting the message,and a copy of the message | |
802 is distributed to each listed address. | |
803 This could be considered a form of Blind | |
804 Carbon Copy which is best used for sending to an address which | |
805 would never reply (such as an auto\-archiver). | |
806 | |
807 .uh "Posting Mail" | |
808 .pp | |
809 If you're running a version of \fIMH\fR which talks directly to an | |
810 \fISMTP\fR server (or perhaps an advanced \fIMMDF\fR submit process), | |
811 there are lots of interesting switches for your amusement which \fIsend\fR | |
812 and \fIpost\fR understand: | |
813 .nf | |
814 .in +.5i | |
815 .ta \w'-server host 'u | |
816 ^-mail~^Use the \fIMAIL\fR command (default) | |
817 ^-saml~^Use the \fISAML\fR command | |
818 ^-send~^Use the \fISEND\fR command | |
819 ^-soml~^Use the \fISOML\fR command | |
820 ^-snoop~^Watch the \fISMTP\fR transaction | |
821 ^-client host~^Claim to be \*(lqhost\*(rq when posting mail | |
822 ^-server host~^Post mail with \*(lqhost\*(rq | |
823 .re | |
824 .in -.5i | |
825 .fi | |
826 .pp | |
827 The last switch is to be useful when \fIMH\fR resides on small | |
828 workstations (or PC:s) in a network\-\-they can post their outgoing mail with | |
829 a local relay, | |
830 and reduce the load on the local system. | |
831 On POP client hosts, | |
832 the `\-server\ host' switch is defaulted appropriately using the SMTP | |
833 search\-list mechanism. | |
834 The \fIwhom\fR command understands the last three switches. | |
