This document describes additional steps I follow when configuring Majordomo on FreeBSD, after installing it from the "ports" collection.
To install from ports, enter the following command sequence as root:cd /usr/ports/mail/majordomo; make; make install
The "Post-Install Notes for Majordomo" say to add a second aliases file named /usr/local/majordomo/aliases.majordomo to your sendmail.cf file. This has two problems:
Move the /usr/local/majordomo/aliases.majordomo file to the /etc/mail directory. Better still, eliminate the file altogether and put the mailing list aliases in /etc/mail/aliases.
If you decide to use a separate aliases.majordomo file, add the following line to your sendmail mc file:
define(`ALIAS_FILE',`/etc/mail/aliases,/etc/mail/aliases.majordomo')and regenerate your sendmail.cf file.
According to a footnote on page 978 of the 3rd edition of the "Bat" book, "When an argument to an m4 define command contains one or more commas, that argument should be enclosed in double half-quotes." Following those instructions, the correct syntax would probably be:define(`ALIAS_FILE',``/etc/mail/aliases,/etc/mail/aliases.majordomo'')However, single half-quotes seem to work just fine.
The aliases.majordomo file distributed with Majordomo includes the following two aliases:
majordomo-owner: Postmaster owner-test-l: Postmaster
Incoming mail to the test-l mailing list will arrive at the server successfully, but will likely fail when sendmail tries to deliver it to the list subscribers. In the /var/log/maillog, you will see a series of entries, beginning with one similar to this:
Oct 23 21:01:20 technoids.org sm-mta: h9NL1K9M013890: h9NL1K9M013891: clone: owner=Postmasterand followed by entries warning about things like ".forward: transient error", "seteuid(1001) failure (real=0, eff=0): Too many users", etc. The mail will be queued indefinitely.
Change the right-hand-side (RHS) of aliases that refer to Postmaster; change it to some non-root-equivalent user or e-mail address.
The default test list files installed in /usr/local/majordomo/lists look something like:
-rw-rw-r-- 1 majordom majordom 59 Oct 23 21:22 test-l -rw-rw-r-- 1 majordom majordom 0 Oct 23 20:41 test-l-digest drwxr-xr-x 2 majordom majordom 512 Oct 23 20:41 test-l-digest.archive -rw-rw---- 1 majordom majordom 16561 Oct 23 21:01 test-l-digest.config drwxr-xr-x 2 majordom majordom 512 Oct 23 21:27 test-l.archive -rw-rw---- 1 majordom majordom 16497 Oct 23 21:01 test-l.config -rw-rw-r-- 1 majordom majordom 124 Oct 23 20:41 test-l.info -rw-rw---- 1 majordom majordom 5 Oct 23 20:41 test-l.passwd
(Note that all non-directories are group writeable.) Sendmail will refuse to deliver to the files, instead sending a message to owner-test-l with a complaint: "Cannot open /usr/local/majordomo/lists/test-l: Group writable file"
The preferred solution is to remove group writability by issuing the following commands as root:
# cd /usr/local/majordomo/lists # chmod g-w *
Now if you issue the ls -l command, you will see:
-rw-r--r-- 1 majordom majordom 59 Oct 23 21:22 test-l -rw-r--r-- 1 majordom majordom 0 Oct 23 20:41 test-l-digest drwxr-xr-x 2 majordom majordom 512 Oct 23 20:41 test-l-digest.archive -rw-r----- 1 majordom majordom 16561 Oct 23 21:01 test-l-digest.config drwxr-xr-x 2 majordom majordom 512 Oct 23 21:27 test-l.archive -rw-r----- 1 majordom majordom 16497 Oct 23 21:01 test-l.config -rw-r--r-- 1 majordom majordom 124 Oct 23 20:41 test-l.info -rw-r----- 1 majordom majordom 5 Oct 23 20:41 test-l.passwd
An alternate solution (not recommended) is to add the following line to your sendmail mc file and generate a new sendmail.cf:
