Sendmail and passwd-like file.
Zuzanna K. Filutowska
Is there any way to make sendmail to use a passwd-like password file to
look up the usernames instead of using getpwnam?
Regards.

doc/op/op.*:
MailboxDatabase
[no short name] Type of lookup to find
information about local mailboxes, defaults
to ``pw'' which uses getpwnam. Other types
can be introduced by adding them to the
source code, see libsm/mbdb.c for details.

Well, I have already read this one, as well as that source file, but the
problem is I am not a programmer, and I am unable to hack sendmail's
source code at all, especially that it using getpwnam function to access
the passwd files, which would require me to write own function or modify
getpwnam, so it is easy to say "modify the source code to add new
functionality".

Have you considered using custom (perl?) script to convent plain text
/etc/passwd-dovecot to
* virtusertable entries
*OR*
* custom map listing "domain-less users" user for LUSER_RELAY
http://groups.google.com/group/comp.mail.sendmail/msg/c6ce04d354feedad
You can create simple makefile and choose one of the following
* run it every 10m from cron
* run it manually after changing /etc/passwd-dovecot
* write simple (perl?) daemon to monitor the file every minute and
execute makefile when needed
P.S.
Remember that SMTP-AUTH integration is a separate story.

Would you state it is one of the best opportunities?
I have attempted a few time (2+) to "*fully* understand/read" sendmail
code. Every time I came to conclusion it would not be "cost effective".
I would not dare to state that sendmail code has been written in open
development requirements in mind.

Thanks for the tip about my professional career. Not to be rude, but maybe
I should drop my job and start learning how to produce cars, build houses,
perform brain surgery etc. just because it is useful? I could even
try...but, since I have to drop my job, untill I would finish my education
I will die from starvation.

Yep. I remember this. And it makes me sad, that almost everything
(including ftp and imap daemon) supports alternate passwd but not
sendmail.

Are interested in *testing* new (via sendmail.cf *only*) sendmail and
"dovecot with passwd file" integration?
a) sendmail will check /etc/passwd-dovecot *directly*
b) sendmail will support "domanized aliases" in domains handled by
dovecot
It will require:
1) applying 6 lines patch to cf/m4/proto.m4
2) adding one new file to cf/feature/ directory
It will be a variation of FEATURE(`anfi/vcyrus') available at
http://open-sendmail.sourceforge.net/

I may be wrong, but I _believe_ to remember that sasl2 supports
saslauthd as an authentication daemon and this one can be configured to
use PAM. Now with PAM you can go lengths.

This is Slackware, and Slackware is a synonym for "PAM-hell-no" (which I
happen to agree with).
Regarding to suggestions to use LDAP, well I know I may use LDAP, and I
have even configured LDAP or SQL with Sendmail, but the whole issue is
that I don't like these (I am migrating a site from exim+SQL now).
However, I have found a willing programmer to help, I have explained him
how does Sendmail's mbdb works and we have worked out a solution:

I would gladly test it.

I don't like flaming, especially flames Sendmail vs. Rest Of The
World...but when I hear/read compilation of "Qmail" and
"main/large/corporate servers" it gives me shudders. I am running a site
that server 250-500k emails a day, and I can't imagine any Qmail
"backend".
Anyway, I have solved the SASL issue too, for the interested people I will
post it tommorow.
Thanks for everyone, participating in the discussion, for their help.

Here is the link that describes how to hack SASL. Any imput is welcome
(especially concerning autotools):

It is available:
http://open-sendmail.cvs.sourceforge.net/*checkout*/open-sendmail/open-sendmail/cf/feature/anfi/vdevcot_plain.m4
Installation procedure:
1) copy vdevcot_plain.m4 file to created anfi subdirectory of
cf/feature/ directory
2) copy sendmail.mc to sendmail-test.mc
3) in sendmail-test.mc add
FEATURE(`anfi/vdevcot_plain')
LOCAL_CONFIG
C{VDovecotDomain}domain1.handled.by.dovecot domain2.handled.by.dovecot
divert(-1)
3) generate sendmail-test.cf
4) check that if "dovecot user map" works
echo '/map dovecot existi...@domain1.handled.by.dovecot' | \
sendmail -C sendmail-test.cf -bt
echo '/map dovecot non-exis...@domain1.handled.by.dovecot' | \
sendmail -C sendmail-test.cf -bt
DOES NOT WORK? => EXIT [ASK FOR ADDITIONAL INSTRUCTIONS]
5) patch cf/m4/proto.m4 with local-domain-routing.patch
http://open-sendmail.cvs.sourceforge.net/*checkout*/open-sendmail/open-sendmail/cf/m4/local-domain-routing.patch
6) generate sendmail-test.cf *AGAIN*
7) test it using
sendmail -C sendmail-test.cf -bv existi...@domain1.handled.by.dovecot
sendmail -C sendmail-test.cf -bv non-exis...@domain1.handled.by.dovecot
DOES NOT WORK? => EXIT [ASK FOR ADDITIONAL INSTRUCTIONS]
8) apply the fixes to sendmail.mc, generate new sendmail.cf, restart
sendmail daemon
P.S.
It is a trivial modification of FEATURE(`anfi/vcyrus')
