I wrote this article years ago:
https://www.madboa.com/geek/sendmail-auth/
The configuration outlined there is essentially unchanged today. I
have it running on a CentOS 7 machine with sendmail 8.14.
The only real change is the SOCKETDIR setting in
/etc/sysconfig/saslauthd, which is now /run/saslauthd (rather than
/var/run/saslauthd). And, of course, I use systemctl rather
thachkconfig to control boot-time behavior.
Hi Paul,
I followed your guide to the letter, however I think it seems I
missed something. When I test with telnet to port 25 this is the
result:
telnet merlin 25
Trying 10.10.3.6...
Connected to merlin.ciss.local.
Escape character is '^]'.

thoughts?
Many. :-)
Check your mail log for clues.
Ensure you have a valid SSL certificate and key. Sendmail is touchy
about permissions on the key file. Try googling for
confDONT_BLAME_SENDMAIL and GroupReadableKeyFile.
Make sure saslauthd is configured and running.
Compile your .mc (m4) file with the macros distributed with the
version of sendmail you're actually running. This line suggests you're
not:
mdw1982.com ESMTP Sendmail 8.14.7/8.13.8
That's a first stab at things to try.
