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.

The trickier bit for me was stopping and restarting the whole SMTP
toolchain, which includes spamassassin, clavav, and opendmarc. Below
my .sig, I've included the shell script I use for that.

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 '^]'.
