Understood. And I apologize. I assumed because of the old version of your
existing installation a less actively maintained situation and made a snap
judgement about your experience.
I also never said sendmail is not a solid MTA. I stated it is extremely
difficult to maintain.
Also other MTA are well suited for high traffic servers. Exim is used
by ISPs with extremely high traffic.

Well, in my previous post I might hinted at your issue.
Please check if courier-authdaemon or dovecot-core is installed.
Both provide an sasl authdaemon.
I do not know anything about your old installation so you have to
figure out, how and where the unix socket of the daemon is located.
If you use a chroot environment you must make sure the socket is accessible
to sendmail.
My apologies for the top post. We use Google for our institutional email, and the Gmail interface defaults to that when I reply to a message.
Looking at the existing Wheezy server which works correctly, I do not see anything providing an auth daemon besides saslauthd:
# dpkg-query -W | egrep 'sendmail|sasl|courier|dovecot'
libsasl2-2:amd64 2.1.25.dfsg1-6+deb7u1
libsasl2-modules:amd64 2.1.25.dfsg1-6+deb7u1
sasl2-bin 2.1.25.dfsg1-6+deb7u1
sendmail 8.14.4-4
sendmail-base 8.14.4-4
sendmail-bin 8.14.4-4
sendmail-cf 8.14.4-4
So I guess my question is, do I need one now on the Bullseye server, if saslauthd always worked for this before?
Thanks,
Dave
