Indeed, the cruft was in the retention of support for long obsolete
features such as UUCP mail and address source-routing.
And as sendmail.cf became entirely too unwieldy, they "solved" it
my adding a completely different "high-level" configuration language
in the form of M4 with option names that were similar to the ones
in sendmail itself, but spelled slightly differently.
I never got the hang of writing in sendmail.mc, preferring to hand
edit sendmail.cf, but only in areas where I needed to (which
were very rarely needed and confined to a single line at a time.
So when I needed to look more closely, I now had to explore the M4
and rebuild the CF file.
Postfix also has a lot of possible configuration, but it was
surprisingly easy to get a basic configuration up and running.
At this point, I would suggest that anyone still running sendmail
on a workstation take the tie to bring up postfix at a time when things
are working well, so that the challenge of learning postfix is not
layered on to of time-critical debugging when something fails.
