I know its basically the standard but its a pain to configure and modify. I recently started to work with Haraka and its so much more of a plessure (even thought i am no JS fan, i prefer JS to cryptic/ancient config files)
Just curious if you went through a evaluation process
I have basically no experience with Javascript or web stuff, and the last thing I want to do is figure out some leftpad-style NPM package dependency while my mail server is down. Maybe I'm just an old-school Unix guy at heart though - running a JavaScript interpreter on a privileged port just doesn't sit right with me.
Postfix is a breeze to work with in comparison.
I've setup both multiple times, and have worked with Sendmail since 1994. Postfix config files are much simpler.
To configure sendmail, you have to do extra layers of weirdness, like deal with "m4". That's mental overhead you just don't have with Postfix.
The relative complexity of the files is about the same—my postfix server config is roughly the same number of lines as my sendmail server config. And each line is just a single conf thing. Sendmail isn't really more complicated at all. It's just ugly.
Do you use it together with an imap server (like dovecot)?
