Postfix (or Stalwart) seems to the FOSS community's preferred SMTP server, at least for incoming mail.
What do people like about Exim? I know my mail provider uses Exim at least.
I recall Debian installs it by default for outgoing mail, e.g. as sent by cron/SMART.
Is /usr/sbin/sendmail still a practiced method of alerting? I see part of the appeal, but also don't have much confidence in the deliverability of mail from random servers. I know if I do the SPF/DKIM/DMARC dance then deliverability will be okay, but to do it for each of my servers? Or are admins configuring smarthosts, i.e. authenticated submission, but then... with what sender credentials? Their personal email? A service account?
Back in the day I picked Exim over Postfix because Postfix couldn't reject unknown local recipients or spam at SMTP time. Rejected mail would end up as a bounce in the local queue. And I think there were some rewriting rules that I couldn't find a way to do with Postfix but were easy with Exim.
Note that this was a long time ago and modern Postfix can probably do all of these thing just fine. I know that it has gained the ability to reject unknown local recipients shortly after I moved on from it.
Today my choice is "neither", instead go with something as small and simple as possible with a codebase I can fully understand. But that's what I do for all of my services now.
