A reliable mail stack is configuring postfix+dovecot or cyrus, adding dspam, opendmarc, opendkim and a bunch of dns records.
How is this any harder than anything else in computing?
- tshtf 11y agoDKIM + SPF + DMARC does not guarantee reliable delivery. Not even close.
- pmlnr 11y agoOf course not. However, in the past ~7 years, while running my own mail stack, I never had a delivery issue, though obviously this is small traffic. At work, we handle pretty large traffic for mail, with self-hosted mail servers as well - those are exim. No delivery issues either, although these are only the real, important, not even remotely spam-like, core business messages. Spam-like newsletters are done via sendgrid there.
