I’m planning the transition to self-hosted mail. I did fully self-host mail >10 years ago, so I know how to do it in essence, but I’d like to go a bit softer now, and not host outbound myself, it’s just too annoying.
What’s your take on that? Do you self-host SMTP as well? Why or why not?
If not, what providers do you use for it (especially in Europe, or even Germany)? How reliable are they? What’s the maximum attachment size? What do you pay for it?
I self-host incoming mail and send outgoing mail using Mailjet’s free plan to ensure deliverability. I’ve used them for several years and found them very reliable. Occasionally our outgoing mail is routed to spam despite having our DKIM and SPF records set per Mailjet’s instructions. I’m not sure anyone else would be consistently better based on emailtooltester.com’s annual deliverability reports. Their maximum attachment size is 15 MB, but they don’t recommend anything over 5 MB, as some providers block anything larger than that (which I’ve found to be true).
