Yeah for normal outbound email volumes SES is probably the way to go. BTW if you don't go with PretzelBox consider the following for running mail: https://github.com/foxcpp/maddy https://github.com/albertito/chasquid https://github.com/mail-in-a-box/mailinabox https://github.com/Mailu/Mailu I personally use maddy and it's awesome

I run my own mail servers for small projects, though for my main email I've actually switched to ProtonMail (previously dovecot + postfix). It's never been easier to self host your email with projects like the following around: - https://foxcpp.dev/maddy/ - https://github.com/albertito/chasquid - https://github.com/haraka/haraka - https://github.com/mail-in-a-box/mailinabox - https://github.com/Mailu/Mailu Of course the usual dovecot + postfix setup is great for learning even if a bit complicated.

There are some really interesting choices for F/OSS email servers these days. There are SMTP+IMAP: - maddy[0] (I use this) - chasquid[1] - docker-mailserver[2] And combinations: - haraka[3]/ZoneMTA[4] (SMTP) + wilduck[5] (IMAP) Modoboa brings something new in that it bundles together the frontend but I'm very happy with Thunderbird (and there are other frontends like Sogo) -- the competition is stiff and modoboa really could use a front-and center image of what the app looks like on the main page. [EDIT] I forgot two! - iredmail (https://www.iredmail.org/download.html) - Apache James (https://james.apache.org/) [0]: https://maddy.email/ [1]: https://github.com/albertito/chasquid [2]: https://github.com/docker-mailserver/docker-mailserver [3]: https://haraka.github.io [4]: https://github.com/zone-eu/zone-mta [5]: https://wildduck.email/

Maddy is fantastic -- for greater flexibility/ease of deployment, you can pre-provision your DKIM keys as well. Maddy also works wonderfully when combined with other technologies, it's nice, simple and light. It works great with Haraka[0] on the outside proxying email to maddy instances on the inside. I've also combined it with SES provisioned with Pulumi + k8s[1] (for those on AWS), which is a little bit more involved but is what I use on projects now. Another entry in this space is chasquid[2] but I've only used/can recommend maddy. Maddy is so good it makes me think anyone could run a hard-multitenant email provider with ease (I'm essentially doing that for each of my projects).

I strongly recommend looking into Chasquid: https://github.com/albertito/chasquid Only SMTP though, for the IMAP part you need to use something else like Dovecot.
