There's a bunch of options: https://github.com/awesome-selfhosted/awesome-selfhosted?tab=readme-ov-file#communication---email---complete-solutions https://github.com/awesome-selfhosted/awesome-selfhosted?tab... I personally use docker-mailserver https://docker-mailserver.github.io/docker-mailserver/latest/ https://docker-mailserver.github.io/docker-mailserver/latest... because it's a pretty traditional stack (postfix+dovecot+sieve etc) just already containerized and configured, so there's a lot of info already out there on how it works The number 0 requirement that you have to solve regardless of stack though is to get an IP with a good reputation. I've got Comcast Business to my apartment, which I think is probably the best way to get a good IP since it's relatively difficult for spammers to have used it in the past. Alternatively, relay everything through Mailgun/SES/whatever
