Hi,

I would like to host my own email server.

I know the pros and cons of doing so, please do not post about the advantage or disadvantage, there is others open topics for it.

I would like my setup fit those “requirements”

  • FLOSS
  • Be able to create complex rules for incoming/outgoing email ( with 🐍 Python language preferably ).
    • based on any properties (subject, ip, header, size, attachment, signed, encrypted, etc… )
    • able to modify, delete, fw, etc… the email

 

If you know a matrix comparison between email servers I’m all ears.

If you have any feedback with a solution this is most welcome too.

I plan to update this post to create a matrix/spreadsheet of all the solutions that I’ll gather.

Thanks.

    Use Stalwart as mailserver. Besides coming with sane defaults, it allows to put hooks into almost every mail stage. Those hooks can be sieve scripts, local binaries or http calls.

      From its web page it sounds like it is both a MTA and MDA, has a built-in spam filter, plus has calendar, contacts and file storage. Do you know how it compares to my current setup of Postfix, Dovecot, and rspamd (and Nextcloud for the others)?

        Well exactly as you say: it’s a single service instead of having to combine multiple. In my case dovecot was a lot faster for my mailboxes, but postfix was a piece of shit and I was happy to get rid of it and the many components (rspamd, dkimproxy, etc.) it required. It has far too many footguns, and I shot myself multiple times with them over the years. So the most important part (SMTP) is significantly simpler and IMO better with stalwart. And the mailbox part hopefully evolves as well (it already has JMAP, so that is already an advantage over dovecot as well).
