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.

    See my personal notes. I do selfhost mail server, but on a vps to have a good IP

    Being doing so for 20+ years and recently rebuilt the entire stack.

    See https://wiki.gardiol.org/doku.php?id=email%3Astart

    In short, I use postfix+dovecot, with opendmark and opendkim. Setup proper DNS email specific records and a few more steps.

    Overall it runs fast and perfect on 4gb ram very old dual core atom CPU.
