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
• Manage the limit of sending by size and number of outgoing over time (min, hours, week, etc…)

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.
