I’m contemplating taking control of my email by moving away from mainstream providers like Gmail or Outlook. What self-hosted email services have you tried, and which ones do you find most reliable and user-friendly? Are there any challenges or advantages you’ve encountered in making the switch?
Mail in a box or poste.io
Second vote for MAIB.
3rd for MIAB. I use Linode. I believe most ISP’s restrict access to mail ports so running at home is probably not possible.
This is a generalization that not useful to keep repeating. Better advice would be check to be sure YOUR ISP allows access to the ports you need.
