I need to run my own email server for some of my domains, because the providers that I usually use don’t support them (they use Unicode characters, and not everyone supports that yet). I have a small VPS that I run a few Docker containers on, and I’m wanting to try and run an email server on it as well. What containers are good for a low-hassle email setup? I don’t need a mailbox webui (ex: round cube), but it would be nice to have a UI for management. I do need multi-domain support, however.
Yes, I migrated IP (from one provided to another) last year, and I recently added a new domain as well.
The new domain on the new ip just works, and the old domain on the same new ip just keep working.
Both the old and new ip are not residential IPs, I rent a small dedicated server for this purpose on the major hoster of my country. I pay about 15€/month for that, but it’s not only used for email, for all my services.
