I ended up with mailu.
What got me interested is their integration with traefik. It just worked. Not without 9 hours of finding out the right proxy settings, but know I'm attached to it like to IKEA furniture.
On a more serious note, they showed an example of properly proxying a imap/smtp SSL connection. If you asked me before integrating it, I'd have thought it might be impossible, since SMTP has some STARTTLS negotation baked into protocol.
I only knew how to proxy SSL in HTTP and never knew that bare TCP can be used to PROXY and terminate tls as well.
