Seems quite nice compared to bloody scheme

I'll be repeating what's said already but coming from someone who hosts his own non critical email

VPS Either with a TCP reverse proxy back home comming in on an other port (seems most compatible with mailcow at home)

Or hosting postfix on the vps, you could still do IMAP at home

I can see your point but in my native language nobody has heard of gimp compared to crackpipe
