Hosting vm-pop3d style virtual domains

Introduction

Here’s what that format looks like.

/etc/virtual/DOMAIN/passwd
/etc/virtual/DOMAIN/aliases

assuming Maildir

/var/spool/virtual/DOMAIN/USER/

Postfix doesn’t support that format very well, but Dovecot does, so we could LMTP to deliver the messages, and without even the need for Dovecot’s LDA. However I prefer the idea of Postfix not having to rely on anything but itself (but the procmail binary).

Postfix + Procmail to handle virtual domains delivery

See postfix-vmail

Dovecot to handle virtual domains authentication
