We use Dovecot proxy feature in a quite large production environment (around 1.5
millions mailboxes). We have a maximum of 220 connections / second (2 minutes
average) on our environment and dovecot is running for several months now
without any major problems.

We have some experience with perdition too. But I recommend using dovecot over
perdition. Dovecot is much more easier to setup.
