[Dovecot] proxy_maybe regex

[David Halik]

Does anyone know if dovecot support regex lookups for proxy/proxy_maybe, 
rather than mysql/ldap etc?

I've been comparing it with perdition to see which one might be better 
for us to do layer7 username switching.

Perdition supports the ability to not have any auth/db looks, but rather 
just a regex file that parses the usernames as they come in and forwards 
to the particular machine on the same port.

For example:

username:host
^[a-d]: 192.168.xxx.1
^[e-k]: 192.168.xxx.2

and so on...

I didn't think this was supported in dovecot, but I wanted to check 
first. I think this is going to end up being what we use to avoid NFS 
problems. It's lightweight, drops into our current setup, and doesn't 
require a mysql database which adds another point of failure.
