Thank you for your input.

I already suspected that i would have to use LDAP to be able to validate 
the user, but i'd like it to be a last resort effort.

As for my concerns regarding IMAP. Can you confirm that i will be able 
to apply those rules both for POP and IMAP? I'm asking because the 
mapping i tried with popmap only worked for POP access.
