[Dovecot] postfix+dovecot

[eLgino]

Hi folks,

I will setup an mailserver with postfix an dovecot, but i would like to add
the users and domains to postfix is this possible? because postfix can
handle mysql. and if this possible anyone can say me HOW?, i do not find
anything about this. if not anyone can say me how i do configure it with
postgresql (dovecot)? ( i have NO pgsql skills).

i hope anyone can understand my poor english, and thx in advance

bye
