What do you mean? When Postix sends thevalues above? > Take the "sasl_username", and use it as a key to lookup the number of > messages sent in your homebrew database.

How do I "take" the "sasl_username"? So youre solution assumes that anybody uses sasl? This is not in general true.. I have no fields that maintain the number of messages sent for each mailbox. Anyway, from my Ips there are users that use their own email addresses as sender for outgoing email (i.e.: email address in domains other then mine). With you re solution I can't manage such situations.. Could your solutiorefined to satisfy my needings? Anyway, I thought to some mechanism to point out an email als outgoing and then to input it to the policyd server.. It is possible to implemnt a such mechanism? rocsca
