Integrate postfix+mysql with egroupware

Hello all.

Is there any easy way to make postfix work with the MySQL schema of
egroupware. I’ve installed egroupware on a debian sarge.

The MySQL DB has this table that could work

phpgw_account-> account_email
phpgw_account-> account_pwd

But I miss some camps like the maildir, homedir, uid,gid

I’ll try to modify the table and add what I need, but if someone has a
better idea
