Hi all.
For those of you who are interested by using Poprelayd, I just made a fix today for using Dovecot and sendmail with poprelayd. Poprelayd allows you to log the IP addresses of people logging in through POP and allowing them to send e-mails using your smtp server (allowing relaying) for 15 minutes. It is very handy. You can download the parser here: http://sourceforge.net/forum/forum.php?forum_id=21494
It is just a little info that might be useful for some people.
Kind regards, Daniel
