Postfix Drupal mail queue problem

Posted by lapurD on January 22, 2010 at 11:59am

My postfix mail queue is full with mails that cannot be send because of wrong address. For example:
(delivery temporarily suspended: connect to wrong.moc[260.260.260.260]:25: Connection timed out)
For one day number of these messages increase to more than 2000. I delete them with
postsuper -d ALL
postsuper -d ALL deferred
but after 5 minutes they start to fill the queue again!
These 2-3 wrong addresses was entered by me when I configure my Drupal installation. Now there aren't users with these e-mails but something (most likely Drupal) is still trying to send messages to them.
I use Debian. Here is my masked syslog:

I have the same problem but in ubuntu and the emails where not entered by me, it seems like if a robot was sending emails.
Any solution?
Thanks!
