postfix queue filling up (from sendmail?)

What is filling up my postfix queue (/var/spool/postfix/deferred/)?

I had a perl script running via crontab to monitor my IP connection and send me a mail via sendmail. Now I have a huge queue of emails I keep getting. I've removed the crontab and the script. If I clear out /var/spool/postfix/deferred/, it gets repopulated. What is routing the messages here? How can I stop it?

(/var/spool/mqueue/ has always been empty)

Thanks!

Run 'mailq' to see what's currently in the queue. Run 'sudo postcat -q <message_id>' to see the contents of a particular message. That should help you diagnose where they care coming from. If they are coming from cron it will say so somewhere in the headers.

You can clear the deferred queue with 'sudo postsuper -d ALL deferred'
