Quick question: How do I stop the "Messages Queued for deffered delivery" queue from filling up with email to bogus users in my domain? Every one of the 2500 messages in this one queue is to ficticious name in my domain. Some seem to be NDRs from the internet containing SPAM, and some are just straight SPAM, but all to unknown users in my domain. I have already enabled the "Filter reciepients not in Directory" option and applied it to the Virtural server. I was seeing tons of SMTP connectors but this seems to be fixed. Now I am only seeing this one queue fill with email destined for unknown users in my domain.
Can anyone help me out?
