My queue is horribly backed up with over 4,000 messages and I can not figure out how to shrink the queue. I do not have a bunch of MAILER-DAEMON notices, I do have strange domain names in the mailq list and handful of temporary failure messages. The issue is getting worst by the minute. I followed the article here: http://www.postfix.org/LOCAL_RECIPIENT_README.html and I think that we are good as far as those settings. Any insight would be great as email is severely delayed. Here is some data on our postfix setup:
