Hi,

We are running MailScanner 4.43.8. Our message size limit is 50M. I 
noticed a valid message was stuck in MailScanner for over an hour. The 
server's load was very high and email processing was very slow. 
Eventually I had to move it to the delivery queue manually. Does anybody 
know what's the best practice for this situation?
