Hi, Does any one seeing increasing smtp concurrency for the past couple of weeks? I run couple of (qmail/simscan/spamassassin) mail servers and all experience the same problem. The spam does not increase, but this is hogging my mail servers. Probably a new crop of spamming tools?
I am attaching one qmail-mtrg graph that shows the problem. http://img403.imageshack.us/img403/2224/smtpmonthyq4.png raj
