spammers using sm-msp-queue to relay emails

Asked by rdhewitt in SendMail Email Server

I am running sendmail 8.12.10 on a redhat 3 Linux system. Just recently my number of sendmail processes have jumped from a couple of hundred to a couple of thousand loaded in memory at any onetime. I have also noticed in my maillog a lot of these type of entries below:

Sep  5 20:28:16 ns sm-msp-queue[22574]: l85Ic4BK031966: to=<jqoww@weber.edu>, delay=05:47:23, xdelay=00:00:00, mailer=esmtp, pri=1023880, relay=fielding3.weber.edu., dsn=4.0.0, stat=Deferred: Connection timed out with fielding3.weber.edu.
Sep  5 20:28:16 ns sm-msp-queue[22574]: l85IgJAi004757: to=<jqoww@weber.edu>, delay=05:40:10, xdelay=00:00:00, mailer=esmtp, pri=1023927, relay=fielding3.weber.edu., dsn=4.0.0, stat=Deferred: Connection timed out with fielding3.weber.edu.

I have traced these to my out queue any they are spam emails but I can not tell how these emails are able to relay through my sendmail.

Any insight on how to stop this would be great?
