We run proxy side antivirus and client antivirus. In our case the SMTPD service still shows as running in the services window and our internal mail still moves however external mail can not come in but can send.

I've also seen mention of another Worm/Virus that also uses it's on SMTP service: W32/Israz-B. Here's are links with info on these: http://securityresponse.symantec.com/avcenter/vinfodb.html#threat_list and http://securityresponse.symantec.com/avcenter/venc/data/[EMAIL PROTECTED] They both have their own SMTP engine for replication purposes...and we know that if there are any other SMTP services loaded on your IMail server they will conflict with IMail server...and cause the service to stop... We've never seen the problem ourselves....but this non-resolution of your issues has got me wondering.... Dennis T. Kemp II (Tom) Program Manager MCSE/CNA/A+ Control Concepts, Inc.

Our external mail will completely drop off until I restart the SMTPD service at which point it immediately picks up again. Our internal mail however is fine. I have not been able to work it out even with several calls to Ipswitch and our proxy server people.

I restarted all of the services, the queue started going down, and the machine was back to normal operation (30 in the queue) in 15 minutes. This seems to be relatively common thing for us, check the queue, if it's over a few hundred, restart the services, and it's back to normal. Anyone got any ideas? I downloaded the log and from 11:53 till 14:32 my mail server I noticed there is not a single rdeliver, but there are a whole lot of MX connect fails.
