I've seen something similar with Norton Anti-virus running on client pcs. A person would start a pop session, the anti-virus software would scan, hang the pop session, and time-out. When the person would go to pop their mail again the message would come in again. I believe the software now supports an "anti-timeout" feature to help prevent this from happening, but I have someone I work with who has this feature enabled and still runs into the problem ... granted it is when he's popping 4000 messages in a single session after being away for a week at a time.
See if you can get these people to send you headers ... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Atkinson, Milt Sent: Thursday, July 06, 2006 12:49 PM To: Exchange Discussions Subject: RE: Multiple e-mail's Had the same issue with users that were using Symantec virus scan. Check and see if scanning on outbound email is set. If it is, turn it off. This fixed our problem. ________________________________ From: [EMAIL PROTECTED] on behalf of Mark Condron Sent: Thu 7/6/2006 10:11 AM To: Exchange Discussions Subject: Multiple e-mail's All, Exchange 2003 SP2, Windows 2000 SP4, 2MB leased line. We have a number of quite large e-mailings (1000+) that we send out periodically. It seems that some recipients (it varies) are receiving multiple copies of the e-mail, usually 3. I have checked the database extraction and the e-mail before it leaves and I am certain they are only set as a recipient once. I have also checked the tracking logs and again the recipient is only listed once. I limit the number of connections to 50 and have a timeout of 15 minutes and Outbound retry is set to 1st 10 minutes, 2nd 10 minutes, and 3rd 10 minutes. As it is various recipients and this changes with each mailing I feel the issue must be ours. Is it possible that during the transaction when real busy that our server sends multiple copies, is this possible during the transaction? I guess I'll trawl through the SMTP logs and try and find something. Any pointers on where else to investigate appreciated.
