This looks like a familiar problem , Here is some cases in which this can occur.
1) Even the T-1 connection seems OK ,you should check it again , sometimes modems get connected but because of the poor quality there can be some data corruption at high data transmission . Check a continous ping to the router address , send at least 100 ping packets to see if there are some packet loss.And also make a download from a ftp from a near location to check the speed. 2) Second possibility , There is a misconfiguration in your firewall . As i dont have enough information about the firewall ,check if the firewall intercept the smtp protocol. Or if there is a bandwith limitation . If you can provide more information about the system , i can help more Regards Rifat Levis ----- Original Message ----- From: i360 To: [EMAIL PROTECTED] Sent: Tuesday, July 22, 2003 11:58 PM Subject: [Declude.JunkMail] Email with attachments kills the connection I have an interesting problem. One of my clients does have a T-1 with AT&T. When they send emails with no attachments it works fine, no problem at all but when they attach an a file and it does not have to be more than a few K's they get a timeout when sending emails. If they send from any connection outside that T-1 everything works fine and if they send from any of the other T-1's they have with AT-T it works fine too. ATT is pointing the finger at us of course. The latest thing is that we don't have their reverse DNS set up right but the we don't check for it and if that was the case all the email should be rejected. We even replace their firewall just to satisfy ATT with no luck. Does anyone have any suggestions, I am at a loss.
