Qmail resending multiple times...
Hi, Just wanting to know if anyone has solved this behaviour... We are running SMTP redirects via Qmail 1.03 through to a Mimesweeper mail host. Most messages make it through quite happily but every now and then we get ones that hang around and get retransmitted, usually with the following appearing in the log ; delivery x: deferral: Connected_to_xx.xx.xx.xx_but_connection_died._Possible_duplicate!_(#4.4.2) Have been around the web to find someone else with a solution but to no avail - closest I came to was some guy suggesting to check if the source mail contained Bare CR's (think he was referring to bare carriage returns but not sure). Any ideas ? Cheers, Darren Kukulka [EMAIL PROTECTED]

It _must_ resend it.

This is indicative of the Mimesweeper machine not being able to handle the volume being passed it from the qmail machine. We've had the same issues and the group responsible for Mimesweeper (and in our case Mailsweeper) had to add additional load balanced machines to keep up with qmail. I reject their suggestion of reducing my concurrency since that only pushes the problem back to sender.

If Mimesweeper's really closing down the connection for that reason, and without returning any status code, that's an RFC 2821 violation (Section 3.9, para 2). You could hit them with that, if you're so inclined. -- Adrian HoTinker, Drifter, Fixer, Bum [EMAIL PROTECTED] ListArchive: http://marc.theaimsgroup.com/?l=qmail Useful URLs: http://cr.yp.to/qmail.html http://www.qmail.org http://www.lifewithqmail.org/ http://qmail.faqts.com/
