DavidT Posted January 30, 2008 Share Posted January 30, 2008 Please start by reading this topic: http://forum.spamcop.net/forums/index.php?showtopic=9116 The issue that arose in that topic, is that when an SMTP connection comes into the MX for SpamCop.net email accounts, and asks to deliver to a bad address, SpamCop's server is currently producing an unusual (IMO) "double error" like this: 550 sorry, no such user here (#5.7.1) 553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) A delivery attempt on a bad address should only produce the "no such user" error, and not the "domain isn't allowed to be relayed" error, which has an altogether different purpose. This seems to be a bug and so I'll send it to TPTB (i.e. JT). DT Link to comment Share on other sites More sharing options...
