Cannot receive email from specific address
Posted on 2007-11-16
I have a customer who is routing incoming mail through softscan (managed spam solution) which for some reason is unable to deliver mail from one specific email address to their Exchange 2000 mail server, fails to deliver the mail with the following error:
reason: "IP" failed after I sent the message. Remote host said: 554 Transaction failed
Other email addresses from the same sender domain get through fine, just this particular email address. When I try to send a test mail spoofing this email address through telnet I get the following error:
554 Unable to process message: msg.1195215309.247295.4273 - error: Illegal breakage found in header: <Test_>
If I try the same test without putting any data in the mail it gets queued for delivery. Has anyone come across this error before? Incidentally I get this same error when I try putting any data regardless of the sender email address. Thanks in advance.
