James R. Cutler [05/04/07 16:30 -0400]:Todd makes my point exactly. As he notes, the rejection message tells me that the message was rejected by some system. It does not tell my why it was rejected. Thus, just like this message, it adds more to the noise to signal ratio!Has anyone ever thought of standardizing the 500-responses from the DATA phase? For instance, maybe 571 could always mean "rejected because of the spam filter". If there was a standard for these response codes then maybe clients like Microsoft Outlook could do something useful with the error message. Regards, Ken
I had a good chuckle after reading your message. It's a great suggestion BUT... Microsoft products already ignore 5xx responses. From what I've seen, Outlook and Exchange will indefinitely retry a message after receiving a 5xx error. Outlook keeps the message in the user's PersonalFolders/Outbox for subsequent delivery attempts when you hit Send/Receive. We've seen lots of clients here attempt to send the same message every minute for weeks when the message exceeds our message size restrictions. Have they recently fixed this or released patches for all older product versions?
