These are simply the queue retry counts at which a notification email is sent to both postmaster and user that the email is still queued. By default xmail makes 32 retries but only slowly increases time between retries from initial period of 480 seconds set by commandline options -Qt timeout, -Qi ratio, -Qr nretries. It's probably not a good idea to change from defaults. > The problem is that with the 451 returned error from the remote MTA -- xMail > seems to have > considered this an error because it immediately sent back an eMail to the > user with > the Subject "Error sending message...".

I've just looked back through mails to postmaster and the codes 451 along with -77 are normal for email that is being blocked by greylisting and eventually sent (can't find messages for retry 6). Unfortunately they are normal from a couple of sites where mail is in effect rejected permanently. I see several cases of test emails where reason is given as eg. "unacceptable sender address" and other similar reasons that might be correctable by the sender. These are not generally problems caused by xmail.
