I have qmail configured to check only relays.ordb.org and bl.spamcop.net -- I intentionally avoid spews specifically because of its reputation and listing policy. However, I did misinterpret the bounce message. What it said was this: There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. smtp;554 Service unavailable; Client host [65.244.125.66] blocked using l1.spews.dnsbl.sorbs.net; ! [1] Reinertsen, see http://spews.org/ask.cgi?S1519 So... the message was rejected because of the SPEWS zone at SORBS. The weird thing is this: I sent myself another message this morning and it came right through. So I'll have to assume that some interim hop blocked yesterday's message and I certainly can't do anything about that. It's times like this when all I can do is curse Microsoft for hiding everything I need to track down why this happened. Thanks to everyone who responded for their suggestions.
