Sometimes. Lots of ISPs and sites want over-quota to issue a PERM FAIL. And my experience is that I've gotten a lot of 5.x.x bounces back because someone is overquota. There are several rationals for perm fail; I don't like any of them, but then, I don't like spam and mail bombs. > The SENDING sendmail will continue to try to deliver the mail until the > queue timeout, normally 5 days (but I've seen exchange servers set as > low as 4 hours...).

I believe that's against RFCs (or likely a SHOULD rather than a MUST), but then, "Microsoft doesn't follow standards, [they] set them!"
