| Welcome to the error message from hell. This message is
probably MS's attempt at a generic, cover all bases,
message, that tells the user (you and I, the
administrators) absolutely *nothing*. The only think more
useless is the bounce message which *really* says nothing!
<sg>
The only thing that I can determine is that the message is
saying that SMTP is broken. Why, what happened, how to
fix, etc., are all unknown. I've seen several other
similar posts, there is a 'stock' set of answers:
.. 1. Invalid or missing From: field in the headers
.. 2. DNS Issue
.. 3. Bad/curropt install on IIS .
..
.. solutions include, fixing the ASP code, correcting DNS
.. settings or modify the firewall to allow port 53
.. and 25, reinstall the virtual server, reinstall IIS.
Of course, IMHO, this says nothing really, mostly because
there is no one thing that causes this error, and there is
no way to trace the problem to its origin!
In my case, I find no problem with the DNS entries, IIS
was reinstalled, and I'm on the verge of giving up and
finding a non-MS SMTP/POP3 setup, one that works. I think
the lack of resolution for this specific error (which has
been raised on the web for over a year now) is telling.
