Lockdown installs urlscan. Find urlscan.ini and open it, rem (;) out the
items you want to allow, restart the WWW or reboot. That should fix it. I
have had to rem out ; : to allow certain emails to open many times.

Ah, a ray of light in the darkness. I haven't installed
any package called URLScan, but I did install IIS Lockdown
tool using the SBS 2000 server default template. Could it
have been that?
Will try it again in the morning when I'm back at the
office. It's 7:30pm and I'm at home drowning my SBS
sorrows with half a bottle of mead. This onesh for you,
hic!
I was thinking of getting a script written in VB which
stripped out illegal characters in the subject header and
replaced them with a "-" or something, but if you are
right I won't need to.
Cheers Ears :)
