No HTML from what I can tell but I'm using Outlook too.
The damn thing cleans out my mail box on the server when filters are set
up or I would open it in netscape and tell you for sure.
Thanks for the explanation on the acronym, they kill me.

Heh, AFAIK, it means "As far as I know" (which sometimes isn't all that
far.

By the way, are messages from me coming out in HTML or some crap like
that? I admit to using Outlook (I'm at work...) and though I've got the
fscking thing set to plain text in two different places (and messages
appear to be plain when they go out), when it comes back the text is
proportional and smells very non-plain.

I had read that and came to that conclusion. But, what on earth
does AFAIK mean? This is the 3rd or 4th time I've seen that.

AFAIK, there is no such thing as a port in ICMP. ICMP packets
are demultiplexed by IP based on the value of the protocol field in the
IP header. The network stack is what responds to a PING (really an ICMP
echo request packet), not any particular application.
