[AccessD] OT: email

Does anyone know if email can come from a url that will not display in i.e?
IOW, if can I get email from Somebody at mx5.1premio.com if when I put
www.mx5.1premio.com I cannot display a page?

On the face of it I would think that is possible.  A person could set up a
web address just to send spam and have no valid web page served up for the
url.

BTW, an update on SAProxy, the spam filtering program I have been
discussing, I have found blacklists out on the web that increase the
accuracy of my filtering.  I have written a little program to import all the
addresses of a blacklist into a table with a unique index on it, then write
that table back out to a config file for SpamAssassin.  This allows me to
accumulate blacklist addresses from published lists while insuring that no
blacklist address ever gets looked at more than once.  It seems to be
working.  I'll let you know what the new figures show for filtering, but I
am already getting spam removal based on the fact it is in my blacklist.
