[TriLUG] spamhaus enforcing limits on connections

[Jason Watts]

My company is a reseller of Message Labs.  from the dealings I have had with
their tech support, they are pretty sharp.  It also seems to do a fairly
good job of filtering email.

If you don't want to worry about it, let me know off list and I will get you
to a sales guy here  (sorry, had to try to get the advertisement in.)
