[sclug] RBL recommendations

[Martin Summers]

Possibly I am confused ! I know it was the "ansys.com" domain and one of
our smaller offices that was attempting to send e-mail to a customer and
that specific office IP seemed to have got itself on a spam sending
hosts list...but I really don't know the details. The only thing that
triggered my memory was spamhaus from this event....it was a while ago
now - about 3 months or so....

That doesn't sound right. Spamhaus advertise lists of spam-sending hosts
(SBL), compromised hosts (XBL), and hosts that shouldn't be sending mail
(PBL). Are you sure you're not confusing this with SPF or some other
blocklist?
