Thank you most sincerely for this message (and your other comments in this
thread). It's nice to know that the company's working level understands the
problem.

Ah...thank you. I might well try restricting the block against Tiscali to
those machines.

Actually, Tiscali was only the trigger to doing our exemptions via a MySQL

a new entry in the table than to mess with the ACLs. We use the same
database to carve out needed exemptions to Spamhaus blocks.
