Gerry,
If the IP changes and is within a 'block' of addresses, You could use the
SMTP Security, Control Access button and enter a 'group' with the IP and
subnetmask that will block a whole range of IPs. (Addresses in this list
will not be allowed to connect to the SMTP service). Read settings
_carefully_, as incorrect setting will block everyone else! Leave the radio
button for 'Granted Access' as is (checked). This might cause the ISP
issuing the IPs to be unable to connect to your server, but that might force
them to contact you and you can then tell them of your troubles. Maybe they
can then trace the offender and restrict his access. Maybe they just do not
care.
