Are you actully getting any email from that address? the fact it changes
slightly, and   the fact the address has no reverse DNS kinda suggests
it's a dialup address...someone might be messing with you...

add 204.71.191.* to /etc/hosts.deny
and no one from that address range will be able to connect at all
(won't prevent some nastier things tho)
