In case there's any doubt about whether or not the Botnet plugin tripped
up on the PTR record situation (and someone used that as a basis for a
tempfail), here's the output of Botnet.pl for that IP address:


% Botnet.pl 74.254.46.133 visioncomm.net
Botnet Version = 0.8
checking IP address: 74.254.46.133
BOTNET_NORDNS: not hit - mail.visioncomm.net
BOTNET_BADDNS: not hit - hostname resolves back to ip
BOTNET_IPINHOSTNAME: not hit
BOTNET_CLIENTWORDS: not hit
BOTNET_SERVERWORDS: hit, matches=mail
BOTNET_CLIENT (meta) not hit
BOTNET_CLIENT (code) not hit, tests=none
BOTNET_SOHO: not hit
BOTNET (meta) not hit
BOTNET (code) not hit, tests=none




So:
a) Botnet wasn't mislead by the PTR alias
b) None of the Botnet tests flagged this as a Botnet (the one hit was
for "server words" which would have helped you, not hurt you).
