Imail Analyzer has a SMTPD errors report which gives an invalid user IP
report like shown below. Does anyone have a similar report which would show
groupings by IP class (say invalids by class C) or invalids by sending
domain? That could help pinpoint "trouble" makers.
91 Invalid User IP = 208.24.219.169
60 Invalid User IP = 131.95.82.56
41 Invalid User IP = 131.95.82.55
9 Invalid User IP = 64.202.108.201
9 Invalid User IP = 64.202.108.199
8 Invalid User IP = 64.202.108.96
8 Invalid User IP = 64.202.108.99
6 Invalid User IP = 64.202.108.97
5 Invalid User IP = 64.202.108.98
5 Invalid User IP = 64.202.108.200
Thanks,
