[webmin-l] Mail Problems

[Cary R. <ca...@cp...>]

Would anybody here know to identify and block repetitive emails ?
What I'm talking about is somebody sending hundreds of emails at a time to 
one of my users. I wish it was as easy as an IP or domain block, but this 
person seems to be very proficient at spoofing an IP address. I flat can't 
find a way to identify the culprit other than setting up some kind of 
filter that recognizes many repeats of the same message.

Any help or suggestions greatly appreciated

Thanks,
Cary Robinson

ps... Jamie,
Great book. Between Your's and Joe's books, I have been tackling all kinds 
of configuration issues that I have put off for a long time. The books 
really make it easy.
