Dear users, today an user told me he was recieving too many spam in a
very short period of time. I took a look at the log files and what he
told me is true. :(
But... it just happens to him, nothing else is recieving spam. The
server is running Postfix + SpamAssassin + Clamav and the filters
seems to run fine. I can see many warnings about blocked spam.
The symptons are too many connections trying to send mail to this
user. Those connections come from all over the world.
Any suggestion?!
Greetings.
If these are non-delivery notices of mail he didn't send, see the
BACKSCATTER_README for suggestions on blocking it.

Thank you... it's really backscatter.
Let's work with it now.
Greetings.
