Hi, i have the pdf rules up and running
they are working nice.
But i didnt recieved any pdf spam since days.
On our big back mx mail hub , clam ( with some additional databases)
gets delete ca.
10 of them a day.
I think we will see other spam in the future
in other file sorts, and it will always be a competition
between spammers and antispam tecs.
I think we will never avoid spam in total as long smtp
stays for mail, but we can make more difficult for spammers
to reach there goals , so i recommend take it easy, no need for
flames between the good boys
http://sanesecurity.co.uk/ is working nice if youre in pressure
with pdf spam
Mit freundlichen Gruessen
