Re: [seul-edu] Mail Filters

[sala@cbint.org]

Ok, i posted to the list a while ago some procmail filters that disabled
the executable contento on email messages. I think that the filters
could be modified a little to block .doc, .dot (templates) and .xls
files. The url is 
ftp://ftp.rubyriver.com/pub/jhardin/antispam/procmail-security.html (It
works for the thing it's done for, i sent myself the iloveyou virus, and
it was stopped. Nice)
