Be shure that you don't have the email adress in any (hidden) form
field and that the recieving mailing script will not accept domains
from a page. To be shurte, the allowed adresses must be hardcoded in
the script!
If not it is very easy to create your own "form" and send it to your
script.
I see formail attacks very often. Many spammers scan for formmail.php
...
So use a Intrusion Prefvention System to filter this out (Block all
formail.php? with an @ in the parameter... -
we use the powerful and cheap Tiny personal Firewall - But I am shure Black ICE
for servers will do the same.)
