Account Level Filter - Unsubscribe

[Evolve]

Hello,

I've set up a an account level filter to toss any email that has unsubscribe in the body.

This is what the vfilters file looks like:

#unsubscribe
if
 $message_body contains "unsubscribe"
 or $message_body contains "Unsubscribe"
 or $message_body matches "unsubscribe"
 or $message_body matches "Unsubscribe"
then
 save "/dev/null" 660
endif

I'm still getting spam emails with unsubscribe in the body. Some are as unsubscribe as links, is there a special way to do text that may appear in a link?

Anyone?

I'm still getting emails with unsubscribe in the body, link or no link.
