Title: Mail filter for 'From:' or 'X-From-Line:' or 'Reply-To:'
Post by: yerill on April 24, 2011, 06:53:33 pm

Hi,

I'm receiving mail without a valid  'From:' or 'X-From-Line:' or 'Reply-To:'.  I believe it get's past my ISP (bellsouth.net) because the header contains "From" without a ":". 

Example:
From  shopping@one.yahoo-email.com Date: 2 Wed, 2011 Feb

How do a craft a filter to tag these as possible spam?

Thanks!
