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!
