Once again, spammers and other unsavory folk are sending out malware via attached .zip files.
How can I set up a message filter in Thunderbird 24.5 (the current version) that affects only those messages with a .zip file attached?
The closest advice I've found so far is a forum discussion about a method that apparently only works in Thunderbird 23, but it looks like they're filtering based on the presence of ".zip" anywhere in the body text, which isn't quite right.
