If [all] conditions are met :
[To] [Contains] some.list@listserver.org
[Subject] [Contains] Re
[Message content] [Contains] YourName
Then I added some Actions to it. I used a color and a sound, as seen in this screenshot.
Notes:
- some.list@listserver.org is the address of a mailinglist (duh ;-)
- YourName should be the name you have in your addressbook. If you call yourself "Steve Jobs" a reply usually includes the line "Steve Jobs wrote:"
- Re, we're only interested in replies.
