Message Filters
How can I leave a particular email on the server (not download it) using Message Filters or an other method.

Filters specify what to do, not what to not do. I presume this is a POP account.
Yes it is a POP account, and I do want to specify what to do and that is to leave specific mail on the server.
This article gives info on doing that: http://kb.mozillazine.org/Download_only_certain_POP_messages
