Method for incoming emails

[Fabian Jäger]

Dear Mail experts,
I am currently planning a new plugin that would need to react on incoming emails. Therefore, I was wondering whether somebody has a good entry point for a method that is called whenever a new email is being received by Mail? The optimal case would be a method, which has full access to the email's content, including attachments ... the plugin would also require to be able to change the email's body on certain conditions.

Best regards,
Fabian

one of possible ways is to add a rule which runs applescript - use applescript to modify message content (to the full extent, I believe) and you can also use applescript to create a rule itself from installer.
