Do AppleScripts invoked by Mail filters have access to the e-mail(s) that matched the filter?

Question

I’m setting up a filter in Mail on OS X that calls an AppleScript whenever an e-mail sent to a specific e-mail address arrives.

Will the AppleScript get passed/have access to any of the e-mail’s properties? I’d like it to take different actions based on the “from” e-mail address.

Answer 1

Yes: if the script invoked by the filter has a perform mail action with messages handler, then the messages argument will be populated with a list of the messages that matched the rule.
