Find selected messages in Fastmail

Find selected messages in Fastmail is a free AppleScript based tool created for Fastmail users who also use Mail.app.

Find selected messages in Fastmail is an easy to use script that searches for the selected messages (in Mail.app) in the Fastmail web interface.

Why would you need such a thing? One reason is that Fastmail lets users specify an infinite number of aliases which they can give to an infinite number of websites (and subsequently block, if an infinite amount of spamming ensues).

Mail.app doesn’t offer a good way to change your reply address, but replying from the Fastmail web interface does the trick nicely.
