[MlMt] Delete local attachments by mailbox?

[Paul Hoffman]

Greetings again. My laptop's disk is again getting kind of full. I 
realized that some of this is due to me using email for file transfer, 
and some old messages still have large attachments I don't need. Is 
there a way I can select messages of a certain age and just remove the 
attachments in a way where they are removed from disk? Short of that, if 
I delete those messages will the attachments get deleted as well?
