Yeah, I noticed that I can access the mailbox like any other. Simply piping the message through sendmail should then do the trick then. The remaining I have (see the other sub-thread) is setting up the local MTA on OSX so that it relays mail through an authenticated and encrypted SMTP session. But that's not a mutt problem anymore.
