Yup, just need to send this attachment.

Well, I can't see the output as its ran by the daemon, I just try try
to run as a user whom also doesn't have a local mb and get prompted
which to create a new mb.

Just before I could look into Mike's reco, someone on the mutt list
presented what just might be the working muttrc conf I needed.

-f /dev/null and 'set folder=/dev/null' looks like what I was after.

I should have the machine back up for testing tomorrow...
