Ok. Here goes:
First, you must have a mailerdaemon installed. I'll assume you'll go with
the default sendmail-install.
Then you have to change the line which says HoldExpensive to True.
Then change all the Mprocmail, Mprog, Msmtp, lines to include 'e' in the
options-line.
All the Msmtp should have e, but prog and procmail should not have.
Example attached...
