The distribution can take place as individual files with a customized
'To:' field or as a single file for everyone, depending on the syntax of
the job. To get the one-file behaviour, specify 'BSMTP' where you would
put the full name of the recipient. I know it's not very intuitive, but
it was the only way to add this function without breaking older servers,
and DISTRIBUTE is a mostly internal command which was never supposed to
be user friendly.
