sendmail does store-and-forward by default when it is in the
queue mode.  (O DeliveryMode=)

The choices for delivery mode include interactive, background,
and queue.  The latter two are store-and-forward - the last
one requires that something happen to cause the queue to run
(like a cron job that makes sendmail -q run), or else -bd -q5m 
on the command line, to cause it to run the queue every 5 
minutes when running as a daemon.  (You can set whatever queue 
interval you want of course.)

Do you know why your mail program (MUA) puts this huge obnoxious
header in every e-mail you send out?  I think it is all one line.
It'd be good if you could turn that off.
