The pause wouldn't matter. If you are using the sendmail interface, the
only thing that happens to your mail is it gets written to a file in
/var/spool/postfix/postdrop/. The pickup daemon pulls messages from that
directory whenever it has time, so the pickup daemon does all of the dirty
work. You don't have to worry about pausing at all. The pickup daemon
will pause if it needs to.
