-Sometimes you want
-.B sendfiles
-to pause after posting a partial
-message. This is usually the case when you are running
-.B sendmail
-and expect to generate a lot of partial messages. The
-.B \-delay
-switch specifies the number of seconds to pause in between postings,
-e.g.,
-.PP
-.RS 5
-sendfiles -delay 30 -to recipient -subject \*(lqsubject\*(rq files\0...
-.RE
-.PP
-will pause 30 seconds in between each posting. An alternate form of
-the switch with just the delay time,
-.BR \-30 ,
-for example, is also supported.
