Mark expensive delivery agents All versions
The sendmail.cf HoldExpensive option (?§24.9.55 on page 1036) tells sendmail not to
connect to expensive delivery agents. Instead, mail destined for those agents is queued for
later delivery. This F=e delivery agent flag marks a delivery agent as expensive.
For example, consider a site connected to the Internet over a dial-on-demand ISDN link
that costs lots of money per minute. Such a site might want all the Internet mail to be
queued and would arrange for that queue to be processed only once every other hour.
Under V8 sendmail, verbose output (watch delivery) cancels the effect of the F=e delivery
agent flag (suppresses queueing).* Verbose output is set withth e -v command-line switch
(?§6.7.47 on page 249) or the Verbose option (?§24.9.129 on page 1117).

Many Unix mail-reading programs, suchas /usr/ucb/Mail, require that each mail message in
a file of many mail messages be delimited from the others by a blank line, and then a line
that begins with the five characters ???From ???:
and thanks again. -- bill ?†? one message ends
?†? a blank line
From george Fri Dec 13 12:03:45 2002 ?†? next message starts
This means that any given mail message can have only one line in it that begins with the
five characters ???From ???.
