Synopsis
Many Unix mail-reading programs, such as
/usr/ucb/Mail, require that each mail message in
a file of many mail messages be delimited from the others by a blank
line, 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
“. To prevent such lines from being
improperly fed to such mail delivery agents,
sendmail offers the F=E
delivery agent flag. This delivery agent flag tells
sendmail to insert a > character at the front
of all but the first such lines found. Consider the following:
From tim@here.us.edu Fri Dec 13 13:00:03 2002 From now on, let's meet on Saturdays instead of Tuesdays, like we discussed.
If the F=E
delivery agent flag is specified for
the delivery agent that delivers the preceding message,
sendmail converts it to read:
From tim@here.us.edu Sat Dec 14 13:00:03 2002 >From now on, let's meet on Saturdays instead of Tuesdays, like we discussed.
This F=E
delivery agent flag is rarely needed, and
is only routinely included with the *file*
delivery agent. Usually, the program specified by the
local
delivery agent definition handles
From
line conversions. This delivery agent flag
should be used only with delivery agents that
handle final local delivery.
