$l (lowercase L)
The Unix From format V8.6 and earlier
Prior to V8.7 sendmail, the
$l macro was
used to define the appearance of the five-character
"From" header,
and the format of the line that was used to separate
one message from another in a file of many mail
messages. This role has been assumed by the UnixFromLine option. See
UnixFromLine on page 1113 for a
description of both this $l macro and that new option.
