SMTPLINELIM
Default for obsolete F=L flag Don’t change
Each delivery agent that is defined in the
configuration file may or may not have an L= (line length) equate
(L= on page 745). If that
equate is missing, or if the value assigned to it is
less than or equal to zero, and if the F=L delivery agent flag
(F=L on page 775) is set,
the default value that is used becomes the value of
SMTPLINELIM. Otherwise, the default value is 0. This
logic is there to support old configuration files
that use F=L in
place of the newer L=.
The default for SMTPLINELIM is 990 (defined in
RFC821), and that value should not be changed.
Rather, if you need a different line-length limit
for a particular delivery agent, you should use the
L= equate when
defining it.
