V8.8

Prior to V8.8 sendmail , this F=L delivery agent flag caused sendmail to split output lines in the message body so that they did not exceed 990 characters , and always caused sendmail to clear the most significant bit of the characters in those lines.

Beginning with V8.8 sendmail , F=L emulates this old behavior under certain conditions. F=L causes sendmail to assign L= a default value of 990, if it is missing one (L=), and (if the configuration file level is 1 or less) to set the F=7 delivery agent flag.
