# TV: Leaving this in, because process mail program probably has some
# limitation retained

# this fun line added on 2/5/98. do not remove. Translated to english,
# that's "take any line longer than 1000 characters, and split it into less
# than 1000 char lines.  If any of the resulting lines is
# a dot on a line by itself, replace that with a blank line."
# This is to prevent cases where a <cr>.<cr> occurs in the log file.  Sendmail
# interprets that as the end of the mail, and truncates the log before
# it gets to Tinderbox.  (terry weismann, chris yeh)
#
# This was replaced by a perl 'port' of the above, written by
# preed@netscape.com; good things: no need for system() call, and now it's
# all in perl, so we don't have to do OS checking like before.
