All my milters document the F=T and F=R flags concerning
INPUT_MAIL_FILTER() settings. In the early days of milter-sender I even
suggested that F=T be used in the sample.mc configuration. I later
removed it for reasons that others have mentioned already (I think its
even mentioned in the 0.x change logs some place).
I'm at a loss for adequate words of thanks for the vote of confidence so
many of you express about my work. But please remember the early days of
milter-sender or milter-spamc or any other milter I've written to date.
They are not always perfect from day one and sometimes when I make grand
sweeping revisions I still make mistakes, even after almost four years
of milter development and many many more years as a C programmer.
Mail is important to all of us and spam/viruses our bane. As postmasters
we walk a fine line choosing and implementing policy on behalf of our
users that we hope is the best for all. My milters offer a wide variety
of strategies and choices, but
no one milter is so important that mail should be
held up or refused in the event that a milter fails.
I do NOT recommend the use of F=T or F=R. Its far to easy to shoot
yourself in both feet. There are too many possible points of failure,
most of them human caused, to account for.
