postfix main.cf has a "killer" line

[Michael Hipp]

/etc/postfix/main.cf has a line that is a troublemaker and needs to be moved to
a more appropriate spot. Toward the top there is this:

   # Uncomment the next line to use procmail for delivery
   #mailbox_command = procmail -a "$EXTENSION"

But if you uncomment that line it doesn't work because toward the bottom there
is this line:

   mailbox_command =

Which cancels out anything done with the first line. (i.e. it's a "killer" line)

Possible solution: move the second line nearer the first line so the whole
section looks something like this:

   # This causes postfix to do the delivery directly with no help from procmail or
   # other delivery agent
   mailbox_command =
   # Uncomment the next line to use procmail for delivery
   #mailbox_command = procmail -a "$EXTENSION"

(Side note: might also want to add '-t' to the procmail line as it causes it to
fail more gracefully.)

My unmodified main.cf file

The unmodified main.cf that comes with postfix (Warty) for reference.

postfix 2.1.5-6ubuntu1 will not add the 'mailbox_command = ' line on installs.
Not much that can be done to existing machines without either asking questions
or violating policy, however.

Sounds like it is fixed for new versions. Thank you. Marking as FIXED.
