You mean put MacPorts paths first?  I did that and all was well except the
one thing I needed postfix for.  Namely, sending mail with the 'mail'
executable on the MTA host.  I guess 'mail' isn't part of postfix and
Apple's 'mail' executable must be hardcoded to use /usr/sbin/sendmail
because it would not look at MacPorts' postfix alias file.  So that's why
I had to use the symlink.  It may be most people don't need to send mail
with 'mail' from the MTA host, but some apps need this and it should work
anyway.

I can't find a postfix-watch command.  But I suppose it wouldn't matter
anyway if Apple's LaunchDaemon is removed?

So would it be ok if I modified the ui_msgs from this:

ui_msg "To get postfix working, you need to copy sample configuration "
ui_msg "files and to edit them (${prefix}/etc/postfix/*.sample)."
ui_msg "You may also want to turn your system's MTA off."

to this:

ui_msg "\n
To get postfix working, you need to copy the sample configuration
files and edit them (${prefix}/etc/postfix/*.sample).  You may also
want to turn off Apple's built-in MTA.  For example, on 10.4:

-Delete /System/Library/LaunchDaemons/org.postfix.master.plist
-Replace the built-in sendmail file with a symlink to MacPorts' sendmail:
	sudo mv /usr/sbin/sendmail /usr/sbin/sendmail.org
	ln -s ${prefix}local/sbin/sendmail /usr/sbin/sendmail \n"


I think it will help reduce headaches and questions to the list.
