>Description:
Any operation involving this port on 10+ gives the following message: 

make: "/usr/ports/mail/postfix/Makefile" line 93: warning: Couldn't read shell's output for "/usr/bin/grep -m 1 '^purgestat' /etc/mail/mailer.conf || true"

This message also appears for all the other postfix ports. It's due to the way bmake treats
empty shell command results.

It's pretty easy to fix though: change "true" at the end to "${ECHO_CMD}".

>How-To-Repeat:
	
>Fix:

The attached patch fixes it for mail/postfix, but it'll also apply for all the other
postfix ports.
