When testing postfix2.10 against my master.cf and main.cf, it throws up a complaint about this line:
procmail unix - n n - - pipe -o flags=uhFORD
user=vpopmail argv=/usr/local/bin/procmail -t -m USER=${recipient}
EXTENSION=${extension} /usr/local/etc/procmailrc.common
which I've been using for years to enable procmail processing on my mysql users.
all of uhFORD are defined in http://www.postfix.org/pipe.8.html
