                        ^^
do you mean to have a + here instead?

May 27 11:00:02 eth0 postfix/pipe[25377]: DCA7868417:
to=<phil+howard at example.com>, relay=dovecot, delay=0.27,
delays=0.21/0.01/0/0.05, dsn=4.1.1, status=SOFTBOUNCE (user unknown)


the errors in your other email suggest (to me, I could be way off base)
that postfix isn't finding <phil+howard at example.com> as a local
recipient. This might have to do with the delimiter though.
