XServe Postfix: How can I disable hostname verification so that mobile users can send mail successfully through my server?

One of our mail users cannot send messages through our server from her BlackJack phone. Checking the SMTP logs, I see lots of this:
Oct 2 18:15:11 rammserve postfix/smtpd: warning: 220.127.116.11: hostname mobile-032-161-215-131.mycingular.net verification failed: Host not found
Googling indicates that this is because the hostname has no PTR record. Nothing I can do about that, so I'm looking to disable this check. It's apparently due to the reject_unknown_client_hostname
configuration directive, and/or something in smtpd_helo_restrictions
However, I can't find where any of this stuff is enabled on the server. It's a default configuration XServe. I've looked over the output from postconf -d
, but can't find anything that's causing this warning. Where else should I look? Is this even the problem? If not, what else?
