Got a Postfix-Dovecot-Saslauthd setup on Ubuntu 10.04.

Problem is there's (at least) one domain that it refuses to accept emails from. I've been getting emails fine from lots of different domains except one. It's really weird, but could some config file or something be blocking certain domains? or IPs? or something? I know the emails are being sent to me, infact I sent a test one myself from this domain and they're just not showing up.
