I have followed the perfect setup for fedora core 6. I have setup a site and an email address. I have tested telneting to localhost and all test pass. I can connect to webmail and I sent a test messgae to my work email account. It worked just fine. I then sent an email from my work email account to my new email address and I get this in the maillog: Dec 4 17:28:16 kelly postfix/smtpd: NOQUEUE: reject: RCPT from sp-internet-ext-ply.uhc.com[22.214.171.124]: 554 5.7.1 <email@example.com>: Relay access denied; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<firewall-cluster.uhc.com> I have searched the forums and have tried several things but nothing works. I have tried removing the site and recreating. I have redone the postfix stuff from the perfect setup guide. Nothing works. Where can I look now? Thanks.
