Hello, I'm very new to linux only 5 months in.. I was a hardcore windows user but it's just too dam unstable lol anyways.

I setup postfix and cyrus-imap. I can sendmail to anyone but when they send mail to me it doesn't always work.. i did tail -f /var/log/maillog &
too look at what happening this is what i get.

Jul 25 03:04:27 ns1 postfix/smtpd[31737]: A3A2C29C488: reject: RCPT from outmail-01.pclght11.com[66.109.24.73]: 554 <bug@roffle.com>: Relay access denied; from=<1-537067-roffle.com?bug@stderr.pclght11.com> to=<bug@roffle.com> proto=SMTP helo=<outmail-01.pclght11.com>

Why is my server rejecting Relay Access? If there's any config's files you need to check i can post them.. Thanks

If it would not DENY relaying it would be an open relay. You need to adjust your postfix settings. Depending upon your wishes, etc you should make changes to the section "mydestination".

Relaying (IP address based) is set up in mynetworks.
