Postfix Relay Access Denied

I hace installed
Postfix in ubuntu server 8.10 in a dell poweregde 2850

The mail server is in the local netowork behind a cisco router

I can log into the mail server successfully using Ms Office Outlook 2003 and RoundCube web client

I can send emails to domains like google, yahoo, etc but the server rejects mails from the otherdomains and itself.

The error message is like
"Mar 30 12:31:46 mail postfix/smtpd[6445]: NOQUEUE: reject: RCPT from rv-out-0708.google.com[209.85.198.248]: 554 5.7.1 <administrator@kec.or.tz>: Relay access denied; from=<chanangae@gmail.com> to=<administrator@kec.or.tz> proto=ESMTP helo=<rv-out-0708.google.com>
Mar 30 12:31:48 mail postfix/smtpd[6445]: disconnect from rv-out-0708.google.com[209.85.198.248]
".

I have a redhat enterprise 3 using sendmail works fine inside out

can any one help

It appears your server does not see itself as a destination for the email it's receiving. .

I would verify the following items to start.

Code:



mydomain = somedomain.com

myhostname = mail.somedomain.com

mydestination = $myhostname, localhost.$mydomain,mail.$mydomain,$mydomain

mynetworks = 212.18.32.32/27 127.0.0.0/8

relay_domains = $mydestination

smtpd_recipient_restrictions = permit_mynetworks,check_relay_domains

post the output of postconf -n for further assistance.
