We have recently configured a mail server with snow leopard 10.6.
The mail server seems to work properly, it receives messages from every domain, but only send them to the local domain.
When we try to see the log, we can only see a relay access denied message.
How can I see a more detailed message? How can I fix this issue (not sending to no local domains)?
If I put access relay host gmail.com the relay access denied message dissapears when sending mails to gmail.com domain but it remains without sending the email to that domain. Any help will be wellcome. Tell me if you need some log files,...

    There is no way on earth this line is correct:

    mynetworks =,essbilbao.net,gmail.com,hotmail.com,essbilbao.com

    This command (in conjunction with the snmpdclientrestrictions tells postfix to accept mail from (localhost), essbilbao.net (, essbilbao.com (, gmail.com ( and hotmail.com (

    NO other IP addresses will be accepted. This includes machines on your local LAN

    The mynetworks setting should contain the IP addresses of your trusted network systems - typically and the LAN addresses of your network (e.g.

    Beyond that you need to look at the mail log (/var/log/mail.log) to look at why messages are getting rejected.

    Thank you very much for the answer.
    We changed it but it still without working.
    /var/log/mail.log doesn't output any information about it. Nothing! How can increase the log level?

    The messages goes to the server (data: (250, '2.0.0 Ok: queued as B587024A7BB')) and we can see them in the Server Admin tool. In this tool the error message is "mail transport unavailable"

    Settings-> Logging. Increase SMTP log level to 'Information'

    Thank you very much. The log was increased.
    Finally we discovered that it was a DNS problem. We reinstalled OSX and works fine.
    Thanks again
