He would probably be better of posting the unedited output of: 'postconf -n' along with any pertinent log entries, error messages, etc. He probably should just move the entire thread to the Postfix forum anyway. They are really more adept at handling this since it does, at least partially, pertain to Postfix. -- “Gerard” [EMAIL PROTECTED] Mandrell: "You know what I think?"

Montag, what values do you have in /usr/local/etc/postfix/main.cf for mydomain myorigin mydestination mynetworks? What is the FQDN of the machine you are trying to send mail from?

This is happening on your machine because you are using telnet on OS X Leopard: http://chip-miller.net/2008/03/14/solving-a-dns-mystery-on-os-x/ Try telnet from a FreeBSD (or any other) machine, and you will get: # telnet my.mywebsite.com 25 Trying 208.87.33.150... telnet: connect to address 208.87.33.150: Connection refused telnet: Unable to connect to remote host -- Sahil Tandon <[EMAIL PROTECTED]> ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Did you, by any chance, also edit the hostname of the error message? Are you _really_ the owner of `my.mywebsite.com' or is this just something you manually wrote when copying the error? If you manually modified the original error, to hide the domain name, we have to `guess' why the mx1.freebsd.org host fails to resolve your hostname. Please show us the real hostname, and then we may be able to help you more effectively.

Pure conjecture, but I think in trying to avoid exposing his machine's real hostname, he just wrote my.mywebsite.com, which just so happens to be an actual hostname.
