Postfix errors sending and such

[ledoktre]

Greetings;

I am hoping to leave a message on here in hopes someone will see this and know right off what to look at :-)

My Postfix, which I know was working fine, broke somehow, in my quest to setup SSL.

Whenever I try to send a message out, whether through webmail, or through Thunderbird, it fails, saying :

An error occurred while sending mail. The mail server responded: 4.1.2 <someone@somedomain.com>: Recipient address rejected: Domain not found. Please check the message recipients and try again.

I can send from shell, but it sits in mailq, and will not go out (with the same error). Sending from webmail or Thunderbird yield an instant error.

I have disabled the TLS part with # marks, and restarted postfix, but yet to no avail. Where's a good place to start troubleshooting this ?

Thanks,
