Sorry, when it tries to send the mail out, it tries to send it to coker.com dns record which is 126.96.36.199. For some reason it is not seeing the MX record which is 188.8.131.52 (mail.coker.com).
We do get email from other sources just fine, but for some reason our box isn't looking at the MX record but instead trying to communicate with 184.108.40.206 which is not a mail server and therefor giving the connection error.
I'm really at wits end here...I've searched these forums and the internet for days now and can not find this problem any where.
