We are having trouble sending mail to an entire domain, and coincidentally, that domain is unable to send us mail.
Our mail server is hosted with GoDaddy.com (who uses a mail server at secureserver.net). Our domain name is mcgrailgroup.com.
The intended recipient domain is ccil.org. I have masked the sender and recipient addresses for privacy reasons.
When I send an email from mcgrailgroup.com to ccil.org, I get the following bounceback:
Hi. This is the qmail-send program at smtpout03-04.mesa1.secures
erver.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Giving up on 192.190.237.100.
When I send an email from ccil.org to mcgrailgroup.com, I get the following bounceback:
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
private@mcgrailgroup.com

I know GoDaddy does extensive spam filtering, but this is unexplainable as far as I can figure that both sender and receiver would get the same error messages.
