This indicates that the message is rejected by content filter.
I belive due to some words it is blocked.

Send a simple test mail and check.

What I often do is take the domain that is being rejected and check it against the blacklist on MXToolBox. Often you'll see that they are on a blacklist or have a DNS issue, report this back to the sender.

Or, you may have the content filter adjusted to tight. Click here for a good understanding how it works.

Thank you WORKS2011

We are using Untangle to filter spam so I have now disabled spam filtering in SBS. I'm sure it will solve my problem...
