I have a GroupWise 8.0.1 GWIA
It is relaying through another server which is an RedHat Server. Not too sure about the software running on this server. It is used to send encrypted mail concerning patient medical history.I'm getting the following message

Hi. This is the James mail server at SERVER.domainname.fr.
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. Below
I include the list of recipients and the reason why I was unable to deliver
your message.

Failed recipient(s):

Error message:
Broken pipe

I cannot find a lot of information on the Web concerning the broken pipe error
The support for the relay tells me that their server is working perfectly. (Well maybe)
Any help would be greatly appreciated
