Your relay says that there is a temporary local problem on your relay. 
First place to look is into the mail logs on your relay and find out 
what problem it is. Until you know the problem it's pretty pointless to 
guess what it might be and what might fix the problem.

You should know what your mail relay needs to process the email. So you 
should know what you need to set.

So find out what the problem is on your mail relay and then you most 
likely know what's wrong or missing. Then you have to either fix your 
relay or spacewalk or both, depending on what it is...
