Well, according to my quick test, using the "dig" tool, that domain
doesn't exist.  Though, a whois check shows that it does.  So, somewhere
there's a problem with your public domain records.  The dig tool might
help you sort out where (you can query different DNS servers with it).

 dig redfish-solutions.com
gets no answer

But this does:
 dig redfish-solutions.com MX


-- 
[tim localhost ~]$ uname -r
2.6.27.25-78.2.56.fc9.i686

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
