The mailbox name is valid (it's been munged > here to protect against spam address harvesters). 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.
