Service unavailable: Bad file number I saw the very same symptoms Thursday of last week on one of our systems. Turned out that the system thought its hostname was "zippy" but it was listed in the host table as having an entirely different canonical name, with "zippy" as an alias. I just changed the hostname of the machine to the canonical name listed in the host table and everything was kosher. Alternatively, changing the host table submission should work equally well, but might take time to propagate. If you're running named, you might check any cname records for iemisi.dhc and make sure the canonical name is, in fact, the same name iemisi.dhc thinks it is. Oh, and you should probably restart the mailer after you're done, so it'll recheck the hostname. Let me know if this works.
