Re: Underscores in host names

In article <Pine.LNX.4.60.0505180849230.24969@hermes-1.csi.cam.ac.uk> you write:

There are also mail domains to consider. They have superficially the same syntax as host names (they cannot have a trailing dot) but they are generally checked much more strictly for conformance to that syntax. I'm not sure whether the original post was about a mail domain or the name of a mail host, but if it was the former I would be surprised if the customer could claim that it works most of the time.

Hostnames can't have a dot at the end either. The dot at the end is a local resolver indication to not use the search list. Mark
