I have a user subscribed to my list as:

        [log in to unmask]

From what I can see on theweb interface the name and address in the list
are completely normal.

However, I just got this error (usually there are no errors for this list
member):

  1 09/24 09/24 [log in to unmask]
                Last error: SMTP; 553
                            <[log in to unmask]@DOMAIN.COM>...
                            No such user

The server seems to be jumbling around the name and domain in very weird
combinations.  Is it really possible to misconfigure a mail server badly
enough to do something like this (I'm trying to imagine how ...).
