It's not quite as simple as that.  There are now two formats of
Compuserve email addresses.  The old style user-id format
(octal.octal@compuserve.com) remains valid.  However there is now the
new style alphanumeric_alias@compuserve.com, designed to give Compuserve
users more normal looking email addresses.  I forget the exact
restrictions, but there is no reason why 8s and 9s shouldn't be present.
What you need to reject (according to most of the forged Compuserve
addresses I see) are a number or a dotted pair of numbers that contain
an 8 or a 9.
