A bad idea for those of us who run *nix systems. Nothing wrong from a
Windows POV and from a X.500 schema POV, which is what the original
mail subscriber seems to be complaining about..

The only invalid character would be a @, which acts as a separator and
hence has to be unique.
By convention, %, + and/or - have acquired special meanings to various
pieces of software, and therefore should not be used.
The / has no such restriction. Mailman has a problem in that it *has*
to remove shell metacharacters and / for system security (given that
the list is being passed to a program). 
Maybe David can find the whitelist of characters in mailman and add the
/ to those to solve his problem. This remains a bad idea, however, from
a security POV.
