I see this quite a bit...and LISTSERV doesn't like it either.  The problem
can also cause difficulties for the user when they try to send a command via
email.  If [log in to unmask] tries to issue a command for his subscription
[log in to unmask] LISTSERV won't allow it because they don't match.

It's best to not alter the portion of the address to the *left* of the '@'
symbol at all (anything to the *right* of the '@' is case-insensitive so
that's not a problem).  If you use any sort of web form that requires a user
to manually enter their email address this sort of thing may creep in.  The
absolute best way to get a subscribed address correct is to have the user
send it in via email and let LISTSERV parse the address itself.  Maybe try a
mailto: hyperlink that will launch a user's default client.
