where to send web errors?

[Pat Fitzgerald <fitz @ sware . com>]

I'm the author of the MailServ (http://iquest.com/~fitz/www/mailserv)
web interface.  I recently stopped using an "Errors-to" header, and
now use sendmail to set the envelope return address.  My question is:
where should I send the error messages?

I currently send the error messages to a built-in address (my own
address) or to an "errors" address that can be specified as a hidden
variable in the form.

However, ListProcessor v6.0 uses the envelope return address as the
subscription address.  So when a user tried to subscribe to a
ListProcessor list, it subscribed me instead.

I could instead set the envelope return address to the
subscriber's address, but what would happen if the user mistyped his
address?

Any opinions as to what I should do?

p.s. I know that ListProc 6.0 has a patch to use the "From:" header
instead, but that is not always under my control.
