Guessing someone's email address programmatically is utterly
impossible. [1] The only solution is to add a config variable where the
user specifies his address; if you don't have it, you can't use your
special code.

[1] OK, OK, I thought of an idea: send a message to a special cooked
address that you (the programmer) control; for SA, it might be
"[EMAIL PROTECTED]". A script behind this address
would record everything it can think of about this incoming message,
most importantly the SMTP and header sender addresses. Your program
would wait five or ten minutes, so there's a reasonably good chance
the test message has been received, and then query spamassassin.org
(or whatever) through some other protocol. Hell, make the database
of received email addresses accessible through a CGI script and make
it HTTP. The database then says what the address of the current
user is.
While writing this completely crazy idea up, I've already thought of
three of four reasons why it can't possibly work. Oh well.
