I was unclear. Exim has a `cyrus_sasl` authenticator:
http://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_cyrussasl_authenticator.html
That authenticator should be passing the source address in via
`sasl_setprop()` calls.
The saslauthd expansion condition is much more limited.
See the `sasl_plain` example in the documentation page above.
