About that uucp SMART_HOST line again, try using the uucp-dom mailer rather than the std. uucp mailer. It uses the smtp mailer rules for rewriting envelope addresses. Aside from that, youd have to show uucico logs for both sides to make sure the mail was still addressed correctly on the server side.
