If they are using your server they must already know the login. Check your server logs.

Are you confusing Return Path with Return address? If they're using your server to send email they're using your server as the Return Path.

If you don't want them to send outgoing email throughyour sever while having (for example) a yahoo email address set as their return address, then you'll need to catch it with custom-code in exim.pl, and scan every outgoing message. And you'll need to decide what to do with the emails you don't deliver, since yoou can't abandon it, and you don't want to send it to yahoo since the sender email address may be spoofed.
