Its possible. However its a really really bad idea.
You can do this using an acl which accepts if the sender address is
right. However this does basically make you an open relay - and people
will find out how to relay through the box.

Why can they not use authenticated SMTP - even MS clients can do that
now? You really need to move to an authenticated SMTP based relaying
for anything not on a local controlled network.
