Not really. Large mail system like Gmail and Yahoo have a pretty good map of the IPv4 address space. If you're sending from a residential DSL or cable modem range, they'll likely reject any mail you send directly no matter what you do.
Which is why I finally gave up and speak to an 800 pound gorilla on port 587, because nobody dares to mess with that gorilla's port 587 so my laptop can always get mail sent. :)
