Fetchmail fetchs mails and resends them through you local MTA (so it always uses 127.0.0.1). To filter by the sender IP, your MTA has to be the [unique] MX of your domain...
Postfix actually has a feature (XCLIENT) to receive this information to the software connecting to it: http://www.postfix.org/XCLIENT_README.html
However, AFAIK, fetchmail does not have support for it, and I'm not aware of any patch that uses it.
