Well I think that you have done the right thing here. I would also talk to him about this and make sure that he understands how you feel. Once you have done that and you know for a fact that he no longer wants to talk to her, then I suggest that either you or him writes her an email back telling her to go "sniff" around some place else. The last thing the 2 of you need is someone else causing unnecessary trouble.
