Maybe you can be a bit more specific?
If I understand you correctly, you have emails from only two persons in 
your pop-mailbox.
What you want to do is, to scan through your pop-mailbox and only 
download the mails from user A but leave the messages from user B 
untouched??
If this is what you want to do, I'm not sure if fetchmail can help you - 
I at least have not stumbled over such an option yet.

fetchmail only download my domain mail.
 
Like in my pop a/c two sender mails are there:-
 
From: user(_at_)example(_dot_)com <mailto:From:%20user(_at_)example(_dot_)com>
From: user(_at_)yahoo(_dot_)com <mailto:From:%20user(_at_)yahoo(_dot_)com>
 
fetchmail only download user(_at_)example(_dot_)com <mailto:user(_at_)example(_dot_)com> 
mail, & user(_at_)yahoo(_dot_)com <mailto:user(_at_)yahoo(_dot_)com> mail just keep on 
net(keep on my pp a/c).
 
Like i want "From:" filtering ...
