Dear HuaMinChen,
 
  can you please explain the reason why you want to achieve this?

Hi Elite,
To share with more people, that the current has registered to one popular site. Thanks

I think you will be able to get this information only if you ask that "popular site" if they want to give you access to such a listing...
and I doubt you can get that access, without the email owner's permission, such access.
also, a "listing" of all email addresses an email was ever send to is not maintained in any emailing server platform, only the emails that are still there could be listed, extracting the email addresses from there ...
listening ...

Yes, after having got the permission from the relevant user, the process will further retrieve the email address list of the user.

Any help?

and how would that "permission" be granted?
I mean, it would be the popular site that would be aware of the permssion, given by the user.
so, are you in contact with that popular site / yahoo about this?
if they have such an interface, they shall help/guide you on this, experts-exchange will not be able to help on this one, as the first steps are to be done between you and that site: you need to define a interface for this process.
without this, we cannot give any "code", as we don't have such access/api

I need the sample interface to "talk" with Yahoo, for listing out the list, per the confirmation of the current user.

then, I repeat, you have to talk yahoo.

Is there any specific Yahoo support mail address to ask for this?
Do you think I can get my expected thing in Yahoo forum?

Do you think we have to separately approach the relevant party, per the relevant Free email  address involved, like hotmail, gmail and etc?

yes, as each party may (or may not) have different API.
there is no unique interface for such things. what IS unique is the SMTP/POP3 protocols to send and read emails.

Thanks. Do you think I should ask hotmail and Gmail respectively, for the ways, to retrieve the list, right?

yes, exactly

Where is the place to ask for anything regarding Hotmail? thanks a lot
