Perhaps someone isn't looking for an unknown IP-address, but just want
to prove that the owner if a given IP-address is the owner of the
Mailbox "green lantern at yahoo".
If this one is able to do a traffic analysis on this IP-address and
knows the login time at the pop/imap-Server of yahoo, a well defined
pattern of mail sizes could help.
But in this case I think it's not useful for him, to send these mails in
such short intervals, because you would fetch both mails at one login
and in one stream of data...
