This sounds like you need to look at the mail server logs and find the
local addresses for which you have accepted mail. That may not be
completely perfect, but equally looking at the to address might not
help because really you need the envelope-to: address that the SMTP
server used to pass it on, not what is written in the To: header of the
email. Some mail might have both, but I doubt it will be all.
