they are directed to random generated username. Definitely not from
within my server but if it is, i have no way of check as the mail i
received cannot be traced the sender. IP is from random servers.

Yes, i want the technique to only accept valid mails without going
through Mailscanner as what is happening now and what i have already
tried.
