I'm confused...

If you are talking about *incoming* mail (ie, 'mail accepted for 
delivery', then you are NOT talking about OUTGOING mail.

SMTP AUTH is for OUTGOING mail.

RECIPIENT VALIDATION is for INCOMING mail.

? What is a 'false email setup'?

Oh - you mean 'forged from address'?

Then what you need to implement is recipient validation.

But - not having recipient validation implemented will NOT cause you to 
get on any blacklists, so you *must* be talking about two *different* 
problems.

POP before SMTP is inherently insecure - *please* don't use that. Use 
smtp authentication - preferably with TLS encryption.

No - you just need to do away with pop-b4-smtp and implement smtp auth - 
and possibly fix the misconfigured MTA - maybe it is not set to only 
accept mail for domains for which it is authoritative?

By the way - you really should *not* be experimenting with something you 
don't know how to use on a live server...
