I make a mail application by using php, its for the mass mailing program my company have large amount of his member's email IDs. 780000 and more.
by his own forum but somebody put fake IDs like, firstname.lastname@example.org or so on.
there is no domain, no mail ID even I think no person who get the mail
my question is how we diagnose, either ID is original or not. because I send many mail in a single time how the program understand it. how I remove that from a nasty long list?
Suggest me plz.
