Ive been using php mail function for some time now.
when using mail function the programmer can specify who will receive and send the email even though he is not the owner of the email account.
Some person will use email of firstname.lastname@example.org to send emails to his various subordinates even if this person is not the real owner of this email, using mail function of php… This is frud…
Does any 1 know how to filter this out to avoid people who are not owners of emails to send out emails and to protect email account owners.
Any help woud be greatly appreciated.
