Track emails sent by SMTP with PHP?

There is no way to track the email once it leaves however you do have two options. One is to check for bounced messages. Normally outgoing messages will specify a return-path that the bounces will go to.

Unfortunately there is no way to 'track' email once the SMTP server has send it to the recipients mailserver.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
