Sending Emails->Checking for Bounce Backs?

[sjaguar13]

I would like to add the option to mass email all the members on my site. I looked into a bulk email program, but they look lame. I have to export my list and then import it. I figured I could just do it all from my site, but the one thing I liked from the programs was the ability to remove addresses where the email bounces back. Is it possible in PHP to check to see if an email went through or came back? Would I have to log into the email account I used as the send from address to see if I got a response or is there another way?

Yes, unless you check the email account you cannot know about the bounce. Best would be to set up an account to catch the bounces.

Most undeliverable emails are not going to bounce because sensible mail servers don't bounce undeliverable emails because 99% of them are spam with fake from addresses.
