mail() delivery failure

[malumenezes]

Hi, there

I have a webpage where the user can send e-mails. The user types his e-mail address, then the address of the receiver, and the system sends the e-mail.

The problem is:
I can check if the e-mail field is valid, but what if the e-mail is valid but it doesn't exists? Then I must send a failure notice to the person who wrote the e-mail.

How do I check this?

I'm using the mail() function in php4.

Thanks,

IIRC, there is an SMTP "Errors-to:" header that you might be able to include in the fourth parameter to your [man]mail/man call....

I don't know that it would work, but it'd be worth trying...

HTH, 🙂
