How to skip mail() if e-mail's domain doesn't exist?

[nicdp]

I noticed that the mail() function doesn't work trying to send it to an e-mail address with a domain which does not exist.

1) IS THAT NORMAL?

I mean: instead of simply getting back an error message the page on which the script takes places won't be loaded.

2) HOW CAN I WRITE A SCRIPT WHICH SKIPS MAIL() IF THERE IS A PROBLEM SENDING IT?

If possible it would be great to get back a message like: "problem sending e-mail"

Simple if statement. mail returns false on failure.

if(mail($to, $subject, $body, $headers)) {
   // okay
}
else {
   // it failed
}

if you're doing for a single email, using if(mail(...)) works great. If you area doing multiple (50 or more) emails, I would not recommend using mail. On many server's it's very slow. Instead send directly through the smtp server (php can do this), and check the domain by doing an HTTP head request like in example 2 on this page: http://www.phpbuilder.com/manual/ref.sockets.php (doesn't look fun, but not impossible, and probably pretty fast - if your server isn't bogged down).

Are you sure? I thought mail returned true if it passed the parameters on to the mail exe without errors, not that the mail was sent sucessfully.

Returns true if mail was successfully accepted by the mta for delivery. In this case, it sounds like it's not being accepted, so this solution would work.

It doesn't work. What is weird is that i tried with 2 different not existing e-mail addresses:
- [e-mail]
- [e-mail]

No problems with the .org one (click here )... but with the .it one...look what happens:
click here

The script is te next:

<?php
/* subject */
$subject = "TEST";

/* To send HTML mail, you can set the Content-type header. */
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

/* additional headers */
$headers = "From: PINCOPALLA <[e-mail]>\r\n";
$message = "TEST";

/* and now mail it */
if(mail('[e-mail]', $subject, $message, $headers)) {
   echo "OK";
}
else {
 echo "NO";
}

echo "CIAO";
?>
