PHP邮件功能未发送

Question

For some reason, my PHP mail is not sending.

This is my script:

$tom = $email;
$subjm = 'Company: Forgotten password';
$msgm = "-- DO NOT REPLY TO THIS EMAIL --\nHi,\nYou have forgotten your password.\nHereby we want to supply a you a new one.\nNew password: $pass";
$msgm = wordwrap($msgm, 70);
$mail_sent = @mail($tom, $subjm, $msgm);
echo "$tom <br /> $subjm <br /> $msgm";
echo $mail_sent ? "Mail sent" : "Mail failed";
echo "<br />Your new password has been sent to the email you've signed up with.<br />If you can't find the email, please wait a few minutes or check your spam box.";

However, it always gives me "Mail failed", and I do not see it in mailbox. I've checked if the correct emailadress was being produced by my script ( $email ), and it was. So I'm kinda lost as to why it will not send.

Answer 1

You need to supply a from address in order to conform to RFC. Also the return value of mail does not tell you if the mail was sent or not. It does only tell you if the underlying mail server accepted the mail.

For a more elegant way to send mail not only using your local sendmail but by any SMTP server have a look at phpmailer .

Answer 2

As a follow up to the comments, I contacted my webhost. They tell me I can't send emails using the mail function to recipients that are not on the domain. I'm resolving the issue with them.

Edit:

I needed to add a From:, and the emailadress of From should be a @mydomain.com address, not external. It works now.
