PHP mail（）和hotmail

Question

I'm launching a product today and COMPLETELY OUT OF NOWHERE hotmail accounts can't receive email from my php mail() script.

I've searched around and found others with similar problems but haven't found a true solution

$Email = "my@email.com";
$Name = "My name";
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= "From: ". $Name . " <" . $Email . ">\r\n";
$body = "bleh";

mail($recipient, "My email", $body, $headers);

It sends fine to GMail etc just not hotmail.

Anyone conquered a similar problem? It doesn't go into SPAM either

Answer 1

Try to use SMTP instead. Mails from mail() often go to spam folder, because servers can't verify source of message.

Answer 2

Is this the exact code you're using?

A long shot, but could there be a conflict in your e-mail validation (if there is one)? A while ago I had an issue where regex wasn't catching hotmail accounts, took me so long to figure it out.

Else, I agree with other responders that some mail services simply delete what they think is spam, I think there's a "spam level" thing where you set how aggressive the spambot is.

Hope this helps.
