如果发件人是Yahoo邮件，则Gmail不会收到phpmailer电子邮件

Question

I'm trying to figure out why Gmail doesn't receive emails if the $mail->From ="" is set with a yahoo account.

        $mail = new PHPMailer();
        $mail->IsHTML(true);
        $mail->From = "$email"; 
        $mail->FromName = $name;
        $mail->AddAddress($admin_email);

Above is a part of my code.

Answer 1

It's not really supposed to work.

Among other things, GMail likely checks the Sender Policy Framework (SPF) for the sender domain to see whether your mail server is allowed to send from that domain. It's unlikely that Yahoo allows this kind of address spoofing from any server, therefore you fail the basic SPF check.

What I would do in your situation is set a static mail from address, but a dynamic reply-to address.
