PHPMailer，无法发送某些电子邮件

Question

Our company sends out emails through phpmailer to our customers and certain emails never go through to certain people... (emails for .gov, .amec, and others)

If we use the same email address and send them the exact same email in outlook they receive it just fine. Does anyone know whats the issue is? I've been told it could be the headers, but I'm not to familiar with how to solve that.

Here is our mailer code:

Note all variables/non-logic has been replaced with {{}} for this example.

    $mail = new PHPMailer();
    $mail->IsMail();
    $mail->SetFrom({{from address}}, {{from name}});
    $mail->AddAddress({{address addition}});
    $mail->WordWrap = 70;
    $mail->IsHTML(true);
    $mail->Subject = {{subject}};
    $mail->Body = {{body}};
    $mail ->AltBody = {{alt body}};
    $mail->MsgHTML({{msg}});
    $mail->Send();

Answer 1

Change $mail->IsMail(); to $mail->IsSendmail();

Also, if you change $mail = new PHPMailer(); to $mail = new PHPMailer(true);, it will throw exceptions on errors.

Third, you don't need $mail->MsgHTML({{msg}}); line - just put all of your message in the $mail->Body = {{body}};.

Your code should look like this:

$mail = new PHPMailer(true);
$mail->IsSendmail();
$mail->SetFrom('[e-mail]', 'MyFirst MyLast');
$mail->AddAddress('[e-mail]', 'First Last');
$mail->WordWrap = 70;
$mail->IsHTML(true);
$mail->Subject = 'Example Subject';
$mail->Body = $body; // can set using ob_start(); and ob_get_contents();
$mail ->AltBody = 'Alt body message';
$mail->Send();

• Footnote: Some servers/email clients will block out emails with certain headers, domains, etc. - there's really no way to check all of the variables because no matter what, someone will at some point not be getting every email that you send out. Tools like MXToolbox can help you sort through some issues.
