PHPMailer : replace the default messageID

I send emails using PHPMailer, evthg works well but I would to set a uniq MessageID for each email.

PHPMailer version : "v5.2.16"

(loaded with Composer from https://github.com/PHPMailer/PHPMailer.git)

I found the documentation here : http://phpmailer.github.io/PHPMailer/classes/PHPMailer.html#property_MessageID

so here is what I tried :

 $mail = new PHPMailer;
 ...
 $mail->MessageID = md5('HELLO'.(idate("U")-1000000000).uniqid()).'-'.$type.'-'.$id.'@domain.com';

Result : This is always the default MessageID generated by PHPMailer :

enter image description here

and not mine... :(

Then I tried sthg more simple :

 $mail->MessageID = "[email protected]";

Result : KO (the same)

The documentation indicates that we can set a MessageID, and it should be a string, I don't understand at all why it doesn't work...

Any idea ?

Solution

  • The structure of MessageID should be:

    <sometext@sometext>

    If your MessageID doesn't have this exact structure - PHPMailer will ignore your MessageId and generate it's own MessageId.

    You can change your code to:

    $mail->MessageID = "<" . md5('HELLO'.(idate("U")-1000000000).uniqid()).'-'.$type.'-'.$id.'@domain.com>';

    And it should work.
