    Hi,

    I try to send newsletter and I notice there are always considered as spam.

    So I decided to use this service to check what is wrong : https://www.mail-tester.com

    Except the fact of our server is not totaly well configured for sending mail, there is a penality about message ID :

    -1.167 INVALID_MSGID Message-Id is not valid, according to RFC 2822
    -3.199 MSGID_NOFQDN1 Message-ID with no domain name

    Can you double check how you make the mail header because I have no issue with other newsletter/mailer system on the same server.

    Ok, so you may change lettreinfo.php on line 1981 from:
    $headers .= “Message-ID: <“.$nl_id.”@”.$prov.”>”.$this->eol;

    to
    $headers .= “Message-ID: <“.$nl_id.”.”.time().”@”.$prov.”>”.$this->eol;

    Like that you keep post id in the mail header and you have a timestamp to retrieve when it was send. Then you are sure that message id is unique cause of time stamp and is not too long or too short.
