    For a week I can not send emails from Outlook or thunderbird.
    On webmail everything works fine.
    On Outlook :

    Code:
    Une erreur est survenue lors de l’envoi du courrier. Le serveur de courrier a répondu : Please turn on SMTP Authentication in your mail client.
    (MacBook-Pro-Joee.local) [41.200.xx/xx]:55647 is not permitted to
    relay through this server without authentication.. Veuillez vérifier l’adresse du destinataire emailofcontact@gmail.com et essayer à nouveau.
    ON Thunderbird i have this error :

    Code:
    Certains des destinataires ou tous les destinataires n'ont pas reçu votre message.
    Impossible de contacter le(s) destinataire(s) suivant(s) :
    Erreur serveur : '550 Phpnet - relai interdit - authentifiez-vous'
    How to resolve this problem ?
    Merci.

    Hi @Oualid

    Can you confirm in both clients that SMTP authentication is enabled? In Outlook this is a checkbox next to "My outgoing server requires authentication" For Thunderbird, this is in Account Settings>>Outgoing Server SMTP


    Thank you,
