    Hi all,

    I've a ISPconfig 2.2.40 running well since a long time.

    One of my customer reports a problem when his Autoresponder is activated.
    Sometimes the autoresponder message isn't delivered to the person who is mailing him.

    Example : if toto@orange.fr want to send a mail to my customer contact@cutomerdomain.fr, the responder doesn't work.
    contact@cutomerdomain.fr receives a mail like this :
    It seems that the Orange server want to verify the sender of the mail, and cannot.

    I imagine that this is because the X-Postfix-Sender isn't ok.
    Maybe it expect it to be "contact@cutomerdomain.fr" instead of "web48_contact@isp.mydomain.fr"

    Do you think it is for this reason that it fails?
    If so, how can I correct "web48_contact@isp.mydomain.fr" in "contact@cutomerdomain.fr" ?

    Thank you for your help.

    I've spend some time to try to solve this but I'm not familiar enough with this.

    Could someone give me a little help please ?
