  5. Hi Irslan, Sorry for late reply. As i understand you query regarding fake mail. We have Zimbra wiki for this solutions. If you apply this wiki in your production server, even after compromising user password , spammer can not change the from address(email address)while sending email because you already enforced from and user id. Only he can send mail from authenticated user .

    I hope this is your requirement. If need anything else please type your comment below.
