We are using MDaemon Professional Edition.
Issue is: I have an account email@example.com. I send newsletters with this account to our members. I am sending about 20K to 60K mail copies each day. So, some users' mail accounts are over quota, or some users are insisting to reply to that mail address. And also I am recieveing MAIL CANNOT BE DELIVERED, PERMAMNENT ERROR messeges continiously. I have checked THIS ACCOUNT CANNOT RECIEVE MAIL FROM OUTSIDE world. Yes, it is not recieving mails from outside world. But it is refusing and sending mail to senders like, no such account is present etc.. And mail server (local account) is sending to that account thousand of mail cannot be sent messeges. I want to delte right away anykind of mail addresses to firstname.lastname@example.org
Thanks in advance.
