    Question Suspicious attack? (Tons of rejected emails)

    Hi all,

    Today when I check on the daily mail report, i found over 27K rejected emails from our server, someone seems to sending emails to account with random name, is there anyway to stop this? Thank you.

    I think you'll find it is quite common! It never ceases to amaze me that many mail 'admins' have never seen what a mail server actually handles on a day to day basis when the get away from a 'point and click' mail server.

    Look thru the logs and you can learn a lot more.
