Hijack detection enables an MDaemon administrator the ability to configure a set number of messages allowed to be submitted by any one account in a defined number of minutes. Authenticated sessions are not exempt from this feature. If an account crosses this threshold the postmaster is notified via email and the option can even be configured to freeze the account. A frozen account can still receive mail. However, the account cannot send mail. This feature is useful to prevent compromised accounts for submitting scores of spam and having domains added to internet black lists or report poor sending reputations.
