What is quarantine?

Quarantine (segregation) of e-mail messages used to be a common method of automatically sorting out harmful and unwanted e-mail messages at the mail server and storing them separately from the mailbox.

The mailbox owner was notified of each new message stored in the quarantine and then had to check this quarantined message in an environment separate from his usual mail software (usually via web interface) and could decide whether to deliver it to his mailbox or not.

This procedure was extremely complicated and not very comfortable for the mailbox owner and email user.

Since SPAM filters can work much better nowadays, modern e-mail providers -like Mailix- do not use quarantine and completely refuse to accept messages with very high SPAM scores, as well as store messages with not so high SPAM scores directly in the mailbox, but in a separate folder for SPAM (junk).
