An antispam and antivirus filtering software is installed on the mail server. Every incoming mail messages is analyzed.
The filter places automatically in quarantine any suspect messages. You are allowed to see and, if needed, to recover your quarantined messages for a limited period (14 days, unless a different range has been set). After that interval, the quarantined mail are automatically deleted.
A web interface makes you able to access your quarantine and to change some settings related to the antispam and antivirus filters.
In particular, please notice that you may require the filtering system to send to you daily a digest of the messages placed in quarantine. This makes you aware of the quarantined messages without connecting to the web interface every day.
