======Mail======
Everything associated with mail has High rating as we are dealing with private and restricted data. So no one else then the owner of the mail should have access. Therefore, mail is secured through the user authentication and authorization measures of the OS user account system. For the secure protocol ''%%imaps%%'' is used. For WEBmail ''%%https%%'' is in place.

There are two storage elements to the mail system: Inbox and personal folders. The Inbox is physically located at the mail server to which no user has login rights. Inbox content can only be accessed after successful authentication. The personal mail folder structure resides inside the user home directory space. Both are accessed using the ''%%dovecot%%'' or ''%%MS Exchange%%'' utility (based on imaps encrypted and authenticated protocol).

Sending mail is performed using the ''%%submission%%'' protocol which is both secure encrypted and authenticated.

See [[:email|here]] how to setup the mail client or access [[:webmail|WEBmail]].

====Spam and viruses===
On the mail servers both spam and virus rshielding software is run. For SPAM the spamassassin utility is used and files are marked with a SPAM rating on which the user can filter. Viruses are shielded using the amavis utility where virus detected email is put into quarantined area.
