10.4 Spam

Spam messages are mostly represented by advertisements. Spam are usually sent in bulk and

the recipient addresses are obtained by illegal means (e.g. by tapping the network communi-

cation). In their wilder modifications, spams may also distribute and seed dangerous viruses.

Kerio MailServer contains a sophisticated antispam filter. The filter is designed so that it

can recognize specific attributes of spam from the message contents (spam messages usually

contain specific keywords that can be recognized and counted by the filter). Each message is

assigned a numeric score; if this value exceeds the limit set in Kerio MailServer, the message

is marked as spam.

The spam filter may let some spam messages through from time to time by mistake (their

score is low) and mark some regular messages as spam (their score is too high). For the

reasons above, the antispam filter allows modification to the database used for recognition

of spam messages. This method, however, requires user input. Users have to reassign the

incorrectly evaluated messages to correct types (spam / non-spam) so that the filter learns to

recognize them in the future.

Messages which were marked incorrectly can be re-evaluated by moving them in corresponding

folders. To be specific, to mark a message as spam, move it to the Junk E-mail folder. To mark

a message as not spam, move it to Inbox.

Note: In MS Entourage, messages marked as spam are also marked by specific visual signs.

For example, the line representing the message has a different colour (grey). However, these

methods of spam-marking are not applied to messages moved manually. Such messages are

distinguished as spam or not spam correctly by the server, but they are not changed visually.

This implies that messages marked as spam are still displayed as spam and also displaying of

messages marked as non-spam is not changed by moving them in the Junk E-mail folder.

10.5 Delegating folders and their connection in MS Entourage 2004

Delegating is similar to sharing which allows for assigning access rights (reading, writing,

administration) for selected folders to any user of the same domain. These two types differ in

method of their connection. In case of sharing, user has to connect folder by folder, whereas

in case of delegation, user connects the entire account where he/she can see only folders

enabled by appropriate rights. The main advantage of delegation is more transparent viewing

of connected folders, especially when one user delegates multiple folders for another users.

The following folder types can be delegated:

email

calendars

contacts

email, calendar and contact public folders
