In order to improve the services offered to users, the University of Calculus Center of the University of Palermo has made operational a service for the interception of junk mail, called SPAM.

The interception criteria of this type of messages are heuristic and act by examining each message, analysing its characteristics and assigning a score based on the tests carried out (for example if the message contains html code, if it contains coloured text, if the sender sends the message using a server regularly registered in a dns etc...).

If the total score obtained from the message thus analysed exceeds a certain value, the message is classified as SPAM and automatically moved from the messages arrived to the SPAM folder pertaining to the user.

This system, although it has proved to be one of the best to adopt, is not, for obvious reasons infallible (for example, an email message with the word VIAGRA in the subject, can be considered SPAM for most users but could be interesting for a doctor or pharmacist).

For this reason, through the web mail service it is possible for each user to configure the management of their SPAM folder.

To do this, the user, once logged in to the service, must access the user preferences by clicking on the preferences icon or preferences depending on whether the language is Italian or English.

In the upper part of the user preferences page is present, among others, the SpamAssassin configuration icon, SA prefs which, in turn, opens the anti-spam system preferences page.

On this further page, there are two icons:

-The first, blacklist allows you to add to a blacklist unwanted email senders (SPAM) that the system fails to intercept.

If the user has received an unwanted message from someone@something.com and the system has not intercepted it, just someone@something.com in this list.

-The second, whitelist, aims to add to a blank list the senders of email that the system, erroneously, considers unwanted (SPAM).

If the user has received a message from someone@something.com that the system has wrongly classified as unwanted (SPAM), adding the someone@something.com address to this list, all subsequent messages from this address will be regularly delivered in the inbox folder.

By entering an asterisk (*) in the white list, you disable the anti-spam service.

 

The SPAM folder pertaining to the user is visible, in addition to the web mail service, through any email client that is configured for the use of the IMAP or IMAPs protocol.
