Junk mail, or so-called spam, is from April 1st 2004 illegal in Sweden. Despite this a lot of spam comes from countries where it is still legal. As a government institution we must accept and handle all inbound e-mail. We cannot simply delete inbound e-mail before we have established that it does not require any action.
We have an application, SpamAssassin that marks incoming mail that is thought to be spam. The program analyses incoming e-mail and judges each message after a number of criteria and awards the message a number of points. If the result reaches a certain point limit the message is marked as spam and the text !!SPAM!! is added to the subject line.
You can create a rule in your email client that moves all emails marked with !!SPAM!! in the subject line to a special folder.
Blocking of blacklisted IP addresses
The university has, with start 14 april 2004, begun blocking e-mails that come from blacklisted IP addresses. As a basis for blacklisting of IP addresses the University uses details from spamcop.net that collect information from Internet Service Providers (ISPs) and users worldwide. When spamcop.net has identified a spam source the IP address is blacklisted for up to 48 hours after the spam activity has ceased.
E-mail is blocked with the following message: “Denied because xxx.xxx.xxx.xxx is listed at bl.spamcop.net (Blocked - see http://www.spamcop.net/bl.shtml?xxx.xxx.xxx.xxx). Use firstname.lastname@example.org to pass.”
The link leads to information concerning why the address is blocked. The clerks address is always open regardless of whether the sender’s e-mail server is blacklisted or not. A blocked sender should firstly contact their ISP/e-mail provider and make them aware that the address is blocked.
