Filtering mail using CleanMail

Filtering and Routing CleanMail and CleanMail Plus Email Messages

CleanMail and CleanMail Plus are available only to customers using NetNation's Advanced Mail Service. You can upgrade to Advanced Mail Service in AccountManager's Email section.

CleanMail and CleanMail Plus provide spam and virus filtering that helps keep your email span- and virus-free. All incoming email messages are automatically scanned to detect for viruses and to determine if the message meets specially defined "spam criteria."

How standard virus filtering works

As soon as an email reaches our mail servers, our virus filtering system scans the incoming message and any attachments using the latest virus definitions. If an email is found to contain a virus, the email is automatically deleted and a notification is sent to both the sender and the recipient. In a few cases, the sender will not receive a notification. For example, if the address from which the virus was sent is forged or invalid or if the virus filters out the sender's email address.

The virus notification includes the name of the virus and the email address specified as the sender's address. The email's subject provides detailed information, as the following sample email subject line illustrates:

***VIRUS***(from<random@yahoo.com>)(W32/Hawawi.G@mm)

Our virus definitions are updated on a daily basis to provide the greatest security.

Note: Emails that have already been scanned for viruses and which contain either X-Virus-Scanned or X-Virus-Hold in the header will not be re-scanned. The system does not scan messages less than 24 KB in size regardless of attachments.

How standard spam filtering works

Our spam filtering system, which utilizes SpamAssasin, is built around a set of spam rules that have been carefully developed to provide you protection from spam while reducing the number of valid email messages that may be mistakenly categorized as spam.

All incoming emails are evaluated against these spam rules and are assigned a "spam score." This score determines whether the message will be classified as spam. The threshold is set at 5, meaning any message with a score of 5 or higher is classified as spam. Messages scoring between 5 and 10 will be delivered, but will include a spam notification in the subject of the email so that you can immediately identify and delete these messages. The following illustrates a sample subject line of an email message that scores between 5 and 10.

***SPAM***FREE PAY-PER-VIEW for life!

Messages that receive a spam ranking above 10 are automatically deleted so that they do not end up in your in-box.

Note: Emails that have already been filtered for spam and which contain the X-Spam-Flag in the header are not checked. Emails greater than 150 KB are not spam filtered.
