Pacific Online offers many advanced anti-spam measures to help protect your users from unwanted email. Each message received by Pacific Online is scanned for spam. Hundreds of tests are run on every message to determine the probability that message is spam. The email is then scored on the likelyhood the message in question is spam. By default messages with a score of  less than 10 are considered to be a low probability of spam, messages with a score of between 10 and 20 are considered a medium probability, and messages with a score of greater than 30 are almost always spam.

The text [Possible Spam] is prepended to each message that is scored as medium or higher. Mail that scores 30 or higher is automatically deleted. Domain administrators may override the scoring and default actions. Individual email users may also set custom actions. For example a domain administrator could configure their domain to move any messages with a score of 10 or higher into the junk mail folder and automatically delete any messages with a score of 20 or higher. Actions configured by individual users will override actions configured by domain administrators.

It is important to note that only mail in the Inbox will be downloaded when using POP. If you configure an action to move mail to the junk mail folder you should advise users to periodically delete the mail in this folder or eventually they will reach their disk space quota and be unable to receive new mail.

Domain spam filtering may be configured using the webmail interface while logged in as a mail administrator. To login as a domain administrator click the Mail Administration link in the Pacific Online Customer Control Panel. You may also create additional administrators who may login to webmail directly without entering through the Customer Control Panel. Once logged in to webmail as an administrator you will find the domain spam filtering settings under the Domain Settings menu.

Trusted Senders

Email addresses (ex: joe@example.com) or domain names (ex: example.com) can be added to your list of trusted senders. When email comes in from a trusted sender, all spam filtering for that email is bypassed. Enter one email address or domain name per line. Normal content filtering rules are still followed, however.

Your users may also maintain their own list of trusted senders at the account level. Email addresses in your users contact list are also considered to be trusted senders at the account level. Any emails that a user "unmarks as spam" will add the sender to their trusted senders list automatically.
