Server Rules

CUSTOMIZING ANTI-SPAM SETTINGS

To customize your Antispam settings use the ANTISPAM and the SERVER RULES sections under the SETTINGS option in your webmail.

ANTISPAM allows you to set the sensitivity of the standard Antispam filter

You may adjust the sensitivity of the spam filter. For most users, we recommend the DEFAULT setting

SERVER RULES allow you to filter all incoming messages and choose to Accept, Reject or Sort each message automatically.

You can white list some special addresses which are trusted even though the main Mail Server recognizes the message as Spam.
Or you can black list addresses which send spam messages but such messages are not recognized as Spam by the Mail Server.

There are two modes of Server Rules: Basic View and Advanced View. We recommend using the Basic View:

How To Add A Rule (See image below):

Make sure the ENABLE box is checked
Select the part of the message to check from the ITEM drop down box
Enter the text or email address to match in the STRING box
In the ACTION box, select the action to perform if there is a match to the String
Click the ADD button to add the rule and activate it. The new rule will appear in the FUNCTION rule box.

NOTE: Click on the rule in the to modify or delete it.

The Enable checkbox enables/disables the entire filter so that you don't have to delete filters if you want to deactivate all of them at the same time. YOU MUST PLACE A CHECK MARK IN THE ENABLE BOX FOR THE FILTERS TO WORK

The following shows a rule that has been added:

DISCRIPTION OF FIELDS:

Field	Description
Action	Actions specify the particular action that will be taken when the filter returns a positive result based on the condition of the message content. Reject Rejects the message so the message will not be received and all following filters will not be processed. Accept This action clears the spam flag and immediately accepts the message and all following filters will not be processed. It is a white listing action. Delete The delete action is something between the Reject and Accept. It does not accept and deliver the message but also does not reject it. It accepts the message but does not return any false response and does not deliver it. Mark as spam This action sets the Spam flag of the message so it will be processed according to the Instant Anti Spam settings of the user. Forward In such case, user has to fill also an Address option by email account to which the message should be sent and choose the type of message - whether email message or a message to IM. Notify This is similar as the Forward action but you can specify different content of sent message. You can even use variables in the message. Fill complete message with headers to the Message text area. Additionally, you do not have to specify some specific format in Message text area. Only a text of message which should be sent.
