Dealing with Spam


All emails arriving in your mailbox are passed through generic spam and virus filters to remove unwanted or nasty material, but due to the varying definitions of what people consider spam, the settings must be very conservative. To assist with this, every mailbox comes equipped with a personal spam filter that can be configured for your needs.

You can set the spam filter to delete the spam messages, mark them as spam by changing their subject, or move them to the special spam folder accessible by mail clients over IMAP. The spam filter uses a wide variety of local and network tests to identify spam signatures.


To Manage Your Personal Spam Filter Settings

  1. Log into your control panel found on the upper right of our website at DDNS
  2. Select Products / Services on the left-hand side, then click Manage. Then click the Login To Plesk from your control panel. This is where you manage all aspects of your email hosting including the spam filter settings.
  3. Click on Mail, then select the email address you wish to manage. Then click on Spam Filter.

Spam Filter Score

The Spam filters perform a number of different tests on contents and subject lines of each message. As a result, each message scores a number of points. The higher the number, the more likely a message is spam. By default, the filter sensitivity is set so that all messages that score 7 or more points are classified as spam. To make the filter more sensitive, try setting a lesser value, eg. 5. If you are missing email because your spam filter thinks they are junk, try reducing the filter sensitivity by setting a higher value, eg. 8


What can I do about Spam Messages arriving in my Inbox?

Drag these into your SPAM folder.  Our system periodically learns all samples found in this folder to improve detection.

False Positives.  I've found a message I consider to be legitimate in my Spam folder.  What can I do?

We do our best to avoid these but if you find legitimate messages in the Junk folder dragging these into your INBOX.  This will cause our filters to learn the message as Ham.  In most cases this will solve the problem, however if the issue persists please contact us via support@ddns.com.au.  We will need to review some samples to determine the cause.
