To adjust Anti-Spam Aggressiveness


Anti-Spam Aggressiveness controls how aggressively emails are classified as spam.  Care should be taken when adjusting this setting and we recommend never moving more than one level.   


  1. From the main Mail Control page, click on Change your spam handling preferences in the Common Tasks menu

  2. Select Spam Handling from the menu near the top of the page
  3. Select the level aggressiveness level, then press the Save Changes button

  • Very high:  Detects virtually all spam (typically well over 99%). False positives are likely unless whitelists are used extensively.
  • High:  Detects a high percentage of spam (typically upwards of 98%). False positives may occur on occasion with certain types of emails (e.g., marketing communications that are very aggressive in tone and other mail that includes "spam-like" elements), but given the ease of whitelisting these sources, this relatively aggressive posture can allow for a very low number of false positives while continuing to detect a very high percentage of spam.
  • Medium:  Detects between 96% and 98% of spam. False positives are very rare.
  • Low, Very Low, Unfiltered:  we do not recommend using these settings

 

To manage your whitelist


Adding an email address to a whitelist will allow email from that address to bypass the spam filter.  You can add individual email addresses to your whitelist, or use a single entry to allow all email from an organization.


  1. From the main Mail Control page, click on Change your spam handling preferences in the Common Tasks menu

  2. Select Whitelist from the menu near the top of the page

  3. Click inside the gray box listed under “show system-wide default entries” and add your entries.  To add an individual address, simply type the address in the gray box (for example: importantperson@importantcompany.com).  To add a company, enter only the part of the email address that follows the @ sign (for example:  importantcompany.com).
  4. To remove an address from the whitelist, simply delete the entry from the gray box
  5. Press the Save Changes button


To manage your blacklist


Adding an email address to a blacklist will cause any email from that address to be marked as junk mail.  You can add individual email addresses to your blacklist, or use a single entry to allow all email from an organization.


  1. From the main Mail Control page, click on Change your spam handling preferences in the Common Tasks menu
  2. Select Blacklist from the menu near the top of the page
  3. Click inside the black box listed under “show system-wide default entries” and add your entries.  To add an individual address, simply type the address in the gray box (for example: spammer@spammer.com).  To add a company, enter only the part of the email address that follows the @ sign (for example:  spammer.com).
  4. To remove an address from the blacklist, simply delete the entry from the black box
  5. Press the Save Changes button


To manage Junk Mail Digests


Mail Control can automatically send you an email that lists each spam message received since the last digest was sent.  This allows you to easily look for an false positives (legitimate emails that were flagged as spam).  You can have up to three digests sent per day, although once per day is usually sufficient.


  1. From the main Mail Control page, click on Change your spam handling preferences in the Common Tasks menu
  2. Select Digests & Notifications from the menu near the top of the page
  3. Under Send Digests on These Days, select the days you wish to receive digests.
  4. Check the Do not send empty digests option in the Skip Empty Digest section
  5. Under Time of Day, use the 1st menu to select the time you wish to receive the digest.  Use the 2nd and 3rd menus if you wish to receive more than one digest per day
  6. Press the Save Changes button
