GroupWise Junk Mail feature

The vast majority of spam is processed through the Precise Mail anti-spam tool. You may want to review how that tool works before using the Junk Mail tool in GroupWise.

Despite extensive efforts to reduce spam at the server level with Precise Mail, some spam still makes it through to our mailboxes.The Junk Mail Handling tool is an additional step that GroupWise client (installed locally on the computer) users can take to reduce the amount of spam they get. Once the Junk Mail feature has been enabled you can block individual non-GroupWise e-mails or entire domains. The following are instructions for setting up and using the Junk Mail Handling tool in GroupWise on a PC although the process works the same for the Mac.

Please note: The more entries you have on the trust/block/junk lists, the slower GroupWise will perform as it has to compare every incoming email with the entries on those lists to determine what course of action to take. Also, you should periodically review those lists to make sure the entries are needed. Instructions for doing so are in the Tips section below.

Enabling Junk Mail

By using the Junk Mail Handling tool, you can filter your spam to either be completely blocked or go to a special folder called "Junk Mail" that you can look through later on, leaving only the important stuff in your Mailbox folder. The Junk Mail Folder will only become visible once the Junk Mail feature has been enabled and can only be set up using the GroupWise client, not GroupWise on the web. Although the screen shots below are taken from the PC, the functions are the same on the Mac.

To set up the Junk Mail feature,

  • Click on the Tools menu, then Junk Mail Handling.

Junk mail handling

On the Settings tab,

  • Click in the checkbox Enable Junk List to turn this feature on. Once this box has been checked, a Junk Mail folder will be created for you and placed in your folder list.
  • Click in the checkbox for Enable Block List to turn this feature on. You will NEVER see blocked e-mail. Use caution with this feature, especially when blocking entire domains as it could mean legitimate e-mail doesn't get through.

Adjusting the Junk Mail Settings

Also on the Settings tab,

  • You can specify whether you want junked e-mail in the Junk Mail folder to be automatically deleted after a certain number of days.
  • You can tell GroupWise to only accept e-mails and calendar items from people already in your address books.

Using the Junk, Block and Trust Lists

Junk List: this is where you add either entire domains (i.e. “” or “”) or specific e-mails (i.e. to automatically go to your Junk Mail folder rather than your Mailbox.

Block List: tell GroupWise to completely block a domain or e-mail address. These e-mails will never make it to your account.

Trust List: What if you want to block most of a domain? For example, you have a couple of contacts with hotmail accounts but you want to block everyone else from that domain? Go ahead and block the domain but then add entries to the Trust list to specify that certain e-mail addresses are okay even though you've blocked that domain.

  • Add entries to any of these lists by clicking on the New button.

Add address or domain

  • Type in specific addresses or entire domains and click OK.

You can also right-click on an incoming e-mail, go to Junk Mail from the shortcut menu select Junk, Block or Trust Sender.

Trust sender

Again, be VERY careful about blocking entire domains. Some spam e-mail appears to be coming from CWU users and some people are inadvertently adding the entire CWU domain to their block lists.

Junk Mail Tips

Periodically check your junk and block lists. Having a lot of entries on theses lists can slow performance as GroupWise has to match every e-mail you get with these lists to determine how to handle them.

Trust list

Note the Last Used and Count columns. If there's a zero in the Count column and the date in the Last Used column is older than two weeks or so, you probably don't need that entry anymore and can delete it.
