Zimbra: Managing Spam

Zimbra: Managing Spam

July 6, 2011

Most filtering of unsolicited automated mail (aka "spam" or "junk mail") is handled by Zimbra's spam filter before those messages reach your Inbox. This filtering helps to reduce the amount of spam that is put in your Inbox.

In addition to the automatic spam filtering rules,  you can set your mail preferences to identify specific addresses to block or not block. You create a list of addresses that should not be allowed and addresses that always should be allowed. The spam filter uses this list to make sure you get the email you expect.

Spam buttonIf you receive a message in your inbox that should have been filed in Junk, click the Spam button in the toolbar just above the message list. This will move the message to Junk, and it will also copy the message to Zimbra's spam-learning folder, where the spam filter will be trained to recognize the message as spam. By clicking the Spam button you will help Zimbra learn what you consider to be spam mail.

Not Spam buttonWhen you are viewing the Junk folder, the toolbar button becomes "Not Spam" so you can use it to tell Zimbra when it has misfiled a message that you wanted to receive. Clicking the Not Spam button will move the selected message from Junk to your inbox, and train Zimbra to recognize that message as desired email.

Old junk messages are automatically purged from your Junk folder after 15 days, so you never need to worry about cleaning out the Junk folder.

Messages in your Trash folder are purged after 30 days.
