In terms of email delivery, “spam” is unsolicited bulk email. Spam is generally considered junk email and can be a continuing annoyance to its recipients. It is considered poor netiquette to send spam.
The Spam Settings preferences in Workspace Webmail allow you to set behavior for filtering spam and adding email addresses to your Allowed List or Blocked List. Adding an email address or domain name to your Blocked List treats email messages from that email address or domain as spam and filters them based on your spam settings. Adding an email address to your Allowed List allows you to receive any message from that email address or domain.
You can turn your spam filter on or off, specify how to handle email messages that are identified as spam, and specify the level you want to use for filtering. For more information, see Use spam filter settings.
