Desk makes use of a spam detection and filtering server, but on occasion you may want to set your own rules to either ensure that mail from certain senders is always or never marked as spam.

The characteristics that Desk implements for both whitelists and blacklists are the following:

  • Specific Email address (spammers@spam.com)
  • Email domain (spam.com)
  • Subject (Want to buy some spam?)
  • IP Address of original sender (127.0.0.1)
  • Match all senders, ensuring that no e-mail is ever automatically marked as spam (*)
If you are an administrator on your Desk installation you can manage the whitelist and blacklist by going to Settings -> Company -> Spam Control.
