Email Spam Filtering

Spam Filtering

Spam filtering effectively identifies and removes all spam messages reaching the 桃瘾社区 network through two levels of spam filtering:

  • First, it blocks and removes easily-identifiable spam when it first reaches the 桃瘾社区 network.
  • Second, it scans remaining messages using content-based rules, which detect and remove additional email threats.

These actions block most spam from penetrating the 桃瘾社区 network so intended recipients never see the spam in their Inbox. Spam will be delivered to the Exchange Junk Mail folder within Outlook or Exchange Online (). This will typically be a small number of email items as the majority of blatant spam email is caught and deleted.

Non-Spam Filtering

Email recipients may have at some point 鈥 either directly or indirectly 鈥 subscribed to newsletters, advertisements, or marketing messages from legitimate vendors and organizations. For instance, such subscriptions sometimes happen when attendees register for a conference, trade show, or work-related event. Spam filtering cannot determine whether or not the intended recipient wants to receive these legitimate messages, so it does allow them to go through to the recipient鈥檚 Inbox. If you do not wish to receive these emails, ITS makes the following recommendations:

  • Unsubscribe from each unwanted email by choosing 鈥渦nsubscribe鈥 at the bottom of the message. Do not provide any passwords or personal information when unsubscribing from these distribution lists.
  • For remaining emails that do not provide an option to unsubscribe, you can block the email via or
  • For emails from mailing lists that you want to continue to receive, but would like them to be automatically redirected to a different folder other than the Inbox, you can create a rule via or Microsoft Outlook.
