# Blocking Senders Reporting Spam / Phishing

This article describes how to block a specified sender or domain, as well as how to report spam or phishing to the Mimecast Security Team. The difference between the two actions is as follows:  
  
• Block a sender's address or domain. This added the sender's address or domain to your personal blocked senders list  
• Report the message as spam or phishing. This automatically triggers the following actions:  
  
 o The message is moved to your Junk E-Mail folder in Microsoft Outlook.  
 o The sender of the message is added to your Blocked Senders list.  
 o The message is forwarded to the Mimecast Security Team for analysis.

**Note: No notification is sent to the sender, if a message is blocked or reported for spam / phishing.**
