True or False: Greylisting attempts can be viewed in the Connections viewer.

Greylisting is a technique used in email filtering to temporarily reject emails from unknown senders, thereby discouraging spammers who do not retry sending emails after a temporary failure. This mechanism generates entries or logs that can be observed during the email processing lifecycle.

When using the Connections viewer in Mimecast, users can indeed monitor various connection attempts related to email transmission, including those involving greylisted emails. The Connections viewer displays details on incoming and outgoing emails, allowing administrators to analyze connection patterns, including those that align with greylisting practices. This reinforces the fact that greylisting attempts are a part of the connection data that can be viewed, helping to troubleshoot email delivery issues and identify potential spam or malicious threats.

Thus, stating that greylisting attempts can be viewed in the Connections viewer is accurate, confirming the true nature of the statement.
