Reading a Message Header

Each email message includes a header that shows the path of an email from its origin to destination. This information is used to trace a message’s route when there is a problem with the message. The Zimbra email message header can be viewed from the Zimbra Web Client Message view. Right-click on a message and select Show Original.

The following lines are in the message header:

Date - The date and time the message was sent. When you specify time, you can specify range by adding start and stop time to search for messages.

From - The name of the sender and the email address

To - The name of the recipient and the email address. Indicates primary recipients.

Message-ID - Unique number used for tracing mail routing

In-Reply-To - Message ID of the message that is a reply to. Used to link related messages together.

Received: from - The name and IP address the message was sent from. The header displays Received: from information from the MTA to the LMTP and from the local host.
