Remarks

The Received header is used for tracing the path a message has taken through various SMTP servers as it is transmitted from sender to recipient. Each SMTP server that handles the message adds a new Received header to the top of the message, creating a chronological trace of the message's journey through the email infrastructure.

A typical Received header contains several clauses that provide information about the message transfer, including:

from - the name of the sending host
by - the name of the receiving host
via - the physical link or protocol used
with - the mail protocol used (e.g., SMTP, ESMTP, etc.)
id - a unique identifier for the message
for - the recipient address

For more information, see section 4.4 of RFC 5321.
