Email Headers with POP

Apart from retrieving full mail messages, GemBox.Email can also enable you to get only the message headers. The headers contain information related to the message content and metadata. For more details, check out our Headers example.

To obtain the message headers, you need to use one of the PopClient.GetHeaders methods. The result is a HeaderCollection object, which contains a collection of Header objects.

The following example shows how you can receive mail message headers using PopClient.

        {
            pop.Connect();
            pop.Authenticate("<USERNAME>", "<PASSWORD>");

            // Get headers for first available mail message.
            HeaderCollection headers = pop.GetHeaders(1);

            // Display message headers.
            foreach (Header header in headers)
                Console.WriteLine($"{header.Name}: {header.Body}");
        }
    }
}
