How to add Received header to the first position in MailMessage object

[licenses]

Scenario: I use SmtpClient to send message (previously received from Exchange Online) to the smart host. According to RFC I need to add Received header, so that it appears before all other headers.

I use Add method, because there are no Insert method:

ms.Headers.Add(“Received”, “value”);

Issue: My Received header appears after other Received headers. Is their API to add first header.

To see it in action:

var m0 = MailMessage.Load(“dsample.eml”,

new EmlLoadOptions { PreserveTnefAttachments = true });

m0.Headers.Add(“Received”, “Value”);

m0.Save(“sample-resaved.eml”);

Thanks,

Alex Shloma
