SPEmailMessage "Base mail message"

Question

I created a Email Event receiver for a list which creates a DocumentSet and drops the mail message as .eml file in the DocumentSet. Attachments will also be dropped inside the DocumentSet. So far so good... The mail will be send to the list from a client application. The client application simply forwards a user mail to a sharepoint list depending on the subject. User mail with attachments --> application --> sharepoint list with mail receiver

I got a requirement to set the sender address as a metadata value. My problem here is, that I only receive the address of the application which forwards the mail.

Is it possible to get the base mail message which was send to the application? Or only the sender which originally has send the message?

Thank you very much!

Answer 1

So SPEmailMessage.Headers usually does not contain all of the information that is sent with the email (annoying right?). What it does have is a method that allows you to get a stream of the original email message SPEmailMessage.GetMessageStream(). I would use this to populate an object of type System.Net.Mail.MailMessage and then you should be able to access everything that was sent in the original message. Take a look at this codeplex tool it may do a lot of the heavy lifting for you.
