How to send non-alternative multiple parts using system.net.mail

I have emails with multipart/mixed body which contains nested multipart/related parts with Html part and related image part. Is there any way to construct these emails as MailMessage instances of System.Net.Mail?

This is not an alternateview question.

  1. multipart/mixed 1.1. multipart/related 1.1.1. text/html 1.1.2. image/gif 1.2. multipart/related 1.2.1. text/html 1.2.2. image/gif

1.1.1 is related with 1.1.2. But it is not related with 1.2.2. 1.1.1 and 1.2.1 are separate html bodies.

I have pasted a sample message below.

Message-ID: <[email protected]>

You can use some free library, check MailMessagesExamples.zip: http://www.lumisoft.ee/lswww/download/downloads/Examples/

Or google some other library.

Mime is pretty complex, to compose valid messages from string is hard, is some unicode chars inside.
