MIME header order

Question

Is it possible to specify the order of the headers in a MIME message? I'm setting some meta-data headers that our in-house application requires to be first in the generated eml file that I'm creating. Is there any way to ensure they'll appear first?

If I can't explicitly order them, can I remove/re-add headers or some other hack to make this work?

Answer 1

You can't explicitly order them, but you can use use MimeHeaderCollection's Insert method to add headers at the start of the list. If you are working with MailMessage object's, use its Header properties to access the header collection.

Yup, that worked. Thank you!
