Our application is sending our emails with Word attachments using System.Net.Mail. We have empty-string as our plaintext bodies. The application receiving these email messages sends them as faxes, with the result that the fax machines prints an unnecessary blank page for the empty plain-text body.
Is there any way to force System.Net.Mail to not send any body at all?
Alternatively, setting the email to use the multipart/alternative mime type (it's currently using multipart/mixed) seems like it should fix this problem, but I don't think it's supported. Any ideas for how to make System.Net.Mail do this?
