CreateFromMailMessage generates duplicated From and To addresses #115
When using MimeKit.MimeMessage.CreateFromMailMessage static method to convert my .NET -MailMessage to a MimeMessage, i get a mail which has duplicates on the message.From and message.To collections.
I have a theory. Are you doing the conversion of your MailMessage into a MimeMessage after sending it via System.Net.Mail.SmtpClient?
Looking at Microsoft's reference source for MailMessage, it looks like the MailMessage.From, To, etc are not pushed to the MailMessage.Headers until the message is sent, but I'm not 100% sure about that (I've really just given their source code a quick glance).
