MFMailComposeViewController Attaches Signature as .txt file

Question

I\'m sending a pdf through MFMailComposeViewController. The sender\'s signature is seen as an attachment when viewed in Outlook, but not the iOS native mail app.Everything else

Answer 1

After some more digging, this is an issue with the exchange server and not with Swift/ iOS/ etc. It has to do with the way that Exchange expects email content to be ordered. I haven't found a clear answer on if the newer versions of Exchange address the issue. The MIT link specifically mentions Exchange Server 2007 & 2010. Also, I was able to confirm that the issue is when the mail is being sent by Exchange, not received.
