It's not unusual that the size increases, because the attachments have 
to be encoded as plain text, but this is still a hint.

Maybe MailMate is encoding it in a way that Microsoft doesn't like. 
Based on your output it seems that MailMate *might* be unnecessarily 
re-encoding something as quoted printable and Outlook doesn't like that, 
but I'm not sure about that. Could you send me your examples (both 
variants) using “Help ▸ Send Feedback”. It's best if you first 
drag the emails out of MailMate and then use the Finder to 
“Compress” them. That way we can be sure MailMate doesn't re-encode 
anything when you send them to me.
