Hello. I'm sorry you had this inconvenience. I looked around for tracker reports on a similar subject but all I found was this one - MDL-50745 - and I am not sure it is the same as the email in question here is different. Perhaps if you agree and you don't find a more relevant report either, you could submit a bug? I am going to try replying to something by email with an email that's not gmail and see if I can replicate it .What happened when you replied to the message, even though it was the same email?
