Why I need it... I am working on several projects and I want to have all the email communication sorted in folders based on projects name. I can't use filters based on email address, because lot of the people I work with appear in more than one project. That is why I manually tag incoming emails and use filters to move tagged messages from inbox to projects folders. I would like to have both recieved and replied (and sent) messages sorted into projects folders. But I don't know, how to do it... if there was a way to automatically tag replies, it would really help me. Or is there any other way? Thank you.
