I checked the preferences, but didn't find a switch for this. I'd like to prevent Mail from continually backing up the email that I'm writing at that moment. I write all of my personal emails from a Google account via Mail, and for whatever reason, whenever the email auto saves on my computer, it saves in Google too. So if I go back to look at a thread either via Google mail site or especially on my phone, I see a long, long list of emails in the thread when in fact there are only a few exchanges. My assumption is that somehow the auto save is being sent to the Google server too. I'd like to try shutting off the auto save and see if that solves the issue. Does anyone know how to do that? Thanks. EDIT: I'm using Mail 4.6.
