It seems all of a sudden, when I send an email from one account, another account is used. An example I send 'from' a@a.com. All recipients see another account b@b.com. I checked the account setting and no where is in a@a.com settings does it indicates the second email address No, I have not indicated that all responses from a@a.com should go to b@b.com address. Tried removing b@b.com account, and that does not help. It was working before, and nothing was changed
