Technical Q.
1. In Mac Mail, what is the difference between a Gmail account with a 'G' and one with an '@' (see below)?
2. I have an active Gmail account, which is one of the 'G' ones, and a deactivated version of same address which is one of the '@' ones. I've had problems for months sending email, as it tries to use the '@' account, not the 'G' one, with resulting error messages. Causes me huge stress, and (literally) days of work time. Any ideas?
