Mail not automatically checking
For the past few weeks my Mail has intermittently stopped automatically checking. Sometimes it does and then I might be an hour or so without any mail so I check manually and there will be about five or six messages.
I've tried changing the preferences on and off but I can't think what else I can do.
Anybody any ideas, please?
