I can neither send or receive emails. my computer has been out of use for a week while I have been on holiday. my operating system is OSX 10.9.4
my I mac runs on operating system OSX 10.9.4.
Having been on holiday for a week and not touching my system I find that I can neither receive or send e-mails.
I have looked at the mail doctor and note that my outgoing server is "offline" but cannot find any way to change this to "online".
Can anyone please help me???
