Rejoice, ye Apple-achians. Here's a Mac-Mini newbie who's coming off many years of Windoze usage.
Mountain Lion/Mail 6.1 (1498) is displaying my SMTP server name with suffix "(Offline)", and outgoing mail fails. How to fix? My ISP's tech support & I spent 45 mins. on the problem and can't for the life of us find anything in "Preferences" or Connection Doctor about it. There is no problem at the ISP's end.
