Trouble with email connections.
So I have two web based mail accounts, outlook.com which I access using thunderbird, and gmail which I access using mail. Both are having intermittant connection issues. At the request of my ISP I have bypassed WiFi and gone hard wire to modem, in fact I have now tried two modems, both are having the same problem.
I used the Mail assistant tool, but it just recommended settings that were already OK. Sites ping OK, web access to both is OK but they don't connect with my mail apps, I get this "The server “smtp.gmail.com” cannot be contacted on port 587"? Well now I see that the mail I wanted to send has in fact gone, as I said this is intermittent. My Imac is running OS X v10.9.5 any suggestions?
