Unable to access webmail in browser and Mac Mail
I am a Mac convert from PC and I love my Macbook Pro with Retina display that came with Mountal Lion. Until recently after my visit overseas, I am neither able to access my ISPs webmail through Safari or Firefox on my laptop nor through Mac Mail app with unchanged settings provided by Road Runner, such as webmail.kc.rr.com, apop-server.kc.rr.com/smtp-server.kc.rr.com/110/25. Safari is too slow and hangs with connection errors for webmail. My ISPs id is my business id I use as I travel overseas constantly. I spent several hours and had my spouse call in local tech support and it is a pain having to call your spouse to login and forward email to a public email. Any help is appreciated as my ISP has been anything but helpful in resolving this issue blaming the OS.
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
