In the past days I haven't been able to check my work email from home with my Powerbook. I have a Comcast account at home with a wireless network, the Comcast email works flawlessly, but the work email can't connect to the server. If I'm at work (Verizon Dsl w/wireless network) the email works with the exact same settings. The email is on a dedicated server at hostcentric.com, so it has nothing to do with Verizon or Comcast. Any idea?
