I have just spent a couple of hours with Charter Tech Support tracing a problem with their email POP settings. Many people had been using mail.charterinternet.com and smtp.charterinternet.com as a POP account in their settings. This server was decommissioned on Wednesday, 10/26/2011. These settings no longer work. Charter advises on their website that you set the email up as an IMAP account and use mobile.charter.net. These settings work for me EXCEPT there is no option to leave the email on the server. If you check your email on your phone with these settings, the email will be deleted from the server. Charter is aware of this issue, and are planning to make changes to allow people to connect via POP to Charter to get their email. I will post a response here as soon as they call me back with the settings.
