Charter.net Email Settings

General Definitions

  • SMTP: Simple Mail Transfer Protocol = SMTP stands for Simple Mail Transfer Protocol. SMTP is used when email is delivered from an email client, such as Outlook Express, to an email server or when email is delivered from one email server to another. SMTP uses port 25.
  • IMAP: IMAP stands for Internet Message Access Protocol. IMAP shares many similar features with POP3. It, too, is a protocol that an email client can use to download email from an email server. However, IMAP includes many more features than POP3. The IMAP protocol is designed to let users keep their email on the server. IMAP requires more disk space on the server and more CPU resources than POP3, as all emails are stored on the server. IMAP normally uses port 143.
    • Charter.net email has a storage capacity of 1 gigabyte. If the storage limit is exceeded, you may be unable to receive, send or delete messages. To prevent this from happening, log into your Charter.net email regularly and delete any unwanted messages.
  • POP3: POP3 stands for Post Office Protocol. POP3 allows an email client to download an email from an email server. The POP3 protocol is simple and does not offer many features except for download. Its design assumes that the email client downloads all available email from the server, deletes them from the server and then disconnects. POP3 normally uses port 110.
  • SSL: Short for Secure Sockets Layer, a protocol for transmitting private documents via the Internet. SSL uses a cryptographic system that uses two keys to encrypt data. Having SSL enabled is required to setup your Charter Email on your mobile device

Switching from POP to IMAP

To prevent losing your Email or Email folders when switching from POP settings to IMAP:

If you had "Leave messages on server" enabled since initial Charter.net Email setup, follow these steps:

  1. Create an imap enabled account for the Email address you want to switch to within same Email client. (Most modern Email clients can have both a POP enabled and IMAP enabled mailbox/account that share the same account credentials)
  2. Delete your pop mailbox account from the Email client

If you did NOT have "Leave messages on server" enabled since initial Charter.net Email setup or unsure, follow these steps:

  1. Ensure that you have the option "Leave messages on server" checked in your account settings on your Email client.  This setting should be available under "advanced settings" or something similar, depending on the client.
  2. If you have the option to disable Send/Receive in your Email client, disable it to ensure no new messages are delivered to the POP enabled mailbox/account.
  3. Create an imap enabled account for the Email address you want to switch to within same Email client.  (Most modern Email clients can have both a POP enabled and IMAP enabled mailbox/account that share the same account credentials)
  4. Move messages and/or folders by creating a storage or data folder (Outlook calls these PST), then drag and drop the messages/folders you wish to keep into the new folder.
  5. When you have moved over all of your Emails/Folders you can delete your pop mailbox
