How to set up an IMAP email account
POP (Post Office Protocol) is one of the oldest email protocols still in use. While it is widely supported by most email providers, it lacks several features found in more modern protocols. For example, POP does not support searching for emails on the server, organizing messages into folders, or instant email retrieval (also known as push notifications). Because of these limitations, it is recommended to use POP only if your email provider does not support a more capable protocol like IMAP or Exchange.
