Before configuring your mail access connection, it is important that you understand the two protocols (methods) commonly used to access email accounts: POP3 and IMAP.
- POP3: From the abbreviation Post Office Protocol, POP3 downloads emails from a server to a single computer or device, then deletes it from the server by default. Because of this, it can appear that mail is missing or disappearing from your inbox if you access it from a different computer. In addition, sent mail is stored locally on the client, not on the mail server. It is recommended to configure your POP3 email account to keep a copy of your emails on the server.
- IMAP: From the abbreviation of Internet Messaging Access Protocol, IMAP allows you to check your emails from multiple devices, such as a laptop, home computer or other mobile device. Sent mail remains on the server so you can see it from any device.
POP3 and IMAP sometimes add an extra layer of protection by encrypting emails for security and privacy purposes. See Email Encryption - SSL for details. If you have the choice between IMAP and POP3, it is better to use IMAP.
