What is POP and IMAP?
If you have ever tried to set up an email account, you would have noticed these terms. What are they? POP and IMAP are two protocols for accessing and viewing emails.
POP stands for Post Office Protocol. POP was created in 1984. It was used for downloading mail from a remote server.POP usually downloads all the mail from the server and deletes them from the server. Any changes made from a device won’t appear on other devices if you are using this protocol. For example,
- Saves server storage space.
- Messages are always accessible even without
theInternet because they are downloaded.
- Internet connection is needed only for sending and receiving mail.
- Any changes made on a device are to be made again on other devices.
IMAP stands for Internet Message Access Protocol. The first IMAP was developed by Mark Crispin in 1986. All mails rest on the server. Only a copy of the emails is downloaded. IMAP messages can be downloaded as parts allowing users to preview the mail.IMAP is useful for people using multiple devices.
- Mails are stored on the server
that you can access them with any devices.
- Changes made from one device are replicated on all other devices.
- Previewing messages.
- Saves device storage space.
- There might be size restrictions to
themailbox because email is stored on the server.
