Difference between pop3 and IMAP:

1. POP3 provides a fast email service, and users can use POP3 to read the letters in the server to the PC offline. Once the email is on the PC's local hard drive, you can choose to delete the email from the server, then disconnect from the Internet and read the email at any time.

2. IMAP also provides a convenient Dongshan mail ** service, so that users can read offline, IMAP provides two-way communication between Webmail and email client, the operation of the client will be fed back to the server, the operation of the email, the mail on the server will also do the corresponding action, to achieve synchronization everywhere.

3. IMAP is more convenient, intelligent, fast and stable than POP3, IMAP synchronizes with multiple clients and servers in multiple places, while providing users with more convenient email services, it also greatly improves the speed of sending and receiving, and reading emails.

IMAP and POP3 protocols are used to receive Menghong emails, the difference between the two, simply put, using POP3 protocol, the emails on the server will be all "**" to the local area; The IMAP protocol can directly operate the emails on the server through the mail client instead of all the emails.

1.When using the Internet Message Access Protocol (IMAP) protocol, the user's actions on a mail client are "mapped" to the mail server. Therefore, with the IMAP protocol, it is possible to keep messages synchronized on multiple mail clients at the same time.

2.When using the POP3 protocol, the user's operations on the email client (e.g., deleting, transferring to other folders, etc.) on the email client will not affect the emails on the server. However, if the user does not check "Keep a copy of the message on the server", the local message will be different for different mail clients.

The protocol improves the shortcomings of POP3, is more flexible and convenient to use, and is very suitable for operating emails between different computers or terminals, and the IMAP protocol can be set as the receiving protocol in the mail client.

The difference between IMAP and POP3 is that IMAP does not need to perform all the emails on the server (according to actual needs), and can operate the emails through the email client. POP3 allows the mail server to send all unread emails from the server to the computer and delete the emails on the mail server at the same time (many mail servers currently support emails, do not delete the emails, or send reminders).

IMAP provides two-way communication between Webmail and the email client, and the operations on the client (such as: read, delete, mobile mail, etc.) will be fed back to the mail server, and the mail will also be fed back to the mail client when the email is operated on Webmail (i.e., the email and status viewed by logging in to the mailbox on the email client and browser are the same).

POP3 operations on the client (e.g., read Jane Preparation, delete, move email, etc.) will not be fed back to the mail server, for example, when moving the emails on the client to other folders, the mail server will not move these emails at the same time.
