What is POP3?
About POP3 Protocol
The Post Office Protocol version 3 (POP3) is a standard protocol used for receiving emails from a remote email server to a local email client. It operates over port 110 by default and is widely supported by email clients and servers. POP3 downloads emails from the server to the client device, allowing users to access their emails even when offline.
Advantages
Offline access: POP3 allows users to download emails to their local devices, enabling offline access to email messages.
Simple setup: POP3 is relatively easy to configure and use compared to other email protocols like IMAP.
Reduced server load: Since emails are downloaded to the client device, POP3 can reduce the load on the email server.
Cons
Limited synchronization: POP3 does not synchronize email actions across multiple devices, leading to inconsistencies in email management.
No folder support: POP3 lacks support for server-side folders, making it challenging to organize emails on the server.
Email retention issues: If emails are downloaded and deleted from the server, they may not be accessible from other devices.
