IMAP vs. POP3:

  • IMAP only reads your email on the server; it does not download or save email on your computer. Messages that you read, delete, or reply to will show up as such on the server and your email applications.
  • POP3 downloads and saves email on your computer. Messages that your mail application marks as read, deleted, or replied to will not show up as such on the server.
  • Both IMAP and POP3 use SMTP to send outgoing mail.
  • Using POP3 over SSL/TLS or IMAP over SSL/TLS provides increased security for your connections to the mail server.

Default Email Ports
Common email ports in cPanel are: POP3, IMAP and SMTP ports.

POP3 Email Ports
Post Office Protocol version 3, more commonly referred to as POP3, is the standard mail protocol designed to receive email sent from a remote server to an email client (local). This protocol allows for the messages to be downloaded to a local computer. Users can then read their emails even if they are offline, or if the device is not connected to the Internet.

It is important to note that when POP3 is used to connect to an email account, the email messages are downloaded to a local device and deleted from the servers. Once they have been downloaded, they can no longer be accessed through a different location. A benefit to using this protocol, though, is that it reduces the amount of email storage space used on the web server.

In cPanel, there are two default POP3 ports.

POP3 (110). The default non-encrypted POP3 port.
POP3 – SSL (995). The default POP3 port that allows for secure connections.

IMAP Email Ports

Internet Message Access Protocol, or IMAP, is another type of protocol designed for web-based mail. It allows for emails to be accessed via a remote web server, through the use of a local client. Like POP3, IMAP is also a very commonly used protocol for the purpose of retrieving emails. All newer web servers and modern email clients support IMAP and POP3.

One of the biggest advantages of IMAP over POP3 is that the latter allows for the simultaneous retrieval and access of email messages. It can be done via multiple clients.

In cPanel, there are 2 default IMAP ports.

IMAP (143). The default non-encrypted IMAP port.
IMAP – SSL (993). The default IMAP port that allows for secure IMAP connections.

SMTP Email Ports

Simple Mail Transfer Protocol (SMTP) is the industry-standard protocol used to send email messages. In cPanel, there are five default SMTP email ports.

SMTP (25). The default non-encrypted SMTP port.
SMTP Alternate (26). The most common alternate port used for SMTP traffic.
SMTP – SSL (465). The default SMPT port that allows for secure messages to be sent via SMTP.
SMTP Alternate (587). Another very common alternate port used by cPanel for SMTP traffic.
