The terms of POP3, IMAP & SMTP are often heard when setting up mail client configuration in computer or SmartPhone, even now many of mobile phones with a low entry price was already equipped with email facilities.
But do you know what are they meant by POP3, IMAP & SMTP? In this article I will try to describe what the three terms above.
POP3 (Post Office Protocol version 3) is a protocol used to retrieve electronic mail (email) from the email server. POP3 protocol was created because of the design of the electronic
mail system that requires the server to accommodate email for a while until it’s taken by an eligible recipient.
IMAP (Internet Message Access Protocol) is a standard protocol for accessing / retrieving e-mail from the server. IMAP allows users to choose e-mail message that he will take, make a folder on the server,
search for specific e-mail messages, even deleted e-mail messages on server. This ability is much better than POP (Post Office Protocol) which only allows to retrieve/ download all the messages without exception.
SMTP (Simple Mail Transfer Protocol) is a commonly used protocol for sending electronic mail on the Internet. This protocol is used to transmit data from computer sending email to the recipient mail server.
From the comparison above you can see how IMAP do better than POP3 for synchronizing folders and Rule to Webmail.
For you using the mobile phone, I think it is better to use IMAP protocol, because by using the IMAP protocol you can set whether the email is received along with any attachment or just the header.
Okay, it is enough for the lesson, I hope you can differentiate between POP3, IMAP and SMTP now.
See you…

Look at table below for the comparison between POP3 and IMAP
Descriptions | POP 3 | IMAP |
Email can be left on the Server | “leave message” setting have to be enabled | Automatic |
Email with its attachments directly downloaded to local PC | Automatic | “Download all header and attachment” setting have to be enabled |
Folder created in Outlook automatically appear in Webmail and the opposite | No | Yes |
Read new message | Fast | Delay about 1-5 seconds |
Rule/ Filter made in Outlook/ client automatically apply in Webmail | No | Only rule from Webmail applicable for Outlook |
Email Backup | Email backup done manually unless “leave message on server” setting enable. | Automatically email backup |
Delete email | Deleted email go straight into “Deleted Folder” | Deleted email will be marked streak on its header. To remove it permanently done “Purge Deleted Messages” |
For you using the mobile phone, I think it is better to use IMAP protocol, because by using the IMAP protocol you can set whether the email is received along with any attachment or just the header.
Okay, it is enough for the lesson, I hope you can differentiate between POP3, IMAP and SMTP now.
