The using of IMAP to access your mailbox has advantages over POP3 and the difference of their working mechanism can be summarized in the following table.
|Since email needs to be downloaded into desktop PC before being displayed, you may have the following problems for POP3 access:
The downloaded email may be deleted from the server depending on the setting of your email client.
|Since email is kept on server, it would gain the following benefits for IMAP access:
|All messages as well as their attachments will be downloaded into desktop PC during the ‘check new email’ process.||A whole message will be downloaded only when it is opened for display from its content.|
|Mailboxes can only be created on desktop PC. There is only one mailbox (INBOX) exists on the server.||Multiple mailboxes can be created on the desktop PC as well as on the server.|
|Filters can transfer incoming/outgoing messages only to local mailboxes.||Filters can transfer incoming/outgoing messages to other mailboxes no matter where the mailboxes locate (on the server or the PC).|
|Outgoing email is stored only locally on the desktop PC.||Outgoing email can be filtered to a mailbox on server for accessibility from other machine.|
|Messages are deleted on the desktop PC. Comparatively, it is inconvenient to clean up your mailbox on the server.||Messages can be deleted directly on the server to make it more convenient to clean up your mailbox on the server.|
|Messages may be reloaded onto desktop PC several times due to the corruption of system files.||The occurrence of reloading messages from the server to PC is much less when compared to POP3.|
