IMAP vs POP3

• With IMAP, you can have multiple folders on a mail server:
• Inbox
• Send
• Drafts
• Spam
• Special Folders
• IMAP allows you to read, move, and delete emails in these folders on the server. Also:
• You can track the read/unread status of the email.
• You can move an email from one folder to another.
• You can keep the same mailbox synchronized across multiple devices.

POP3

• POP3 only pulls Inbox.
• There are no folders, just a single stack of emails.
• When you pull the email, it is usually either deleted from the server or left (with the LeaveMessagesOnServer setting).
• Read/unread information is not kept on the server.
• You cannot move mail or manage it between folders.

Result

• IMAP = Full management and multi-device synchronization on the server.
• POP3 = Sadece Inbox’ı çek ve kullan, daha basit ve eski tip.
