This is how your Sent email is placed in the Sent folder when sending emails. IMAP is able to download emails from the server as well as upload them to the server.
IMAP synchronizes all email on the server with your client, which means that you can have read all your email on many different devices. It has a number of advantages over POP (Post Office Protocol) and no real disadvantages for most people. We recommend that customers who access their email with email clients such as Outlook, Apple Mail, and Thunderbird use IMAP (Internet Message Access Protocol) when possible.
