Correct. This is the major difference between POP and IMAP. POP is a simple delivery facility for email: when you access it it downloads the entire mailbox from the server to your local system then (by default) deletes the content on the server. So your local system's version is the one true version of your mail that has already been delivered. Some POP servers support options to not delete the content on the server, but that means they'll all get downloaded again next time. Also you can't "upload" things to a POP server so information like what messages you've replied to, what's been deleted, etc. cannot be updated on the server. It all exists only on your local system. IMAP is fundamentally different: the master copy of mail is left on the IMAP server and your local mail client interacts with the server to perform actions like retrieve mail, delete mail, move messages between mailboxes, etc. This lets you have multiple mail clients access mail and see a relatively up-to-date view of your mail. It also means that any messages stored locally on your system are merely cached there for performance reasons, and you can delete your local disk cache and they will not be lost. But of course, once something is deleted on the server you can't access it any more locally, usually, unless you've made a backup. There are lots of articles on the web about the differences too.
