if you set up POP to just leave messages on the server, how is the significantly different from IMAP? I love leaving important messages on the server, but I'm having problems finding a good email client for my Palm Pilot that does SSL and IMAP.
There's a whole write up
here, but these are the things I notice.
IMAP supports having folders and a directory structure to your account, rather than a single inbox.
IMAP also allows you to download message headers without downloading the entire message (this is theoretically possible with a pop program as well, just takes extra steps). This saves time and prevents getting stuck on a large message
You are also able to have multiple simultaneous logins to a single IMAP account, this allows multiple people to use the same email account and also prevents "POP Lock"(a problem where pop3 accounts get locked if a user does not exit his/her acocunt correctly.
And the obvious, wherever you go your mail will follow.. all of it, sent, deleted, etc.
While you can leave messages on a POP server, this is somewhat more of a hack. Because there are no server side flags with POP to allow a client to know if a message has been downloaded or not, your client then needs to keep track. Use more than 1 computer or client and things get off track, additionally even in a 1 client environment your client can lose track itself and redownload all mail stored in your pop account.
