One problem with POP3 mail is that when you are downloading mails and suddenly an error has occurred, when you try to restart your download you will get duplicate mails!!! Now my inbox has over 8000 emails and its about 900MB in size, that would be very hard to manually delete those duplicate emails.
With IMAP hopefully that problem will be resolved since it has two-way syncing capabilities. IMAP stands for Internet Message Access Protocol. When using IMAP with GMAIL, all your labeled messages would arrive in folders, that is a label and inside the individual messages with its corresponding marks. Deleting a message in IMAP wont de deleted in GMAIL, you have to move it to the trash or delete it at GMAIL.
You can set your client to work offline to be able to download all your email messages, otherwise on most IMAP clients, it will only download the mail headers. When sending messages from your client creates new labels on GMAIL, they are marked as Sent Messages which indicates that the messages are sent from your mail client. When you create folders on your client they will be treated as label on GMAIL. There folder names which are reserved, they are Chats and Sent, when you try to create a folder with this name on IMAP they have a prefix IMAP/folder name on GMAIL.
