=== POP3 ===
POP3 support is implemented and landed as of v1.3. The server must support UIDL and TOP. These are probed for at account creation time and an error will be reported if they are not supported. See [[Gaia/Email/Implementation/MailSynchronization#POP3]] for important details on our implementation, such as the fact that we always leave messages on the server and never delete them.
