POP3 is two orders of magnitude simpler, has only a couple "extensions" or ways servers may be different, compared to IMAP which has a dozen commonly used extensions, so every "command" you implement as a client likely has 2-4 different versions depending on what the server supports. Then, there's the open question of how to handle different folders. I mean, it can be done, we did it later, but there's a reason POP3 was first and wide open but IMAP is restricted to a small subset of providers. And no, we do let people not use SSL, because we had a lot of folks who didn't. Especially now that we require ssl to have a valid cert. There's a big warning banner, but if folks don't have ssl, we didn't lock them out at the time. We might make a different choice now. Brandon
