But with STARTTLS is it a different protocol? Is the SMTP connection encrypted too? Sounds like a good basic summary. The key difference is that IMAPS is encrypted from the outset. IMAP with StartTLS allows you to connect first, then initiate encryption. >From a Courier perspective, with IMAPS, you are forcing anyone who connects to use encryption. If you use starttls, then you have the option to force encryption or simply allow it at the users discretion. Its a configuration option in the imap configuration file in your courier/etc directory (wherever that may be). I'm doing this from memory, since my courier server is at home. > A google on this doesn't really provide much help.
