Support for TLS (STARTTLS) in IMAP email accounts?
As far as I can tell, the Windows 8 Mail application only support IMAP (incoming) using SSL on legacy port 993 and not the more modern STARTTLS (TLS) connection type. Usually on port 143. I find it odd that this is not supported, because STARTTLS is supported for SMTP (outgoing).
Is there a good Windows 8 UI-style application with support for this security that I can use as a replacement for the Mail application?
I can use Opera Mail or Thunderbird in the Desktop, but I am interested in attempting to stay in the new UI-style.

Based on initial testing on Windows Phone 8—I have only had 25 minutes with my new device—the support is the exact opposite on Windows 8 from Windows Phone 8.
Windows 8 supports STARTTLS for SMTP but not IMAP. Windows Phone 8 on the other hand support STARTTLS for IMAP but not SMTP.
Shoot me now. I will investigate further with a server where I can record the exact data transmitted between the client and server.

Just in case you haven't found an answer yet:
Have you tried adding the TLS SMTP port number to your mail server as in mail.server.com:587 ?
Worked for me (after spending hours of debugging, log parsing, reconfiguring, ...)
