As discussed in the blog, we have made significant infrastructure changes for v5.0 to support additional mail servers, most notably IMAP, Hotmail and Google Apps. The bulk of the development work to support these mail servers is complete, but the functionality is not ready for customer use.
We plan to provide initial test support for additional mail servers in the v5.1 beta, expected in early 2010. If you are interested in beta testing IMAP, Hotmail Connector, or Google Apps Connector support when it is available, please comment in this thread.
Also, please watch this post for future updates on IMAP support.
Thanks!
