We have done what we can from an internal testing standpoint.  Would
really love some real life feedback on the beta bits or the latest
Fedora releases to see if we have been successful.  So, how about it,
participate by pulling the RHEL 5.3 beta version, configure courier-imap
with real data and provide feedback.  This is an opensource community
effort, am sure Steve Whitehouse would love to have feedback, analysis,
patches, etc..... :)

Thanks
