When you're working on stunnel, let us know the distro you're using. Some have packages to make installation easier, some don't. Once it's installed and starting correctly when the server starts up, configuration is easy. and that configuration can happen while the server is running, so that you can change users over as time allows.
Kev.
A couple of things that gave me trouble when upgrading are listed below. I hope these tips can help others who are planning to upgrade.
1. You need to open port 5767 for the new outlook connector to work
2. My sendmail configuration file was overwritten and i needed to add the spam assassin rules back into the new sendmail.cf
3. The custom webmail login page i created was deleted.
4. The webmail spell checker has stopped working. I haven't been able to fix this yet...
5. I needed to remove and recreate 2 users imap cache before their accounts would work again. If you run into a problem with a user there is a nice shell script in the wiki that removes the cache and creates a new one.

6. The server's load average was spiked for several hours while it re-indexed the messages for the search feature. This caused the server to slow down and for mail to start caching etc. until the indexing had finished.
I would recommend backing up your sendmail.cf file & any custom login pages you have, opening port 5767 before starting the upgrade, & running the upgrade during a time of day when the server isn't being used, after working hours, to avoid complaints while it runs the indexing service.
Also for anyone who is interested I am running this on Oracle Unbreakable Linux without any problems.
