I run 5.0.1 GA (Open Source on Debian Etch) and would like to use my existing (commercial) certificates I use right now for my webserver.

I would like to use the certificates for imaps and smtps. In 4.5.3 version I was able to use them, but in the 5.0.1 I can't figure out how to do so - the search didn't lead me to the solution...

Any ideas are appreciated.
