I applied the update script "smeplus" (found on this site) to my server and then the cyrus user could not authenticate to the server anymore. I guess that any future version of sme-server would also include quite a few of these rpms. I now fear for my cyrus-imap that won't get updated together with the server.
I'm not knowledgable enough to update this package (cyrus-imap) and that's too bad. It is a really great service (ie: sharing mail folders).
