Is it already possible to determine which project (horde/kolab) is to "blame"?
As I can use smtps from kolab with kmail, I would blame horde.  But I guess
that there horde users that can perfectly well use smtps, but I have
actually no idea whether the last statement is true.  How to test?  Using
wireshark?  That's not easy as the contents of the packages can't be checked,
because they are scrambled...
