Hello Patrick,

you do not need to open the sieve port to the whole world. Only allow
the connection from the webmail server - which may (or may not) be
localhost.

I have tried various sieve plugins for mail clients (thunderbird,
kmail), and I could not find anything comparable to managesieve plugin
for roundcube. Usually it was just a text editor for uploading hand
written sive scripts... So most users will be using webmail to configure
sieve.

Just uncomment the sieve line in cyrus.conf

I think roundcube+managesieve plugin is the best. I think that there is
even an option in managesieve to enable a simplified "vacation only"
interface. (But I'm not sure in which version it is).
