CalDav CardDav webmail client ?

[Marco]

Hello,

  I'm interesting in Cyrus Caldav/Carddav server. I never used it 
before, because most webmail solutions implement their own calendar and 
addressbook.

I wonder if I can interface Cyrus CalDav/CardDav in some opensource 
webmail, such as SOGo, Roundcube, or Horde Webmail.

Could you help me or tell me about your experience about these integrations?

Thank you very much
Greetings
Marco
