How to add automatic response filter to roundcube?

I would be interested in that function, I understand that it would simply be adding sieve to the dovecot and the plugging in roundcube.

I have also added the following functions to one of my Hestia installations (This could be integrated in the future if there is any interest);

  • Z-push (For ActiveSync)
  • Spamassassin Userprefs (user filters that also works with a roundcube plugin)
