[Dovecot] web interface for user creation/vacation

[Chris Cappuccio]

What are the best web interfaces for user/domain management, perhaps one that also allows individual users to edit vacation msgs?

Right now I'm using a postfixadmin based mysql control panel.  Curious what is the better stuff out there that people are using with dovecot/sieve these days?

Are there any decent front-ends to setup/manage per-user sieve filters?
