mail/roundcube is a webmailer that has a managesieve plugin.
You'd also need to activate managesieve in `mail_plugins` in
Dovecot. See mail/managesieve for the plugin to (as it says)
manage your sieve configuration remotely. Additionally you need
sieve itself i.e., mail/dovecot2-pigeonhole.

I would like to add that Postfix's documentation indeed is great.
Have a look at

  http://www.postfix.org/documentation.html

and especially

  http://www.postfix.org/STANDARD_CONFIGURATION_README.html

for configuration examples for common use cases.
