=== Postfix ===
Adjustments to Postfix main.cf

/etc/postfix/main.cf
virtual_transport = procmail:
mailbox_transport = procmail:
# be sure to only deliver to procmail one user at a time:
procmail_destination_recipient_limit = 1
# we use virtual_alias_* to redirect mails for local postmaster/root etc. to another server:
virtual_alias_maps = hash:/etc/postfix/virtual
# replace THISHOST with your host FQDN (example: zarafa1.foo.bar)
virtual_alias_domains = THISHOST
# the SQL file needs the Zarafa query for users
virtual_mailbox_maps = mysql:/etc/postfix/zarafa-users.sql, hash:/etc/postfix/virtual
# the SQL file needs the Zarafa query for domains
virtual_mailbox_domains = mysql:/etc/postfix/zarafa-domains.sql
virtual_minimum_uid = 500
virtual_uid_maps = static:500
virtual_gid_maps = static:500

/etc/postfix/master.cf
procmail unix - n n - - pipe flags=DORX user=vmail argv=/usr/bin/procmail -t -o SENDER=${sender} -m USER=${user}@${domain} DOMAIN=${domain} EXTENSION=${extension} RECIPIENT=${recipient} /etc/procmailrc

This sets the variables SENDER, USER, DOMAIN, EXTENSION, RECIPIENT for use within the procmailrc script. See "man procmailrc" for explanation, if it's not already clear what they mean.

=== Procmail ===

/etc/procmailrc
SHELL=/bin/bash
LOGFILE=/var/log/procmail
VERBOSE=on

# debugging: remove "#" from the beginning of the line
#LOG="DOMAIN=$DOMAIN, USER=$USER, SENDER=$SENDER, EXTENSION=$EXTENSION"
############################################################################################
# Domain Filter
############################################################################################
:0
* $DOMAIN ?? our.domain.example
{
# this filters SPAM to the junk box in Zarafa for all users in this domain
:0w
* ^X-Spam-Flag: yes
| /usr/bin/zarafa-dagent -j $USER
EXITCODE=$?
}

############################################################################################
# User Filter
############################################################################################
:0
* $USER ?? this.user@our.domain.example
{
# mail that arrived at the spamtrap is filtered to this box.
# Remember: \\ is the folder separation!
# Remember: X-Original-To: is only inserted when you have single recipient delivery, and procmail was called with flags=O
:0w
* ^X-Original-To: spam-trap@otherdomain.example
| /usr/bin/zarafa-dagent $USER -CF Inbox\\SPAM_trapped
EXITCODE=$?
}

############################################################################################
# Default/Fallback Action
############################################################################################
:0w
| /usr/bin/zarafa-dagent $USER
EXITCODE=$?

Remember that flags=DORX is important for procmail in master.cf, it gives you a lot of needed info into headers. Don't forget to setup single recipient delivery in main.cf, otherwise procmail will do a mess.

Of course you'll want to expand /etc/procmailrc, this is just a basic example and good for first testings. Look into /var/log/procmail for filtering details. Set verbose=off if no logging needed.
