I have users in ldap and aliases in /etc/aliases and i use postfix. There is an alias testuser@hostname for tuser@hostname. When tuser uses sieve vacation and uses the :addresses options with his email address (tuser@hostname), the response is also sent, if a mail to testuser@hostname is sent. in the postfix master.cf the line for deliver is flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} -a ${original_recipient}
Looking at the code.. It checks To: Cc: Bcc: Resent-To: Recent-Cc: and Resent-Bcc: headers. If either ${original_recipient} or any address listed in :addresses is found from any of those headers, it's ok. So one of those has to match in your system. (Have you checked if ${original_recipient} is tuser or testuser?)
BTW. Stephan, http://wiki2.dovecot.org/Pigeonhole/Sieve/Usage is more or less out of date related to these rules.
