Zarafa email only user

seabird

Hi everyone, maybe this is the wrong place to ask but I am running into some problems setting up a extra email address. I have a running setup with postfix and zarafa. The email is set up with the username being a physical user on the server.

Now I set up a extra domain for a temporary event and set up a email address:
zarafa-admin -c rsvp -p HtrHfxjm -e rsvp@example.com -f “Our name” -a 0

This worked and I can log in and send email. Receiving fails saying 550 no local recipient

My postfix/main.cf

mydomain = original.com
seconddomain = trial.com
thirddomain = example.com

mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, $seconddomain, $thirddomain

unknown_local_recipient_reject_code = 550

Am I overlooking a simple step?
