Hm... I found the reason for:
Jan 17 02:49:41 wip postfix/local[5447]: 149681BCD111: to=<>, relay=local, delay=0.08, delays=0.01/0.06/0/0.01, dsn=5.1.1, status=bounced (unknown user: "emailuser")
The user emailuser doesn't exist on linux. If I add it:

Jan 17 15:06:26 wip postfix/local[28336]: 848591BCD137: to=<>, relay=local, delay=0.19, delays=0.04/0.1/0/0.06, dsn=2.0.0, status=sent (delivered to mailbox)
But obviously it goes to the mailbox of the linux user and not the virtual mailbox.

So here lies the problem. Which module handles this? And what's wrong with it's configuration? Note that before this I told ISPConfig to remake it's configuration files.

LE: The problem must be in SASL and in postfix. I'm running CentOS 5.4 i think (either this or 5.3) and the first thing I found is that the smtpd.conf file was not configured.
SASL's smtpd.conf file in centos is in /usr/lib/sasl2/smtpd.conf and ISPConfig tries to write /etc/postfix/sasl/smptd.conf
Anyway I configured them both properly.. I think:
