New Centos 7 kolab 3.4 install

[dsp3]

It's been a while since I setup a new server and I have run into issues 
on vanilla Centos 7 install.
I can login to admin console and create users, but users can't 
send/receive mail, locally or externally. Postfix and Cyrus appear to 
work. It appears that the problem is with amavisd:

systemctl status amavisd -l
● amavisd.service - Amavisd-new is an interface between MTA and content 
checkers.
    Loaded: loaded (/usr/lib/systemd/system/amavisd.service; enabled; 
vendor preset: disabled)
    Active: failed (Result: start-limit) since Mon 2015-12-21 20:39:08 
EET; 31min ago
      Docs: http://www.ijs.si/software/amavisd/#doc
   Process: 1329 ExecStart=/usr/sbin/amavisd -c /etc/amavisd/amavisd.conf 
(code=exited, status=255)

There is also dirserv:

service dirsrv status
Redirecting to /bin/systemctl status  dirsrv.service
● dirsrv.service
    Loaded: not-found (Reason: No such file or directory)
    Active: inactive (dead)

Also, no maillog file in /var/log/

What's going on?
