Zimbra 4.0.0.RC1 on Centos 4.3 running smoothly however I can see a lot of messages in active queue destined for root@mailhost.domain.com.

I have a fetchmail CRON process which uses zmfetchercfg script to aggregate mail for one of the users and this seems to be generating these emails.

I can send mail to root@domain.com without any issues, have also defined root alias in /etc/aliases to admin@domain.com and still messages are not being flushed ... after several requeue.
