My zimbra status page also show a "localhost" Host with all services down.
My setup is working, but I can't seem to remove this Host. The normal host is just working fine, I don't know where this one is comming from.

My config:

[Bash] acl_cache_credential_maxsize = 512 acl_cache_enabled = true acl_cache_target_m - Pastebin.com

My /etc/hosts localhost.localdomain localhost

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts trek.jverdeyen.be trek
