I have the same problem, this is my dns configuration (my IP / domain has been obfusticated, ip is a valid public ip):
/etc/hosts:
127.0.0.1 localhost.localdomain localhost
1.2.3.4 demo.mycompany.com demo somename somename.mycompany.com zimbra.mycompany.com mail.mycompany.com
hosts also had "mycompany.com" in the 1.2.3.4 line, while the A record for mycompany.com actually points to a completely different server. I removed this entry from the hosts line.
resolv.conf:
search dev.mycompany.local mycompany.local
nameserver list-of-valid-nameservers (6, as given by my service provider)
dig mycompany.com mx:
ANSWER SECTION:
mycompany.com. 300 IN MX 10 mail.mycompany.com.
ADDITIONAL SECTION:
mail.mycompany.com 300 IN A 1.2.3.4
dig somename.mycompany.com # this is the fqdn
ANSWER SECTION:
somename.mycompany.com. 14400 IN A 1.2.3.4
host `hostname`
somename.mycompany.com has address 1.2.3.4
My server was installed using demo.mycompany.com, but the server hostname changed. This did not cause any problems until I upgrades from zcs-5.0.4 to 6.0.1
localconfig.xml has zimbra_server_hostname set to demo.mycompany.com
There were some instances of ldap url's in localconfig.xml that referenced ldap://mycompany.com:389 - this would have worked with host lookups, i manually changed these to somename.mycompany.com after removing the mycompany.com entry from hosts.
after zmcontrol stop && zmcontrol start, i still get the error.  |
