i have installed Zimbra 6.04 on Centos 5.4 on a vmware. i have some problems with understanding all things. first i want to know about the /etc/hosts. i put in there 192.168.1.2 - zimbra.mydomain.com. But my MX-Record is set to smtp.mydomain.com. so what is the right for /etc/hosts? is the zimbra.mydomain.com for the external login? where i set the mx recorded domain? i dont can't send any email, not intern or extern, every mail is in the queue, connection time out on zimbra.mydomain.com. what for settings i must make for my MX-Domain smtp.mydomain.com?
