I hope you don't mind a couple of points about your blog entry and the installation of ZCS - this stands for Zimbra Collaboration Server (not suite).
The statements you make about the DNS are not correct, you have stated (in several places) that the FQDN of your server is "myemail.com" when that should be "domain name" and the FQDN is the hostname plus the domain name.
You also have this in your hosts file:
That should be the LAN IP address of your server not the loopback address and the format of that line should read as follows:
127.0.0.1 myemail.com myemail
The format of your DNS records is incorrect, they should be as follows:
192.168.1.100 myemail.myemail.com myemail
The configuration of DNS records, hosts & resolv.conf files is well documented in many forum threads and in the Split DNS wiki article.
myemail.com. 3600 IN MX 10 myemail.myemail.com.
myemail.myemail.com. 3600 IN A 192.168.1.100
