I'm new with zimbra and i did my first install (Release 6.0.1_GA_1816.DEBIAN5_64 DEBIAN5_64 FOSS edition.) following guides and wikis, well everything went good so far until i started testing the email capacity of zimbra. At first i tried sending emails to gmail yahoo and hotmail, well they arrived quickly but when i tried to send email to a private domain i can't i instantly get a message like this:
Well the hostname of my machine is zimbra.mydomain.com and i do have reverse dns and mx entries, well this server is a subdomain of mydomain.com wich is located in another machine (dunno if this has something of importance), also there is a ton of logs and i don't know which ones are those who register this type of errors.This is the mail system at host zimbra.mydomain.com.
