I've just downloaded and installed zimbra I created the admin user and used the web to log in. I created a user account. I can use that user to send emails; however, I can't receive emails for that user. The format that I've used for this user is abc@mailsever.domainname.com.

What am I missing, is this enough information? Is this the correct way to create a user? I host virtual domain and I'm looking for a good MTA will zimbra allow me to post multiple domains.
