Setting up external email on zimbra?

[reggiep]

Sorry to ask another zimbra question but looking through the admin docs on zimbra has left me feeling useless, or more useless that normal!
I am trying to test my installation to see if i can get it to sends and receive emails to the "real" world.
I have an external ip address and an mxrecord but I cannot see what I need to do to get these working.
I have added a domain - mail.tayna.eu (a spare one I have)
BUT I dont knonw wher to put these bits of info into the general info tab?

Could someone give me a hint?

Thanks

You just need to set up the relevant MX record (allow DNS time to propogate) and then configure a pinhole/port redirect through your firewall to port 25 on that server and the mail should just arrive.

Do I put my server name in the inbound smtp host name?

I'll give it til tomorrow as the mxrecord was only set up at about 12:00 today.

Thanks
