I've just installed Zimbra on Fedora Core 4 and it seems to be running OK. I'm sending mail via an external smtp, which also seems to be working.

However, I set up a test account and sent an email from that address to itself and it would only work if I addressed it with the FQDN, e.g. sending a message to ray@mail.example.co.uk works, sending a message to ray@example.co.uk doesn't, I just get a bounce back from the server.

I'm sure there's something simple I'm overlooking but I can't figure it out. Any help gratfully received.

Best wishes
