Hi, I am struggling here - I have set up mail for my main domain. Webmail works, I have managed to set up my account on my MacBook Pro, but I get an error message when I try to set up the account on iPad and iPhone. I also tried to set the mail account up in Outlook, but that didn't work either. So I removed the account from my Mac and tried installing again and it went smoothly! My set up. I am using Lion Server, and I have installed the server using example.com. I have external DNS hosting, and DNS has the following setup: example.com - MX - mail.example.com mail.example.com - A - <my IP address> In the server admin app, I have my server running with Mail and DNS services running. Under the general tab in Mail I have example.com as Domain name and mail.example.com as Host name. When I set up the account on my mac, I only used example.com when asked for smtp- and incomming mail server (not mail.example.com). I got a warning regarding my SSL as I am just using the self signed certificate. This made me think that the problem was with the use of SSL. So I tried to disable SSL on my server, but still was not able to set up my e-mail on my iOS devices. Does anyone have any tips on what I might be doing wrong or how I can make use of my Lion Mail server?
