Using account aliases for mail hosted on 10.8 Server
I'm in the middle of researching how best to migrate from an old server running 10.5 server to a new one running 10.8 server. This particular server is used for DNS and Mail. I don't have any issues with the DNS, but playing around with mail on 10.8 server has given me a few headaches.
What I need to be able to do is have about 15 virtual domains, which I have managed without a problem, and also have email forwarding from a single email address to multiple accounts, which I have also managed without a problem. The last thing I need is to be able to have mail clients login using the email address as the username, to avoid having to arrange for 120-odd users to get their mail client settings changed.
So, I've gone into the advanced options for the user account, and set the alias for the account to be the email address, which I thought should have done what I need. However, when I check mail I get an authentication error. I know the password for the account is correct, and I can log in if I use the normal short username, but logging in with the alias just doesn't work. Anyone have any ideas how I can get this working?
