Instead of logging in as "administrator", you will need to login as "admin". That will take you to the server admin panel.

We need to have an email account named admin@ that is not monitored by the system administrator.  That's why I named the system admin account "administrator".  Administrator even shows up in the user account list as the primary administrator....  Screenshot:  http://screencast.com/t/XpTNskDkyx1

 

Surely you're not suggesting that the only way to get to the system administration panel is that the primary administrator account must be named "admin"...  There has to be a link or some other way...right?

 

 

IIRC, during the setup process you are prompted to enter a System Administrator login. This login does not login to any domain on the server, but to the server admin area. In my case, I named my server admin account "admin" and then my domain administrator is named administrator@domain.com. 

 

Were you not given an opportunity to create the server admin account? If you were...at least in my case....I simply log off of the domain administrator account and then log to the system (server) admin account. I have not seen a way (or a link) to get from the domain administrator account directly to the server admin, but you can go the other way. If you first logon to the server admin account, you can then click Domains, click on the domain you want to manage, then click the Manage button. The domain admin account will then open in a new tab in your browser, so both will be available at the same time.

 

Hope this isn't confusing....

 

Daemach, when you log in as your "admin" account you are using the full domain too yes ? "Admin@yourdomain.com"

When you log in as your "administrator" just use "administrator" no domain.

 

I set up the system administrator user during the setup wizard - it asked for a name so I chose "administrator", because we want a separate email account named "admin".  That account is listed as the primary administrator for the server:  http://screencast.com/t/XpTNskDkyx1

 

When I log in using "admin@calebnetwork.org" I get the standard user interface.

 

When I log in using "administrator", with no domain, I also get the standard user interface:  http://screencast.com/t/ew72qd7Wp

Your second screenshot is revealing that both "admin" and "administrator" are domain accounts. The system administrator will not show up in that list of users...at least it does not on mine.
Are you positive that there is not another administrative account that was configured during the setup process? There really should have been, prior to even setting up a domain on SmarterMail.
