Hi,
How many Apple ID do you have ?
I am not sure if this is relevant yet as I have server myself and I am not getting them appearing in Messages at the iMessage Account spot.
The Only way I know to get an Account into Messages (for the iMessages bit) is to
1) set an Apple ID the first time you launch Messages as part of trhe Set up
2) adding a second or third ID so you can changes your iMessages login.
I am not aware that Messages pulls any info from anywhere to use it as the iMessage info
(It can be different from the iCloud ID in System Preferences > iCloud (And of course Mail, Contacts and Calendars)
Mine does not even "swap" between the Apple ID it is and the iCloud one it was used to create.
Could you show us pictures ?
