Hello,

New to this list so i'm not sure if this is supposed to be submitted elsewhere.

The attached patch adds a configuration option so several domains can be specified in the login screen in the form of a drop down box.  The domain the user chooses will then be attached to their username to form their full email address. 

This is useful for IMAP servers that host many domains and the full email address is needed to login.  Tested this pretty throughly....

Thanks,
Stephen Blackstone
