Configuring the Default Domain to login to.....

[Guest]

Since I really only run 1 domain, is there a way that I can make is so my users just have to type in their name and not full email address?

Definitely:
there is an option in the toaster-watcher.conf:
vpopmail_default_domain        = 0

change 0 to your domain, exampe.com or whatever your domian is.

I'm moderately sure you'd have to recompile vpopmail after making that change.

You'd have to run

 toaster_setup.pl -s vpopmail
