use 'su -'.  It means you get a login shell (which sets up the enviroment
in the same way that login does).

I expect you can do the same thing with sudo with something like
'sudo bash -login' or similar.

The extra things the shell does when running as a login shell; in
particular clearing the enviroment and setting things like LOGNAME
and USER (which I expect /usr/bin/mail and others pay attention to).
