I have in my /etc/ppp/ip-up (which gets started after the ppp-link is
established):
# See what's going on:
echo "Getting Mail for User freak..." > /dev/xconsole
# Getting Mail for freak:
su --login freak --command "/usr/bin/fetchmail --daemon 500 --all"
You could do something like
su - username -c "/home/username/.checkformail"
as well.

DON'T USE "xhost +"!
You can get things right with xauth, but I would recommend
you install ssh form non-us (or non-free?).
Then you can start a terminal like:
$ rxvt -title [EMAIL PROTECTED] -e ssh -l root localhost
^ optional ^shell ^login ^where
and you have no more problems with DISPLAY, xauth etc.
