xenodm(1) sets the same standard environment variables as login(1) and
ssh(1) in the user session, except for MAIL. Users may expect to
receive mail notifications in X and miss them as a result.
Here's the patch to add MAIL to the environment.
As a side effect, it will enable ksh(1)'s periodic mail checks.
