My default shell is tcsh, not sh or bash, so /etc/profile should not
matter, but I'm pretty sure the environment is not the problem in
this case.  In any case, I tried the tcsh equivalent.  Same problem.

    ssh -t mydomain.com "source /etc/csh.cshrc; source /etc/csh.login; 
./junk"

If I add echo $status, I see that the piped mail command is returning
0 (success).

    #!/bin/csh -f
    echo "hello" | mail -s "Test" fred
    echo $status

If I echo $status after running the script, I see that the script is
returning 0 (success).

    ssh -t cloud1.balancedcomputing.com "./junk; echo $status"
