    The following is the command issued by root that works every other time:

    echo "This is a test mail"|mail -v -s "this is the subject sendmail opgeorge root server c" msulliva@northshore.edu

    Success for Attempts 1,3,5,7,9 etc (the relay happens and I am emailed)

    Failure for Attempts 2,4,6,8,10 etc (the relay does not happen and I am not emailed)

     

     

    Log when command works
