Thanks
Since the "-s" option of the test command tests "FILE exists and has a size greater than zero"

The answer is not "! -s" but rather "-s" to satisfy the OPs needs.

Code:
if [ -s Schemaerr.txt ] 
then 
    cat Schemaerr.txt | mailx -s " SPEAR Error Log File!!!! " $MAIL_LIST
fi

or you can abbreviate this as follows:
Code:
[ -s Schemaerr.txt ] && cat Schemaerr.txt | mailx -s " SPEAR Error Log File!!!! " $MAIL_LIST
