I am able to do it as below.

also make sure the email functions are installed on the cluster you are trying to run mailx command

#move the S3 file to local DIR on AWS
s3cmd get S3:attach.txt /tmp/attach.txt

#send the email with attachment
mailx -r test@test.com -a /tmp/attach.txt -s "TEST Subject" "test@test.com" << EOM

TEST body
