Oops, I see now that the mailx on RHEL5 and RHEL6 and very different beasts. RHEL5: mailx-8.1.1-44.2.2 RHEL6: mailx-12.4-7.el6.x86_64 http://heirloom.sourceforge.net/mailx.html The legacy mailx on RHEL5 doesn't support all those options. If it's acceptable in your environment, you can get the newer "Heirloom" mailx from the EPEL repository. Note that it's the "nail" package on EPEL.
