mailx -r not an option in Linux (return address)

I am porting scripts from Solaris to RHEL 5.x that contains mailx commands.  It looks like Linux does not support the -r for return address in Linux?

On Solaris, this works:
mailx -r -s "solaris subject"

but on RHEL 5, it returns:
mailx: invalid option -- r

Is there an alternative for a return address in Linux using mailx?  I would like to avoid changing all these scripts.

Try sendmail instead of mailx:

cat /path/to/body | sendmail -f
