Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

mailx: invalid option -- r
Usage: mail [-iInv] [-s subject] [-c cc-addr] [-b bcc-addr] to-addr ...
[-- sendmail-options ...]
mail [-iInNv] -f [name]
mail [-iInNv] [-u user
Does anyone knows what's happening? thanks,
Yep...that option hasn't been supported for some time now. The mailx documentation is thorough, but complex. You've got a couple of options:
mailx -s "Subject" firstname.lastname@example.org -- -f email@example.com < body
The double-dash tells mailx not to parse the -f, but just pass it along to sendmail/postfix, which will then set the "from" address accordingly
The -a switch, which supplies additional headersy, supplying a From: header on the command line that will be appended to the outgoing mail. In conjunction with the $REPLYTO environment variable specifies a Reply-To: header:
Hate to disagree with you, but mailx on my Centos 6.3 supports it (-r ) fully. Its both in the man page and it works; just tested it to be sure...
Huh...I had read it wasn't supported, and it doesn't work for me on my system. However, from the man page:

Tilde escapes are disabled. The -r address options are passed to the mail transfer agent
unless SMTP is used. This option exists for compatibility only; it is recommended to set the from
variable directly instead.
The bolded part is what caught my eye. I'm puzzled though, since the man page DOES mention the "-r" being a valid option, but it does note it's only there for compatibility.
Well, your profile says RHEL+Centos; try it on one of those?
Yep...tried it on an RHEL6 server, and it didn't work, which is why I'm puzzled. Is the mailx executable on your box a link, or the actual mailx program?? I've seen links to "mail" from "mailx" before...but just grasping at straws here.
