How set the From email address for mailx command?

Question

I am working on a KornShell (ksh) script running on a Solaris server that will send out an email when and error condition is met. I am sending the email via mailx.

Question: How to I set the "From" email address on the mailx command?

Current Code:

echo ${msg_txt} | mailx -s "Script Failure" ${to_email}

Note: The command works fine, however, the "From" is the name of the user I am running the script as and I would like for this to another email address.

How would I accomplish this?

Answer 1

The "-r" option is invalid on my systems. I had to use a different syntax for the "From" field.

-a "From: Foo Bar <[e-mail]>"

Answer 2

mailx -r [e-mail] -s ...
