Does anyone know how to change "From:" address in mailx command

[John Jimenez]

We send out files daily to an ftp server and email our customers using mailx. The subject of the email lets the customer know who to call back or e-mail, but the customers still try and "reply" back to these e-mails. I modified /etc/mail/aliases so I can re-route it if it is sent through our internal network, but since it is not a registered name the outsied world cannot resopn.
Does anyone know of a way to modify this field to a real e-mail address so that when someone clicks reply it actually finds a real e-mail address on out network?

John,

I don't know how to fufill your request with mailx, but I do have a sendmail script that allows you to punch in valid email addresses so that replies to the email go somewhere real.

I'm attaching it. Its poorly documented, but it works good. It's a mod of something I got from HP, so they are partially responsible for the lack of documentation.

Check out the '-r' option to mailx.

# mailx -s "test" -r from@somewhere.com to@somewhere.com


Will create a message to to@somewhere.com from from@somewhere.com I just test this on HP-UX 11i, 11.0 and 10.20 and it seems to work.

the -r option did the trick :) Thanks for the script too....
