Using the root account, I would like to send some routine emails to my users from the shell using a different default email so that if a user replies it does not go to root@myhostingdomain I recently changed from Fedora to Cent OS. I noticed the "mail" command in CentOS does not have to -r option that is available in Fedora. # man mail Is there a better way to do this?
You could do it with the php mail command. Set up a small php script that sends your mails then run it from the command line.
