Date: 2003Jul18 Updated: 2019jul25 Product: sendmail Q. Linux: How do I do *something* with Sendmail? A. I gave up on sendmail a long time ago. I now use Postfix http://www.postfix.org. I have also heard good things about Qmail http://www.qmail.org Postfix was originally written by a guy at IBM and is GPLed. A rpm is now included with RedHat/Fedora/CentOS -- but I used it before it was.
