Don't Forget to Bounce Sendmail

By barneyb on April 26, 2009

When you change the hostname of your computer, you need to do two things: add a local alias to Sendmail's config and restart sendmail.  I'm pretty sure I've forgotten step two every time I've set up a new box, and my new server was no exception.  Fortunately, I finally remembered that that was the problem this morning, and now it's forwarding local mail like a champ.

    I'm not sure I follow. Did you change the host name of an existing box, or setup a new box and forward from the old to the new? Also, just curious, what flavor of Linux are you running? Thanks!

    I got a new box, and changed it's default name ("centos4892837″ or something) to "cari2.barneyb.com". I'm running CentOS 5, though I've had this exact problem with pretty much every box I set up.
