You are saying you are running centos on a laptop, but don't know anyone running a "linux" computer. Do you mean that all the people you know are running Windows or MacOS? Or do you mean you don't know anyone with a laptop? Incidentally, I'm not running CentOS on a laptop, if that was your implication. I run Fedora (and Windows) on all the laptops I own. Most people I know have laptops and smart phones; only the youngest use their smart phones for email. > The main advantage of postfix > above sendmail is that it is now more common.

I changed because CentOS-6 changed to postfix as default, and I would generally follow the default on any system I was using. That does not alter the fact that the changeover was more difficult or at least more time-consuming than it should have been, due in my opinion to bad documentation. I don't agree with everything in <http://stevelosh.com/blog/2013/09/teach-dont-tell/> but I certainly think he is on the right side of the fence. > somehow I doubt that most families will start installing a centos server > to handle their e-mail.
