Postfix?

[Ralphred]

I've been running sendmail myself for years, and am fine with it, but I have to set-up some new servers where I'm not the only maintainer.
There is a general consensus that postfix is easier to use, so I thought it'd be a good idea to use it in these cases instead of my default of sendmail, anyone know of a decent resource for someone switching?[/list]

The Postfix Documentation is very thorough with tons of examples.

It is ready to go almost out of the box if using a standard local machine and its accounts.

Rather than pointing to a porting guide, ask questions and those who are experienced can help (after reviewing any documentation first).
