It should work fine for people that use fetchmail to download their

commercial accounts.

So you don't think RH and fedora are suitable distributions for people
with commercial accounts? I can understand that for fedora, but all RH
based distros are broken the same way.

Not what I said at all. But no configuration is going to be "right"
for people with commercial accounts.

It has been a long time sense I
has able to use a stock Sendmail, or Postfix configuration file
regardless of the distribution.

That's my point... Why not ship something that works?

Works for who? There is no "one size fits all" configuration. The
configuration I use is not going to work for you. How may people
would your configuration work for? Regardless of the configuration
shipped, most people with a commercial Internet connection are still
going to have to modify the configuration. Chances are, people with
a small network are also going to have to change it. The stock
configuration will work for stand-alone machines, and is fairly safe
to run on a network machine.

To fully integrate the mail server into the network, you are going
to have to do some network specific modifications in just about
every case. The days when a mail server could send mail to any other
mail server without specific configuration are gone. If you are a
non-commercial user, chances are you have to relay though your ISP's
mail server. You may have to do the same with a small commercial
network. With just about any network, you have to set up who can
send mail through the server. You may also need to change how your
mail server announces itself over the Internet. You may also need to
route all outgoing mail through one server, and you may need to
route internal mail to another server.

What about the people that have their primary mail server at their
hosting service? Are they relaying their outgoing mail through the
same server? If so, you have to change the configuration to use that
host as a relay. If you are not relaying through the hosting server,
do you have to relay through your ISP's mail server? Or does the
server have to masquerade as another host when sending mail over the
Internet?

At one time or another, I have configured Sendmail and/or Postfix to
handle all of these setups. I have tweaked the sendmail.cf files, as
well as used M4 to create new ones. I also tent to tweek the config
files of other services to work the way I expect. I am in favor of
shipping servers with configurations that are as secure as possible,
and the services turned off by default. Most systems need a mail
server running, so having it only accept mail from the local machine
in the next best thing to not running it.

If the other services didn't work as distributed you probably
wouldn't run them either.

All I can say is do a Google search on me. Some of the hits with the
ExecPC email address show how much things have changed over the years.
