I earn a living with building and deploying Internet system on a
variety of (Unix-based) platforms. Each one has its quirks and to
build successful servers, you have to know about them. I never ever
deployed a sendmail.cf as it came from the vendor or the source
package. I adjust these config files to the customers' need.

THERE IS NO SUCH EFFORT. This list is not your general-purpose Linux
support list.

If you need support for a distribution, get it from the vendor. If you
make a distribution, that deploys a software, give this support or buy
it from people who _know_ and sell it to your customers.

But this list is not for your "I don't have a clue" efforts. Deploying
a distribution is major grunt work that most customers will never see.

I e.g. deploy a highly customized version of RedHat on the servers
that I build. Most of my customers ask a second and a third time why I
don't simply deploy the distribution out of the box like all the
consultants that they had before. They stop asking when their old
boxes are cracked open or fail under load and mine doesn't. If you
deploy a general purpose distribution or OS for a very special
application, then you simply use the wrong tool.

Your distribution will simply have "RefuseLA" and "QueueLA" higher
than the sendmail defaults. This is not the solution to your problem
but moves it simply to a different point.

You simply don't understand, that a cluster mail system that handles
20,000,000 mailboxes and 200,000,000 mails per day must be configured
different than the mail system on a high traffic web server, that
simply sends out two mails per day from the logfile rotation. Both
machines may have a load average way beyond a desktop system that
peaks at 0.05 on normal usage.

Linux has no problem. Some sites that run Linux have a problem because
they're misconfigured.

And if you ship a distribution but want to load off the support for
this distribution on Linux-Kernel, you're definitely in for a
surprise. TANSTAAFL, you know.
