I use diald to do the automatic dialing for me.  Others use the
demand dialing option in pppd.  You need pppd versions greater
than 2.3.0 for this to work.  If you have an older version of
pppd, you will also need to patch the kernel and recompile a
new kernel.  You need to read the documentation included in
the pppd source file archive.

I think diald gives you more options for controlling what will
bring up the link to your ISP.  It also is slightly harder to get

Procmail is probably the software to use.  It is probably integrated
into your /etc/ as a mailer.  If so, you just need to set
up a .procmailrc file in your home directory.  There are all kinds of
things you can do with it to filter email.

If it is not called through through your /etc/ file, you
can rebuild a new one with it included or place a .forward file in
your home directory to call it.  The man pages explain this.

I have three machines networked together.  The Windows 95 machine
has Eudora Light on it which we use to write our email with.  Once
we send it out, it goes to my Linux machine where it sits until a
link to my ISP comes up.

In my /etc/ppp/ip-up file, I start fetchmail as a demon to check for
email every 5 minutes.  From the same file, I issue the command
"sendmail -q" to send out any queued email to my ISP's mail machine.

When starting up sendmail when the Linux machine starts, I issue
the command "/usr/sbin/sendmail -bd -q."

The file that I have used to generate a from
is shown below.  You may or may not need or want all of these.  Like
I mentioned above, I want sendmail to just accept the mail and hold
it until I bring up my link.

define(`confSERVICE_SWITCH_FILE', `/etc/service.switch')dnl
define(`SMTP_MAILER_FLAGS', `e')dnl
define(`SMART_HOST', `smtp:[]')dnl

My login name on my local machine is different than the one at my
ISP.  That is why I have the genericstable set up.

Hope this is of some benefit.

1. Which Linux OS best for beginner to setup as Web / Mail server / Internet sharer and firewall?

We are a small business with no IT employees and have about 20 Windows
ME machines.  None of that is subject to change.  We are installing a
DSL line, and when we do, we want to improve the way our Internet is
handled.  I am planning to try to set up a server which the DSL will
connect to, and will run our web site off the server, as well as
automatically get our POP3 emails from our outside accounts, and hold
them until our local computers want to see them.  It should also share
the internet connection and run a firewall.

We are only considering no cost versions of Linux for this purpose,
and we were planning on running either Fedora or White box enterprise
Is there any other no cost Linux that you would suggest would be
easier for an absolute beginner (no Linux experience at all) to set up
this type of a server on?  I know there are specialized mini versions
of Linux that only act as sharers and firewalls, etc., but I believe
that we will need the flexibility of a full linux to support future
expansion as well as the 4 features I mentioned, HTTP Server, POP3,
Firewall, and Internet sharing.  Feel free to point out if you believe
there is a better solution.  Also, can Linux speak to most DSL modems,
or at the least, can most DSL providers come up with something that
will speak to a Linux system?
