The problem is, there is a lot that goes into operating an e-mail server on
the Internet. A small getting started book is not what we want out there, as
some one will take that and go and now we have another open relay or such on
the Internet.

 

What would be better is an article describing the items that a person needs
to be concerned with in summery, and the listing resources and suggestions
on each item for further research.

 

Some of the items:

 

1. DNS

2. Viruses

3. Domain name registrations

4. Relaying

5. Hijacking

6. User controls

7. Terms of use policy

8. Methods of connection

9. Security (This alone could fill a book.)

10. SMTP commands

11. Error messages

12. RFCs

13. The actual e-mail server operation.

14. If Exchange, Domain integration.

 

I do intend on creating this article as time permits, as I am heavily
involved in mail servers and all associated items. However, if some one else
wants to this, be my quest. I will be more than willing to help that person.

I know this is going to sound stupid, and probably already done...

But has anyone thought of writting a book to help people starting from
square one?

A small, simple book that says "If you want to host your own email and
website, read me" and explain apache + exim/sendmail and IIS + Exchange.

Also explain how to setup dns, purchasing website, etc.

I could imagine a small pocket book from oreilly like that... becuaes I've
met MANY people who want to do that.. but have no clue where to start.

I'll be the first to admit, when I got hired at where I am now, I had zero
server experiance and a small book like this would have been a god send,
versus learning the hard way (making the obviously stupid --hindseight being
20/20 -- mistakes).

Just a crazy thought...

If no one has written one, I think when I get off of work tonight, I'll
write up something short and see ya you peeps think (if your intersted).

Oh brother. You do not know what you are doing, do you?

 

1. If you are using the included Internet Connection Firewall that comes
with Windows XP and Windows 2003 server, you do not understand. You CAN NOT
USE THAT! That is a basic basic basic dumb firewall that is only a stop gap
measure.

2. Generally speaking, (unless you purchased the cheap version,) ISA 2000 is
included with Small Buisness Server 2003.

3. You are using a Linksys (what, DSL,) basic router that is not a firewall.


 

Some one needs to take some time and think about security.

 

Operating an Exchange e-mail server, or any flavor of e-mail server on the
Internet, REQUIRES dedication and understanding of the ramifications of
doing so. This includes taking basic standard security steps at the very
least.

 

For the Exchange server on SBS, disable the ICF and configure ISA server and
publish the Exchange server properly.

On the other client behind the Linksys, 86 the Linksys router, break down
and get a SonicWall TZ170 and configure the SMTP and POP3 protocols.

One is Win2k3 small biz srvr (Not ISA) built in firewall and the other
client has a basic linksys setup.
