RE: SPF problem: was RE: Publishing an Exchange Server and email still going out through the default IP

Hi Ted,
Well here are a couple of setups
1.  When you publish exchange server in most instances you will be
publishing port 25 without the message screener.
2.  My adding only the smtp service on your ISA box you would publish to
that just like you would with exchange and now you can add the message
screener to the setup.

There are many options for setting up smtp and exchange. There are some
good
articles out on isaserver.org that address the setup issues.

Thank you,
Joseph

While you are on the topic, can you tell me how this is different from
publishing an Exchange server? What are the benefits of doing it this
way?

Hi Joseph,

True enough! There are several articles by moi on the ms.com and
ISAserver.org sites on how to configure the ISA firewall itself as an
inbound SMTP relay. No extra software, no extra hardware.

Relay servers can be located on the ISA box and in the DMZ on 
the web machine.  I have it setup this way and it works great and I'm
not using an extra machine.  However, I have used POSTFIX and sendmail
in testing and they work as well.

Thank you,
Joseph

That assumes the following:

 

*         That there is someone who knows linux

*         That there is an extra workstation

*         That they want another point of failure for email

*         That they want to spend the time configuring this

 

I just feel like this is a hack and it should not be this way. 

 

Might be out of luck huh....?

Can't they afford an old workstation, with freebie Linux, and one of the

many flavours of mailserver available???

Hehe - that is what I am saying... a relay server is not an option at

this point. 

 

I guess I am really trying to find out if there is any movement on this

issue at MS? Or will there be? I know this group would know if there

was... :)

 

Does checkpoint or other popular firewalls have this issue? I would

think the answer is no. 

 

This should be taken seriously considering the SenderID. Not every

company can afford to create relay servers in a dmz.

 

Thanks Tom for the reply.
