Is possible. The manuals explain how, it's programmatic anyhow...
An alternative is to use the mail client (Outlook?) which is already on his workstation, and call the MAPI interface from the IIS 5 application. This will pose a _lot_ less security risks than installing the SMTP service...

Bad idea. This opens up security problems on his machine and presents the possibility that the user may engage in spamming. No network admin worth his salt would allow something like this.

To clarify the question:
Is he the boss? - explain danger of him having the service and do what he decides
is the user bend on using SMTP?
if yes you could install it relay mode to your local smtp. ( microsoft or a freebie from www.pegasus.com )otherwise you would allow him to email without any spam control.

Is a programmer or tech ( or at least he thinks so ) and wants to test sepcifically the IIS5 SMTP?

You have already made a decision to install it and run but need help setting it up?

wants to open realy server for all his buddies in you CORP?

You need clear instructions on how to scare him to not to do it?

Hi there,

From your statement, I would assume that he wants to have a mail server running on his machine, if this is not what you meant then below is irrelevant.

Consideration
-------------------------------------------------
1.Machine capability
2.Who is going to maintain the machine in future?
3.Security concern
4.Does he want backup features for the mail server?
5.Definately need a AntiVirus SW running in the machine for email scanning (ex-Scanmail:trendMic)
6.Anti-spamming and anti-relay configured

Question
-------------------------------------------------
1.I would assume that you have existing mail server running in your network, right?
2.Do you have a DNS server running internally? Is it a primary one or secondary?

Answer
-------------------------------------------------
Fulfilling this requirement is not difficult but it's just that Im not too sure what environment you are running in your network. (Ex: DNS serv - p/sec dns?, SMTP flow in your network,etc)
Anyway, after installing the necessary application, which ever he chooses. Assuming he
is using his own domain for email.

You'll need to inform the ISP to update their DNS
to point to this new domain of his.
If you are hosting the secondary, update the MX records and make the zone transfer with the primary one in ISP.

Next, map a routable IP to the his machine IP which is the internal IP (non-routable IP). If you are running a FW (any FWs), do the mapping there and have the policy defined for SMTP purpose.

Remember to have the Antivirus installed or else
there's no point to even have a MailSrv running plus disable the anti-relay on the machine. This to make sure that he's not blacklisted for spamming.

I would assume from your statement that he wants
privacy for his emails (reason for his requirement). Therefore this is pretty simple as if having to install a new mail server in your network using a different domain. Hope the above concept helps you. As for configuration wise, I'll leave it to you as that can be found on the net.

Thanks
