Masquerade domain in IIS SMTP

Hi Guys

In IIS 6, there is the setting for a Masquerade domain for SMTP.

According to the MS article here;

http://support.microsoft.com/kb/303734

"The masquerade domain replaces any local domain name that is used in any Mail From lines in the protocol. The replacement occurs on the first hop only"

Let's say I have IIS running on a server named IIS1 - an SMTP relay.
An application on AppSvr1 is configured to use IIS1 as its SMTP server to send alerts.

Normally, the From: address will be alerts@appsvr1.domain.com

However, if I change the Masq domain on IIS1 to be IIS2, should the From: change to

alerts@iis2.domain.com?

Or does this only apply to the protocol MAIL FROM:?

I have tested, and it doesn't change either the header From: or the protocol MAIL FROM:

However, the MS article does state: "The replacement occurs on the first hop only"

So, does this mean the Masq domain only takes effect if the mail actually originates from IIS1?

Hello

the domain does not change the mail itself.
It only changed the HELO name in the smtp protocoll

instead of "HELO host.companyA.local" you can use "HELO mail.companyB.com".
