Question : Configure SMTP settings

Having trouble getting the correct settings for smtp servers.

I have a web application the runs under two load balanced web servers.  Each server is running Windows 2003 Web Server and IIS 6.

I have set the FQDN in smtp server to "ultracamp.com" (the domain)

Here is a return response I recieved that is typical.

******************************
Return-Path:

It would seem there are two issues in the respone.
1. from unknown (HELO ultracamp.com)
2.  from "ucweb1 ([127.0.0.1])".....It really shouldn't show the computer name......should it?

I don't know what to do to correct this.

Thanks for your help.

Answer : Configure SMTP settings

1. it says unknown because can't lookup the reverse DNS.  I see that there is one and it matches your helo name.  Has it been there long?  Is it still doing this?

2. Yes it tries to make the email as traceable as possible. Your local SMTP service received it from 127.0.0.1 first and then relayed it.
