DNS record of your server not the Active
Directory name you give your server when building?

-------------------------------------------------------Hello Supreet,

1. Make sure your MX record is the public IP of your mail server and not
ISP's DNS.

If your ISP hosts your DNS for you, you can ask them to make this
change, they will be more than happy to assist you. If you host your DNS
server, you will need to make this change. 

2. Ensure that your Exchange is advertising as the FQDN of your domain
when advertising HELO during SMTP transaction.



1. Open Exchagne System Manager. Navigate to Administrative Groups,
Site, Servers, Servername, Protocols, SMTP, Default SMTP Virtual Server,


2. Highlight Default SMTP Virtual Server, right click properties. 

3. Go to the Delivery Tab, and click Advanced Button.

4. In the "Fully-qualified domain name: field, enter your fully
qualified external domain name of your server for example
mail.yourdomain.com Click Check DNS to verify that it resolves. 

5. Restart SMTP service. 


If anything is unclear please ask.

-------------------------------------------------------Hi janes

I am posting here the errors of dnsreport.com. Please
have a look and suggest if there is any problem with
the configuration.

WARN Mail server host name in greeting WARNING: One or
more of your mailservers is claiming to be a host
other than what it really is (the SMTP greeting should
be a 3-digit code, followed by a space or a dash, then
the host name). If your mailserver sends out E-mail
using this domain in its EHLO or HELO, your E-mail
might get blocked by anti-spam software. This is also
a technical violation of RFC821 4.3 (and RFC2821
4.3.1). Note that the hostname given in the SMTP
greeting should have an A record pointing back to the
same server. Note that this one test may use a cached
DNS record.

mail.mydomain.org claims to be host mail.myisp.com
[but that host is at 11.11.11.11 (may be cached), not
22.22.22.22]. 
 
our MX is pointing towards (22.22.22.22 ), which is
the IP of ur ISP. As we have taken some storage space
from them.
