I have a domain registered with godaddy.com, i.e. "hydammonia.com", I am able to send mails but not receive.
On www.dnsstuff.com i get a "Mail server host name in greeting" warning.

I am using Exchange 2007 on Windows 2003
FQDN (Send Connector) set to: ibmserve.hydammonia.com
ibmserve happens to be the name of the Machine where the mail server is hosted.

Go daddy Settings:

Set the mx record to ibmserve.hydammonia.com
Created an A record where "ibmserve" is pointed to 121.243.129.119
SPF Record created with the following text: "v=spf1 ip4:121.243.129.119 mx:ibmserve.hydammonia.com -all"


Should I contact my ISP to create a "Reverse Lookup record"
Do I need to create one in Windows 2003 AD, If yes then Would it be in the forward look up zone or the Reverse Lookup zone.

What is wrong. Please advice.

Exchange 2007 will always fail the Mail Server host name in greeting tests. I have explained why here: http://blog.sembee.co.uk/archive/2009/03/05/94.aspx

You should have a valid reverse DNS record for the server, which needs to match the FQDN setting on the Send Connector.

While you can create a reverse DNS zone in AD, it will not be used by the internet, so wouldn't make any difference.

Simon:

you mention valid reverse DNS record for the server, Where should I look for that and where should it be entered?

my FQDN setting on the send connector is: ibmserve.hydammonia.com

The reverse DNS is set by your ISP. You would need to use one of the numerous online tools to check what yours currently is. If you have never asked your ISP to set a reverse DNS record then almost certainly you don't have a valid one. The DNS Stuff tests should have shown you the reverse DNS setting.

Has Powershell sent you back into the Stone Age?

Ok. We informed the ISP that reverse DNS lookup needs to be created and mapped to ibmserve.hydammonia.com

We are able to send and receive mail.

However internet webmail services like gmail,yahoo route our outbound mails to their SPAM folders.

What should be done?

Has the reverse DNS address been setup?

Does your email look like spam? Content, signatures etc.
There is no magic fix to stop email being sent to spam folders. It can be a combination of things that causes the service to flag your messages as spam, and there is no definitive way of knowing what they are.

Yes.

Yes.

I have written an email to my isp (Relevant content pasted below) which is self explanatory:

================================================================================
2.      Our Outbound mails are still routed to spam folders of various webmail companies like "gmail" , "yahoo" etc...

3.      To trace the reason we did a "spam database lookup" @ www.dns.stuff.com and have pasted the URL below for your ready reference. A copy of the results is also attached in pdf format.

4.      One of The result of the above test reads as follows: TXT= "Your ISP TCISL Tata Communications/AS17908 is UCEPROTECT-Level3 listed for hosting a total of 6098 abusers. See: http://www.uceprotect.net/rblcheck.php?ipr=121.243.129.119


5.      When we raised the topic in one of the forums as "Unable to send mails to gmail". We got the following reply from one of the senior members:
There is nothing you can do about this.
Your provider is on a level 3 list at UCEPROTECT.
Basically your provider has been blacklisted as a source of spam.
Google are therefore rejecting direct email messages. You will need to route email through your providers SMTP server using a Send Connector and a smart host.
6.      We hence wish to know if "Tata Communications Ltd" is able to provide "Smart Host" facility to its client. If yes, Then Please provide the details to configure the Smart Host like SMTP Server details, Relevant IP address, etc..
7.      We would then be able to configure our mail server to route mail through your "SMTP Server" and SPAM would not be of concern anymore.
===================================================================================
I am awaiting their reply probably by tomorrow.

Unfortunately My ISP doesn't provide "smart host" feature. So I have switched to godaddy's webmail with the same domain for now. thanks.

I have subscribed to dynDNS's Mailhop OUTBOUND services. I am using their "smart host" on my exchange server 2007. Things are working fine now.
