Configurations Required for Email Server to avoid mails going in junkmails.

Hi Experts,

I have started a Exchange Server for a small company which has around 30 employees.
Exchange Server is hosted in Datacenter with one static IP address. This IP address will be used to send mails.

I have checked this IP address with various blacklist IP sites and confirmed this IP is not blacklisted.
I have also updated the PTR Record of this IP addres to the domain name which will be used to send mails.

Any other configuration required to reduce the chances of mails going in junk box?
Do I need to register with any service or something?

Any help will be appreciated.

Having a ptr record is one good step in making sending emails out successfully to all organisations, as most of the companies use that as a mechanism to fight spam.

Which version of Exchange?

I am using Exchange 2007.

Exchange 2007 is secure by default.

Check your domain in http://www.mxtoolbox.com/diagnostic.aspx to see whether you are an open relay, whether the ptr record is all working properly etc.

You can install the anti spam agents on exchange 2007 hub server


Apart from that, have a good AV on the server, use an edge or another spam filtering solution if possible.

Make sure your PTR is non-generic looking:




Make the MX record match the PTR record. Also make the banner (HELO address) the same as the PTR and the MX.

Add an SPF record for your domain. It'll let other systems know what IP addresses should be sending mail from your domain. Not everyone checks these, but it will only help.
