Hostname Resolution


I have dedicated server with os=RHE, plesk 8.0
The whole emails from my domain name are going into bulk and hotmail is not even accepting my mails. This is very new server and even the website is under testing process i.e. not yet launched. I contacted the hosting company they recommended the following: please help me to let me know how can I do that?

thanks & best regards

Most major mail providers require that the hostname of the sending server resolve back to the IP address that the mail is being sent from.

Your servers hostname is

[root@serverName ~]# hostname
servername.com
[root@serverName ~]#

While at first glance this hostname may appear valid, it is not, since it does not have a valid subdomain. You'll need to change your hostname to a fully qualified domain name that uses a domain that you own and control DNS for.

Example: server123.yourdomainname.com

Additionally to this, you will need to add an A record for the hostname in the domains DNS. Using server123.yourdomainname.com as an example, you would need to create an A record in the dns of yourdomainname.com for the server123. subdomain.

Another reason for choosing a subdomain.domain.tld format hostname, is that the mail transfer agent will not correctly process the domains mail if the hostname does not have the subdomain.

Not a 100% sure what your asking but I think your having a problem with name resolution because emails are not getting to outside sources.

They are asking you to find the Fully Qualified Domain Name for the server. On your mail server open the command prompt and type in "hostname" (with out quotes) and press enter. What does it return?
