    I have a webserver for hosting my own company’s various websites. The company default website was registered and is still hosted at another hosting company, and we have not yet changed that. That means the Hosting company (HostMonster) is handling the Certificates also for my company’s website and they also handle the DNS server. What I did was to create a new sub-domain on the default company website to be hosting.company.com and redirect this to the new server. On the new server (running Centos and cPanel) I have defined the additional websites. That means that this new server have no permanent DNS route nor has it a ssl certificate.
    On one of the sites hosted on this hosting server, we are getting a constant email problem:
    “Your access to this mail system has been rejected due to the sending MTA's poor reputation.”

    What can I do to resolve this and prevent it from happening again?

    You may want to figure out what reputation service the destination server is using, so you can contact them and figure out why they consider your server to have a poor reputation.

    It sounds like you are mixing and confusing two totally separate subjects ...

    However your mentioning the lack of DNS and the issue with mail rejections sounds to me like you may not have reverse DNS configured for your new server's IP address.

    In order to be able to send mail to most destinations these days, there has to be reverse DNS (PTR) record for your server's main IP address. In other words, the receiving mail server has to be able to resolve your server's IP address back to a valid hostname.

    PTR records are NOT normally setup at your server unless the IP addresses are registered to you (See WHOIS at http://www.arin.net) so you would need to contact whoever actually holds the IP number registration for the IPs allocated to your server in order to setup a PTR record in their own DNS servers.

    (This would normally be whoever provided you with your server or the data center where your server is currently be hosted. IE: whoever gave you your IP addresses when you setup your server)

    Just simply contact them and ask them to put in a reverse (PTR) record for your main server's IP address that resolves back to your hostname.
