Generally, there are two things you will want to do (broadly):

1. Use your own Domain Name Server and Configure It.

If you have a dedicated Domain Name Server (i.e., you're not using your host's DNS), you should be able to change Domain Name records for your domain (i.e., domain.com). Each DNS control suite is really different -- WHM, for example, has a dedicated automated system for parsing each entry that impacts the various exchanges of your domain. Learning the domain name system configuration syntax of your Domain Name Server is essential if you want to alter aliases or exchanges so that they maximize SEO and minimize Blacklisting. Check with your Registrar and your individual dedicated hosting company if you're not familiar with this process.

2. Configure your Sender Policy Framework.

Once you are able to alter records for your Domain Name Server, adopt one of the standards of compliance (such as OpenSPF or ReverseDNS) to properly identify your server's machine and prevent it from being blacklisted by major spam tools. You can Google these for some introductory documentation on setting up policies that direct robots and ensures it is properly being identified.
