Requirements Message Security

1Requirements Message Security

1.1.1For Inbound Mail Filtering (messages received by your users)

Domain

You must have your own domain name for your email, not a shared or third-party domain. For example, your email address should be similar to your_name<em>your_domain.com</em>, not <em>your_name</em>hotmail.com.

Access to MX Records

You or your email administrator must be able to change your DNS MX records (used to direct your mail flow). If you own your domain, you should be able to change your MX records by working with your domain name provider or ISP. Our activation instructions will walk you through this process.

Mail Servers and Service Providers

Supported Mail Servers: The service supports all common mail servers, including Microsoft Exchange Server, Lotus Domino, Postfix, Sendmail, Macintosh OS X Server, and Novell Groupwise.



Supported Service Providers (hosted email): The service is also compatible most ISPs and domain name providers that host the email for your own domain. The service is not compatible with providers that don’t release mail server information, or don’t allow you to change the MX records with their hosted email service. Currently known providers that are incompatible with the service include 1and1.com and XO Communications.

Google Apps: The Message Security service is not recommended for use with Google Apps Standard as outbound filtering is not supported. We recommend you consider Google Apps Premier, which includes Message Security and Discovery, powered by Postini.
