Thanks for the suggestion! Similar functionality was implemented in SmarterMail 15.x. Check out its announcement from the New Features in SmarterMail
For enterprise organizations, Web hosts or ISPs -- or any business, really -- that manage multiple mail server installations, keeping spam settings consistent across those servers has its challenges. SmarterMail 15.x makes it easy to use the same set of antispam rules for all of the mail servers across your organization.
This is because all global spam settings are now contained in a single XML file. That means you can configure a solid set of antispam rules on one server, then easily move those settings over to any additional SmarterMail servers you have running simply by copying over your antispam XML. As an added bonus, email administrators can even work together to create and share their antispam XML files files, combining their experience and understanding to create the most reliable settings available. Those files can then be easily uploaded to any SmarterMail server, right from the Web interface!
In addition, SmarterMail 16.x has an entirely new architecture that is 100% API-driven! That means that EVERY aspect of SmarterMail, moving forward, will be exposed via web service calls, allowing companies to build upon our platform however they want. Anything will be possible, including the ability to monitor all servers and push spam configurations amongst those servers.
