I planned to use a filtering/archiving service with my account, and I need Zoho mail's outbound IP address ranges so I can configure the filtering service. 

I found it once in FAQs or help docs or something, but I haven't been able to find it since. It'd be great if relevant address ranges were included with the help text under the admin control panel's 'outgoing mail gateway' config, so administrators don't have to dig through help docs and FAQs as much.

Thanks,

Chris
