Thanks for getting back to me.

But how do we know if Junk mail filtering has been disabled in the first place for us to check? Do we get some sort of notification?

For that matter, let's say it does get disabled and the user count issue is rectified immediately - do we have to wait 5 days before we can enable the junk mail filtering switch again?

Is there an actual page which describes this all in detail and how it works..? The site here doesn't explain it very well: http://xeams.com/XeamsCost.htm

Thanks guys.
