I also got the same problem after upgrading Build 9 on my servers some of my mail domains are not listed under Tools >> mail manager .. but I gave them my server access and they fixed it. now its working fine.. :)

I was planning to install the latest build in my servers. Glad, that I did not do it and visited this forum. I would rather wait for the day when all the existing HC users will say the bugs are resolved.

Why you don't change the build date on the download page? looking there seems nothing is changed cause the old build date.
 
 

As it is the actual release date of build9.
