We're running WHM 9.9.8 & cPanel 9.9.8-R160.
Today, I discovered the following default mail address problem.
When you set the default address to :blackhole: or :fail: no such address here, messages to the admin user will either not get delivered (in the case of default address set to :blackhole: ), or will bounce (in the case of default address set to :fail: ). Messages sent to other mailbox users on the domain are fine, it's just messages to the admin user which fail.
Has anyone else noticed this problem? This is on RHES.
I've tested this problem on three servers, all exhibit the same wrong behavior.
