Not getting bug email

I'm subscribed to llvm-bugs and I get those messages. But, I'm not
seeing emails for comments added to bugs I'm cc'd on (e.g. PR24923).
I've checked my email preferences and AFAICT I should be getting them.
I've checked the two company-supplied filters I'm aware of and they're
not catching anything. is on my safe-senders

Anybody else having this issue? Can somebody suggest a remedy?

I’ve noticed that comments on bugs that I’m CC’d to end up in my inbox in gmail instead of filed away in my llvmbugs label. No idea why, but maybe that is a clue?

I’ve looked through every folder, checked my junk mail—they are nowhere to be seen.
