https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+subscriptions lists two subscriptions.

“Ubuntu Toolchain Hackers” team subscription: (unnamed)You do not receive emails from this subscription.

“Ubuntu Foundations Bugs” team subscription: (unnamed)
You will receive an email when any change is made or a comment is added.

The Ubuntu Foundations Bugs subscription should not be generating email to my address because that team has an email address of its own.
