I recently noticed this footer on email notifications from the Fedora Discourse instance:
Heads up: We send a maximum of 100 daily emails. Check the site to see the ones that might be held back. PS thanks for being popular!
Is this an intentional limitation? Is there still an expectation that Discourse will be used to emulate mailing lists?
EDIT I realized that when I got this warning, I still had trust level 0. But according to the documentation of trust levels, there should be no impact on email rate limits.
