Mailing list mode not really usable as is due to daily email limit

If you activate “mailing list mode” under Preferences>Emails and follow more than 1-2 topics/lesser prominent categories, you quickly get to see this:

“Heads up: We send a maximum of 15 daily emails. Check the site to see the ones that might be held back. PS thanks for being popular!”

This renders the mailing list mode rather useless, I’m afraid. Is it possible to increase this maximum by two orders of magnitude?

Thanks in advance!
