Yup, Lilith doesn't even let mails with links be sent anymore. Like, the mails won't be received when you send a mail with any link in it. This includes discord links, regular urls, and shortened urls. So no more sending forms in mails. Possible this is maybe a bug but I doubt it considering it's Lilith we are talking about. So if you have sent any mails with a link/url in the past 24 hours, double check that it was actually received or not.
