We recently shipped mailing list support — and what looked like a straightforward feature turned into a deep dive into DKIM signature mechanics and DMARC alignment. This post covers how we built it, the problem we introduced, and how we fixed it.
KaiMail now supports mailing lists on your own custom domain — public forwarding lists, broadcast newsletters, and member-only discussion lists, all with proper DKIM signing and DMARC alignment. No separate tool required.
