Issue #19605 has been reported by znz (Kazuhiro NISHIYAMA). ---------------------------------------- Bug #19605: Please backport "Update how to subscribe mailing lists" https://bugs.ruby-lang.org/issues/19605 * Author: znz (Kazuhiro NISHIYAMA) * Status: Closed * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I think how to subscribe should update. Because sending mail to `ruby-dev-request@ruby-lang.org` causes `Address not found`. https://github.com/ruby/ruby/commit/8519d94d3d8511080d3724fd328926d443cb95fa -- https://bugs.ruby-lang.org/
