Briefly, we now use
metamta.default-address as the “placeholder” address in the “To” line for mail which only has “CC” users. You should configure this as some valid, deliverable address which does not bounce, because it is also used as the “From” address for at least some email, and users might “Reply” or “Reply All” to it. Ideally, this address should just accept mail that is sent to it and throw it away.
(We use a “placeholder” address so that users may write client-side mail rules which care about whether they were “To” or “CC” recipients and have them behave consistently.)
If you do not configure
metamta.default-address, it will default to
noreply@<meta.reply-handler-domain> if that option is set, or
noreply@<phabriator.base-uri> if it is not.
