- Read new config help.
Then did a bunch of testing, primarily with `bin/mail list-outbound` and `bin/mail show-outbound` (to review generated mail), `bin/phd debug taskmaster` (to run daemons freely) and `bin/worker execute --id <id>` (to repeatedly test a specific piece of code after identifying an issue).
With `one-mail-per-recipient` on (default):
- Sent mail to multiple users.
- Verified mail showed up in `mail list-outbound`.
- Examined mail with `mail show-outbound`.
- Added a project that a subscriber could not see.
- Verified it was not present in `X-Phabricator-Projects`.
- Verified it was rendered as "Restricted Project" for the non-permissioned viewer.
- Added a subscriber, then changed the object policy so they could not see it and sent mail.
- Verified I received mail but the other user did not.
- Enabled public replies and verified mail generated with public addresses.
- Disabld public replies and verified mail generated with private addresses.
With `one-mail-per-recipient` off:
- Verified that one mail is sent to all recipients.
- Verified users who can not see the object are still filtered.
- Verified that partially-visible projects are completely visible in the mail (this violates policies, as documented, as the best available compromise).
- Enabled public replies and verified the mail generated with "Reply To".
