Consumers read `${bound:smtp:domain}` and `${bound:oidc-client:issuer}`, and both keys reached
them only because a module's settings were laid over everything it served. Issue 173 stops that: a
setting overrides a key a served fact declares and adds none. So the two providers declare the keys
their consumers read, as the operator's value (`${setting:…}`, ADR 0155), and the setting that
already carries each fills it. Nothing a consumer reads changes.
Merges first: under the controller that still merges settings over served facts this is the same
value, and the controller that stops merging (mesh-controller, feat/the-mesh-places-its-own-files)
needs these declared before it rolls out.
mailu
Mail — Mailu, with its provisioner (the smtp provision) and tools, on the tool runtime.
Settings
A definition names no mesh (novox/hq ADR 0112, ADR 0155), so the values that are this
installation's are settings on the assignment, settings set mailu <file>:
{"domain": "…", "sitename": "…", "website": "https://…", "proxy-address": "…"}
domain is the mail domain (also the provisioner's, for a consumer's address); sitename and
website are shown by the web front; proxy-address is what REAL_IP_FROM trusts a real-IP
header from — the address the proxy forwards with. The front's own hostname is the name of its
web route, told to it by the mesh.
