test / test (push) Canceled after 0s
Follows the design commit before it.
- internal/dmarc: the ingest allow-list is the report address of each
domain that is on this host and nothing else;
DefaultHostedReportAddress and DefaultHostedSuggestion are removed.
Since 1.7.0 the general mailbox dmarc-reports@<hostname> was open
while no panel-wide default existed; the three-choice scheme had
left it open always.
- The DMARC hub's Ingest box shows the form of a hosted address,
dmarc-reports+<domain>@<hostname>.
- guide.md: what port 25 accepts.
Evidence: docs/assets/panel-redesign/evidence/dmarc.png re-shot (the
address form wraps after the plus sign in its column at 1440 px).
