mix f62fe23826 release: 1.1.0: Domain-admin role and internal/web package split
The first MINOR after 1.0.0: send-only DMARC guidance in the panel, AGPL packaging on every page, and an internal split of `internal/web` ahead of domain-admin work. Upgrading runs one SQLite migration (empty defaults; existing DNS guidance is unchanged until you set a report address).
Changed:
  - `internal/web` split into subpackages (`web/view`, `web/auth`, `web/validate`,
Added:
  - panel: DMARC guidance for send-only relays — the suggested `_dmarc` record
  - AGPL packaging hygiene: [NOTICE](NOTICE) names the copyright holder and the
  - [docs/roadmap.md](docs/roadmap.md) — candidate item **visual-style** (panel

# Plan: dmarc-reports
**Status:** candidate
---
## Goal
SelfPost **receives** DMARC aggregate reports on SMTP, parses them inside the
image, and **shows summaries in the panel** — pass/fail by source, hints when
`tighten p=` is reasonable. No external DMARC SaaS and no IMAP workflow for the
operator.
## Scope
**In:**
- Inbound SMTP for configured report addresses only (not a general backup-MX).
- gzip + XML aggregate parsing → SQLite summaries per sending domain.
- Panel page and/or per-domain section: recent reports, third-party senders,
delivery health of report ingestion.
- Reuse `admin.dmarc_report_email` and `domains.dmarc_rua` for DNS templates;
when enabled, suggest a SelfPost-hosted report address.
**Out:**
- Forensic reports (`ruf=`).
- Full dashboards, APIs, email alerting.
- Mailboxes for people (IMAP/POP3/webmail).
## Architecture (sketch)
1. Receiving MTAs → SMTP to SelfPost (hub MX).
2. Postfix virtual alias or dedicated listener → panel ingest worker.
3. Parse XML → `dmarc_reports` table (domain, reporter, counts, date).
4. Panel reads SQLite; links from domain DNS card.
May share port-25 plumbing with [inbound-relay.md](inbound-relay.md) but must
remain a separate, opt-in feature that does not forward mail upstream.
## Done when
- Operator can point `rua=` at an address SelfPost accepts and see parsed
summaries in the panel within one reporting cycle.
- With the feature off, outbound-only behaviour is unchanged.
- Documented in [guide.md](../guide.md); migrations are backward-compatible.
## Risks
- Attack surface of accepting mail (mitigate: strict recipient allow-list).
- Report volume and retention (mitigate: caps + pruning).
