Why

A tester's ticket email landed in spam. I bought a demo ticket addressed to a mail-tester inbox (ticket HcKjnsk6kcqH2i4JVUQcbt): 8.3/10, SPF / DKIM / DMARC all pass through the mail.ariege.io → mx.ariege.io relay, so the server setup and the test@ local part are not the cause. Every deduction was in the message itself:

rule	penalty
`MISSING_DATE`	1.4
`HTML_IMAGE_ONLY_04` (a QR with almost no words)	0.3
`MISSING_MID`	0.1

Gmail/Outlook weigh a missing Date:/Message-ID: as machine-generated mail far more than SpamAssassin does.

What

build_ticket_email (extracted, unit-tested) sets Date, a Message-ID under the sender domain, and a From display name from lnbits_site_title.
Body gains event name, dates, location, name on ticket, ticket id and the door instruction (text + HTML), so the HTML part is no longer image-only.
config.json → 1.6.1-aio.9; docs/upstream-candidates.md row (lnbits core send_email has the same omissions → aiolabs/lnbits#71).

36 tests pass; black / ruff / prettier clean.

Deploy

Merge → tag v1.6.1-aio.9 → catalog entry → upgrade on demo → re-run mail-tester (expect ≥ 9.8).

A tester's ticket email landed in spam. A mail-tester run against demo
scored 8.3/10 with SPF, DKIM and DMARC all passing through the VPS relay,
so the deductions were all in the message: MISSING_DATE (1.4),
HTML_IMAGE_ONLY_04 (0.3), MISSING_MID (0.1) — and Gmail/Outlook weigh a
missing Date/Message-ID as "machine-generated" far more than that.

- `build_ticket_email` sets Date, a Message-ID under the sender domain,
  and a From display name from `lnbits_site_title`.
- The body now carries the event name, dates, location, name on ticket,
  ticket id and the door instruction, so the HTML part is no longer a
  QR with a handful of words.

Upstream candidate: lnbits core `send_email` has the same omissions.
