+What mailu's autoconfiguration module (automx2 2021.6, container mailu-automx on novox, Werkzeug/3.1.9 Python/3.9.5)
+answers to the requests mail clients make (R4d step AMX-1, issue 1630, ADR 0480).
+
+Captured 2026-10-21 between 13:58:25 and 13:58:52 (CEST; the Date headers said 11:58 GMT) with the mesh tool
+shanks/netcheck.netcheck_request, called from shanks, through the names clients use (autoconfig.novox.be,
+autodiscover.novox.be, automx.novox.be: HTTPS, the mesh's route), no ssh. A redirect is reported, never followed.
+Mail domain served: novox.be. Mailbox used: jochen@novox.be; unknown domain: nobody@unknown.example.
+
+Each capture is four files with the same stem:
+  <stem>.request   method and URL, then the request headers sent, then (after a blank line) the body sent
+  <stem>.status    the status line
+  <stem>.headers   the response headers, sorted by name, without Date (it changes on every request)
+  <stem>.body      the response body, byte for byte (Content-Length in .headers equals its size)
+The files were written from the tool's answers by a script (not by retyping each by hand); the tool returns JSON, so
+a later capture that wants exact bytes needs a tool that writes the answer to a file.
+
+What the answers show (read, not guessed):
+  - GET /mail/config-v1.1.xml?emailaddress=... answers 200 application/xml on all three names; same body on each.
+  - The incoming (IMAP) server has an EMPTY hostname (<hostname />), port 143, STARTTLS. The outgoing server is
+    mail.novox.be:587 STARTTLS. Cause (from reading the module, not from the database): automx/files/add-domains:35
+    reads AMX_IMAP_SERVER, files/mailu.env:58 sets AMX_IMAP_ADDRESS, so the IMAP name was never written.
+    A client given this answer cannot find its IMAP server.
+  - POST /autodiscover/autodiscover.xml with a valid request for the served domain answers 500 (the Outlook
+    answer for a real mailbox does not work today). Unknown domain: 204 no body. Malformed body: 500.
+    No EMailAddress element: 400 "Missing request argument "EMailAddress"". GET: 405 with Allow: POST, OPTIONS.
+    The path is case sensitive (/Autodiscover/Autodiscover.xml is 404).
+  - GET /mobileconfig?emailaddress=... redirects (308) to /mobileconfig/?emailaddress=...; for the served domain that
+    answers 400 with no profile; unknown domain 204; no emailaddress 400.
+  - GET / on autoconfig answers 200 with a small HTML page linking to an example address.
+  - Not captured: the database rows (no mesh tool reads /data/db.sqlite; issue 1630 AC4).
