Decided by the owner on 2026-10-13 (in place of preflight), taken up on
2026-10-16; mockups b2dcefc, cc33890, 0feaa55 (his: the greeting on a row
of its own, the name check a tag beside Names).
- The certificate: health.Certificate keeps its names (DNS names, or the
CN without any) and ForHost holds it to SELFPOST_HOSTNAME as a TLS
client does - VerifyHostname over the DNS names, the CN only without
any, as OpenSSL's X509_check_host and so a sending Postfix still take it
(src/tls/tls_client.c:439, 513). A certificate for another name fails;
the tag beside Names says matches / not for the hostname.
- The greeting: postconf -x -h smtpd_banner, read once at the panel's
start like the served certificate's path (main.cf is not rewritten
after), is what smtpd writes after "220 " (src/smtpd/smtpd.c:5979). A
first word other than the hostname warns, with what to set. A fact may
now take the whole row (Fact.Wide, sp-wide) and carry a tag beside its
label (Fact.LabelTag); both on the kit page.
- The proxy: auth.Module.Seen says the address the panel counts sign-ins
against, the peer, and whether X-Forwarded-For was read or left unread
for an untrusted peer; the Configuration card shows "Your address" and,
in the second case, warns that every visitor shares one sign-in limit
and names the /32 (or /128) to put in TRUSTED_PROXY_CIDR.
Tests: TestCertificateForHost (CN-only, DNS names, a wildcard, the CN
ignored beside DNS names), TestSeenAddress, TestHealthSaysWhereItSeesTheViewer,
TestHealthGreetingAndCertificateName; e2e reads the stand's right state on
Health (matches, "220 mail.e2e.test ESMTP", a direct client). go vet + go
test (26 packages) and make e2e on the test server for this tree.
Docs: help (word for word with the mockup), guide § Overview and Health,
CHANGELOG [Unreleased] § Added, roadmap row done.
