7. Comments

	1. General Results, most used to calculate the result
A	name "mail.noblemail.org" is subdomain, public suffix is "org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)"
A	Good: All ip addresses are public addresses
A	Good: No asked Authoritative Name Server had a timeout
A	DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
A	https://mail.noblemail.org/ 149.28.199.145			Good: Valid DANE - entry found: signed Data _443._tcp.mail.noblemail.org: CertUsage 3 (DANE-EE, Domain-issued certificate), Selector 1 (SPKI, SubjectPublicKeyInfo), Matching 1 (SHA2-256, 256 bit hash by SHA2), CertificateAssociationData: 4ee67315c685e3b6bca8e27d96ebd1a2b052cf6f0366de2eacaae75969d62cb5 confirms the Certificate with the same value
A	Good: destination is https
A	Good - only one version with Http-Status 200
A	Good: one preferred version: non-www is preferred
A	Good: every https has a Strict Transport Security Header
A	Good: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (2 urls)
	https://mail.noblemail.org/ 149.28.199.145			Url with incomplete Content-Type - header - missing charset
	http://mail.noblemail.org/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 149.28.199.145			Url with incomplete Content-Type - header - missing charset
A	http://mail.noblemail.org/ 149.28.199.145	301	https://mail.noblemail.org/	Correct redirect http - https with the same domain name
B	Warning: HSTS max-age is too short - minimum 31536000 = 365 days required, 15768000 seconds = 182 days found
	2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)
	3. DNS- and NameServer - Checks
A	Good: Nameserver supports TCP connections: 1 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 1 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
A	Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 1 good Nameserver
	Nameserver doesn't pass all EDNS-Checks: ns1.mail.noblemail.org: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
A	Good: All SOA have the same Serial Number
	Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.
	4. Content- and Performance-critical Checks
A	Good: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
A	Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
