DNS opsætning E-mail

Der skal altid oprettes minimum 4 DNS opslag: 1x TXT + 1x SPF + 1x TXT + 1x TXT (se herunder):

1. DNS opslag nr. 1: Oprettes som TXT på dcgr.dk domænet:
   TXT:
   Hostname: pavo.dk._report._dmarc.dcgr.dk.
   Text: v=DMARC1
   TTL: 3600
2. DNS opslag nr. 2: Oprettes som SPF:
   SPF:
   Hostname: pavo.dk.
   SPF-Record: v=spf1 include:spf.protection.dcgr.dk –all
   SPF Mechanism: Fail – reject mail from other senders
   Additional IP addresses in CIDR format that deliver or relay mail for this domain: n/a
   But maybe You know additional IP addresses to put in (earlier mailgateway was one.com – must be in Your DNS, pls. look into that information and update accordingly.
   Any domains that may deliver or relay mail for this domain: spf.protection.dcgr.dk
   If You know additional domains to put in (earlier mailgateway was one.com – must be in Your DNS, pls. look into that information and update accordingly.
   TTL: 3600
   I TXT format ser den sådan ud (PS. Kan kun oprettes som et SPF, men editeres som et TXT)
   TXT:
   Hostname: pavo.dk.
   Text: v=spf1 include:spf.protection.dcgr.dk -all
   TTL: 3600
3. DNS opslag nr. 3: Oprettes som TXT:
   TXT:
   Hostname:  _dmarc.pavo.dk.
   Text: v=DMARC1; p=reject; rua=mailto:dmarc-report@dcgr.dk; ruf=mailto:dmarc-report@dcgr.dk; fo=1; sp=reject
   TTL: 3600
4. DNS opslag nr. 4: Oprettes som TXT (se pkt. 5 for yderligere info omkring dette punkt):
   TXT:
   Hostname: dkim._domainkey.pavo.dk.
   Text: v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAtN6vo9x/J+yNpTrIKNgtYtPb7uMgEwloPtCil8Mx3idvOfsPXl3YR2dLG3RoSpg2YqUN5ltRqeVfuMwDzRs6duBbm2hEFA06ii60R+WiTDDp10BZVO+4UKLmEbwFVDFMc5iOThx9tZclpZyPpO9fAdrBpM214DhVh/XgpIXrz9I2DmzBu67tF0fEo/N5B4lmbUPx3nQvBzQRARaXCypQteGkCTX+TspVQY3krBhemjJQzOcJCctsmJBa5p/iMGfc+1SlJsovcAgMLt/lIygwu2KOVSWG1MX3tmqSy3biNj9U6gQ7cUQXiZ0Wn8A8xcl3HbQy++mTY1iw0mRyh1Y8QwIDAQAB
   TTL: 3600
5. Tilføjelse af nyt domæne til at benytte DKIM
   Åbn C:\Program Files\Exchange DkimSigner\Configuration.DkimSigner.exe på EXCH-01
   Tilføj nyt domain under “Domain Settings”
   Domain Name: Valgfrit domæne
   Selector: dkim
   Generer en ny nøgle som opbevares i C:\Program Files\Exchange DkimSigner\keys på EXCH-01
   Opret ny domæne på EXCH-02 med samme private key som fra EXCH-01 opret her:
   EXCH-02: C:\Program Files\Exchange DkimSigner\Configuration.DkimSigner.exe
