Leer hoe u uw SPF TXT-record structureert voor correcte e-mailauthenticatie." image: "https://autospf.com/images/og-default.png" canonical: "https://autospf.com/nl/spf-record-formaat/" --- Complete referentie # SPF-recordformaat Een complete referentiegids voor het formaat van het Sender Policy Framework-record - mechanismen, kwalificaties, modifiers en praktijkvoorbeelden zoals [een voorbeeld van een SPF-record](/nl/spf-record-voorbeeld/) dat u kunt kopiëren. Conform RFC 7208 Recordstructuur ## Anatomie van een SPF-record `v=spf1 ip4:192.0.2.1 include:_spf.google.com -all` v=spf1 Versie ip4:192.0.2.1 Mechanisme include:... Mechanisme \-all Kwalificatie + catch-all Bouwstenen ## Mechanismen Mechanismen bepalen welke servers zijn geautoriseerd om e-mail namens uw domein te versturen, en ze komen voor in alle [SPF-recordtypes](/blog/complete-guide-to-spf-record-types-6-variations-explained-simply/). Elk mechanisme telt mee voor de limiet van 10 DNS-lookups (behalve `ip4`, `ip6` en `all`). | Mechanisme | Voorbeeld | Beschrijving | DNS-lookup? | | ---------- | --------------------------- | ------------------------------------------------------------------------- | ----------- | | ip4 | ip4:192.0.2.0/24 | Autoriseer een specifiek IPv4-adres of CIDR-bereik | Nee | | ip6 | ip6:2001:db8::/32 | Autoriseer een specifiek IPv6-adres of -bereik | Nee | | a | a | Autoriseer de IP-adressen uit het A-record van het domein | Ja | | mx | mx | Autoriseer de mailservers uit het MX-record van het domein | Ja | | include | include:\_spf.google.com | Verwijs naar het SPF-record van een ander domein | Ja | | all | \-all | Catch-all-mechanisme - komt overeen met alles dat niet eerder is gematcht | Nee | | exists | exists:%{i}.spf.example.com | Controleer of er een DNS A-record bestaat (gebruikt in SPF-macros) | Ja | | ptr | ptr | Reverse DNS-controle (verouderd - niet gebruiken) | Ja | Actietypes ## Kwalificaties Kwalificaties worden voor mechanismen geplaatst en vertellen de ontvangende server welke actie hij moet ondernemen bij een match - de kern van [hoe SPF uw domein beschermt](/blog/what-spf-records-are-and-how-they-protect-email-domains/). Als er geen kwalificatie is opgegeven, is `+` (Pass) de standaard. + ### Pass Accepteer de e-mail. De afzender is geautoriseerd. \- ### Fail Weiger de e-mail. De afzender is niet geautoriseerd. \~ ### Soft Fail Accepteren maar als verdacht markeren. Gebruik tijdens het testen. ? ### Neutral Geen uitspraak. Behandel alsof er geen SPF-beleid is. Geavanceerde opties ## Modifiers ### redirect= Stuurt de SPF-verwerking door naar het SPF-record van een ander domein. Vervangt het beleid van het huidige domein volledig. `v=spf1 redirect=_spf.example.com` ### exp= Levert een aangepast toelichtingsbericht wanneer een SPF-controle mislukt. Handig voor diagnose. `v=spf1 ... -all exp=explain._spf.example.com` Praktijkvoorbeelden ## Veelvoorkomende voorbeelden van SPF-records ### Basis - één IP `v=spf1 ip4:192.0.2.1 -all` ### Google Workspace + uw server `v=spf1 ip4:192.0.2.1 include:_spf.google.com -all` ### Google + Microsoft 365 `v=spf1 include:_spf.google.com include:spf.protection.outlook.com -all` ### A- + MX-records met soft fail `v=spf1 a mx include:_spf.google.com ~all` Aanbevolen werkwijzen ## Best practices - Gebruik nooit `+all` \- het autoriseert elke server op het internet - Houd het aantal DNS-lookups onder de 10 - gebruik zo nodig SPF flattening - Bekijk en werk uw SPF-record regelmatig bij wanneer u van e-mailprovider wisselt - Test uw record na elke wijziging met een SPF checker-tool - Vermijd het verouderde `ptr`\-mechanisme - Geef de voorkeur aan `-all` (hard fail) boven `~all` zodra u alle verzendbronnen hebt geverifieerd ## Beheer SPF-records niet handmatig AutoSPF flattent en optimaliseert het formaat van uw SPF-record automatisch.

I appreciate that it keeps a log of changes made, which prevents many mistakes. A client's SPF record would have way too many lookups, but AutoSPF makes that problem go away. The length of the SPF record is typically not the issue; it's the amount of lookups in the record that are. AutoSPF "flattens" the record, automatically expanding the defined lookups to IP addresses or ranges. And it auto-updates the record when the un-flattened lookups change. PJ Peter J. President · Small-Business (50 or fewer emp.) ### "Helped us go beyond capacity" > AutoSPF did exactly as described, it helped us get past our 10 lookup limit. Afterwards, we hit another limit regarding overall capacity and when contacted, they quickly provided us with a new solution to eliminate capacity issues entirely going forward, so now we can add as many SPF records as needed. They also provided us with a personalized support video explaining their new method in its entirety using our instance as the example. VU Verified User Financial Services · Mid-Market (51-1000 emp.)
