SPF include

Great care is needed to ensure that include: mechanisms do not place domains at risk for giving SPF Pass results to messages that result from cross user forgery. Unless technical mechanisms are in place at the specified otherdomain to prevent cross user forgery, include: mechanisms should give a Neutral rather than Pass result. This is done by adding ? in front of IP-Adresse des Senders durch den SPF-Record einer anderen Domäne legitimiert wird: include: eine zusätzliche SPF-Anfrage zur im Include-Statement angegebenen Domain die IP-Adresse des Senders enthält: exists: IP-Adresse des Senders anhand der Verbindung des Clients oder andere Kriterien nach (RFC7208 ) authorisiert wurd

Including domains in your SPF record A constraint when using domains in your SPF record is the limit of 10 DNS queries performed by a verifying server. Exceeding 10 DNS queries results in a failed SPF verification. All of the mechanisms and modifiers listed below result in a DNS query SPF implementations MUST limit the number of mechanisms and modifiers that do DNS lookups to at most 10 per SPF check, including any lookups caused by the use of the include mechanism or the redirect modifier. If this number is exceeded during a check, a PermError MUST be returned Trust relationships — The include: mechanism is meant to cross administrative boundaries.

Der SPF-Record wird als DNS-Record in der Domänenzone des zuständigen DNS (Namenservers) der Domain eingetragen, und zwar als TXT-Record. Der Eintrag enthält eine Liste der IP-Adressen, von denen Mails dieser Domain versendet werden dürfen. Hinzu kommen weitere Einträge, z. B. für die oben erwähnten Mail-Filter-Server, die eine Mail durchlaufen muss, bevor sie den Weg zum Empfänger findet. Solche Zwischenstationen werden oft mit de include: Fetch the entire SPF record for the domain, evaluate IP against it, and if a PASS is found then that PASS becomes the result of the whole SPF test. If no PASS is found then it's not a fail, but your original/top-level SPF test continues (probably to the -all/~all/?all phase) There's no restriction against including multiple names in a single entry; Hotmail, for instance, takes this to extremes. Note that multiple includes, or nested ones, need to stay under the limit of 10 total DNS lookups for the whole SPF check. It look like you can merge both together into one entry Zu externem SPF-Record delegieren (Include) Sollte der Mailversand auf Basis einer anderen Domain erfolgen, beispielsweise dass Sie über Server Ihres ISP E-Mails versenden und dieser einen SPF-record veröffentlicht hat, so geben Sie pro Zeile eine Domain an

This doesn't mean that your SPF record can only have 10 items. It means that processing the SPF should cause no more than 10 DNS lookups. For example, the following SPF record has only 2 terms but includes 254 IP Addresses and an include for a total of 265 addresses: v=spf1 ip4:123.123.123.2/24 include:sgizmo.com -all Der SPF-Record ist also eine Angabe, die in der DNS-Zone einer bestimmten Domain gemacht wird, die definiert, welche Server überhaupt E-Mails von dieser Domain einliefern können. Eingehende E-Mail-Server können diese Angabe prüfen, müssen es aber nicht. Durch die Prüfung wird aber recht effektiv Spam verhindert, da Spam sehr häufig in falschem Namen über fremde E-Mail-Server verwendet.

  1. The include mechanism allows you to designate other domains that are independent from your primary one. For example, alpha.net might send mail using beta.net and gamma.net. v=spf1 include:beta.net include:gamma.net -all. Also, you can point to your primary domain by adding include:alpha.net in SPF records of your secondary domains
  2. The include mechanism makes it possible to allow 3rd-party IP addresses defined in another SPF record to be included in the master SPF record.

For example, a user domain has an SPF record and has already included the Elastic Email SPF entry but is still not verifying correctly on the dashboard. The reason for it would be that there are two SPF records present on the domain: v=spf1 a mx include:_mypartnerdomain1.com include:_spf.elasticemail.com ~al Es gibt noch einige andere Anweisungen, z.b. kann man mit include ganze SPF Anweisungen von anderen Domains übernehmen.

If SPF record, resolved from include mechanism, contains another include mechanism then DNS lookups count increases by one, and so on. It is not so easy to count the number of lookups and identify the limit's exceed without the use of a special lookup tool. So a Google customer whose SPF includes the Google-recommended record will actually have a domain lookup count of four — one for the _spf.google.com lookup, and one for each of the three Google subdomains referenced by the first lookup. Now imagine you want to include the records provided by a number of other email service providers — each of which may have several DNS lookups themselves. v=spf1 include:spf.example.com include:spf.crsend.com ~all. Hardfail. Ein Hardfail definiert, dass alle anderen Versender abgewiesen werden. Standardmäßig ist der Hardfail deaktiviert und der Softfail aktiviert. Somit sind bestimmte Versender erlaubt, wodurch Ihre Newsletter bei Ihren Kunden zugestellt werden. Wenn Sie einen SPF-Eintrag mit Hardfail bevorzugen, nutzen Sie bitte den Eintrag. TXT Eintrag setzen. Wenn du die MX Records hinterlegst, dann setze bei deinem Domain-Anbieter auch einen sogenannten TXT Eintrag, um die Gefahr zu reduzieren, dass deine Nachrichten von scharf eingestellten Spamfiltern aussortiert werden.

SPF specification has fixed a limit on the number of DNS lookups to resolve an SPF record.The RFC Specification Document RFC7208 specifies that the number of mechanisms and modifiers that do DNS lookups should not exceed 10 per SPF check.Generally, the reckless use of the include or the redirect modifier in an SPF record can result in the DNS. This record above is too long and needs to be shortened; you will have to split this up into two or more records and include them in the main SPF record. Create the following SPF records on the domain name: spf1.sampledomain.com TXT v=spf1 a mx a:mail.domain.com a:mail.domain.ie a:server5.somedomain.com -all; spf2.sampledomain.com TX Avoid unnecessary include statements. An include statement is a mechanism in your SPF record that redirects the DNS lookup to another domain's SPF record to verify any of their authorized IPs. Each include statement, in the original SPF record and in any of the SPF records redirected to, is counted toward the limit of 10
