E-Mail handling

How should the checkHost() function of the e-mail server handle the e-mail? (syntax )

~all
SoftFail (non-compliant e-mails are accepted but marked)

Will be forwarded to another SPF record?

There is no reference to any other SPF record

Are the server addresses allowed to send e-mails?

In the SPF entry the mechanism 'a' has not been set.

Additionally authorized A-records?

In addition to the A-Records stored in the DNS, we could not find any other records authorized in the SPF-Record.

Additionally authorized MX records

We could not find any other records authorized in the SPF record besides the MX records stored in the DNS

Additionally authorized IPv6 addresses

No explicit IPv6 addresses in the SPF record have been authorised to send

How is the sender informed?

The exp mechanism acts as a return to the sender if the IP address was not authorized to send and notify them. None was found.

PTR (obsolete mechanism)

The ptr mechanism is deprecated, slow and insecure and should not be used

The ptr mechanism is deprecated, slow and insecure and should not be used

Authorize IP addresses with markers

When SPF is evaluated, macros can specifically authorize Ip addresses based on the request or connection of the user or client (RFC7208 )

Receiver address

Amount of reports

Unknown mechanisms

No unknown mechanisms were found in the SPF record.

What is the SPF lookup for?

With the SPF lookup you analyze the SPF record of a domain for errors, security risks and authorized IP addresses. Optionally, you can specify an IP address to check if it is authorized to send e-mail on behalf of the domain. The SPF lookup analyzes registered TXT records in real time. If you want to specify an SPF record manually, use the SPF Analyzer.

How secure are your domains and where are the dangers lurking?

Domain risks are often underestimated

A current study by BITKOM reports on the alarming increase in cyber attacks on German companies, the ICANN warns of attacks on the global domain name system and the Federal Office for Information Security (BSI) sees significant risk potential in dealing with domain name. Unfortunately, these risks come into play every day, although this damage could have been prevented.

What should companies know and what can they do?

Practical and with many examples, the over 20-page eBook deals with the basics of domain risk management, specifies legal obligations and deals with responsibilities and liability issues. Numerous domain risks (e.g. "Domain Hijacking") are clearly described and the risk assessment and possible consequences are discussed.

Checklist: What about my own domain risks?

The Risk Atlas supports domain managers to get a first impression of their own risk potential in the company. The checklist includes 53 questions on 14 risk areas and enables a quick introduction to the topic.
