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.

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.

Are the registered mail servers allowed to send e-mails?

In the SPF entry the mechanism 'mx' has not been set
