try on your machine

The command "spfquery" is used to query the Sender Policy Framework (SPF) records for a given IP address and sender address. The command you provided is:

spfquery -ip ${8-8-8-8} -sender ${sender@example-com}

"-ip ${8-8-8-8}": This part specifies the IP address you want to check against the SPF records. In this case, ${8-8-8-8} is not a valid IP address format. It seems like there might be a mistake or placeholder in the command, as ${...} typically represents a variable in shell scripting. A correct IP address should look like "x.x.x.x" (e.g., 192.168.0.1).
"-sender ${sender@example-com}": This part specifies the email address of the sender you want to verify against the SPF records. Again, ${sender@example-com} is not a valid email address format. Generally, a valid email address should follow the format "username@example.com" (e.g., john@example.com).

Without further details or corrections, it is not possible to provide a more specific explanation of the command or its expected outcome.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
