Inspect DNS Record
First of all, Gosurp allow you to inpect DNS records.
gosurp inspect domain <yourdomain.com>
You can also look for specific DNS records using:
gosurp inspect (spf/dkim/dmarc) <yourdomain.com>
Email usurpation
First of all, to allow you working on building the good mail without sending it, you can use the following command to start a local SMTP server that will print the mail content in the console like a debugger.
gosurp smtp listen -vvv
# or
gosurp smtp listen --hostname localhost --port 2525 -vvv
Then, you can use the following command to send a mail using the local SMTP server.
gosurp smtp send -vvv --from attacker@fsociety.local --to victim@localhost --port 2525
You can find some complete recipes in the documentation.
