Bash script to check if a domain or list of domains can be spoofed based in DMARC records
File with domains:
sh SpoofThatMail.sh -f domains.txt
One single domain:
sh SpoofThatMail.sh -d domain
The script may not work if sp param is before p param (currently working on this)
Test manually using nslookup -type=txt _dmarc.domain.com
