There are a few things you can do to avoid your email domain being spoofed:
- Use DMARC: DMARC is an email authentication standard that helps to prevent email spoofing. It stands for Domain-based Message Authentication, Reporting & Conformance.
- Configure SPF and DKIM: SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are email authentication methods that help to verify that an email is coming from the domain it claims to be coming from.
- Keep your email system up-to-date: Make sure that you are using the latest version of your email software and that all security patches have been applied.
- Educate your users: Make sure that your users are aware of email spoofing and how to spot it. Phishing emails often spoof well-known brands or companies, so educate your users on how to spot these fake emails.
