×Hello,
In order to prevent email spoofing, I would recommend the following things:
Add DKIM record - it is a process to validate sending domain names associated to email messages through cryptographic authentication.
Add a DMARC DNS record
Hope that this helps!

Thank you! I will forward the solution to my webmaster for implementation. Much appreciated!

Hi there @GaryConsultant,
No problem at all, hope that this helps!
And indeed as @twinedev mentioned it would not stop people from trying to spoof your email, but it should help the situation as the receiving email server would ‘know’ if the IP address which the email is coming from is authorized to send emails on your behalf or not and possibly discard the spoofed emails so that the recipients do not get them.

For clarification, the records do NOT prevent spoofing from happening, they help the receiver know what to do with them, reject, mark as spam, or nothing at all, depending if they are configured to do. The spammer can still fire off e-mails with incorrect “FROM” email addresses night and day.
