DNS
Prevent email scammers from impersonating you
A tip from @Jerry@hear-me.social.
If you own a domain and do not use it for email, you should set these two DNS records to ensure no one spoofs it.
| Type | Name | Value |
|---|---|---|
| TXT | @ | v=spf1 -all |
| TXT | _dmarc | v=DMARC1; p=reject; |
The first says there is not a single SMTP server on earth authorized to send email on behalf of your domain.
The second says that any email that says otherwise should be trashed.
