Check an email address
ROSVIX checks public DNS and mail-security records to help you understand basic email-domain risk.
Understand an Email Domain's Trust Indicators
Email addresses can look legitimate even when the underlying domain has weak or incomplete mail configuration. ROSVIX checks public technical information that can help you evaluate an email address more carefully.
MX records
MX records identify the mail servers configured to receive email for a domain. Their presence indicates that the domain has a mail delivery configuration.
SPF
SPF allows a domain to publish information about which mail systems are authorized to send email on its behalf. It is one component of email authentication.
DMARC
DMARC provides domain owners with a policy for handling messages that do not pass applicable email authentication checks and can help reduce certain forms of domain impersonation.
What the result cannot prove
Valid mail records do not prove that a particular sender or message is trustworthy. Legitimate domains can be compromised and attackers can register domains with technically valid email configurations.
Email Security Checker
Check an email address and its domain for common email security, authentication and trust indicators.
Verify before you trust.
An email address can look legitimate while using a poorly configured or disposable domain. ROSVIX checks common technical indicators to help you make a safer decision.
How to interpret email authentication signals
Email safety checks help explain whether a domain publishes records that support legitimate mail delivery and reduce some forms of email impersonation.
What the records mean
MX, SPF and DMARC records describe how a domain receives mail and how receiving systems may evaluate messages claiming to come from that domain.
How to use the result
Use technical records with the full message context. Check sender and reply-to addresses, inspect unexpected links and independently verify high-risk requests.
Important limitation
Email authentication does not make every message safe. A compromised legitimate account or a convincing social-engineering message can still be dangerous.
Example: an email that looks genuine at first glance
A message may use a familiar logo and convincing signature but still ask you to open a link urgently. Compare the sender domain, reply-to address, authentication indicators and destination URL before acting. When uncertain, contact the organisation through a known address.
