Telnetworks MTA-STS Check
Check your domain names MTA-STS status and configuration
Mail Transfer Agent Strict Transport Security
MTA-STS is an internet security standard (RFC 8461) that forces email servers routing email to use encrypted connections in the data transmission process and blocks downgrade attacks.
It fixes gaps in regular STARTTLS by making encryption mandatory rather than optional which stops interception of data and middle-man attacks.
Our MTA-STS configuration checker tool enables testing of your domain names MTA-STS configuration.
Enter your domain name below without the (https://www) part.
For example: google.com or telnetworks.com.au or microsoft.com
Use the telnetworks.com.au (i.e. this website) domain name as an example configuration.
MTA-STS Record Builder
Use the Record Builder tab above to setup and configure your MTA-STS configuration for your domain name
Also see our SPF Record Check tool which enables you to check your SPF record.
If you require assistance building MTA-STS, our Network Operations Center is available 24/7/365. Alternatively, please contact us on the form below.
MTA-STS A vital Scope of Cyber Security
MTA-STS (Mail Transfer Agent Strict Transport Security) is a vital scope of cyber and email security. This standard enforces secure TLS encryption in data transmission whilst preventing downgrade attacks and stops man-in-the-middle attacks during server-to-server relaying.
Traditional outbound email relaying (SMTP) can drop down to unencrypted text. The MTA-STS standard makes encryption mandatory and enforces E-Mail relaying servers to communicate via encrypted connections only. Additionally, MTA-STS makes sure mail servers use trusted, valid security certificates.
The most vital aspect of MTA-STS is that it stops hackers from reading or changing emails while they move between servers.
Telnetworks Web Servers are fully capable of hosting MTA-STS configurations for all domain names.
