SSL check results of dollaracademy.org.uk

NEW You can also bulk check multiple servers.

Discover if the mail servers for dollaracademy.org.uk can be reached through a secure connection.

To establish a secure connection a mail server has to offer STARTTLS (SSL), a trustworthy SSL certificate, support for the Diffie-Hellman-Algorithm to guarantee Perfect Forward Secrecy and must not be vulnerable against the Heartbleed attack. Futhermore we recommend using end-to-end encryption with GnuPG.
