SAV mail integration doesn't work with STARTLS in prestashop version 1.7.8.0.

[Yves Merlevède]

In is version 1.7.7.5 "SAV mail integration" function works with mail server configured with STARTTLS certificat. In is 1.7.8.0 version, it doesn't work. The mail server return the error below :

 TLS handshaking: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

/tls option seems not considered.

SSH certificats are unsafes.

Someone found a solution to resolve this error ?

Thanks for help.

Best regards !

Kindly contact the host provider about the same.

Hello,

Oracle Cloud Infrastructure provides the instances on which we install our servers and software ourselves.

"SSL routines:SSL23_GET_CLIENT_HELLO:unsupported protocol" means that the client tried to connect using SSLv2 while we explicitly forbid it. Our mail server does not allow the use of SSH for obvious security reasons. This security policy cannot change. That is why we do not understand that STARTTLS no longer works with the new version of prestashop. The configuration has not changed on our mail server between version 1.7.7.5 and 1.7.8.1 of prestashop. We do not understand this "regression".
