PHP握手失败TLS1.0

我尝试通过fsockopen连接到465端口上的sendm.cert.legalmail.it,是意大利的名为PEC的SMTPS服务.

使用任何版本的PHP我都试过这个片段工作：

<?PHP
fsockopen('tls://sendm.cert.legalmail.it',465);

所有这一切都可以使用OpenSSL 1.0.2h,如果我升级到OpenSSL 1.0.2j这个代码片段失败并出现此错误：

PHP Warning:  fsockopen(): SSL operation Failed with code 1. OpenSSL Error messages:
    error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure in ~/Development/experimental/PHP-handshake/connect.PHP on line 3
    PHP Warning:  fsockopen(): Failed to enable crypto in ~/Development/experimental/PHP-handshake/connect.PHP on line 3
    PHP Warning:  fsockopen(): unable to connect to tls://sendm.cert.legalmail.it:465 (UnkNown error) in ~/Development/experimental/PHP-handshake/connect.PHP on line 3

所以使用OpenSSL 1.0.2j我尝试通过命令行连接：

openssl s_client -connect sendm.cert.legalmail.it:465

它完美地运作.

我尝试使用testssl在服务器上检查SSL,这是转储(剥离)：

SSLv2               not offered (OK)
SSLv3               not offered (OK)
TLS 1               offered
TLS 1.1             not offered
TLS 1.2             not offered
Version tolerance   downgraded to TLSv1.0 (OK)

只有TLS 1是可用的,我尝试用这个uri强制握手到TLS1：’tlsv1.0 :: //sendm.cert.legalmail.it’但结果是一样的.

我在Ubuntu 16.04上,使用PHP5.6和PHP7.1进行测试.

这个bug在哪里？在openssl？在PHP？在服务器握手？

更新,如果我总是使用./testssl.sh -E sendm.cert.legalmail.it:465与OpenSSL 1.0.2j返回时查看chiper：
