生产，

*******************************************************************
 Using the default of SSL_verify_mode of SSL_VERIFY_NONE for client
 is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER
 together with SSL_ca_file|SSL_ca_path for verification.
 If you really don't want to verify the certificate and keep the
 connection open to Man-In-The-Middle attacks please set
 SSL_verify_mode explicitly to SSL_VERIFY_NONE in your application.

之后libnet并IO::Socket::SSL升级到1.954构造函数静默失败。

这是Net::SMTP::SSL->new选项Debug：

Net::SMTP::SSL>>> Net::SMTP::SSL(1.01)
Net::SMTP::SSL>>>   IO::Socket::SSL(1.954)
Net::SMTP::SSL>>>     IO::Socket::INET6(2.69)
Net::SMTP::SSL>>>       IO::Socket(1.34)
Net::SMTP::SSL>>>         IO::Handle(1.33)
Net::SMTP::SSL>>>           Exporter(5.67)
Net::SMTP::SSL>>>   Net::Cmd(2.30)

安装根证书SHA1 Fingerprint=D2:32:09:AD:23:D3:14:23:21:74:E4:0D:7F:9D:62:13:97:86:63:3A在哪里可以找到 OpenSSL它。

考虑从那个古老的模块切换到更现代的模块，例如Email::Sender::Transport::SMTP::TLS或Net::SMTPS，它们使 SSL 设置可配置。
