已尝试的解决办法：

另外找服务器部署了本地的，相同的配置功能，邮件能发出。不同地在于：本地测试的是在public下，云虚拟机，把文件从public里移出来了。

已处理，处理方案：
好像是因为阿里虚拟主机禁用了相关的php函数，需要使用fsockopen来完成smtp邮件发送。
修改vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php第272行：
$this->stream = stream_socket_client($host.‘:’.$this->params[‘port’], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, $streamContext);
改为：
$this->stream = @fsockopen($host,$this->params[‘port’],$errno,$errstr,$timeout);
相应的，虚拟主机需要在高级环境设置，PHP.INI设置中
PHP函数fsockopen设置:
改为启动。
