Azkaban邮件设置，修复Connecting to SMTP server failed

Azkaban邮件设置

解决 [Azkaban] Connecting to SMTP server failed，javax.mail.MessagingException: Exception reading response; java.net.SocketTimeoutException: Read timed out

本实例版本：azkaban-3.90.0

一、邮件配置

vim azkaban-web-server/conf/azkaban.properties

mail.sender=******@qq.com
mail.host=smtp.exmail.qq.com
mail.user=******@qq.com
mail.password=***********
mail.port=465

可是当你配置这些之后，发送邮件还是会报错，报错如下：
