jira发送邮件的报错
1.安装完jira后，配置发送邮件出错具体报错如下：
An error has occurred with sending the test email:
com.atlassian.mail.MailException: javax.mail.MessagingException: Exception reading response;
nested exception is:
java.net.SocketTimeoutException: Read timed out

2.排查方法
（1）网上搜索的解决办法中大部分都没有用，好多都是使用网易163邮箱做的配置，而我使用的邮箱是腾讯企业邮箱配置，测试一直发送不了，下面是第一个报错信息
AuthenticationFailedException: 535 Error: authentication failed
这个错误主要是我太粗心，没有配置发送的邮件密码，后面添加密码后这个错误解决。
（2）第二个报错信息
不幸的是, 没有连接是可能的。审查以下错误并纠正:
- SocketTimeoutException: Read timed out
这里主要是端口问题，为465，测试报错，截图如下：
在这里修改端口成功解决，端口号可以是25，也可以是587，就是465会报错。
