阿里云封禁端口25，导致邮件无法发送-解决方案

问题描述

java开发中用到了email邮件发送功能，在本地测试中一切正常，邮件可以正常发送，但是在部署到服务器上之后，发现邮件无法发送，于是找到了报错的信息，如下：

解决方案

经过一番查找资料后发现，问题出在阿里云服务器把“25”号端口封禁了。网上查找资料后发现主要有两种解决方案（当然不止两种，哈哈）：

1、在阿里云中申请“25”端口解封，然而并没软用，阿里家大业大，没这兴趣帮你解封，申请几次都不通过，于是放弃。。。

2、采用ssl方式发送邮件，这时用到的端口为465，主动避开了默认的25端口，经过一番调试后，邮件正常发送。

我采用springboot进行开发，如果采用25端口发送邮件，配置如下：

spring:mail:host: password: testusername: test@properties:mail:smtp:auth: truestarttls:enable: truerequired: true

上面配置，在开发中是可以正常使用的，但是如果部署到阿里云环境，这种配置需要用到的25端口被毙了，尽然没有通知，上线就是妥妥的一个bug，默默的流下心酸的泪水。。。。

言归正传，采用ssl+465端口方式发送邮件，springboot配置如下：

spring:mail:host: port: 465password: testusername: test@properties:mail:smtp:auth: truessl:enable: truesocketFactory:port: 465class: .ssl.SSLSocketFactory

本地测试ok，阿里云测试ok。
