阿里云服务器发送邮件:Connection could not be established with host smtp.qq.com [Connection timed out #110]

一、总结

一句话总结:

端口号port 改成 465,加密方式 encryption 改用 ssl

二、Connection could not be established with host smtp.163.com

laravel阿里云屏蔽25,无法发送邮件的解决方案

本地测试邮件可以发送成功,但是部署在阿里云服务器上之后,并且在安全组中配置了25端口的出入后还是不行。

原因是:

阿里云服务器封禁了25

解决办法

  端口号port 改成 465

  加密方式 encryption 改用 ssl

也就是加入了SSL验证

阿里云服务器发送邮件:Connection could not be established with host smtp.qq.com [Connection timed out #110]

三、laravel中成功配置实例

阿里云服务器发送邮件:Connection could not be established with host smtp.qq.com [Connection timed out #110]

三、阿里云服务器25邮件端口问题

配置示例:

spring:
mail:
host: smtp.163.com
username: 1111111@163.com
password: aaaaaaaa
default-encoding: UTF-8
properties:
mail:
smtp:
auth: true
ssl:
trust: smtp.163.com
socketFactory:
class: 'javax.net.ssl.SSLSocketFactory'
port: 465
starttls:
enable: true
required: true

四、阿里云服务器邮件发送

https://www.cnblogs.com/eye-like/p/10103783.html

一个邮件发送的功能,本机调试无问题,但发布到阿里云服务器后邮件发送功能失败。

网上查了下大概是说阿里云把发送邮件的25端口禁用掉了

阿里云服务器发送邮件:Connection could not be established with host smtp.qq.com [Connection timed out #110]

那么解决方式一就是向阿里云申请开放25端口,但具体如何申请,并未深入操作。

解决方式二:使用邮件服务商的加密端口。

但是当使用465端口时,先后试验过smtp.mxhichina.com(阿里企业邮箱)、smtp.163.com(163邮箱)、smtp.qq.com(qq邮箱)三种发送方式,均失败!

再尝试考虑SSL加密SMTP通过587端口进行发件,发送成功。

以下为配置及源码

<?xml version="1.0" encoding="utf-8"?>
<xml>
<!--收件人邮箱地址-->
<ConsigneeAddress>pro@163.com</ConsigneeAddress>
<!--抄送邮箱地址,多个邮箱间用'|'分割-->

<!--发件人名称-->

<!--发件邮件服务器的Smtp设置-->

<!--发件人的邮件-->

EmailParameterSet

说明:

实例中使用的是qq邮箱,但邮箱的密匙非qq的密码,而是邮箱的独立密码,可以进入qq邮箱,然后在设置-》账户里面设置

并且要保证邮箱的POP3/SMTP服务开启,同样是进入qq邮箱,然后在设置-》账户里面设置

阿里云服务器发送邮件:Connection could not be established with host smtp.qq.com [Connection timed out #110]
