這篇文章分享一下自己把項(xiàng)目部署在阿里云ECS上之后，登錄郵件提醒時(shí)的郵件發(fā)送失敗問(wèn)題，無(wú)法連接發(fā)送郵箱的服務(wù)器。
博主使用的springboot提供的發(fā)送郵件服務(wù)，如下所示，為了實(shí)現(xiàn)異步的效果，新開(kāi)了一個(gè)線程來(lái)發(fā)送郵件。

... 8 more原因是：Couldn't connect to host, port: smtp.163.com, 25
但是通過(guò)終端連接smtp.163.com是成功的
ping smtp.163.com
但是嘗試訪問(wèn)25端口，卻無(wú)響應(yīng)
telnet smtp.163.com 25
于是在網(wǎng)上查找了一些解決方案，最后采用了通過(guò)ssl連接的方式，在原來(lái)的郵件設(shè)置中加入以下設(shè)置文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-729223.html
spring:
mail:
port: 25
host: smtp.163.com
default-encoding: UTF-8
username: xxxxx@163.com

# 以下是新增的設(shè)置

smtp:
auth: true
ssl:
trust: smtp.163.com
starttls:

socketFactory:

class: javax.net.ssl.SSLSocketFactory最后重啟服務(wù)，登陸的時(shí)候成功發(fā)出了郵件。文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-729223.html
到了這里，關(guān)于阿里云ECS服務(wù)器無(wú)法發(fā)送郵件問(wèn)題解決方案的文章就介紹完了。如果您還想了解更多內(nèi)容，請(qǐng)?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
