问题 I have a small tcp server that is used, among other things, to send mails through a SMTP server. The problem is, it works correctly when I run it on my development machine (a remote connection to the smtp server), however when I run the application on the same machine as the SMTP server (Windows Server 2008 R2) I get the following exception: System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: net_io

Sometime it happens that even if I receive an SMTP code 250 from the external mail server, the email diasappears and never get delivered or it is delivered after a very long time. Point is: am i right assuming that until i receive the SMTP code 250 of successful delivery from the external server, it is not a problem of my mail server? 回答1: Even you get

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 一般每个提供电子邮件服务的网站都有自己的SMTP和POP服务器地址，在你登录你的电子邮件网站时仔细找找肯定能发现它们，如果找不到还可以查看一下网站的“帮助”。如果你想详细的了解一下这其中的知识，就请看看下面的解释吧： POP（Post Office Protocol）邮局通讯协定 POP是互联网上的一种通讯协定，主要功能是用在传送电子邮件，当我们寄信给另外一个人时，对方当时多半不会在线上，所以邮件服务器必须为收信者保存这封信，直到收信者来检查这封信件。当收信人收信的时候，必须通过POP通讯协定，才能取得邮件。 与POP同时出现的还有SMTP，它也是用来传送网络上的电子邮件，不同的是POP是负责邮件程序和邮件服务器收信的通讯协定，SMTP则是负责邮件服务器与邮件服务器之间的寄信的通讯协定。 SMTP(Simple Mail Transfer Protocol)简易邮件传输通讯协议 SMTP是互联网上的一种通讯协议，主要功能是用在传送电子邮件，当我们通过电子邮件程序，寄E-mil给另外一个人时，必须通过SMTP通讯协议，将邮件送到对方的邮件服务器上，等到对方上网的时候，就可以收到你所寄的信。 其实简单的说，POP服务器是用来收信的，而且每个E_mail地址一般只有一个。如果你要同时收取多个邮箱的信件

POP3、SMTP和IMAP协议

由 无人久伴 提交于 2019-12-10 20:16:37
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1. POP3 POP3 是PostOffice Protocol 3的简称，即邮局协议的第3个版本,它规定怎样将个人计算机连接到Internet的邮件服务器和下载电子邮件的电子协议。它是因特网电子邮件的第一个离线协议标准,POP3允许用户从服务器上把邮件存储到本地主机（即自己的计算机）上,同时删除保存在邮件服务器上的邮件，而POP3服务器则是遵循 POP3协议的接收邮件服务器，用来接收电子邮件的。 2. SMTP SMTP 的全称是“Simple Mail Transfer Protocol”，即简单邮件传输协议。它是一组用于从源地址到目的地址传输邮件的规范，通过它来控制邮件的中转方式。SMTP 协议属于TCP/IP 协议簇，它帮助每台计算机在发送或中转信件时找到下一个目的地。SMTP 服务器就是遵循 SMTP 协议的发送邮件服务器。SMTP 认证，简单地说就是要求必须在提供了账户名和密码之后才可以登录 SMTP 服务器，这就使得那些垃圾邮件的散播者无可乘之机。 增加 SMTP 认证的目的是为了使用户避免受到垃圾邮件的侵扰。 3. IMAP IMAP 全称是Internet Mail Access Protocol，即交互式邮件存取协议，它是跟POP3类似邮件访问标准协议之一。不同的是，开启了IMAP后

问题 I'm a noob I know. So I want to build a web app that allows the user to enter text. Then have the web server send an email based on the text with a message from another file.

I just don't know where to start. 回答1: There is plenty of good guides online. The django documentation will take you step by step
