email - 使用例如 Outlook Web Access (OWA) 时如何发送电子邮件

Question

如今，也可以在网络上访问电子邮件。Web 协议是 Https 或只是计划 Http 。

但正如每个人都知道，电子邮件使用诸如 Pop3、Smtp 或 Imap 之类的协议。

那么在网络上是否还会使用例如 SMTP 来发送电子邮件？

如果是，它将如何工作。smtp 协议是否会以同样的方式嵌入到 http 协议中，例如 SOAP 嵌入到 http 中。

谢谢。

As you said, for sending mails the SMTP protocol is used. The server you are accessing via HTTP(S) when using for example OWA will handling this protocol for you.

Basically you as a client using OWA will tell the server (MS Exchange) to send a mail. But the communication between you two is using the HTTP(S) protocol. And as a result of your communication the Exchange Server will use the SMTP protocol as a client to issuing the sending of your email.
