在c#中通过gmail发送邮件时更改发件人地址

发布于 2024-09-26 11:17:54 字数 985 浏览 7 评论 0原文

我已使用以下代码使用 Gmail 帐户从我的 Web 应用程序发送邮件。我的问题是，我可以将发件人地址更改为原始发件人（gmail）地址以外的其他地址吗？我的代码如下：

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
System.Net.NetworkCredential cred = new System.Net.NetworkCredential("[email protected]", "*******");

无论我做什么都是无用的，因为我总是收到来自 [ 的邮件电子邮件受保护]。可以改变吗？

我已经改为 mail.From = new System.Net.Mail.MailAddress("[电子邮件受保护]"); 但我收到了发件人地址为 [电子邮件受保护]，而不是来自新的“发件人”地址。我认为 gmail smtp 会用原始凭据覆盖发件人地址。

I have used the following code to send mail from my web application using a gmail account. My question is, can i change the sender address to another address other than original sender(gmail) address?
My code is as follows:

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
System.Net.NetworkCredential cred = new System.Net.NetworkCredential("[email protected]", "*******");

Whatever i do is useless as i always receive mail from [email protected]. Is it possible to change it?

I have changed to
mail.From = new System.Net.Mail.MailAddress("[email protected]"); but i received the mail with the from address [email protected] and not from the new "From" address. I think gmail smtp overwrites the from address with the original credential.

解决方法是这样的：

使用上面的代码在Gmail中设置mail.From = new MailAddress(address, display name)
，进入邮件设置>>>帐户和导入。
在“邮件发送方式”中添加您将用作发件人的电子邮件帐户。（勾选别名）

这对我有用

Gmail 不允许您将 FROM 更改为与您的 Gmail 帐户不同的内容。

无论你使用什么，他们都会在转发之前重写它。这可以防止垃圾邮件/欺骗。

是的，只需使用 From 属性MailMessage

例如。

mail.From = "[email protected]";

编辑：另外，请参阅这篇文章，了解有关如何在 C# 中通过 gmail 发送电子邮件的更多详细信息

通过 Gmail 在 .NET 中发送电子邮件

编辑： 虽然这通常适用于邮件，但似乎不适用于 Gmail，因为 google 在发送之前会覆盖它（参见@Dave Wanta的回答）

Yes just use the From property of the MailMessage

eg.

mail.From = "[email protected]";

EDIT: Also, see this post for more detailed info on how to emails via gmail in C#

Sending email in .NET through Gmail

EDIT: Although this works for mail in general, it appears this won't work for gmail as google overwrite it before its sent (see @Dave wanta's answer)

如果您的发件人数量有限，您可以按照@philip 的建议进行操作。例如，您可能有 [电子邮件受保护] 、 [电子邮件受保护] 和 [电子邮件受保护] 甚至 [电子邮件受保护]。只要他们是实际 gmail.com 网站上批准的发件人，您就可以通过他们发送邮件。

Gmail.com：从其他地址发送邮件

如果您希望从任意用户处发送邮件（例如用户输入电子邮件的网站上的客户服务表格，并且您不希望他们直接向您发送电子邮件），那么您能做的最好的事情是：

        msg.ReplyToList.Add(new System.Net.Mail.MailAddress(email, friendlyName));

如果您'在受控环境中，这效果很好，但请注意，我看到一些电子邮件客户端即使指定了回复（我不知道是哪一个）也会发送到发件人地址。

If you have a limited number of senders you can do as @philip suggested. For instance you may have [email protected], [email protected] and [email protected] or even [email protected]. As long as they are approved senders on the actual gmail.com website you can send from them.

Gmail.com : Sending mail from a different address

If you are expecting to send from an arbitrary user (such as a customer service form on a website where the user enters their email and you don't want them emailing you directly) about the best you can do is this :

        msg.ReplyToList.Add(new System.Net.Mail.MailAddress(email, friendlyName));

If you're in a controlled environment this works great, but please note that I've seen some email clients send to the from address even when reply-to is specified (I don't know which).
