不能用plus符号(SmtpClient.Send()方法从System.Net.Mail发送电子邮件)

Can the SmtpClient.Send() method from System.Net.Mail really not send to email addresses that have plus symbols in them? I am sending to a list of email addresses and they all get sent except the ones that contain a plus (+) symbol. Any ideas or workarounds?

可以从System.Net发送()方法。邮件真的不发送给有加号的电子邮件地址吗?我正在发送一个电子邮件地址列表，除了包含+(+)符号的邮件外，它们都将被发送。任何想法或解决方案?

I successfully send emails to recipients with a + char in the address using System.Net.Mail with .net 4.

我成功地使用System.Net将邮件发送给地址中带有+ char的收件人。邮件与。net 4。

In my case, the recipients are gmail addresses, where the + and any chars after it don't change the recipient. So [e-mail] sends an email that is received by the [e-mail] account. But that account can see that it was sent to something+somethingelse.

在我的例子中，收件人是gmail地址，在这里，+和任何字符都不会改变收件人。所以[e-mail]会发送一封邮件给[e-mail]账户。但是那个账户可以看出它被发送给了某物+某物。

I think this is actually a sendmail standard, not just google stuff. It comes in handy.

我认为这实际上是一个sendmail标准，而不仅仅是谷歌之类的东西。它方便。

EDIT: I found some sendmail documentation on "plussed accounts":

Sometimes it is convenient to merge configuration on a centralized mail machine, for example, to forward all root mail to a mail server. In this case it might be useful to be able to treat the root addresses as a class of addresses with subtle differences. You can do this using plussed users. For example, a client might include the alias:

有时，在集中的邮件机器上合并配置是很方便的，例如，将所有根邮件转发到邮件服务器。在这种情况下，可以将根地址作为具有细微差别的地址类处理。您可以使用plussed用户来实现这一点。例如，客户端可能包含别名:

root: root+client1@server

根:根+ client1@server

On the server, this will match an alias for "root+client1". If that is not found, the alias "root+*" will be tried, then "root".

在服务器上，这将匹配“root+client1”的别名。如果没有找到，将尝试别名“root+*”，然后尝试“root”。
