I'm using SMTPClient for sending emails to a SMTP server. But with Send method I can specify any false sender name or email. How can I prevent this?
答
确定邮件服务器作为发件人的电子邮件地址是您的工作，这只是政策问题.
It's the job of your mail server to decide on what it accepts as a sender email address - that's just a matter of policy.
邮件客户端没有真实的"电子邮件地址，因此客户端无法执行任何操作.
There is no 'true' email address for a mail client, so nothing that can be enforced at the client.
