System.Net.Mail创建无效的电子邮件和eml文件？在主机名中插入额外的点

如果点出现在MIME编码行的开头(例如test.com有时显示为test..com),.NET的SmtpClient似乎正在创建主机名中带有额外点的电子邮件.示例代码:

[TestMethod]
public void TestEmailIssue()
{
    var mail = new System.Net.Mail.MailMessage();
    var smtpClient = new System.Net.Mail.SmtpClient();

    mail.To.Add("Test@test.com");
    mail.Subject = "Test";
    mail.From = new System.Net.Mail.MailAddress("test@test.com");
    mail.Body = "Hello this is  a short test of the issue:"
             +" <a href='https://test.com/'>https://test.com/</a>: ";

    smtpClient.PickupDirectoryLocation = "C:\\temp\\";
    smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.SpecifiedPickupDirectory;
    smtpClient.Send(mail);
}

这会创建一个如下所示的.eml文件:

X-Sender:test@test.com

X-Receiver:Test@test.com

MIME版本:1.0

来自:test@test.com

致:Test@test.com

日期:2011年7月6日15:55:28 -0400

主题:测试

内容类型:text/plain; 字符集= US-ASCII

Content-Transfer-Encoding:quoted-printable
