通过.net 2005的System.Net.Mail.SmtpClient发送邮件到Notes不知道为什么一直不成功，大侠救我！

[fgcsh]

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage("[e-mail]", "[e-mail]", "abc", "bcd");
mail.BodyEncoding = System.Text.Encoding.ASCII;
mail.SubjectEncoding = Encoding.ASCII;
mail.IsBodyHtml = false;
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("192.168.0.3");
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Timeout = 20000;
smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "123456");
smtp.Send(mail);

------------
提示错误：System.Net.Mail.SmtpException:Server does not support secure connections.

另外我用OutLook发送成功。

我用下面代码，是可以发送的
string dominoServerIP = "10.17.15.7";
string fromEmail = "[e-mail]"
string toEmail = "ca@10.17.15.7";
System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(dominoServerIP );
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential(fromEmail , "");
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(fromEmail , toEmail , "Test", "This is a test mail!");
message.BodyEncoding = System.Text.Encoding.UTF8;
message.IsBodyHtml = true;
client.Send(message);

你把[e-mail]和[e-mail]改成ca@192.168.0.3和cs@192.168.0.3试试看

他能用outlook发送成功,看来不是域名问题
莫非是smtp不允许匿名访问?

[fgcsh]

不允许的。

但这一句不是加了吗？
smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "123456");

[sense]

smtp.EnableSsl = false;

应和其它的SMTP一样的吧
