asp.net - 从 asp.net 发送电子邮件时邮箱不可用消息

Question

我正在尝试从asp.net 登录页面发送注册电子邮件。但控制台显示此错误..

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Mailbox unavailable. The server response was: Delivery is not allowed to this address. 

什么可能导致此错误、代码或stmp 服务器配置错误。我在不是我自己的商业服务器上托管。

Answer 1

试试 yourClientName.DeliveryMethod = SmtpDeliveryMethod.Network;

例如：

SmtpClient client;
client = new SmtpClient("smtp.myserver.com", 25);

if (!string.IsNullOrEmpty(""))
{
     System.Net.NetworkCredential credential = new NetworkCredential("", "");
     client.Credentials = credential;
}
client.UseDefaultCredentials = true;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
