请建议

解决方案

显然它看起来像是权限问题，在此之前您可能有权使用此特定IP和端口发送电子邮件，但现在它似乎已被撤销，否则您的代码看起来很好，如果没有与网络相关的
权限问题，它应该可以正常工作。

谢谢，

    MailMessage mail = new MailMessage();
            SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

            mail.From = new MailAddress("[e-mail]");
            mail.To.Add("[e-mail]");
            mail.Subject = "Contact Form";
            mail.Body = "Entity :\n" + entity + "\nTrading :" + trading + "\nCompany registration Number:" + company + "\nContact person :" + contact + "\nDesignation :" + designation + "\nTelephone Number :" + telephone + "\nMobile Number :" + mobile + "\nEmail Address :" + email + "\nEnquiry :" + area + "\nEnquiry from CEO :" + a;

            SmtpServer.Port = 587;
            SmtpServer.Credentials = new System.Net.NetworkCredential("kxxxxxxx", "Kxxxxxxxxx");
            SmtpServer.EnableSsl = true;

            SmtpServer.Send(mail);

It was working before , now is giving me the below error 

An attempt was made to access a socket in a way forbidden by its access permissions 74.125.206.109:587

please advice

解决方案

Apparently it looks like to be the permissions issue, before that you might had permissions to send email using this particular IP and port but now it seems to be revoked, otherwise your code looks fine and it should work if there are no network related permissions issue.
