System.Net.Mail.MailMessage发邮件

Question

System.Net.Mail.MailMessage发邮件在本地测试成功,上传到服务器也可以,但应用程序一发布之后再上传,就发送失败,找不到原因,也不好断点测试

Answer 1

不是防火的问题,IIS里SMTP似乎一直没装过,我本机也没装过,

Answer 2

代码如下:
public bool Send()
        {            System.Net.Mail.MailMessage myEmail = new System.Net.Mail.MailMessage();
            Encoding eEncod = Encoding.GetEncoding("utf-8");
            myEmail.From = new System.Net.Mail.MailAddress(this.From, this.From, eEncod);
            myEmail.To.Add(this._recipient);
            myEmail.Subject = this.Subject;
            myEmail.Body = this.Body;
            myEmail.Priority = System.Net.Mail.MailPriority.Normal;
            myEmail.IsBodyHtml = this.Html; //邮件形式，.Text、.Html 
            System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
            smtp.Host = this.MailDomain;
            smtp.Port = this.MailDomainPort;
            smtp.Credentials = new System.Net.NetworkCredential(this.MailServerUserName, this.MailServerPassWord);
            
            //当不是25端口(gmail:587)
            if (this.MailDomainPort != 25)
            {
                smtp.EnableSsl = true;
            }
            //System.Web.Mail.SmtpMail.SmtpServer = this.MailDomain;            try
            {
                smtp.Send(myEmail);
            }
            catch (System.Net.Mail.SmtpException e)
            {
                string result = e.Message;
                return false;
            }            return true;
        }
    }
