推荐答案

通常会出现"550访问被拒绝–无效的HELO名称" SMTP错误当配置为电子邮件发件人身份的一部分的SMTP域与发件人的电子邮件地址不匹配时.因此，基于此更改您的代码...

A "550 Access Denied – Invalid HELO name" SMTP error usually occurs when the SMTP Domain configured as part of an email sender’s identity does not match the senders email address. So based on that make changes in your code...

发送具有安全连接的电子邮件.使用此代码发送电子邮件.

公共布尔SendEmialWithSecure(字符串ToEmailId，字符串FromEmailId，字符串FromName，字符串SenderEmailId，
字符串SenderName，字符串Subject，字符串MailBody，字符串SMTPHost，Int32 SMTPPort，
字符串CredentialEmailId，字符串CredentialPassword)
{
System.Net.Mail.MailMessage ResetPassMail =新的System.Net.Mail.MailMessage();
SmtpClient SmtpServer =新的SmtpClient();
ResetPassMail.To.Add(新的MailAddress(ToEmailId));
ResetPassMail.From =新的MailAddress(FromEmailId，FromName);

ResetPassMail.Subject =主题；
ResetPassMail.IsBodyHtml = true;
ResetPassMail.Body = MailBody;
ResetPassMail.Priority = System.Net.Mail.MailPriority.High;

SmtpServer.Host = SMTPHost;
SmtpServer.Port = SMTPPort;
SmtpServer.Credentials =新的NetworkCredential(CredentialEmailId，CredentialPassword);
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
试试
{
SmtpServer.Send(ResetPassMail);
返回true;
}
捕获(SmtpException smtpExe)
{
抛出新的Exception("Message:" + smtpExe.Message +"Details:" + smtpExe.ToString());
}

}

send email with secure connection. use this code for sending email.

public bool SendEmialWithSecure(string ToEmailId, string FromEmailId, string FromName, string SenderEmailId,
string SenderName, string Subject, string MailBody, string SMTPHost, Int32 SMTPPort,
string CredentialEmailId, string CredentialPassword)
{
System.Net.Mail.MailMessage ResetPassMail = new System.Net.Mail.MailMessage();
SmtpClient SmtpServer = new SmtpClient();
ResetPassMail.To.Add(new MailAddress(ToEmailId));
ResetPassMail.From = new MailAddress(FromEmailId, FromName);
ResetPassMail.Sender = new MailAddress(SenderEmailId, SenderName);
ResetPassMail.Subject = Subject;
ResetPassMail.IsBodyHtml = true;
ResetPassMail.Body = MailBody;
ResetPassMail.Priority = System.Net.Mail.MailPriority.High;

SmtpServer.Host = SMTPHost;
SmtpServer.Port = SMTPPort;
SmtpServer.Credentials = new NetworkCredential(CredentialEmailId, CredentialPassword);
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
try
{
SmtpServer.Send(ResetPassMail);
return true;
}
catch (SmtpException smtpExe)
{
throw new Exception("Message :" + smtpExe.Message + " Details : " + smtpExe.ToString());
