Отправка нашей электронной почты с использованием AWS SMTP работает нормально с кодом оболочки ниже power Но теперь asp. net Код 

[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12;
$EmailFrom = "tester@test.com"
$EmailTo = "test@itest.in"
$Subject = "Test email sent from Amazon SES"
$Body = "This message was sent from Amazon SES using Windows PowerShell."
$SMTPServer = "email-swestnorth.amazonaws.com"
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("testuser", "<password>");
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)
Remove-Variable -Name SMTPClient

Наш ASP. NET Код, который не работает нормально 

static SmtpClient mSmtpClient = null;
static NetworkCredential mNetworkCredential = null;
MailMessage message = null;

message = new MailMessage()
{
    Body = notification.Body,
    From = notification.From,
    IsBodyHtml = notification.IsBodyHTML,
    Subject = notification.Header
};
PrepareTo(notification.To, message);
PrepareCC(notification.CC, message);
PrepareBcc(notification.BCC, message);
PrepareAttachments(notification.Attachment, message);
System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls12;
mSmtpClient.Send(message);

ОШИБКА для этой операции с использованием ASP. NET SMTP-классов
