ANSMTP SMTP COMPONENT SDK DOCUMENTATION

ComputerName Property

Domain name to send in HELO/EHLO command

Data Type: String

Remarks

In HELO/EHLO SMTP command, a domain name is required to identify your current computer. The default value is your current machine name. You can change this value by ComputerName property.

Some SMTP servers check this name strictly by DNS reverse lookup. To cross this check, you can assign "LocalIP" to this property, then IMail would choose a smart name automatically.

If you use FastSender object to send email, please refer to ComputerName property of FastSender.

Usage Example:

[Visual Basic]

Private Sub SendEmail()
  Dim oSmtp As AOSMTPLib.Mail
  Set oSmtp = New AOSMTPLib.Mail

  oSmtp.ServerAddr = "mail.adminsystem.net"
  oSmtp.FromAddr = "test@adminsystem.net"
  oSmtp.AddRecipient "Support Team", "support@adminsystem.net", 0
 
  oSmtp.ComputerName = "LocalIP"
  
  oSmtp.BodyText = "Hello, this is a test...."
  If oSmtp.SendMail() = 0 Then
    MsgBox "Message delivered!"
  Else
    MsgBox oSmtp.GetLastErrDescription()
  End If
End Sub

[C#]

private void SendEmail()
{
  AOSMTPLib.MailClass oSmtp = new AOSMTPLib.MailClass();
  oSmtp.ServerAddr = "mail.adminsystem.net";
  oSmtp.FromAddr = "test@adminsystem.net";
  oSmtp.AddRecipient( "Support Team", "support@adminsystem.net", 0 );

  oSmtp.ComputerName = "LocalIP";
  
  oSmtp.BodyText = "Hello, this is a test....";
  if( oSmtp.SendMail() == 0 )
    Console.WriteLine( "Message delivered!" );
  else
    Console.WriteLine( oSmtp.GetLastErrDescription());
}
