SMTP SSL for Sending Email

Download Chilkat Email ActiveX

Delphi example source code for connecting to an SMTP server using SSL and sending email. All communications, including authentication, occur over a secure connection.

// Sending email over an SMTP SSL connection is achieved
// by setting two properties:
// 1) The SmtpSsl property = 1 to indicate that an SSL connection should be created.
// 2) Set the SmtpPort property = 465, which is the typical port used by SMTP servers for SSL.
//
procedure TForm1.Button7Click(Sender: TObject);
var
  email: IChilkatEmail2;
  ok: Integer;

begin
  // A ChilkatMailMan2 ActiveX component was dropped onto the Delphi
  // form, and this became the Form's member variable "ChilkatMailMan21".

  ChilkatMailMan21.UnlockComponent('Anything for 30-day trial');
  ChilkatMailMan21.SmtpHost := 'smtp.comcast.net';

  // If our SMTP server requires authentication, set the username/password.
  ChilkatMailMan21.SmtpUsername := 'myUsername';
  ChilkatMailMan21.SmtpPassword := 'myPassword';

  // Tell the mailman to use SSL
  ChilkatMailMan21.SmtpSsl := 1;
  ChilkatMailMan21.SmtpPort := 465;

  email := ChilkatMailMan21.NewEmail();
  email.Subject := 'Email sent from a Delphi program!';
  email.From := 'Chilkat Support <support@chilkatsoft.com>';
  email.AddTo('Chilkat Admin','admin@chilkatsoft.com');
  email.Body := 'This email was mailed from a Delphi program...';

  // Connect to the SMTP server and send the email.
  ok := ChilkatMailMan21.SendEmail(email);
  if (ok = 0) then
        ChilkatMailMan21.SaveLastError('errorLog.xml');

end;
