Hi All,

My name is Wisnu. I am currently evaluating TElSMTPClient before deciding to purchase.

I have configured my email account using Outlook, and trying to send a simple email from Delphi.

The configuration is below:
Port : 465
Encryption : SSL

In my code, beside address, port, username, and password I set:

smtp.UseSSL := True;

try
smtp.Open; //Error here
smtp.Login(smtp.Address);
Sleep(1000);
smtp.Close;
except
on E: Exception do
mmLog.Lines.Add('Error : ' + E.Message);
end;

The error:
Certificate validation handler is not assigned. Please handle the OnCertificateValidate event and implement proper certificate validation code there.

I don't know how to handle the event. Any source I can read?

Thank you for your interest in our products.

There are plenty of samples available in {SecureBlackbox}\Samples directory. All of HTTPS, SSL- and Mail-related samples include certificate validation in place. You can copy the code from there.


Sincerely yours
Eugene Mayevski

Hi Eugene,

Is there any explanation somewhere for the code in the sample?
I have successfully sent a test email to my SSL SMTP account.
I just want to know why the code is like that and other option as well.

The code was designed to be pretty much self-explaining, we are sorry if it's not. Is there any particular topics or code pieces you are interested in?

Actually, there are extensive how-to articles in the help file, which is installed on your disk and also is available online on the site.


Sincerely yours
