Hi @samirnext!

Can you help me out? Would you be able to provide some example code or even create a throw-away repo or a GitHub Gist with a sample app containing the pertinent code that isn't working? Don't include anything sensitive like credentials for your SMTP account. The gist is, do you have a reproduction case for me that I can use and go off of?

Also, would you be able to tell me what SMTP provider you are trying to authenticate against? (e.g. Google, Amazon SES, etc.)

I'm just going to leave a little more information here for you to see if you covered your bases.

At my work all of the SmtpClient configuration is done in the web.config/app.config files. We don't actually hard-code anything in the code. If you have the correct authentication and SmtpClient configuration settings in your web.config/app.config file, then Postal should just work out of the box, especially with let's say Gmail and Sasl.

• https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/network/network-element-network-settings

So in the "network" element, you need to make sure:

• defaultCredentials = false
• enableSsl = true
• Set the host, username, and password properties.

If you haven't tried those things go ahead and play around with that and let me know if that fixes your issue or not. If I don't hear back from you by the end of February I'll consider the issue closed.

Hi,
when i use dotnet smtp (without postal ) it work by adding this lines :

            ServicePointManager.ServerCertificateValidationCallback = (object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) => true;
            SmtpConexiune.DeliveryMethod = SmtpDeliveryMethod.Network;
            mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
            SecurityProtocolType oldSecurityProtocol = ServicePointManager.SecurityProtocol;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
            SmtpConexiune.Send(mail);
            ServicePointManager.SecurityProtocol = oldSecurityProtocol;

how i can enable the tls security protocole in tha app.config ?

thanks

Hi there! It sounds like you need to configure SASL authentication for sending email in your C# MVC laser application using Postal. You might want to check your SMTP settings and credentials. Ensure they match your email provider's requirements. If you still face issues, consider providing more details for specific help. Good luck.
