Using ICS to send emails via Gmail SMTP

Other Questions Gmail
1

I’m trying to figure out how to use the Internet Component Suite (ICS) to send emails through a Gmail SMTP account. Has anyone done this before? I’m not sure about the exact steps or settings I need to configure.

Some specific questions I have:

  • Do I need to set up any special authentication?
  • Are there any port numbers or security settings I should be aware of?
  • Is there a simple code example showing how to connect and send a basic email?

I’ve looked at the ICS documentation but couldn’t find clear instructions for Gmail specifically. Any help or pointers would be really appreciated! I’m working on a project where this functionality is crucial.

I’ve actually tackled this issue recently in one of my projects. You’re on the right track with using ICS for Gmail SMTP. Here’s what worked for me:

First, you’ll need to enable 2-step verification on your Google account and create an app password specifically for your application. This bypasses the need for complex OAuth2 setup.

For the SMTP settings, use smtp.gmail.com as the server and port 465 for SSL or 587 for TLS. In your ICS configuration, make sure to set UseTLS to true.

A basic code snippet might look something like this:

SmtpClient.Host := ‘smtp.gmail.com’;
SmtpClient.Port := 587;
SmtpClient.Username := ‘[email protected]’;
SmtpClient.Password := ‘your-app-password’;
SmtpClient.UseTLS := true;

Remember to handle exceptions properly, as network issues can occur. Also, test thoroughly with different email clients to ensure proper delivery and formatting.

I’ve had success integrating ICS with Gmail SMTP in several projects. My experience shows that OAuth2 authentication is essential, as traditional password authentication no longer works reliably with Gmail. Use smtp.gmail.com with port 587 and enforce TLS encryption. In practice, configure your TSmtpCli component with the appropriate host, port, and username values, then obtain and set an OAuth2 access token as the password. Additionally, ensure your Google account permits access from less secure apps if needed, to avoid connection issues.
