Can firewell protection can enable sending mail from nodemailer

I think there may be a bit of confusion here!

Firewall protection and NodeMailer are two completely different things.

Firewall protection is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It's designed to prevent unauthorized access to or from a private network.

NodeMailer, on the other hand, is a popular Node.js package used to send emails programmatically. It allows you to send emails using various transport mechanisms, such as SMTP, Sendgrid, Mailgun, and more.

To send emails using NodeMailer, you need to configure it to connect to an email server (e.g., Gmail, Sendgrid, etc.) and authenticate with your email account credentials. This is a separate process from firewall protection.

In other words, firewall protection is not directly related to sending emails using NodeMailer. You can still send emails using NodeMailer even if you have a firewall protection system in place, as long as your email server and NodeMailer configuration are properly set up.

If you're experiencing issues sending emails using NodeMailer, it's likely due to a configuration problem or a issue with your email server, rather than a firewall protection issue.
