Magic Links with nodemailer: How to send emails always to the same receiver independent of the user's email address?

[Coop4Free]

I use NextAuth together with Magic Links and Nodemailer for authentication on my website.

I created several users with different fictitious email addresses for testing.

During development, it would be bad if next-auth sends login emails to my users' email addresses, as they are just fictitious. Instead, I want next-auth to send all emails to my own email address so that I don't accidentally send test emails to other people's real email accounts.

I have already tried the following things:

const configuration: AuthOptions = {
  providers: [
    EmailProvider({
      server: {
        options: {

          // this is what I tried
          to: 'myaddress@gmail.com',
          envelope: {
            to: 'myaddress@gmail.com',
          },
          sendmail: true,
          args: [ 'to_addr', 'myaddress@gmail.com' ],

        },
        host: process.env.EMAIL_SERVER_HOST,
        port: parseInt(process.env.EMAIL_SERVER_PORT!),
        auth: {
          user: process.env.EMAIL_SERVER_USER,
          pass: process.env.EMAIL_SERVER_PASSWORD,
        },
      },
      from: process.env.EMAIL_FROM,
    }),
  ],
  // other configuration
}

But nothing seems to work. Does anyone have another idea?
