I am new to the SMTP related concepts. I am currently developing a nodejs email client using Nodemailer. In which, I am unable to receive the bounce back emails (NDRs). My queries below,
To achieve this should I configure DSN or envelope? I think I'm confusing myself with the dsn and envelope options.
How does nodemailer get the bounced email? Any separate configuration needed for this? Or any event listener?
Thanks in advance.
