Topic: Validate Email via SMTP

I need to be able to check if an email exists. I've read about using RCPT TO smtp commands, but I'm lost on how to implement this using SMTP library of Ruby.

Many thanks!

Found a solution to this.

I use this: https://github.com/pash/email_veracity_checker which is based on this https://github.com/skillnet/validates_email_with_smtp
