I agree with the author of this blog, but he doesn't address the problem where you want to scrap all the email addresses in a text file. For this situation, I don't see what to use except regexp.
Yeah, but it you want to get all the emails in a text like "Please contact me at myfakemail@gmail.com. I already sent an email to contact@mycompany.com, but no one replied...", then you would have to use regexp.
