Ruby Email validation with regex

Question

I have a large list of emails I am running through. A lot of the emails have typos. I am trying to build a string that will check valid emails.

this is what I have

Answer 1

This one is more short and safe:

/\A[^@\s]+@[^@\s]+\z/

The regular is used in Devise gem. But it has some vulnerabilities for these values:

  ".....@a....",
  "david.gilbertson@SOME+THING-ODD!!.com",
  "a.b@example,com",
  "a.b@example,co.de"

I prefer to use regexp from the ruby library URI::MailTo::EMAIL_REGEXP

There is a gem for email validations
