Overview

Validate fields to look like emails

Is not an exhaustive check but prevents emails that can cause Postfix to crash. Specifically emails with special characters in the local part.

Does not consider a blank string as invalid.

Examples

validates :email, email_format: true                 # optional
validates :email, email_format: true, presence: true # required

Constant Summary collapse
