Email Validation

In this example, we are loading in a file where we want to check the validity of the email address contained within it. The results are written to Accepted and Rejected type output files. Clover offers three types of email validation

  • checks that the general email syntax (structure) is valid

  • check that the domain name used within the email address is valid

  • check that the email address itself exists within the domain name referenced by the email address

 

Related Points of Interest

The three email checks take very different amounts of time. The syntax check is very fast, but the other two are very slow as they need to perform lookups on the web and the responsiveness of the domains is beyond our control.
