Ability to use fail fast behaviour for SMTP validation layer. When smtp_fail_fast = true it means that truemail ends smtp validation session after first attempt on the first mx server in any fail cases (network connection/timeout error, smtp validation error). This feature helps to reduce total time of SMTP validation session up to 1 second.

Truemail.configure do |config|
  config.smtp_fail_fast = true # by default it's equal to false
