+## [2.4.0] - 2021.04.28
+
+### Added
+
+- Implemented `MxBlacklist` validation. This layer provides checking mail servers with predefined blacklisted IP addresses list and can be used as a part of DEA ([disposable email address](https://en.wikipedia.org/wiki/Disposable_email_address)) validations.
+
+```ruby
+Truemail.configure do |config|
+  # Optional parameter. With this option Truemail will filter out unwanted mx servers via
+  # predefined list of ip addresses. It can be used as a part of DEA (disposable email
+  # address) validations. It is equal to empty array by default.
+  config.blacklisted_mx_ip_addresses = ['1.1.1.1', '2.2.2.2']
+end
+
+```
