Validation of email which not contains whitelisted domain always will return `false`. It is equal `false` by default. |
 | `BLACKLISTED_MX_IP_ADDRESSES` | `127.0.1.1,127.0.1.2` | - | 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. Accepts one ore more values separated by commas.
 | `DNS` | `8.8.8.8,8.8.4.4:53` | - | This option will provide to use custom DNS gateway when Truemail interacts with DNS. If you won't specify nameserver's ports Truemail will use default DNS TCP/UDP port 53. Accepts one ore more values separated by commas. By default Truemail uses DNS gateway from system settings.
