v2.4.0: Feature/MxBlacklist validation layer

MX blacklist layer provides checking extracted mail server(s) IP address from MX validation with predefined blacklisted IP addresses list. It can be used as a part of DEA (disposable email address) validations.

[Whitelist/Blacklist] -> [Regex validation] -> [MX validation] -> [MX blacklist validation]

Example of usage:

require 'truemail'

Truemail.configure do |config|
  config.verifier_email = 'verifier@example.com'
  config.blacklisted_mx_ip_addresses = ['127.0.1.2']
end

Truemail.validate('email@example.com', with: :mx_blacklist)

=> #<Truemail::Validator:0x00007fca0c8aea70
 @result=
  #<struct Truemail::Validator::Result
   success=false,
   email="email@example.com",
   domain="example.com",
   mail_servers=["127.0.1.1", "127.0.1.2"],
   errors={:mx_blacklist=>"blacklisted mx server ip address"},
   smtp_debug=nil,
   configuration=
    #<Truemail::Configuration:0x00007fca0c8aeb38
     @blacklisted_domains=[],
     @blacklisted_mx_ip_addresses=["127.0.1.2"],

     @not_rfc_mx_lookup_flow=false,
     @response_timeout=2,
     @smtp_error_body_pattern=/(?=.*550)(?=.*(user|account|customer|mailbox)).*/i,

Ability to use custom DNS gateway. Thanks @le0pard for the great idea and @verdi8 for feature request.

  # Optional parameter. 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. By default Truemail uses DNS gateway
  # from system settings and this option is equal to empty array.
