  • Updated gem development dependencies

[2.2.0] - 2020.12.01

Ability to use fail fast behavior 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.

Added

  • Added Truemail::Configuration#smtp_fail_fast
  • Added Truemail::Validate::Smtp#smtp_fail_fast?
  • Added Truemail::Validate::Smtp#filtered_mail_servers_by_fail_fast_scenario

Changed

  • Updated Truemail::Validate::Smtp#attempts
  • Updated Truemail::Validate::Smtp#establish_smtp_connection
  • Updated gem documentation

It's a configurable and not required option:

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

Thanks to @wikiti for timeout reports.

[2.1.0] - 2020.11.21

Collecting only unique ip-addresses for target mail servers. This update reduces email validation time for case when remote server have closed connection via avoiding connection attempt to server with the same ip address.

Changed

  • Updated Truemail::Validate::Mx#fetch_target_hosts

[2.0.2] - 2020.11.14

  • Updated gem documentation

[2.0.1] - 2020.10.20

Changed

  • Updated gem development dependencies

SMTP connection errors: invalid HELO hostname (localhost), duplicate HELO (verifier domain). Thanks to @nenoganchev for report.

Changed

  • Updated Truemail::Validate::Smtp::Request#run
  • Updated Truemail::Validate::Smtp::Request#session_data
  • Updated Truemail::Validate::Smtp::Response

Now helo is a Boolean instead of Net::SMTP::Response instance. It was changed because helo is sending during SMTP-session initializing (Net::SMTP.new.start), and helo is always true if session up is okay. Also hello response won't logged as error if it happens. Example of Truemail::Validate::Smtp::Response instance from 2.x version.

#<struct Truemail::Validate::Smtp::Response:0x00007fa74704cd10
  port_opened=true,
  connection=true,
  helo=true, # Returns Boolean instead of Net::SMTP::Response instance
  mailfrom=false,
  rcptto=nil,
  errors={:mailfrom=>"server response timeout"}>

Added

  • Configurable option: validation for whitelisted domains only.

When email domain in whitelist and whitelist_validation is sets equal to true validation type will be passed to other validators. Validation of email which not contains whitelisted domain always will return false.

Truemail.configure do |config|
  config.verifier_email = 'verifier@example.com'
  config.whitelisted_domains = ['white-domain.com']
  config.whitelist_validation = true
end

Email has whitelisted domain

Truemail.validate('email@white-domain.com', with: :regex)

#<Truemail::Validator:0x000055b8429f3490
  @result=#<struct Truemail::Validator::Result
    success=true,
    email="email@white-domain.com",
    domain=nil,
    mail_servers=[],
    errors={},
    smtp_debug=nil>,
  @validation_type=:regex>

Email hasn't whitelisted domain

Truemail.validate('email@domain.com', with: :regex)

#<Truemail::Validator:0x000055b8429f3490
  @result=#<struct Truemail::Validator::Result
    success=false,
    email="email@domain.com",
    domain=nil,
