v1.6.2

• Fix bug where IPv4 addresses with non-arabic numerals would incorrectly be considered valid. (Thanks @harrel56 for reporting!)
• Fix bug where IPv4 addresses with extraneous leading zeros would incorrectly be considered valid. (Thanks @harrel56 for reporting!)
• The requireValidMXRecord() validation rule now correctly fails validation for domains that use a "Null MX" record. (Thanks @elmolm for contributing! 🎉)

v1.6.1

• Fix bug so that email addresses that end in a dash - character now correctly fail validation with the reason FailureReason.DOMAIN_PART_ENDS_WITH_DASH instead of incorrectly returning FailureReason.ENDS_WITH_DOT. (Thanks @tbatchlear for reporting!)

v1.6.0

• Add a new rule requireAscii() that considers an email address containing non-ASCII characters to be invalid. (Thanks @frodeto for suggesting!)
• Add new property isAscii() on Email objects that returns if the email address only contains ASCII characters or not.
• Add option to strip quotes within the local-part of an email address when normalizing the address with the normalize() method. (Thanks @tdelaney-leadiro for suggesting!)
  • This new option will remove quotes if the email address would still be valid and semantically the same without them.
  • To enable the option, either:
    • Call the normalize method that takes a boolean as the parameter, and use true. Example: email.normalize(true)
    • Set the -Djmail.normalize.strip.quotes=true JVM property at runtime, and continue to use the normalize() method without parameters.

v1.5.1

• Add a new rule requireValidMXRecord(int initialTimeout, int numRetries) that allows for customization of the timeout for DNS lookups. (Thanks @dotneutron for suggesting!)
• Reduce the default timeout for DNS lookups when adding the requireValidMXRecord() rule to an EmailValidator from potentially taking a maximum of 25 seconds to a maximum of 600 milliseconds.

v1.5.0

• Add new method validate(String email) that returns an EmailValidationResult object, containing the reason for validation failure upon failure. (Thanks @bobharner for suggesting!)
• Add new ValidationRule requireValidMXRecord() to consider email addresses that have a domain with no MX record in DNS as invalid. (Thanks @lpellegr for suggesting!)
• Fix bug where an email address that ends with a comment that is missing the closing parentheses were incorrectly considered as valid. For example: test@test.com(comment

v1.4.1

• Add new ValidationRule disallowObsoleteWhitespace() to consider email addresses with obsolete whitespace as invalid. (Thanks @PascalSchumacher for suggesting!)

v1.4.0

• Add new normalized() method on the Email class to provide a way to get a "normalized" version of an email address (the address without any comments or optional parts).

v1.3.3

• Fix bug where invalid characters in the domain could result in an IllegalArgumentException instead of returning false. (Thanks @PascalSchumacher for reporting!)

v1.3.2

• Fix bug where domain names that contained an emoji would be incorrectly invalid. (Thanks @Autom8edChaos for reporting!)

v1.3.1

• Improve equals() and hashCode() methods for Email and TopLevelDomain
• Fix inconsistencies in some Javadocs
