Hi @goodale, thank you for your report!

This email address is actually valid by RFC, as a domain without a top level domain is considered a local domain name. Other email address validation libraries also return true for a similar address:

However, JMail recognizes that this type email address should usually be considered invalid in real-world use. You should use JMail.strictValidator().isValid() in order to achieve what you want. For example:

// This returns true as you noticed
JMail.isValid("agadgf@fsaf");

// This returns false, which is what you desire
JMail.strictValidator().isValid("agadgf@fsaf");

The validator returned by strictValidator() includes these rules:

disallowIpDomain()
requireTopLevelDomain()
disallowExplicitSourceRouting()

If you don't want all three of those rules you can just include the one that requires a top level domain:

// This returns false for your email address as well
JMail.validator().requireTopLevelDomain().isValid("agadgf@fsaf");

And you can also check the README for more information on all of the available rules.
