Email domain validation 1.3.0

Improves email validation in the following ways:

• More extensive typo detection
• Checks the domain-part of an email is "valid" and can receive email (ie has an MX/A record), and then checks any MX records are not listed in the banned email domain list
  • This validation is done via the bundled version of https://github.com/egulias/EmailValidator

Provides a "Test email address validity" (/admin.php?tools/test-email-address-validity) Page to give in-depth reporting of why an email is rejected

• Supports reporting issues if Signup abuse detection and blocking add-on would block the email address during registration
• With XenForo 2.3.4+ this page respects the Perform checks and tests admin permission.

Options

• Admin user edits skip additional DNS-validation of email domains (default: false)
