SCaptcha 2.3.1

Released 2 October 2026

Disposable email server imports

  • Disposable-email MX hostnames can now use the DNS maximum of 253 bytes. Long, valid mail-server names no longer fail because the database column is too short.
  • SCaptcha trims imported MX entries, converts them to lowercase, removes duplicates, and skips entries that are not valid hostnames.
  • If the upstream list is empty or contains no usable hostnames, SCaptcha keeps the previous valid list.
  • Updates from earlier SCaptcha 2 versions adjust the hostname column automatically.
