• ErrorSPF_TOO_MANY_LOOKUPS

  The SPF record needs more than 10 DNS lookups.

  RFC 7208 limits evaluation to 10 lookups from include, a, mx, ptr, exists and redirect. Above the limit receivers return a permanent error.

  Recommendation: Reduce the number of lookups, for example by removing includes for services that no longer send mail.
