Catch-all domains

A catch-all (accept-all) domain accepts RCPT TO for any local part. Nexiphor marks these addresses as Risky, not Valid — the mailbox may exist, but bounces are still possible.

For outbound campaigns, use the Valid + Safe Catch-All export preset (score ≥ 70 on reputable hosts like Google Workspace or Microsoft 365). Unknown verdicts are refunded; we do not guess when the provider withholds a definitive answer.
