A business domain is part of identity. If someone impersonates the sender, customer trust and mail deliverability suffer.

Protection layers

SPF lists authorized sending servers, DKIM signs messages, and DMARC defines policy for messages that fail checks.

BIMI helps recipients recognize the brand, while anti-spam filters reduce the impact of abuse.

Monitoring and response

Watch bounces, DMARC reports, SpamBox quarantine and customer signals.

Hostilla.pl uses multiple layers of mail filtering and domain security.
