SMTR-602 — Unknown client - access denied


A (alert)

Message text

Non-matching %s (%s), rejecting


The client connecting to the proxy has a reverse DNS entry, but the name has not the client's IP address in DNS.

If the client is a legal MTA trying send you a legal message, please, contact client's domain administrator to correct the DNS entry.

If you want to allow such clients to access your proxy, specify the UNMATCHING-CLIENT configuration directive.
