Counting clients in smtpd_client_recipient_rate_limit with XFORWARD
in [Postfix]

From: Patrick Ben Koetter on 19 Mar 2010 03:38 When a message reenters from an instance that uses XFORWARD, for example amavis, will Postfix count the IP used twice and, for example, add that to smtpd_client_recipient_rate_limit? p(a)rick -- All technical questions asked privately will be automatically answered on the list and archived for public access unless privacy is explicitely required and justified. saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/>

Rate limits apply to the real client IP address not the forwarded one, subject to $smtpd_client_event_limit_exceptions. Wietse

It does not apply to clients can send XCLIENT, but it should apply to the clients that are being impersonated with XCLIENT. Once a client is impersonated, the smtpd_authorized_xclient_hosts setting is re-evaluated, and the session runs as if the client just connected (except that an already negotiated TLS session is kept).
