There is an example in QSHAPE_README that implements delays with a non-responding destination plus smtp_fallback_relay. This might do the job for Postfix < 2.5. Postfix 2.5 has outbound rate limits per destination. http://www.postfix.org/postconf.5.html#default_destination_rate_delay You would use something like /etc/postfix/main.cf: smtp_destination_rate_delay=60 Or some other delay. This delay is enforced by the queue manager. Wietse
