I may have not be clear enough. The processing speed of the filter depends on the size of the message. What I suggest is that I slow down the message recipient process (add some wait time when the filter receives RCPT from Postfix) when the queue size of the filter becomes too large (soft-limit). Currently there is only a hard-limit. Martijn
