It will not make any difference at all. Files in the flush directory are used for "postqueue -s domain" or "sendmail -qR domain". > Will preemption of messages take place or will it effect the delivery > process ? None of the above. Do not list local destinations in fast_flush_domains. In fact, it is a good idea not to change parameters until you have been using Postfix for a considerable time. Wietse
