This trace has an insane level of debugging turned on, to the point that syslogd is overwhelmed and is losing messages. PLEASE DISABLE ALL VERBOSE logging. NO "-v" options in master.cf, NO debug_peer_list, ... Please make sure that the /dev/log syslog socket is a "dgram" not a "stream" socket, and that mail logging is not synchronous. Then if the problem persists, report just normal Postfix logging, not the flood of noise from verbose logging. -- Viktor.
