I need to know in one year who sent at who. I have logs for the year and records are like: Feb 13 06:27:57 mail1-xen postfix/qmgr[8336]: BF683A28247: from=<..............> Feb 13 06:28:13 mail1-xen postfix/qmgr[8336]: BF683A28247: to=<..............> What element I can use to identify who sent at who in the logs files?
