Hi Everybody, i find a abnormal log in maillog file for postfix. a user can send email , non ip address and non from username present in the log. how can i reslove that ? [root@mail ~]# less /var/log/maillog |grep 608D536DA9C |more May 3 18:10:57 mail postfix/pickup[23046]: 608D536DA9C: uid=1000 from=
The mail is submitted locally, so you can't get a IP address.The empty sender may be because of a bounce which require the sender to be empty.
You should check who is using the user ID 1000 on your system and why the mails are created.
