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.


Regards

Andreas

this is generated from dovecot i would say an from <> are susually bounces
has nothing to do with postfix since it does only what it should do
pickup the message and try to deliver
