I am viewing multiple logs like this:


Feb 24 07:00:32 srv postfix/qmgr[31908]: 3856E176C95C: from=<>, size=8082, nrcpt=1 (queue active)
Feb 24 07:00:32 srv postfix/qmgr[31908]: 711C1176C88D: from=<>, size=7482, nrcpt=1 (queue active)
Feb 24 07:00:32 srv postfix/qmgr[31908]: E12AD176C937: from=<>, size=11545, nrcpt=1 (queue active)

What happens?

Please help.

.. and... any problem?

Those are probably bounce notices, which are required by RFC2821 to have a null sender address so that they can't "re-bounce."

Thanks for the info.
