Postfix error - some files seems not owner+group+world executable but they are

hi....I installed postfix 2.8.0, and I tried to send a test email, but nothing happend, just my server got stuck. When I started postfix, this message displayed:

postfix/postfix-script: warning: not set-gid or not owner+group+world executable: /usr/sbin/postqueue
postfix/postfix-script: warning: not set-gid or not owner+group+world executable: /usr/sbin/postdrop

I thought it is nothing, but I think this is what my test mail was not sent. I looked at these files but they are owner+group+world executable. I don't know where is the problem. Please help me.

Thanks in advance.

Ohh...I found answer....plzzzz how to delete this?
