I need to block all outgoing smtp traffic except for the mail server.. I implemented the following
access-list 102 permit tcp host 10.x.x.x any eq smtp
access-list 102 deny tcp any any eq smtp
access-list 102 permit ip any any
I applied it the interface all the hosts are connected to
ip access-group 102 in
But its still sending mail from another ip within the network to the outside world.. what am I doing wrong?
