When I enable packet filtering, recieving mail immidiatly stops, though I still can send mail. I created packet filters for ports 25 and 110, according to scenario, but it doesn't help. I need more detailed instructions. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: nick@xxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ********************************************************************** Disclaimer: This e-mail contains proprietary information some or all of which may be legally privileged.
