I'd like to set up a "polling" situation so the mail server inside the FW can grab mail from the MX'd server outside the firewall. It appears that "fetchmail" may do this with newer sendmails that are configured to use ESMTP. The other problem is the IP # that the inside server has will be dynamic (assigned by the firewall) WRT the outside. It seems this will cause validation problems as there will be no DNS mapping. Was wondering if anyone had any recomendations on this? TIA - Frank \\\\////\\\\////\\\\\////\\\\\////\\\\////\\\\////\\\\////\\\\////\\\\////\\\\ Frank Terhaar-Yonkers Cisco Systems, Inc.
