Greetings! We are trying to work out an alternative path for mail intended for our email-to-fax system. Mail is addressed to a fax number at the fax server. The server receives it through an Outlook Express client, renders it, and dials the fax number in the address.
The snag is, the mail must come in from outside our network. This works fine when it comes directly to the IL location. However, we have had a couple of long outages where Illinois has no internet connection. (Our office can still reach the internet if we route internet traffic through our WAN and use the New York internet connection.) We have an MX record for the NYC location with a priority lower that of the IL location (tests out ok - we can see SMTP traffic entering the NYC internet firewall when we watch traffic for that firewall policy). Internet firewalls at IL and NYC are both the same model of Juniper SSG-series. Both have the same policies for allowing mail to the fax server. WAN routers are all AdTran NetVanta 5305 (just in case this is a factor). HERE IS THE PROBLEM - when the mail is routed through NYC, it never makes it to the server in IL. We run trace route jobs from various systems from the NYC location (including console sessions from the firewall), and the route steps shown are as they should be. The NYC firewall can ping the server in IL. We "undo" testing procedures to use the IL internet connection, and all the test mails come in to the server. Any idea what could be blocking mail traffic coming in through NYC? Thanks... -- Richard D. McClary Jr Infrastructure Architect, Information Technology Group ASPCA(r) 1717 S.
