Mail to South Africa from outside our company enters in North America and then gets sent via a VPN tunnel. The configuration consists of Exchange 2003 Bridgehead servers on both sides. We originally configured X.400 connectors, but now have SMTP connectors with a lower costing. Mail congests seriously on the Server in NA causing mail to be delayed for up to 12 hours before reaching ZA. At times the queue backs up to approx. 3000 messages. Any ideas, suggestions, monitoring tools, etc will be greatly appreciated. Regards -Harry
