http://www.ISAserver.org ------------------------------------------------------- Hi John T, Unfortunately, this is Imail 8.22. It works fine locally on it's private IP. It used to work with ISA 2004. However, I recently changed datacenters and built this new firewall and that's when it arose. Thanks for taking the time to respond. Any other ideas I might try?
