We are in a migration from GroupWise 7 to Exchange 2003. All the GroupWise system is installed on Linux SLES 9 servers. The GroupWise Gateway for Microsoft Exchange said the following:

"The owning domain cannot reside on a Linux server, but the Exchange Gateway can still service domains that reside on Linux servers by way of TCP/IP links"

Does anybody has experience with this Gateway when GroupWsie is Linux?
