I am migrating from GW12 to GW 14. The destination server is OES 11 sp1 VM running on a XEN host. I successfully migrate and upgrade the domain and the post office but can not get the gwia to communicate with the MTA. I have even deleted the migrated GWIA and created a new one with no success. Any help will be appreciated.
GWIA connect to the MTA to receive messages but the Send connection does not start.
