I am trying to migrate my exchange 2003 setup to new hardware. I have been using http://www.msexchange.org/tutorials/Migrating-Exchange2000-Exchange-2003 -Hardware.html and http://support.microsoft.com/default.aspx?scid=kb;en-us;822931 as guides on how to do this. I have brought up my destination exchange server and have started the replication of the public folders. What I am seeing is that the replication is not going straight across from the source server to the destination server. Instead, the source server is trying to send an email through my mail gateway to the destination server. I have been looking for some small step or configuration I have missed but both sets of directions seem pretty straight forward. Any ideas on what I may have done wrong? Thanks, steve
