We recently migrated a client to Windows 2000 and are using the SME 5.2 server, among other duties, as the mail server. We replaced an Exchange Server, chalk another one up for Open Source, and are having some trouble with the latency of interoffice emails arriveing to the Outlook client. The latency can reach 4.5 minutes. How can we check to see if the messages are going out to the ISP and then routed back. If that is happening, how can we make interoffice emials go directly to the interoffice mail box without passing SMPT or collecting 200 secounds.
