Well right now I have records in the DNS that looks like this. Two MX records, one has a priority 10 and is mgw1.ispdomain.com and one that has a priority 20 and is mail.domain.com. Then I have a HOST record that points mail to the IP of the Imail server. Should I point the HOST record for mail to the IP of the IMGate box? It looks like mail is getting sent directly to the Imail machine.
