I am still in the process of a swing migration from Exchange 2003 to Exchange 2007 this weekend. I have all of the user 120 mailboxes moved to the Exchange 2007 box. My Outlook, Entourage clients are connecting successfully. I have the one Exchange 2007 box and the Exchange 2003 swing box. I have removed the connectors between the 2003 and 2007 boxes. Here are the items I still need help with:
1) When I opened up the firewall to allow incoming and outgoing SMTP traffic, I noticed the mail queues were being flooded with traffic from outside? our network. This is strange because I only allow port 25 traffic in (via a Watchguard firewall rule) from Postini (our provider that cleans up the mail before it gets to us). I need to make sure that our server is not an open relay. How does the receive connector need to be set up to be safe? There are currently 2 receive connectors listed.
2) I tried to import our Geotrust SSL certificate in the command shell. It imported successfully, but could never attach it to IIS, because the command shell said the private key was missing. I tried adding it the 'ole fashion way through IIS, but Exchange doesn't know about it and OWA will not work even when I change the internal and external URL settings to https://owa.biltmorebaptist.org/owa
. This type of URL (formerly https://owa.biltmorebaptist.org/exchange
) used to work in (via DNS entry) and outside of our network. This SSL issue is also affecting all of our Windows Mobile Smartphones and PDA Phones.
3) Can you use the IMF and anti-spam settings without a separate Edge server?
Any help you can provide would be much appreciated. I have been using 2003 for years and think I have got in over my head with 2007. But I'm too far along to go back now.
