I'm trying to upgrade an old mail server that's running SM 4.3 on a 32 bit Windows 2003 Server Webhost Edition. I want to move all the mail accounts over to a new server running SM 12 or 13 on 64 bit Windows web server 2008. I have been told that SmarterMail has no migration tools for going from an old version to a new version. I have to install the old version on the new server, move the accounts and then do an upgrade to the new version.
The problem I'm having is after I install SM 4 on the new Win 2008 server and test it (before moving any accounts), I cannot receive mail. I can send it, but all incoming mail is rejected. Yes, I have the MX records set up. If I do a port scan on the machine's IP, it shows all the mail ports are closed. I have totally disabled Windows firewall and have all mail ports open on my network's firewall.
I'm wondering if this is just a case of SM 4 not being compatible with 64 bit Windows.
As a test, I added the Windows SMTP Server Role in the Server Manager and scanned the ports again. After I installed that, port 25 showed it was open. So, I know it's not a firewall issue.
Any suggestions would be appreciated. I've been pulling my hair out on this one for quite some time.
