Upgraded from Smartermail 5 to 7 Enterprise (to enable jump to 12) on Windows Server 2008 R2, using IIS 7.5 for both versions. Running 7 I can log into webmail and send or receive, but cannot send or receive from Outlook (on 3 machines). I can telnet into ports 25, 110 and 2525 (default alternate SMTP port). But Outlook just times out trying to connect. I didn't change any IP addresses or make any other changes to the server. I have rebooted the server and two of my workstations.
