I'm running an Exchange 2007 SP1 server. While installing a helpdesk app it asked for IMAP or POP to send emails out. I wasn't using either on my Exchange server, so I set them both up. I can receive email externally and internally from my workstation and physical servers with both POP3 and IMAP and send via SMTP, but not on the Windows 2003 virtual server I setup in VMWare (1.0.4). I ran TELNET MyVirtualServerName 25, connected, did a HELO and it hangs eventually saying "Conneciton to host lost.". I tried it on another virtual machines (located on the same physical VMWare box) and it worked, but not on all virtual machines. All virtual machines are R2 SP2... Any ideas?
