Got a bit of a problem... Exchange 2003 works fine internally - but when I try through the internet, nothing happens. I try telnetting to port 25 of my router and when config'd to the IP address of the current email server its fine - but when it points to the IP address of the Exchange server - its no go. Like I say - internally its fine - I can telnet to the 192 address.
Any ideas? I'm getting frustrated.
