but from outside the local network (using a windows box) it fails with:
"Could not open connection to the host, on port 25: Connect failed.
Several reasons come immediately to mind, the smtp server isn't listening on an outside interface, a firewall is blocking the traffic (either your company's, locally, and also many isps also block port 25 traffic), etc.
I am somewhat curious how you are receiving email if smtp is not available (since sending email (25) uses the same port as delivering email (25), unless by "receiving" you mean getting email from the server via pop3/imap/mailspool.)
Hope that helps.
