The problem is that you need to have port 587 set up without TLS_on_connect to
support clients that cannot use port 25, so you cannot use that with Outlook.
Outlook insists on TLS_on_connect for anything other than port 25, so you need
another port if you are need to support Outlook. Port 465 seems to be the
answer if you have that option. Once again it is MS and Outlook which are at
the root of a problem!
