Recent problem posted on the NG:
We do not have a static IP. Our ISP requires that we forward mail to their SMTP server on port 1025 instead of port 25. When I look at the SmallBusiness SMTP connector there does not appear to be a choice for the SMTP port. Is there a way to specify port 1025 for just their smarthost?
The answer (provided by Henry Craven) was:
1. Shut down the Exchange services
2. Go to: %systemroot%\system32\drivers\etc\services file
3. Edit the contents for the smtp service to specify another port number
smtp 25/tcp mail #……
and change it to:
smtp 1025 /tcp mail #…..
4. save the file then restart the Exchange services.
