Look carefully at that question and find the logic error.
.......
In case you missed it, the customer purchased 'IP' service, not 'ISP mail
service'.

If the customer is purchasing IP only service, then they need to either purchase the *right* kind of IP service to operate their own ISP services off that connection, or they need to purchase ISP services from another vendor and then use that vendor's smarthost. If the company they purchase IP services from blocks outbound port 25 except to their own smarthost, then the customer needs to buy ISP services from a vendor who offers mail services on an alternate port, or use the IP provider's smarthost. This is not rocket science here.

The days of "I'm not an ISP but I play one on my residential-service dynamically allocated IP connection to the Internet" are over, just as the days of open relays are over. Adjust, adapt, and move on.
