Honestly, you sound exactly like the people 15 years ago or so when we
figured out that open relays maybe weren't such a good idea.  Or when ISP's
finally cut off the last of their UUCP clients.  Lots of wailing and
gnashing of teeth over "don't tell me how to run my server/network/raise my
kid" in the face of overwhelming evidence that things had changed and were
never going to be the same.  This thread has gone on for a few days now and
no one has presented a single rational reason why you or your customers
can't simply configure your/their mail server to relay through the ISP's
mail server.  Just like how sometime in the 90s you had to stop picking SMTP
servers at random and start using your provider's (or run your own), things
have changed, we all must adapt.

And blocking port 25 isn't going to put *anyone* out of business.  The
percentage of clients who even know it's being done, much less care enough
about it to leave and go elsewhere is so miniscule it's laughable.  I'm sure
you could build a nice niche business catering to that tiny minority, and
probably be successful doing so.  Just don't complain when you find yourself
effectively RBL'd off the 'net, just like those like-minded people who
steadfastly maintained their open relays...
