That's all very well to be standing on your high horse, but when you're locked
into a plan with a dodgy ISP for a number of months, and their SMTP servers
are dodgy, I think you might feel differently.
Non mainstream folks should not have to pay for business plans to get the
functionality of the internet that has been available all along. It is of
course within the rights of an ISP to block particular ports, but that does
not make it right. 12 month contracts and monopolies in particular sectors make
this issue particularly pertinent.
