That was solved 6 years ago. You let them use port 587 instead of 25. http://www.faqs.org/rfcs/rfc2476.html

How many MUAs default to port 587?

The one I use daily does.

How many even know about 587 and give it as an option other than fill-in-the-blank?

Setting up authenticated SMTP in most MUAs is an order of a magnitude more complicated than changing port 25 to 587 anyway.

...back to the computer literacy requirement again... How many support calls you get by requiring 587 instead of 25?

I don't know, but we get a lot of support calls about spam and viruses, so if we can cut back on those .. But the subject is still spot-on: not moving customers to port 587 for mail submission because it would be "too hard" is laziness on the part of the ISP. Mike.
