Just because they don't provide your connection to the internet doesn't mean they aren't an ISP. The definition of ISP has changed, or evolved over time. Clearly, freemail providers fall into that category nowadays. As mentioned, there are clear reasons for what ISP's, and mail server admins, do what they do. I remember when yahoo was an open relay and no ISP or mail server blocked ports from their service. The result was the invention of spam. This group is against spam. You don't have to use the product, but others do, and if you don't like that, complain to them. Just my $0.02
