That must be heart-breaking and very frustrating. You've done everything you can do to be a good internet citizen and support all the proper technology, but you're still treated badly.

If I am correct, gmail now defaults to a "don't trust an IP by default" procedure. If enough people get your emails in a spam folder and mark it as not being spam, the system will start trusting the IP address. It also has to do with volume.

This might be a good service offering.

If someone could operate a few hundred gmail accounts, they could let people send them messages and mark those messages as not being spam in order to train the filters.

Such accounts would be permanently disabled. Spammers have been trying to use sock-puppet networks for years.
