Junk email filtering service
JunkMailFilter.com claims to have the most advanced Spam and Virus Filter on the planet. They use all the tricks in the book and then some. The cool part is that they give free junk mail filtering for nonprofit organizations:
Nonprofit orgs waste a lot of time and money every year deleting spam and viruses.Most solutions are expensive and just plain don't work. The way I see it - I'd rather nonprofit employees spend their time doing good work rather than spending hours every week deleting unwanted email. And - I have a system that solves the problem.
The way it works is that your email comes from the internet into my servers. I process it - and send the good email onto your existing email server. So - nothing on your end has to change. Once this is set up - everything is the same - except the spam and viruses are gone.
