Review by Michael E. Callahan aka Dr. File Finder
ChoiceMail One by DigiPortal lets you take control of your email. You decide what emails get through. It doesn't sit there and try to filter your email, but it follows some very basic rules. It's a "challenge-response" or "permission-based" system. It works!
ChoiceMail One uses your email address book to create a"whitelist" of the people you want to receive email from.Everything else is blocked. So, if you know me and you send me an email, it comes right through. You, the sender, can't tell any difference. Now, to help take into account "new friends" each time I send an email to someone not in my address book, they are also added to the whitelist. The program also lets me create rulesthat allow other mail to get through even though the sender isn't on my whitelist. For example, I play guitar so I've created a rule that allows any email that has "guitar" in it. Slick.

ChoiceMail One puts all other email in quarantine and sends an email to each sender. The email basically asks the sender to register by going to a Web page and entering their name and email address. They're also asked to say why they're contacting you and to do a little task. Why? Well, because the majority of SPAM is sent out by automated systems and they won't respond to the request or be able to do he task.
ChoiceMail One works! It's reduced the amount of SPAM I receive to nearly zero. Other anti-spam programs take their best guess at what's good and what isn't. ChoiceMail One doesn't guess. I either know you or I don't. You're either human or an automated system.You either respond or you don't. It's that simple. Give it a try. I've tested nearly every anti-spam solution available and this is the one that works for me. Check it out!
