YMail spam filters use Bayesian techniques. You can indicate which messages are spam and which are not YMail (even before you to download to your computer!) And every time its filter matching set. After a few days it will be able to sort mail quickly and efficiently, without input.
YMail can also be used as a mail scanner - you do not have the e-mail use part of the program, just use YMail preview and automatically delete spam before downloading into your regular e-mail software.yMail a spam cleaner and standalone e-mail client.
For safety reasons YMail not open or display attachments automatically. It warns you when you open attachments and to try and flatly refuses to run executable files.
YMail not the HTML e-mails, so that there is evidence from spam running and loads web bugs when you preview (This is a trick they use to confirm your email address is valid)
If you DO receive an HTML-formatted e-mail with a special link to click can open the message in your default browser, but I recommend against this unless you know the sender and what they send.
YMail will strip out all HTML and displays the text in the preview window anyway, so you have a pretty good idea of the content and you will not see flash-flash-lights or banners.
Since you can easily tell where should YMail your message store, it is possible to run YMail from a removable drive. Nothing is stored on the host computer, it is completely independent. Therefore, you can take YMail and simply copy back your mail folders on your hard drive when you return.
