Have downloaded this on OSX and OS 8.6. The app works as advertised. THANK YOU for finally ridding me of Yahoo! and Hotmail web interfacces for my email! Now I can use my own email client's ilters to rid me of spam. This great app also allows me to read all of my mail in one place...no more logging into several web-mail accounts just to read emials. If testing continues successfully, then I will thank you with my registration fee. :)
