PopPeeper is great! I've used it for years. I use Mailwasher for blacklisting spam in my regular OE accounts. I use PopPeeper for checking my hotmail, yahoo, and Juno junk accounts. (My first ISP was Juno and I've just kept it active, but don't use Juno anymore.)
You can send/receive and all that with PP, but basically I just use it to check those old accounts to keep them active, and then delete any emails that are junk. My ISP (RoadRunner) still has a very small limit for my inbox, so I also use yahoo and hotmail as backup when friends need to send me larger email attachments.
The people at PP are on the ball. When yahoo and hotmail change their protocols, it isn't longer than a day or two before PP has a fix to get it working again.
