Rated 5 out of 5 stars

Very nice and fits the bill perfectly. I have several email accounts, one of which is my home email that I monitor while at work. Thunderbird just does not have enough "defaults" to handle things nicely and I cannot tell you how many email chains I have going to my home email now that are work related. This product does the job in a clean and easy way. If you click on the Send, Reply, Reply/all, or Forward button, you get an instantaneous drop down menu that forces you to pick the correct "from" address to use. You must pick it before you can type any further. It is also color coded which is the icing on the cake. Thanks again. Kevin
