try reading the help file? it is really quite easy to setup. If you have other accounts like hotmail or email.com, i would suggest mrpostman. Development is ridiculously slow, but it's at a stable level atm and works for a number of services. It is uses more resouces than should be necessary (~20MB RAM, no CPU essentially) and is based on JAVA, so is completely cross platform (though I still can't get it working on my headless debian box, but i dont' even know if i have java working there)
