I am using Gmail since very long time and I always love it because it has automatic virus detector which detects the virus on attachments.
The problems that are face is that it does not work in bad internet connection. The user interface is fabulous, I love the drag and drop features to attach a file. It also indicates whether the received message is encrypted or not.
You can also name your received message so at in future we can easily find it. The customer support is nice, I am only telling you about contact through email because I only contact them through email.
I think you should use Gmail.
