gmail is fine... (Score 1)

I set one up for my step-son to use. Only I know the actual gmail password, so he can't log into directly. I also have a forward of all the mail he gets to another account of mine just in case. Lastly, I set him up with Thunderbird using a master-password that he set up which is completely different from the gmail one. In the config I just made sure only people I want emailing him are white-listed, so Thunderbird takes care of unwanted things that will only show up in the gmail interface that I go in and delete periodically.
