Nothing to worry about, Mixos. When it comes to server security, they are completely useless. All you can do is either continue using them, and accept that there is a high probability that at some point your email account will be hacked, or change to a more secure email provider, which will probably mean paying for it. As SatCure pointed out on another thread, you get what you pay for. If you pay nothing you get zero.
