Besides being tagged BETA, which requirements were you looking for with SCRYPTmail that were not met?
For starters, its not anonymous...they have to store traceable information to offer password reset and 2xF auth. Also, there is the self registration. Although self register is convenient, there is no controll as to who registers and what they use the emails for. Even Safe-mail figured this out while implementing backdoors for LE
Like Safe-Mail, there will come a point when LE will take control of this one too, then they will probably also post that 250K accounts violated their terms etc......My question, How do they know those accounts violated their policies other than reading the emails?
