My favorite feature of MEO Encryption is that you can configure it to use any SMTP account, then the software will get the email encrypted and send it directly to you. There are only two encryption algorithms available – one is a lightweight algorithm (for fast encryption) and the other is a strong encryption algorithm (for slow encryption). Please choose any one depending on your needs.
