I have found a hint.

• /etc/ssmtp/ssmtp.conf:root=hjoon0510@gmail.com ---> username@gmail.com

  
  $ cd /etc
  $ grep -R "hjoon0510@gmail.com" ./*
  ./ssmtp/ssmtp.conf:root=hjoon0510@gmail.com
  ./ssmtp/ssmtp.conf:AuthUser=hjoon0510@gmail.com
  ./ssmtp/msg.txt:To: hjoon0510@gmail.com
  ./ssmtp/msg.txt:From: hjoon0510@gmail.com

```bash
# The user that gets all the mails (UID < 1000, usually the admin)
root=username@gmail.com
