  Emails are used every day for communication, and many countries and
organisations mostly use email for official communications. It is highly valued
and recognised for confidential conversations and transactions in day-to-day
business. The Often use of this channel and the quality of information it
carries attracted cyber attackers to it. There are many existing techniques to
mitigate attacks on email, however, the systems are more focused on email
content and behaviour and not securing entrances to email boxes, composition,
and settings. This work intends to protect users' email composition and
settings to prevent attackers from using an account when it gets hacked or
hijacked and stop them from setting forwarding on the victim's email account to
a different account which automatically stops the user from receiving emails. A
secure code is applied to the composition send button to curtail insider
impersonation attack. Also, to secure open applications on public and private
devices.
