Email respond to sender from private email

Hello,
I want to ask if somebody can point me to plugin if exist which does next thing.
I have private email for example johndoe@example.com
and have office@example.com which is official
so, when some email get to official email it get forwarded to private and i want to ask is any plugin that allows me to reply to email using private email to official and sender to get email from official?
incoming :

sender>>>>server>>>private

and what i need is:

private>>>>official>>>>> sender

that should be looks like path of email.
I want to respond to email and avoid showing my private email to sender and to be sent form official email.

Thank you
