C# imap/pop3 mail server

I have searched all over the web for a solution for this situation.
I created an application using a PowerTCP component to receive and change mails(Imap/pop3)
I created a new object for them and now all I want is to create a server*(Mail Server)* that uses Imap or pop3 mails to receive and sends mails with SMTP.
I know that I need to use specific ports for it.
What I want to know is how can I create an imap/pop3 object from my C# object(my class , properties, ext) using c# to send to the client email application (like outlook). I searched a lot for this and found nothing.
I don't want to use any "close" server application for this because that I want to change
Do I need to create it from the beginning or there is any ready to use solution for this.
do you have any suggestion code template ext…

TIA
