Remember "horses for courses", the SMTP protocol used between servers on port 25 is a protocol that requires responses based on logic and state. Shell script is not the language for trying to do this in this situation. You would have better success with C, C++, Java, Perl or Python.
SMTP is an open protocol and you are welcome to use it, as all mail-transfer-agents do.
Also, consider why are you trying to re-invent the wheel, projects such as postfix do an excellent job of managing SMTP both outgoing and incoming in a very flexible manner, allowing you to concentrate on what you are trying to do rather than the nitty-gritties of the SMTP protocol.

of the sender and to is the email address of the recipient. When a complete email is read from STDIN, from and to are only used in the SMTP
