I am not clear what you mean by "After this step again the server needs to
send a request asking for some other parameters." Is this step related to
authentication, or to some other aspect of the email protocol you are

achieve this in plain.c?

the client the server needs to ask for another parameter and if the client
sends that x parameter, the server should receive it. Is it possible to
implement in plain.c? if it is possible can you send a snippet?

A challenge-response (multi-step) mechanism, such as OTP or DIGEST-MD5,
would be better place to start.
