VG> Now I want delete the mail in mail box. How to do that
I suppose that youre aquainted with RFC 1939, since you've implemented mail get.
So from RFC 1939:
To mark message as deleted
"DELE msg
Arguments:
a message-number (required) which may NOT refer to a
message marked as deleted
"
The example:
"Client: DELE 1"
Server may respond in the following way
"Server: +OK message 1 deleted"
or
"Server: -ERR message 1 already deleted"
