This allows modifying the recipient object beyond approval. Before, it was
always moved to the transaction pool, thereby invalidating the original returned
pointer. This way, the data_calback and context can be set at a later time,
e.g. when the DATA command is being processed. This makes a choice between
LMTP-style and SMTP-style replies to the DATA command a bit easier to handle.
Also, the recipient is entirely allocated on a single pool between the client
and server side, which should improve memory consumption a little. As a bonus,
this removes the need to have dummy DATA callbacks.
