body->size.bytes is the size of the first MIME body part, or the size of the entire message body for a single-part or non-MIME message.

The way that this is calculated by the server is by parsing the message. If you are uploading a message from the client, you are sending the message as a text string, and thus you must parse it yourself.

The c-client library has routines that will do this.

How can a client determine BODY.size.bytes prior to uploading the message to the server? We are attempting to write a client such that the client will know the size of BODY (in bytes) as it will appear on the server. Once the message has been uploaded to the server, determining the size is simple, i.e.:

BODY * body;
mail_fetchstructure(stream, msgno, &body)
printf("%u", body->size.bytes);

However, we have not been able to find any one value or combination of values the client has access to locally that will equal size.bytes, as demonstrated in the above code. How does the server determine the size of the body? Is there any way a client can calculate that value locally, so that the size on the server will be known before actually uploading to the server?

Thanks
