类名称：Mail
方法名：getMessageSize

Mail.getMessageSize介绍

[英]Returns the message size (including headers).

This is intended as a guide suitable for processing heuristics, and not a precise indication of the number of outgoing bytes that would be produced were the email to be encoded for transport. In cases where an exact value is not readily available or is difficult to determine (for example, when the fully transfer encoded message is not available) a suitable estimate may be returned.
[中]返回消息大小（包括标题）。
这是一个适用于处理启发式的指南，而不是一个精确的指示，如果要对传输的电子邮件进行编码，将产生多少传出字节。在准确值不容易获得或难以确定的情况下（例如，当完全传输编码的消息不可用时），可以返回适当的估计。
