推荐答案

您可能无法执行-通常在主机端引入限制. MIME本身没有设置任何限制，但是由于电子邮件以这种方式通过了可变数量的邮件传输代理，并且每个代理都必须存储和转发每封邮件，因此，它们引入的任何限制将成为总体限制因素. br/>
还值得注意的是，MIME编码(发送这样的附件是必需的)在每个附件上总共增加了大约30％的开销-因此看似5Mb的文件可以变成6.5Mb的附件.

如果可以，请找到另一种方法-也许使文件可供下载并在电子邮件中提供指向该文件的链接.首先，发送大量电子邮件不是一种友好的处理方式-您不知道收件人的连接速度，而且如果您的Internet连接速度很慢，那么发送一封大型电子邮件可能会非常非常烦人.出于任何原因.

You may not be able to - it is generally at the host end that the limits are introduced. MIME itself sets no limit, but since email passes through a variable number of mail transfer agents on it''s way - and each has to store-and-forward each message - any limitation that they introduce will be the overall limiting factor.

It is also worth noting that MIME encoding (which is necessary to send such an attachment) adds up to about 30% overhead on each attachment - so what appears to be a 5Mb file, can become a 6.5Mb attachment.

If you can, find another way - perhaps making the file available for download and providing a link to the file in the email. Sending massive emails is not a friendly way to do things in the first place - you do not know the speed of the recipient''s connection, and a large email can be very, very, annoying if you are on a slow internet connection for whatever reason.
