What is the maximum allowed size of Mail?

I am making an application in which I am taking some information from user and send that information to an email account.In the email, I attach the following:

-About five images

- A ~5 minute audio file

- The message body

Is it possible to send all the information in one email? What is the maximum message size?

If anyone has a better solution for it, pl开发者_运维问答ease provide some source code or a demo for this.

Thanks to all

Mail doesn't have a limit, but an ISP would. A realistic limit for most people is probably 10MB, though you may want to keep it more around 5MB and split things across emails...
