This is not something that can be easily done. You probably want to use a library (ex : in python) that will take care of formatting your email according to your needs.
In very brief :
If you want to get an idea of how complex it is to generate an email with a valid attachment, you can use your email client to check the source of an email with an attachment (most email clients have this feature). That should eventually convince you to avoid doing this manually :)
