How E-Mail sends binary attachments (such as .exe files) ?

Hi,

What kind of a encoding does E-Mails use when sending binary attachments ? Is it base64 encoding ?

Thank you.

Yes, it is base64 although SMTP supports other encodings such as quoted-printable and 7bit.
Take a look at binary-to-text encoding list on Wikipedia for other encoding types.
