How can I send email attachment without using an additional library in Perl?

Question

Hey, I was wondering if there is a way to attach files (specifically .csv files) to a mail message in Perl without using MIME::Lite or any other libraries.

Right now

Answer 1

you can specify the mail-headers as :

Content-Type ie: image/jpeg; name="file.jpg"
Content-Disposition (ie ) attachment; filename="name.jpg"
Content-Transfer-Encoding (ie) base64

Look at an email sent with an attachment, that should help you out.

the trick is multipart boundaries.
