This was the first implementation but because of a lack of knowlage it was buggy.

We have to use BINARYMIME see

for more info.

Note: As I'm currently quite busy I have no time to implement this so feel free to create a PR.

Why?

With base64 we encode 6Bit as 8Bit so we have 33% bigger E-Mails this is not optimal (with small attachments it is ok but larger ones are too large).
