PHPMailer changing Content-transfer-encoding

Question

I'm developing a program which uses PHPMailer.

I want to change "Content-transfer-encoding" in header of email.

Here is my eml format email header sample.

MIME-Version: 1.0
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: quoted-printable

BUT I want to change "quoted-printable" to "base64"

MIME-Version: 1.0
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: base64

Is there any solution change encoding??

Answer 1

You could try reading the documentation , or looking at the source code. In short, do this:

$mail->Encoding = 'base64';

But I wouldn't advise doing this; base64-encoded HTML bodies make you look like a spammer.
