git-send-mail and Content-Transfer-Encoding

[onemoresuza]

Does addy change the Content-Transfer-Encoding header when sending from an alias?

I'm asking this, because, no matter which --transfer-encoding option I pass to git-send-mail --- 8bit, 7bit, base64, auto ---, every email that reaches a mailing list has its Content-Transfer-Encoding header is set to quoted-printable.

Each email forwarded by addy.io is sent on as an entirely new email, Laravel is using Symfony mailer to send the messages. Yes Content-Transfer-Encoding is automatically set as quoted-printable.

Unfortunately it doesn't look like there is an easy way to set the encoding in Symfony mailer, it also looks like the only supported encoding options are quoted-printable, base64 and 8bit - https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/Mime/Part/TextPart.php#L66

If I can find a good way to implement this I'll include it.
