Ruby email encoding and quoted-printable content

Question

Is there a straightforward way to coach TMail to make the body encoded with "quoted-printable"? I only see methods in there for decoding content like that, not creating it.

Answer 1

Are you just using TMail, or are you using it with ActionMailer? It looks like TMail itself does not have the ability to encode as quoted-printable. However, it looks like ActionMailer does have this ability.

It looks like TMail allows you to set the Content-Transfer-Encoding header as follows :-

mail = TMail::Mail.new
mail.transfer_encoding = "quoted-printable"

But it looks like this doesn't actually encode the body.

You can see ActionMailer setting this header here. quoted-printable seems to be the default for ActionMailer.

ActionMailer has the ActionMailer::Quoting::quoted_printable method to encode the body as quoted-printable. Maybe you can make use of this...?
