A few times I had a situation like this:

  1. I sent an email to foobar@example.com.

  2. For this email, I received a delivery failure report, giving reasons like "550 5.1.1" (user unknown) or "552-5.7.0" (security issue).

  3. In this delivery failure report, a different email address is mentioned

    Mail delivery to the following recipient has finally failed:

    john.doe@example.edu

    or

    Final-Recipient: rfc822; john.doe@example.edu
    Original-Recipient: rfc822;john.doe@example.edu

So, I assume that the owner of foobar@example.com decided to forward emails to john.doe@example.edu. But I only learned about this email address thanks to an error. This could be a privacy problem for the recipient.

Is it standards-compliant to disclose the forward email address in this context? If yes, is there a way to prevent such a disclosure?

When users request /, I want to redirect them to /en or /de, depending on their preference specified in the HTTP request header Accept-Language.

I guess this is easy with server-side scripting, but I need a .htaccess solution as it has to work for a static site.

What I tried:

Users get their preferred language, but they don’t get redirected.

Users get redirected, but they don’t (necessarily ‡) get their preferred language.

(‡ Neither does it assure that the language has a quality value greater than 0, nor does it find the preferred language in case both languages are specified with different quality values.)

Is there a solution for this?

Whether making content negotiation redirect somehow, or allowing to check/compare quality values in the RewriteCond directive, or something totally different.
