Mail_Mime Envelope-To header

[ddehning]

Hi everyone,

currently I'm working on a plugin for Roundcube using some functions of Mail_Mime.

At one point (Hooks tested: message_before_send, message_ready) I have to replace the recipient of the mail with another one, so I use

Code Select Expand

$message->get();
$message->headers(array('To'=>implode(',', $recipients)), true);

This code is doing well. But there still is the "Envelope-To"-Header which I can't replace like follows:

Code Select Expand

$message->headers(array('To'=>implode(',', $recipients), 'Envelope-To'=>implode(',', $recipients)), true);

Am I totally wrong? I'm just stuck with this. Can anyone help?

Sincerely
Dominik

What do you mean replace? Roundcube does not set this header.

If it's not roundcube I have to a deeper research.

I change the "to" header and somehow exim or whatever adds the original recipient in the envelope-to header...

Anyhow, thanks for your answer.
