Important notice

At the moment Mail Redirect is not yet compatible with Thunderbird 78.*. I'm still working on a new version that works with Thunderbird 78.*. If you depend on this functionality, please don't upgrade to Thunderbird 78, but stay on version 68 and disable updates, until a compatible version of Mail Redirect is released. If uou already upgraded to Thunderbird 78, and want to downgrade again to Thunderbird 68, please refer to this support question for instructions: Downgrade Thunderbird profile from 78 to 68

The Mailredirect extension for Mozilla Thunderbird and SeaMonkey adds the ability to redirect one or more email messages to one or more recipients.
The feature of email redirecting is also known as remailing or resending.
This extension is an answer for bug #12916.

Who wants this extension?

In office environment there is sometimes a need to forward email with original headers to somebody else. If Forward or Edit as new command is used, headers are very different comparing to original message (other From, Message-Id, Date fields). If you use the Mailredirect Extension headers are not changed, so the recipient of redirected mail has almost the original message. In practice all important headers in redirected message are identical to original one (From, CC, Message-Id, Date).

People who are "sorting" incoming email messages to their company are the first users who would like to use the Mailredirect Extension.
I think every experienced email user will appreciate the Mailredirect Extension.

If above description is not clear for you, take a look at the original one.

How it works

When redirecting email, body and headers are left untouched, so fields like Received:, From:, To: in redirected message are the same as in original one.
However redirected mail differs a bit from original one. A few new headers are added: Resent-From:, Resent-To:, Resent-Date:, Resent-Message-Id: and Resent-User-Agent: which allow to identify redirected mails.
For more details about the redirecting feature and discussion about it, go to bug #12916 page on bugzilla. You can also take a look at RFC 2822 section 3.6.6.

Not all email providers support redirection of messages. Most notably Microsoft does not support it at the moment, probably as a measure against SPAM. I think they do this in error, and also reported this to Microsoft, but unfortunately they haven't changed their policy yet.

If you run into issues with an email provider not supporting redirection of messages, please contact them and see if you can make them change their policy. You can point them to this add-on, bug 12916, or RFC 2822 section 3.6.6.

As a workaround you can also redirect your messages through another email provider, e.g. Gmail, but this isn't always desirable, because then that email provider gains access to the messages you redirect, and those messages might contain sensitive information.
