Simple Mail Redirection

Thunderbird 91/102/115

Hinweise:

Dieses AddOn implementiert das Umleiten gemäß RFC5322, Abschnitt 3.6.6. Die in Thunderbird 91 eingeführte Funktion 'Umleiten' funktioniert völlig anders und ist eher ein Weiterleiten ohne die Originalmail als Zitat zu markieren.


Hints:

This AddOn implements redirect as defined in RFC5322, Section 3.6.6. Thunderbird 91 introduces a new 'Redirect' which works quite differently. It's more a 'Forward' but without quoting the original mail.

Context menus Popup window with selected mails and input fields for recipients

Beschreibung

Erlaubt es, Mails umzuleiten.

Bei einer Umleitung sieht es für den Empfänger aus, als ob die Mail direkt an ihn verschickt worden wäre. Antwortet er auf so eine Mail, bekommt der ursprüngliche Absender die Antwort.

Nutzt die Erweiterung 'cardbook' wenn sie installiert ist

Basiert auf dem Add-on 'Mail Redirect' von Onno Ekker and Pawel Krzesniak

Version 1.11 erlaubt die Auswahl von Maillisten. Außerdem kann das Fenster 'gezoomt' werden (Strg/+, Strg/-, Strg/0)

Umgeleitete Mails bekommen das Schlagwort 'redirected'.

Description

Allows to redirect mails.

When a mail is redirected, it looks to the recipient as if the mail was directly sent to him. If he replies to such an email, the original sender receives the reply.

Uses the add-on 'cardbook' if installed

Bases on the add-on 'Mail Redirect' from Onno Ekker and Pawel Krzesniak

Version 1.11 allows to select maillists. It is also possible to zoom the window (CTRL/+, CTRL/-, CTRL/0)

Redirected mails get the tag 'redirected'.

Warum funktioniert es nicht?

Dieses Add-on funktioniert nicht mit allen Mailprovidern (z.B. office365.com, outlook.com, web.de, gmx.de). Die Fehlermeldung des Providers lautet dann etwa "Unauthorized sender address", "SendAsDenied; ... not allowed to send as ..." oder "Sender mismatch". Der Grund ist, das Mailprovider Sicherheitsmaßnahmen einsetzen, die u. U. mit dem Standard (RFC 5322), auf dem dieses Add-on basiert, kollidieren.

Ein weiteres Problem gibt es mit t-online, googlemail und möglicherweise weiteren Providern. Die Umleitung funktioniert aber die Von: Adresse wird auf den Absender der Umleitung umgeschrieben.

Als Workaround kann man sich eine Mailadresse bei einem Provider besorgen, der diese Probleme noch nicht hat (leider kenne ich keinen) und diesen zum Umleiten verwenden. Ggf. einen eigenen Mailserver für diesen Zweck einrichten. Dann das Konto im Popupfenster ganz oben umschalten.

Why doesn't it work?

This add-on does not work with all mail providers (e.g. office365.com, outlook.com, web.de, gmx.de). The provider's error message is then something like "Unauthorized sender address", "SendAsDenied; ... not allowed to send as ..." or "Sender mismatch". The reason is that mail providers use security measures that may conflict with the standard (RFC 5322) on which this add-on is based.

There is another problem with t-online, googlemail and possibly other providers. The redirection works but the From: address is rewritten to the sender of the redirection.

As a workaround, you can get an email address from a provider that doesn't have these problems yet (unfortunately I don't know of any) and use that to redirect. If necessary, set up your own mail server for this purpose. Then switch the account in the pop-up window at the top.

Nutzung

Rechtsklick auf eine Mail oder Auswahl mehrerer Mails und dann Rechtsklick auf eine davon. Im Kontextmenu auf 'Umleiten' (ganz unten(!)) klicken.

Im Popupfenster werden oben die ausgewählten Mails angezeigt. Versehentlich ausgewählte Mails können durch Klicken auf den Papierkorb entfernt werden.

Im unteren Teil können die Empfänger eingegeben werden. Entweder einfach losschreiben und ggf. aus dem dann erscheinenden Menu eine Adresse auswählen
oder durch klick auf das Icon rechts das Adressbuch öffnen und Adressen aus dem Adressbuch in die Eingabefelder ziehen.

Klick auf 'Senden' startet den Vorgang. Zum Abbrechen eben auf 'Abbrechen' klicken oder das Fenster schließen (dann gibt es aber keine visuelle Kontrolle!). Einzelne Mails können auch durch klick auf das 'x' vor der Mail abgebrochen werden.

Damit umgeleitete Mails mit entsprechenden Icons markiert werden, in den Einstellungen von Thunderbird ein Schlagwort 'redirected' einrichten.

Usage

Right click on a mail or select several mails and then right click on one of them. Click on 'Redirect' (far down(!)) in the context menu.

The selected mails are displayed in the upper part of the pop-up window. Accidentally selected emails can be removed by clicking on the trash.

The recipients can be entered in the lower part. Either just start typing and select an address from the pulldownmenu if it appears
or open the address book by clicking on the icon on the right side and drag addresses from the addressbook into the input fields.

Clicking on 'Send' starts the process. To cancel, just click on 'Cancel' or close the window (but then there is no visual control!). Individual mails can also be canceled by clicking on the 'x' in front of the mail.

To ensure that redirected emails are marked with appropriate icons, set up a keyword 'redirected' in the Thunderbird settings.

Info

Die Redirect-Funktion kann auch in Filtern genutzt werden.
