Thunderbird Extension Custom Sender Address and Reply
The Thunderbird extension Custom Sender Address and Reply
(Cusedar for short) is a merge of
Reply as Original Recipient
with new features added.
Cusedar allows the user to define custom “From”-addresses based
on the recipient mail address. Either by defining rules in the extension
options, or in the address book.
In addition, when replying to a mail the extension can check the “To”-address of the received mail and with a regular expression match this address is used as the new “From”-address. Thus ensuring you always reply with the correct identiy.
- Custom “From”-address based on rules
- Custom “From”-address based on address book lookup (“Custom 3” entry)
Supported Formats: “firstname.lastname@example.org”, “sendername <email@example.com>”
- For replies use “To”-address as “From”-address, based on regular expression match
There are various installation methods available, depending on your needs
They are sorted in the following by their likelyhood, i.e. when you’re unsure select the first one you feel comfortable with.
Please be aware that Cusedar and Flexible Identity will compete about the
same controls, because they are akin.
So expect trouble when you have both extensions installed, which is strongly discouraged.
Install from Thunderbird Add-On Site
Find it here:
Download prepared package
Head over to the release page:
And fetch the provided xpi.bin file.
After you renamed it to .xpi (otherwise Firefox blocks the download) you can install it manually in Thunderbird (Add-On Manager, Install Add-On from file).
Create own package
- Download or clone this extension
- Change into the directory
- (Optional when you made local changes)
git clean -i -x
- zip -r -9 ../cusedar-VERSIONNUMBER-tb.xpi . --exclude .git/\*
For a local installation create a file named
with it’s only content being the path where you downloaded or cloned this extension.
This is the perfect starting point for your own modifications.
Update from Flexible Identity
- Close Thunderbird, when it’s currently running
- Open file prefs.js in your Thunderbird profile (make a backup),
replace text “extensions.fid.” with “extensions.cusedar.”
- Rename file “flexible-dentity.json” to “extension-cusedar.json” in your Thunderbird profile
- Start Thunderbird
- Uninstall Flexible Identity
