Email Recall undo send Modern UI
By: zimbra
Undo Send Zimlet
The undo send Zimlet is a proof of concept not-production ready Zimlet. It allows a user to recall a message that has already been sent. The Zimlet works by running a zmmboxsearch on your Zimbra server and look for messages with the message-id of the message to recall. It will remove the message from all mailboxes and place a notification message telling the users a message has been recalled. The Zimlet can not undo the sending of messages that are already on 3rd party mail servers.
Installing
To perform the installation you can run the auto installation script as root as follows:
wget https://raw.githubusercontent.com/Zimbra/undosend/main/undo-send-installer.sh -O /tmp/undo-send-installer.sh
chmod +x /tmp/undo-send-installer.sh
/tmp/undo-send-installer.sh
Usage from CLI
You can use this Zimlet from the command line as zimbra user:
/usr/local/sbin/undosend 953242361.435.1586347147822.JavaMail.zimbra@mind.zimbra.io
So use value from Message-Id header without . Please note, this command line script does not check permissions, so it will remove the mails with the requested message-id if it finds them.
Java Extension
The java extension for use with the Zimlet does verify the From header against the user's account email address and aliasses.
Limit undo send time
To limit the time in which people can undo send, add after:-$2minutes to the query in undosend script if you wish to pass the undosend time usage a CLI argument or just hardcode it.
