Somebody mentioned above that KMail should be able to delete attachments from signed e-mails. Installing KMail would however pull loads of KDE dependencies which I don't really want, so I just Evolution 3.44.4-0ubuntu2, which comes with Ubuntu MATE 22.04.
If you delete an attached text file, Evolution replaces its contents with this text line: File "filename.txt" has been removed. That is, it does not really completely remove the attachment like Thunderbird does, but it should reduce its size drastically. However, I couldn't remove an attached PDF from a signed e-mail with Evolution. There was no error message, but the removal just didn't work. That is similar to the behaviour of Thunderbird's add-on "Attachment Extractor": it does not remove the attachments of signed e-mails, but it does not complain either. It just fails silently. I am guessing that this add-on is just a convenience wrapper to apply Thunderbird's attachment removal logic to many e-mails at once. I would be grateful if anybody else could mention some other e-mail client, add-on or command-line tool which could delete attached files from signed e-mails. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/303140 Title: No more "Save all" / "detach all" / "delete all" for attachments To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/303140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
