As per request, I am filing here the suggestion previously explained by mail... WHAT: I think it would be a truly helpful addition to add the possibility for the remove attachment plugin to expose a couple of conditions and actions on both the filtering and processing rules. WHY: Typical usage scenarios would include removing images from html mails (in a filter) or remove old, superseded versions of a documents being discussed on a ML, keeping the comments in the mail body (in a processing rule). Less typical but still relevant scenario (this is my case right now) to remove attachments from over 35.000 individual mails on migration to claws-mail from another platform that would not allow attach removal. HOW: Ideally, conditions should expose at least file types / file extensions [power users might appreciate the possibility of using a regex, though], while I would be happy to have a "delete" option only in the actions [a plus could be to have a "save to folder" option as well, though]. I think exposing the file types / file extensions is essential because some mail client forwards messages as attachment, and typically these are not to be removed. Regards and congratulation for the awesome piece of software! :)
