I have Thunderbird up and running on one of my Oracle Linux Virtual Machines. I enabled the FiltaQuilla extension, because I want to save message attachments automatically to a local filesystem, and then run a backend script against those saved attachments. Everything appears to be configured correctly. The email filter is working sporadically. Sometimes it works, and sometimes it doesn't. It is not consistent. It does not seem to work immediately, and it does not seem to work when I try to manually run it. But, if I leave my computer for a little while and come back, the saved files will magically appear, "somehow", but only sporadically. Even though the filters appear to be enabled, they are not being kicked off when the new messages arrive. I currently have 3 options in place, in the "Filter Rules" window: "Manually Run", "Getting New Mail: Filter before Junk Classification" and "Periodically, every 10 minutes". I wish there was an option to "Run with each new message received". I set a "Subject Contains" filter, and that is my only filter. Then I tried both "Detach Attachments To" and "Save Attachments To", but neither of them seems to be working properly. For a brief few minutes, I attempted to combine "Move message to folder", but it moves the message immediately, before the first filter has a chance to save it to the local filesystem. When you have different actions in mind, there MUST be a way to prioritize each action, so that the first option MUST complete successfully, before attempting to complete the second, and subsequent actions. In my case, I need to save the attachments to the local machine, before removing or moving the message. So, if action number one completes successfully, it goes on to complete the second action. If action number one fails, it stops all processing of future steps, so that the failure can be debugged. I really need a solution to the saving of attachments to local filesystems (This is in Linux).
