The filter rule applies, for example, if the external program returns zero or nonzero. A similar idea might be to request, that incoming mail is piped through an external filter that can, for example, change the headers. A possible application for the feature would be to integrate a virus scanner into Thunderbird. For example, I could integrate ClamAV or a similar program. Reproducible: Always Steps to Reproduce: 1. 2. 3.
