OK, I’ve been living with this for too long, and I can’t find anything about it anywhere with web searches.
Thunderbird’s spam filter is absolutely stupid. Every effing day I have to dig through the junk folder to find legitimate email from people whom I’ve repeatedly (as in dozens of times) told it are not spammers, and from subjects (e.g., mailing lists, like arocket) that I’ve repeatedly told it is legitimate email I want to read. It absolutely refuses to learn. I can handle false negatives in spam reporting, but when it continually buries legitimate emails after I’ve implicitly whitelisted them, I can no longer tolerate this.
Am I the only one with this problem?
