There had been another filter, but roughly 25% of junk mail was properly being flagged and routed to the Junk folder so I doubt that was the case.
Another thing is you might have conflicting entries in the Allowed Senders or Allowed Receivers word list.
One thing I find useful it to the select problematic message(s) and use Apply and Test. The resulting pop up gives you the total junk score (XPS) and also the details that resulted in getting that score.
For example some spams put your address in the From: header, if you add your self to your address book, that message will get a -20 score to figure in with the total score.
Interesting. I never used the Apply and Test function before but will utilize it in the future for especially persistent spam. I tried it on one piece of spam that keeps getting through no matter how many times I classify it as junk in PocoMail. Here are the results:

I don't understand the language. Can you interpret this for me?
BTW, the "SPAM" designation in the subject field was put there by Fastmail on the server side. They do their own filtering but I have the controls on the server side set to just medium. If I set it higher, too much of my non-spam mail gets caught in their spam filter.
I do know for a fact that some of the mail I have been having problems with did not have my email address in the "From" field. When you choose an action, a little window pops up to tell you what's been banned. That's how I know that some email addresses supposedly banned by PocoMail were continuing to get through.
As I look at my spam collection, I see as varied number of spam names as I do spam addresses. Selecting Ban Sender essentially accomplishes the same thing. I see very little gain in adding the name too.
I have been getting many emails lately that have the exact same name but with different email addresses for each one. For example, I'll get 8 emails a day from "Slim Shake" or "Winter BooK" or "New Car" but there will be a different email address for each one. When this happens, the built in junk filters are worthless since none of them will automatically ban the name. And it's simply not feasible for anyone to have to manually type in these names in a text document every day. If PocoMail's junk filter when applied would simply automatically ban the name, that might improve it's success rate greatly. Why it won't do that is beyond me.
If that is what you want then the only what to add them is manually. Sorry about that. You could also use Ban Sender's Domain, that would take care of the domain, those those are also many variations.
I have been using Ban Sender's Domain quite often. But as I explained in my original post, it did almost nothing as the spammers are changing the originating e-mail address with almost every piece of mail. And, as I subsequently mentioned, even when I did ban a specific email address, it would still mysteriously get through afterwards.
I just retrained my Bayesian filters using 882 junk messages and 199 good messages. I then applied the Junk Mail filters to the messages. Out of 882 messages 22 were not filtered to Junk Mail.
If I can get Pocomail's filter to start working better I'll be happy. That's why I'm here now. It seems there is a new version of PocoMail in the works and now in beta testing? I do hope the developers are addressing the issue of junk mail filtering.
The good news is that Cactus Spam Filter is actually doing a pretty good job of filtering spam for me in the very short time I've been using it (just two days). Within 24 hours it was doing what PocoMail has been failing to do over weeks and even months. Cactus within 24 hours was catching over 90% of the spam. The problem is sometimes I have to turn it off as certain pieces of mail gets "stuck" while processing and PocoMail times out. I then have to shutdown Cactus and then PocoMail will finish processing new mail on the server normally.
The ideal of course is to get PocoMail's filtering to work better.
