Spam not learned when moving to spam folder

Help with Unusual Circumstances
1

I have MaiB for several years. Now everything is upgraded to the latest versions.

I noticed in the past months that learning was not ok. When I checked the
sudo sa-learn --dump magic
I could not find any change when I moved an email to the spam folder…

Any idea on what may be wrong? Or what and how should I check the filters?

I really like MIAB, but Spam Handling is an absolute Pain.
I´ve ended up creating my own filter with a Sieve file.

In the Folder /etc/dovecot I´ve created the file “sieve-spam.sieve” with this code - works like a charm.

require ["regex", "fileinto", "imap4flags", "reject", "body", "mailbox"];


if address :domain  :matches "from" ["*fisteraser.de", "*freenet-mobilfunk.de", "*.br", "*.tr", "*.xyz", "*.jp", "*.ro", "*.click", "*.pl", "*.cn", "*.tk", "*.buzz", "*.top", "*.ga", "*.cf", "*.gq", "*.icu", "*.wang", "*.host", "*.ir", "*.mg", "*.au", "*.ca", "*.ltd", "*.pro", "*.ru", "*.mx", "*.id"]
    {
        reject "REJECTED";
	    stop;

    }

if header :contains "from" ["huusk", "tfbank", "servicekarte", "doktor", "freenet", "fisteraser", "comdirect", "lidl", "wholesale", "emura"]
    {
        reject "REJECTED";
	    stop;

    }

if header :contains "subject" ["info ", "spende", "invest", "info,", "$user_name$", "keto", "wachstum", "geld", "bersetz", " KI ", "prosta", "reich", "schuppe", "schlank", "dividend", "messer der welt", "apotheke", "sex"]
    {
        reject "REJECTED";
	    stop;

    }
