for several days now, I have been receiving a new type of spam email

emails consists of automatic replies (notification of absence,
vacation, processing). Therefore, I cannot add them to Bayes training.
Why?
As I understand it, autoresponders, newsletters, and system
notifications should not be added to the Bayes database. If you write to
the company and receive their automatic legitimate response, it could be
mistakenly classified as spam then? Only emails whose content is
typically spam-like (e.g., advertising, phishing, dubious wording,
tracking pixels, etc.) are suitable for Bayes.
I have already lowered the score for the MAILING_LIST_MULTI check.
Lowered? Because of this?
The bonus MAILING_LIST_MULTI=-1 is too much for me :)
However, the emails are not detected by Spamassassin's standard
blocklists. I don't know how to detect these emails. Which blacklists
(https://www.intra2net.com/en/support/antispam/) should I definitely
add to local.cf in addition to the standard blocklists?
Can you provide samples? (use web, pastebin or similar service)
I imagine that spammers are also reading this list in order to optimize
their spam generators. I'm not sure if that's such a good idea. The spam
messages mentioned were only generated for German-speaking countries
because only the automatic replies from German companies appear with the
original addresses, among other things. This type of spam is absolute
chaos :-)
