And Postfix logging:

As answered in off-list email, this is an error message from the
Postfix Dovecot SASL client.

You need to turn on one extra level of logging to see which AUTH
mechanism names Dovecot and Postfix expect, and which AUTH mechanism
name the remote SMTP client sends.

main.cf:
    debug_peer_list = 143.198.0.0/16
    debug_peer_level = 1

IMPORTANT: If you include this logging in follow-up email, be sure
to censor the base64 text in the AUTH command because that may
contain a password.

My example was based on the logging your earlier message. You'
need to add something like 2603:1056:c03:1c16:/64":

 main.cf:
     debug_peer_list = 143.198.0.0/16, 2603:1056:c03:1c16::/64
     debug_peer_level = 1

Alternatively you could temporarily increase the logging level for
all submission clients in master.cf with:

 master.cf:
     submission ..... smtpd
        # Execute "postfix reload" after changing master.cf.
        -o debug_peer_list=static:all
        -o debug_peer_level=1
        ...other -o overrides...

But that would log everyone's password.

Sorry for that, I try to active the debbug, but I type the IPV6 and 
forget the []. Now I did the same correctly,

I guess these the most important part of the LOG:
