Thank you Christian for clarifying this.
It seems that the obsoleted parameters survived somehow several
migrations since ancient times

And here is the solution:
I had to explicitely tell the smtp proxy to NOT use tls by specifying
-o smtpd_use_tls=no
-o smtp_use_tls=no
-o smtpd_tls_security_level=none
-o smtp_tls_security_level=none
where it seems that simply setting smtpd_use_tls and smtp_use_tls to
no was not enough! The additional smtp_tls_security_level set to
"none" was also necessary
The options smtpd/smtp_use_tls are obsolete and
smtpd/smtp_tls_security_level should be used instead. You can remove
the smtpd/smtp_use_tls option from both main.cf and master.cf and it
should be good
Take a look at the documentation
From http://www.postfix.org/postconf.5.html#smtp_tls_security_level
- smtp_tls_security_level
The default SMTP TLS security level for the Postfix SMTP client; when
a non-empty value is specified, this overrides the obsolete parameters
smtp_use_tls, smtp_enforce_tls, and smtp_tls_enforce_peername.

From http://www.postfix.org/postconf.5.html#smtpd_tls_security_level
- smtpd_tls_security_level
The SMTP TLS security level for the Postfix SMTP server; when a
non-empty value is specified, this overrides the obsolete parameters
smtpd_use_tls and smtpd_enforce_tls. This parameter is ignored with
"smtpd_tls_wrappermode = yes".
