I keep hitting TLS errors:
Jul 15 15:58:48 htznr2 maddy[923]: remote: cannot use MX {"domain":"lists.denog.de","msg_id":"e693452d-66952b17","reason":"TLS it not available or unauthenticated but required","remote_server":"mail1.cluenet.de.","required_tls_level":"encrypted","smtp_code":451,"smtp_enchcode":"4.7.1","smtp_msg":"TLS it not available or unauthenticated but required","tls_err":"tls: server selected unsupported protocol version 301","tls_level":"none"}

Log says "required_tls_level":"encrypted" despite all my attempts at configuring maddy to ignore it, including min_tls_level and min_mx_level.
Is this a bug or am I doing something wrong in the configuration file?
Steps to reproduce
Send email through maddy To:
please-ignore@lists.denog.de (TLSv1.0, self signed cert)
please-ignore@1wt.eu (no TLS support)

Configuration file
## Maddy Mail Server - default configuration file (2022-06-18)
# Suitable for small-scale deployments. Uses its own format for local users DB,
# should be managed via maddy subcommands.
#
# See tutorials at https://maddy.email for guidance on typical
# configuration changes.

# Base variables
$(hostname) = server2.example.eu

# Local storage & authentication
# pass_table provides local hashed passwords storage for authentication of
# users. It can be configured to use any "table" module, in default
# configuration a table in SQLite DB is used.
# Table can be replaced to use e.g. a file for passwords. Or pass_table module
# can be replaced altogether to use some external source of credentials (e.g.
# PAM, /etc/shadow file).
#
# If table module supports it (sql_table does) - credentials can be managed
# using 'maddy creds' command.

# imapsql module stores all indexes and metadata necessary for IMAP using a
