Hello,
after an upgrade of postfix I am checking my config.

I am in the impression, this should work:
# openssl s_client -connect mail.swabian.net:465 -starttls smtp -tls1_3
CONNECTED(00000003)
Didn't find STARTTLS in server response, trying anyway...
write:errno=32
---
no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 0 bytes and written 33 bytes
Verification: OK
---
New, (NONE), Cipher is (NONE)
This TLS version forbids renegotiation.
Compression: NONE
Expansion: NONE
No ALPN negotiated
Early data was not sent
Verify return code: 0 (ok)
---

but as you see, it doesn't - on port 25 it is working fine.

in master.cf:
smtps    inet  n       -       n       -       10       smtpd
  -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes
  -o smtpd_tls_security_level=encrypt

i think those are relevant from main.cf:
smtpd_tls_security_level =
smtpd_tls_wrappermode = no
smtpd_use_tls = no

what did I miss?

thank you
