TLS 1.3 is not used

Support General Configuration

I have only TLS 1.2 and TLS 1.3 enabled on WebMail and SMTP Receiving.
WebAdmin > Services > SMTP Receiving (WebMail) > Listener > Edit > SSL Settings >…
I use the ciphers “!AECDH:!ADH:!aNULL:!eNULL:! RC4:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA256:AES128-GCM-SHA256:HIGH:!MD5:!EDH:!EXPORT”

When I check the TLS 1.3 usage at https://www.ssllabs.com/ssltest I see that TLS 1.3 is used
When I check at SMTP TLS Checker For Inbound Email Servers | LuxSci or //email/testTo:
I only use TLS 1.2.
TLS 1.3 is not used.
I use Axigen 10.5.15

What am I doing wrong?

Configuration TLS was wrong.

echo ‘quit’ | openssl s_client -connect IP_ADDRESS:25 -starttls smtp -crlf 2>/dev/null | grep ‘Protocol|Cipher’
