Hello,
we use the SMS2Mail Function with SMTP Submission.
We successfully configured the TRB140 Mail Client to send the Test emails over our mailserver.
However the Mails from SMS2Mail are not being submitted. In the mailserver log the cypher used is different for test emails and SMS2Mail emails:
Test uses TLSv1.2
SMS2Mail uses TLSv1.3
The Mailserver is not able to handle TLS1.3, is there a way to use TLS1.2 with the SMS2Mail function?
Best Regards 
Hello,
The test mail function uses a different library for sending emails than the app itself. Unfortunately, there is no option to send emails with TLS 1.2.
Let me know if you have any more questions regarding this.
Best regards,
Hi Marija,
thanks for your reply, we also noticed that when looking into the log from the troubleshooting archive.
We also figured out why this was not working, the customer set up the connection to ignore cert-failures and used the mailservers IP address. The sendmail test was OK, but the app failed at the starttls command with SSL: no alternative certificate subject name matches target ipv4 address ‘x.x.x.x’
So we now use hostnames instead and now it works fine
Regards
