Topic: Unable to connect Store/Forward through TLS/SSL
Hi,I'm trying to use the Store/Forward Service for my domain and things are working well when I use the basic SMTP Service. However, when I try to get the service to push the email to my mail server using TLS/SSL, it won't get the mails through.I use a certificate from Let's Encrypt on the Synology NAS. And using Synology Mail Server as the backend.In my logs, I can see the following:2024-05-27T17:50:34+02:00 blackhole postfix/smtpd[4417]: connect from mx2.dynu.com[107.161.27.201]2024-05-27T17:50:34+02:00 blackhole postfix/smtpd[4417]: SSL_accept error from mx2.dynu.com[107.161.27.201]: -12024-05-27T17:50:34+02:00 blackhole postfix/smtpd[4417]: warning: TLS library problem: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol:ssl/statem/statem_srvr.c:1685:2024-05-27T17:50:34+02:00 blackhole postfix/smtpd[4417]: lost connection after CONNECT from mx2.dynu.com[107.161.27.201]2024-05-27T17:50:34+02:00 blackhole postfix/smtpd[4417]: disconnect from mx2.dynu.com[107.161.27.201] commands=0/0I would be very grateful if anyone could help me resolve this.

Try reducing the TLS / SSL Profile Level to intermediate if it is set at Modern (Control Panel, Security, Advanced tab).

On your Dynu Email service mangement screen, try different options in the "Connection Security" drop down list.
