Mailrise on the public domain (:465)

[info-path]

I can't get mailrise to work on a public domain. I would like to use it as my smtp server from anywhere.

My intention:

[user:465] --> [router:465] --> [traefik route :465 to :8025] --> [mailrise:8025]

But I can't establish a connection at all.

send-mailmessage -from "admin@homelab.local" -to "telegram@mailrise.xyz" -subject "Windows Test" -body "Test message" -smtpserver mailrise.mydomain.com -port 465
or
send-mailmessage -from "admin@homelab.local" -to "telegram@mailrise.xyz" -subject "Windows Test" -body "Test message" -smtpserver mailrise.mydomain.com -port 465 -UseSsl

Return error: net_io_connectionclosed

Traefik (exposed ports: 80, 443, 465):

      rule: "HostSNI(`mailrise.mydomain.com`)"
      tls:

      service: mailrise-service

  mailrise-service:
    loadBalancer:

mailrise.conf:

  mode: off

I have defined the certificate according to this guide: https://technotim.live/posts/traefik-3-docker-certificates/

Has anyone solved this?

So the bug is in PoweShell (send-mailmessage), which does not support sending smtp on port 465. On another application everything works!
