Technical assistance
#1

Infos:

  • Used Zammad version: 3.7.x
  • Used Zammad installation source: (source, package, …) Docker
  • Operating system: Debian 9
  • Browser + version: Chrome

Expected behavior:

  • Comfigure outgoing email with secure SMTP server

Actual behavior:

  • Response with error: “SSL_connect returned=1 errno=0 state=error: unsupported protocol”

Steps to reproduce the behavior:

  • When I try to configure an outgoing address to send email, I receive this error. My email server need SSL enabled on port 465.

Two things before we continue:

  • If using docker, please use our docker-compose - the docker image is not production safe
    (mentioned here: Install with Docker — Zammad documentation )
  • Zammad 3.7 currently is develop, this means it may unstable - you may want to switch to stable instead

Please ensure that your Zammad host / node supports the same SSL/TLS protocols and ciphers like your mail server does. Above error usually indicates the mail server not supporting what Zammad does.
