E-Mail Fetch / Send Problem

Infos:

  • Used Zammad version: 6.5.0
  • Used Zammad installation type: Docker Compose
  • Operating system: Ubuntu 24.04
  • Browser + version: Chrome, 135.0.7049.115

Expected behavior:

  • E-Mail Fetch and Ticket creation
  • E-Mail Send only once

Actual behavior:

  • E-Mails don’t get fetched, the Graph Integration to MS365 connects successfully and can read the shared mailbox and finds E-Mails to fetch. In the Monitoring Tab of Zammad it shows the message emails that could not be processed. When trying to check with several rail commands, I don’t get any hint on what is wrong with the installation. Also, the production.log don’t contain any new data, the entries stopped 3 weeks ago.

  • E-Mails get send, yes, but 4 times in a row, and a error message: Failed to run background job #1 ‘TicketArticleCommunicateEmailJob’. Again, no further hints on what is the problem in detail. I installed the ingest-plugin for ES (as found on another Community Post) but didn’t solve the issue.

Steps to reproduce the behavior:

  • Docker-Compose (Swarm, 3 Nodes) installation with portainer as described here: Install with Docker — Zammad System Documentation documentation
  • modified docker-compose Stack with persistent Storage shares on a glusterFS Volume connected to the 3 nodes, for each Volume that is listed in the docker-compose
  • MS365 Graph Integration configuration, Shared Mailbox, and User that connects to the shared mailbox applied with a EO1 License.
  • Sending/Fetching Email does not work
