Ok. I think initial SMTP TLS report support is done, including JSON, CSV, Elasticsearch, and Splunk output, but I haven't done much testing yet

Other steps that are needed:

• Add SMTP TLS report output support to the Kafka client. @mikesiegel, can you look into this?
• Add SMTP TLS report output support to the LogAnalytics client. @rubeste, can you help with this?
• Add SMTP TLS report output support to the S3 client. @tom-henderson, can you help with that?
• Add SMTP TLS report output support to the Syslog client. @chris-y, can you help with this?
• Add SMTP TLS report dashboards for Splunk. I should be able help with that once I get more failure examples.
• Add SMTP TLS report to the Kibana dashboard. I haven't had ELK set up for a while, so if someone else could contribute dashboard changes would be awesome.
• Add SMTP TLS report support to the Grafana dashboard.
• Add SMTP TLS report samples and tests

I was able to reuse existing code to create SMTP TLS report output support for Kafka, S3, Log Analytics, and Syslog. I have not tested any of these and testing would be appreciated.

[rubeste]

@seanthegeek I'll see if I can test it for Log Analytics. But I first need an SMTP TLS report.

Hi @seanthegeek

I haven't worked in a Kafka environment/dealing with DMARC since 2020. I can reach out to some old coworkers though and see if they can help out.

[tom-henderson]

Hi @seanthegeek it's been a while since I've looked at this but the changes in s3.py look good to me 👍

[chris-y]

As far as I can tell the syslog looks ok, I'm not able to test though.

@seanthegeek Created a Pull request #459 with some fixes and documentation.

I have also tested the application and it works now.
