It took way too long, but my #ChatOps quest continues. Today I finished adding #Matrix support to my #Dovecot Sieve scripts, so that things like #DKIM and MTA-STS TLS reports could go to a matrix chat channel rather than sitting in a mail folder. Basically I now have an email 👉️ matrix bridge.

It took a fair amount of fussing about, mostly because (a) it takes matrix commander (a Matrix CLI) a long time to post a message to Synapse (read: more than ten seconds), (b) Dovecot’s documentation for altering settings for external scripts is byzantine, and (c) rather than cramming matrix commander into my already bloated Dovecot #Docker image I wanted to use the Docker image they provide, and I needed to work out a way to invoke matrix-commander from another container on the same pod.

But now it’s done, and I have another vector for #admin alerts that I can coalesce into a single place for easy review.
