snappymail integration broken with TLS_FLAVOR=notls in master

The problem is that you are mixing master and 2.0; If you want to run master, re-run setup and use the master version of all images, that will fix the problem you are encountering.

nope, that's not it. I tested this with all latest images.

Just to be sure, I just retried it with a fresh config from the setup wizard: https://setup.mailu.io/master/setup/38bd828c-130e-4e91-bd11-867d0ddfd86b
