Mailcow-dockerized: docker-compose issue regarding MAILDIR_SUB

[CFuchs174]

I tried to setup a new server for testing purposes using docker-compose as explained in the documentation with the newest version. I saw in the GIT history that parameter "MAILDIR_SUB" was added recently. However, it seems to cause problems when setting up a new server:

ERROR: Invalid interpolation format for "environment" option in service "dovecot-mailcow": "MAILDIR_SUB=${MAILDIR_SUB:-}

Any ideas on how to solve the issue? Thanks!

Cannot replicate with latest compose. We cannot help if you guys skip the issue template, sorry.

I have tried the setup on a fresh installation of the server and it worked... Seems to have been an issue with the old machine (despite of the latest docker-compose). Sorry for the inconvenience.

for those who find this issue when they search for this problem.
it can also happen when you run docker-compose without sudo rights!

you're using an old version of docker-compose. the new syntax was added in version 1.19.0 and older versions can't understand it.
