In case anyone else happens to experience the same issue, here's a couple of simple steps to roll back to the previous version: (assuming you are on nextcloud docker)

1. disable the app from nextcloud apps menu or occ app:disable snappymail
2. docker exec -it -u www-data <your nextcloud instance> bash
3. cd /var/www/html/custom_apps/
4. rm -fr snappymail
5. curl https://snappymail.eu/repository/nextcloud/snappymail-2.27.3-nextcloud.tar.gz | tar -xzvf -
6. enable snappymail again occ app:enable snappymail

I had to comment out this one and a few others to be able to activate the app again : SIGCLD, SIGPOLL, SIGPWR, SIGSTKFLT

I'm running 26.0.1, PHP 8.0.28, PostgreSQL 13.11

Is there going to be a release with commit? or do I have to manually edit the file so my users can access their emails through Nextcloud.

Thanks.
