Hi there,
New user to MIAB, and gotta say after trying many solutions, it’s far better than all the alternatives.
I have been tinkering ( as I’m prone to do ), and wanted to install the latest Roundcube beta 1.4rc1 release to have the new ‘Elastic’ theme. I also wanted to use this plugin: https://github.com/texxasrulez/Caldav_Calendar which has been authored to use mysql, not sqlite.
The plugin allows to use the built in Calendar template for Roundcube’s ‘Larry’ theme ( with Elastic hopefully soon ), and connect to the NextCloud calendar directly from within Roundcube’s interface.
To install it I basically deleted the entire /usr/local/lib/roundcubemail directory, installed php-mysql + mysql-server, created the roundcube user and empty DB and then unpacked the roundcube 1.4rc1 tar package into the /usr/local/lib/roundcubemail dir and run the web based installer as if it was a vanilla install. It all works perfectly!
However, just wanting to know the implications and possible impact doing this might have. It all seemed a little…too easy! 
- Backups - given the DB is stored in /var/lib/mysql will it be picked up by the backup script?
- Is the default sqlite database used directly by any other parts of MIAB, which now means there is a separation of data sources with roundcube using mysql, and other parts using the original sqlite DB? If so, is that actually a problem?
Any thing else I’ve possibly stuffed up?
Having said that, it all works fine and suits my personal needs in this configuraiton, but just wanting to make sure i haven’t mucked something up badly that isn’t obvious but might bite me down the track.
@JoshData Thank you so much for this project! It’s a work of art!
