I need more info on DB caching

[tjos]

I want to fetch emails from roundcube and save it to another database table.
Its basically an audit table where I log certain conversations that are relevant to a business' task.
(Attachments will also need to be saved to a file-system, but there are plugins for that and that is not my immediate concern.)

To my understanding, roundcube only caches email headers in the db. I was hoping to fetch the data from one table and insert it to another table.

I need advice as to how I should approach this issue. I would appreciate any resources that you can provide about how db caching works in roundcube.

Using roundcube version 1.0

You should do this at the mail server layer not in Roundcube.
