After some relentless searching I found a great plugin that supports multiple IMAP accounts for Roundcube tucked away on BitBucket. It’s a great tool that simply adds a drop down of the IMAP accounts you’ve set-up to the top right area of Roundcube, replacing your email address in that area.
I decided to create the perfect VestaCP server installer script (in my opinion) for CentOS 7 (I have only tried it on CentOS 7). Basically, you run it, it asks a few questions and then it sets up a perfect server including CSF, Monit and PHP 7 (if you want it). Amazing, right?
