I am back after almost 3 years of no server of my own, now I have one again.
I do want to say that I missed i-MSCP and how awesome and easy it is to setup and get running. Frees up more time to work on my own OSS projects. Great Job on the continued development.
I have one minor little issue/request. I do not remember from a while back and maybe I missed something, and I did do a search but couldn't find anything in forum pertaining to this, so I apologize if this is duplicated ... 
I use sauserprefs (1.18.1) with Roundcube (1.4.3) and have it configured to use the database i-MSCP creates for spamassassin upon plugin install and every time I run a reconfig or update, the database password changes. It is easy as pie to find the password (/etc/spamassassin/00_imscp.cf) and change the RC Plugin password accordingly but it would be nice to be able to specify that password and let it be persistent within the plugin install so I don't have to remember to change sauserprefs password too. I am getting older and have CRS disorder and I know this old man would appreciate it. Just my humble opinion.
As I always like to add, Thank you very much for your hard work and keep up the great work ...
