Do you use postfixadmin?
I run a virtual mail environment for a few domains.
I also have roundcube that is occasionally used. (my daughter in 
Manchester UK, and my son in Baltimore)
You have spamassassin, mailgraph and fail2ban that I do not have.

I would be interested in seeing your configuration steps.  I have used:

http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMailServer

As my guide in the past.

What I see on the current CubieTruck RSEL6 setup (running for a couple 
of years now) is that 2 instances of amavis are going, checking out the 
mail, and pretty much pegging the CPUs (as reported by top).  Meanwhile, 
at times when I go to send mail from Thunderbird, it reports it is 
waiting on my mailserver.  I assume that the server is too busy at the 
moment to take the mail.

Right now I am going to write up all I have done for a basic Cubie 
Centos7 setup.

Separately I would like to learn a bit about nextcloudserver.  I run a 
ClearOS6 Samba server here.  I am looking for alternatives, but serving 
MS shares with client login is needed.
