In 10-mail, mail_plugins is a global variable.  All you are doing here 
is setting it.  Or that is my reading.  Of course this variable is then 
used in the protocols.

Yes.   null unless you set it, as you did in 10-mail.  BTW, I set it in 
local.conf instead of modifying 10-mail.conf.

in 20-imap.conf, it is a protocol:

So you have enabled quota for protocol imap only.  You have already 
defined the global variable mail_plugins so adding it here does nothing 
more.  Do you have pop3 users?  If so you need to modify 20-pop3.conf as 
well.  And I think you need to add it to 15-lda.conf.

And what about imap_quota, do you need that plugin?

I use a mysql query.
