Two questions.  First one is I guess just a newbie configuration question.  My existing dovecot.conf ends with
!include conf.d/*.conf
!include_try local.conf

I didn’t have a local.conf, so I decided that would be a good place to put this.  I created it with
auth_stats=yes
mail_plugins = $mail_plugins stats
stats_carbon_server = 94.237.81.63
stats_carbon_server = [2a04:3542:1000:910:acc1:5bff:fe5e:8c2]
stats_carbon_name = RedHorseMail
plugin {
  stats_refresh = 30s
}


At startup, I get error (warning?) 

Aug 14 10:50:38 v1 dovecot: config: Warning: /usr/local/etc/dovecot/local.conf line 2: Global setting mail_plugins won't change the setting inside an earlier filter at /usr/local/etc/dovecot/conf.d/15-lda.conf line 48 (if this is intentional, avoid this warning by moving the global setting before /usr/local/etc/dovecot/conf.d/15-lda.conf line 48)

I sort of understand what this is telling me, that my new mail_plugins directive clashes with the previous one in 15-lda.conf, which is
   mail_plugins = $mail_plugins sieve

But aren’t both of these commands concatenations, which effectively add more plugins to the existing $mail_plugins string, so that they’re cumulative and not really conflicting?  Can I just ignore this message?  Is there a way to make it go away?

It appears that, in spite of the warning, the stats code is activating, or attempting to activate, which brings me to my second question.

In my dovecot log, I see
 Error: stats: open(/var/run/dovecot/stats-mail) failed: Permission denied

/var/run/dovecot/stats-mail does not exist, I assume it is trying to create it and being denied by permissions on /var/run/dovecot, which is
drwxr-xr-x  5 root   wheel     1024 Aug 14 10:51 dovecot

Do I need to change ownership of that directory to the dovecot user?
