Dovecot quota and Postfix smtpd_recipient_restrictions?

[Davide Marchi]

Hi Friends,

a doubt:

I would like to enable (the same) quota (count) for all (virtual)users,
on Debian Stretch, Postfix 3.1.8, Dovecot 2.2.27,
and is not clear for me if I need to tell Postfix to communicate with 
the service in /etc/postfix/main.cf as here:


smtpd_recipient_restrictions =
     ...
     check_policy_service inet:mailstore.example.com:12340



My current Postfix "smtpd_recipient_restrictions":


-o 
smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject



Currently I've edited:



conf.d/10-mail.conf:

# Space separated list of plugins to load for all services. Plugins 
specific to
# IMAP, LDA, etc. are added to this list in their own .conf files.
mail_plugins = $mail_plugins quota


conf.d/20-imap.conf:

protocol imap {
   # Space separated list of plugins to load (default is global 
mail_plugins).
   mail_plugins = $mail_plugins imap_quota
}


conf.d/90-quota.conf: (for use with the quota-status service)

plugin {
     quota_grace = 10%%
     # 10% is the default
     quota_status_success = DUNNO
     quota_status_nouser = DUNNO
     quota_status_overquota = "552 5.2.2 Mailbox is full"
}



/etc/dovecot/conf.d/90-quota.conf:

plugin {
quota = maildir
quota_rule = *:storage=3G
quota_rule2 = Trash:storage=+100M
   # LDA/LMTP allows saving the last mail to bring user from under quota 
to
   # over quota, if the quota doesn't grow too high. Default is to allow 
as
   # long as quota will stay under 10% above the limit. Also allowed e.g. 
10M.
   #quota_grace = 10%%
   # 10% is the default
   quota_status_success = DUNNO
   quota_status_nouser = DUNNO
   quota_status_overquota = "552 5.2.2 Mailbox is full"
}
plugin {
   quota_warning = storage=95%% quota-warning 95 %u
   quota_warning2 = storage=80%% quota-warning 80 %u
}
plugin {
   #quota = dirsize:User quota
   #quota = maildir:User quota
   #quota = dict:User quota::proxy::quota
   #quota = fs:User quota
quota = count:User quota
   # This is required - it uses "virtual sizes" rather than "physical 
sizes" for quota counting:
   quota_vsizes = yes
}
plugin {
   #quota = dict:user::proxy::quota
   #quota2 = dict:domain:%d:proxy::quota_domain
   #quota_rule = *:storage=102400
   #quota2_rule = *:storage=1048576
}
service quota-warning {
   executable = script /usr/local/bin/quota-warning.sh
   user = dovecot
   unix_listener quota-warning {
     user = vmail
   }
}
service quota-status {
     executable = quota-status -p postfix
     inet_listener {
         port = 12340
         # You can choose any port you want
     }
     client_limit = 1
}



Many many thanks!!
