Following this guide: http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ I can't seem to get it to work, as soon as I add the smtpd_recipient_restrictions setting to postfix I can no longer send mail at all. I get the message SMTP Error (450): Failed to add recipient "postmaster@example.com" (4.7.1 : Recipient address rejected: Internal error occurred. Refer to server log for more information.). I googled around and found this command to test the quota-status service: printf "recipient=postmaster at example.com\nsize=1234\n\n" | nc 127.0.0.1 12340 It seems to always return the quota_status_nouser message. I'm really stumped here. What logs do I need to check for errors and does anyone have any experience with this?
I'm not an expert, I just followed the same guide a few days ago while preparing to front an old vpopmail system with postfix. It did work for me.
Before moving on to enabling the check in postfix, verify that the dovecot side is working.
Your example test should work, I did the same here:
[root@util-b /usr/local/etc/postfix]# printf "recipient=chip@test.bway.net\nsize=12304\n\n" | nc mbox.i 25001 action=DUNNO
[root@util-b /usr/local/etc/postfix]# printf "recipient=chip@test.bway.net\nsize=123000000004\n\n" | nc mbox.i 25001 action=552 5.2.2 Mailbox is full
If that fails for you, examine the dovecot log. In my case, I did have to provide the full path to the "quota-status" binary and dovecot complained about not being able to find it. Make sure you actually have quota-status installed. Full dovecot snippet for this below:
# report quota to postfix # see http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/
plugin { quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" }
service quota-status { executable = /usr/local/libexec/dovecot/quota-status -p postfix inet_listener { address = 10.x.x.19 # In my case I want it listening on a particular IP port = 25001 } client_limit = 5 }
If the dovecot portion is working, then move on to your postfix logs…
