I installed 2.3.4 and just used it with the config files for 2.3.3 without changing anything in the configuration.
I then realized that the LDA was throwing errors.

I checked on the presence of the sockets in /var/run/dovecot:

srw-------   1 root      wheel        0 Nov 24 09:07 stats-reader
srw-rw----   1 root      dovecot      0 Nov 24 09:07 stats-writer

What user/group does dovecot_virtual_delivery run as?

It runs as the MTA user - mailnull.
 
Change the stats-writer socket's owner to be that user. For example:

service stats {
  unix_listener stats-writer {
      user = vmail
  }
}

 
That makes sense.

 
Or alternatively change dovecot_virtual_delivery to use dovecot group.

That would not be possible because it will not have permissions to write the mail files.
 
I have tried to find any mention of stats-{writer|reader} in the example configs shipped with 2.3.4 and found nothing. I have backed-off 2.3.4 for now till I can figure out how to assign proper permissions to these sockets - or just to figure out why by default, permission is being denied.

Looks like this is happening now because in earlier versions the dovecot-lda process wasn't sending any statistics.



BTW, was it an oversight that this config snippet is not documented with the example-config files? Or on the Wiki? Or my eyes are failing me? :-)

 Thank you very much.
