Hi Guys,

I would like to question why I see this errors in my logs.

Let explain me!

Dovecot version: 2.2.9 (on Ubuntu 14.04 LTS)

I’ve configured our dovecot servers (2 servers) to do the TCP replication with dsync.

This is working flawless.

1. Question:

In logs I can see this errors on every sync (on the “slave” server / server without changes which should be updated):

---8<-----------------------------------------------------------------------

---

dsync-server(email@example.com): Error: net_connect_unix(/var/run/dovecot/replicator-doveadm) failed: Permission denied

---8<-----------------------------------------------------------------------

---

Googling a bit gave me the information “This should be normal”..?

Well ok, errors in logs are not nice to see, but can someone confirm this is really ok? Timo?

2. Question (much more important):

We are using sieve scripts for our users, they are replicated to the replica-host but this errors appears in logs on every synchronized message:

---8<-----------------------------------------------------------------------

---

dsync-server(email@example.com): Error: Failed to access mailbox dovecot/sieve: Internal error occurred. Refer to server log for more information.

dsync-server(email@example.com): Error: stat(/var/vmail/example.com/email/.dovecot.sieve/tmp) failed: Not a directory

---8<-----------------------------------------------------------------------

---

So what’s going on there?

This is strange and should not be, right?

Any hints?

Thank you very much!

2.2.9 is not recent, before debug you might upgrade

Well, not so easy.. we are working on a productive server; this version ships as default for this distro.. I don't even know how to compile my own dovecot version..

see http://hg.dovecot.org/dovecot-2.2/log?rev=replicator

also you missed to attach your dove conf

Relevant config parts: --- /etc/dovecot/conf.d/10-mail.conf --- ---8<----------------------------------------------------------------------- mail_plugins = $mail_plugins notify replication ---8<-----------------------------------------------------------------------

--- /etc/dovecot/conf.d/99-replication.conf --- ---8<----------------------------------------------------------------------- service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0666 } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service doveadm { inet_listener { port = 999 } } doveadm_password = secret replication_max_conns = 1 plugin { mail_replica = tcp:server2.example.com:999 } ---8<-----------------------------------------------------------------------

Thank you for any hint!

Best Regards MfG Robert Schetterer

How does this affect the other packages and the dependencies ? For example, my test system is an Ubuntu 14.04/trusty box ...

$ dpkg -l dove* | fgrep ii ii dovecot-antispam 2.0+20130822-2build1 Dovecot plugins for training spam filters ii dovecot-core 1:2.2.9-1ubuntu2.1 secure POP3/IMAP server - core files ii dovecot-imapd 1:2.2.9-1ubuntu2.1 secure POP3/IMAP server - IMAP daemon ii dovecot-lmtpd 1:2.2.9-1ubuntu2.1 secure POP3/IMAP server - LMTP server ii dovecot-managesieved 1:2.2.9-1ubuntu2.1 secure POP3/IMAP server - ManageSieve server ii dovecot-sieve 1:2.2.9-1ubuntu2.1 secure POP3/IMAP server - Sieve filters support ii dovecot-solr 1:2.2.9-1ubuntu2.1 secure POP3/IMAP server - Solr support

So rather than the stock

_sudo apt-get install dovecot-imapd dovecot-sieve dovecot-antispam dovecot-managesieved dovecot-lmtpd dovecot-solr_

one would install _dovecot_ from the MAMARLEY PPA ? To integrate cleanly it would have to "Provides: dovecot-common" and "Replaces: dovecot-common, mailavenger" like the stock dovecot-core does. While we can and do use non-stock packages, we really try to stay with stock(ish) packages as much as possible to ease upgrade administration. I'm dealing with a slew of custom apache2 installs, all unique, on a bunch of old Cent 5.2 boxes right now, and it's a mighty pain.

I have a similar setup and have been getting the same errors about replicator-doveadm permissions on 2.2.12. I found this message in the list archives which say's its not important

http://www.dovecot.org/list/dovecot/2013-April/089559.html

and suggests changing the permissions on the socket. The right permissions would depend on which user(s) the doveadm-server process doing the sync is running as. From your questions below it looks like you are using virtual users with the vmail user owning the mailboxes, try

service replicator { unix_listener replicator-doveadm { mode = 0660 group = vmail } }

...

...

2. Question (much more important):

We are using sieve scripts for our users, they are replicated to the replica-host but this errors appears in logs on every synchronized message:

---8<---------------------------------------------------------------------- dsync-server(email@example.com): Error: Failed to access mailbox dovecot/sieve: Internal error occurred. Refer to server log for more information.

dsync-server(email@example.com): Error: stat(/var/vmail/example.com/email/.dovecot.sieve/tmp) failed: Not a directory

---8<----------------------------------------------------------------------

Any hints?

It looks like it thinks the .dovecot.sieve file should be a Maildir. Are you using the Maildir++ format for your mail stores? That uses "." as a separator for mailbox names. You might want to try changing the "sieve" config option from ".dovecot.sieve" to something which doesn't contain dots and rename the files to match.

I'm using "/" as separator ("separator = /" in configuration).. SO it shouldn't be the problem..

That parameter controls how the mailbox names are presented over IMAP, not how they are stored on disk. If you run "doveadm mailbox list -u email@example.com" you'll get a list like

INBOX Sent Drafts MailingLists/dovecot

etc, but if you look in /var/vmail/example.com/email you'll see something like

cur/ new/ tmp/ .Sent/ .Drafts/ .MailingList.dovecot/

If you add LAYOUT=fs to the mail_location option it will store the mailboxes as a directory hierarchy. You'll need to convert all the mailboxes to the new layout, changing the sieve file name will be much less work.

http://wiki2.dovecot.org/MailLocation/Maildir

Is your sync up and running? With sieve scripts?

Yes, my sync works. I don't use sieve though.
