Limit replication to one user

2016-09-14 Thread Arne Hoffmann 
Hello, 

we have a setup here where the main (and only important) feature of the IMAP
server is the public folder. Two Dovecot instances are running in a
active/passive cluster and mailstorage should be replicated between the two. 

Since there is a race condition when using public namespaces (locking on
user level and not on mailbox level) I had the intention of limiting the
replication to one user. 

I read somewhere that dsync is replicating all the users the command
"doveadm user '*'" shows. And the command only shows *one* user because I
have modified the iterate_query: 


,[/etc/dovecot/mysql.conf]
| iterate_query  = SELECT username AS user FROM mailbox WHERE username = 
'data_replicat...@example.com'
`


root [~]# doveadm user '*'
data_replicat...@example.com 
root [~]#


So, why does Dovecot still replicate mails from other users inboxes? And why
does doveadm replicator still show other users? 


root [~]# doveadm replicator status '*'
username  priority fast sync full sync success sync 
failed
data_replicat...@example.com  none 00:57:14  01:13:21  00:57:12 -
arne.hoffm...@example.com none 00:20:04  00:31:40  00:20:02 -
root [~]#


[I removed some whitespace to keep line length in check] 


Any explanation of this behavior would be just awesome. Hints to possible 
solution even more! :)

Sure! It seems better suited to pastebin:

Thanks for any help!

No Autoindex?

2016-09-14 Thread Larry Rosenman 
I used to get my mail auto-indexed, but something(tm) changed recently, but
I'm
not sure what.

I do have fts_autoindex = yes in my dovecot config, and if I do a doveadm
index \*
it does the index.

Ideas?

 Hello Timo,

 with the newly build CSW-package the crashes still occur, today already
 twice within two hours. The log shows always the same:

 This happens with different users, the last one with a relatively small
 mailbox of 600MB.

 doveconf -n is attached.

 Dovecot 2.2.25
 OS: Solaris 11 (SunOS 5.11 11.3 i86pc i386 i86pc)
 Virtualization: VMware
 Filesystem: ZFS
 active users: ~4000

 The system was transferred at beginning of last week from an old
 SPARC-station with Solaris 10 running dovecot-2.2.15 to this virtualized
 platform under VMware. The mailboxes (maildir-format) were transferred
 without change by switching the storage-hardware to the new server. I
 had to remove all dovecot.index*-files for errors of "CPU Architecture
 changed", but after doing this all seemed to work ok except for these
 occasional crashes.

 If you need more information, please let me know.

 Thanks for any help,
 Andreas

Hello and thanks for this information,

the OpenCSW-maintainer has implemented this fix into another test
version, which is now running on my production system. I'll report, if
there are any more problems.

Best regards,
Andreas
