[Dovecot-news] v2.2.beta2 released

http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta2.tar.gz
http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta2.tar.gz.sig

A ton of fixes since beta1. Especially the new dsync and the replication server
related to that should really work now. It also works correctly now for shared
mailboxes with private \Seen flags. And the replication server uses incremental
syncing after the initial full sync, so it should be pretty efficient also.

I've only two things left to do before v2.2.rc1:

1. Implement dsync to work via TCP and TCP+SSL sockets. This is pretty easy to
do actually, since it can use the existing doveadm-server to start up.

2. Read up all the pending mails from Dovecot mailing list and fix up the
reported issues. Actually I guess most of those are for v2.1, but still I should
get around to it. :)

There shouldn't be any major bugs left, so I'm expecting v2.2.rc1 out in
maybe a week or so, hopefully followed by the final v2.2.0 soon afterwards.
Please test and report any bugs found!

[Dovecot] v2.2.beta2 released

I've been running 2.2beta1 in production since it got out and I haven't
had
any issues. However, my setup is simply IMAP/POP3 without any complicated
configurations. This is on FreeBSD 8.3-STABLE with about 100 users.
I've just updated to 2.2b2...

I am running v2.2beta1 for almost a week now (handful of users, ~1000
mails/day). And yes, I can confirm that replication works ...
> Please test and report any bugs found!
... there is only a "feature request" left:

I did run a lot of stress tests as mentioned before (simultaneously injected
local mail).

Whenever I do run those tests with a delay of 1 second between every injection,
I do observe, that not all mails injected become visible in my MUAs (Mail.app
and Roundcube), immediately. All "get new mail" functionality or MUA
restarts fails to fetch those missing messages from both servers.

But, if I do restart any one of both dovecot servers involved, those remaining
missing messages are fetched instantaneously. It seems to me, as if those
missing messages were kept in the "replicator queue" and not delivered
to the partner server, and as if that queue became flushed during restart. After
restart all injected and replicated messages are accessible by the MUAs.

I never waited longer then 10 minutes before restarting dovecot, thus I do not
know if I didn't wait long enough. But I can say that an additionally
injected local mail shows up in both MUAs but doesn't become replicated.

Thus, if I am not mistaken that something like a "flushing" really
takes place, I wonder if there is a "doveadm flush replicator-queue"
functionality is available already (that I might have over-seen), and if not,
would that be a big deal to implement?

JFTR and with kind regards,
Michael

Hi,

I'm running dovecot 2.2b2 , for the first time, with vpopmail-auth and 
works fine.

But I found this bug, also present in 2.1.15. When I enable dict quota 
with mysql and in dovecot DB there is no entry for the user, dovecot 
waits 3 minutes and 30 seconds before create the entry and close telnet 
session:

   unix_listener auth-userdb {
     group = vchkpw
     mode = 0660
     user = vpopmail
   }
}
service dict {
   unix_listener dict {
     group = vchkpw
     mode = 0600
     user = vpopmail
   }
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
   args = quota_template=quota_rule=*:backend=%q
   driver = vpopmail
}
protocol imap {
   mail_plugins = quota imap_quota
}

I hope can be fixed.
Thanks
