 These days, you *really* should be using QRESYNC instead though.


 There are some mail servers that support CONDSTORE but not QRESYNC. The
 old
 chicken and egg IMAP problem :)


 [ snip ]
 Both Dovecot and Cyrus support both CONDSTORE and QRESYNC, and combined
 that is more than 50% market share, so that should be incentive enough.
  Gmail only supports CONDSTORE, but it's the outlier.


Gmail still does have a few users, though. A few dozen at least, maybe more
:)

And it has a big advantage, from my point of view, over Cyrus / Dovecot --
there is but one server version that's consistent for all accounts.

Yes, they do some things wrong (like not sending message flags changes over
IDLE connections), but I can test something in my personal account, get
feedback from 3-5-10 users with @gmail accounts, and be reasonably
confident that everything is fine (and that I'd know know if it's not).

Now, Cyrus and Dovecot (and Courier I guess) is a different story, there is
a variety of versions out there, and software being software, there may be
bugs / glitches / quirks.

Since you mention Cyrus, do you know that it often (like, almost always)
responds to ID with a NO? This is not RFC compliant, but it's what is
actually does.

For the more than 50% market share of Dovecot / Cyrus, do you have a
breakdown by version number? At least in terms of 1.* vs 2.0 and higher?




  So let me try again:

 Is sending SELECT ... (CONDSTORE) or STATUS (... HIGHESTMODSEQ ...) enough
 to enable reliable persistent modseq tracking for all versions of Dovecot
 which advertise CONDSTORE in their capabilities?


 Maybe.  You can't tell until you actually see whether the EXAMINE/SELECT
 returns HIGHESTMODSEQ or NOMODSEQ.


Are you saying that Dovecot will always (*will always*, and I mean
*always*) return NOMODSEQ after a client expresses interested in modseq
values and the server can't enable it for some reason?

Or if it was previously enabled, and then well, I don't know, something
happened?

By *always* I mean -- since Dovecot first started having a CONDSTORE in its
CAPS, including version a.b.c that came with now really old Debian X, and
version h.j.k that came with now really old RHEL Y, but which are still out
there on actual mail servers, being used in actual mail accounts?

When something goes wrong in an email app, then to the user, it's always
the email app developer's fault. Nobody gives a damn about the subtleties
of what RFC abc says about xyz, or if server version j.k.l from three years
ago had a bug.

So, before enabling certain optimizations for Dovecot, I thought I'd ask on
a Dovecot mailing list, about actual behavior for this server feature.

I assume this mailing list has people with real Dovecot experience and
knowledge, and maybe even the developers are lurking here too.

Specifically, I was hoping to hear back maybe something like this:

Dovecot version X which was packaged in Debian Z, would not update the
modseq value after command Y.

Or maybe -- which would be great:

There were no issues with modseq tracking, at all, no reported bugs, code
not touched, since the feature was originally implemented and advertised as
CONDSTORE in CAPS in version 1.2.*.

Re: Flags in public folders disappear when more than 25 flags are used

2014-07-10 Thread Thomas Herrmann 
On 08.07.2014 17:01, Thomas Herrmann wrote:
 Now I am a little closer to the problem. I discovered that the
 dovecot-keywords file is out of sync with what doveadm reports. Is that
 a problem? 

To continue my monologue, this does not seem to be a problem. The
numbering in the dovecot-keywords is different from the ones reported by
doveadm in almost all of my folders.

Now that I am using 2.2.13, I have observed this:

- The flags that are present in the dovecot-keywords are synced between
all clients.
- The flags that are not in the dovecot-keywords files are not synced
between clients, they are in fact per-user keywords (I use per-user seen
flags for the public folders). When I set the keywords, I see changes in
the dovecot.index.* files located at /home/vmail/adwin.de/%n/public,
while that information should be stored at /home/vmail/public.

Maybe this happens because I am using 2.2.* with INDEX instead of
INDEXPVT, so now my question is, how do I upgrade from INDEX to INDEXPVT
without losing information? Will dovecot convert the old files
automatically? I did not find anything about that at
http://wiki2.dovecot.org/Upgrading/2.2

Re: BUG: Authentication client sent unknown handshake command

You have misconfigured Dovecot's auth sockets. Providing doveconf -n output 
would help figuring out the problem. Or just delete all the auth-related socket 
settings from config files and it should work.

 I'm transitioning my server over from using the deliver LDA and LMTP.  
 Suddenly a bunch of sieve filters stopped working, and I noticed the contents

 Using Dovecot's deliver LDA, the contents are a bare email address 
 (f...@bar.com).  Using Dovecot LMTP, they are in brackets (f...@bar.com).  
 Is there a reason why this isn't consistent between the two delivery agents?  
 It seems like it ought to be.

Oh, that's annoying. Dovecot LDA doesn't actually add this header, it was your 
MTA that added it. But looks like I hadn't checked what the MTAs actually write 
to the header when I added this feature to LMTP, and nobody had mentioned this 
before either. I wonder if anybody's system breaks if I just change it now..

 Now that I am using 2.2.13, I have observed this:
 
 - The flags that are present in the dovecot-keywords are synced between
 all clients.
 - The flags that are not in the dovecot-keywords files are not synced
 between clients, they are in fact per-user keywords (I use per-user seen
 flags for the public folders). When I set the keywords, I see changes in
 the dovecot.index.* files located at /home/vmail/adwin.de/%n/public,
 while that information should be stored at /home/vmail/public.
 
 Maybe this happens because I am using 2.2.* with INDEX instead of
 INDEXPVT,

Right.

 so now my question is, how do I upgrade from INDEX to INDEXPVT
 without losing information? Will dovecot convert the old files
 automatically? I did not find anything about that at

I think it would work if you simply change INDEX - INDEXPVT, but test first 
with some test users.

Re: Differences in Delivered-To header between deliver and LMTP

2014-07-10 Thread Jeff Rice 
I don't know if there is a convention for whether the brackets should be 
included or not.  But consistency is a virtue.  The MTA in question is 
Postfix 2.9.6.  I assumed it was the Dovecot LDA adding the Delivered-To 
header because it was rewritten when I did a redirect in sieve, but 
redirect must put the message back into Postfix's queue where the header 
gets added (or replaced, in this case).


Maybe other folks can chime in if they see emails in brackets () or 
not for this type of header for other MTAs and we can get a sense of 
which is more common.


Jeff


Timo Sirainen mailto:t...@iki.fi

Oh, that's annoying. Dovecot LDA doesn't actually add this header, it 
was your MTA that added it. But looks like I hadn't checked what the 
MTAs actually write to the header when I added this feature to LMTP, 
and nobody had mentioned this before either. I wonder if anybody's 
system breaks if I just change it now..


Jeff Rice mailto:j...@jrice.me
July 9, 2014 at 2:20 PM
Hi,
I'm transitioning my server over from using the deliver LDA and LMTP.  
Suddenly a bunch of sieve filters stopped working, and I noticed the 
contents of the Delivered-To header are different.


Using Dovecot's deliver LDA, the contents are a bare email address 
(f...@bar.com).  Using Dovecot LMTP, they are in brackets 
(f...@bar.com).  Is there a reason why this isn't consistent between 
the two delivery agents?  It seems like it ought to be.

dovecot lda invalid user settings

2014-07-10 Thread CJ Keist 
I'm now dealing with issue with some users on mbox getting invalid user 
settings in /var/adm/messages.  /var/log/syslog has:


Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.error] lda(ejames):

Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.crit] lda(ejames): Fatal: 
Invalid user settings. Refer to server log for more information.


I checked this users home directory and the mail folder is there and 
permissions are all correct.



I'm running in a mixed mbox and Maildir environment. I read to support 
this environment you simply comment out the mail_location lines in 
10-mail.conf file which will force dovecot to auto detect what format a 
user is using.  This worked fine in dovecot 1.2.12, but seems to failing 
here.

Re: Differences in Delivered-To header between deliver and LMTP

2014-07-10 Thread Larry Rosenman 
There is no Delivered-To: in Exim, there is an Envelope-To: which is
added withOUT the
the angle-brackets()

Return-path: bo-b685yaba89pstxauy6speqcc659...@b.emails.containerstore.com
Envelope-to: pare...@lerctr.org
Delivery-date: Thu, 10 Jul 2014 12:17:54 -0500

Does that help?

 I don't know if there is a convention for whether the brackets should be
 included or not.  But consistency is a virtue.  The MTA in question is
 Postfix 2.9.6.  I assumed it was the Dovecot LDA adding the Delivered-To
 header because it was rewritten when I did a redirect in sieve, but
 redirect must put the message back into Postfix's queue where the header
 gets added (or replaced, in this case).

 Maybe other folks can chime in if they see emails in brackets () or not
 for this type of header for other MTAs and we can get a sense of which is
 more common.

 Oh, that's annoying. Dovecot LDA doesn't actually add this header, it was
 your MTA that added it. But looks like I hadn't checked what the MTAs
 actually write to the header when I added this feature to LMTP, and nobody
 had mentioned this before either. I wonder if anybody's system breaks if I
 just change it now..

 Jeff Rice mailto:j...@jrice.me

 Hi,

 I'm transitioning my server over from using the deliver LDA and LMTP.
  Suddenly a bunch of sieve filters stopped working, and I noticed the
 contents of the Delivered-To header are different.

 Using Dovecot's deliver LDA, the contents are a bare email address (
 f...@bar.com).  Using Dovecot LMTP, they are in brackets (f...@bar.com).
  Is there a reason why this isn't consistent between the two delivery
 agents?  It seems like it ought to be.

 Jeff

Hi,

not shure if that helps.

In 10-master.conf file exists a service imap { ... } section.
You could try to increase the process_limit =  parameter in it.

On one of oour servers there we have process_limit = 2048 and we habe 
about 1200 concurrent connections without problems.


Best,
Urban

Update: I had to fall back to the 1.2.17 dovecot code.  Doing that 
solved the invalid user settings and dovecot inability to auto detect 
between mbox and Maildir format for user accounts and no longer have the 
limited number of imap processes either.


Not sure what I was missing in the config files, but this is the route I 
will stay on for now. If it helps here is the 1.2.17 config:

That didn't work. Still seem to stop accepting new imap connections when
we hit around 500 processes.

Hi,

not shure if that helps.

In 10-master.conf file exists a service imap { ... } section.
You could try to increase the process_limit =  parameter in it.

On one of oour servers there we have process_limit = 2048 and we habe
about 1200 concurrent connections without problems.

Best,
Urban

It's not fixed. Now the limit looks to be around 500 processes and we
start to get number of connections exceeded.  Any ideas?

I fixed this issue about the process limit in the 10-master.conf file:

default_process_limit = 5000
default_client_limit = 3

It looks like on the system that once we hit around 200 imap processes
it stops there and no more imap processes can be created.  Is there a
number of max imap processes in the config file somewhere.  By the way
running on OmniOS:

SunOS mail2 5.11 omnios-6de5e81 i86pc i386 i86pc

Thanks for the reply. I have seen threads about setting the

2014-07-10 Thread CJ Keist 

After starting dovecot the following is run to take care of the fd limit:

/usr/bin/plimit -n 16384,16384 `cat ../var/run/dovecot/master.pid`

I was doing this same commend for 2.2. dovecot as well.

I do have ssl configured and working.  My mail client confirms the 
secure connection is made.


Not sure why the dovecot -n showed double slash, it's not that way in 
the config file.
