Hello,

I'm seeing a lot of these in my /var/log/messages in Debian Squeeze, I 
suspect this might be causing performance issues. Any suggestions what 
I can try to fix this?



I'm using the 2.1.10 packages obtained with the following in my 
sources.list:


deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.1 main


I need to use Dovecot 2.1.x because I need to support handling 
multiple SSL certs.

May not be related at all, but when I see segfaults on Debian, the
first thing I try is to switch to bash as the default system shell:

dpkg-reconfigure dash

Answer: Use dash as the default system shell (/bin/sh)? 


Unfortunately this hasn't completely resolved the issue (I don't know if 
it has reduced the number of times this has happened either). FWIW I'm 
getting the same sort of segfault 28 with both imap-login and pop-login. 
I'm using dovecot-ldap, if that makes a difference. I'm not really sure 
what the best way would be to trace this problem so that I can provide 
you guys with more useful info.


P.S. sorry for the duplicate message, it seems to have something to do 
with attaching images to messages.

[Dovecot] Update: Hanging IMAP sessions on Mac OS X with dovecot 2.1.10 - worked fine with 2.0.15 (and 2.0.21)

2012-09-22 Thread Clemens Schrimpe 
Update: I tried with 2.0.21 and this also works just fine. So it must be 
something which came in with 2.1.x

PS: Where is the documentaion for 2.1.x - i.e. for all the nice additions Timo 
made? The Website "only" has 2.0.x, as far as I can tell?
(might be wrong here - hadn't touched the whole thing for a while, as my "civil

Oh d'oh. Yes, it related to that. I fixed it for Dovecot v2.2 before,
but I forgot the Dovecot v2.1 tree. Fixed now:

D'oh, this is the v2.2 change. The URL I meant is this one:

This only happens when you compile against installed Dovecot headers,
people using --with-dovecot= (like me) would not have seen this.

I'll push out a new release once 2.1.10 comes out. I'm being told that
is imminent.


Sorry, but using the new 0.3.3 version I'm getting the same error and
I'm also using --with-dovecot=... with the dovecot 2.1.10 tree in
configure, not the installed headers. If needed I can send you the
configure invocation command.


Yes, that could be helpful.

Stephan.

Both of these would require adding some kind of new command parameter parsing. 
Currently shell does all the "multi word string" parsing and escaping and such. 
My original thought was also to be able to read commands from stdin, but I'd 
rather not add such special command parser, at least not yet..

v2.1.10 already has "dovecot exec" that does a different thing. So can't be 
anything related to "exec"..

[Dovecot] Hanging IMAP sessions on Mac OS X with dovecot 2.1.10 - worked fine with 2.0.15

2012-09-22 Thread Clemens Schrimpe 
Ok, here's a toughie:

Out of a whim (and because of the bad weather) I today decided to upgrade my 
completely functioning 2.0.15 installation on my Mac OS X 10.6.7 system. NB: 
It's not a Mac OS X "Server", as sold by Apple - I have compiled my dovecots 
myself for quite a while.

Anyhow: At first everything appeared to work fine after the upgrade. Up until I 
created a new user and -while testing- SELECTed his INBOX.
The SELECT was "stuck". Though the process seemed to be alive I could only get 
rid of it with a "kill -9 ".

The same happened when selecting a newly created mailbox on any of the other 
(otherwise functioning) accounts, so the problem had nothing to do with the new 
account, but rather with the fact, that it's INBOX was empty. 

Using dtruss and gdb I found out, that the dovecot process was trying to obtain 
a GUID and in the course of doing so invoked gethostbyname(), which intern 
caused a lot of "mach message" handling and somewhere, deep down there, the 
process was stuck.

Well, that led my to believe, that there was something wrong with the -so 
called- "mach bootstrap context". I usually start dovecot from with a 
(home-brewn) startup-script, which invokes it (practically) like so:

sudo /usr/libexec/StartupItemContext dovecot

(again: all this was working fine under 2.0.15)

Now with 2.1.10, when I manually invoke dovecot with just

sudo dovecot

Everything appears to work fine - at least the sessions don't get stuck any 
more. But as soon as I logout (with dovecot still running in the background) it 
loses it's "mach bootstrap context" and finds itself unable to perform even the 
simplest tasks, like mapping a username to a uid, etc. pp. -- so starting it 
without the "/usr/libexec/StartupItemContext" in the background is out of the 
question.


Now -with all that said- here's my question: 

What has changed with regards to "processual context" between 2.0.15 and 2.1.10 
when the "imap" process is spawned/exec'd? Any environmental cleanups, closing 
of unknown fds, deletion/modification of environment variables, 
process-group-handlers, etc.?

It appears, that the imap process no longer "inherits" the StartupItemContext 
from the main process, so some change between 2.0.15 and 2.1.10 must have 
broken it ... 


Any help is highly appreciated -

Clemens


PS: I google'd around a lot and searched the mailing-lists, of course. I only 
found a post of someone who ran into the same/similar problem dating back to 
Feb 21st 2012 under the subject "dovecot freezes when trying to get mail from 
maildir with mail", but it was quickly dismissed without ever getting resolved 
and that was that.

PS2: I intentionally didn't include any configs with this mail as they seem to 
be irrelevant, but of course I can generate the necessary output if needed.

[Dovecot] thunderbird does not copy a tree-structure to dovecot imap

2012-09-22 Thread Anton 
Hi,

running in problems with KMail I decided to switch to 
dovecot-imap & thunderbird on my kubuntu 12.04 64 bit
(so I can read my imap-folder-mails with KMail again if it gets more stable)

What I did:
 - I wrote a python script to convert my KMail mails folder to a 
   thunderbird mailfolder (directory tree containing mbox files 
   and *.sbd folders)

 - I created a fake pop mail account in thunderbird and imported the
   whole mail-structure (i just copied it)

 - I create a local imap account ( so I have a ~/Maildir dovecot 
   folder in my user dir)

 - In /etc/dovecot:

   1. /etc/dovecot/10-mail.conf (line 10) I set:
  mail_location = maildir:~/Maildir:LAYOUT=fs

   2. /etc/dovecot/20-imap.conf (line 57) I set:
  imap_client_workarounds = tb-extra-mailbox-sep

Now I want to copy the whole mailstructure from my imported
fake pop mailfolder to the dovecot imap folder.

What happens:

Lets say my source structure is

 mailfolder1
   + mail1
   + mail2
   + subMailFolder2
   + mail1-in-subMailFolder2
   + mail2-in-subMailFolder2
   + subSubMailFolder3
   + mail1-in-subMailFolder3
   + mail2-in-subMailFolder3

I thunderbird (version 15) I drag and drop my mailFolder1 
to the imap folder and I get:

 mailfolder1
   + mail1
   + mail2
   + subMailFolder2
   + subSubMailFolder3

as you See only the mails of the *TOP* folder are copied.
All subfolders are created but they contain NO MAILS.

Did somebody experience the same problem???

Otherwise I will write a python script to do that
(I dont hope to need to write a mailclient in python ;-) )

Any hint is greatly welcome.

[Dovecot] Spurious " Renaming not supported across conflicting directory permissions"

2012-09-22 Thread tlhackque 

Dovecot 2.1.10
Client = Thunderbird.  Local disks.  mbox format.

Attempted to rename a folder, failed with:

  CANNOT Renaming not supported across conflicting directory permissions

I don't understand why this should happen.
  o I was renaming within a directory - the attempt was to rename 
"Domain Names &- SSL Certificates" to "Domain Names".  No directory was 
specified
  o The reason the directory has g=s is for dovecot - so that the 
'mail' group (12) will stick to any files created.  I was getting more 
understandable permission failures before I added it.  Since 's' doesn't 
apply to files, I don't see why this should be viewed as a conflict.
  o If I chmod g-s the directory, the command succeeds.  But then I'm 
back to file ownership problems...
