[Dovecot] Auth error in log

[Per-Henrik Lundblom]

Hi,

I have a setup with Dovecot handling a few virtual domains delivering
mails to both local Unix account mailboxes and seperate mailboxes for
virtual users defined in a MySQL database. A quick overview of the
configuration shows two passdb definitions:

auth default {
  mechanisms = plain login

  passdb pam {
args = dovecot
  }

  passdb sql {
args = /etc/dovecot/dovecot-sql.conf
  }

  userdb passwd {
args = mail=maildir:~/Maildir blocking=yes
  }

  userdb static {
args = uid=vmail gid=mail home=/var/spool/vmail/%d/%n allow_all_users=yes
  }

  user = root

  socket listen {
master {
  path = /var/run/dovecot/auth-master
  mode = 0600
  user = vmail
  group = mail
}
client {
  path = /var/spool/postfix/private/auth
  mode = 0660
  user = postfix
  group = postfix
}
  }
  !include_try /etc/dovecot/auth.d/*.auth
}

When a virtual user defined in the MySQL database tries to log in using
IMAP or SMTP I always get auth failures logged in the system logs.
Entries are like this:

Aug 21 06:25:36 roadrunner dovecot-auth: pam_unix(dovecot:auth):
authentication failure; logname= uid=0 euid=0 tty=dovecot
ruser=lu...@mydomain.com rhost=85.224.xx.xx

I assume these failures comes form the fact that PAM doesn't recognize
the virtual users and Dovecot continues to the SQL passdb entry. As a
result I get a _lot_ of auth failures in the logs.

I have tried to come up with a way where the auth failures from PAM
arent't logged if the the SQL authenication is successful. Is this
possible or are there any other recommended ways to handle this?

That's pretty normal for virtual users. All my virtual users are 
u...@domain.tld/password.

Otherwise you would have collisions between, for example, i...@example.com and 
i...@example.net

Re: [Dovecot] Dovecot Dsync

[Ben]

perhaps many people are on holidays in summer,
however seems in your orig post you used 2.0.19 version
there were a lot of updates perhaps first update 2.1.17 or 2.2.5 then retry


True true... although from my point of view its hard not to be tempted 
to use rsync or something else that I know.  But as I said to a previous 
respondent, I'm keen to get to know (and hopefully love) my new dovecot 
install !


I'm on an Ubuntu LTS release so the dovecot came from their release. I'd 
prefer to stay that way unless I really have to...especially if the only 
reason for doing so is to fix Dsync. 2.0.19 seems to otherwise working 
ok !  Maybe I'll have a look through the release notes on a rainy day !




also seems you have some permission problems

failed: Permission denied (euid=1002(its_scripts) egid=1002(its_scripts)
missing +r perm: /var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755)


Hmmm... I think I tried that at some point, I think that was when the 
problem might have morphed into ...


dsync(its-virtmail): Error: user t...@somewhere.example.com: 
Initialization failed: mail_location not set and autodetection failed: 
Mail storage autodetection failed with home=/srv/mail/example.com/test

dsync(its-virtmail): Fatal: User init failed
dsync-local(t...@somewhere.example.com): Error: read() from worker 
server failed: EOF


But I'll give it another go tomorrow.

Re: [Dovecot] Dovecot Dsync

[Ben]

Maybe everyone is waiting for someone smarter than themselves to answer
this.. :-)


Maybe... but at the same time, there's a risk of me abandoning Dsync for 
rsync or something else that I know I could have implemented by now with 
far less frustration ! However I'm keen to learn how to utilise the 
power within Dsync ;-)




So.. hoping I read and understood your email correctly ...


Hoping that email wasn't too confusing ;-(



The first thing you tried failed because only root can change
permissions, except for using the setuid bit which is probably not what
you want here.
The second might have failed because of:

userdb {
   args = username_format=%u /etc/dovecot/users
   driver = passwd-file
}

dsync is using userdb and not authdb because it's not checking a
password here. Can it be that its-virtmail doesn't have permission to
read /etc/dovecot/users ?


hmmm ... its chmod 640 root:dovecot on the primary server and the same 
on the backup box.  Do I need to mess around with permissions on both or 
just the backup box ?


I was under the impression that Dsync was just a more modern version of 
a doveadm tool that went by a similar name and hence assumed it would 
use dovecot permissions.


But then again, who knows... I was getting very confused at the end of a 
long day trying to make it work !

[Dovecot] Delivering message to other mailbox

[Frank de Bot]

Hi,

On my mailserver I have for each mailbox a sieve script to put 
Spam-marked message into a folder (match header, then fileinto 'Spam').


This works, but I want to deliver spam-marked messages to a different 
mailbox.
For each user a seperate mailbox is created next to the existing 
mailbox, allowing different authentication.


How can I do this with dovecot/pigeonhole? I figured out I could 
redirect is the user.spam@domain which delivers to the other mailbox, 
but it will go into a new delivery process with amavis set up. (There's

Is there a way I can accomplish to directly deliver a spam-marked 
message to a different mailbox?

opencsw.org might have dovecot 2.2.4 for Solaris 8
You might need lots of dependencies if you have not used opencsw before, 
but their pkg installer should take care of them too.
They also have newer versions of gcc, if you still prefer to compile 
2.2.5 from source.

Hello Luciano,

Wouldn't

unsigned char * prefix_text

be equivalent in such a context?

Ah, that is nice. I can run through my procmail recipes and then to dovecot-lda

dovecot-lda -o setflag="\\Seen"?

Your passwd contains the user with @domain?

I don't think so.


you tried to auth as user eric...@metropolitan.org.za via PAM, but 
your /etc/passwd would know erickom only. Hence, try to auth without 
domain.



I uncommented the above

# In many systems nowadays this uses Name Service Switch, which is
# configured in /etc/nsswitch.conf. 
passdb {

Now you try with another passwd driver and access /etc/passwd without

Your passwd contains the user with @domain?

I don't think so.


you tried to auth as user eric...@metropolitan.org.za via PAM, but your 
/etc/passwd would know erickom only. Hence, try to auth without domain.



I uncommented the above
# System users (NSS, /etc/passwd, or similiar).
# In many systems nowadays this uses Name Service Switch, which is
# configured in /etc/nsswitch.conf. 
passdb {
 driver = passwd
 # [blocking=no]

and commented the pam authentication.

Now you try with another passwd driver and access /etc/passwd without PAM, 
but you have a shadowed passwd system. Revert to passdb pam and try the 
username without domain.

I am assuming that sieve acts as a LDA like procmail, so it's an either/or? I 
have a *lot* of procmail recipes I've written over the last 20 years or so.


you could mangle the flags in the filename yourself:

append :2, unless a : is present already
append S for seen

move from new to cur filename =~ s!/new/!/cur/!

The flags following the "," _should_ be sorted, but Dovecot does not rely 
on it, IMHO.


Oh, websearch found: 
http://www.dovecot.org/list/dovecot/2009-January/036297.html


Then there is

doveadm flags add -u user '\Seen' mailbox XYZ header message-id ABC

or something like that.

Not entirely sure I'd call it "the default", Thunderbird seems to setup for 
IDLE as default these days, and I suspect Apple Mail and any of the other 
popular ones do too.


Thunderbird can IDLE since long time, but does polling, if the number of 
allowed connections is exceeded. So, IDLE or polling is transparent to the 
users, except if some new-message indicator is not as quick as usual.


IMHO, this behaviour is the "default", if one will named it as such, 
because it makes the most sense and an ordinary user is not able to choose 
correctly, most of the time.


If somebody has already prepared a paper, when the load of x IDLE 
connections exceeds the load of polling of x folders for an amount of y 
simultaneous users? :-)

Not nesessarily, you can make procmail hand over the message to dovecot-lda
if you like:

Something lik this:

DELIVER="/usr/lib/dovecot/dovecot-lda"

:0
* ^X-RSS-Feed: .*rss2email
| $DELIVER -m System.rss2email/

works flawless.

This example is af course very symplified, I still use a nice procmail
script to filter uot all my maillists befor handing over the rest to
dovecot.

should not be difficult to implement

dbmail has a setting after a feature-request from me because
the "smart" Apple Mail resulted in crashing the server multiple
times by a user on the LAN who draged the wrong attachment to
a new message which was a some GB large video and Apple insists
trying to save the draft each time the server comes back

dbmail.conf:
max_message_size = 36700160

[Dovecot] Question: dovecot-1.2.17 , pop3

[Kutrus Neloy]

Hi,

you have written in your Dovecot 2.2.5 - Changelog that you have solved a
Problem with pop3.
*· pop3: Avoid assert-crash if client disconnects during LIST.*

My question is:
Is it possible to get this problem with my version? 1.2.17 ?

Thanks

[Dovecot] Rfc: Limit the size of an email IN the mailbox

[Ralf Hildebrandt]

Currently we're in the process of migrating Dovecot mailboxes to
Exchange. 

This is all working very well, except for the occasional user, who used
his/her Drafts folder as a file storage: They started writing an email
containing lots of image attachments (and thus exceeding our
maximum_message_size by far). So the mail never gets sent, but stays in
the Drafts folder.

Once I try moving that mail to exchange, it won't accept the message
since it's too big. I think it would be interesting to have a limit on
the total size of an IMAP object, just like in SMTP.

Thought?

I haven't looked at a recent fresh install config of TB.  If they have
started enabling IDLE by default it's recently, and they'd have been
required to increase the default 5 cached connections.  Otherwise many
folk would never see new mail notification on some of their server side
sorted folders.  And Joe and Susie Sixpack have no knowledge of the
relationship between connection (socket) count and IDLE requirements,
and I'd guess no MUA has documentation explaining this.  I'm pretty sure
Mozilla does not.  I'm sure there are forum posts about it, but I doubt
official documentation exists.

For IDLE to work seamlessly requires basically 3 things:

1.  MUA counts all IMAP folders and
2.  Always maintains $folder_count sockets
3.  IMAP servers must allow basically unlimited sockets

In a closed environment such as a corp/uni this can be achieved, and
without unlimited sockets, if staff can enforce a limit on folder count.
 In an open environment such as an ISP or freemail provider, they'd have
to allow unlimited sockets.  Some may do so currently.  I have no
knowledge of what such providers are doing in this regard as I don't use
them nor support anyone who does.
