I noticed that dovecot is creating user directory structures

though we have setup a static users.conf db file.



I tried omiting the "allow_all_users=yes" parameter but
that doesn't seem to be linked to this issue


What is the problem / question actually?


Sorry if this has been asked a number of times already
Is there an easy way to search the archives of this

Google or any other search engine, maybe limit the search to

The SEEN status is "encoded" in the filesystem in Maildir not Dovecot

I then usually just run the sieve-test binary (part of the Pigeonhole

there maybe a way for them to try it themselves? Like, maybe a tiny web

wonder how other people do that.


you are not referring to syntax errors, do you?

Otherwise, this seems to be a nice idea to let users actually _test_ their 
scripts. However, I wonder how educated they are, in order to paste in a 
correct "mail file" incl. header and the like.

Hi Timo,

thank you very much for fixing the issue. I can also confirm that it
solves the issue I experienced on a test machine after installing 2.2.3.

Thanks, yes, I figured it out from a similar discussion going on in here
last week. I just created an empty "dovecot-shared" file in that mailbox
and it worked like a charm. Checked the docs later - the phrasing
that mentions this file is not too clear, maybe adding a note like "make
sure you create this (empty) file in the mailbox" would help.

Anyway, from the info I gathered, I assume my concept of providing
a shared INBOX should work with no problems which is great.

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'

[Dimos Alevizos]

Hello,

we're having some problems with our dovecot setup.
I've seen similar problems in the mailing list some years ago but alas 
wasn't able to find a solution.


Our setup is as follows :
An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 
2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 
2.1.16).

All mailboxes and indexes are on NFS and all servers are Centos.

The problem is that at times we see mailboxes (all of them are in mbox 
format) beginning with FFrom or FrFrom and of course dovecot says it's 
not a valid mbox file.
If we manually remove the offending extra characters from the beginning 
of the file everything is working again, but often the same user will 
show the problem again tomorrow.
However it's very rare and so far we haven't been able to reproduce the 
problem.


After activating the mail_log plugin hoping it'll help us locate the 
problem we run across this case :


The user (let's call him u...@domain.gr) logs in via pop3 and deletes 
some mails but one of them fails:

[Dovecot] Sieve file permission problem

[Zoltan Lippai]

Hi folks, 

I am using dovecot 2.1.7 with the ManageSieve plugin which works great. 
Recently I set up Afterlogic webmail on my server (the community version) and 
it has a nice UI to manage the sieve settings. It uses port 2000 to communicate 
with dovecot via the ManageSieve plugin. Also, dovecot uses Maildirs to store 
the messages.

The problem is that the permissions on the files that store the sieve rules are 
to strict.
I am talking about the "sieve" directory and the .dovecot.sieve file. 
The sieve folder has a chmod 700 and the .dovecot.sieve is chmod 600. Both are 
owned by vmail:mail

If I delete these two items, then the rules can be saved via the web interface. 
Then these files are created but for some reason the ManageSieve plugin can't 
modify them.

Here is the output of dovecot -n:
http://pastebin.com/4eqyBKCA

Can you help me out on this?

Thanks a lot!
Zoltan

Are you planning to make a new (minor) release of pigeonhole soon, just

[Dovecot] Dovecot proxy to Microsoft Exchange 2013

[Ricardo Machini Barbosa]

Hello,

I am trying to do a proxy with dovecot to IMAP backend server that are 
using Microsoft Exchange 2013.
I already did this with Microsoft Exchange 2007 and Microsoft Exchange 
2010 and it works perfectly! But with Microsoft Exchange 2013 I can not 
perform LOGIN.


The error log message is:
/imap-login: Error: proxy(u...@domain.com.br): Login for 
exchange2013.domain.com.br:143 timed out in state=4 (after 30 secs, 
local=x.x.x.x:59640)/


My troubleshoot was:

- tcpdump on dovecot server side:
I can see the commands sent/received by Microsoft Exchange. But no 
the "OK LOGIN" response.


/* OK The Microsoft Exchange IMAP4 service in  is ready.//
//C CAPABILITY//
//L LOGIN "u...@domain.com.br" "123456"//
//* CAPABILITY IMAP4 IMAP4rev1 AUTH=PLAIN STARTTLS UIDPLUS CHILDREN IDLE 
NAMESPACE LITERAL+//

//C OK CAPABILITY completed./

- tcpdump with telnet login on dovecot server side:
Works fine.

/* OK The Microsoft Exchange IMAP4 service in  is ready.//
//a login "u...@domain.com.br" "123456"//
//a OK LOGIN completed.//
//a logout//
//* BYE Microsoft Exchange Server 2013 IMAP4 server signing off.//
//a OK LOGOUT completed./

- Log verbose on Microsoft Exchange 2013.
Look like that Microsoft Exchange did not receive the login command.

Someone already tried do this with Microsoft Exchange 2013 ?

See bellow some information about my dovecot configuration:

[Dovecot] Calling dovecot-lda from within Antispam pipe script (bash) seems to have no effect

[Ben Johnson]

Hello,

I'm attempting to configure the Dovecot Antispam plug-in on Ubuntu 12.04
LTS with Dovecot 2.0.19.

Everything seems to be in order with one considerable exception: when my
pipe script (a simple Bash shell script) calls the dovecot-lda
executable, absolutely nothing seems to result.

If I copy/paste the exact same command into the terminal, the mail is
delivered to the target mailbox, as expected.

Here's my pipe script: http://pastebin.com/DBXAZqsN

When I move a message from INBOX -> Junk, or from Junk -> INBOX, the
pipe script is called, and here's the output:

---
31465-start (--debug --username=amavis --ham)
Checking if the command-line input argument string (--debug
--username=amavis --ham) contains the string "ham" or "spam"
Mode is "HAM"
Calling (as user vmail) '/usr/lib/dovecot/deliver -d
"sa-train...@example.com" -m "Training.HAM" -p
"/tmp/sendmail-msg-31465.txt"'
31465-end
---

But, for some reason, the call to "/usr/lib/dovecot/deliver" doesn't
seem to do anything.

If I copy the above output and paste it into the terminal:

/usr/lib/dovecot/deliver -d "sa-train...@example.com" -m "Training.HAM"
-p "/tmp/sendmail-msg-31465.txt"

Dovecot does indeed deliver the message. This works whether I execute
the above command as "root" or "vmail".

Why does this command have no effect when called from within the pipe
script?

Here is my "doveconf -n" output:

[Dovecot] pop3 and imap don't run

[Dovecot] mail_max_userip_connections on a per user basis

[Antonio Leding]

Hello,

Can the above setting be applied on a per user account basis?

I thought that maybe something like per account quotas might be a possible 
method but not sure.

Thanks.

[Dovecot] Sieve Plugin Setup

[Denny Jones]

I've got an existing setup that I want to add Sieve filtering to. I'm on 
QmailToaster:

qmailadmin-toaster-1.2.16-1.4.0

I using Dovecot version 2.0.11

I'm looking for a good tutorial for installing Sieve Rules functionality on an 
existing system. Anybody know of one? Anybody else done this? Do I just install 
the latest Dovecot-sieve plugin release with wget, etc? What kind of 
configuration can I expect to have to go through. Do I have to reconfigure 
Dovecot to work in conjunction with the Sieve plugin?

I'm hoping to find someone else has done this that can help me navigate the 
waters so-to-speak.

Thanks in advance,
Denny

Re: [Dovecot] Calling dovecot-lda from within Antispam pipe script (bash) seems to have no effect

[Bob Miller]

Hi Ben,

I checked over your script, and I don't see the problem either.  You
already checked everything that comes to my mind.

Maybe using something like set -e to try and get some output from the
script?
