Proxying when src and dest on non standard ports
Hello,
I want to test dovecot proxying, on a user basis, in a simple set up (proxy, no
proxy_maybe and forward the passwd to the remote server). This seem pretty
simple except that, in order to test it alongside the production server, I set
up 3 servers :
. the proxy, listening to pop and imap on non standard ports 9143, 9993, 9110, 9995
. a proxy destination for some users, listening on

Imap-login service count/limits
Hello Timo,
I'm trying to configure dovecot-2.1.15 master correctly regarding imap-login
limits. I want to use service_count=0 and I'm starting with something like this
:
#default_process_limit = 100
#default_client_limit = 1000
service imap-login {

service_count = 0
process_min_avail = 8
vsz_limit = 1024M
}

Maildirs location migration
Hello Timo,
I'm using dovecot-2.1.15 with Maildir mailboxes located on an NFS filer.
Postfix is used to deliver mail through procmail ("mailbox_command) as LDA.
Our team has bought another filer and everything is meant to go on it, so we're
planning to migrate those mailboxes to the new filer.
To test it only on a subset of users, I ended up to the following solution :

dovecot backend on director ?
Hello Timo,
The last time I checked my understanding about director was that :
1. backend/"real" imap servers should not be on the same host (or the same dovecot instance) to
avoid proxying loops.
Is it still the case with the latest 2.1 stable release ? Is there a plan to be
able to run director and real server on the same host, thus requiring only 2
hosts instead of 4 to have

auth-deny : from file to LDAP
Hello Timo,
I want to deny access to some users. For now I'm doing it using 2 passdb's and listing users in a text file.
!include auth-deny.conf.ext -> passwd-file driver
!include auth-ldap.conf.ext -> ldap driver
I want to do the same using only LDAP. I'm not quite sure how to do it :

Master user without pass=yes error
Hello Timo,
I just tried the master user feature with a very simple setup (Dovecot v2.2.15) :
!include auth-master.conf.ext -> passwd-file passdb
!include auth-ldap.conf.ext -> ldap passdb (userdb prefetched) without auth_bind=yes
without pass=yes I get this userdb lookup error :

Dovecot Log analysis
Hello,
Before writing them myself, I'd like to figure out if some tools exist (anvil ?
...) and how to use them to extract from dovecot logs things like who is doing
what and how hard or how fast in order to do some rate limiting. For instance,
I'd like to be able to identify, slow or block users who

Maidir layout : why and how ?
Hello Timo,
I've been using dovecot from many years now using Maildir mailbox format with
default layout (Maildir++, everthing in a single directory).
What would be the reason(s) to convert to Layout=fs ? I can only think of one :
to allow dots in mailbox names. And even in that case, I guess I still have the
option to use the litescape plugin.
Besides, how would one process to do the

Thanks for your answer. That's what I thought after my tests. This explains why

Auth processes/login processes count
Hello Timo,
I'm running dovecot-1.2.12/Maildir/LDAP-passdb/LDAP-prefetched-userdb and I'm
experiencing "random" latency (which even seem to make squirrelmail timeout
sometimes) at login without noticing particular load on the server.
LDAP backends are running fine as far as I know so I was investigating maybe
mistuned limits :
Dovecot is configured (for ~3000 users) with

Confused about permissions needed for shared mailbox
Hello,
let me re-state, hopefully in clearer terms, what I tried to described in a previous thread :
With dovecot-1.1.8/Maildir/LDAP pass/userdb (prefetch), I'm trying to set up a
Maildir ".box" shared in rw between 2 users in a "Public" namespace. I can't
get it to work unless I chmod 777 everything, which obiously is not what I
want.

Symlink shared mailboxes and system_user extra field

I'm trying to set up, as explained in the wiki, shared mailboxes with symlink.
I'm running dovecot-1.1.8 with LDAP pass/userdb. The Maildir layout goes like this :

Public namespace permissions documentation/questions
Hello Timo,
In my trials to setup a shared namespace with dovecot-1.1.8/LDAP passdb/userdb
(prefetch)/Maildir, I found out that :
1) ACL are mandatory (at least if the acl plugin is triggered in dovecot.conf)
Am I correct ?
I'm still not sure if we can do without ACL at all (only with unix permissions and system_user userdb extra field).
2) the system_user userdb extra field is

How exactly would translate the "passdb" userdb example which is in

custom userdb server, Exim, and proxying
Hi all,
We have Exim using Dovecot for authentication. Dovecot, in turn, consults a custom internal server that answers Dovecot?s userdb queries.
When IMAP connections arrive, for some users we want to forward those connections--without authentication--to an external IMAP server. For these users, we return ?proxy_maybe? and ?nopassword? in the authn response from our userdb server. This tells
