[Dovecot] Mail client kill imap-login process
by dovecot acc 20 Oct '07

20 Oct '07

Hi, In my env we have quite a number of old PC which are running windows95. I have installed the thunderbird and outlook97 with the right configuration to dovecot. Everytime I starts the mail client it shows the following, dovecot: Oct 09 10:56:45 Info: imap-login: Disconnected: rip=172.24.65.60, lip=172.24.66.24 only then it shows the login screen. After submit the password, it doesn't seems to login properly. If I use the Outlook Express, it runs ok on the same machine? I can send and read email. I trace the process using strace but it failed since the pid got killed everytime I starts that two mail client. In order to make sure my dovecot run correctly, I run all mail clients from XP and it works like charm. Can someone share with my what should I do next or how to debug further? Thanks.

[Dovecot] Disconnects in log
by Jackie Hunt 20 Oct '07

20 Oct '07

Hi all, I need some help interpreting the info I'm seeing in the dovecot logs. I have a user using Outlook who is having connectively problems. Below is a sample of what the Dovecot log is showing. Can anyone explain to me why multiple logins occur within a few seconds of each other? Also, as I understand it, the "Disconnected" messages mean the kernel told Dovecot the connection was closed. I'm trying to figure out why I'm seeing so many of these. And why they seem to occur shortly after a login. Thanks for any insight!

[Dovecot] verbose_proctitle for proxy processes?
by Onno Molenkamp 20 Oct '07

20 Oct '07

Hi, We're using Dovecot to proxy incoming POP3 and IMAP connections to the right server. We'd like to be able to see what connections are currently open on the proxy servers, without having the parse the log file. For normal mail processes it's possible to use verbose_proctitle for this purpose, but this setting doesn't work for proxy/login processes. Is it possible to do something similar for proxy processes? Even without displaying the username and IP address, it would be useful to be able to see the difference between normal (idle/active) login processes, and proxy processes. Onno

[Dovecot] Per-user quota (with local users)
by Maykel Moya 20 Oct '07

20 Oct '07

I'm migrating to LDAP mi local users, there is the auth section of my dovecot.conf -- auth default { mechanisms = plain socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = dovecot group = nusers } } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb pam { } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } userdb passwd { } user = root } -- The idea is to try to find the user in the directory and if it isn't found then fallback to a local user lookup. My quota configuration is -- plugin { quota = maildir:storage=10240:ignore=Trash } -- I have some users with particular quotas. With LDAP lookups, there is no problem, in those cases I simply put their particular quota values in their entries and pass it to dovecot via user_attrs. I wonder how to do the same for local users, I mean, to have the ability of specifying particular quotas for some local users. Another doubt is how to express to Dovecot that a user have no quota at all, could I use 0? Regards, maykel

[Dovecot] dovecot and imap session forwarding
by Omer Faruk SEN 20 Oct '07

20 Oct '07

Hi, I was trying to install a qmail-ldap cluster. I have successfully setup dovecot to authenticate against ldap directory. But what I need is to enable imap session forwarding for qmail-ldap. For example when a user connects to a imapserver if the real mailhost of this user is different than the one that is connected so session is forwarded to real mailhost. Normally we can do that with courirer imap using auth_imap binary that comes with qmail-ldap which handles session forwarding. I have done this but got error auth_executable = /var/qmail/bin/auth_imap . Obviously it won't work. But I am not sure where to put /var/qmail/bin/auth_imap http://www.qmail-ldap.info/dovecot.php and http://www.qmail-ldap.info/imap_courier.php page shows a bit information about where to put it. -- Best regards, Omer mailto:omer@faruk.net

[Dovecot] thunderbird and email duplication
by Alexander Banthien 20 Oct '07

20 Oct '07

Hi all, I have recently switched over to Dovecot from CourierIMAP trying for some speedup, which I did get. Installation went OK, so all seemed fine. But suddenly I realised, that incoming emails are replicating themselves. This seems only to happen when connected with Thunderbird. I am also using Squirrelmail and KMail as clients which don't seem to show the behaviour. It seems to happen only for mails received during a Thunderbird session. When I close TBird and reopen it, only newly received messages will show the funny behaviour. The emails are real file copies in the Maildir, I have checked that. Running Dovecot on Debian Etch: dovecot --version: 1.0.0 (this is Debian package 1:1.0.0-1~bpo.1 from backports. I have tried the main package from Debian aswell, same result) with qmail delivering the mails to a Maildir without Dovecot's LDA. Clients: Thunderbird 2.0.0.6 on WinXP over Wireless LAN (tried Thunderbird/Iceweasel on Debian aswell) Squirrelmail and KMail (both running on the same box as Dovecot) don't show that behaviour. Has anybody seen anything similar or have any advice on what to look for? I would like to stick with Dovecot but the way it is looking now, I find working with emails near impossible.

[Dovecot] how to deliver when username and email differ
by Cory Coager 20 Oct '07

20 Oct '07

I have an Active Directory virtual setup and am using LDA to deliver to local recipients. Today I found a big problem with my configuration and not sure if this is fixable. Some of the users have multiple email addresses and the %n variable for user doesn't match their actual username. So if I have realname "Joe Bob" with a username of "joe" and an email of "jbob(a)somewhere.com", deliver will try to deliver to "jbob" and this is wrong. Here is the relevant part of my ldap config: user_attrs = mail,postOfficeBox=home user_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) pass_attrs = mail,postOfficeBox=home pass_filter = (|(mail=%n@%d)(proxyAddresses=%n@%d)(sAMAccountName=%u)) Somehow I need to change the username from the LDAP lookup but it seems that the mail attribute does this already. If I switch the mail attribute with sAMAccountName the domain becomes NULL. Anyone know if this is fixable?

[Dovecot] Dovecot v1.0.3 -> Sieve "redirect" command returning Sendmail exit status 75
by Elisamuel Resto 20 Oct '07

20 Oct '07

Hello! My local setup here is Exim 4.68, DSPAM 3.8.0 and Dovecot 1.0.5. Entirely on MySQL tables for virtual hosts and authentication. Dovecot does the authentication for Exim. What I am having problems with, is a simple sieve script to redirect a message that matches the "X-DSPAM-Result" header as "Spam" to another email address. When this rule matches, deliver returns in the log (which is attached) that "Sendmail process terminated abnormally, exit status: 75" What would cause this, and how can I resolve it? Thanks. -- Elisamuel Resto <samuel(a)dragonboricua.net> ID: 0x18615F19 / FP: B66D 1C2A E8EE B922 1D9C D98F D2D5 FB61 1861 5F19

[Dovecot] Problem with bodystructure/partial fetch using 1.1*
by mikkel＠euro123.dk 20 Oct '07

20 Oct '07

Hi there I'm using dovecot-1.1b2/b3 with deliver. All information is stored in an SQL database and no errors related to this issue are written to the logs (actually I get no errors at all). I've run into at problem; FETCH BODYSTRUCTURE is broken after upgrading to dovecot 1.1b2 (same issue with 1.1b3). BODUSTRUCTURE only returns information from the first section (with incorrect content-type/disposition) and discards everything else. This problem is somehow related to deliver; IMAP returns the correct BODYSTRUCTURE for e-mails received before the upgrade, but an incorrect for ones received after the upgrade. This tells me that IMAP is working properly but somehow the MIME sections are being corrupted doing mail delivery (if I fetch the complete body nothing seems to be wrong). Also if I fetch a section something is not right - instead of just the section I get part of the Content-type header as well (but only half the header). Obviously this makes various webmail clients go somewhat crazy while Outlook/Thunderbirds dont mind (since they fetch the complete body and do the MIME parsing themselves). These are my compile options (GCC 3.4.3 on Solaris 10): CPPFLAGS=-I/opt/pkgsrc/pkg/include/mysql LDFLAGS=-L/opt/pkgsrc/pkg/lib/mysql ./configure --prefix=/opt/freeware/dovecot-1.1b2 --with-pop3d --with-deliver --with-mysql --with-prefetch-userdb --with-sql --with-gnu-ld --with-ssl=no --enable-header-install make; make install Everything else works flawlessly.

[Dovecot] In 1.1.beta3, COPY cmd results in msg with Content-length: 0 and no text
by Eric Weaver 20 Oct '07

20 Oct '07

I run Thunderbird with message filters that sort mail into other folders, and this has killed me for the day. COPY commands (and I have verified this with a manual test) result in the message headers coming out correct but the body totally missing. Is this a known issue being addressed? Thanks Eric Weaver
