by Davide 12 Apr '13

12 Apr '13

I have a little problem in my configuration (vpopmail + qmail + dovecot 2.1.12 with LDA) my .qmail-default is this | /var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda -d $EXT@$USER -e | /home/vpopmail/bin/vdelivermail '' bounce-no-mailbox I receive al mails to postmaster for non-existent users (all my users are virtual and live under group 89 vpopmail) and this is ok but all mails for quota-full users dosen't If i remove the vdelivermail part in .qmail-default i receive bounce for quota-full but not for non-existent users.

Also make certain that you don't have anything in your > hosts.allow file that would override the hosts.deny entry. I was using dovecot, until you convinced me to do otherwise. Putting pop3 in /etc/hosts.deny with the associated ip seems to work, like so: pop3: 166.84.1.2 or imap imap: 166.84.1.2 (are there any challenges to this?) Given that services such sendmail and sshd respond to sshd: xxx.xxx.xxx.xxx sendmail: xxx.xxx.xxx.xxx I thought that it should be dovecot: xxx.xxx.xxx.xxx As a suggestion, can dovecot binaries for distributions such as CentOS and Fedora be compiled with tcp wrappers by default? > - Richard Much thanks.

[Dovecot] Questions about the upcoming Object Storage Plugin for 2.2
by Charles Marcus 11 Apr '13

11 Apr '13

Hi Timo, I'm curious and have questions about the new Object Storage Plugin (OSP), and how it can be leveraged by an SMB like us. First, am I reading this right where it could be used as a kind of 'live/realtime backup' solution, where everything is stored *both* locally and in the cloud, with two-way syncing, ie, so local users could access the local server for faster access, and when outside the office, they'd access the cloud based storage and any changes made there are sync'd back to the local server? Or is it intended to be more as an alternative storage for storing older emails in a separate namespace? Or both/either? Second, is SIS fully supported by the OSP? Third - I'm a little confused by the Amazon S3 pricing page, especially on how to try to estimate the costs for usage (bandwidth, etc)... do you have any idea how to go about estimating that? Is there some kind of process we could use on our existing server to measure it over a given period of time that would give us an estimate of what to expect if we decided to switch over? Last - have you established pricing for the OSP? Will it be per user, or per MB/GB, per month (or per year), or just a one-time cost? And/or will you include/bundle it with any/all of your support tiers? Sorry if I'm jumping the gun here... Thanks, really looking forward to the 2.2 release! -- Best regards, Charles

Sorry for top posting, but I have no additional info on this. BTW I need to refresh the question as I have tried squat, and I'm biting the dust with the already known problems ( "Corrupted squat uidlist file" or "Panic: file squat-trie.c:" ). Is there some pointer on where/how to find assist on fts-lucene to keep on analisys for this problem on sparc ? T.I.A.

Greetings, I am looking to implement tcp wrappers with dovecot; I am using the following two links as guides to configuration: http://blog.acsystem.sk/linux/brute-force-attack-dovecot-imap-server-blocki… http://wiki2.dovecot.org/LoginProcess (you need to go to the very bottom) I'm concerned in making the configuration correctly. If you set login_access_sockets = tcpwrap in /etc/dovecot/dovecot.conf Then everything accessing ports controlled by dovecot (and open by iptables) is blocked. So my question relates to the second part of the configuration examples in the links above: service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } Where does this code get placed (in dovecot.conf or in one of the files in /etc/dovecot/conf.d)? And regarding $default_login_user, it appears in a comment line in /etc/dovecot/conf.d/10-master.conf Should that line be uncommented? Much thanks.

[Dovecot] [PATCHES] NetBSD support, authentication buffer size
by Emmanuel Dreyfus 11 Apr '13

11 Apr '13

Hi Here are a few unintegrated patches, just tested against 2.2rc7: 1) NetBSD's getmntinfo uses struct statvfs while other BSD use struct statfs http://ftp.espci.fr/shadow/manu/patch-ak 2) NetBSD 5.x net_getunixcred() support. Build on NetBSD, but not tested (I am testing on NetBSD 6.0): http://ftp.espci.fr/shadow/manu/patch-src_lib_net.c 3) Increase authentication buffer size so that it can cope with unusual authentication scheme. This patch was integrated in dovecot-1.x but did not make its way in dovecot-2.x http://ftp.espci.fr/shadow/manu/patch-src_lib-master_master-auth.h -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] Easy way to make all mailboxes of a user read-only
by Stephan von Krawczynski 11 Apr '13

11 Apr '13

Hello all, I try to configure dovecot to make all imap accesses read-only for a certain user. I thought this would be possible by creating a global acl file (here "global-acl") like: user=<username> lr and plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 } But that seems to be ignored. What is wrong with this idea, the docs are not really clear about a single acl file with global settings. -- Regards, Stephan

[Dovecot] v2.2.rc7 released
by Timo Sirainen 11 Apr '13

11 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz.sig OK, still not quite v2.2.0, but now it's definitely very close. :) * checkpasword: AUTH_PASSWORD environment is no longer set. * Running dsync no longer triggers quota warnings. + dsync: Commit large transactions every 100 new messages, so if a large sync crashes it doesn't have to be restarted from the beginning. - replicator: doveadm commands and user list export may have skipped some users. - Various fixes to mailbox_list_index=yes

[Dovecot] Dovecot distribution configuration files source
by Dave Gattis 11 Apr '13

11 Apr '13

Where can I find unaltered distribution config files (/etc/dovecot/ and /etc/dovecot/config.d/) for Dovecot 2.1.7? I upgraded from version 1 and had to butcher them to get it working. Now that I understand it better, I'd like to do it right. -- Dave

[Dovecot] My old email is not stored
by HylkeB 11 Apr '13

11 Apr '13

Hi, Im have not much experience with dovecot, postfix or debian, which i am using for my email server. But the thing is, everything worked just fine, until I found out that old emails were missing, only emails of a few months old exist on my server. I have no idea if this is a setting in dovecot, postfix or debian, or that something weird happened. But my question is, is there a setting in either dovecot, postfix or debian that i should check that could cause this behaviour, and if so, how do i check that? (opening and checking a conf file for example, or executing some commands in PuTTy). And if this is somehow default behaviour that cannot be changed, is there some other way to store all emails ever entered my inbox? Sincerely, Hylke Bron -- View this message in context: http://dovecot.2317879.n4.nabble.com/My-old-email-is-not-stored-tp41478.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Proxying, pertinent values and features, SNI
by Christian Balzer 11 Apr '13

11 Apr '13

Hello, I'm looking into deploying dovecot as a proxy, currently using perdition. Have been using dovecot on the actual servers for years, nearly a decade. So far just 1.x, but for the proxy it will have to be 2.x (2.1.7 is the current Debian version), as the trigger for this change is the need to support multiple SSL certificates. All that happens on the proxy seems to be handled by the login processes, so that is why we're not seeing anything useful in the process titles or with doveadm, right? And from past comments by Timo I guess that adding such functionality isn't on his to-do list at all. A configurable capabilities string for POP would be quite welcome, but at least nothing is different between the 1.x backends and the 2.x proxy in that protocol. Speaking of 1.x versus 2.x, the feature to pass on the remote IP from the proxy to the backend is a 2.x thing only, correct? So I suppose any parameters really affecting this setup are default_process_limit and default_client_limit as well as the settings in service-imap-login and service pop-login. In particular mail_max_userip_connections never is looked at on the proxy as this check happens in the respective protocol AFTER login, rite? I presume to best support all(?) clients out there is to have "local_name" sections for SNI first and then "local" sections for IP address based certs. It is my understanding that SNI needs to be requested by the client, so aside from client bugs (nah, those don't exist ^o^) every client should get an appropriate response for TLS. Has anybody done a setup like that already? Regards, Christian -- Christian Balzer Network/Systems Engineer chibi(a)gol.com Global OnLine Japan/Fusion Communications http://www.gol.com/

[Dovecot] [PATCH proposal] make dsync preserve pop3_uidl_format
by Mark Zealey 11 Apr '13

11 Apr '13

Hi there, I ran into an issue yesterday (dovecot 2.0) whereby when we dsync messages from a local machine (sdbox) to a remote (Maildir) which have different pop3_uidl_formats configured, the uidl format is not preserved. There doesn't seem to be any way to force this in the code, although I suspect that Maildir sources with saved pop3 uidls would pass them correctly. Attached is a rough patch against 2.0.21 dsync which will generate the uidls on the client before passing them over to the destination. This only works for %u and %v currently, also because dsync doesn't read the whole config file you need to specify -o pop3_uidl_format=... to dsync. Mark

[Dovecot] Postfix/Dovecot/lmtp with virtual and local users
by David Obando 11 Apr '13

11 Apr '13

Hi all, I'm about to change my Debian mailserver setup from Postfix/dovecot1/procmail to Postfix/dovecot2/sieve with lmtp enabled. After enabling lmtp the virtual users can receive e-mails but not the local users: Mar 21 14:21:40 orange postfix/lmtp[4119]: DE62226216: to=<user(a)orange.domain.de>, relay=orange.domain.de[private/dovecot-lmtp], delay=7627, delays=7627/0/0/0.02, dsn=5.1.1, status=bounced (host orange.domain.de[private/dovecot-lmtp] said: 550 5.1.1 <user(a)orange.domain.de> User doesn't exist: user(a)orange.domain.de (in reply to RCPT TO command)) In 10-auth.conf I have the setting "auth_username_format = %Lu". When changing it to "auth_username_format = %n" the local users can be found but not the virtual users anymore. Is there a way to define "if <user> is local then auth_username_format = %n else auth_username_format = %Lu"?

[Dovecot] Pigeonhole 0.3.4: Warning: sieve: encountered corrupt binary: re-compiling script
by Daniel Piddock 10 Apr '13

10 Apr '13

Hi all, Upgraded to Dovecot 2.1.16 and Pigeonhole 0.3.4 yesterday. We use lmtp and sieve. I've now started to see in the logs the following entries: >Warning: Jz6kNv8AY1FdfQAAVMeomg: sieve: encountered corrupt binary: re-compiling script [script path] The script then appears to run correctly and the message gets stored where ever it should be. This only appears to be happening for a few users and although it happens on the majority of their messages it doesn't happen for every single one. What's the best way to start debugging? Thank, Dan

[Dovecot] thunderbird detach attachment
by mourik jan heupink 10 Apr '13

10 Apr '13

Hi all, Thunderbird has an option to detach attachments from (for example) sent items. I've tried it, and it does not work, and also in the dovecot logs I don't see anything interesting meanwhile. Before looking deeper into this: Does anyone here know if this option is known to work, or not? We're running dovecot 2.1.7 on debian wheezy. Removing unwanted attachments is a nice way to keep mail archives smaller... Thanks, MJ

[Dovecot] How to see folders/subfolders/emails through imap
by Stephan von Krawczynski 10 Apr '13

10 Apr '13

Hello all, I am trying to do something very simple - at least thats what I thought. I have some fs, it contains folders and subfolders with email files ordered like maildir. Now I try to set up dovecot on top simply to let some imap account watch these email files. But I cannot see any folders at all. I can create new folders and see them, but I cannot create subfolders as subdirs like "folder/subfolder". Instead I get "folder.subfolder" dirs on the fs. I tried to set the separator to "/", but that does not help at all. Is there some easy way to configure dovecot to display: <somedir>/<folder1>/<subfolder1>/new/files... <subfolder2>/new/files... <subfolder3>/new/files... according to fs layout on some imap-client (like thunderbird)? -- Regards, Stephan

You probably want to compile in tcp_wrapper support and handle it that way http://wiki2.dovecot.org/LoginProcess You might also hook into a the post-login script if you need some bizarre logic to determine whether to allow a login or not, but this is later in the session setup rather than block-on-sight like a firewall. http://wiki2.dovecot.org/PostLoginScripting Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] How to exec /usr/libexec/dovecot/imap with specific maildir location
by David Woodhouse 09 Apr '13

09 Apr '13

Once upon a time I could configure my mailer to access my historical archives by running something like ssh $mailserver MAIL=maildir:~/Maildir-archive dovecot --exec-mail imap I need to run /usr/libexec/dovecot/imap manually now, and I've fixed that a while ago for my normal email access. But I've just had cause to go back to my archives for the first time in a while... and realised that I don't know how to make it work any more. When invoking /usr/libexec/dovecot/imap, is there an environment variable or command line option which can set the mail location? -- dwmw2

[Dovecot] Any simple way to block logins by IP address?
by Steve Campbell 09 Apr '13

09 Apr '13

Does Dovecot have a facility to block pop3 and imap logins by IP address. I usually do this by putting the IPs in my border firewall, but it's in transition currently to a new one, and I'd like to end connection fairly fast. If it matters, I'm using 2.0.9. Thanks steve campbell

[Dovecot] Received date on emails is wrong after file copying
by maia＠weiser.dk 09 Apr '13

09 Apr '13

Hi, I have installed a new mail server where I'm migrating from Courier to Dovecot. I have made a mistake when I was copying over the emails so the date/time mark on them is updated. So all my mails are now from the copy date/time and not the real receive time. I have tried to copy the emails over again, so they get the right date/time on the file level. And when I look at a single email in details in SquirrelMail it has now the right date/time, but when I look at the overview of a folder it still have the copy date/time on them. Is there any way to get the date/time in the overview updated, maybe delete some index files or force it to re-index? I'm not even sure that the problem is in Dovecot. But I'm sure You can help me here. Best Regards, Kim Johansen
