[Dovecot] Authentication using multiple password schemes
by hever＠web.de 25 Feb '08

25 Feb '08

Hi there, I tried to patch the actual Dovecot 1.1 rc1 with the http://dovecot.org/patches/1.1/auth-multi-password.diff. The patch doesn't work for this version and I don't want to get an old version. Is this patch perhaps in the 1.1 rc1version included? I'm not sure because I don't really know how it's to use. I thought about returning some password fields from a database. If not could someone provide a working patch ? I need this patch because I'm going to provide NTLM and CRAM-MD5 POP/IMAP authentication because Outlook doesn't support CRAM-MD5 as non-plaintext authentication and I don't want store plaintext passwords. _______________________________________________________________________ Jetzt neu!

[Dovecot] mbox with two storage locations
by Bill Pitz 25 Feb '08

25 Feb '08

Hello, I'm trying to migrate a legacy system to Dovecot in which I need to support mbox format storage with the following parameters: Inbox is in: /var/spool/mail/%u Additional mail folders are stored in: /var/spool/mail2/%u (i.e. Spam, Sent, Trash, Drafts, etc.) /var/spool/mail and /var/spool/mail2 are configured with the same permissions. (Read/write/execute user root, Read/write/execute group mail). I've added mail as an additional group in the Dovecot configuration. # dovecot --version 1.0.10 # 1.0.10: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login first_valid_uid: 100 mail_extra_groups: mail mail_location: mbox:/var/spool/mail2/%u:INBOX=/var/spool/mail/%u:INDEX=MEMORY auth default: passdb: driver: pam userdb: driver: passwd The problem is what when I run this configuration, I am not able to see any of the contents of /var/spool/mail2. I ran around with this problem for a while and ultimately found that the following fixes it: cp -Rpfd /var/spool/mail2 /home Change Dovecot to use /home/mail2/%u instead: # 1.0.10: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login first_valid_uid: 100 mail_extra_groups: mail mail_location: mbox:/home/mail2/%u:INBOX=/var/spool/mail/%u:INDEX=MEMORY auth default: passdb: driver: pam userdb: driver: passwd Further investigation revealed that no path outside of /home would work for the storage of the mbox directory. Any ideas? Everything seems to work great except for this one (pretty major) issue. Also, /home, /var, and / are separate filesystems. I'm not sure if that's playing into this or not (doesn't seem like it, since it seems to have no issue storing INBOX in /var/spool/mail). Thanks, -Bill

[Dovecot] 1.1rc1: Maximum number of mail processes exceeded
by Ralf Hildebrandt 25 Feb '08

25 Feb '08

I'm getting "Maximum number of mail processes exceeded" messages when 512 imap Processes are active. Dovecot reports: Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1712). Either grow the limit or change login_max_processes_count and max_mail_processes settings But in my /var/service/dovecot/run script I use: #!/bin/sh mkdir /var/core chmod 1777 /var/core echo /var/core/%p > /proc/sys/kernel/core_pattern ulimit -n unlimited ulimit -c unlimited /usr/local/sbin/dovecot -F So how can I raise the filedescriptor limit above 1024 (linux-2.6.24.2, Debian)? -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) snickebo(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de StGB SS328 Absatz 2.3: Mit Freiheitsstrafe bis zu f�nf Jahren oder mit Geldstrafe wird bestraft, wer eine nukleare Explosion verursacht

Re: [Dovecot] Dovecot Sieve scalability

Hi, What exactly do you mean with "deliver preps the index"? Dovecot itself preps/creates/alters the index, when retrieving mail; right? Or are you (probably) saying this is one more benefit of using 'deliver'. Anyone know of any 'deliver'/(dovecot) stresstests with regards to forking and threading of the deliver binary?

More so for the average disorganized INBOX in my only folder customers. Sieve makes a lot of things smoother for users, the customer. Especially if they expect server side rules. Obviously the rules that drop each message into a Backups or forward messages to other hosts take up what they take up. My sievec files have ancient mtimes.

[Dovecot] Dovecot Sieve scalability
by Jan van den Berg 25 Feb '08

25 Feb '08

Hi, I just finished setting up a functional design with Dovecot+Sieve and it works like a charm. However I'm having serious doubts about the scalability of this. Here is part of a discussion we're having here: About Dovecot+Sieve. What happens here is that your MTA is configured to pass _all_ email to Dovecot which is configured as a LDA. In practice this means this in the Exim config: command = /usr/local/dovecot/libexec/dovecot/deliver So you call on a single binary "deliver". This binary then looks for a .dovecot.sieve file in the user maildir, _compiles_ it to .dovecot.sievec file, and than drops the mail according to the rules. Calling a single binary: that's isn't threaded, doesn't fork, and that has to compile a file (everytime?) it's called isn't scalable. Multiply this with 100 mails(calls) per second and this is bound for problems. The Dovecot/Sieve implementation is functional but not very elegant or robust. But this can be explained because Dovecot is build for _retrieving_ mail (imap/pop) and _not_ delivering mail. Any thoughts on this? Are there people out there with large Dovecot+Sieve implementations (100k+ users). Are there benchmarks available; how well does it perform under heavy load (mails/sec)? Cheers, Jan

[Dovecot] Update from 1.0.10 -> 1.1rc1 Inverted quota warning values?
by Ralf Hildebrandt 23 Feb '08

23 Feb '08

I used 1.0.10 with the quota-rewrite patch for v1.0. With that, I configured: quota_warning = storage=10%% /usr/local/scripts/quota-warning 90 quota_warning2 = storage=5%% /usr/local/scripts/quota-warning 95 quota_warning3 = storage=1%% /usr/local/scripts/quota-warning 99 with 1.1, the logic for the quota_warning entries changed (http://wiki.dovecot.org/Quota/New) quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 Is that really correct (I admit, the new way is more intuitive to me). -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) snickebo(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de "Java is, in many ways, C++--." - Michael Feldman.

[Dovecot] Maildir Subsystems
by Aaron Wiebe 23 Feb '08

23 Feb '08

Greetings - new to the list, so apologies of I'm asking questions that have been brought up before. I work for a large email provider, currently using qmail, vpopmail and courier-imap. We tend to make fairly regular customizations of the software, and if you folks have any knowledge of courier's code layout, you probably can understand why we hate working on it. Anyway, I am looking at the possibility of migrating to dovecot, after a quick review of the code layout. It is MUCH nicer to read. But I have a few specific questions: 1. We customize our maildir system fairly heavily, and I'm wondering where the maildir code is located. Specifically, anywhere the app actually does work on disk related to folders, mail content and quotas. While I have reviewed the code in brief, I thought it would be easier to poke this list to get pointed in the right direction. 2. Courier works quite well over NFS for us, and I'm curious why your documentation covers NFS more specifically. What aspects of the filesystem are normally used that don't translate easily to work over NFS? Do you use stuff like inotify or atimes? 3. If anyone has any suggestions on how to migrate tens of thousands of imap users from courier to dovecot in a few hour window, I'd like to hear them :) Thanks, Aaron Wiebe

[Dovecot] Put existing mails (in Maildir) through sieve filter?
by Andreas Ntaflos 22 Feb '08

22 Feb '08

Hello list, the scenario: A user has about 30k mails in his Maildir (all in INBOX) and needs to apply filtering. Provided he writes a working .dovecot.sieve script, is there a way to put all those already delivered mails through Dovecot's LDA and thus have the sieve filter rules applied? Or is there any other way to apply sieve rules to already delivered mails? TIA Andreas -- Andreas "daff" Ntaflos Vienna, Austria GPG Fingerprint: 6234 2E8E 5C81 C6CB E5EC 7E65 397C E2A8 090C A9B4

[Dovecot] Postfix on one host/Dovecot (mailboxes) on another - How?
by k bah 22 Feb '08

22 Feb '08

Hi, I'm using Dovecot 1.0.5 on OpenSUSE 10.3. I run postfix/amavis/clamav on one host, postfix uses LDAP to identify whether or not users exist. On this same machine I was running dovecot, so I used dovecot LDA on Postfix master.cf (as mentioned on http://heinous.org/wiki/Virtual_Domains,_Postfix,_Dovecot_LDA,_and_LDAP#Pos…) Now I want to run Dovecot on another machine, how should I configure postfix on that first machine? first machine: the domain my users know/use; webmail; postfix/amavis/clamav; mx record for domain all users have mail addresses; imapproxy (pointing to the second machine, where the imap server sits). second machine: just dovecot and user's mailboxes. (I need to keep this machine doing only this task, because of the load) Is there a way to do that just by adding a mailbox_transport to the first machine's postfix? thanks = Mobile (Volumetric) Concrete Mixers The innovative leader in the mobile concrete mixer industry.

[Dovecot] Deliver - Virtual users
by Tobias Balle-Petersen 22 Feb '08

22 Feb '08

Hello... I have dovecot 1.0.10 running with users in an LDAP database. Things are working as they should with IMAP. However, I can't seem to make deliver w. postfix work they way I want. My problems are: Mail to users who do not exist in LDAP or locally are accepted and mailfolders are created. I want mail to users that do not exist in LDAP or locally to be rejected. Mail is delivered to users even though they are over quota. Below I have included a bit of my log. This is what I see when sending a mail to an existing user. I don't understand the part that says: dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): lookup In my database users are stored as usernames without domains. Deliver seems to lookup the name with domain? The lookup ends with "unknown user". Then I wonder, why is the mail delivered if the user is unknown? I have included the "protocol lda" part from my dovecot.conf and the result of "dovecot -n". Can someone help me get this sorted out?

This way I'm the only one to see your post and I'm not sure that I can help. Also other users may benefit from your experience if it's available online. When you post to doveco(a)dovecot.org a copy is sent to me anyway. I'm not sure that I can help. I think you should check your permissions on the folder. And I think you should try with: fileinto "Junk"; Instead of: fileinto ".Junk"; (without the preceding dot that is) The preceding dot will automatically be added to the folder name by dovecot so it may create confusion if you use it too. Dovecot always uses the dot-prefix on folder names in the file system but this isn't really part of the IMAP/Sieve folder name that you wanna use. Regards, Mikkel

[Dovecot] verbose IMAP logging
by Robert Chien 22 Feb '08

22 Feb '08

Hi, Is there a way to enable telemetry or debug-level logging in Dovecot IMAP, to see the exact IMAP command issued by the client and server? E.g. to confirm if a certain MUA is indeed using IMAP IDLE, or if it's doing LIST or LSUB. The IMAP connection is made over TLS/SSL, so tcpdump won't work. Thanks, Robert

[Dovecot] Dovecot on CentOS5 - (login) returned error 127
by Tim Alberts 22 Feb '08

22 Feb '08

Running CentOS Linux 5 with sendmail-procmail putting email in /var/spool/mail. I'm running pop3 only with the servers configured to authenticate with ldap (which is configured and running OK). I do have this same configuration on an older FC6 box and it works fine. I'm thinking I just need to upgrade dovecot given all the nss_ldap problems it has had, but I hate not using RPM packages and CentOS does not have upgraded packages. Hardware is Dell PowerEdge 1900 (64bit) with 2G RAM. Hopefully I'm doing something stupid and there's an easy fix for the packages and configuration I have. I'm seeing the following in the /var/log/maillog when I run dovecot. When I log in via telnet, I get the connection, but it never responds when I enter a user.

[Dovecot] Dovecot User Script?
by David White 21 Feb '08

21 Feb '08

I am new to Dovecot. I have been using Postfix as a mail relay to our Exchange box and have been happy with the setup. The Linux box also runs Apache and VSFTPD for our WWW and FTP services. However, we are now starting up a new smaller domain. I am grabbed a spare box and have setup Fedora 7 on the machine. I am can handle apache, vsftpd, and postfix alright, but I am not familiar with dovecot. I need a simple setup of about 15-20 users. Instead of setting up each user through the terminal is there a PHP script that anyone would recommend? A setup of virtual users in mysql is preferred, since I already have that installed. I found a HOWTO on Howtoforge with ISPconfig, but it did not setup Dovecot. They forgot that setup. Any suggestions would be useful. Thanks! David White dwhite(a)fddisystems.com

[Dovecot] Dovecot imap bad quota report
by Carlos Acedo 21 Feb '08

21 Feb '08

Hello, I have dovecot mail server on a Debian etch: dovecot-common 1.0.10-1~bpo40+1 dovecot-imapd 1.0.10-1~bpo40+1 dovecot-pop3d 1.0.10-1~bpo40+1 It is configured with the quota plugins: protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle } plugin { quota = fs } The problem is that I always get used space but not the limit, and the limit is not the same for all the users, I have tried from thunderbird and horde IMP from another server. Why is not reporting the quota limit? Oh, I'm using mbox for mail storage and the quota programm to set quotas Thank you, Carlos -- To UNSUBSCRIBE, email to debian-isp-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

[Dovecot] corrupted index?
by Gary Funck 21 Feb '08

21 Feb '08

We're seeing the following sporadically in the log file (single line broken into separate lines for readability): Corrupted index cache file /home/user/mail/.index/.imap/INBOX/dovecot.index.cache: invalid record size We're running dovecot-1.0.7-2.fc8. The imap directory is in the user's NFS-mounted /home directory, but doveot is running on the same host as the /home filesystem. There's plenty of disk space and no other significant system problems. The mail index directory we rm'd a week/so ago, so doveoct has had the opportunity to rebuild it. Any ideas on what might be causing this? Is this issue anything to worry about? thanks.
