[Dovecot] Permission denied creating inbox file in /var/mail
by Steve Ochani 01 Aug '08

01 Aug '08

Hello all, I'm using dovecot version 1.07 on CentoOS 5 (clone of RHEL 5). When there is no existing mbox file for a user in /var/mail I get the following error: --------------- Jul 31 16:32:32 newnewton dovecot: imap-login: Login: user=<testm2>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): open(/var/mail/testm2, O_CREAT) failed: Permission denied Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): access() failed with mbox file /var/mail/testm2: No such file or directory Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): stat() failed with mbox file /var/mail/testm2: No such file or directory Jul 31 16:32:32 newnewton dovecot: IMAP(testm2): Connection closed ---------------- My persimmons on /var/mail (which is a symlink to /var/spool/mail) : drwxrwxr-x 2 root mail 4096 Jul 31 16:32 mail I have tried adding the mail group as mail_privileged_group, the output of dovecot -n : -------------------- # 1.0.7: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:~/IMAPmail:INBOX=/var/mail/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd -------------------- Here is the permission on /etc/dovecot.conf -rw-r--r-- 1 root root 42833 Jul 31 15:30 /etc/dovecot.conf I've searched google and the mailing list archive and tried the couple of things commonly suggested. As for a test I changed perms on /var/spool/mail to 777 and then dovecot made the inbox file. The file ended up being owned by the user and the group owner was the group that the user belongs to, not mail. When I create new users using useradd there is a 0 byte file created in /var/mail for the user but I use scripts to create student accounts every semester (about 10,000) so I'm trying to avoid having to add more things that the script will have to create. Any help is greatly appreciated. Thanks -Steve O.

[Dovecot] dovecot.sieve file location?
by kbajwa 01 Aug '08

01 Aug '08

CentOS 5.2 Postfix-2.3.3 Dovecot-1.1.1 Dovecot.Sieve-1.1.5 I have setup with: home_mailbox = Maildir/ (/etc/postfix/main.cf) & mail-location = maildir:~/Maildir (/etc/dovecot.conf) I have created a 'test' user to test Sieve 'Vacation' setup. My questions are: 1. Which folder '.dovecot.sieve' script is copied into? Is it 'home/test' -or- 'home/test/Maildir' or someplace else? 2. '.dovecot.sieve' script parameter ":days 1" means that the reply is sent once a day. Is it possible to send the reply 'immediately'? Kirti

[Dovecot] Dovecot load balancing
by Thomas Hummel 01 Aug '08

01 Aug '08

Hello, I'd like to figure out how to set up a site running dovecot on multiple computers for load balancing reasons. I'm currently running dovecot-1.0.14 on a 8GB RAM, 2 quad-core 2.66Ghz Xeon single server which runs FreeBSD 6.2-STABLE SMP. . the mailbox format was mbox and I successfully migrated to Maildir only . mailboxes are on an NFS NetApp server, attribute caching is off . indexes are locally stored . the number of users is around 2500, some of them having huge mailboxes (~ 1 or 2 GB) . a large amount of users is using IMAP but there are also many POP3 users . the passdb/userdb is openLDAP . for now, I neither use namespaces, nor quotas nor deliver, nor any plugin, but I plan to use namespaces and ACL to implement shared mailboxes. The same machine is running postfix-2.4.6 with amavisd-new-2.5.4 (no spamassassin) and clamav-0.93.1. I'm using procmail-3.22 as the LDA. I installed dovecot-1.1.2 on non-standard ports for test and plan to switch to it as I read on this list it performs better, load wise. This setup (1.0.14) works great except that, compared to the time mailboxes were in mbox format, the load average (as shown by 'top') goes higher from a significant amout on a regular basis and sometimes goes over the top. On "normal" circumstances, the number of processes is around 1400 and the load oscillates between 1 to 10 and 30 to 60. Most of the time, I'd say the load average is around 20. Every friday a message (no attachement, decent size) is sent to all users : in such circumstances (but only sometimes, not every time : let's say half the time such a message is sent), the load goes so high that I have to stop dovecot to let procmail deliver the message or even reboot the machine. Sometimes, the load climbs up to something like 150, then goes back to the 'normal' case described above. I know multi-master replication is on the roadmap. I know some dovecot sites use in the meantime several dovecot servers. I'd like to know how those sites do the load balancing, the main problem beeing to be able to direct each user to the same dovecot server each time as stated in the Wiki (http://wiki.dovecot.org/NFS) I don't think that DNS round robin would do the trick because some UA (for instance Thunderbird) often open up to 5 connexions for the same user, unless maybe such UA makes a single 'gethostbyname()', thus connecting 5 times to the same physical server ? What are the options to achieve such a setup ? Any successful experiences ? Thank you -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] One LDAP attribute for many variables
by Juan Asensio Sánchez 31 Jul '08

31 Jul '08

Hi Using Dovecot 1.1.2 with LDAP. If i have this: user_attrs = uid=home=/var/vmail/%$,mailuserquota=quota_rule=*:storage=%$,=mail=maildir:/var/vmail/%n/Maildir OK. But if i have this: user_attrs = uid=home=/var/vmail/%$,mailuserquota=quota_rule=*:storage=%$,uid=mail=maildir:/var/vmail/%$/Maildir I get this error: deliver(usuario1): Jul 25 12:59:08 Error: Per-user script path is unknown. See http://wiki.dovecot.org/LDA/Sieve#location The only difference is that I use the uid LDAP attribute twice. Why does this happen?

[Dovecot] Seen flag in maildir filename not being respected
by Eduardo M KALINOWSKI 31 Jul '08

31 Jul '08

Hi, I'm using dovecot 1.1.2 (but I've noticed this since 1.1.1 which I was using until yesterday). It seems dovecot is ignoring the "S" flag in Maildir filenames, and is relying only in its Index Files to determine if a message has been read or not. I say that because if I delete the dovecot.index.* files for a mail folder, all the mails in there appear as unread. Also, I've tried accessing the maildir directly (using heirloom-mailx, but mutt should have done, too) and reading a new message. The file name was changed to add a "S" to the end, but this message was still marked as "unread" when the mail folder was accessed via IMAP. The flags R, F and T are correctly read from the filename if no index is present. I haven't tested the other flags. I'm using dovecot's deliver, and it creates filenames such as "1217450416.M77457P5201.mail.kalinowski.com.br,S=1377,W=1411:2,S", that is, perfectly fine. dovecot -n: # 1.1.2: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/server.pem ssl_key_file: /etc/ssl/private/server.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/INBOX:INDEX=/home/vmail/%d/%n/dovecotidx mail_plugins: quota imap_quota zlib auth default: mechanisms: plain login cram-md5 passdb: driver: passwd-file args: username_format=%n /home/vmail/%d/db/passwd passdb: driver: pam userdb: driver: static args: uid=104 gid=8 home=/home/vmail/%d/%n userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: mail plugin: quota: maildir quota_rule: ?:storage=0 quota_rule2: Trash:ignore quota_rule3: Spam:ignore quota_rule4: Spam.Errado:ignore sieve: /home/vmail/%d/db/sieves/%n.sieve

[Dovecot] wrong permission
by Cor Bosman 31 Jul '08

31 Jul '08

Im still finding a number of control directories that have the wrong permission: Jun 26 00:02:34 userimap13.xs4all.nl dovecot: IMAP(xxx): file_dotlock_create(/var/spool/mail/dovecot-control/g/gl/xxx/INBOX/.Apple Mail To Do/dovecot-uidlist) failed: Permission denied userimap1# ls -al "/var/spool/mail/dovecot-control/g/gl/xxx/INBOX/.Apple Mail To Do" total 8 drw------- 2 xxx user 4096 May 12 23:43 . drwx------ 7 xxx user 4096 May 12 23:43 .. This folder was created May 12, well after us starting to use 1.1RC versions. I currently fixed a few hundred of these (out of millions of folders), and whats interesting is that a very large percentage of those (1/3th) is the folder "Apple Mail To Do", created by Mail.App I think. Obviously that same folder is no where near 1/3th of our total folder number, so thats a bit strange. I really doubt this is some local setting issue, because then id see much more of those. Right now it's a tiny fraction of our total folder amount, which leads me to believe it's some weird edge case in the dovecot code. Anyone have any ideas? Cor

[Dovecot] dovecot-imap displays empty domainalias mailboxen
by Kacper Wysocki 31 Jul '08

31 Jul '08

Hi folks, I'm using dovecot 1.0.13 as the IMAPS frontend for a vpopmail/qmail virtual domain setup. Dovecot is set up as follows: passdb vpopmail{ } userdb vpopmail{ } I've added a domain alias for the main domain with vaddaliasdomain and email to post@aliasdomain is delivered to post@maindomain and can be checked with pop. However, when I try to check IMAP through the account post@aliasdomain I am confronted with an empty mailbox. If I log in using post@maindomain I get the expected contents. Why can't my users log in using user@aliasdomain to check their emails? Regards, Kacper Wysocki -- http://kacper.doesntexist.org http://windows.dontexist.net There is symmetry in chaos, and chaos in excessive order. Though you may see heaven or hell, remember that it is your mind which creates them. Avoid grasping the one or fleeing the other.

These (in .../Maildir/cur) are your problem - someone created a Maildir underneath Maildir/cur, and dovecot or some other software considered the three directories messages, and goofed up. Check your delivery recipes so that none deliver to .../Maildir/, if you find any, adjust them deliver to .../Maildir/ instead. I'd suggest to: cd /home/matthew/Maildir/cur # move potential messages out to the proper new/... directory # if mv complains about nonexistent .../*, all the better! mv 'cur:2,ST/'* 'new/'* 'tmp:2,ST/'* ../new/ # get rid of the bogus directories rmdir '???:2,ST/' new cd - and see if that fixes the problem. If rmdir fails because there are hidden files, see what they are and where to move them, if the {cur,tmp}:2,ST or new are empty, fine, someone accidentally ran maildirmake with bogus arguments.

[Dovecot] .files in dovecot-1.1.1
by John Baker 31 Jul '08

31 Jul '08

Hi there We had been using the stock Ubuntu Dapper Dovecot which is an early 1.0 beta but just upgraded to 1.1.1 to fix some read flag issues with Horde. Previously dovecot seemed to ignore files beginning with "." in the ~/mail (mbox format) directory but now shows them. There doesn't seem to be any switch in the dovcot.conf file to change this. Any such settings are about maildir. Is there anyway to make dovecot-1.1.1 ignore hidden files?

[Dovecot] login processes from attacks staying for hours
by Kai Schaetzl 31 Jul '08

31 Jul '08

I'm in the process of rolling out new setups with dovecot on CentOS 5.2 and I notice that dovecot doesn't handle the brute-force attacks too nice. I reduced the limit a bit to some reasonable looking value: login_max_processes_count = 32 to stop them earlier and the number of processes stops at that figure when an attack happens. However, it stays at this count for hours although the attack is already over since long. For instance, my monitoring alerts me at the moment when the process count for pop3-login goes over 20 processes. This happened on three machines at 2 am with a brute-force attack from the same source that didn't last longer than a minute or so. However, the process count dropped only at 7am under 20 on two machines and on the third machine it was still over 20 when I was in the office at 9 am and finally killed them. As these machines are all not in production yet, there weren't any other logins and the single brute-force ended within one minute according to the logs (obviously when pop3-logins hit the limit). Shouldn't these processes go down to login_processes_count (3) within a few minutes? An strace shows that they are mostly doing gettimeofday lookups (=sleeping). This is the default dovecot (1.07) coming with CentOS 5.2. I've been running only one other instance of dovecot in production (0.99.11) on CentOS 4.6 so far and I don't know which behavior that displayed in the past as I just recognize that I accidentally ommitted it from monitoring. :-( I had this mailing list searched for "brute-force" to see how others handle this and what dovecot provides to stop these attacks. I have found not many threads about this. There is one with a bit more information: "Delay on failed pw attempts" from January 1. Unfortunately, this functionality is only in a later version of dovecot and it's not clear if it was implemented or not or if it would be helpful. Was it implemented? This thread also mentions fail2ban which may be one way to go, although I don't like this log parsing approach too much. Does anyone use iptables for rate-limiting per IP on the pop/imap ports to prevent brute-force attacks?

[Dovecot] installing plugin (autocreate_plugin.c)

Hi I want to enable autocreate-plugin, I downloaded http://dovecot.org/patches/1.1/autocreate-plugin.c compiled as specified in comment and got autocreate_plugin.so but I'm not sure how do I install it. I have many plugins in /usr/local/lib/dovecot/ (it's FreeBSD) and subdirs, but they all have libXX_ prefixes (what do they mean?). I couldn't find any information about installing plugins on dovecot's wiki and I don't want to experiment as the server is live (not really important but still live). regards -- Marcin Gryszkalis, PGP 0x9F183FA3 jabber jid:mg@fork.pl, gg:2532994 http://the.fork.pl

[Dovecot] DoveCot IMAP and "inconsistent state" messages
by Chris Richards 30 Jul '08

30 Jul '08

I need some help troubleshooting this problem. It only shows up with IMAP connections. I initially thought it was related to SquirrelMail (because it gives me an 'EXPUNGE' error), but after attempting to send IMAP commands directly to the server as shown below, I'm thinking there is something else going on. The system configuration is PostFix as the MTA delivering to procmail in the mailbox (maildir format), with Dovecot handling POP3 and IMAP Postfix is version 2.3.3 Dovecot is version 1.0.rc15 procmail is version 3.22 2001/09/10 kernel is 2.6.18-53.1.14.el5, CentOS 5 There is additional info about the system configuration after the command sequence and log entries below. I've left my typos in, just in case they somehow bear on the problem. I omitted about 2050 messages from the mailbox FETCH listing, since they were all identical but for the message number, and I didn't figure you'd want to read all of that. :) Command sequence: [me@myserver~]$ telnet locahost 143 locahost/143: Name or service not known [me@myserver~]$ telnet localhost 143 Trying 127.0.0.1...

Is there a better/preferred way to have Postfix/procmail deliver mail to the maildir that will keep Dovecot IMAP happy? (There don't seem to be any issues with pure POP3 access). Thanks in advance for your help, and if there's anything else you need to know that I can provide, please ask. I've tried to provide as much information up front as I can. Later, Chris

[Dovecot] limiting the per-time connections from one single IP address
by suomi 28 Jul '08

28 Jul '08

Hi every we had a havy pop3 attach yesterday morning: about 400'000 connects in three hours from one single IP address within wandadoo.fr. the easiest way, to protect the dovecot server against such attacks would be to limit the number of connections anyone can open from one single IP address to the server in a certain time. this feature is available in newer versions of postfix, where i have limited the number of SMTP connections possible from one single IP address in one minute to three (3). i checked to see in the dovecot-wiki, but found only the #login_max_processes_count = 128 #login_max_connections = 256 which both do not contain neither a per-time constraint nor a per-IP-address constraint. is this already possible with current versions of deovecot? the dovecot -n: # 1.0.14: /etc/dovecot.conf ssl_cert_file: /etc/pki/ldap/mirador.cert.pem ssl_key_file: /etc/pki/ldap/mirador.key.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 51 mail_location: maildir:%h/%m mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: ldap args: /etc/openldap/dovecot.conf userdb: driver: ldap args: /etc/openldap/dovecot.conf thank you very much for any valid hint. suomi

[Dovecot] Strange checkpassword issue
by Andy Dills 28 Jul '08

28 Jul '08

I'm helping a friend setup a small mailserver using dovecot, and I'm finding a strange problem with checkpasswd that I haven't had on my servers. How is the following debug output even possible? Jul 25 12:12:20 company2 dovecot: auth(default): master out: USER 5 joe home=/var/mail/joe.com/joe/Maildir/ uid=1005 gid=1005 Jul 25 12:12:20 company2 dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 25 12:12:20 company2 dovecot: POP3(joe): open(/var/mail/joe) failed: Permission denied (euid=1005 egid=1005) I don't see how, when it's clearly getting the correct home directory from checkpassword, that it would then try the default mail directory. (mail_location is commented out, version 1.1.1) Here's the entire auth clause: auth default { mechanisms = plain login passdb checkpassword { args = /usr/local/sbin/checkpassword } userdb prefetch { } user = mailman # 1005,1005 socket listen { master { mode = 0666 } client { path = /var/run/dovecot/auth mode = 0660 user = postfix group = postfix } } } Any suggestions? I'm probably just missing something obvious, not having messed with setting this up for 6 months. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

Hello, I'm using dovecot 1.1.1 and dovecot-sieve-1.1.5 . I'm very interested in the notify plugin, I've tried many code which have generated some errors (coding errors that have been arrived in the .dovecot.sieve.err) but these errors are fixed. But Notify is still not working, I've the following in mail.log :deliver(webmaster@xxx.net): SIEVE ERROR: Unknown [unimplemented] notify method mailto:phxxx@xxp.comhere is my .dovecot.sieve :require ["fileinto", "notify"];# Move spam to spam folderif exists "X-Spam-Flag" { fileinto "spam"; # Stop here so that we do not reply on spams stop;}notify :method "mailto:phxxx@xxp.com":message "Vous avez recu un message sur votre adresse"; # Don't send any further notifications stop;What's wrong? I've tried example from http://www.ietf.org/internet-drafts/draft-ietf-sieve-notify-12.txt but they are not working.Thanks for helpPhilippe _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

[Dovecot] odd pam_authenticate() failed: authentication error followed by successful imap-login

I am seeing the following errors in my log: Jul 27 18:14:23 aegis dovecot: auth-worker(default_with_listener): pam(user(a)host.org,74.72.46.170): pam_authenticate() failed: authentication error Jul 27 18:14:23 aegis dovecot: imap-login: Login: user=<user(a)host.org>, method=PLAIN, rip=74.72.46.170, lip=206.251.255.39, TLS This happens *only* for virtual users; local UNIX users authenticate without that first error. However, all users are able to view mail, but that default_with_listener (which I setup just so Postfix could use dovecot to authenticate SASL senders) error only occurs for virtual users. Why is default_with_listener getting involved when users are trying to connect to dovecot directly without any involvement of Postfix?

[Dovecot] dovecot.sieve file location?
by kbajwa 28 Jul '08

28 Jul '08

CentOS 5.2 Postfix-2.3.3 Dovecot-1.1.1 Dovecot.Sieve-1.1.5 I have setup with: home_mailbox = Maildir/ (/etc/postfix/main.cf) & mail-location = maildir:~/Maildir (/etc/dovecot.conf) I have created a 'test' user to test Sieve 'Vacation' setup. My questions are: 1. Which folder '.dovecot.sieve' script is copied into? Is it 'home/test' -or- 'home/test/Maildir' or someplace else? 2. '.dovecot.sieve' script parameter ":days 1" means that the reply is sent once a day. Is it possible to send the reply 'immediately'? Kirti

[Dovecot] mail extra field to override default mail_location for only certain users
by Sahil Tandon 27 Jul '08

27 Jul '08

I am running version 1.1.1 with mail_location: maildir:~/Maildir. This is working great as all our users have UNIX accounts with nologin shells. New domains (and their users) are about to come online and we would like to migrate to a setup with virtual mailboxes/users. From the wiki and comments within dovecot.conf, I see it is possible to do this piecemeal so both local and virtual users can co-exist during the transition. My question is how to keep things working as they are for existing users/domains (which will be migrated later), and use the virtual mailboxes (and thus, a different mail_location) exclusively for the new users. I understand that multiple userdbs and passdbs can be specified, and this will take care of authentication. On http://wiki.dovecot.org/VirtualUsers#homedirs it is stated that "The userdb can return the mail extra field to override the default mail_location setting. Usually you shouldn't need this." Where is this mail extra field defined? In the userdb passwd-file or somewhere within dovecot.conf? If the former, would something like this suffice (mind the wrapping): user@domain.org::5000:5000::/home/vhosts/domain.org/:/usr/sbin/nologin::mail=m aildir:/home/vhosts/%d/%n Thanks, -- Sahil Tandon <sahil(a)tandon.net>

Re: [Dovecot] how to store flags \Seen into read-only mailbox?

I was looking for workaround, and tried to use one uid for all users, and ACL plugin to give permissions like: --- owner lrwstiekxa anyone rls --- rls should mean read, lookup and write-seen. Read and lookup works, and as soon as I remove these letters I can't read mail folder. But 's' is not working, I'm getting the same: --- 7 OK Store ignored with read-only mailbox. --- in rawlogs I can not find a way for users to keep their own track of what messages have been \Seen in read-only shared folder. -- Sergey Ivanov. ----- seriv(a)parkheights.dyndns.org wrote: > This problem is apparently about changeset > http://hg.dovecot.org/dovecot-1.1/rev/eec74a6ad62e. > This change makes dovecot behaviour different from what is described > in wiki, about sharing and making private /Seen flags, > see http://wiki.dovecot.org/SharedMailboxes?highlight=(flags are > shared or private) > When I've tried to revert it, first time with my client it worked > perfectly. > But then clients were not able to open any mail folders, and imap > processes were dying. > -- > Sergey Ivanov.

[Dovecot] Dovecot 1.1.2, SIGABRT on copy mail
by Andreas M. Kirchwitz 25 Jul '08

25 Jul '08

Hi folks, with the brandnew release Dovecot 1.1.2, the daemon killed itself with signal 6 (SIGABRT) when trying to save a mail from the INBOX to another folder. The mail client is PINE 4.64. After reconnecting to the IMAP server, the mail was actually copied to the destination folder, but the original mail was still in the INBOX and not flagged as "deleted". This is the panic: Jul 25 02:13:25 linux dovecot: Panic: IMAP(user2): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) Jul 25 02:13:25 linux dovecot: IMAP(user2): Raw backtrace: imap [0x80cf8e0] -> imap [0x80cf93a] -> imap [0x80cf26c] -> imap [0x809d11a] -> imap(index_mailbox_set_recent_seq+0x3e) [0x809d15e] -> imap(mbox_sync+0x105d) [0x80823fd] -> imap [0x807a454] -> imap(index_transaction_commit+0x4e) [0x809ddfe] -> imap(cmd_copy+0x35f) [0x805b26f] -> imap [0x805fd7c] -> imap [0x805fe25] -> imap [0x80605e5] -> imap(client_input+0x5e) [0x80607fe] -> imap(io_loop_handler_run+0x100) [0x80d7230] -> imap(io_loop_run+0x28) [0x80d63c8] -> imap(main+0x4a1) [0x8068321] -> /lib/libc.so.6(__libc_start_main+0xe0) [0x149390] -> imap [0x805a101] Jul 25 02:13:25 linux dovecot: child 7954 (imap) killed with signal 6 Thus, the daemon died somewhere between successfully saving a copy of the mail from INBOX to the destination folder and flagging it to be deleted in the INBOX. Just a couple of minutes later, Dovecot died again. Wanted to save a message from INBOX to another folder. But this time, the message wasn't written to the destination folder. As before, the original mail in the INBOX didn't change any flags.

[Dovecot] dovecot.conf permissions
by Dan Horák 24 Jul '08

24 Jul '08

Hi, I have a little problem with defining the right permissions for dovecot.conf. The main problem is that the password for SSL certificates is stored there and the conf file is world readable by default, which makes a security problem [1]. It is not a problem to restrict the permissions to 0600, dovecot will still work, but then deliver cannot work as it reads the conf too, but it runs under arbitrary user. So my last iteration is 0640 as permission and root:mail as ownership, but that expects that deliver is run with group = mail. For the long term solution I would prefer to move the password into a separate config file so the permissions can be properly restricted there. What are your opinions?

[Dovecot] Delivery notifications
by Brandon Keepers 24 Jul '08

24 Jul '08

I'm working on an application that is backed by Postfix 2.3.8 and Dovecot 1.0.13, configured with virtual domains, for handling messaging. I need to be able to send the notification (such as "You've received a new message on SomeAwesomeService. Click here to check it out", It's evil, I know) to a different email address, such as a mobile device. Eventually, we want to do other things like clear web page caches when a message is received, or sending IM notifications, but that's for another day. So basically, we want to notify our application whenever a new mail is received, and it can do all the magical things that it needs to do. I was hoping to get some feedback on the different approaches I'm looking at. From what I can tell, there's not a way to deliver to multiple virtual transports in postfix, so here's the options I see: * Content filter I could set up a "content filter" that just delivers the mail to the application, and then re-injects it back into postfix. This seems like more work than the other options just because I have to worry about re- injecting the message * Intercept delivery Replace the dovecot deliver command with a custom one that calls the dovecot deliver and then passes the message on to the application. I've written a little proof of concept for this and it seems to work, but just seem shady. * Sieve Dovecot supports Sieve, so I could just have a global sieve script that sends the notifications. This is definitely the solution I'm leaning towards. Are there any better options? Do you think this will have a significant impact on performance? Am I crazy? Thanks, Brandon

[Dovecot] making IMAP quicker on LAN
by Andrew Von Cid 24 Jul '08

24 Jul '08

Hi all, I keep on hitting this problem when migrating new clients from POP or local IMAP servers (hosted on their LAN's) to my Dovecot setup, which is hosted properly in a data center. People usually complain that it's slower and although they're getting a kick ass mail setup it doesn't look good from their point of view. I'm wondering if there is anything I could do to speed it up on their LAN's. What I mean is probably a caching IMAP proxy or some sort of replication to a local Dovecot server. Is this something Dovecot can do? I'd be really grateful for any opinions on how to tackle this problem. Many thanks, Andrew.

[Dovecot] how to store flags \Seen into read-only mailbox?
by seriv＠parkheights.dyndns.org 24 Jul '08

24 Jul '08

Hi, I'm trying to use dovecot for storing mailing lists and read-only access for users. The OS is Solaris, authentication for all readers of these lists are from Ldap through PAM, and one local user "listuser" will receive all mail and store them into it's folders (Maildirs). These maildirs are readable (read-only) for all others and they are shared by setting --- mail_location: maildir:/home/vmail/listuser/Maildir:CONTROL=/home/vmail/%u/Maildir/control:INDEX=/home/vmail/%u/Maildir/index --- Mail became readable because in each mail folder to be shared there is dovecot-shared with mode 064, and all users included into his group. But this is the problem: how to have flag \Seen stored in read-only mailbox? As recorded by rawlog, it is ignored now: --- bash-3.00# cat 20080724-103219-10616.in 3 namespace 4 lsub "" "*" 5 list "" "INBOX" 6 list "" "Trash" 7 create "Trash" 8 select "OmniTI.FreeLotto.Ops" 9 UID fetch 1:* (FLAGS) 10 uid store 1:3 +Flags (\Seen) 11 IDLE DONE 12 close 13 logout bash-3.00# cat 20080724-103219-10616.out * OK [RAWLOG TIMESTAMP] 2008-07-24 10:32:19 * NAMESPACE (("" "."))

Hmm. I don't necessarily see that as a desirable feature because in the case that something is actually wrong with the spam tagging you want to notice it isn't working right. If you really need that, just don't set an error when it happens and do nothing, allowing the move. johannes

There are a couple of tricky mbox issues left, but I'm not sure if I can do anything about them unless someone can show me how to reproduce the problems. There are quite a lot of new features in v1.1.2 actually. Most of them are in plugins so hopefully they shouldn't destabilize anything. Anyway I tought I'd just in case put out a quick release candidate so at least a few people could try it. I'll probably make the final v1.1.2 release in a day or two. So, please test: http://dovecot.org/tmp/dovecot-1.1.2-rc.tar.gz Largest changes since v1.1.1 are: + Added full text search indexing support for Apache Lucene Solr server: http://wiki.dovecot.org/Plugins/FTS/Solr + IMAP SORT: Added X-SCORE sort key for use with Solr searches. + zlib plugin supports now bzip2 also. + quota: All backends now take noenforcing parameter. + Maildir: Add ,S=<size> to maildir filename whenever quota plugin is loaded, even when not using Maildir++ quota. + deliver: Allow lda section to override plugin settings. + deliver: Giving a -m <namespace prefix> parameter now silently saves the mail to INBOX. This is useful for e.g. -m INBOX/${extension} + Added a new maildirlock utility for write-locking Dovecot Maildir. + dict-sql: Support non-MySQL databases by assuming they implement the "INSERT .. ON DUPLICATE KEY" using an INSERT trigger. - SORT: Fixed several crashes/errors with sort indexing. - IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions didn't include Content-Location support. - IMAP: Fixed bugs with listing INBOX. - Maildir: maildirfolder file wasn't created when dovecot-shared file existed on the root directory - deliver didn't expand %variables in namespace location settings. - zlib: Copying non-compressed messages resulted in empty mails (except when hardlink-copying between maildirs). - mbox-snarf plugin was somewhat broken - deliver + Maildir: If uidlist couldn't be locked while saving, we might have assert-crashed

[Dovecot] Problems with deliver and account resolving
by Andreas Podgurski 24 Jul '08

24 Jul '08

Hi! I'm currently setting up my first mailsystem based on dovecot. For a far way, working with dovecot was very convenient, but after I had to integrate deliver, it became massivly painful. My components are postfix as MTA, postgresql as user database and dovecot as IMAP server. When translating the mail adresse into the account name, something goes terribly wrong (Mail adresses modified to protect against spam, think about them in correct format): dovecot: Jul 22 01:48:13 Info: auth(default-listen): master in: USER 1 Andreas.Podgurski_at_MediaGUILD.de service=deliver dovecot: Jul 22 01:48:13 Info: auth(default-listen): prefetch(Andreas.Podgurski_at_MediaGUILD.de): passdb didn't return userdb entries, trying the next userdb dovecot: Jul 22 01:48:13 Info: auth(default-listen): sql(Andreas.Podgurski_at_MediaGUILD.de): SELECT 1011 AS uid,1011 AS gid,'/var/www/jade/mail/' || admin.username AS home,admin.username AS user FROM admin,email WHERE lower(email.local_address) = lower('Andreas.Podgurski') AND email.receiver = admin.id; dovecot: Jul 22 01:48:13 Info: auth(default-listen): auth(Andreas.Podgurski_at_MediaGUILD.de): username changed Andreas.Podgurski_at_MediaGUILD.de -> SunAdmin dovecot: Jul 22 01:48:13 Info: auth(default-listen): master out: USER 1 SunAdmin uid=1011 gid=1011 home=/var/www/jade/mail/SunAdmin deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Error: mkdir(/var/www/jade/mail/Andreas.Podgurski_at_MediaGUILD.de/cur) failed: Permission denied deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Info: msgid=<20080721234813.302260(a)gmx.net>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2008-07-22 01:48:13] As you can see, the account SunAdmin has an email adresse andreas.podgurski_at_mediaguild.de assigned. The database seems to reveil the username correctly, but after that, deliver continues to use the original mail adresse, not the account name returned by the auth master. Any idea, where my solution went the wrong way? The uid/gid belong to vmail:vmail, which is used for the auth-master, as well as for running deliver and to dispatch the postfix messages. Btw., I ask myself, how dovecot can assume to use prefetch in this case, as prefetch bases upon the password query, which has to fail in this case, as there is no password. Shouldn't it not even try to use the prefetch values there...? Thanks in advance, Andreas Podgurski -- Psssst! Schon vom neuen GMX MultiMessenger gehört?

[Dovecot] cosmetic: "userdb" checkpassword
by Heiko Schlichting 24 Jul '08

24 Jul '08

Hi, $ dovecot --build-options Build options: ioloop=epoll notify=inotify Mail storages: maildir SQL drivers: Passdb: checkpassword Userdb: checkpassword prefetch Isn't "checkpassword" misplaced in the userdb list? For me it seems that USERDB_CHECKPASSWORD is only used in configure and for printing the build-options. Additionally checkpassword protocol does not makes any sense for a userdb. It could be used only for passdb plus prefetching userdb. Therefore I suggest to remove USERDB_CHECKPASSWORD to make this more obvious althought this is only cosmetic.

[Dovecot] Problem authenticating iPod Touch
by Mark Leisher 24 Jul '08

24 Jul '08

Given the (slightly edited) config info below, iPod Touch users are unable to connect, leaving the following message in the log file: dovecot: Jul 23 10:00:40 Info: imap-login: Disconnected (auth failed, 0 attempts): rip=1.2.3.4, lip=5.6.7.8, TLS handshaking: Disconnected Even with maximum logging on, no other error messages seem related to this problem. Am I missing something simple I didn't catch in the list archives? Or is it more likely a problem on the iPod side? The iPods connect to our non-dovecot IMAP servers with no problem. # 1.1.1: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/imap-dovecot listen: *:143 ssl_listen *:943 ssl_cert_file: /etc/ssl/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: _dovecot login_greeting: IMAP ready. login_processes_count: 10 login_max_processes_count: 30 mail_location: maildir:~/Maildir mail_nfs_index: yes auth default: passdb: driver: passwd userdb: driver: passwd -- Mark Leisher

[Dovecot] \HasNoChildren versus \Noinferiors in ACL plugin and no CREATE permission
by Heiko Schlichting 23 Jul '08

23 Jul '08

Hi, using ACL plugin with dovecot 1.1.1 I expected that a Maildir was listed as * LIST (\NoInferiors) "/" "Foldername" if "create" (k) permission is not set in ACLs and there doesn't exists any subfolders. But to my surprise, dovecot gives the following output: * LIST (\HasNoChildren) "/" "Foldername" Therefore the client (here: SquirrelMail) does not know about the inability to create subfolders and offers "Foldername" in the selection for the parent folder. If there are exists already subfolders of "Foldername", dovecot has to use \HasChildren and not \NoInferiors. But in other cases \NoInferiors should be the correct answer and not \HasNoChildren. Or am I totally wrong?
