[Dovecot] Chown ChgrpNoPerm problem
by Robert JR 10 Sep '12

10 Sep '12

Hello, I just have a one simple question. my logs has the following entries Sep 9 02:48:10 dovecot: pop3(r): Error: fchown(/home/r/mail/.imap/INBOX/dovecot.index.log.newlock, -1, 12(mail)) failed: Operation not permitted (egid=501(r), group based on /var/mail/r) Sep 9 11:22:30 dovecot: pop3(r): Error: fchown(/home/r/.imap/INBOX/dovecot.index.log.newlock, -1, 12(mail)) failed: Operation not permitted (egid=501(r), group based on /var/mail/r) i know that chmod 0600 /var/mail , will solve the problem and i will no longer receive the above errors again But my question is that incase i did not set chmod /var/mail 0600, can i ignore such errors, is these errors harmful ? if this errors keep coming and i ignored them would this cause mbx corruption .. please advise My dovecot conf is disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mymail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Thanks.

[Dovecot] ChgrpNoPerm issue
by Robert JR 09 Sep '12

09 Sep '12

I have dovecot version 2.0.9 I am confused about this article http://wiki2.dovecot.org/Errors/ChgrpNoPerm my mail_location = mbox:~/mymail:INBOX=/var/mail/%u So my inbox is at var/mail/ and my imap folder is /home/user/mymail The problem is /var/mail (Owner is useraccount and the group us mail) , and here comes the problem Dovecot keeps trying to chown the imap folder inside the homedirectory with user:mail account and since And this is the reason of error that appears in my log file. The option mail_access_groups=mail solve the problem.. but I read it is not secure.. With my current configutation, users login with imap to read mail , can they use any the mail_access_groups=mail and read other poeple mail ? does my configutation is a shard mailbox and could be unsecure.. my main quesion , for my current configuration , can i use mail_access_groups=mail safely or can some user use this to read other people mail ? attached my configuration. why didnot have this issue with uw-imapd? and why dovecot try to chown the .imap folder with the mail group ? dovecot -n output is # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.2.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mymail:INBOX=/var/mail/%u mbox_write_locks = fcntl passdb { driver = pam } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } [ Robert

[Dovecot] Auth worker max line size
by Emmanuel Dreyfus 09 Sep '12

09 Sep '12

Hello I have been playing with some exotic authentication scheme with Dovecot and PAM. That involves sending really large base64 encoded data as the IMAP password, and I have hit a line limit in Dovecot, with AUTH_WORKER_MAX_LINE_LENGTH set to 1024. This limit is especially frustrating since other parts of the software use much larger limits: MAX_INBUF_SIZE 4096 MAX_IMAP_LINE 8192 AUTH_CLIENT_MAX_LINE_LENGTH 8192 I had to make the patch attached below to get my authentication working. I can live with this local patch, but given the much more liberal limits of MAX_INBUF_SIZE at 4096 makes we wonder if this 1024 limit on AUTH_WORKER_MAX_LINE_LENGTH could not be a bug. Or is there a security concern at using more than 1kB? Opinions?

[Dovecot] Vpopmail Dynamic Authentication Module
by Eric Sisolak 08 Sep '12

08 Sep '12

Hello, We currently use qmail with vpopmail for e-mail and are looking to switch from courier-imap to dovecot for IMAP on our RedHat EL 5 systems. Our goal is to use the dovecot RPM supplied by RH (v1.0.7) if at all possible. We can do this if we are able to dynamically load the vpopmail auth module. The wiki (http://wiki.dovecot.org/CompilingSource) notes that this should be possible: Dovecot can also dynamically load authentication modules from the $prefix/lib/dovecot/auth/ directory. Binary packages builders should use them for authentication modules which require external libraries (e. g. LDAP and vpopmail). There is no standard way to build them as modules currently, but something like this should work: gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_VPOPMAIL -DPASSDB_VPOPMAIL \-I../.. -I../lib userdb-vpopmail.c passdb-vpopmail.c -o vpopmail.so \-lvpopmail I had to modify the command to build the module, but was able to successfully build it: gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_VPOPMAIL -DPASSDB_VPOPMAIL -I../.. -I../lib -I/home/vpopmail/include -I/home/vpopmail/lib userdb-vpopmail.c passdb-vpopmail.c -o vpopmail.so -L/home/vpopmail/lib/libvpopmail.a I am unable to get the module to load properly. Dovecot built with --with-vpopmail works perfectly. When I start dovecot and it tries to load the module it reports: Aug 23 16:48:18 ctd-nix1 dovecot: Dovecot v1.0.7 starting up Aug 23 16:48:18 ctd-nix1 dovecot: auth(default): dlopen(/usr/lib64/dovecot/auth/vpopmail.so) failed: /usr/lib64/dovecot/auth/vpopmail.so: undefined symbol: vclose Aug 23 16:48:18 ctd-nix1 dovecot: auth(default): dlsym(passdb_vpopmail) failed: dovecot-auth: undefined symbol: passdb_vpopmail Aug 23 16:48:18 ctd-nix1 dovecot: auth(default): Unknown passdb driver 'vpopmail' (typo, or Dovecot was built without support for it?

I upgraded dovecot from 1.1 to 2.1.8 pop3/imap works but i have a problem. i use pop3 protocol on outlook 2010 for my account. and i set keep my mails on the server for 5 days or until i delete them.

[Dovecot] Disconnect users for a distinct period of time?
by Michael Grimm 07 Sep '12

07 Sep '12

Hi -- Today, I've learned who to disable incoming mail delivery to dovecot (accepted by postfix), temporarily. Now, I would like to know if there is a way to make a "doveadm kick -A" a permanent disconnect until one would allow reconnects, again? This should be done *without* shutting down dovecot or *extensive* re-configuration. A "doveadm block -u <joe> -m 'sorry: running maintenance, please, come back later'" alike tool/funtionality would be ideal. Background: I would like to avoid any modification of my user's maildirs by a running dovecot server while modifying maildir formats, mdbox_rotate_size setting, and alike, where I would need doveadm/dsnyc access to userdb. (I know there a ways to achieve this without downtimes, and I have already done so.) I just want to be sure that I haven't overseen such a tool/functionality in the documentation. Did I or didn't I? Thanks and regards, Michael

I'm not sure that the auth cache holds that information, but I think you can at least invalidate a particular auth cache entry by 1) Changing the user password (and save the previous hash) 2) Authenticate using the new credentials (and invalidate the auth cache entry). For example, you can just do a manual connection on your dovecot server x login someuser newpassword This will replace the cache entry with a new one. 3) When you are ready to put the account back online, change the password back to the original. A password mismatch forces a resync to your authentication system which will restore the auth cache. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] different userdb and/or passdb for lmtp and pop3/imap?
by Gábor Lénárt 06 Sep '12

06 Sep '12

Dear All, I have a bit complex question about ldap based user/passdb with some twists caused by the LDAP schema I have to use. It's complex for me at least, since it's my first time to try to setup any dovecot install which is more than a "trivial" thing eg for some unix system users. What I'd like to do: Users are stored in LDAP with the following schema: storageMailUid: contains user's uid in x@z format, and it CAN be different than mail address. This value is used to login (pop3/imap) and to get the maildir path (well, home) in the form of /mailstorage/z/x/ regardless of the value of the "mail" attribute. If @z part is missing (I mean the user supplied login, not the LDAP!), some default value (example.com) should be treated (I guess that's easy: auth_default_realm may be enough, isn't it). It is NOT possible to login via pop3/imap with mail, only with storageMailUid! This storageMailUid can specify a string which is not even an existing mail address, of course. mail: contains user's mail address, or even mail addresses (there can be more mail addresses - more mail ldap attributes - for a single ldap entry). This attribute cannot be used for pop3/imap login, neither it counts to resolve the maildir path, it only counts when a mail is received: the location of the user's maildir must be got from storageMailUid. storageMailQuota: it contains the quota value (in bytes) for the given user, which should be enforced on receiving mail, or by using IMAP (not counting the Trash folder which is a fixed size for all users and it must be handled outside of this). All user maildirs have the same fixed unix UID/GID, which is not stored in LDAP, but must be configured statically. "Home directory" of the user is also not stored in LDAP, it must be got from storageMailUid LDAP parameter. Mails are received via LMTP only. I'd like to use prefetchdb to minimalize the amount of LDAP lookups (however I can live without that). I am unsure if auth_bind is OK, or it should not be used, currently I'd like to play with auth_bind, since it worked before on other servers well. I'm totally lost with the user_attrs/pass_attrs to create this kind of configuration. In case of static userdb, it was easy to set up: passdb { args = /etc/dovecot/dovecot-ldap-passdb.conf driver = ldap } userdb { args = uid=vmail gid=vmail home=/mailstorage/%Ld/%Ln driver = static } With this, pop3/imap worked (quota was not of the scope yet, though), however lmtp is not ("passdb doesn't support lookups, can't verify user's existence" which is odd for me, as userdb does not support it in my opinion). Please, give some suggestion how to set up userdb and passdb to support this configuration which works with the described scenario. I should also set iterate_filter and iterate_attrs I guess, so some doveadm commands can work then (-A stuffs, I guess). I am also not sure if auth service should be used or not (I mean extra configuration related): since I want LMTP not LDA, I guessed I don't need it, but I am not sure. I am also confused, because on receiving a mail (via LMTP) different kind of LDAP lookup is needed: then mail must be searched, but it's storageMailUid based lookup in case of pop3 or imap login ... Is it possible to give different userdb/passdb for lmtp and pop3/imap? In theory it's even possible to have x(a)example.com as mail and y(a)example.com as storageMailUid for one user, and the opposite for the another, so lookups cannot be done together for mail and storageMailUid. The LDAP schema/rest of the system works this way, not an option to change. Any help is greatly welcomed. Thanks a lot in advance, Gábor

[Dovecot] managesieve problem
by Léon Keijser 06 Sep '12

06 Sep '12

Hi, I'm using roundcube in combination with postfix (2.6.6), dovecot (2.0.9) and pigeonhole (2.0.9). All works well except sieve. I've already posted on the roundcube forum (http://www.roundcubeforum.net/index.php/topic,9690.0.html ) but was told I should ask here since it's more likely a dovecot issue rather than roundcube. The problem is that if I want to manage sieve filters from roundcube, I get this error in maillog: Sep 5 12:55:39 emperor dovecot: managesieve-login: Login: user=<leon(a)EXAMPLE.COM>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=1575, secured Sep 5 12:55:39 emperor dovecot: managesieve(leon(a)EXAMPLE.COM): Error: sieve-storage: stat((null)) failed: Bad address Sep 5 12:55:39 emperor dovecot: managesieve(leon(a)EXAMPLE.COM): Error: sieve-storage: stat((null)) failed: Bad address Sep 5 12:55:39 emperor dovecot: managesieve(leon(a)EXAMPLE.COM): Fatal: Failed to open Sieve storage The managesieve daemon is listening though: emperor ~ # netstat -tlpne | grep dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 0 1275042 362/dovecot tcp 0 0 0.0.0.0:2000 0.0.0.0:* LISTEN 0 1275037 362/dovecot tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 0 1275035 362/dovecot tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 0 1275044 362/dovecot tcp 0 0 :::143 :::* LISTEN 0 1275043 362/dovecot tcp 0 0 :::2000 :::* LISTEN 0 1275038 362/dovecot tcp 0 0 :::4190 :::* LISTEN 0 1275036 362/dovecot tcp 0 0 :::993 :::* LISTEN 0 1275045 362/dovecot emperor ~ # telnet localhost 4190 Trying 127.0.0.1...

[Dovecot] Length of attachment filenames
by Fuhrmann, Hauke 06 Sep '12

06 Sep '12

Hi there, I have a beginners question to Dovecot: does it have a restriction on the supported length and character encodings of filenames of attachments? Can filenames be arbitrary large?

[Dovecot] dovecot stats: useful data to gather
by Patrick Ben Koetter 06 Sep '12

06 Sep '12

Timo, following our discussion on dovecot stats at the LinuxTag 2012 my team and I sat down and put together a list of stat items we think to be useful in daily dovecot usage. Besides pulling together all the data we also think it would be useful to have an SNMP interface to access the stats. Our offer to create and contribute a standalone web interface for dovecot stats stands. Here are the stats we believe to be useful: Login/Logout - total number login success/time - total number login failure/time - total number per authentication mechanism - total number plain sessions - total number STARTTLS sessions - total number of currently connected users (pop3/pop3s/imap/imaps/managesieve) - login names of connected users (not really stats, but great for actions regarding those uses e.g. force logout) - total number logout commands/time - total number BYE responses (autologout) Mailbox state - Inflow rate (number incoming messages/time) - Deleted rate (number \Deleted flagged messages/time) - Expunge rate (number Expunge operations/time) - total number current messages mailboxes normal storage - total number current messages mailboxes alt storage - total number read messages mailboxes normal storage - total number read messages mailboxes alt storage - per user number current messages mailboxes normal storage - per user number current messages mailboxes alt storage - per user number read messages mailboxes normal storage - per user number read messages mailboxes alt storage Mailbox Quota - total number persons under soft-quota per quota - total number persons above or equal soft-quota per quota - total number persons above or equal hard-quota per quota Performance - minimum time to write a message - maximum time to write a message - average time to write a message - minimum time to modify a message - maximum time to modify a message - average time to modify a message - minimum time to delete a message - maximum time to delete a message - average time to delete a message - minimum time search operations - maximum time search operations - average time search operations Regards, p@rick -- state of mind () http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

I frequently see the above log messages when the client and the server get their security protocol (SSL/TLS) and ports crossed up (i.e. trying IMAP/SSL on port 143 or trying IMAP/TLS on port 993). Try fiddling with TB's setting here and see if anything shakes loose. You can also use openssl and simulate the server end and maybe that will shed light on the situation: (You'll have to read the man page yourself to find all the options) openssl s_server -accept 993 ...

[Dovecot] mail_location / mail_home
by Denny Schierz 06 Sep '12

06 Sep '12

hi, I had a long (upgraded today from 2.0.17 to 2.1.9) time mail_location and mail_home at the same path, which I recognize know, that it wasn't a good idea, idea. On my testsystem I've set: mail_home = /imap/spool/%d/%1u/%u mail_location = maildir:~/:INDEX=~/ otherwise I don't have access to the mails anymore. Is that ok? cu denny

You could work out a cron job that does a "doveadm search ...", then diff it with one generated 24 hours ago, extract the common GID/UUIDs, then do a second pass to delete them. Not elegant, but it would probably work. (I just read the man page, and there doesn't seem to be an option to pipe the search like "doveadm search ... | doveadm expunge ...". You'll have to expunge one message at a time. Ugh.) Or maybe the advice "don't worry, be happy" applies here. I find that too many "mistake mitigation" features is counterproductive as users habitually relying on them, rather than being careful. Extending your grace period to a week will lessen the probability of this race condition. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Custom auth process in dovecot 2
by Richard Platel 04 Sep '12

04 Sep '12

Hi, I'm trying to upgrade from dovecot-1.1.x to 2.1.7. We have our own custom auth server process (because we want to do our own password validation and for other reasons) that listens on a UNIX domain socket and speaks the dovecot auth protocol. In dovecot 1.1 we could configure this with auth external { socket connect { master { path = /var/run/dovecot/auth.sock } } } as per http://wiki.dovecot.org/MainConfig I haven't been able to figure out how to do this in 2.1.7, is it possible?
