[Dovecot] Brute Force Blocking?
by Ben Cadieux 24 Dec '07

24 Dec '07

Hi Everyone, Before I begin, I'd just like to mention: I love dovecot. Thank you :) Anyway, today I had 8000 login attempts to my dovecot server in an hour before blocking the IP with my firewall. After googling, I didn't see very much discussion on the topic. There was some mention of blocksshd which was supposed to support dovecot in the next release (but doesn't appear to) and also fail2ban. While a script that parses logfiles will work, I'm not sure that this is the best way to go about handling repeated authentication failure. Would it not be best built into dovecot? Are there any plans for this? Best Regards, Ben Cadieux

[Dovecot] Compact all maildirs with dovecot-1.0.9?
by Jeff Kowalczyk 23 Dec '07

23 Dec '07

I'm running dovecot-1.0.9 on Gentoo Linux. I recently observed a large increase in disk usage on this dedicated mailserver. I attribute it to high spam traffic and/or large attachments for legit email retained on the server. How can I run a command equivalent to an IMAP client's 'Compact Folder' on the entire tree of maildirs under each /home/(user)? Thanks.

yep, originally I want Dovecot to behave exactly the same like our Cyrus environment regarding namespaces, in preparation of a migration :) The first login shows Dovecot output, second show Cyrus, for comparison...

[Dovecot] Squirrelmail + Dovecot + Maildir
by Vicki Stanfield 21 Dec '07

21 Dec '07

I have been struggling with getting my Fedora 7 box set up to use dovecot with Squirrelmail and Maildir. It works correctly with the exception of writing outgoing mail to the right folder (.Sent) or drafts (.Drafts). If I send a mail with Mutt, it writes the mail to the right place, so it has to be squirrelmail config or dovecot config. I want to use .Sent for sent-mail (~user/Maildir/.Sent) and .Drafts for drafts (~user/Maildir/.Drafts). Here is what I see in /etc/squirrelmail/config.php $optional_delimiter = '.'; [snip] $default_folder_prefix = ''; $trash_folder = 'Trash'; $sent_folder = 'Sent'; $draft_folder = 'Drafts'; $default_move_to_trash = true; $default_move_to_sent = true; $default_save_as_draft = true; The error in the browser is: * ERROR : Bad or malformed request.* Server responded: {830} BAD Error in IMAP command : Unknown command. and in the logs I see this: Dec 18 09:41:56 opus postfix/smtpd[12747]: connect from localhost[127.0.0.1] Dec 18 09:41:56 opus postfix/smtpd[12747]: 4CB7329B00B2: client=localhost[127.0.0.1] Dec 18 09:41:56 opus postfix/cleanup[12750]: 4CB7329B00B2: message-id=<51150.127.0.1.1.1197988916.squirrel(a)127.0.1.1> Dec 18 09:41:56 opus postfix/qmgr[2650]: 4CB7329B00B2: from=<vic(a)thepenguin.net>, size=1015, nrcpt=1 (queue active) Dec 18 09:41:56 opus postfix/smtpd[12747]: disconnect from localhost[127.0.0.1] Dec 18 09:41:56 opus dovecot: imap-login: Login: user=<vic>, method=PLAIN, rip=::ffff:127.0.1.1, lip=::ffff:127.0.1.1, secured Dec 18 09:41:56 opus dovecot: IMAP(vic): Disconnected: Too many invalid IMAP commands.

[Dovecot] namespace problem / 1.1beta11
by ja nein 21 Dec '07

21 Dec '07

Hi all, actually I got a problem with the namespaces in dovecot 1.1 beta11. It occured after purging index files and resynch via imapsync. Dovecot complains about "Unknown namespace", though it worked with versions before. I cannot comfirm for 1.1beta10, but I surely know 1.1beta9 worked with these settings. Example: From Folder [INBOX/Trash] To Folder [___________] To Folder ___________ does not exist Creating folder [___________] Couldn't create [___________]266 NO Unknown namespace. Used imapsync command: /home/imapsync/imapsync --host1 ip.of.host.1 --user1 user1 --password1 password --host2 127.0.0.1 --user2 user2 --password2 password --authmech2 LOGIN --regextrans2 s/\./_/g --delete2 --sep1 . --sep2 . --justfolders Another run with different namespace settings shows up the folders in Thunderbird as INBOX^2002, INBOX^Trash ans so on... My goal is to keep all client settings when migrating a bigger installation of cyrus to dovecot. For know all folders in Cyrus appear as subfolders of INBOX, which I had achieved with dovecot < 1.1beta11. Any ideas? Btw., as we work in a load balanced environment, LMTP delivery would be a great feature for upcoming releases, as it would enable people to use multiple frontends of SMTP servers without the need of connecting them to a somewhat shared file system. Forwarding all mail to a SMTP server on the machine running dovecot and doing delivery there isn't the favoured option (at least for us). And a huge thx to Timo on working that hard on such a great working product!

[Dovecot] Dovecot truncating messages and/or attachments
by fp＠kraptastic.com 21 Dec '07

21 Dec '07

Hello, I am having problems with Dovecot not sending clients emails bigger then 8-12k (it varies) or attachments bigger then 8-12k. I am also getting 'Corrupted transaction log file' errors ' unexpected end of file while reading header' I have deleted the dovecot.index.log, dovecot.index.cache, and dovecot.index several dozen times. I started off using Centos 5, with their package of dovecot 1.05, after seeing that there were problems in the package in the http://wiki.dovecot.org/WhyDoesItNotWork, I went with a source install of dovecot 1.09.

[Dovecot] about quota_warning behavior
by naoki 21 Dec '07

21 Dec '07

Hi, We've been using v1.0.5 +quota_warning patch, however quota_warning does't seem to be working properly. For example, in order to enable 80% over for quota warning, and we configured like following: ----------------------------------------------------------------------- plugin { quota_warning = storage=80%% /usr/local/path/to/plugin } ----------------------------------------------------------------------- But it does not work. However we set quota_warning value to 20%, it seems to be working. ----------------------------------------------------------------------- plugin { quota_warning =storage=20%% /usr/local/path/to/plugin } ----------------------------------------------------------------------- If this is the case, do we always have to set quota value to what we have after subtracting the required quota warning value from 100. for example, if we want quota warning value to be 70%, we actually have to write 30% in configuration?? Will there be another patch to fix this? Thanks -- Naoki Takazawa Marino Ltd., Yokohama, JAPAN

Re: [Dovecot] 1.1.Beta9 deliver problem: Unknown mail storage driver raw

Hi Velko, I recently hit the same problem. You have to add raw storage driver to your compile options, meaning "--with-storages=maildir,mbox,dbox,raw,cydir", that will do the trick. Maybe it would be good to update the description of available storage drivers in configure script.

[Dovecot] 1.1 beta 11 - no quota warnings
by adam_jh＠hotmail.com 21 Dec '07

21 Dec '07

Having tried and failed to get 1.0.8 with quota-rewrite to send warnings, I removed the 1.0.8 and installed the latest 1.1 - however I still can't get the warnings! Can someone advise what might be wrong - it must be my configuration?? To compile 1.1 I used ./configure --with-deliver --with-mysql. I've chopped and changed my conf till I'm blue in the face. My dovecot-mysql.conf file does not override the quota, I've enabled the debug and verbose = yes - but they don't mention any quota warnings, just normal delivered logs. What else can I do? The process I use is to add up the maildirsize totals, set a storage figure in the conf which makes the maildirsize just less than 95%, then restart dovecot, send an email - and nothing - no warning is triggered! Any help appreciated - I've spent so long on this now. adam # 1.1.beta11: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 pop3s ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot-login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:/var/vmail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: user: nobody verbose: yes debug: yes passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth user: postfix group: mail master: path: /var/run/dovecot/auth-master user: vmail group: mail plugin: quota: maildir quota_rule: *:storage=220000b quota_warning: storage=95%% /usr/local/bin/quota-warning 90

[Dovecot] imap+unix users and pop3+virtual users
by Wendell Turner 21 Dec '07

21 Dec '07

This should be simple, but I'm missing something. My virtual users cannot access their mail. I would like Unix users to get their mail via imap which is deposited in /var/spool/mail/username. (This works.) I would like virtual users to get their mail via pop3 which is deposited in /var/spool/mail/vhosts/example.com/auser/mail/inbox (postfix does in fact put the mail there). Those users can get authenticated via file /var/dovecot/passwd, but cannot retrieve their mail. The log message is shown below. The file/directory is there, but doesn't dovecot see it?

[Dovecot] upgrade to 1.1 and mail location
by lenny＠edpausa.com 21 Dec '07

21 Dec '07

I recently upgraded from 1.0.8 to 1.1-11 the only thing that was changed in the config file was the new syntax for mail location. default_mail_env = mbox:~/:INBOX=~/mbox to mail_location = mbox:~/:INBOX=~/mbox now some imap clients, like squirrellmail and pine have difficulties writting to Sent, Draft and sent-mail folders. In all cases the folders are visible and are present in .subsriptions file( although not seen as subscribed in squirrelmail), but the clients complain that folders already exist when trying to write to them after sending. has anyone run into this ? any suggestions ? thanks a lot.

[Dovecot] Dirsize quotas with 1.1beta9

Hi, Anyone able to get 'dirsize' quotas to work properly under 1.1beta9? I can get them to reflect the size of the INBOX properly, but it never seems to be adding up the size of the files in the folder directory itself. I'll keep hammering away at it if others are able to use dirsize with no problems, but wanted to check first. -- Dean Brooks dean(a)iglou.com

[Dovecot] Security hole #4: Specific LDAP + auth cache configuration may mix up user logins
by Timo Sirainen 21 Dec '07

21 Dec '07

Somehow I doubt there are any Dovecot setups left that unknowingly have this problem, but it still counts as a security hole. The possibility to cause this problem exists in Dovecot v1.0.rc11 and later. If you use: 1. passdb ldap with settings: - auth_bind = yes - auth_bind_userdn = no - base containing %variables required for unique user identification, e.g. base = dc=%d,dc=org - pass_filter not containing all %variables required for unique user identification - pass_attrs returning user-specific settings, such as user's home directory 2. userdb prefetch 3. auth_cache_size non-zero (0 is default) If two users with the same password and same pass_filter variables log in within auth_cache_ttl seconds (1h by default), the second user may get logged in with the first user's cached pass_attrs. For example if pass_attrs contained the user's home/mail directory, this would mean that the second user will be accessing the first user's mails. You most likely would have noticed this already by wondering why logins keep failing, unless pass_filter used also some %variables that most of the time uniquely identifies the user. For example %r (remote IP address) or %n (username without domain). You can fix this by upgrading to v1.0.10 (to be released soon), or using this patch: http://hg.dovecot.org/dovecot-1.0/raw-rev/2cedab21cd6d

[Dovecot] dovecot-auth: returning incorrect maildir for user (user seeing another user's mail)
by Brendan 20 Dec '07

20 Dec '07

timo, here is an bizarre bug for you: i had (foolishly, it turns out) configured dovecot-auth to do ldap authentication binding with a prefect userdb (configs at end of message). everything worked fine, although with huge numbers of pop logins per second we started to see some pileup in the pop3-login processes as they were all waiting for ldap responses on the single ldap connection. the auth caching was never getting hit (some interaction with the prefetch, i assume), but everything worked fine. or so i thought. we had complaints from a user saying they would occasionally pop another user's mail. after much digging, it turned out that if two or more users: - were logged/logging in at the same time - had the same password - got "lucky" then one of the users would occasionally end up with the other users' homedir/maildir. it didn't happen often (maybe once every 500-1000 login attempts), but it did happen. (i ended up writing a script that would pound the pop3 server with logins and look for the wrong number of messages in the inbox. it was not easy to trigger). i'd already realized that having the auth bind do a search and return that to prefetch was a bad idea (since it used a single ldap connection) and had already built a new config that used auth binding and userdb ldap - when we switched over to that config we were unable to replicate the problem again. so, it's not an issue for us right now. i've confirmed that the ldap server never returns the wrong homedir, so it must have been getting mixed up somehow in dovecot-auth. but it did seem like something you might want to dig into a bit, as it might indicate that something could be amiss somewhere in the auth code. that the problem only occured when the users had the same password seemed truly bizarre.. sorry i can't provide more details, it was very difficult to reproduce (and i was reproducing in a production environment and couldn't turn debug up). the auth section from the poorly behaving dovecot.conf: auth default { mechanisms = plain login passdb ldap { args = /opt/dovecot-1.0.3/etc/dovecot-ldap.conf } userdb prefetch { } user = mail } the poorly behaving dovecot-ldap.conf: hosts = ldap ldap_version = 3 auth_bind = yes base = uid=%u,o=imap user_global_uid = 8 user_global_gid = 8 dn = uid=imap@dovecot,o=imap dnpass = ****** pass_filter = (&(proto=%s)(remoteip=%r)(localip=%l)(mech=%m)(pid=%p)) pass_attrs = home=userdb_home,quota=userdb_quota,nologin=nologin,reason=reason,user=user note: the ldap server does some custom processing based on the filter - the filter was the easiest way to get them passed to it. (in case that looks a little wierd :)

[Dovecot] How to change dovecot's bounce message

20 Dec '07

Hi, I am using the quota plugin of dovecot. Dovecot is running as LDA for postfix. When the system is running into the quota limit, the bounce message reads as follows: > Your message was automatically rejected by Dovecot Mail Delivery Agent. > The following reason was given: > Quota exceeded Can I somehow change this message, to make it more userfriendly?

[Dovecot] Massive Dovecot auth errors too strange for me
by Rudi K. 20 Dec '07

20 Dec '07

Hello out there, im running Dovecot on "ubuntu Dapper" serving pop3 only in maildir-style, but the dove-auth-process refuses "answers" to the deliver or login-process from time to time, (several times a day), and I have no glue whats going on and why ... Debbugging password-Auth surprised me, as the transmitted password IS correct and allows an successfull authenification lots of hundreds times a day.... but suddenly runs into trouble .. here the logs ... (please take care..., I´m a newbie ;-) Dec 18 10:25:05 server dovecot: pop3-login: Disconnected: Inactivity: method=PLAIN, rip=91.9.201.219, lip=83.154.61.77 Dec 18 10:25:07 server deliver(user.yxz(a)somedom.de): User request from dovecot-auth timed out Dec 18 10:25:07 server postfix/pipe[22156]: 63861180062A7: to=<user.yxz(a)somedom.de>, relay=dovecot, delay=60, status=deferred (temporary failure) Dec 18 10:33:09 server dovecot: auth(default): ssha_verify(info(a)mydom.de): invalid SSHA base64 decode Dec 18 10:33:09 server dovecot: auth(default): cache(info(a)mydom.de,84.166.106.150): Password mismatch Dec 18 10:33:09 server dovecot: auth(default): cache(info(a)mydom.de,84.166.106.150): SSHA(1234) != '1234' Dec 18 10:33:11 server dovecot: auth(default): client out: FAIL^I56^Iuser=info(a)mydom.de Dec 18 10:33:11 server dovecot: auth(default): client out: FAIL^I57^Iuser=info(a)mydom.de root@server:~# dovecot --version 1.0.rc17 root@server:~# dovecot --build-options Build options: ioloop=poll notify=dnotify ipv6 openssl SQL drivers: mysql postgresql sqlite Passdb: checkpassword ldap pam passwd passwd-file shadow sql Userdb: checkpassword ldap passwd prefetch passwd-file sql static root@server:/etc/dovecot# grep -v '^ *$#.*$\?$' dovecot-ldap.conf hosts = localhost dn = cn=admin,dc=jdbit,dc=de dnpass = auth_bind = yes ldap_version = 3 base = ou=mailsystem,dc=jdbit,dc=de scope = subtree user_attrs = uid=user,userPassword=password user_filter = (&(objectClass=ekitsMailAccount)(|(uid=%u)(userAlias=%u))) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=ekitsMailAccount)(|(uid=%u)(userAlias=%u))) default_pass_scheme = SSHA user_global_uid = vmail user_global_gid = vmail root@server:~# dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 listen: mail.mydom.de disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_greeting: mail.mydom.de POP3-Server ready login_process_size: 64 login_processes_count: 64 first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_extra_groups: mail mail_location: maildir:/var/spool/dovecot/mail/%Ld/%Ln mail_executable: /usr/lib/dovecot/pop3 mail_process_size: 384 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: cache_ttl: 0 user: nobody worker_max_count: 60 passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: master: path: /var/run/dovecot/dovecot-auth-master mode: 384 user: vmail

[Dovecot] Question with versions and problem with IMAP
by Drew Weaver 20 Dec '07

20 Dec '07

General question I have is this. Recently my personal server which I receive e-mail for a domain which is just for playing with rebooted on its own and I had both an RPM version and a source version of dovecot installed on the same machine. The RPM version started first even though I had been running under the source built version up until this point (I originally found that for some reason the version centos built was missing something, maybe plugins, I don't remember now) Anyhow, the question I have is why did it insist that all of my mail was new mail? I quickly realized what the problem is, and I noticed that once I switched it back and forth between the old and new versions it properly updated the 'read vs unread' mail in IMAP, and even though dovecot was using the same configuration file with both binaries (/etc/dovecot.conf) it made such a huge difference. The reason I am asking is because I want to update my source version from 1.0.rc2 to 1.0.9 but I would really like to retain my read vs. unread mail. The RPM version in question is: 0.99.11 The problem I am facing is, today a large mailbox approx. 570M suddenly stopped working via IMAP in outlook express. (again on version 1.0.rc2) no changes have been made to the configuration for over a year. There are no errors in maillog here is the output however: Dec 18 09:49:53 mail dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=client, lip=server Dec 18 09:49:53 mail dovecot: IMAP(user): Effective uid=552, gid=100 Dec 18 09:49:53 mail dovecot: IMAP(user): Loading modules from directory: /usr/local/lib/dovecot/imap Dec 18 09:49:53 mail dovecot: IMAP(user): Module loaded: /usr/local/lib/dovecot/imap/lib01_quota_plugin.so Dec 18 09:49:53 mail dovecot: IMAP(user): Module loaded: /usr/local/lib/dovecot/imap/lib02_imap_quota_plugin.so Dec 18 09:49:53 mail dovecot: IMAP(user): maildir: data=/home/user/Maildir:INDEX=/mailaux/user:CONTROL=/mailaux/user Dec 18 09:49:53 mail dovecot: IMAP(user): maildir: root=/home/user/Maildir, index=/mailaux/user, control=/mailaux/user, inbox= Dec 18 09:49:53 mail dovecot: IMAP(user): fs quota add storage dir = /home/user/Maildir Dec 18 09:49:53 mail dovecot: IMAP(user): fs quota block device = /dev/sda1 Dec 18 09:49:53 mail dovecot: IMAP(user): fs quota mount point = /home Dec 18 09:49:55 mail dovecot: IMAP(user): Disconnected: Logged out Outlook express gives its usually helpful error message: Header download for the 'Inbox' folder did not complete.

[Dovecot] Upgrading from 1.0.rc2-1ubuntu2.2 on edgy

Hi Guys, Can anyone shed some light as to how I upgrade away from 1.0.rc2-1ubuntu2.2 on edgy? The usual aptitude upgrades aren't doing anything for me, and, downloading the package from another Ubuntu release, and trying a dpkg -i is causing lots of dependency errors. Daragh

It passes both endpoints (remote & local) through to dovecot . This lets you restrict smtp-auth just like pop3 or imap using the remote IP. In my case, I had played around with a quick hack for doing per-ip realming (using the local IP) w/ dovecot-sql.

[Dovecot] child (login) killed with signal 9
by Matt LaPlante 19 Dec '07

19 Dec '07

Hi, I'm running dovecot on an Ubuntu server (1:1.0.5-1ubuntu2). Dovecot provides pop3, imap, and sasl to postfix. The setup works quite nicely, however I do have one error that shows up repeatedly in my dovecot.log. <snip> dovecot: 2007-12-12 09:29:06 Error: child 32765 (login) killed with signal 9 dovecot: 2007-12-12 09:29:06 Error: child 18039 (login) killed with signal 9 dovecot: 2007-12-12 10:05:07 Error: child 26088 (login) killed with signal 9 dovecot: 2007-12-12 10:05:07 Error: child 5271 (login) killed with signal 9 dovecot: 2007-12-12 10:05:07 Error: child 5273 (login) killed with signal 9 <snip> I'm not aware that this is actually causing problems, but since it shows up several hundred times a day on a couple-user setup, I'm rather curious about what's causing it. Thanks, Matt

Clicking on an email would just sit there as if it is loading but nothing would happen - the read pane just remains blank. Is Dovecot going through every email (of many 10,000's) and counting up the sizes? Could this be made more efficient so it doesn't lock the account? This could I guess be a Thunderbird issue - it is a disappointingly imperfect client. Dan

[Dovecot] sieve & vacation question
by Ralf Hildebrandt 19 Dec '07

19 Dec '07

We have a setup where a Postfix gateway does virtual_alias rewriting of the envelope sender: ralf.hildebrandt(a)charite.de get rewritten to hildeb(a)postamt.charite.de The mail is then sent on to postamt.charite.de, the Mailbox server. There we use deliver & doecot. The sieve vacation recipient says it won't answer if: "The envelope recipient is not found in the message To:, Cc: or Bcc: fields." But this is never the case, since the envelope is being rewritten. How can I solve this conundrum? -- Ralf Hildebrandt (Ralf.Hildebrandt(a)charite.de) plonk(a)charite.de Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de The ashtray in my office proudly displays "Designed for Windows98/NT"

[Dovecot] Help please: Migrating Courier imap - Dovecot (Postfix virtual mailbox domains)
by Mark Piekos 17 Dec '07

17 Dec '07

I'm trying to migrate from qmail to postfix. The original server is combo of qmail and Courier imap (no pop mailboxes) I have a working Postfix config and had imap working with Courier imap on the new server. I thought I would experiment with Dovecot as it has some good press. I have moved the contents of my original maildir's to the new server and ste permissions and group membership appropriatley. I can read the 'Inbox' via Dovecot but non of the subfolders that I had configured. I have tried the 'manual' migration method as described in the faq without success (I can see the subfolders but no contents)and have tried running courier-dovecot-migrate.pl witt he same result. I'd be grateful for any advice. Kind regards, Mark.

Hello, v1.1.beta11 deliver crashes when quota exceeded. This also reveals another problem in v1.1.beta11 - imap process does not follow quota settings - this user copied(with imap client) to his imap folder large volume of emails and these emails significantly exceeded quota settings for this user, but imap process did not complain about it.

[Dovecot] Xen + NFS
by Eric 14 Dec '07

14 Dec '07

Thanks for Dovecot! I am currently testing several scenarios to help determine how to best implement dovecot for our environment. One scenario of particular interest is Maildir + NFS, load balanced between several servers running dovecot. I am not sure anyone would ever want to implement what I am about to describe here, but none-the-less, I thought I would mention it to the list to see if anyone has had the same experience, or could possibly help. What I am using to _test_ is a single server running RedHat Server 5 + Xen. Dom0 is acting as my NFS server, and a RedHat Server 5 guest running on the same machine is acting as my NFS client and dovecot server. I have a single directory exported from the NFS server which contains several home folders with inboxes stored in Maildir format. The problem I am having is when I open a POP3 connection from a separate machine, I see the following messages on the virtual server in /var/log/maillog and I am unable to retrieve mail: file maildir-uidlist.c: line 139 (maildir_uidlist_unlock): assertion failed: (uidlist->lock_count > 0) and more often: Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 It appears to be an issue with the login not having the proper permissions to create the dovecot.uidlist file, however, when I log in locally to the dovecot server with the POP3 account, I can read+write in the directory without problems. I suspect that I am missing something simple, but cannot seem to figure it out. dovecot-1.0-1.2.rc15.el5 RedHat Server 5 kernel: 2.6.18-8.1.14.el5xen dovecot -n: shutdown_clients: no 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 login_greeting: Server ready. mail_location: maildir:~/.maildir:INDEX=/var/spool/dovecot/%u maildir_copy_with_hardlinks: yes mbox_write_locks: dotlock fcntl 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 pop3_reuse_xuidl(default): no pop3_reuse_xuidl(imap): no pop3_reuse_xuidl(pop3): yes pop3_lock_session(default): no pop3_lock_session(imap): no pop3_lock_session(pop3): yes auth default: passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf nfs mount options: rw,rsize=32768,wsize=32768,hard,fg,lock,nfsvers=3,tcp,retrans=0,noac --------------------------------- Looking for last minute shopping deals?

I think I'm just going to move to 1.1 - however, I'm not keen on installing all the dev tools necessary on a production box. Does anyone have any pointers to web pages or keywords I can check to see what kind of safeguards are needed. The problem I have is building the the srpm to include the quota-rewrite with the trash plugin. I think it has been removed and I wanted to check if anyone knows any good reason not just simply re-enable it (though without the skills I'm not sure I'd do it). -SUBDIRS = acl convert quota imap-quota lazy-expunge mail-log trash $(ZLIB) +SUBDIRS = acl convert quota imap-quota lazy-expunge mail-log $(ZLIB) [root@test ~]# /etc/rc.d/init.d/dovecot start Starting Dovecot Imap: Warning: Corrected permissions for login directory /var/run/dovecot-login FPlugin trash not found from directory /usr/lib/dovecot/imap Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot.conf [FAILED] A year ago the same question was asked, but I'm not sure of any changes since then. >>> >From tss at iki.fi Sun Oct 15 22:44:38 2006 From: tss at iki.fi (Timo Sirainen) Date: Mon, 16 Oct 2006 00:44:38 +0300 Subject: [Dovecot] Apple Mail quota display In-Reply-To: <C49A984C-F2BF-4A40-84A4-7ED1F7264866(a)mac.com> References: <E94C8EAF-E17E-4E68-B43F-E990A632C4F9(a)mac.com> <1160339709.5137.125.camel@hurina> <C49A984C-F2BF-4A40-84A4-7ED1F7264866(a)mac.com> Message-ID: <1160948678.5448.85.camel@hurina> On Sat, 2006-10-14 at 01:13 -0700, Timothy Martin wrote: > I'm no wiz at applying diffs and compiling my own (i'm a BSD ports > kinda guy) but when i tried that diff i couldn't compile because > there looked to be a couple of lines that should have been removed > and the Trash plugin doesn't appear to be updated to work with the > quota rewrite.

No idea. Passing --user is easy, there's an example in the readme file for the antispam plugin.

[Dovecot] How to copy Spammail for learning out of Postfix and Dovecot (vmail)
by Sven Schmidt 13 Dec '07

13 Dec '07

Hi! I am using Postfix 2.3.8 and Dovecot 1.0.rc15. Virtual Domains and Mailboxes are configured. I tried to copy spammy Mail with Procmail, but Procmail only sees local mails. How to configure it to get a copy of spammy mails in a mbox or mail-dir?

[Dovecot] Dovecot Antispam Problem (Using mail sending backend)
by Justin Refice 13 Dec '07

13 Dec '07

I'm trying to setup DSPAM training using the mail-sending backend of the Antispam filter, unfortunately, things don't appear to be working. I've compiled it against the debian etch dovecot libraries, and the plugin itself builds, and doesn't report any errors when running. As a matter of fact, it doesn't report ANYTHING when running, except for the initialization code (DEBUG=syslog): imap: antispam: plugin initialising imap: antispam: "trash" is trash folder imap: antispam: "Trash" is trash folder imap: antispam: "Deleted Items" is trash folder imap: antispam: "spam" is spam folder imap: antispam: "Spam" is spam folder imap: antispam: "SPAM" is spam folder imap: antispam: "junk" is spam folder imap: antispam: "Junk" is spam folder imap: antispam: "Junk Mail" is spam folder imap: antispam: no unsure folders imap: antispam: mail backend spam address dspam-add(a)xxx.yyy imap: antispam: mail backend not-spam address dspam-fp(a)xxx.yyy imap: antispam: mail backend sendmail /usr/sbin/sendmail imap: antispam: mail backend tmpdir /tmp .... And that's it. I never hear from the plugin again, regardless of how many times I create/delete the SPAM folder, or how many times I move/copy into/out of the folder. The plugin is basically silent. I don't see the mails being sent/recieved, so I'm assuming that's it isn't doing anything at all. I can manually use the training addresses, so I know they're working. Any help would be appreciated. -Justin R.

[Dovecot] got too little data ??
by Benoit Branciard 12 Dec '07

12 Dec '07

I just switched in a hurry one of our mailbox servers from UW-imapd to Dovecot in an attempt to address performance and stability problems. This server hosts ~5500 accounts, ~2000 are daily used, ~600 simultaneous IMAP connexions in rush hours, and lots of POP ones. Some accounts may be accessed simultaneously with IMAP and POP. The system is : - Debian Sarge (x86 with amd64 kernel) - MBOX files mailboxes - indexes migrated out of filesystem quotas - Sendmail MTA - Procmail local delivery agent (not easily replaceable due to extensive use of procmailrc filters) - Both Procmail and Dovecot use [dotlock, fcntl] as mailbox locking scheme - No other processes have access to mailboxes in normal use - Dovecot 1.0.8 hand-compiled from tarball The good new is that it seems to perform better than UW-imapd. The bad new is that we get lots or errors like this in log: IMAP(username): FETCH for mailbox INBOX UID 23862 got too little data: 3186 vs 3206 Such "accidents" happen about 4-5 times a day, and does not correct themselves, even with a mailbox expunge or reopen. However manual deletion of the faulty mailbox index seems to clear the problem, until another one occurs. On such errors some mail clients (Thunderbird) retry operation in infinite loop, so log gets really cluttered. In imap-fetch-body.c it is stated : "We shouldn't really ever get here. One reason is if mail was deleted from NFS server while we were reading it. Another is some temporary disk error." Both reasons do not seem to apply in our case: mail partition is not NFS-mounted, and disks (a RAID5 array) seem healthy. Furthermore, affected accounts are not over quota. So may we have found a bug ? Or may we have a locking problem ? Or an index handling one ? I tried to disable mbox_lazy_writes without success. I will try to disable disk indexes totally, which should help since problems seem index-related; but performance may suffer. Any clues appreciated...

I know I'm late reporting this but 1.08 seems really slow. It seems like it is as slow as some of the early RCs were. Wish I had more info. Using Maildir format.

[Dovecot] 1.0.8 with quota 1.0.8 patch - undefined symbol: quota_set

(it is a patch for Postfix 2.4.nn) It would seem that the type of fishing expedition you mention would fall into the bit described below (lots of errors). While it will not directly solve the "out of resources" Dovecot problem, it may limit the up-front damage, followed with a CRON script running every twenty minutes or so that scans the last line of the mail log for the 'too many files open' error and upon finding it runs a version of the killall imap-login processes. ftp://postfix.mirrors.pair.com/index.html Postfix 2.4 patch (PGP signature ) to add stress-adaptive behavior to the SMTP server. When some mail flood keeps all server ports busy, this feature can be used to quickly drop connections from clients that make errors, and to reduce the time that Postfix waits for a client command. This may delay some legitimate deliveries, but it will allow you to still keep some mail flowing. After the mail flood ends, Postfix reverts to its normal behavior.
