[Dovecot] Dovecot 1.0.7 domain variable
by elliott＠n.localhost 13 May '09

13 May '09

Hi all, Thanks in advance for any help! I'm trying to configure Dovecot to pull emails from Postfix virtual mailbox domain Maildirs under /var/mail/vhosts/<domain>/<username>. I've set mail_location as such in dovecot.conf: mail_location = maildir:/var/mail/vhosts/%d/%n but from debug output I see the domain is blank: dovecot: May 10 20:49:25 Info: IMAP(elliott): maildir: data=/var/mail/vhosts//elliott I've set elliott(a)n.0o0.bz as my username in Outlook so it is sending the domain (and changed auth_username_format to "auth_username_format = %n" so authentication works fine) Why is %d blank here? Anything else to check?? I'm at a loss. Thanks! -elliott-

[Dovecot] New messages notification - (IMAP PUSH?)
by Proskurin Kirill 13 May '09

13 May '09

Hello all. I have strange problem. As I understand IMAP use server2client command to tell what new email is arrived. So - all was good, but few weeks ago I notice what my thunderbird not show new messages. I think it was local problem(I switch distro what day) but soon my email clients what uses mostly Outlook-2007-SP1 start to confirm this problem. What can it be and how can I fix it? I use Dovecot on FreeBSD-7.1 #pkg_info | grep dovecot dovecot-1.1.11 dovecot-managesieve-0.10.5 dovecot-sieve-1.1.6 #dovecot -n # 1.1.11: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.1-RELEASE-p3 i386 ufs base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-debug.log protocols: imap imaps pop3 pop3s managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000 ssl_ca_file: /usr/local/etc/certs/GlobalSignCA.crt ssl_cert_file: /usr/local/etc/certs/fxclub_org.crt ssl_key_file: /usr/local/etc/certs/fxclub_org.key ssl_cipher_list: ALL:!LOW:!SSLv2 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 login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_greeting_capability(managesieve): no login_process_size: 128 login_processes_count: 20 login_max_processes_count: 512 mail_max_userip_connections(default): 256 mail_max_userip_connections(imap): 256 mail_max_userip_connections(pop3): 20 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_gid: 0 mail_privileged_group: mail mail_uid: dmail mail_gid: dmail mail_location(default): maildir:/var/spool/dovecot/domains/%d/%n/ mail_location(imap): maildir:/var/spool/dovecot/domains/%d/%n/ mail_location(pop3): maildir:/var/spool/dovecot/domains/%d/%n/ mail_location(managesieve): mail_debug: yes 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_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_process_size: 512 mail_plugins(default): quota imap_quota autocreate mail_plugins(imap): quota imap_quota autocreate mail_plugins(pop3): quota mail_plugins(managesieve): 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 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): delay-newmail tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): % sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login user: dovecot-auth username_format: %Lu verbose: yes worker_max_count: 100 passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: exim master: path: /var/run/dovecot/auth-master mode: 384 user: dmail plugin: quota: maildir quota_rule: *:storage=1024M quota_rule2: Trash:storage=1256M quota_rule3: SPAM:ignore quota_warning: storage=80%% /usr/local/bin/quota-warning.sh 80 quota_warning2: storage=95%% /usr/local/bin/quota-warning.sh 95 autocreate: Trash autocreate2: Sent autocreate3: Spam autosubscribe: Trash autosubscribe2: Sent autosubscribe3: Spam -- Best regards, Proskurin Kirill

[Dovecot] Dovecot shared quota with Maildir
by Jorgen Lundman 13 May '09

13 May '09

Hello list, We are in the process of exploring the idea of moving from UFS with fs-quota to using softquotas in Dovecot (probably Maildir type, stored in LDAP, all ontop of NFS). I have it setup, and it works rather well so far. But there is one situation we can currently support, which I can not see a solution for with soft-quotas. Generally customers get 1 email, with 1 quota. But it is also possible for customers to get 1 quota, but create multiple mail accounts, all sharing the same quota. This is done by using the same UID for each account when using fs-quota. (It is not that each account gets a fraction of the quota, but that all accounts add up to the one quota). Is this still possible to do with soft-quotas. To share one set. Dovecot would have to go count files in multiple mail-directories so I would guess no.

[Dovecot] dovecot bug (maybe)
by Fernando Bertasso 12 May '09

12 May '09

I believe that dovecot is doing something strange, when it founds a 'corrupted' multipart and using fetch body. Look what I figured out: 1) Sent a message from squirrelmail (it wrongly drop the last \n from epilogue): ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n <--------(squirrelmail didn´t insert an additional \n). ------=_20090512171902_78105-- 2) Sent a correct message, inserting the last '\n': ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105-- 3) Compress both messages 4) Request the messages using: A004 UID FETCH 1 (FLAGS BODYSTRUCTURE) (the correct message): 127.000.000.001.00143-127.000.000.001.35604: * 1 FETCH (UID 1 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *3 1*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171853_50085") NIL NIL NIL)) A004 OK Fetch completed. 5) Request the broken message: 127.000.000.001.00143-127.000.000.001.43679: * 2 FETCH (UID 2 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *1 0*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171902_78105") NIL NIL NIL)) A004 OK Fetch completed. >From RFC the red numbers mean: size body, number of line for the body. This makes sense, because stripping the 'control' chars from first message, size and number of lines match. But in the second message, the line number is 0 - this does not make sense. You need to test this using telnet, because outlook and thunderbird did not follow this way, they use body.peek. What do you think? Fernando

[Dovecot] user_attrs seems not to set 'mail'.
by ian＠comtek.co.uk 12 May '09

12 May '09

Hi, I am using Dovecot 1.1.13 (from a Debian package). I was having problems using user_attrs to set 'mail' and 'home'. Initially I tried: user_attrs = uid=mail=maildir:/var/mail/virtual/users/%$/Maildir/,uid=home=/var/mail/virtual/users/%$/ This appeared to set 'home' but not 'mail'. In the debug lot I see: May 12 15:24:40 alpha dovecot: auth(default): ldap(X(a)Y,10.4.4.113): user search: base=ou=users,dc=Y scope=subtree filter=(& (mail=X@Y) (|(accountStatus=active) (accountStatus=migrate)) ) fields=uid,uid May 12 15:24:40 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): result: uid(home=/var/mail/virtual/users/%$/)=/var/mail/virtual/users/uid/ May 12 15:24:40 alpha dovecot: auth(default): master out: USER 30688 X@Y home=/var/mail/virtual/users/uid/ Note that 'home' seems to be set on the last line, but not 'mail'. I was hoping to see 'mail=/var/mail/virtual/users/uid/Maildir/'. Next I tried: user_attrs = =mail=maildir:~/Maildir/,uid=home=/var/mail/virtual/users/%$/ Now I see: May 12 15:31:28 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): user search: base=ou=users,dc=Y scope=subtree filter=(& (mail=X@Y) (|(accountStatus=active) (accountStatus=migrate)) ) fields=uid May 12 15:31:28 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): result: uid(home=/var/mail/virtual/users/%$/)=/var/mail/virtual/users/uid/ May 12 15:31:28 alpha dovecot: auth(default): master out: USER 30712 X@Y home=/var/mail/virtual/users/uid/ mail=maildir:~/Maildir/ Now both 'home' and 'mail' are set, which is what I want. This means the following lines are not synonymous: user_attrs = uid=mail=maildir:/var/mail/virtual/users/%$/Maildir/,uid=home=/var/mail/virtual/users/%$/ user_attrs = =mail=maildir:~/Maildir/,uid=home=/var/mail/virtual/users/%$/ Either I misunderstand the documentation for user_attrs or there is a bug. Assuming the former, can somebody please explain what I am doing wrong? Thanks, Ian

[Dovecot] Dovecot auth user lookup patch updated for maildrop 2.1.0
by mr.maX 12 May '09

12 May '09

Hi, an updated version of my patch for maildrop that extends it with the ability to perform user lookups against Dovecot's database made against the latest version of maildrop 2.1.0 can be downloaded from the following location: http://www.max.rs/ozone/maildrop-2.1.0-dovecotauth.patch.txt The patch has just been redone in order to apply cleanly without fuzz and to apply properly against one file that was changed in the latest version of maildrop. There have been no other changes compared to the initial version of the patch. For more information, take a look at my previous post to the Dovecot's mailing list at: http://www.dovecot.org/list/dovecot/2009-April/039121.html -- Best Regards, Marko Njezic - mr.maX @ MAX Interactive corp.

[Dovecot] Fail2Ban and the Dovecot log
by Lou Duchez 12 May '09

12 May '09

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there will be a problem: "In order for a log line to match your failregex, it actually has to match in two parts: the beginning of the line has to match a timestamp pattern or regex, and the remainder of the line has to match your failregex.". So in other words, Fail2Ban expects that each line of the log will start with a timestamp. Thanks all! Dovecot rocks.

[Dovecot] Sieve & Regex
by Peregrino "Pipino" Tuc 12 May '09

12 May '09

Hi all I'm trying to create a new sieve rule. What I would like to do is catch "From" addresses that are equal to the rightpart (hostname) of a message-id. For example: Message-ID: <000d01c9d23a$941a7db0$6400a8c0@upwabm> From: "Leanne Crabtree" <upwabm(a)blomberg-co.com> I would like to catch this mail, because it has "upwabm" on the right part of the message-id and "upwabm" on the left part of the sender address. I've done this, but with no success. The error reported is: "Invalid preceding regular expression" on line with the second regex with ${1} More over I would like to add an header with the result of regex, an header like this: "X-MyHeader" "${1}" but it does not work. This is an extract of our sieve: --- require ["regex"]; if header :regex "Message-ID" "^.*(a)(.*)>$" { if header :regex "From" ".*<${1}@.*>$" { addheader "X-MyHeader" "${1}" } } ---

[Dovecot] Quota over NFS
by Flavio Costa 11 May '09

11 May '09

Hey, I've been strugling to get quota working on my enviroment. I have one storage server that exports the 'home' dir. My mail server mounts the exported 'home' server at '/home' # dovecot --version > 1.1.14 I'm also running Postfix and using Dovecot/LDA as MDA so that we can use the Dovecot's Quota plugin. The thing is that if the user has exceeded it's quota the LDA detects it and I get a response from postmaster warning me that the INBOX is full. But through IMAP, if I issue : > C: 1 GETQUOTAROOT INBOX > S: * QUOTAROOT INBOX "" > S: 1 OK Getquota complete > > There's no: > * QUOTA "" (STORAGE 10 512) > > I've tried using this plugin for Thunderbird: https://addons.mozilla.org/pt-BR/thunderbird/addon/881 And also tested issuing commands by hand. Running 'quota' on the console works just fine, that means that rpc.rquotad is running smoothly. # quota USER > Disk quotas for user coutinho (uid 1191): > Filesystem blocks quota limit grace files quota limit > grace > home.mail:/home > 166264* 102400 153600 3013 0 > 0 > Thanks in advance for you help. -- Flávio Coutinho da Costa

[Dovecot] dovecot weird bug
by Fernando Bertasso 11 May '09

11 May '09

Hi, We have a weird bug happening in our dovecot installation. When I send html emails from many clients and compress them, there are no problem. They are opened and correctly formated. When I send an email from Squirrelmail and compress it, dovecot exits with no errors (there are no coredumps or seg fault - dovecot just exits). But the weird is, it just happens when squirrelmail opens an email (compressed) that was sent by squirrelmail (all other clients can open it and squirrel can open all other emails sent by other clients). (Try with this message - compressing too - it occurs with me).

[Dovecot] NTLM configuration
by Cédric Laruelle 11 May '09

11 May '09

Hi again everybody ! Im still stuck with the dovecot ntlm authentication I configured dovecot to use winbind, and I would like winbind to authenticate against samba (samba, winbind and dovecot are running on the same box).

[Dovecot] dovecot weird bug
by Fernando Bertasso 11 May '09

11 May '09

I found the bug, there are two errors: 1) Squirrelmail is wrongly formating multipart/alternative messages. Look here: ------=_20090510163738_24160 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit a<br /> *<------ HERE* ------=_20090510163738_24160-- All other clients insert an '\n' here, but squirrelmail. 2) When this king of message (above) is compressed (in order to use zlib plugin), dovecot dies. Best Regards, Fernando

[Dovecot] Dovecot not accepting connections
by Jim 11 May '09

11 May '09

Hi, new user here, trying to track down an issue. Sometimes, after starting dovecot, I'll attempt to check mail and will not be able to get a connection to my server. I'll kill dovecot, restart it, and usually it will begin working. When I first ran into this, I first tried auth_debug=yes, restarted dovecot, and had no problems. I'd turn set auth_debug=no, restart dovecot, and would be unable to check mail. After a time I determined that setting the debug wasn't really effecting anything, it was just hit or miss if I'd be able to get a connection. Once I was able to get a connection, things were fine until dovecot started again. Nothing unusual in the logs, if it works or not, I'll just see this at startup: Mar 25 21:34:48 mail-web-server dovecot[664]: dovecot v1.1.13 starting up (core dumps disabled) Mar 25 21:34:48 mail-web-server dovecot[664]: auth-worker(default): mysql: Connected to localhost (postfix) If debug is on and connections aren't being accepted, I never see anything in the logs. Below is my config. Running on OS X 10.5.6.

[Dovecot] Degeneration of CPU Performance
by Thiago Monaco Papageorgiou 11 May '09

11 May '09

Hello everybody! We have a interesting issue about dovecot behavior here. First, the scenario: We have 2 server running with the same load, one with our old pop3 solution (out of date) and other with Dovecot. We realized that dovecot are comsuming more CPU, and this consumption is growing day by day. When we starts dovecot, it runs between 40%-45% of CPU consumption and our old solution runs on 30-35%. This is quite acceptable, so no problem here. The problem is one day after it jumps to 45%-55% of cpu comsunption while the old pop3 solution runs on the same CPU consumption of one day before (30%-35). I attached a graph with this information. In this graph the green line is dovecot CPU consumption and the blue line is the old solution. In this graph we restart dovecot at monday morning. This restart is noticed as a big fall of CPU consumption(green line) in the graph. After that, it stay between 40%-45%, one day after it runs on 45%-55% and next day, it reaches 50%-60%! You can notice that the blue line (old pop3 solution) runs with the same behavior, so we have the same load. We have other monitoring informations that confirm it. I looked for some bugs about this, but I didn't find anything. The question is: Is there any dovecot problem or wrong configuration that could cause this degeneration of CPU performance? Any sugestion about what can be the cause of this? I attached dovecot -n output. Two important information: we store the mailboxes in NFS and we are only using pop3 protocol.

[Dovecot] Unit testing
by Timo Sirainen 09 May '09

09 May '09

Unit testing is slowly going forward in Dovecot. In v2.0 tree all the unit tests are now run when you do "make check". They're also run on "make distcheck", which is what I use when building releases or nightly snapshots. So as soon as I start building nightly v2.0 snapshots I should start getting mails every night if the unit tests fail. And I can no longer make a release if a unit test fails. (Unit tests never get run manually - I once fixed a unit test that had been failing for months.) Besides that, I started trying to add unit tests to lib-index. After some hours of refactoring the code I finally managed to get mail-transaction-log-view and mail-index-transaction to a condition where unit tests could be added to them without too much pain. I didn't really add that many unit tests there yet though. I'll probably slowly continue adding more tests and refactoring the code more to allow more unit tests, but if anyone else finds they have nothing better to do, now's a good time to add more tests :) Especially lib/, lib-mail/ and lib-imap/ should already be easily testable and they're missing a lot of tests.

[Dovecot] dovecot slowing down
by P.A 08 May '09

08 May '09

Hi, not really a dovecot issue but, im running dovecot 1.0.10 with no issues for awhile now J. However I ran into an issue today where postfix didn't have enough processes to handle incoming smtp connections. This for whatever reason was causing pop/imap (dovecot) to take a long time to respond on the appropriate port. After looking at server and finding nothing wrong I stopped postfix which got rid of the delay on port 110/143. I then turned on postfix again and saw the delay for port 25/110/143. What I then did was adjust/increase the default_process_limit in postfix which took care of the problem. Question is why would not enough processes in postfix slow other services down like dovecot 110/143? There was plenty of bandwith/mem/cpu left.

[Dovecot] mailutil?
by Timo Sirainen 08 May '09

08 May '09

dbox format needs at least two tools: 1. Expunging only marks the message having refcount=0. The actual disk space is freed only after calling a tool pointing to the user's dbox dir. 2. Ability to force index resync/rebuild in case it doesn't figure out itself that there's something wrong. I'm starting to think about building a more generic mailutil tool, maybe something similar to what UW-IMAP has. So two questions: - What should the tool be called? Probably not mailutil to avoid confusion. doveutil? dovemail? dovetool? mailtool? - Is there any functionality you'd like it to do?

[Dovecot] Imap notifications in IDLE
by Jarosław Przybyłowicz 07 May '09

07 May '09

Hi, could you please tell me if there is a way, to make dovecot notify my mail client of new messages in inbox subfolders? I'm using fdm to fetch mails into maildir and proper subfolders. So far, when idleing mozilla gets a notification when new message arrives in INBOX, but if mail is fetched into other folder I have to click on it to see if there is a new message. I've checked thunderbird imap log to check if this is dovecot or TB issue. Is there any way to force dovecot to monitor other folders? Regards, V

[Dovecot] authentication to IMAP
by punit_j 07 May '09

HI All, Is there a way to do admin authentication for a normal user in dovecot IMAP ? I have a user using PAM to store password in /etc/shadow file. I need to authenticate the user in IMAP using that password. I tried using : - I tried all combinations as below [root@mail ~]# cat /etc/shadow| grep -i ajay ajay.lal:CM730q8foSA9A:13545:0:99999:7::: [root@mail ~]# telnet 0 143 Trying 0.0.0.0...

My dovecot server does PLAIN authentication as can auth_mechanisms = plain Is there a way to do PLAIN auth with crypt password or any means of doing admin authentication on behalf of normal user ?
