[Dovecot] Multiple ssl certificates
by Wojciech Matys 17 Apr '08

17 Apr '08

Hello, I wonder if there is some possibility to force dovecot to use more than one ssl certificate. I would like to use a few certficates: one per IP We are hosting many different domains and I had to use stunnel to ensure encrypted connection for our clients using different certificates. But stunnel isn't a good solution and sometimes I need to restart stunnels because of some of it's processes hangs - after some improvements like setting ulimit it is better now but still it is not a permanent soulution. I would like to use is: 1.1.1.1 - certificate nr1 2.2.2.2 - certificate nr2 ..... Any suggestion?

[Dovecot] pop3 & imap
by Tommy 17 Apr '08

17 Apr '08

Hi, I use dovecot as pop3 and imap(squirrelmail) server. When I create a folder through webmail and set some sieve rules(fileinto for example), messages will be delivered to that folder by lda, but will not be visibe for pop clients. Is it possible to download these messages ? (Dovecot 1.0, debian etch) regards

Re: [Dovecot] sa learning from an imap spam folder
by frank.kintrup＠fkware.de 11 Apr '08

11 Apr '08

This is my approach, stored in /etc/cron.hourly. It's very new, so I'm still testing it. The goal is to learn HAM massages only if they are a day old, so that I can manually remove SPAM that slipped through. Mails tagged from Spamassassin are sorted automatically into the "Junk.Spam" mailbox and learned after 12 hours. I manually move any missed SPAM into the .Junk mailbox, so I'm sure there are no wrongly tagged messages there, so I can learn those messages as soon as they are found by cron. /etc/cron.hourly/sa-learn: #!/bin/sh umask 022 # Learn HAM messages which were roughly received between 24 and 25 hours ago find \ /var/vmail/fkware.de/frank.kintrup/Maildir/ \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Junk*' -prune -o \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Sent' -prune -o \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Trash' -prune -o \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Draft' -prune -o \ -iname '*server.fkware.de*' -type f -mmin +1435 -mmin -1505 \ -execdir sa-learn --username=vmail --no-sync --ham {} \; \ /dev/nul 2>/dev/nul # Learn and delete SPAM messages which were manually moved to the Junk folder find \ /var/vmail/fkware.de/frank.kintrup/Maildir/.Junk/ \ -iname '*server.fkware.de*' -type f \ -execdir sa-learn --username=vmail --no-sync --spam {} \; \ -execdir rm {} \; \ >/dev/nul 2>/dev/nul # Learn and delete SPAM messages which were received more than 12 hours ago # and automatically put into the Junk.Spam folder find \ /var/vmail/fkware.de/frank.kintrup/Maildir/.Junk.Spam/ \ -iname '*server.fkware.de*' -type f -mmin +720 \ -execdir sa-learn --username=vmail --no-sync --spam {} \; \ -execdir rm {} \; \ >/dev/nul 2>/dev/nul sa-learn --username=vmail --sync >/dev/nul exit 0

[Dovecot] Sieve Frustrations
by Shawn 11 Apr '08

11 Apr '08

I'm soooo close, but this last little thing is eluding me... I have the following Sieve rule in my global sieve rule: require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; stop; } This isn't firing. The .Junk folder exists under the user directories, but messages that have the X-Spam-Flag set are still going into INBOX. My personal Sieve rules are firing properly (now), so I know Sieve is operational. Just the global rule isn't being applied. If it helps, I set up my server according http://workaround.org/articles/ispmail-etch/ - but on a Ubuntu Gutsy server with only a few minor deviations from that article. My protocol lda section of dovecot.conf has this: log_path = /home/vmail/dovecot-deliver.log global_script_path = /home/vmail/globalsieverc I don't see any messages in dovecot-deliver.log that says there are problems with Sieve. The above rule is in /home/vmail/globalsieverc as mentioned here. This was working once - but when I had it going into the "spam" folder. I changed the folder name to match what ThunderBird sets up automagically for it's junk controls. But like I say, the directory does exist. So, I'm a little stumped. Any suggestions on where I can look to sort this out? If it helps, I've attached my dovecot conf (via dovecot -n) below. Thank you for your time!

[Dovecot] Procmail died with Signal 11
by Johannes Grimm 10 Apr '08

10 Apr '08

Hi to all out there, i know this is not the right mailinglist for this issue, but i?m hoping to get maybe here an answer to my problem. i have succesfully migrated 12.000 mailboxes on a debaian with washington imap to maildir on sles10 with dovecot. although i had some post-converting work to do, i can say that almost everything went fine. but there is one problem with my LDA. When postfix is about to deliver a lot of mail (user-db is ldap) procmail dies with signal 11. here is the error log: Apr 3 08:19:17 mailvirtuell postfix/local[22367]: E42EF33A96: to=<root(a)fh-rosenheim.de>, relay=local, delay=17, delays=0.08/0.11/0/17, dsn=5.3.0, status=bounced (Command died with signal 11: "IFS=` `&& exec /usr/bin/procmail || exit 75 #Ja". Command output: procmail: Exceeded LINEBUF ) I googled the whole inet for this problem and found a lot, but no solution seems to fit my problem. most articles point on this parameter for procmailrc "Linebuf". i found out that the default value is 2048k for message header reading. i doubled this value, with no effect. but i guess that a 4kb message header space must be enough to deal with. one hint last: starting value for ldap timeout was 10 secs. with this value the log went crazy like the above log-snip. i changed the timeout to 300 secs and thougt that was the trick, but there are still some process wich are diying after all. i?m using postfix 2.5.1, procmail 3.22, dovecot 1.0.13, with sophos and amavis. i would be really grateful for any ideas. best regards Johannes Grimm -- ============================================================== Hochschule für angewandte Wissenschaften - Fachhochschule Rosenheim University of Applied Sciences Rechenzentrum Johannes Grimm Hochschulstr.1 D-83024 Rosenheim Tel: +49-8031/805-229 Fax: +49-8031/805-223 http://www.fh-rosenheim.de/ johannes.grimm(a)fh-rosenheim.de ==============================================================

[Dovecot] Delete old mails and refresh quota
by Nicolas Letellier 09 Apr '08

09 Apr '08

Hello. I use dovecot 1.0.13. So, I can't use expire plugin (require dovecot 1.1+). For delete old mails in Junk mailboxe, I use a cron: find /var/mail/vmails/ -regex '.*Junk/cur/.*' -ctime +30 -delete It works. However, quota is not refreshed. If my quota is to 90% and I delete 85% of my mails, quota still 90%, not 5%. I must delete my maildirsize after this cron. Do you have another solution to actualisize my maildirsize after a delete of mail? Thanks! - Nicolas.

[Dovecot] Newbie Sieve Problems
by Shawn 09 Apr '08

09 Apr '08

I had a nice long email written out describing my problem in detail. Between that, the list archives, and double-checking before posting, I'm happy to say my issue seems to be fixed. How's that for service from a mailing list? Helped me fix a problem before I have ever posted to it (this is my first post to this list). The issue was a faulty rule. Using a redirect to a folder rather than a fileinto. Guess it was still sorta valid though cuz I did run it through a sieve rule checker. Thanks list! Shawn

Hello, is there some way how to disable temporarily account or access to files. I need to backup with tar, but there is problem when tar is reading and some file changed (with --ignore-failed-read it continues but archive is not created and without --ignore-failed-read it fails). Some accounts are huge ;( Need something like qmail sticky bit or world writable directory - qmail is not delivering when one of above conditions hits. Thank you for helping me. -- Lampa

[Dovecot] dovecot and postfix virtual mailbox domains
by Dave 08 Apr '08

08 Apr '08

Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username, there's a maildir under that. In this case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account and being completely virtual. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd I'd appreciate any pointers. I think i am close, but am not seeing it. Thanks. Dave.

[Dovecot] feature request: deny IP address via database
by Dave McGuire 08 Apr '08

08 Apr '08

Hey folks. One feature I'd really like to see in dovecot is the ability to point it at a database (with a configurable query) and have it allow or deny a connection based on looking up the source IP address in that database. I run Postfix, and I've got it configured to use a database server for its smtpd_client_restrictions checks. Ideally I'd like to point dovecot at the same database table. I have external tools that maintain that table. I was thinking of writing it myself, but I'm running 1.0.10; I'd assume that any such modifications would need to be rewritten for 1.1. Then I got to thinking that such functionality would likely be useful to people other than just me, so.. Thoughts? -Dave -- Dave McGuire Port Charlotte, FL

I understand that the behaviour requested is similar to that of allow_nets (http://wiki.dovecot.org/PasswordDatabase/ExtraFields/AllowNets) but modified to explicitly deny some IPs (individually or in the range form). If so, probably some of the work should be already done. Sorry, I do not have the programming abilities enough to face this. Incidentally, I would like to notice that I opened a thread a few days ago regarding allow_nets and database (Bill's request needs to make use of an external database too) because I am not able to make allow_nets work properly when using an external DB *and IP ranges*. Maybe Bill would like to block single IPs so this bug? wold not apply to his case if an extension or adaptation of allow_nets is done. (My request, in case someone out there is curious: "Allow_nets + MySQL failing when using range notation") Regards, Javier

[Dovecot] A little assistance with Sieve
by cam＠ellisonpsychology.ca 07 Apr '08

07 Apr '08

With all the mess that my email has become, it makes sense for me to try to make use of Sieve, but I'm having quite the time finding out how to make it work. I'm running 1.0.13 on a Debian machine. Sieve appears to be compiled with it. I can access managesieve, and I have set up dovecot.conf with lda. I do not get a NO response when I PUTSCRIPI, but LISTSCRIPTS produces no result, so I assume it's not working properly, though if I try with a non-existent script I get an error message. Questions: 1. Is anyone else seeing this, or am I doing something wrong? 2. I have seen through Googling some dovecot.conf examples that suggest I should be using managesieve instead of lda (or in addition? - it's not clear), as in protocol managesieve { ...

[Dovecot] Problem with dovecot under Vmware Server
by Marvin Raab 06 Apr '08

06 Apr '08

Hi all, Recently installed dovecot and postfix under Fedora8 and it works great. Then I installed both postfix and dovecot under VMWare Server (different machine) copying the same configuration files but changing the hostname and domain as appropriate. When testing the installation using: telnet hostname 143, I receive * OK Dovecot ready But when I telnet on port 25, I receive: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Instead of: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 mail.kickspam.net ESMTP Postfix Naturally, I cannot send email. Outlook responds with Server timeout. I've rebooted and restarted services. I've checked poermissions and postfix master.cf How can I troubleshoot or does anyone have a quick answer? Thanks!

[Dovecot] Broken Debian package
by Thing 06 Apr '08

06 Apr '08

Hi, I have run Dovecot via Debian for some years but in the last few weeks something has broken....I have been upgrading Debian but today rebooted it to try and sort out a failed DLT....now I find dovecot is non-functional.... So, Where to look for faults please? ie logs? can I make dovecot verbose? Thunderbird if telling me Dovecot is not imap4 compliant........and I cannot connect to it... I have tried re-installing Dovecot but the Debian package contains no dovecot.conf....so I have dovecot imap-d and dovecot common installed but no config. So I copied back the config files from a safe location.... When I start up I get, hermes:/var/log# tail dovecot dovecot: 2008-04-06 11:32:32 Info: Dovecot v1.0.rc15 starting up hermes:/var/log# So trying to connect, tail -f (on /var/log/dovecot), dovecot: 2008-04-06 11:57:34 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:34 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:34 Error: child 20048 (imap) killed with signal 6 dovecot: 2008-04-06 11:57:34 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:34 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:34 Error: child 20050 (imap) killed with signal 6 dovecot: 2008-04-06 11:57:34 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:34 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:34 Error: child 20052 (imap) killed with signal 6 dovecot: 2008-04-06 11:57:35 Info: imap-login: Login: user=<phoebe>, method=PLAIN, rip=192.168.1.102, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:35 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:35 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:35 Error: child 20062 (imap) killed with signal 6 squirrelmail is also now dead....

[Dovecot] Leave mail on server leads to dup messages
by Arliss Jameson 05 Apr '08

05 Apr '08

Hi. I'm a dovecot newbie. I've set my pop client to leave messages on the server for 7 days. I'm downloading the same messages over and over as dovecot appears to be overwriting X-UID's in the mbox's. I can't think of any other program on the system that might write to the mbox other than postfix (and that program doesn't appear to be writing X-UID). My setup has one user (system account: vmail) that owns all mbox's. The user_query always returns vmail's home, uid and gid (you can view the SELECT's in the log snippet below).I have a total of four pop3 virtual mbox's. The example below illustrates what happens to one of them (though this problem extends to the others as well). Here's what happens: 1) Start with an empty mbox 2) Start dovecot 3) Download mail (received one email) cat mbox | egrep "X-UID:" X-UID: 789 4) Download mail again (received another email) cat mbox | egrep "X-UID:" X-UID: 789 X-UID: 790 5) Download mail once more (received three spam emails) cat mbox | egrep "X-UID:" X-UID: 811 X-UID: 812 X-UID: 813 X-UID: 814 X-UID: 815 What the?! 6) Check log dovecot: Apr 04 13:51:42 Info: auth(default): new auth connection: pid=12843 dovecot: Apr 04 13:51:42 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=76.158.191.23 rip=44.156.77.13 resp=<hidden> dovecot: Apr 04 13:51:42 Info: auth-worker(default): sql(imacrawler(a)searchingforaddressestospam.com,44.156.77.13): query: SELECT CONCAT(username, '@', domain) AS user, password FROM (SELECT vuser.username, vuser.password, vdomain.name AS domain FROM vuser LEFT JOIN vdomain ON vuser.vdomain_id=vdomain.id) a WHERE a.username='imacrawler' AND a.domain='searchingforaddressestospam.com' dovecot: Apr 04 13:51:42 Info: auth(default): client out: OK 1 user=imacrawler(a)searchingforaddressestospam.com dovecot: Apr 04 13:51:42 Info: auth(default): master in: REQUEST 7 12837 1 dovecot: Apr 04 13:51:42 Info: auth-worker(default): sql(imacrawler(a)searchingforaddressestospam.com,44.156.77.13): SELECT '/vmail' AS home, CONCAT('mbox:~/mail:INBOX=/var/spool/vmail/', TRIM('searchingforaddressestospam.com'), '/', TRIM('imacrawler')) AS mail, 103 AS uid, 104 AS gid dovecot: Apr 04 13:51:42 Info: auth(default): master out: USER 7 imacrawler(a)searchingforaddressestospam.com home=/vmail mail=mbox:~/mail:INBOX=/var/spool/vmail/searchingforaddressestospam.com/ima… uid=103 gid=104 dovecot: Apr 04 13:51:42 Error: POP3(imacrawler(a)searchingforaddressestospam.com): mbox sync: Expunged message reappeared in mailbox /var/spool/vmail/searchingforaddressestospam.com/imacrawler (UID 789 < 796, seq=1, idx_msgs=0) dovecot: Apr 04 13:51:42 Info: pop3-login: Login: user=<imacrawler(a)searchingforaddressestospam.com>, method=PLAIN, rip=44.156.77.13, lip=76.158.191.23 dovecot: Apr 04 13:51:42 Error: POP3(imacrawler(a)searchingforaddressestospam.com): mbox sync: UID inserted in the middle of mailbox /var/spool/vmail/searchingforaddressestospam.com/imacrawler (796 > 789, seq=1, idx_msgs=5) dovecot: Apr 04 13:51:42 Error: POP3(imacrawler(a)searchingforaddressestospam.com): mbox sync: UID inserted in the middle of mailbox /var/spool/vmail/searchingforaddressestospam.com/imacrawler (801 > 789, seq=1, idx_msgs=5) dovecot: Apr 04 13:51:43 Error: POP3(imacrawler(a)searchingforaddressestospam.com): mbox sync: UID inserted in the middle of mailbox /var/spool/vmail/searchingforaddressestospam.com/imacrawler (806 > 789, seq=1, idx_msgs=5) dovecot: Apr 04 13:51:43 Info: POP3(imacrawler(a)searchingforaddressestospam.com): Disconnected: Logged out top=0/0, retr=5/9032, del=0/5, size=8947 I have no idea why it's complaining about 796 or where that number even came from.

[Dovecot] Dovecot and stale nfs-locks hanging processes
by Søren Schrøder 05 Apr '08

05 Apr '08

Greetings dovecot mailing list. I have implemented a relatively big dovecot setup (250k users) and overall I am very pleased with dovecot functionality and performance. Setup description: * dovecot 1.0.x * FreeBSD 6.3 * Postfix (using dovecot deliver as LDA). * OpenLdap backend * Storage is NFS (Clariion EMC NFSd for Maildir, and FreeBSD NFSd for Indexes). * Locking is fcntl using RPC.lockd. * Users are accessing mail using POP3 and IMAP (IMAP mainly via Squirrelmail, but also direct) * 3 frontends for POP/SMTP and 2 frontends for IMAP (webmail). Round Robin DNS My problem: I am having issues where POP3, IMAP and DELIVER processes gets stuck, apparently waiting for device. fstat shows: bash# fstat -p 93522 USER CMD PID FD MOUNT INUM MODE SZ|DV R/W 302870 pop3 93522 root / 2 drwxr-xr-x 512 r 302870 pop3 93522 wd /home/mnt5 51592 drwxr-xr-x 80 r 302870 pop3 93522 text /usr 121619 -r-xr-xr-x 436616 r 302870 pop3 93522 0* internet stream tcp 302870 pop3 93522 1* internet stream tcp 302870 pop3 93522 2* pipe c778aa48 <-> c778a990 0 rw 302870 pop3 93522 3 /dev 24 crw-rw-rw- random r 302870 pop3 93522 5* pipe ce440b28 <-> ce440be0 0 rw 302870 pop3 93522 6* pipe ce440be0 <-> ce440b28 0 rw 302870 pop3 93522 7 /home/mnt5 9010290 -rw------- 1493 rw 302870 pop3 93522 8 - - bad - 302870 pop3 93522 9 - - bad - 302870 pop3 93522 10 - - bad And the inode in question on /home/mnt5 is a dot-nfs file, indicating stale lock: bash# ls -li | grep 9010290 9010290 -rw------- 1 302870 42 1493 Apr 3 18:05 .nfs.0668c236.6d524.4 ktrace on the pid shows absolutely no activity. The pop3 process is un-killable, and I end up stacking up pop3 processes from the user, as well as deliver to the user. Not healthy.. I was under the impression that POP3 would exit when a lock is set, preventing more than one pop3 processes pr. user, but it doesn't seem to be the case. Stopping dovecot entirely, leaves these stale pop3/imap/deliver processes hanging, even with shutdown_clients = yes The windows-problem-solution (reboot) seems to be the only way to get rid of the locked processes. So: Has anyone else observed this behavior, and eventually found the magic cure ? I wonder if there was a way to implement a "max wall-clock time" per dovecot process type (i.e.. terminate process after for example 120 sec. delivery, 600 sec pop3 etc...), as a crude "garbage-collector". Any hints/suggestions is welcome. -- Søren Schrøder

[Dovecot] LDAP auth_bind hangs and times out
by Jack McKinney 04 Apr '08

04 Apr '08

I have _almost_ got Dovecot working! One little snag... My users login using their email address as username. Each domain has their own LDAP subtree. Each user has an entry in the ou=users subtree of the domain subtree, and has a mail: field (inetOrgPerson) listing their email address/login name. I am trying to use auth_bind: when I login with jackmc(a)lorentz.com, dovecot should search for mail=jackmc(a)lorentz.com in the onelevel below ou=users,dc=lorentz,dc=com and find me as "cn=Jack McKinney,ou=users,dc=lorentz,dc=com". I have created an entry in LDAP (varmail) that should be able to do this query. Indeed, from the command line, it works: ldapsearch -h ldap.lrtz -b 'ou=users, dc=lorentz, dc=com' -D 'cn=varmail,ou=users,dc=lorentz,dc=com' -x -W -s onelevel '(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))' Enter LDAP Password: # extended LDIF # # LDAPv3 # base <ou=users, dc=lorentz, dc=com> with scope oneLevel # filter: (&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) # requesting: ALL # # Jack McKinney, users, lorentz.com dn: cn=Jack McKinney,ou=users,dc=lorentz,dc=com objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson cn: Jack McKinney givenName: Jack McKinney sn: McKinney mail: jackmc(a)lorentz.com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 ' However, it appears that dovecot performs the above query successfully, but then never uses the password and retrieved DN to attempt to bind and authenticate the user. Instead, it just times out. My dovecot-ldap.conf is: hosts = ldap.lrtz dn = cn=varmail,ou=users,dc=lorentz,dc=com dnpass = ********* ldap_version = 3 auth_bind = yes pass_filter = (&(objectClass=inetOrgPerson)(mail=%Lu)) base = ou=users, dc=%Dd scope = onelevel The dovecot log shows: Apr 3 08:13:21 fourier dovecot: auth(default): new auth connection: pid=15774 Apr 3 08:13:30 fourier dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=x.x.x.x^Irip=y.y.y.y^Iresp=<hidden> Apr 3 08:13:30 fourier dovecot: auth(default): ldap(jackmc(a)lorentz.com,y.y.y.y): bind search: base=ou=users, dc=lorentz,dc=com filter=(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) Apr 3 08:16:30 fourier dovecot: imap-login: Disconnected: Inactivity: method=PLAIN, rip=y.y.y.y, lip=x.x.x.x, TLS The OpenLDAP log shows that the query is received and that it returns a match: Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH base="ou=users,dc=lorentz,dc=com" scope=1 deref=0 filter="(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))" Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH attr=uid Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SEARCH RESULT tag=101 err=0 nentries=1 text= When I do the query from the command line, there is an additional pair of lines: Apr 3 08:18:10 fourier slapd[16106]: conn=22 op=2 UNBIND Apr 3 08:18:10 fourier slapd[16106]: conn=22 fd=28 closed I thus conclude that Dovecot is not closing the connection. -- Jack McKinney GPG 1024D/99C6A174 jackmc(a)lorentz.com YM:lfaatsnat2006 AIM:jackmclorentz "There is no parameter that makes it impossible for you to perform still more excellently." -Mario Cuomo, on the lack of a clock in baseball

[Dovecot] "Dumb" proxying?
by Dan Bongert 04 Apr '08

04 Apr '08

I'm a database noob, and it really seems like it would be overkill for my setup: I just want to proxy all connections from my DMZ to my internal mail server -- same internal server for all users. I used to use perdition for this set up, but am having issues getting it to play nicely with my new servers. Can I bypass all of the SQL stuff and just have dovecot forward all POP/IMAP connections to a specific server? Or perhaps set up a wild card lookup in the database (preferably something serverless like sqlite) so that no matter the query, it'll return one server? I don't really want to add "database management" to my list of jobs I have to do, especially for ~1000 users, and when I don't handle user creation/deletion. -- Dan Bongert dbongert(a)ssc.wisc.edu

[Dovecot] outlook2007 shows frequent imap disconnect no matter what outlook-idle setting in dovecot.conf
by Kielbasiewicz, Peter 04 Apr '08

04 Apr '08

Hello, I saw the problem quite often in various posts but could not find a real solution . Problem is that I frequently get annoying popups from outlook 2007 about imap idle timeouts which block working with outlook until the popup is acknowledged. The popup says: Your IMAP server closed the connection. This can occur if you leave the connection idle for too long. Protocol: IMAP Server: testhost Port: 143 Error Code: 0x800CCCDD I tried to run dovecot with or without "imap_client_workarounds = outlook-idle" but do not see any difference. I am running dovecot on Red Hat Enterprise Linux Client release 5.1 (Tikanga). Below is the output of some commands to get a clue about my config. Background info: Our primary mailboxes are on exchange servers. As there is a size limit on the server mailboxes I am evaluating a local storage solution for our users. Thus I set up an additional mailbox in outlook using IMAP. Local .pst files can not be backuped easily (especially when outlook is running) and I am investigating a local IMAP server where users can move their mails to. This server can easily be backuped (even incrementally when using Maildir) and users do always have access to their mails. The drawbacks are that users must have an extra login to the imap server because I have no ldap access to the company AD server from our local site domain. The solution will not be accepted though if I can not prevent the frequent disconnect popups.

[Dovecot] Confusion of Sieve filter scripts and the file separator. (Amatuer Siever)
by Jack 04 Apr '08

04 Apr '08

Hello, I have just been playing around with sieve filters to split up all my incoming mail into the correct directories. I have created some subdirectories to put mailing list emails in and just want to check if my thinking is correct. I am using namespaces with the '/' character as the separator. When creating the fileinto line on my sieve scripts I thought I would have to use the '/' character to separate the folders (as horde mail also does), but that doesn't work (and produces a "Invalid folder" error) instead I must use the '.' character. I am using the dovecot deliver module and managesieve for my sieve stuff (dovecot 1.0.13). I am just wondering if this is the correct behaviour or if it is a bug of sorts. Cheers. From, Jack

[Dovecot] Dovecot config
by Dien Phan 04 Apr '08

04 Apr '08

Hi, I've installed dovecot 1.0.13 on FreeBSD 6.3 RELEASE and now trying to configure it. Below is my config file: $ dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: maildir:~/Maildir dotlock_use_excl: yes maildir_copy_with_hardlinks: yes mail_plugins: antispam imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: verbose: yes passdb: driver: checkpassword args: /var/MailRoot/bin/dovecot_xmail userdb: driver: static args: uid=vxmail gid=vxmail home=/var/MailRoot/domains/%d/%n allow_all_users=yes socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vxmail plugin: antispam_signature: X-DSPAM-Signature antispam_trash: Trash antispam_spam: SPAM antispam_dspam_binary: /usr/local/bin/dspam antispam_dspam_args: --user;%u We are using a web mail software that allows users to login either as us 'abc' or 'abc@domain'. The problem is: when a user logs in as 'abc' (without domain part) dovecots creates a directory /var/MailRoot/domains/abc and check mail there (as I understand because %d is blank). My question is how to config dovecot so it automatically add default domain %d is blank. Thank you for help. Dien Phan

[Dovecot] Icedove (Thunderbird) crashes when reading IMAP messages
by Cam Ellison 04 Apr '08

04 Apr '08

This is a Debian lenny/sid installation. Dovecot has been installed on it for over a year, with no problems. Lately (i.e. the past few months), if I attempt to read a message, Icedove crashes. It does not do this when I read a message downloaded from the ISP's POP3 server (not that I do this very often - almost all my mail goes through Dovecot). I am now having to read email with KMail, but cannot send from it - that's another story. Googling for the past month or so reveals nothing: there seems to be no bug filed for this, and indeed I think it is an odd communication problem with dovecot that has not been seen before. Has anyone any experience with this, or any ideas how I should go about resolving it? I have not done so (because I don't know how to use the data, not being a coder), but can run strace and/or valgrind on icedove if that will help.

[Dovecot] shared Sent and Junk folders
by Tolga 03 Apr '08

Hi, For some odd reason, two of my users share the same Sent and Junk folders, therefore I keep getting errors about Sent folder reading permissions and one user reading the other user's Junk folder. What can I do about this odd problem? Regards, Tolga -- Stay with *nix :)

[Dovecot] Lmtp between hosts? (postfix/dovecot/ldap)
by k bah 02 Apr '08

02 Apr '08

I have 2 hosts: (a) - dovecot-1.0.5-6 - postfix-2.4.5-20 -> It's not the mx record for the domain, just holds the mailboxes -> Postfix uses LDAP for user lookup, dovecot too. -> Works ok if I set it to be the final mail destination, with Cyrus and Dovecot LDA (mailbox_transport). -> Has no domain associated (dns) with this ip address (b) - postfix-2.3.2-28 -> Has the mx record for that domain, has ip address that the domain points to. (users @ domain.org) -> Works ok if I install dovecot and set the mailbox_transport to be on this machine, both with dovecot and cyrus. What I'm trying to do: Have host (b) to receive mails for that domain, and by setting it's transport_maps to be /etc/postfix/transport, and there (tranport maps) point to host (a), using ltmp: "domain.org lmtp:ip_address_machine_A:24" ("domain.org lmtp:inet:ip_address_machine_A:24" does not work, gives me "fatal: valid hostname or network address required in server description: inet:ip_address_machine_A:24") Both machines have /etc/services with lmtp to port 24 tcp/udp. http://www.postfix.org/transport.5.html was not so clear to me. Ok, when I took out the "inet" part on the transport maps file, it connected to the host (a), which has this on master.cf: "machine_A_ip_address:24 inet n - n - - lmtp" it "worked", since machine (b) (received the mail and has mx record) delivered the mail to machine (a) (holds mailboxes, runs dovecot), but that stopped, machine (b) connects to port 24 on machine (a), and stays there, connected, without saying nothing (sniffed it). When I kill the connection (kill postfix on machine (a)), machine (b) complains on the log file: postfix/lmtp[704]: msg_id: to=<xx(a)xx.yy>, relay=machine_A[machine_A]:24, delay=223, delays=0.08/0.01/223/0, dsn=4.4.2, status=deferred (lost connection with machine_A[machine_A] while receiving the initial server greeting). -- questions -- I don't know if I'm doing things wrong (configuration error) or the wrong thing (should try other ways), so my questions: 1) Is this setup going to work ever, or it's wrong to try to get it to work? I want to hold mailboxes on a different host, and now I got to use dovecot (in case I hear: "try it with cyrus instead" =o)). 2) Viewing from the machine that receives the mail, and has mx record, the transport should be lmtp, right? Since it's now a matter of "delivery". Postfix: <...> -> <qmgr> -> (<local> or <smtp> or <pipe>) When using lmtp, I'm in <local>?? I mean, to get the message to the other machine (just mailboxes, no mx) I SHOULD USE LMTP(?) 3) Viewing from the machine holding the mailboxes, is there a way to make dovecot listen on that port? Or should I continue to use Postfix, and use postfix on this machine to deliver to dovecot (dovecot lda config works ok if using 1 and only 1 machine for everything - mx record, mailboxes). With Cyrus I talked lmtp directly, Postfix receives the mail and uses lmtp to talk to cyrus, using a unix socket. If anyone replies to the topic, and the discussion goes deeper on some of the alternatives, I paste my configs and come with further details, since what's working isolated I didn't paste here. Previous tests with just Cyrus or Dovecot on 1 machine setup worked, so I think it would just "bloat" the mail with information. thanks = -- Powered by Outblaze

Hello. Is it exist a plugin to alert when a POP/IMAP account has a warning quota (like 90%)? Or, do you know a solution to do it? The alert could be an email sent. Thanks. - Nicolas.

[Dovecot] Outlook cant connect to POP server.
by "Fábio M. Catunda" 02 Apr '08

02 Apr '08

Hi, I'm having a weir situation with MS Outlook and dovecot. I'm using POP for some users, some can connect, others cant. With tcpdump I got this packet coming from client to server: 2008-03-31 18:30:20.913718 IP (tos 0x0, ttl 128, id 1082, offset 0, flags [DF], proto: TCP (6), length: 48) 192.168.12.9.1072 > 192.168.5.124.110: S, cksum 0x90db (correct), 2564735473:2564735473(0) win 65535 <mss 1460,nop,nop,sackOK> E..0.:@...c.... ...|.0.n........p............... But the server never give an answer. I don't have any idea why the server do not answer, in error.log and info.log I got nothing. Dovecot version: 1.0.rc15-2etch3 (Debian package) And those are the workarrounds that I enabled: pop3_client_workarounds = outlook-no-nuls oe-ns-eoh I'm kind of lost, any tip is appreciated! Thanks!

[Dovecot] v1.1.rc4 released
by Timo Sirainen 01 Apr '08

01 Apr '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc4.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc4.tar.gz.sig I didn't have time/energy to fix everything I wanted, so it'll probably be a few more RCs left until v1.1.0. This is anyway an important release, because it fixes two buffer overflows in search code which have been in all v1.1 releases (but not v1.0). Really stupid mistakes, I must have been tired or something when writing the code.. Anyway I now added code to notice these kind of buffer overflows when they happen (if --enable-debug is used), so hopefully these will be the last ones. * Fixed two buffer overflows in str_find_init(). It was used by SEARCH code when searching for headers or message body. Added code to catch these kind of overflows when compiling with --enable-debug. Found by Diego Liziero. + LDAP: Added debug_level and ldaprc_path settings (OpenLDAP-only) + Squat: Added fts_squat = partial=n full=m settings. See the wiki. - dbox metadata updating fixes. - quota: backend=n didn't work - SEARCH RECENT may have returned non-recent messages if index files were created by v1.0. - If mailbox was opened as read-only with EXAMINE, STOREs were permanently saved. - LDAP: Templates were somewhat broken (by richs at whidbey.net)

[Dovecot] deliver tries to compile already compiled sieve script
by Alexander Prinsier 01 Apr '08

01 Apr '08

Hello, I'm trying to setup dovecot with sieve support in a way where all sieve scripts are precompiled. All sieve scripts are in /var/cache/sieve/. I believe I discovered a bug here. I describe below how to reproduce it. Dovecot and the user that deliver runs as do not have write permission in /var/cache/sieve/. h01:/var/cache/sieve# ls -la total 16 drwxr-xr-x 2 ecp ecp 4096 Mar 31 21:32 . drwxr-xr-x 10 root root 4096 Mar 31 20:14 .. -rw-r--r-- 1 ecp ecp 88 Mar 31 21:32 mailtest1(a)domain.com.sieve -rw-r--r-- 1 ecp ecp 132 Mar 31 21:32 mailtest1(a)domain.com.sievec When deliver runs it logs this error: open(/var/cache/sieve/mailtest1(a)domain.com.sievec.tmp) failed: Permission denied This indicates deliver tries to compile the script, even though the compiled version already is there. To verify I tested another case. I make the compiled script immutable and I did a chmod 777 on /var/cache/sieve/. Then deliver logs this error: rename(/var/cache/sieve/mailtest1(a)domain.com.sievec.tmp, /var/cache/sieve/mailtest1(a)domain.com.sievec) failed: Operation not permitted And deliver created the file mailtest1(a)domain.com.sievec.tmp. Some relevant pieces of my dovecot.conf: protocol lda { mail_plugins = quota cmusieve ... } plugin { sieve = /var/cache/sieve/%u.sieve } Anyone can help me? Is this an error on my end, or really a bug? Alexander

[Dovecot] Dovecot 1.1rc3 crashes with Dbox + imap_quota plugin

Version: Dovecot v1.1.rc3 OS: CentOS 5 running in OpenVZ CPU: x86_64 Was running fine with maildir and decided to get dbox a try. Test user created with a dbox mailstore backend and when a client logs in that tries to run a getquotaroot imap command the process SIGSEGV's.

[Dovecot] Bug in db-ldap.c with Dovecot1.1rc3
by richs＠whidbey.net 01 Apr '08

01 Apr '08

If using LDAP as a userdb with a "quota_rule" configured, the order of the LDAP entry can distort userdb results, depending on where the quota attribute is found. For instance, with this "dovecot-ldap.conf" snippet: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaKb=quota_rule=*:storage=%$ And this example LDAP entry: dn: uid=testuser,ou=people,dc=domain.com uid: testuser homeDirectory: /mail/testuser gidNumber: 100 cn: testuser quotaKb: 20480 uidNumber: 121212 When db_ldap_result_iterate_next_all() runs, "quotaKb" is encountered, which causes "ctx->template" to be set. On the next iteration, "uidNumber" is encountered, but "ctx->template" is still set, causing the "uid" value to be prepended with "*:storage=". This is reflected by an error in the log as: Invalid UID value '*:storage=121212' This can be fixed by adding a line after 1118 to src/auth/db-ldap.c: ctx->template = NULL; Hope this is helpful to someone, -Rich

[Dovecot] Wrong UIDs returned from mailbox_transaction_commit_get_uids()
by Ron Avriel 01 Apr '08

01 Apr '08

Hi, Wrong UIDs are returned from mailbox_transaction_commit_get_uids() in dovecot-1.1.rc3. The problem is in: int mailbox_transaction_commit(struct mailbox_transaction_context **t) { uint32_t tmp; return mailbox_transaction_commit_get_uids(t, &tmp, &tmp, &tmp); } It should be: int mailbox_transaction_commit(struct mailbox_transaction_context **t) { uint32_t tmp1, tmp2, tmp3; return mailbox_transaction_commit_get_uids(t, &tmp1, &tmp2, &tmp3); } After this fix it works OK.

[Dovecot] public folders fchown error
by junk＠mc1.mccarthy.ac 01 Apr '08

01 Apr '08

I was hoping this would be the right place to look for some help, I cannot make public folders get the right permissions. I continually get the fchown error in logs, and have googled high an low to find multiple solutions that do not work for me. I'm using maildir. I have sendmail with postfix distributing my mail. I created maildir's in each users personal directory. I then thought it would be neat to set up a public folder that people could dump spam and ham into, then have a cron script go through the directory and automatically sort it for bayes. However, when I put a file in the public folder, the permissions do not seem to work. I've put a dovecot-shared file with root.mail permissions, 660, in just about every directory (all the public folder directories, and every personal user's control and index location), I've chmod'd to 777 each file and folder to test, etc, and no matter what, the dovecot.index.tmp in the user's index folder comes through with their permissions, and this error shows up. Am I thinking this is something different then what it is or am I completely off base?

[Dovecot] Setting for deleting old messages from Trash?
by David Rosenstrauch 31 Mar '08

31 Mar '08

Hi. Just switched to Dovecot from Courier last week and have been very pleased so far. The conversion was extremely painless, and I only hit a few small configuration issues before I was able to get the server up and running. Since then, I've been quite pleased - Dovecot's been very stable, and a good bit faster than courier as well. However, there's one nice feature from courier that I used to use that it doesn't seem like Dovecot provides. Wanted to see if that was indeed the case and, if so, if there was any workaround. In Courier, there was a setting whereby the server would automatically delete messages in the Trash once they were of a certain age. (The default was 7 days.) However, looking through the dovecot.conf, it didn't appear that Dovecot had any comparable setting. Anyone know how I might achieve this with Dovecot? TIA, DR

[Dovecot] mbox with sub-folders and messages?
by Richard Lefebvre 31 Mar '08

31 Mar '08

Hi, Is it possible to have dovecot configured to use mbox format and yet have folders that contains sub-folders and messages? I'm thinking of a simple setup where any files directory with extension .sbd are presented to the IMAP client without the extension. So if you have a mbox file named BOX01 and a directory name BOX01.sdb would show has one on the client side (note: that is the way Thunderbird keeps it's mail locally). I know that the Maildir format does the sub-folders+messages, but I'm not really interested by the one file per email. Richard

[Dovecot] Using LDA with postfix and virtual users
by Chris Cohen 28 Mar '08

28 Mar '08

Hi list, I have 7 virtual users in a sql database. I don't want any systemusers or local delivery using postfix. On the postfix side everything works fine as long as I use the 'local' delivery agent. But since I want to use dovecot's sieve functionality I set local_transport to dovecot. From now on Postfix seems to ignore local_* settings like local_recipient_maps. Here is my current configuration: log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps managesieve login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:/var/mail/%u mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): /var/mail/%u/dovecot/sieve/ sieve(default): sieve(imap): sieve(managesieve): /var/mail/%u/.dovecot.sieve auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/var/mail/%u socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: /var/mail/%u/.dovecot.sieve And my postfix configuration: alias_maps = mysql:/etc/postfix/alias_maps-mysql.cf command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/lib/postfix data_directory = /var/lib/postfix inet_interfaces = all local_recipient_maps = mysql:/etc/postfix/local_recipients-mysql.cf $alias_maps local_transport = dovecot mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = unixhosts.org myhostname = amy.unixhosts.org mynetworks = 127.0.0.0/8 myorigin = $myhostname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) unknown_local_recipient_reject_code = 550 And accourding to the wiki I have: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user} As soon as I set local_transport to dovecot postfix seems to lookup local_recipients using dovecot.

[Dovecot] Mailbox to maildir conversion
by Aaron Gallagher 28 Mar '08

28 Mar '08

I just today wrote Yet Another Conversion Script. This one differs from the rest that I've seen in that it will generate a dovecot- uidlist index. I've done some testing, but not any absolutely extensive testing. It works well from what I've tried. Invocation is simple. You pass the script the maildir and the mailbox file and it parses the mailbox file. The index file is generated if there is at least one e-mail with an X-IMAP header which contains the last ID used and the IMAP UIDVALIDITY. My old mail setup was ipop3d + sendmail (now dovecot + postfix) and it had a DON'T DELETE THIS MESSAGE e-mail with the aforementioned X-IMAP header. This e-mail will not be saved in the maildir. All e-mails with an X-UID header will get an entry in the uidlist file. The script works with python 2.3 or later. I haven't tested it on pre-2.3 python versions as I don't have any installed. http://habnabit.org/mb2md.py.gz I can answer questions about it if needed. I'm also willing to try to add any suggested features.

[Dovecot] Dovecot Startup error on FreeBSD
by Dien Phan 28 Mar '08

28 Mar '08

Hi, I have installed latest Dovecot 1.0.13 on a FreeBSD 6.2 with XMail (www.xmailserver.org) It works OK except one thing: error on startup. After each reboot there are lots of such error: dovecot: Mar 28 08:54:38 Error: child 916 (login) returned error 89 dovecot: Mar 28 08:54:54 Error: imap-login: No authentication sockets found When I restart dovecot by running startup script /usr/local/etc/rc.d/dovecot.sh restart the problem disappears. I have to manually restart dovecot after each reboot. Below is used conf file $ dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: maildir:~/Maildir dotlock_use_excl: yes maildir_copy_with_hardlinks: yes mail_plugins: antispam imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: verbose: yes passdb: driver: checkpassword args: /var/MailRoot/bin/dovecot_xmail userdb: driver: static args: uid=vxmail gid=vxmail home=/var/MailRoot/domains/%d/%n allow_all_users=yes socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vxmail plugin: antispam_signature: X-DSPAM-Signature antispam_trash: Trash antispam_spam: SPAM antispam_dspam_binary: /usr/local/bin/dspam antispam_dspam_args: --user;%u I googled and found similar post at http://www.mail-archive.com/dovecot@dovecot.org/msg01793.html, http://www.mail-archive.com/dovecot@dovecot.org/msg01798.html and http://www.mail-archive.com/dovecot@dovecot.org/msg01831.html but answers there don't meet my case. I don't use sql backend. And startup script doesn't delete /var/run/dovecot/ directory after Dovecot is started. After booting when error still there I have in this directory: $ ls /var/run/dovecot auth-master dict-server login master.pid If restart dovecot (working OK): $ ls /var/run/dovecot auth-master auth-worker.960 dict-server login master.pid As we see dovecot works when there appears a file named auth-worker.960 (the number 960 changes each time it restarted). Please help me to fix this. Thanks in advance. Dien Phan

[Dovecot] Moving main inbox file from /var/mail to ~/mail
by Romain 26 Mar '08

26 Mar '08

Hi list, I am using Dovecot version 1.0.10 in a Debian package. At the moment, i have the main INBOX of each user in /var/mail/%u and others mboxes in ~/mail/. Here is the line coming from my /etc/dovecot/dovecont.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u I would like to move the main inbox in each home folder with the rest of the others mboxes. What should be the process ? Should i only tkahe the network down, update my conf file and move the inbox of every user ? Or do I have to do something different ? Thanks Regards Romain romain(at)abakila(dot)net

Pegasus Mail 4.41 is an excellent client on Windows. It works fine with both Dovecot IMAP and POP3 (APOP, IMAP LOGIN commands only - no SASL). Responds to async events. Supports IMAP STARTTLS. Does not use IDLE - periodic CHECKs. Fast and sensible header caches, light on resources. Offline mode, but read-only, using cache (prefetch options available if body caching enabled, it's not by default to save disk space). Searching is still a bit slow, although it does its best to use IMAP substring searches when it's possible even though the folder metadata is apparently managed locally. Excellent configurability; includes semantics for the different types of separator, prefixes, and a choice of whether or not to support folders w/ messages or w/o in folders. Moves mails for trash; only purges from the Trash folder (expunge after every delete operation and don't provide end-user experience different than local folder management). Provides several tricks for faster IMAP access, one of which is to assume only the client is using the mailbox (they can all be turned off). Closed source. But a very nice client, all round. http://www.pmail.com/ http://community.pmail.com/ Cheers, Sabahattin -- Sabahattin Gucukoglu <mail<at>sabahattin<dash>gucukoglu<dot>com> Address harvesters, snag this: feedme(a)yamta.org Phone: +44 20 88008915 Mobile: +44 7986 053399 http://sabahattin-gucukoglu.com/

[Dovecot] Dovecot and kmail IMAP resources
by Anne Wilson 25 Mar '08

25 Mar '08

For some time now I have been trying to get IMAP resources working on KMail. I have followed the docs from kde, but they tell how to configure cyrus IMAP, so I've had to learn as I went along. After a lot of help from the postfix list I now have a working sasl. The ability of the user 'groupware' to log in with PLAIN has been checked in a telnet session. Everything in KMail has been set up as in the documentation, but it doesn't work. Now I'm wondering if anything in my dovecot configuration needs changing. dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/mail/mail info_log_path: /var/log/mail/mail.info protocols: imap listen: *:143 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: maildir:~/Maildir/ maildir_copy_with_hardlinks: yes auth default: mechanisms: plain login debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: I'd be thankful for any help. Thanks Anne

Now all works perfectly :-) Probably at http://wiki.dovecot.org/Plugins/xexec it is good to have link on patch/new version of module, created by you. Or attach to page file. I can do it, if it's ok. What you think?

[Dovecot] Is there a way to avoid deletion in a folder?
by "Fábio M. Catunda" 24 Mar '08

24 Mar '08

Hi, I would like to know if it's possible to avoid message deletion in a specific folder. I'm using lazy-expunge like a Trash folder and I don't want the user to enter there and try to erase the message again. Any help is appreciated. Thanks.

[Dovecot] Quotas from Active Directory LDAP
by Mohammad "Shami" Al-Shami 23 Mar '08

23 Mar '08

Hi Guys, I've been trying to get this to work for 3 days now, but no luck. I have Dovecot set with an Active Directory back-end. Everything is working properly but I can't get user specific quotas.I tried with both 1.0.13 and 1.0-rc7. All users have the same quota which is set in dovecot.conf dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login valid_chroot_dirs: /var/vmail verbose_proctitle: yes mail_extra_groups: mail mail_access_groups: mail default_mail_env: maildir:/var/vmail/%n mail_location: maildir:/var/vmail/%n mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: username_format: %Lu debug: yes debug_passwords: yes passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: maildir:storage=10240 dovecot-ldap.conf uris = ldap://172.16.201.138:3268 dn = CN=LDAP User,OU=Special Users,DC=shami,DC=net dnpass = qwerty auth_bind = yes ldap_version = 3 base = dc=shami,dc=net user_attrs = sAMAccountName=home,title=quota user_filter = (&(ObjectClass=person)(sAMAccountName=%u)) pass_filter = (&(ObjectClass=person)(sAMAccountName=%u)) user_global_uid = 1001 user_global_gid = 1001 I'm storing the quota in the title field (tried other fields as well) in the following format: maildir:storage=512000 Yet I still get 10MB for all users.

The attached patch provides a compile fix to make it compile without warnings for dovecot-1.1. I only tested whether the module is successfully loaded by Dovecot and not whether XEXEC still does what it is supposed to. It does not segfault on the xexec command, but that is all I tested. I got a backend command error and now it is bed time for me, but there is a good chance that this works if you bother to read the wiki page properly ;) So, consider this to be more like an 'It compiles! Ship it!' kind of fix. But, anyways, it should help you to get where you want. Just apply inside the xexec directory using the usual patch -p1. Let me know what you find out. Regards, Stephan.

[Dovecot] Using IMAP keywords instead of mailboxes for spam with dovecot-antispam
by Jan Oravec 20 Mar '08

20 Mar '08

Hi, Some email clients, like Evolution, use IMAP keywords to flag spam instead of moving mail to dedicated spam mailbox. This is very useful, as false positives can be easily "moved" to original mailbox simply by removing $Junk keyword. I couldn't find a way how to integrate antispam software, like dspam, with dovecot, so that antispam automatically learns ham/spam. I have found Johannes's dovecot-antispam plugin. Unfortunatelly, it doesn't have IMAP keywords support, autolearn is based on folders. Is there any solution for this use case? Thanks, Jan

Hello Dovecot users, Last week I announced my automatic Debian repository for dovecot-1.1. Asheesh Laroia requested source package support and as promised I built it this weekend. Now that it has succesfully released new packages for Timo's latest changes I have activated the new script. To use the source packages you must add the following line to your /etc/apt/sources.list deb-src http://xi.rename-it.nl/debian/ testing-auto main Package versions now look as follows: 1:<upstream-version>-0~auto+<build number> Current latest version: 1:1.1.rc3-0~auto+3 For questions, comments and requests, you can send me an e-mail.

[Dovecot] Dovecot 1.0.13 ignores auth_krb5_keytab settings
by christop 20 Mar '08

20 Mar '08

Greetings, i am using here FreeBSD 7.0-RELEASE amd64 with dovecot 1.0.13. Gssapi auth on our dovecot setup did not work for some time, so i wanted to fix it today. I run into an auth failure, where my mutt was not able to login. Also mutt was not able to login, i had a imap/mail2.physik-pool.tu-berlin.de principal in my credentials cache after an try. I can work around with a "ln -s /etc/mail.krb5.keytab /etc/krb5.keytab" to this.

[Dovecot] IMAP - multi-simultaneous-user mail store
by Tim Alberts 19 Mar '08

19 Mar '08

I'm finishing converting from POP to IMAP and I'm seeing some potentially powerful uses, but I wonder if my ideas aren't more abuses. I want to create 'multi-user' accounts that allow groups of users to archive and share emails with each other. For example, in the case of a sales department, emails from customers may have requests for new product features. I could create an IMAP storage for sales that allows the sales staff to copy these requests into a common email account. These could then be sorted and searched by the product development team to better determine what customers want where product development should go. Another example, a service/support group has some problem customers that frequently call multiple technicians for support. The service group can save all correspondence with this customer in a single location so they can better work together to provide support for this customer. The possibilities for sharing emails in groups seem endless to me, but it depends on if it's a 'use' or 'abuse' of the IMAP protocol, and if Dovecot in-particular is designed to be able to handle this. Thoughts?

[Dovecot] Converting from UW-IMAP to dovecot - odd client problems
by Michael Durket 19 Mar '08

19 Mar '08

Our installation currently uses an old version of UW-IMAP. Instead of upgrading to the latest version, we're in the process of testing dovecot 1.0.13 on a Solaris 9 machine (using a different set of network ports of course so both the old and new systems can coexist during testing). We've been asking selected users to switch from UW-IMAP to dovecot in order to test various clients and OSes with dovecot. On our system the inboxes are always on local disk, but the indexes and any folders may be on NFS or local disk (it has to do with how and where we added disk as our user population increased over time). Only a single server is ever used and I've made sure for our version of dovecot that the settings specified for NFS are as described in the Wiki article. We've noticed some oddities which we can't figure out: 1) When siwtching a Thunderbird user running on a Fedora system (latest version of Thunderbird) Thunderbird couldn't see his mail folders even when the appropriate checkbox (Server Settings -> Advanced -> Show Only Subscribed Folders) was unchecked. Clearing out the IMAP Server Directory setting seemed to fix this, but the very next day, the folders were gone again and we've been unable since to get Thunderbird to see them. Using the same version of Thunderbird, running on Mac OS X 10.5.2 yields no such problem. Another problem with this same user involved a test wherein we created a new mail folder and then deleted it. The deletion caused an error message to be displayed (inferior folders, etc) but on the Mac OS X version no such error occurred and the folder was deleted. Investigating the protocol traces for Thunderbird showed that in the error case, it attempted to rename the deleted folder as a subfolder of the Trash folder (thus generating the error message) but on the Mac OS X version, it actually deleted the folder (which would seem to make more sense). The settings pertaining to the Trash folder are the same on both clients. 2) When switching an Apple Mail.app user running on Mac OS X 10.4.11 (Tiger) at the latest patch level, things appeared to work fine, and then the user mentioned that no mail was showing up in her inbox. Closing and restarting Mail.app appeared to fix that temporarily. She normally keeps a large number of messages in her inbox (approximately 7000+) and receives a large number of messages each day (several hundred). In this case, the Postfix mail logs showed that mail was being received, and the procmail delivery log for this user showed that procmail was putting the mail in her inbox, yet Mail.app was not indicating the presence of new mail (until it was restarted). Also Mail.app became very very slow at startup and shutdown (taking several minutes as compared to a few seconds normally). We've had no problems so far with another Tiger Mail.app user (but his inbox is considerably smaller) and no problems yet with converting a Eudora user running under Windows, but this is a stumbling block in our efforts to convert to dovecot since we'd hoped to be able to switch users over fairly easily (just by changing the port address mostly). While these woud seem to be client problems at first glance, the common factor of course is dovecot. There are no problems with any of these clients using UW-IMAP. I'm hoping that perhaps there are some readers of this list that might have seen similar problems and know of solutions, or could point me to some ways of debugging these problems (with Thunderbird I can at least debug IMAP protocol exchanges, but since dovecot doesn't log IMAP exchanges for specific IPs and since the socket connections are all via STARTTLS I can't use tcpdump so I'm kind of at a loss for how to track these things down short of patching the dovecot code to put in tracing messages). Any suggestions would be appreciated (and would help us complete our conversion to dovecot). Michael Durket

[Dovecot] Dovecot / FreeBSD / Nfs mailstore / Index=memory
by Xavier Beaudouin 19 Mar '08

19 Mar '08

Hello, I have recently changed imap from Courier-imap to dovecot because of serial problems with courier-imap, I have being forced to do it very quickly... and without extensives tests. I have 3 mails servers (freebsd based) behind a load balancer and a nfs mailstore on a netapp. On my first tests I have setup the index into some nfs shared mount, but it seems that some imap clients are going mad when deleting files (mostly because they do open some new imap connection and the index was not clean) so I have changed index to memory. This has fixed one of my problems. Now I have some strange problems is that NFS activity passed from about... 5mbps to more than 70Mpbs... Is there any reasons about that ? OS: FreeBSD 6.2-p11 / x86 Dovecot : 1.0.13 (freebsd ports) Auth: ldap based Nfs mail spool : filer:/vol/vol0/mail /var/mailusers nfs rw,nfsv3,mntudp,bg,noatime,nolockd 0 0 Thanks, /Xavier
