[Dovecot] possible quota bug ?
by fernando.figaro＠uol.com.br 31 Mar '14

31 Mar '14

Hi, I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins. When I list maildirsize file, I get: 1073741824S 17952 16 If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries: 1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1 I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem? Thanks, Fernando

[Dovecot] dsync in a cronjob to replace offlineimap
by Guilhem Moulin 24 Mar '14

24 Mar '14

Hi list, Replacing offlineimap with dsync for IMAP-to-IMAP synchronization (using dovecot 2.1.7) is working great, but now that I upgraded to 2.2.9 I'd like to take advantage of the incremental replication [1]. I don't think having a separate replicator process & notifications suits my configuration, as I want to sync my server with my laptop which is not always on or might be behind a firewall. After reading ‘replication/replicator/dsync-client.c’ I was thinking of writing a small wrapper around dsync performing a daily full replication and updating the state otherwise. The following works great in a cronjob doveadm sync -l30 imap.example.org but when I try to get the current state doveadm sync -l30 -fs '' imap.example.org >~/mail/dsync.state and later use incremental replication state=$(< ~/mail/dsync.state) doveadm sync -l30 -s "$state" imap.example.org >~/mail/dsync.state the state seems to somehow quickly become "stale" and messages stop being retrieved from the server. I understand that dsync's incremental replication is mostly intended to be used by the replicator process, but I'm wondering whether it's also possible to use it manually ;-) If so, how to keep a sane state? Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/Replication

[Dovecot] When does the replication run normally?
by Daniel Thielemann 18 Mar '14

18 Mar '14

Hi, I got my manual dsync finally working and can replicate mails by initiate it from comandline (doveadm sync -u mail(a)domain.dom -d), but it does not run by itself (per dovecot replication). When does dovecot invoke the replication normally? Thanks in advance Daniel

[Dovecot] Disable/patch iOS7 Full Body Search
by Chris Laif 12 Mar '14

12 Mar '14

As mentioned in other posts [1], iOS7 Mail App uses a multi-folder full body search by default. As to my knowledge, this behavior cannot be disabled within the Mail App. Is there any way to disable/patch this behavior on the server side? My users complain that searching now takes 'forever'. They were happy with the old behavior (searching From/To/Subject only). I do NOT want to setup/maintain a dovecot FTS. I just want to have the 'old' behavior. Chris [1 ]http://blog.fastmail.fm/2013/09/17/ios-7-mail-app-uses-multi-folder-body-searches-by-default/ ("Our plan at FastMail is to detect iOS clients, and convert all searches into FUZZY searches.")

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Dimos Alevizos 08 Mar '14

08 Mar '14

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all servers are Centos. The problem is that at times we see mailboxes (all of them are in mbox format) beginning with FFrom or FrFrom and of course dovecot says it's not a valid mbox file. If we manually remove the offending extra characters from the beginning of the file everything is working again, but often the same user will show the problem again tomorrow.

After activating the mail_log plugin hoping it'll help us locate the problem we run across this case : The user (let's call him user(a)domain.gr) logs in via pop3 and deletes some mails but one of them fails: Jun 19 11:09:18 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.40, mpid=1389, secured, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:18 director5 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20670, msgid=<9f5b1a20a9428ed31a9e7e42ce4411f08d0.20130612070424(a)mail84.us2.rsgsv.net>, size=36526 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20671, msgid=<b27d72dc5a47a3235a232494c6fe8aa0(a)newsletter.stockout.gr>, size=4637 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20672, msgid=<1113670779560.1111910791405.1470.2.32032003(a)scheduler.constantcontact.com>, size=38655 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20673, msgid=<83600a274c1407c5aa4c263e2592cb54(a)debop.gr>, size=1181688 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20674, msgid=<F2A59BE7-007A-4567-9BA5-803446C3D7F8(a)bernier-eliades.gr>, size=61116 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Next message unexpectedly corrupted in mbox file /var/mail/K/Y/V/domain_gr_user_007 at 1 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Cached message offset 1 is invalid for mbox file /var/mail/K/Y/V/domain_gr_user_007 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=2/1502843, del=122/359, size=137448432 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Warning: Our dotlock file /var/mail/K/Y/V/domain_gr_user_007.lock was deleted (locked 9 secs ago, touched 9 secs ago) Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Error: file_dotlock_delete() failed with mbox file /var/mail/K/Y/V/domain_gr_user_007: No such file or directory Jun 19 11:09:27 director5 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 83.235.173.26 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> However he's still able to log in again : Jun 19 11:11:36 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.40, mpid=10094, secured, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:36 director3 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:51 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=0/0, del=0/237, size=75036938 Jun 19 11:11:51 director3 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 85.74.231.10 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> A few minutes later he receives another mail which is delivered with no problem : Jun 19 11:30:39 corvus amavis[546]: (00546-22) Passed CLEAN, [91.190.168.40] [91.190.168.40] <tk-14439(a)free.splio.com> -> <user(a)domain.gr>, Message-ID: <58175-bWFyaW5hQGJlcm5pZXItZWxpYWR lcy5ncg==(a)free.splio.com>, mail_id: J1P-0WpmQksJ, Hits: 1.412, size: 9025, queued_as: 02BA4AE00414, Tests: [DKIM_VALID=-0.1,DKIM_VERIFIED=-0.1,FREEMAIL_FROM=0.001,HTML_IMAGE_RATIO_04=0.61,INVALID_MSGID=1,URIBL_BLOCKED=0.001], autolearn=disabled, 1533 ms Jun 19 11:30:39 corvus smtp/smtpd[1283]: proxy-accept: END-OF-MESSAGE: 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 02BA4AE00414;

[Dovecot] Dovecot Migration: Retrieving/Logging POP/IMAP Passwords in Plaintext
by Traiano Welcome 05 Mar '14

05 Mar '14

Hi List I'm currently in the process of migrating my dovecot imap/pop users to a new server and have to extract their passwords in order to import them into the new system (different password encryption schemes). I've tried enabling auth_* debug parameters in my dovecot.conf in the hope that this would result in logging plaintext passwords to the dovecot log. However dovecot does not log the passwords in plaintext under any debugging configuration. My question: Is there any other configuration of dovecot that would allow me to capture POP/IMAP passwords at a successful login time? Dovecot version: 1.0.7 (from dovecot-1.0.7-7.el5_7.1 rpm) The output of dovecot -n is: --- # 1.0.7: /etc/dovecot.conf info_log_path: /var/log/dovecot.debug verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~:INBOX=~/Mailbox mail_debug: yes 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/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 --- My dovecot.conf is as follows: ------ info_log_path = /var/log/dovecot.debug verbose_ssl = yes mail_location = mbox:~:INBOX=~/Mailbox mail_debug = yes protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/run/dovecot/auth-client mode = 0666 } } } dict { } plugin { } --- Many thanks in advance!

[Dovecot] Error "Initializing mail storage ..." after upgrading to 2.2.10
by Götz Reinicke - IT Koordinator 04 Mar '14

04 Mar '14

Hi, I did the upgrade frpom 1.2.x to 2.2.10 and had some warnings/errors on a very few accounts/mailboxes. All of them where permission related and solved. Dovecot rocks again. But on one mailbox I do get an error: Error: user rechnnugseingang-animationsinstitut: Initialization failed: Initializing mail storage from mail_location setting failed Error: Invalid user settings. Refer to server log for more information. There is a homedirectory and the permissions are set like on all other accounts. The username is quite long (35 characters) but an other one with 34 is working fine. And before the upgrade there was no error. Thnaks for any help or hint. Regards .
