[Dovecot] mbox to Maildir conversion
by Albert E. Whale 28 Oct '08

28 Oct '08

I've been running a mbox solution using UW's IMAP server. I've run it for years. Now do to heavy message volumes, I've decided to to take the plunge to convert to the Maildir format. I am currently testing a single user, and have successfully converted the mail messages from mbox to Maildir format, and now I am setting up the procmail tool to place the messages into the correct folder. I have been following the http://wiki.dovecot.org/Migration/MailFormat formula, but now have a question. New Messages are now being placed into the ~user/Maildir/new folder. However, when I attempt to retrieve those messages, Dovecot does not find them. Why not? -- Albert E.

[Dovecot] Possible header parsing problem
by Eric Stadtherr 28 Oct '08

28 Oct '08

Hi, I ran into a problem wherein my mail client (RoundCube) would not display a message from a Dovecot IMAP server (claiming that the message had no content). The raw source of the message looked fine, but the body structure returned by Dovecot only had the first text/plain part and not the alternative text/html part. The message looks like: ... headers removed ... X-Mailer: Lotus Notes Release 6.5.1 January 21, 2004 Message-ID: <...> From: user(a)host.domain Date: Mon, 20 Oct 2008 14:15:55 -0600 Content-Type: multipart/alternative; boundary="=_alternative 006F3A73872574E8_=" This is a multipart message in MIME format. --=_alternative 006F3A73872574E8_= Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=us-ascii blah blah blah --=_alternative 006F3A73872574E8_= Content-Transfer-Encoding: 7bit Content-Type: text/html; charset=us-ascii <br><font size=2 face="sans-serif">blah blah blah in HTML</font> --=_alternative 006F3A73872574E8_=-- I did a little bit of tracing through the parsing code (message-header-parser.c:message_parse_header_next()) and it appeared that the boundary in the Content-Type header was not parsed correctly, evidently because the header line was folded in the middle of the boundary string. RFC 822 appears to allow folding in a quoted string like this (§3.3 "quoted-string"), so I'm curious whether the parsing is working correctly. Thanks for your help! Here is my Dovecot information: version: 1.1.4 "dovecot -n" output: # 1.1.4: /usr/local/etc/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 384).

[Dovecot] Gah, pop3 falling over
by Brandon Lamb 27 Oct '08

27 Oct '08

Why would I be seeing a million of these? dovecot: 2008-10-27 09:12:33 Warning: chdir(/mail/mail/domain/u/username/) blocked for 18 secs Two servers were working fine and then all of a sudden this morning bam 500 load and theres a million dovecots and tons of these lines in the logs. It is like everyone gets up at exactly 8:30 and hits the pop3 server at once. Anyway, dovecot 1.1.5, nfs mount, debian lenny/sid amd64, 2.6.26-1-amd64 i had the performance mode options for login configured, i just set back to the single process per login though, I think that hasnt fallen over that way but I really dont remember anymore. I included the dovecot -n using the suggest performance login settings?

[Dovecot] Released v1.1.5 and v1.2.alpha3
by Timo Sirainen 27 Oct '08

27 Oct '08

http://dovecot.org/releases/1.1/dovecot-1.1.5.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.5.tar.gz.sig http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha3.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha3.tar.gz.sig A combined release announcement for a change. :) Largest changes since v1.1.4: * Dovecot prints an informational message about authentication problems at startup. The message goes away after the first successful authentication. This hopefully reduces the number of "Why doesn't my authentication work?" questions. + Maildir/dbox: Try harder to assign unique UIDVALIDITY values to mailboxes to avoid potential problems when recreating or renaming mailboxes. The UIDVALIDITY is tracked using dovecot-uidvalidity* files in the mail root directory. + Many logging improvements - In some conditions Dovecot could have stopped using existing cache file and never used it again until it was deleted. - pop3 + Maildir: Make sure virtual sizes are always written to dovecot-uidlist. This way if the indexes are lost Dovecot will never do a huge amount of work to recalculate them. - mbox: Fixed listing mailboxes in namespaces with prefix beginning with '~' or '/' (i.e. UW-IMAP compatibility namespaces didn't work). - dict quota: Don't crash when recalculating quota (when quota warnings enabled). - Fixes to handling "out of disk space/quota" failures. - Blocking passdbs/userdbs (e.g. PAM, MySQL) could have failed lookups sometimes when auth_worker_max_request_count was non-zero. - Fixed compiling with OpenBSD Largest changes since v1.2.alpha2: + Added userdb checkpassword (by Sascha Wilde) + Autocreate plugin: http://wiki.dovecot.org/Plugins/Autocreate + Listescape plugin: http://wiki.dovecot.org/Plugins/Listescape - All the same fixes as for v1.1.5 I was thinking about waiting for Kolab people's work for shared mailbox support to get done, get that code to v1.2 tree and then release v1.2.beta1 with feature freeze.

[Dovecot] Problems with the pop3 part of dovecot
by Brandon Lamb 27 Oct '08

27 Oct '08

Hello, I originally just typed up a 5 paragraph essay on my problems but just deleted it all. basically I need to find out where to start looking to find out what is the problem with my dovecot pop3 setup. I switched from courier imap/pop3 to dovecot imap/pop3. I have had super high loads (40+ and overnight one server went to 511) and its been a nightmare fighting with this new setup for the last two weeks. I did manage to narrow the problem down to it being with the pop3 part of dovecot. I am not sure why the load keeps going so high. The first week I attributed it to users having to redownload mail and reindex (we were aware of the UIDL problem), but two weeks later one of my machines overnight went to 511. I have changed so many config options to try to make it work that I have become overwhelmed and feel like I have tried everything to get the right settings. I am running four 64bit machines with amd 9850 cpus, 4 gigs ram, the mailstore is nfs mounted, the nfs server is using xfs. Debian lenny/sid. I dont know what to do, I am almost debating going back to courier pop3 and going through the week of support calls of customers downloading mail again but that is a last ditch effort. I can understand if i just need to wait it out while things are indexed for dovecot and stuff, but machines falling over and loads of 40 to 500 just for dovecot seems not right. so, where do I start?

[Dovecot] Problem with quota dovecot as lda and mysql
by Claudio Prono 27 Oct '08

27 Oct '08

Hello to all, That is my situation: I am trying to use dovecot as LDA with postfix, mysql e postfixadmin. So, all the users are stored in mysql, with quota password and all other things. All works properly, except for quota. I am trying to do some tests, but is not clear to me how to debug that problem. Scenario: user with 15 Mb of quota. That is my dovecot.conf (dovecot version 1.1.3 on OpenSuSE 11.0): dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot-err.log info_log_path: /var/log/dovecot-inf.log protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 51 last_valid_uid: 51 first_valid_gid: 51 last_valid_gid: 51 mail_location: maildir:/var/mail/virtual/%d/%u mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %Mf auth default: passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir quota: maildir:user quota And this is my dovecot-mysql.conf: driver = mysql connect = host=127.0.0.1 port=3306 user=postfix password=XXXXXXXXXXX dbname=postfix default_pass_scheme = MD5-CRYPT password_query = SELECT username as user, password, '/var/mail/virtual/%d/%u' as userdb_home,'maildir:/var/mail/virtual/%d/%u' , 51 as userdb_uid, 51 as userdb_gid FROM mailbox WHERE username = '%n@%d' AND active = '1' user_query = SELECT maildir, 51 AS uid, 51 AS gid, concat('dirsize:storage=', ROUND( mailbox.quota / 1024 ) ) AS quota FROM mailbox WHERE username = '%u' AND active = '1' But.. when i send a mail that "overquota" the mailbox, nothing happens, the mail is normally delivered to maildir and the quota is not considered. An example of the process: I take a mailbox with 15Mb of quota, like test(a)test.com: Email Nome Quota (MB) Ultima modifica Attivo test(a)test.com test 15 2008-10-27 11:47:43 SI <edit-active.php?username=test%40test.com&domain=test.com> modifica <edit-mailbox.php?username=test%40test.com&domain=test.com> cancella <delete.php?table=mailbox&delete=test%40test.com&domain=test.com> I try to send an email to it: Oct 27 11:48:53 dns postfix/smtpd[3489]: connect from cla.mediaservice.pri[192.168.87.70] Oct 27 11:48:53 dns postfix/smtpd[3489]: D8DF2837: client=cla.mediaservice.pri[192.168.87.70] Oct 27 11:48:53 dns postfix/cleanup[3494]: D8DF2837: message-id=<49058EB2.5080208(a)atpss.net> Oct 27 11:48:58 dns postfix/qmgr[2636]: D8DF2837: from=<claudio.prono(a)atpss.net>, size=7716371, nrcpt=1 (queue active) Oct 27 11:48:58 dns postfix/smtpd[3489]: disconnect from cla.mediaservice.pri[192.168.87.70] Oct 27 11:48:59 dns postfix/pipe[3496]: D8DF2837: to=<test(a)test.com>, relay=dovecot, delay=5.6, delays=4.9/0/0/0.71, dsn=2.0.0, status=sent (delivered via dovecot service) Oct 27 11:48:59 dns postfix/qmgr[2636]: D8DF2837: removed Fine, the mail was put into mailbox. dns:/var/mail/virtual/test.com/test@test.com # du -h 0 ./cur 7.3M ./new 0 ./tmp 7.3M . Now i try to put in overquota the mailbox with other 2 mails of the same dimension.

I have already readed the quota howto of dovecot, with no results, all seems ok, but quota is not used... PLS HELP!!!
