[Dovecot] Embedded "From<space>" Lines
by Lennart Lövstrand 29 Oct '08

29 Oct '08

Hi. As some of you may remember, I reported a problem a while back where dovecot 1.1.beta14 (as well as dovecot 1.0) would corrupt mbox-style mailboxes by ignoring the Content-Length header and breaking up messages with embededed "From<space>" lines. I recently downloaded Dovecot 1.1.5 and noted to my pleasure that this bug now has been fixed. That's great! This fix envolves checking to see if the expected_body_size (from the Content-Length header) is larger than the body_size produced by the "From<space>" scanner, and if so, if there is a valid "From<space>" line at the "expected" end of the message. However, I also noted that there's a case which the fix doesn't cover, and that's where the "From<space>" line appears as the first line of the body of the message. When this happens, the body_offset will point to the blank line between the headers and the body and not the actual first line of the body. This will cause the stream to be mispositioned at the time of the "From<space>" verification check in istream_raw_mbox_get_body_size and the (actually correct) expected_body_size will be rejected. I have enclosed a simple diff that will work around this by adjusting the body_offset to point to the next line at the time of call to istream_raw_mbox_is_valid_from in istream_raw_mbox_get_body_size. This appears to handle the problem correctly in all the test cases I have. To anyone else who has run into this problem and gotten corrupted mailboxes as a result, I can also offer an mbox checker that will attempt to detect and repair this problem in existing mailboxes as well as inspect them for other problems. I'm not ready to send it out for a full release yet, but interested beta testers are invited to contact me directly. Cheers, --Lennart

[Dovecot] quota warning not working
by Claudio Prono 29 Oct '08

29 Oct '08

Hi all, I have finally get working the quota with dovecot. Now i am setting up the quota warning, with this in dovecot.conf: quota_warning = storage=70%% /usr/bin/quota_warning.sh 70 In the plugin section naturally. All seems to work fine, the quota is calculated right, but seems the script is not executed... In dovecot logs i have this: deliver(test(a)test.com): Oct 27 15:14:53 Info: Quota warning: bytes=10752000 (70%) messages=0 (0%) command=/usr/bin/quota_warning.sh 70 But...nothing happens. My quota_warning.sh is this: #!/bin/bash PERCENT=$1 echo "/usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf" > /var/log/quotanotify cat << EOF | /usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf From: postmaster(a)mediaservice.net Subject: quota warning Your mailbox is now $PERCENT% full. EOF I have added the echo for debug pourpose, but no file was created, so the script is not executed. I thinked is a permission problem, but seems not. Now the script is like this: -rwx--x--x 1 dovecot dovecot 317 Oct 27 15:30 /usr/bin/quota_warning.sh What can be the problem? Stuck!!!

[Dovecot] Dovecot pop3 and SonicWall?
by Brandon Lamb 29 Oct '08

29 Oct '08

Hello Has anyone else run into a problem with dovecot pop3 and sonicwall? A week after switching to dovecot we had two local customers call and report they could no longer download emails with attachments. It turned out to be the email macro filter on the router. After the first report I thought maybe the customer had just changed something or it was a fluke, but then a day later we had the second call with the same issue. For some reason, after us switching the sonicwall's email macro filter was catching any attachments as a threat. I couldnt see how changing pop3 servers could affect that, but I guess anything is possible. I just emailed sonicwall and am waiting for a response from them now as well. Hopefully maybe someone has heard of this before. Unfortunately, I dont know if this was pure coincidence, or if both customers happened to have updated their sonicwall software, or maybe it autoupdates, I have no information on it.Of course to them it looks like we broke it. We just had them both turn this rule off for now.

[Dovecot] Best configuration of dovecot for limit Outlook problems with IMAP
by Alessio Cecchi 29 Oct '08

29 Oct '08

Hi, in some installation where users using IMAP and Outlook Express I have some problems. Outolook randomly presents problems in messages retrieving, for example: "Outlook Express is unable to retrieve the requested message because the server no longer has the message available.... server response: Fecth Completed" or "Message could not be displayed" error message when I try to view an Outlook Express e-mail message I'm using dovecot 1.1.4 with qmail and vpopmail. This is my dovecot configure options: ./configure --prefix=/usr --sysconfdir=/etc/dovecot --localstatedir=/var --with-ssldir=/etc/ssl and this my dovecot config: # dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot-err.log info_log_path: /var/log/dovecot/dovecot.log ssl_cert_file: /etc/apache2/ssl/comun.crt ssl_key_file: /etc/apache2/ssl/comun.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_greeting: Ready login_process_per_connection: no first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_uid: 89 mail_gid: 89 mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle delay-newmail namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: verbose: yes debug: yes passdb: driver: checkpassword args: /home/vpopmail/bin/vchkpw userdb: driver: prefetch args: uid=89 gid=89 home=/home/vpopmail/domains/%d/%u plugin: quota: maildir What further changes to the configuration of dovecot could I do?

[Dovecot] Dovecot and quota enforcement - only reporting?
by dovecot＠corwyn.net 29 Oct '08

29 Oct '08

I'm currently setting up postfix and dovecot with virtual users (mysql), imap, and quotas. I'm setting the quotas using mysql. I have quotas working correctly, and I can telnet into the imap server, and submit . getquotaroot inbox and get back valid quota information. I get a maildirsize file in the Maildir directory. Very cool. When I delete mail and expunge it, the quota updates. However, inbound email doesn't appear to update the quota. Two questions, probably related: What causes the quota (which I presume is the maildirsize file) to update? Is there any actual quota enforcement, or just reporting? Because if I send mail to an account, even if it currently reporting (via maildirsize or . getquotaroot) that the user is over quota, they still can send and receive email. Thanks!

[Dovecot] Authentication Error Message formats
by Albert E. Whale 29 Oct '08

29 Oct '08

I have been using UW's IMAP server and I am converting to Dovecot for Maildir support. When a user fails authentication, or a user does not exist, it appears that the same message is used for these events. Is there a way to indicate that the user does not exist (Invalid user), and authentication Failure (Failed Password)? Clearly these two failures indicate a different error in the system. One that some forgot their password, the other indicates a dictionary attack. -- Albert E.

[Dovecot] Empty/corrupt mail leads to duplicate delivery
by Marc Herbrechter 29 Oct '08

29 Oct '08

Hi, when the attached mail was stored in a maildir, fetching mail via POP3 lead to multiple delivery of mails in that maildir to the client (Outlook). I replaced the domain with dots. This is the dovecot configuration: --snip-- protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain passdb pam { args = "*" } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } --snip-- Version: dovecot-1.1.4-r1 (Gentoo) Gentoo applies the attached "expire" patch. I tried to reproduce the behavior, but when I send an empty mail via telnet, nothing happens. The box is running Amavis, don't know if that helps. -- Mit freundlichen Grüßen, with kind regards, Marc Herbrechter <mh(a)zebroc.de>

[Dovecot] Keep the email on the server
by Rubens A. Mascari 29 Oct '08

29 Oct '08

Hello, I migrate my server POP3/IMAP recently the Courier-IMAP for Dovecot and am having problems when the user configures your e-mail client to leave a copy of mail on the server. All mail in the inbox, are brought all the time that you check your mailbox input via POP3, causing a large traffic of unnecessary data every time. In my opinion you should bring only the new mail, unread. Can you tell me if this is a configuration issue on Dovecot? Thank you all -- Att.

[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.
