[Dovecot] antispam plugin problem
by Eugene 01 Nov '08

01 Nov '08

Hi people! (Especially Johannes, probably =) I recently switched to DSPAM + antispam plugin combination. Mostly I am happy but there is a problem with calling dspam-exec in order to relearn the messages. Moving messages to spam folder does not work, giving the error message 'Failed to call dspam' to client. I tried to add some debug output and here are the results: This is the output of debug("calling dspam: %s %s %s %s %s %s %s", argv[0], argv[1], argv[2], argv[3], argv[4], argv[5], argv[6]); (debugv(argv) does not produce any output for some reason) Oct 26 02:37:12 qqqqq imap: antispam: calling dspam: /usr/contrib/bin/dspam --source=error --class=spam --signature=490387db858421194018847 --user genie (null) This is the captured output of forked process Oct 26 02:37:12 qsar imap: antispam: dspam returned: ^APdata stack: Out of memory when allocating 1073741840 bytes If I understand correctly, this message is produced by dovecot before it should have launched dspam executable. I don't know why it needs 1GB of stack space for that. Changing dspam to dspamc does not help. Interestingly enough, launching 'sendmail' in mailtrain mode works ok. Do you have any ideas about what is wrong? Best wishes Eugene

[Dovecot] imap dump-capability fails Dovecot 1.1.6

[Dovecot] dovecot expire doesn't work (?)
by LÉVAI Dániel 31 Oct '08

31 Oct '08

Hi! I'm using dovecot-1.1.5 and trying to make the expire plugin work. What I've configured in dovecot.conf is the following: protocol imap,pop3,lda { mail_plugins = [...] expire } dict { expire = db:/var/dovecot/expire/expire.db } plugin { expire = spamassassin/SPAM 2 spamassassin/HAM 2 expire_dict = proxy::expire } I have a sieve rule, to copy certain messages to my "spamassassin/SPAM" folder. Then I want to expire those messages after 2 days (I think I've configured that under the plugin{} section in dovecot.conf). So the actual message saving is done by the dovecot's deliver, but I have the plugin loaded under the "protocol lda {}" section too. So I thought now I just have to wait 2 days, and run the expire-tool, and then it will expire the messages. Now I have three messages dated back to 10.25, but running the expire-tool outputs nothing. # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Nothing in the logfiles, and nothing on the console. I have the /var/dovecot/expire directory: # ls -la /var/dovecot/expire/ total 1640 drwx------ 2 root wheel 512 Oct 26 19:47:53 2008 ./ drwxr-x--- 3 root wheel 512 Oct 27 07:57:42 2008 ../ -rw------- 1 root wheel 24576 Oct 27 13:00:01 2008 __db.001 -rw------- 1 root wheel 57344 Oct 27 13:00:01 2008 __db.002 -rw------- 1 root wheel 270336 Oct 27 13:00:01 2008 __db.003 -rw------- 1 root wheel 98304 Oct 27 13:00:01 2008 __db.004 -rw------- 1 root wheel 49152 Oct 27 13:00:01 2008 __db.005 -rw------- 1 root wheel 32768 Oct 26 19:47:37 2008 expire.db -rw------- 1 root wheel 10485760 Oct 27 14:22:08 2008 log.0000000001 It contains the familiar BDB files, so I think it works, although the expire.db's modify time is yesterday, but deliver saved some messages also today to the spamassassin/SPAM folder. What could be the problem? Am I missing something? Thanks! Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] Problem with Dovecot 1.1.4 and dovecot-antispam 20080829
by Guillaume Hilt 31 Oct '08

31 Oct '08

Hi there, I'm running a server under Gentoo 64 with postfix 2.5.5, Dovecot 1.1.4-r1 and Dovecot-antispam 20080829 (all are the lastest versions availables under Portage). I ran into a problem when I log in to my mailbox : Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Loading modules from directory: /usr/lib64/dovecot/imap Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Module is for different version 1.1.1: /usr/lib64/dovecot/imap/lib90_antispam_plugin.so Oct 30 10:39:23 ks29138 dovecot: Fatal: IMAP(hiltg): Couldn't load required plugins Is there another version for Dovecot 1.1.4 out there or must I go back to 1.1.1 ? Thanks, Guillaume

[Dovecot] Dovecot read only for users
by JC 31 Oct '08

31 Oct '08

All, I have hopefully a base question. How do you give users only read access to their inbox and folders? If I use chmod 600 they have full access. If I do a 400 they have read access but cannot access their inbox. The config file is the out of the box config other than advertising IMAP and IMAPS. Any help will be appreciated. Thanks.

[Dovecot] Startup info message
by Athan Dimoy 31 Oct '08

31 Oct '08

Hi folks, I'm using the latest Dovecot 1.16 with Postfix for my FreeBSD box. Since v1.1.4 (if i remember correctly), the following message is displayed whenever starting Dovecot. "Info: If you have trouble with authentication failures, enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork" Besides that, Dovecot works great but I wonder what this message is all about. I've searched wiki and mailing list but didn't find anything related. PS: I removed Dovecot removing all stalled files and directories and reinstalled it from scratch. Still the message is displayed whenever it starts. Any idea? Athan

[Dovecot] SIGBART/SIGSEGV while SELECTing virtual folder
by Lars Noschinski 30 Oct '08

30 Oct '08

Hello! I just installed Dovecot's latest nightly build (20081020) and tried the virtual folder features. I started with a really simple "all" folder: | # virtual/all | * | all But selecting this folder causes dovecot to panic (in most cases). While trying to debug this, I got slightly different results and I am not really sure yet if this is just non-deterministic, depends on some cached dovecot data or if there is some difference between the debug build or my rudimentary, unpatched debian package (which lacks the debug symbols). The results below are from a build with --prefix set to a clean, temporary directory. Similar problems occured also with the alpha2 release, which caused me to try the latest nightly build. --------------------------------------------------------------------- % ./sbin/dovecot --exec-mail ext /usr/bin/gdb ./libexec/dovecot/imap GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

[Dovecot] mail_executable's process environment
by Mike Malsman 30 Oct '08

30 Oct '08

Hello, I recently had to get Dovecot 1.1.4 to write to a "pop3/imap-before- smtp" db such that my MTA could permit relay after a successful authentication with Dovecot. The 'pop3' and 'imap' processes are executed only after a successful auth, so replacing them with wrappers which write to the db seemed the natural choice. Lo and behold, someone thought of something like this, as the 'mail_executable' directive exists - neat. Upon inspection of the processes' environment I'm pleased to see that there's a load of useful information in there. However, one essential component in my case is the destination network address, which is missing. I added it with the attached patch, exposed as 'LOCAL_IP'. Works for me. Is this something that would be useful to anyone else? -Mike

[Dovecot] [dovecot] Enable logging of all client commands in dovecot-1.2.alpha3
by Jonathan Siegle 30 Oct '08

30 Oct '08

Hello, I would like to log all IMAP client commands sent to dovecot. The format would be time pid command arguments. I reviewed http://wiki.dovecot.org/Logging and started digging through dovecot-1.2.alpha3/src/master . I don't need this turned on all the time, just enough to see how clients do things and I don't need to see passwords. Any tips would be appreciated. -Jonathan

[Dovecot] benchmark dovecot
by Mathieu Kretchner 30 Oct '08

30 Oct '08

Hello, We would like to do a feed back to this active mailing list. We are working on a migration project from cyrus to dovecot. And we have just completed the benchmark sequence. As I say, this benchmark is here only to show that our old imap server is out to date. I would not be the source of controversy at all, so I try to explain my approach. Because the only thing I found was this old oriented benchmark : http://www.isode.com/whitepapers/mbox-benchmark.html We've tried to do our tests, here you could find our results : http://www-sop.inria.fr/members/Mathieu.Kretchner/dotclear/index.php/2008/1…

[Dovecot] Enh-Req: Mark As Read When Delivered
by Neil 30 Oct '08

30 Oct '08

I'm under the impression bug-reports are supposed to go to the list, so hopefully it's okay if I put in a feature request here too (assuming it's not already implemented; but it doesn't look like it). Basically, all I would like to do is be able to sometimes deliver mail as already mail into mail boxes. Is there some way to do this? If not, could a flag perhaps be added to deliver to do it? (And Sieve; but for now I think procmail still has much higher adoption, and thus having it in deliver would be rather key...) Thanks, -Neil.

[Dovecot] INBOX stored in AFS
by Hans-Werner Paulsen 30 Oct '08

30 Oct '08

Hello, currently we are storing the incoming mail in the user's home directory, which is within a distributed filesystem called AFS (OpenAFS). Accessing the "mbox" file directly (using the distributed filesystem) works fine with mutt, thunderbird, ... To access the INBOX from a machine, which does not have access to this distributed filesystem, we are using IMAP (UW-imap). Now I wanted to check if dovecot can do the job (maybe faster than UW), and I had the following problem: This is my configuration: ------------------------------------------------------------------------------- # 1.1.4: /opt/dovecot-1.1.4/etc/dovecot.conf log_path: /var/log/dovecot ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/keys/imapd.pem login_dir: /var/run/dovecot/login login_executable: /opt/dovecot-1.1.4/libexec/dovecot/imap-login first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=~/.maildir/incoming mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl mbox_dirty_syncs: no mbox_lazy_writes: no mail_executable: /opt/dovecot-1.1.4/libexec/dovecot/afs-token /opt/dovecot-1.1.4/libexec/dovecot/imap auth default: verbose: yes debug: yes passdb: driver: pam args: setcred=yes session=yes dovecot userdb: driver: passwd ------------------------------------------------------------------------------- When I start my imap-client, I see the content of the INBOX, and I can read, delete, ... the different entries. But when new mail arrives dovecot (and my imap-client) will never notice this. And when I quit my imap-client the dovecot imap server will write back its view of the INBOX, and delete this new mail. This seems to be a problem related to AFS. I poked in the dovecot code and have the following theory: dovecot opens the INBOX R/W, dovecot calls "stat" on the INBOX file periodically to look for modifications. But this does not work, because this machine will stat the local copy (AFS cache) of the INBOX as long as this file is still open R/W. My questions: Is it possible to have a configuration, that the INBOX file is not left open when stat-ing this file? Or is it possible to open the INBOX file R/W only when it us locked? Or is it necessary to modify the code?

Re: [Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by seriv＠parkheights.dyndns.org 30 Oct '08

30 Oct '08

Thank you Timo, it was my mistake. In 'plugin {}' section line 'sieve = /var/sievescripts/%n/sieve' worked for both cmusieve and sieve plugins. Command 'fileinto "INBOX/foo/bar"' with private namespace configuration you proposed - also worked in both plugins. I suspected that they have different behavior: cmusieve saved message into INBOX/foo/bar, while sieve - into foo/bar as in the deliver log I'm pasting here. But both messages were filed into the same mail folder. Difference in the logging, I think, is not a big problem. --- ls -l Maildir/.foo.bar/new total 8 -rw------- 1 seriv seriv 513 Oct 30 01:57 1225331850.M790093P1351.sisyphus.office.omniti.com,W=526 -rw------- 1 seriv seriv 518 Oct 30 01:59 1225331966.M468658P1400.sisyphus.office.omniti.com,W=531 tail -n 18 /var/log/deliver/dovecot-deliver.log --- deliver(seriv): Oct 30 01:57:30 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:57:30 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_cmusieve_plugin.so deliver(seriv): Oct 30 01:57:30 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:57:30 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:57:30 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Executing script /var/sieve-scripts/seriv.sievec deliver(seriv): Oct 30 01:57:30 Info: Namespace INBOX/: Using permissions from /home/seriv/Maildir: mode=0644 gid=-1 deliver(seriv): Oct 30 01:57:30 Info: msgid=<20081030015649.B7936140A88(a)sisyphus.office.omniti.com>: saved mail to INBOX/foo/bar deliver(seriv): Oct 30 01:59:26 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:59:26 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_sieve_plugin.so deliver(seriv): Oct 30 01:59:26 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:59:26 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:59:26 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:59:26 Info: sieve: using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: opening script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: executing compiled script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: msgid=<20081030015911.576FC140A88(a)sisyphus.office.omniti.com>: stored mail into mailbox 'foo/bar' -- WBR, Sergey Ivanov. ----- "Timo Sirainen" <tss(a)iki.fi> wrote: > On Wed, 2008-10-29 at 20:31 +0100, Stephan Bosch wrote: > > sergey ivanov schreef: > > > Hi Stephan, > > > Thank you for quick fix.

Did you try dovecot-sieve-1.1 with dovecot 1.2 to verify? I'll ask Timo about this. What is the configuration of your mail store.

[Dovecot] FTS index generation
by Dave McGuire 30 Oct '08

30 Oct '08

Hi folks. I'm experimenting with the Squat plugin. I can execute search commands via direct interaction with IMAP, but I never see the expected dovecot.index.search index file appear in the spool. I'm concerned that I've misconfigured something that is preventing the creation of those indices. Is there a facility to have the squat plugin generate debugging messages so I can see what it's doing? Thanks, -Dave -- Dave McGuire Ahh, you voted for Bush? Port Charlotte, FL Happy now?

[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

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. 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 .

[Dovecot] Bug? auth(default) Authentication client gave a PID of existing connection
by Brandon Lamb 26 Oct '08

26 Oct '08

Hello, My first time on this list, just switched from courier imap/pop3 system to dovecot. Imap part is great, pop3 seems to suffer, been fighting it for a week. Anyway, the reason for this post is that I have seen these pop up in my logs, and on one of my mailheads there were some 50 lines of this dovecot: 2008-10-26 09:33:54 Error: auth(default): BUG: Authentication client gave a PID 15661 of existing connection Is this really a bug or anything to be concerned with? I just installed 1.1.5. I am using Debian lenny/sid on amd64, phenom 9850 4g ram, nfs mounted maildir format xfs storage.

[Dovecot] Dovecot dies with PAM error?
by Jason Walton 26 Oct '08

26 Oct '08

Just setup a new server on the weekend with Ubuntu 8.10 beta, and Dovecot 1.1.4. Every now and then, the IMAP server dies, and won't let users authenticate. It happens about once or twice a day. In /var/log/mail.log, you can see dovecot complaining about critial errors: Oct 21 14:46:16 tachikoma dovecot: imap-login: Login: user=<jason>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS Oct 21 14:46:16 tachikoma dovecot: IMAP(jason): Disconnected: Logged out bytes=769/9124 Oct 21 14:47:15 tachikoma dovecot: auth-worker(default): pam(jason,127.0.0.1): pam_start() failed: Critical error - immediate abort Oct 21 14:47:17 tachikoma dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<jason>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS If I have a look at /var/log/auth.log, I see: Oct 21 14:47:15 tachikoma dovecot-auth: PAM _pam_init_handlers: error reading /etc/pam.d/dovecot Oct 21 14:47:15 tachikoma dovecot-auth: PAM _pam_init_handlers: [Critical error - immediate abort] Oct 21 14:47:15 tachikoma dovecot-auth: PAM error reading PAM configuration file Oct 21 14:47:15 tachikoma dovecot-auth: PAM pam_start: failed to initialize handlers This sounds ominous. If I try to cat /etc/pam.d/dovecot, though, the file is obviously there: jason@tachikoma:/var/log$ cat /etc/pam.d/dovecot #%PAM-1.0 @include common-auth @include common-account @include common-session And restarting dovecot seems to fix the problem. Dovecot WAS running just fine, servicing mail all day long, and then suddenly it won't read the PAM config file, and then it won't let anyone log in until I log in and kill it. Any ideas? My IMAP client is either Thunderbird or Roundcube, if that's relevant.
