[Dovecot] TLS timeout with Thunderbird
by Jason Dixon 19 Nov '06

19 Nov '06

I'm trying to get dovecot working with various clients on my new mailserver. I installed the base rc2 that comes with OpenBSD 4.0, then upgraded to rc14 when I ran into problems with TLS and Thunderbird. The server has no problems with Mail.app on my laptop, but any connection attempts from Thunderbird timeout after the TCP handshake. 13:53:41.074438 66.x.x.2.50483 > 38.x.x.248.993: S 3787736038:3787736038(0) win 65535 <mss 1460,nop,wscale 0,nop,nop,timestamp 2064284084 0,sackOK,eol> (DF) 13:53:41.074554 38.x.x.248.993 > 66.x.x.2.50483: S 1565942120:1565942120(0) ack 3787736039 win 16384 <mss 1460,nop,nop,sackOK,nop,wscale 0,nop,nop,timestamp 2681405076 2064284084> (DF) 13:53:41.459434 66.x.x.2.50483 > 38.x.x.248.993: . ack 1 win 65535 <nop,nop,timestamp 2064284084 2681405076> (DF) 13:53:47.028621 66.x.x.2.50483 > 38.x.x.248.993: F 1:1(0) ack 1 win 65535 <nop,nop,timestamp 2064284096 2681405076> (DF) The only thing logged by dovecot is a disconnection event. There is nothing else logged, even with ssl_verbose enabled. Nov 17 14:23:05 colo2 dovecot: imap-login: Disconnected: rip=66.x.x. 2, lip=38.x.x.248, TLS handshake This happens with Thunderbird 1.5.0.4 and 1.5.0.8 on Mac OS X, and Thunderbird 1.5.0.7 on Windows 2000. Any ideas would be greatly appreciated. Thanks, -- Jason Dixon DixonGroup Consulting http://www.dixongroup.net

[Dovecot] Security hole #2: Off-by-one buffer overflow with mmap_disable=yes
by Timo Sirainen 19 Nov '06

19 Nov '06

Version: 1.0test53 .. 1.0.rc14 (ie. all 1.0alpha, 1.0beta and 1.0rc versions so far). 0.99.x versions are safe (they don't even have mmap_disable setting). Problem: When mmap_disable=yes setting is used, dovecot.index.cache file is read to memory using "file cache" code. It contains a "mapped pages" bitmask buffer. In some conditions when updating the buffer it allocates one byte too little. Exploitability: I think it's going to be pretty difficult to cause anything else than a crash, but I wouldn't say impossible. Only logged in IMAP/POP3 users can exploit this. In theory you might be able to exploit this for other users as well by sending them a lot of specially crafted emails, but this requires knowing what dovecot.index.cache file contains. Normally its contents can't be predicted, although perhaps with POP3 users it gets empty often enough that the exploit could be tried. Then again, the exploit requires having at least 4MB cache file, which won't happen with POP3 users before the mailbox has about 170k mails (if I counted right). With IMAP the cache file is used more, so it's easier to fill the 4MB with for example a lot of To-headers. Workaround: Use INDEX=MEMORY so the cache files aren't used at all. Fix: 1.0.rc15 fixes this. You can also use this patch: http://dovecot.org/patches/1.0/file-cache-buffer-overflow-fix.diff

[Dovecot] I/O leak
by Jim Horner 19 Nov '06

19 Nov '06

I upgraded from rc12 to rc14 last night... sifting through the logs I noticed the following. I point this out since it appears dovecot is in high gear bug-fix mode. This issue is not big for me; I rarely stop dovecot. My init.d script for dovecot is basically stop) killall dovecot imap-login I am guessing there might be a more graceful way to stop dovecot? Or rc14 fixed this? I see in rc14 changelog: - rc13 crashed if client disconnected while IDLEing but only user1 was IDLE. Nov 15 21:53:23 myserver dovecot: IMAP(user1(a)arinbe.com): Disconnected in IDLE Nov 15 21:53:23 myserver dovecot: imap-login: Killed with signal 15 Nov 15 21:53:23 myserver dovecot: IMAP(user2(a)arinbe.com): Disconnected Nov 15 21:53:23 myserver dovecot: imap-login: Killed with signal 15 Nov 15 21:53:23 myserver dovecot: IMAP(user3(a)arinbe.com): Disconnected Nov 15 21:53:23 myserver dovecot: imap-login: Killed with signal 15 Nov 15 21:53:23 myserver dovecot: I/O leak: 0x804d7a0 (17) Nov 15 21:53:23 myserver dovecot: I/O leak: 0x804d7a0 (15) Nov 15 21:53:23 myserver dovecot: I/O leak: 0x804d7a0 (19) Nov 15 21:53:30 myserver postfix/master[31974]: terminating on signal 15 Nov 15 21:54:02 myserver dovecot: Dovecot v1.0.rc14 starting up Jim

http://dovecot.org/releases/dovecot-1.0.rc14.tar.gz http://dovecot.org/releases/dovecot-1.0.rc14.tar.gz.sig More fixes. "Duplicate header extension keywords" is the only known problem (or if I forgot something, remind me). I'll try to figure out a way to reproduce it easily and then get it fixed. * LDAP: Don't try to use ldap_bind() with empty passwords, since Windows 2003 AD skips password checking with them and just returns success. * verbose_ssl=yes: Don't bother logging "syscall failed: EOF" messages. No-one cares about them. + Dovecot sources should now compile without any warnings with gcc 3.2+ - rc13 crashed if client disconnected while IDLEing - LDAP: auth_bind=yes fixes - %variables: Fixed zero padding handling and documented it. %0.1n shouldn't enable it, and it really shouldn't stay for the next %variable. -sign also shouldn't stay for the next variable. - Don't leak opened .log.2 transaction logs. - Fixed a potential hang in IDLE command (probably really rare). - Fixed potential problems with client disconnecting while master was handling the login. - quota plugin didn't work in Mac OS X

[Dovecot] quota plugin enhancement request
by Michael Tibben 19 Nov '06

19 Nov '06

Hi am having a small issue with the quota plugin In Squirrelmail when a message is deleted, it seems to be copied to the Trash folder *before* it is deleted from the current folder. However if it is a large message being deleted and the mailbox is close to its quota limit, it means dovecot will deny the copy operation as the quota will be exceeded if the message is copied Because of this, I am wondering if it is possible to have an option for the quota plugin to track, but not enforce the quota. This is because I don't require quota enforcement on IMAP, as Postfix will enforce quota on incoming mail anyway. I hope this makes sense... Michael

[Dovecot] Is "Resource temporarily unavailable" an old problem?
by Ricardo Dias Campos 19 Nov '06

19 Nov '06

Hi. I've installed dovecot recently in a Fedora 5 Linux. It seemed to be OK but I begun to get the message "Can't connect to auth server at default: Resource temporarily unavailable". When I get the message, dovecot hangs. The problem is that "temporarily" is not quite true since the only way to get dovecot running again is to restart it. As a matter of fact, I cannot say that it never recovers. What I know is that it is out for a long, long time. Then a new problem arose: the time between hang-ups begun to diminish. Trying to find why I discovered that the number or dovecot-auth processes was too high (last time I got 169 processes, a lot of them <defuncts>). It seems that, if I kill all these processes, it takes more time before it hangs again. I looked up for messages in the Internet and I found a mail exchange between people from this list. The first hint I got was to upgrade dovecot. As I said, I'm using Fedora 5 and the version distributed with it was dovecot-1.0-0.beta2.7.i386. I upgraded it to dovecot-1.0-0.beta8.2.fc5.i386. I couldn't make any direct relantionship between this versions and the ones in dovecot site so I cannot tell what dovecot version I'm using in terms of dovecot site versioning. Any help is welcome. Thanks, Ricardo

[Dovecot] CHANGE REQUEST: Move config files out of main $sysconfdir
by Brian G. Peterson 19 Nov '06

19 Nov '06

Currently, dovecot places it's config files in $sysconfdir In Makefile.am, this is defines as: confdir = $(sysconfdir) It would be far more friendly to an already overloaded /etc/ directory, and easier to locate the files, to follow the now-common convention and place files in $sysconfdir / dovecot / ... on most systems this would mean: /etc/dovecot/ If there is only a dovecot.conf, it doesn't really matter, but when additional config files get added for ldap, sql, sieve, it starts to add up. Some distributions already make this change, but placing this change in the dovecot core would make it unnecessary for downstream packagers to make a change to the core dovecot distribution files.

[Dovecot] updated gentoo ebuild provides dovecot-sieve
by Brian G. Peterson 18 Nov '06

18 Nov '06

I'm hoping that there are some Gentoo users on this list who will chime in on a bug that is near and dear to my heart. We've created an updated Gentoo ebuild that adds a sieve USE flag and builds dovecot-sieve if the use flag is enabled. The gentoo bug is here: https://bugs.gentoo.org/show_bug.cgi?id=141743 and the ebuild is available as an attachment to that bug, or as a patch attachment (in case you're not running rc14, or just prefer the look of a unified diff) Any gentoo users on this list are urged to install from the ebuild/patch on the bug, and *report back* on the bug or this list, so that the Gentoo dev will know that it's safe to add this to portage CVS. Thank You. Regards, - Brian

[Dovecot] Dovecot LDA, LDAP, Postfix and Spawning programs..
by Jorgen Lundman 18 Nov '06

18 Nov '06

Qmail, when using LDAP, a user can specify delvieryProgramPath, or a .qmail file, to launch something like procmail. Qmail correctly setuid() to the uids set for the user in LDAP, as well as set up the common env vars (HOME, USER, MAILDIR). We moved to Postfix but found that it is quite lacking in the features supported when it comes to "virtual" users. No .forward, and if you set up an alternate transport, they are run as "any user but root, nor postfix, nor the virtual-user's uid". And worse, does not even supply the HOME/MAILDIR values to transport delivery plugin. (Forcing it to getpwnam() or similar). I have an option to make my own setuid program to query LDAP (postmap -q would work), setuid() and call, say, procmail. It has been suggested I can use "maildrop" as it can talk to LDAP. However, I picked "Dovecot" as my pop3/imap program due to an irrational dislike of Courier imap. So, if I tried Dovecot-LDA, would it support the user optionally having a ".forward" file, or perhaps the LDAP attribute deliveryProgramPath, or some other way to filter based on subject/body to sort, and/or forward, mail? If it can use LDAP, will it setuid() to the users uid (as set in LDAP, assuming I cook the LDAP conf entries correctly) when delivering(I'd hope so!) and running external filters? I am still running rc10, which works well but flips out regularly. (Previously mentioned 'too many files open' bug, some leaks in locks) I will upgrade when the LDAP changes are deemed stable.

[Dovecot] two assertion failures
by Mikhail Teterin 18 Nov '06

18 Nov '06

Hello! I was able to overcome the earlier-reported problems (of dovecot treating the standard mailboxes in /var/mail/ as directories) by specifying mail_location (continuing to use the 0.99-era dovecot.conf did not work). Then I started seeing assertion-failures like: file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) these disappeared, when I disabled mmap-access (mmap is limited to 1Gb on FreeBSD/i386), although dovecot-0.99 worked... I can now get to my mail again, but every once in a while the following assertion kills the connection: file mail-transaction-log.c: line 273 (mail_transaction_log_close): assertion failed: (log->files == NULL) Please, advise... Thanks! -mi

[Dovecot] Auth checking also the service
by Alex 18 Nov '06

18 Nov '06

Hello everyone. I'm switching to dovecot from courier-imap and after some problems with Apple Mail client, now everything seems to be fine. The only problem that I have not solved yet is to check also the service (pop3, pop3s, imap, imaps) in the authentication phase. In courier-authlib I do this: MYSQL_SELECT_CLAUSE SELECT username, \ password, \ "", \ 1002, \ 1003, \ '/vmail', \ maildir, \ quota, \ name, \ "" \ FROM mailbox \ WHERE username="$(local_part)@$(domain)" \ AND active=1 \ AND $(service)=1 where $(service) can be pop3, pop3s, imap or imaps. Is it possible to do a similar thing in dovecot? Thank you in advance, Alex

[Dovecot] Help needed
by Ricardo Dias Campos 17 Nov '06

17 Nov '06

Hi. Days ago I sent a message to this list asking for help on a problem that seemed to me to be old: dovecot hangs and dovecot-auth posts log messages like: Nov 16 17:04:39 netuno dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Nov 16 17:04:42 netuno dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Unfortunatelly when this happens the only way to recover is to restart dovecot. After I while I begun to clean the dovecot-auth processes (defunct or not) that remain in the process list and the cycle of running/hunging restart from 1 hang a day until it reaches 1 hang each 10 minutes, when I kill dovecot-auth again. I've seen some days ago some messages related to this problem but they were inconclusive, meaning that they didn't point to a solution. Any help is welcome. Thanks. Ricardo

[Dovecot] LDA Question
by Jeff 17 Nov '06

17 Nov '06

I need some advice about replacing maildrop with the Dovecot LDA. I need to replicate a setup that uses postfix+maildrop+spamassassin. We'll be using Dovecot 1rc13. In the current setup, maildrop reads a file called .mailfilter in each user's folder, then call spamassassin according to the user's preferences. The file is simple, and looks like this -- if ( $SIZE > 20971520 ) { EXITCODE=77 echo "Your email was rejected because it exceeded limit of 20 MB" exit } if ( $SIZE < 26144 ) { exception { xfilter "/usr/local/bin/spamc -u user(a)domain.com" } } exception { to "$DEFAULT/Maildir/" } What is the most straightforward way to have 'Deliver' do the same thing, without changing the way that SA gets called? Apologies in advance if this is a boneheaded question. I've been sorting through Sieve documentation and HOWTOs and I see everything but what I need.

[Dovecot] maildirsize update error?
by Maykel Moya 16 Nov '06

16 Nov '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14.

On different mail clients on has to resubscribe..yet there's no such feature w/Pine. Anyone ever had this issue? Also, let me know what sort of info you need me to post in here to get some help on this. Thanks

[Dovecot] 1.0.rc13 released

http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz.sig I'll just keep on making new releases now whenever something important is fixed. Hopefully there shouldn't be many left anymore. Most of the bugs fixed in this release were found by stress testing with my imaptest tool (http://dovecot.org/tools/imaptest.c) If you're interested in knowing how perfectly your Dovecot setup works (especially if you're using NFS), you could try the tool yourself also. I still see one crash with mmap_disable=yes, but it's pretty rare. Will see if I get it fixed before v1.0, but it's not that important. + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying - maildir: Changing a mailbox while another process was saving a message there at the same may have caused the changes to not be made into the maildir, which could have caused other problems later..
