[Dovecot] Problem with pam/krb5 auth on AIX 5.3
by Jonathan Siegle 20 May '09

20 May '09

I'm using pam to authenticate users against my krb5 realm. Here is the problem scenario: User test2 attempts to login and their password is not expired so dovecot says: 0 login test2 myfavoritepassword 0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in 1 logout * BYE Logging out 1 OK Logout completed. User test1 attempts to login, but their password is expired. So dovecot says: 0 login test1 myfavoritepassword 0 NO d expired User test2 attempts to login and their password is not expired. But dovecot still says: 0 login test2 myfavoritepassword 0 NO d expired If I kill the pid with name "dovecot-auth -w", user test2 can login just fine unless I login with the user test1 before trying user test2. So it seems like something is getting cached. I'm running imap-login out of inetd, in case that matters. In my dovecot.conf, I don't have any caching/authentication variables activated. I don't see anything obvious to type in passdb pam{ } to type. For debug, I've enable pam for telnet and tested that without error. Also, the logs show that test2 This is dovecot revision 9062:694714d59cd9 . Looking at the logs, I see user test2 authenticate correctly in all instances. thanks, Jonathan

[Dovecot] %d does not expand to domain
by Giuliano Gavazzi 20 May '09

Hello, dovecot-1.1.7 on FreeBSD 7.1. Usernames have dot in them (like uname.example for a user in example.com) in dovecot.conf I have: mail_location: maildir:/userhomes/maildirs/%d/%n/Maildir and for authentication: username_format: %Ln In the client, tried with CONE and Mail.app, I put the username as: uname.example(a)example.com So, the authentication works fine, as it extracts the uname.example from the uname.example(a)example.com supplied. The mail_location does not: Apr 27 17:21:26 drum dovecot: imap-login: Login: user=<uname.example>, method=PLAIN, rip=88.149.183.86, lip=88.149.202.106, TLS Apr 27 17:21:26 drum dovecot: IMAP(name.example): Effective uid=1301, gid=1301, userhomes=/userhomes/example.com/uname Apr 27 17:21:26 drum dovecot: IMAP(uname.example): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes Apr 27 17:21:26 drum dovecot: IMAP(uname.example): maildir: data=/ userhomes/maildirs//uname.example/Maildir Apr 27 17:21:26 drum dovecot: IMAP(uname.example): maildir++: root=/ userhomes/maildirs//uname.example/Maildir, index=, control=, inbox=/ userhomes/maildirs//uname.example/Maildir it looks like the %d expands to the empty string. Could this be due to the "." in the username? Thanks Giuliano

[Dovecot] maildir filename with eg. ,S=1000, omitted
by Joseph LP 20 May '09

20 May '09

Hello. I encountered the wiki entry on maildirs not long ago. In it, it is suggested that the use of ,S= and ,W= may improve performance as dovecot does not need to calculate size itself. While my maildir filenames have ,W=, they lack ,S=. I've grepped dovecot.conf, but I can find no option to address this. Regards, Joseph

[Dovecot] Dovecot is emptying Maildir folders
by Alexander Johannes 20 May '09

20 May '09

Hello, i have a annoying problem with dovecot after updating to 1.1.14. Dovecot seems to empty all cur/ and new/ Folders in the Maildir of a particular user several times a day (3 times so far). It leaves only unread messages in their place. All Index-Files are getting updated and reflect the "empty"-State of the Mailbox. A quick look over the logfiles reveals nothing which seems to be relevant to this malfunction. The error_log is empty for the relevant timeframe. There is no Expire/Expunge-Plugin running. Fortunately i have a hourly backup-snapshot to restore the Mailboxes, but this is obviously no solution. How can i debug this problem? Any advice is welcome. System: FreeBSD 7.1-RELEASE, dovecot-1.1.14, dovecot-managesieve-0.10.6, dovecot-sieve-1.1.6 (all installed via the ports-tree), exim-4.69_3 Clients: Thunderbird, Mail.app both IMAP only Regards, Alex

[Dovecot] using postfix+dovecot+squirrell+amavisd and spam folder per user
by ESGLinux 20 May '09

20 May '09

Hi All, As I say in the subject I use postfix, dovecot with squirrellmail as webmail and amavisd as spam control, My problem is that all the spam I catch is send to /var/lib/amavis/virus but I want to send this mails to the spam folder of each user. This way the user can see the mails and determine if they are really spam or false positive. I dont know exactly what element of the system is the responsible to do that (dovecot, amavis, posttix) any suggest? (although only be the initial point to look for it) Thanks in advance ESG

[Dovecot] pop3 gives a permission denied error on chdir
by Kenneth Gonsalves 19 May '09

19 May '09

hi, I am running debian lenny standard install and dovecot also as a standard install. I have a problem with POP3 access. The error message is: May 19 09:16:10 greenchilly dovecot: chdir(/home/vmail/example.com/john) failed with uid 5000: Permission denied May 19 09:16:10 greenchilly dovecot: child 26253 (pop3) returned error 89 May 19 09:16:10 greenchilly dovecot: pop3-login: Login: user=<john(a)example.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I have looked at the archives and see that the problem has been reported before, but cannot find any solution. Dovecot as LDA has no problem accessing and writing mails to the directory as UID 5000. I suspect that it is trying to access some other directory and the error message is misleading. The directory /home/vmail/example.com/john is owned by user vmail with UID 5000.

[Dovecot] Virtual users, local delivery via LDA and LDAP troubles
by Konstantin Khomoutov 19 May '09

19 May '09

We're investigating the possibiliy to migrate our mail system from Sendmail+Cyrus to Sendmail+Dovecot. The system must use authentication against Windows AD (supposedly using LDAP) and must use virtual hosting. So far we managed to work around a bug reported in [1], and IMAP/POP3 authentication on LDAP works OK. LDAP auth is set up using binds (Cyrus and Ejabberd authenticate against the same LDAP server without problems). As we use virtual users, userdb is set to be "static" in a standard way: userdb static { args = uid=10513 gid=10513 home=/var/local/dovecot/%u } After verifying IMAP/POP3 authentication works, I've set up the Dovecot LDA to deliver mail for domain users. This exposed another problem which I don't understand: the delivery program tries to figure out whether the user exists (which is perfectly sensible), it talks to the "master" authentication process which seemingly uses passdb backend to search LDAP. But this fails with the message "passdb doesn't support lookups, can't verify user's existence". [2] suggests it's auth binds that prevent this scheme from functioning correctly, but we can't stop using auth binds as Windows AD doesn't store users' passwords in any way sensible for external consumption. This would also pose unnecessary security risk on the domain, as the account used for initial binding should have had rights to read passwords, and its credentials are placed in the Dovecot configuration file in clear text. I read about "allow_all_users" in [3], but our Sendmail doesn't check whether the target user exists and we don't want to implement this as it logically pertains to the program which actually manages users' mailboxes -- Dovecot in our case. Is there a way to solve the problem at hand within the specified constraints? 1. http://dovecot.org/pipermail/dovecot/2009-May/039540.html 2. http://www.mail-archive.com/dovecot@dovecot.org/msg09449.html 3. http://www.mail-archive.com/dovecot@dovecot.org/msg08848.html

[Dovecot] what is deliver(1.1.10) doing in /tmp
by Pawel Eljasz 19 May '09

dear all, first part of log snippet is to show a bit of contrast, to me it's peculiar situation it's about messages between local users, actually one user, when I use command line mailx or anther local account to send to A_local user - ok second part is this weir error, it's selinux which prevents deliver write to /tmp, I believe thsese messages are from A_local user cron jobs(to himself) why would dovecot act differently in these scenarios, why would it need /tmp one time and not need it another May 19 14:32:29 whale postfix/pickup[9588]: 725F08F95500: uid=0 from=<root> May 19 14:32:29

[Dovecot] Segfault in deliver server
by Sascha Wilde 19 May '09

19 May '09

Hi Timo, Hi list, I finally got along to test the current dovecot 1.2 with our Kolab Server. And I'm very excited to see all the cool ACL and shared name spaces stuff upstream, thanks a lot Timo! Anyway I just stumbled across a new bug using our metadata-plugin (which in turn uses the dict back end): Making a few annotations requests after another it stops working. dovecot.log sais something like: Feb 03 11:58:21 burlywood3 <info> dovecot[10486]: IMAP(4(a)burlywood3.rgb): metadata_get_metadata_entry: dict key=shared//kolab/var/dovecot/spool/4@burlywood3. rgb/home/maildir/.Calendar//vendor/kolab/folder-type Feb 03 11:58:21 burlywood3 <error> dovecot[10486]: child 10503 (dict) killed with signal 11 Feb 03 11:58:21 burlywood3 <error> dovecot[10486]: IMAP(4(a)burlywood3.rgb): read(/kolab/var/dovecot/run/dict-server) failed: Connection reset by peer Feb 03 11:58:21 burlywood3 <critical> dovecot[10520]: Fatal: dup2(3) failed: Bad file descriptor Feb 03 11:58:21 burlywood3 <error> dovecot[10486]: child 10520 (dict) returned error 89 (Fatal failure) Feb 03 11:58:21 burlywood3 <critical> dovecot[10486]: Panic: file ioloop.c: line 38 (io_add): assertion failed: (fd >= 0) (END) I attached gdb to dict and got this: Program received signal SIGSEGV, Segmentation fault. array_idx_modifiable_i (array=0x38, idx=0) at array.c:10 10 pos = idx * array->element_size; (gdb) bt #0 array_idx_modifiable_i (array=0x38, idx=0) at array.c:10 #1 0x0805e9a2 in sql_pool_unlink (ctx=0x80fb670) at sql-pool.c:64 #2 0x0805ea24 in sql_pool_new (pool=0x80f9470, db_driver=0x80dd498 "sqlite", connect_string=0x810ad78 "/kolab/var/dovecot/lib/metadata-dict.sqlite") at sql-pool.c:97 #3 0x0805bb3c in sql_dict_init (driver=0x80f9ae0, uri=0xbfce9f76 "/kolab/etc/dovecot/metadata-dict.conf", value_type=DICT_DATA_TYPE_STRING, username=0x80fb910 "4(a)burlywood3.rgb") at dict-sql.c:86 #4 0x0805c9ca in dict_init (uri=0xbfce9f6f "sqlite:/kolab/etc/dovecot/metadata-dict.conf", value_type=DICT_DATA_TYPE_STRING, username=0x80fb910 "4(a)burlywood3.rgb") at dict.c:87 #5 0x0805a1b1 in dict_client_connection_input (conn=0x80fb8d0) at dict-server.c:407 #6 0x0806637c in io_loop_handler_run (ioloop=0x80f8a80) at ioloop-epoll.c:202 #7 0x080652fd in io_loop_run (ioloop=0x80f8a80) at ioloop.c:338 #8 0x0805a42d in main () at main.c:122 (gdb) li 5 6 void *array_idx_modifiable_i(struct array *array, unsigned int idx) 7 { 8 size_t pos; 9 10 pos = idx * array->element_size; 11 if (pos >= array->buffer->used) { 12 /* index doesn't exist yet, initialize with zero */ 13 buffer_append_zero(array->buffer, pos + array->element_size - 14 array->buffer->used); (gdb) p array $1 = (struct array *) 0x38 (gdb) p *array Cannot access memory at address 0x38 (gdb) up #1 0x0805e9a2 in sql_pool_unlink (ctx=0x80fb670) at sql-pool.c:64 64 next_ctx = SQL_POOL_CONTEXT(ctx->prev); (gdb) p *ctx $2 = {module_ctx = {reg = 0x0}, prev = 0x0, next = 0x810d2b0, pool = 0x80f9470, refcount = 0, key = 0x80fb638 "sqlite\t/kolab/var/dovecot/lib/metadata-dict.sqlite", orig_deinit = 0x805f229 <driver_sqlite_deinit_v>} (gdb) li 59 prev_ctx->next = ctx->next; 60 } 61 if (ctx->next == NULL) 62 ctx->pool->unused_head = ctx->prev; 63 else { 64 next_ctx = SQL_POOL_CONTEXT(ctx->prev); 65 next_ctx->prev = ctx->prev; 66 } 67 ctx->pool->unused_count--; 68 } (gdb) c Continuing. Program terminated with signal SIGSEGV, Segmentation fault. The program no longer exists It's quite possible, that we got any details in the usage of the dict back end wrong, but I guess that in any case the dict server shouldn't segfault... cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Multiple dovecot versions side-by-side
by Max Ivanov 19 May '09

19 May '09

I'm current maintainer of dovecot packages in ALTLinux distro and I plan to make possible to install multiple dovecot versions side-by-side (1.0, 1.1, 1.2) to make upgrade process easier and more robust. Is there any consequences of doing that? I worry about locking maildirs and mboxes, does dovecot handle it correctly if another dovecot process tries to work on same mail location?

[Dovecot] LDA and postfix with recipient delimiter: documentation
by John Fawcett 18 May '09

18 May '09

Just a comment about the documentation for postfix integration when using receipient delimiter and delivery of user+foo(a)domain.ext to user@domain: http://wiki.dovecot.org/LDA/Postfix I had some issues to get this working, so thought I'd share my experience. Dovecot version 1.2.rc3. Postfix version postfix-2.7-20090511. I have no local (unix) mailboxes, everything is delivered to dovecot, so in postfix I have set mailbox_transport = dovecot. In this case the following syntax taken from the docs does not work: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} whereas the following does work: dovecot unix - n n - - pipe flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain} I think that ${domain} is always what is wanted and only when ${nexthop} happens to have the same value as ${domain} - for example when using a transport table entry like this: /etc/postfix/transport domain.ext dovecot: will the ${user}@${nexthop} form be deliverable. Can anyone see a reason for not using always ${user}@${domain} instead of ${user}@${nexthop}? John

[Dovecot] How to manage Seen flags via sieve?
by Max Ivanov 18 May '09

18 May '09

I use public namespace for group mailboxes. If someone sends email from this mailbox , MTA detects it and delivers copy of that message to mailbox/Sent folder, to keep history of all messages available for every group member. I'd like to set Seen flag on all messages that dovecots deliver puts into "Sent" folder. Is it posible somehow?

[Dovecot] 1.1.13 squat core dump

While using 1.1.13 and squat with local pine imap on Solaris 9 I had a random core dump today. I was doing a search in a maildir folder with about 2000 emails.

Re: [Dovecot] LDA and postfix with recipient delimiter: documentation

> Hi John, > no i didnt wrote that, i only have user(a)domain.ext > layout in use currently in my test servers > > -- > Best Regards > > MfG Robert Schetterer > > Germany/Munich/Bavaria > Hi Robert I probably didn't make it clear. The problem with the published syntax is that it does not work for receipient delimiter and delivery to mailbox, except as far as I can see when next_hop is the same as domain, which is not always the case. I think that the documentation should report the syntax with ${domain} instead of ${next_hop}, unless there's something I'm missing, since this should always work. thanks again John

[Dovecot] migration and conversion from courier
by Giuliano Gavazzi 18 May '09

18 May '09

Dear all, back in January I posted about migration from courier and in particular on the script courier-dovecot-migrate.pl. That script had a bug on BSD (or should I say not-Linux?) type systems*. On FreeBSD (6.1) and MacOSX (10.5) it appended a lot of binary garbage at the end of dovecot-keywords files. On a couple of systems I had not actually run the script with the -- convert option, as I had misunderstood the procedure, so those systems, ironically, are the ones that I migrated better... Now to the issue. My final question at the time was (http://dovecot.org/pipermail/dovecot/2009-January/036292.html) can one delete the dovecot-keywords and rerun the script (leaving alone the dovecot-uidlist)? There is a problem if this cannot be done, as those files have the following structure: 0 flag0 1 flag1 ... m binary garbage [optionally followed by more lines like the last] and if a new keyword is added, the file ends up like (this is copy and paste example): 0 JunkRecorded 1 $NotJunk 2 $Junk 3 Redirected 4 ^A<F0># 5 <B0><96># 6 $Forwarded It does not look like a nice thing to me. I doubt though that the script will cope with flags correctly, as in principle will get the flags from an out of date courierimapkeywords, thus missing any new ones. Perhaps the only solution is to have a new script that deletes the garbage lines and renumbers the following ones, so that the above example would become: 0 JunkRecorded 1 $NotJunk 2 $Junk 3 Redirected 4 $Forwarded and then renames all *g files to *e. Thoughts? Giuliano * This bug was fixed back then by Timo who replaced the script on the site http://www.dovecot.org/tools/courier-dovecot-migrate.pl. But there's no note of the change on the site nor was an announcement made to the list, AFAIK.

You'd get this error even if you didn't load quota plugin at all. Also note that it's saying "Not enough disk space", not "Quota exceeded" which is the error message from Dovecot v1.0's quota plugin. > And yet, why does 'quota <user>' replies correctly and Dovecot > doesn't? Looking at quota-tools sources, it seemed to ignore the active-check entirely.
