Re: [Dovecot] How to run Dovecot as IMAP Proxy?

Hi Timo, Thanks for the response. Apologize, but my responses are going to be a bit lengthy. > I have migrated from uw-imap to Dovecot for POP3 & IMAP service. I run > webmail using squirrelmail. When running uw-imap I used to run > up.imapproxyd on the webmail server for faster responses. After > migrating to Dovecot, I find that up.imapproxyd does not work well > with dovecot. > Why not? Here are my observations. I have around 6000+ mailboxes and roughly the same number of users. Earlier the mail server (running sendmail + uw-imap for POP3 & IMAP) would have around 80 pop3 connections (peak) and around 300 IMAP connections, concurrent. (ps -aef | grep imap | wc -l or ps -aef | grep pop3 | wc -l). There have been cases where I have observed upto 500 concurrent IMAP sessions. The IMAP connections are from a webmail server running Apache with Squirrelmail. The observation was that response was slow & so based on the suggestion on Squirrelmail for performance improvement we have installed up-imapproxyd on the squirrelmail machine. There was a significant improvement in the response times for the users, because of caching. After that I encountered some strange problems of POP3 timing out for users (earlier I did post that problem in this forum). I opened a ticket with Redhat and naturally they refused to support me with uw-imap running. So switched to Dovecot 0.99.x (I run the server on RHEL 4.0 and that is the max version supported by Redhat for that version). Ever since I did that POP3 works fine but now webmail is almost not available to the users. People usually get "connection dropped by IMAP server". However the IMAP server seems to work fine. Checked through manual "telnet <ip.address.of.mailserver> 143 & also through other client such as outlook & Thunderbird. I noticed that while the number of established connections for the webmail to mail server was shown as around 40 to 50 on the mail server, the same is shown as around 700 on webmail server. { netstat -an | grep :143 | grep ESTABLISHED | wc -l }. imapproxyd is configured to listen on port 9143 on the localhost and communicates to the mail server on std port 143. What was really bizzare is that when I check for the number of connections on port 9143 it shows around 8000! netstat -an | grep :9143 | grep ESTABLISHED | wc -l So I disabled the imapproxyd on the webmail & now at least the 50 connections are consistent. However the response is extremely slow and so was contemplating on the idea of trying out using another IMAP Proxy server and hence the question. > I don't understand Databases and don't want to install mysql etc for a > simple thing like IMAP PRoxy. > Do you just want it to proxy everyone to a single destination or to > different servers based on username? If you want everyone to the same > destination, why do you even want to use a proxy? I want to proxy all user to the same server. The idea being as explained above benefit from caching. > My question is can Dovecot be run as a IMAP PRoxy without the hassle > of setting up mysql etc?

If I used a passwd file on the webmail machine, running dovecot as a Proxy how would I configure dovecot on the webmail server? It has to accept connections from the squirrelmail and talk to the mailserver. I can do a rsync of the passwd file from the mail server to the webmail server using a small script whenever the file changes on the mail server. Of course the fundamental question from your response, I guess is, without a proxy why is the webmail slow? If proxy is not my problem, can you pls throw some light on why I am facing performance issues on my webmail alone? Thanks and Regards V S Rao

[Dovecot] IMAP Get Savedate plugin
by Alaa Ibrahim 21 May '09

21 May '09

Hi, I want to add a feature to the fetch command in IMAP, by enabling it to return the save date, when I request the SAVEDATE parameter. I want to use this for my webmail application, so I can show the users the deleted date when they are viewing the Trash folder. I was able to put it directly into the code (patch attached), but I was wondering if there is a way to put it as a plugin instead. Can somebody guide me on how to do that. Thanks a lot. ------------------------- Play the best Flash Games on the web with Maktoob Shams Games. http://games.maktoob.com/

[Dovecot] How to run Dovecot as IMAP Proxy?
by V S Rao 21 May '09

21 May '09

Hi All, I have migrated from uw-imap to Dovecot for POP3 & IMAP service. I run webmail using squirrelmail. When running uw-imap I used to run up.imapproxyd on the webmail server for faster responses. After migrating to Dovecot, I find that up.imapproxyd does not work well with dovecot. I tried to use dovecot as IMAP PRoxy server as per the document http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy I don't understand Databases and don't want to install mysql etc for a simple thing like IMAP PRoxy. My question is can Dovecot be run as a IMAP PRoxy without the hassle of setting up mysql etc? I use /etc/passwd for auth on the actual dovecot server running IMAP & POP3. Thanks V S Rao

[Dovecot] crypt() failure is possible
by Arkadiusz Miskiewicz 21 May '09

21 May '09

dovecot 1.1.15 in src/auth/password-scheme.c contains: static bool crypt_verify(const char *plaintext, const char *user ATTR_UNUSED, const unsigned char *raw_password, size_t size) { const char *password; if (size == 0) { /* the default mycrypt() handler would return match */ return FALSE; } password = t_strndup(raw_password, size); return strcmp(mycrypt(plaintext, password), password) == 0; } but according to man page crypt() can fail and NULL is returned then. On other hand glibc info page is silent about such failure. The thing is that I'm seeing crypt() failure here with new glibc 2.10.1 built with nss backend for crypt(), so it would be good to handle such case. (crypt failure was due to improper nss packaging but it could also happen if somehow nss file becomes corrupted) -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Hallo list-member, Please ignore my bad english. I cant wright bad but i understand well. I reinstalled my server and have big problems with (V 1.1.11) dovecot now. I work with Ubuntu 9.04 Server and want to use pop and imap with easy configuration. I fetch all my Mails on the server and want to look them up by apple Mail. Until yesterday dovecot only worked after I logged in and did something on the server, for example call "mail" oder call "mail.log". After reinstall yesterday it works no more. The new entry in log is "Internal error". Anything else was before yesterday also. My Error Logs: mail.log: May 19 10:00:38 ubuntu dovecot: POP3(annalein): mkdir(/home/annalein/Maildir/cur) failed: Permission denied (euid=1000(annalein) egid=1000(annalein) missing +w perm: /home/ annalein) May 19 10:00:38 ubuntu dovecot: POP3(annalein): Couldn't open INBOX: Internal error occurred.

Re: [Dovecot] Migration questions...
by Richard Hobbs 21 May '09

21 May '09

Hello again, people, I have been reading all of the emails sent back and forth recently, and reading many web pages, and I have a new draft of my migration plan. If anyone has the time and generosity to read through this latest plan for me and let me know if you spot any potential problems with it, i'd really appreciate it. FYI, we're moving from a Debian 3.1/exim/uw-imapd/qpopper/mbox setup to a Debian 5.0/exim/dovecot/maildir setup, and the final version of this document can hopefully become a useful guide for lots of people in future too, if I get it right :-) Anyway... here's the plan... 1. Install Debian with exim, spamassassin, mysqld (for Horde/IMP) and mailman. Use ReiserFS for the indexes and data. XFS would be second choice for filesystem, and this is something of a religious argument, but Dovecot's own page states that ReiserFS is a better choice, and loads of pages on the Internet say that one or the other is better - there's no clear winner, really, so ReiserFS (the FS we already know and trust) wins the battle. 2. Run an online update. 3. Setup IPMI and monitor it from Nagios. 4. Install HotSaNIC to monitor historical system stats. 5. Install and configure Dell OpenManage Server Administrator (or whatever it's called) to monitor hardware, and make sure we will be emailed if a hard drive fails. 6. Rsync homedirs and inboxes onto new server, ready for initial exim configuration. 7. Configure exim as per existing mail server and test that mailing lists and normal email works. You should now have the existing mail delivery solution on the brand new hardware. 8. Configure Spamassassin as per current configuration and test. 9. Configure mailman as per current configuration and test. 10. Once mail delivery is sorted, add "deb http://www.backports.org/debian lenny-backports main contrib non-free" into "/etc/apt/sources.list" and run "aptitude update && aptitude install debian-backports-keyring && aptitude update". 11. Install dovecot (at the time of writing, this was version 1.1.13-2). 12. Run the conversion utility (use "mb2md.py" from http://wiki.dovecot.org/Migration/MailFormat because "convert-tool" doesn't preserve msg UIDs) to convert all existing "mbox" mailboxes into "maildir" mailboxes, for use with Dovecot. 13. Setup exim to use Dovecot's delivery agent ("deliver") so the indexes are updated on mail delivery instead of when the mailbox is requested and also to use the new maildir format. 14. Setup dovecot for IMAP and POP3 and test. *****THIS IS WHERE THE REPEATABLE SECTION BEGINS***** 15. Stop exim and dovecot services. 16. Rsync homedirs and inboxes onto new server again. 17. Run the conversion utility (use "mb2md.py" from http://wiki.dovecot.org/Migration/MailFormat because "convert-tool" doesn't preserve msg UIDs) to convert all existing "mbox" mailboxes into "maildir" mailboxes. 18. Start exim and dovecot services and test SMTP, Spamassassin, mailman, IMAP and POP3. *****THIS IS WHERE THE REPEATABLE SECTION ENDS***** 19. Once everything is working perfectly, send an email to the entire company instructing them what to do after the outage and arrange an outage and do the following steps as soon as the outage begins: a. Unplug DMZ switch from firewall to make delivered mail wait at the sender. b. Stop exim, IMAP, POP3 and dovecot services on both mail servers. c. Rsync homedirs and inboxes onto new server again. d. Run the conversion utility (use "mb2md.py" from http://wiki.dovecot.org/Migration/MailFormat because "convert-tool" doesn't preserve msg UIDs) to convert all existing "mbox" mailboxes into "maildir" mailboxes. e. Start exim and dovecot services and test SMTP, Spamassassin, mailman, IMAP and POP3. f. Reconfigure my own mail client to point to the new mail server (192.168.2.3). g. Reconfigure firewall to think the mail server is now on 192.168.2.3 instead of 192.168.2.2. h. Prepare an email in webmail somewhere in the world, ready to send to a user on our mail server. i. Plug DMZ switch back into firewall and begin monitoring exim logs to check that mail is being delivered. j. Send the email from webmail and check that is goes through exim perfectly and is sitting in the users Inbox. NOTE: We now have a working mail delivery solution! k. Start dovecot IMAP and POP3 and test both. l. Once exim and dovecot are both working against live mailboxes, tell everyone the outage is over. 20. Install and configure Horde & IMP to access email via IMAP. 21. Reconfigure backup script to make sure new server is backed up. 22. Modify Nagios config to monitor new server. 23. DONE! Thanks in advance, everyone! :-) Richard.

Hi, I just downloaded the dovecot-1.2.rc4.tar.gz to do some tests. I coud compile it and generate the package with no trouble on my Slackware 12.2.0 Then as I wanted to try the patchs available at http://hg.dovecot.org/dovecot-1.2/# I downloaded them and applied at once. When I tried to compile once again I got this error: cmd-thread.o: In function `cmd_thread': cmd-thread.c:(.text+0x219): undefined reference to `mail_thread_type_parse' ../../src/lib-storage/libstorage.a(mail-search-build.o): In function `search_arg_build': mail-search-build.c:(.text+0x10b9): undefined reference to `mail_thread_type_parse' collect2: ld returned 1 exit status make[3]: *** [imap] Error 1 make[3]: Leaving directory `/usr/local/src/dovecot-1.2.rc4/src/imap' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/local/src/dovecot-1.2.rc4/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/src/dovecot-1.2.rc4' make: *** [all] Error 2 I removed the patched folder and untarred it again, but at this time I decided to apply one patch at time just to see witch one gave me the trouble. When the first set of patch ( http://hg.dovecot.org/dovecot-1.2/rev/d42a8623a008 ) was applied I got the same error. Just to confirm it was this set of patch, I applied all the other set of patchs leaving that one not applied and the compilation went out with no trouble. As im not a expert so I am sending this report to the list in order to get it fixed. Best Regards, Carlos Xavier.

[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

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.

[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?

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.

[Dovecot] Problem with domain part in user_query in dovecot 1.1.14
by Konstantin 18 May '09

18 May '09

Hi. I'm using dovecot 1.1.14 with pgsql. I tried to configure dovecot to get the domain part in user_query by specifying different variants of auth_username_format variable such as %Lu, %Lu@%Ld, %Lu-at-%Ld and so on... So dovecot gets domain part in password_query, but not in user_query. I noticed the username is changed like this: kostas(a)mgupb.net->kostas in log. For some reason it happens before user_query so there is no domain part already. So one thing that had worked out for me was commenting the below code in src/auth/auth-request.c: if (strcmp(request->user, value) != 0) { /* remember the original username for cache */ if (request->original_username == NULL) { request->original_username = p_strdup(request->pool, request->user); } auth_request_log_debug(request, "auth", "username changed %s -> %s", request->user, value); request->user = p_strdup(request->pool, value); } I know that it is not so good, but it is working for me, now everything is fine, but I want it working without code deformations. What should I do? Thanks. P.S. Such things were in 1.1.11 from which I upgraded to 1.1.14 last night.

[Dovecot] "Broken mailbox list" with virtual plugin
by Matthijs Kooijman 18 May '09

18 May '09

Hi, I'm using the virtual plugin for a virtual inbox (with dovecot 1.2, r8980), whose dovecot-virtual file looks as follows: INBOX INBOX/Lists INBOX/Bulk INBOX/MaybeSpam Folders/TODO all Everything seems to work fine, but I get the following error in my logfiles: IMAP(matthijs): virtual /home/matthijs/Mail/virtual/INBOX: Broken mailbox list Some investigation of the source code tells me that this error means that there was corrupt data in the index. In particular, the ext_data read from the index was not long enough to contain all mailbox names. Adding some debug code confirms this: ext_size: 187 ext_data: \b0\5\0\0\5\0\0\0E\0\0\0\17\20w\9c\1\0\0\0\5\0\0\0\e9\af\e4I\92\1\0 \0\e7\2\0\0\0\0\0\0\7\0\0\0\b\0\0\0\e8\af\e4IO\3\0\0\5c\5\0\0\0\0\0 \0\8\0\0\0\a\0\0\0\ed\af\e4I\e6\0\0\0j\1\0\0\0\0\0\0\9\0\0\0\f\0\0 \0\3a\b0\e4I1\0\0\0e\0\0\0\0\0\0\0E\0\0\0\c\0\0\0\eb\af\e4I\c8\0\0 \0e\0\0\0\0\0\0\0INBOXINBOX/ListsINBOX/BulkINBOX/MaybeSpamFolders/TO ext_hdr: change_counter=1456 mailbox_count=5 highest_mailbox_id=69 search_args_crc32=2625052695 mailbox: id=1 name_len=5 uid_validity=1239724009 next_uid=402 higest_modseq=743 mailbox name: INBOX mailbox: id=7 name_len=11 uid_validity=1239724008 next_uid=847 higest_modseq=1372 mailbox name: INBOX/Lists mailbox: id=8 name_len=10 uid_validity=1239724013 next_uid=230 higest_modseq=362 mailbox name: INBOX/Bulk mailbox: id=9 name_len=15 uid_validity=1239724090 next_uid=49 higest_modseq=101 mailbox name: INBOX/MaybeSpam mailbox: id=69 name_len=12 uid_validity=1239724011 next_uid=200 higest_modseq=101 virtual /home/matthijs/Mail/virtual/INBOX: Broken mailbox list As you can see in the ext_data dump, the last mailbox name (Folders/TODO) is cut short. I'm not so sure what caused this error. I've just tried removing the index files, which seems to fix the error message. The index file gets recreated and my debug statements show proper output. Another solution is adding an extra file to the folder list, in which case the index will get fixed as well. Perhaps it would be good to recreate the index file when this error is found, instead of complaining? Also, from the code (virtual_sync_ext_header_read in src/virtual/virtual-sync.c) it seems that the last mailbox should be skipped because of this error, but the mailbox works fine. I'm probably not looking closely enough :-) I haven't been able to reliably break the index file with some quick testing (reconnecting, restarting and modifying the mailbox list), but I did manage to break it once (by removing a mailbox from halfway the list, and then adding it again). I couldn't reproduce that, though, since removing a mailbox doesn't always seem to recreate the index for some reason... I've also just upgraded to the latest version, so if this is a bug fixed between r8980 and r9018, then you'll probably not hear from me again :-) I hope all this info helps a bit, I'm available for further debugging and testing (also on IRC, nick is blathijs).

Re: the "dovecot: " at the beginning of the line in the log. I should mention that other applications encounter a similar issue with Fail2Ban -- for example, if you're running Asterisk, you have to alter the log format such that the timestamp is at the beginning of the line: http://www.voip-info.org/wiki/view/Fail2Ban+(with+iptables)+And+Asterisk

[Dovecot] Virtual mailbox plugin, crashing?

Hello, Using virtual mailbox plugin and all of a sudden started getting these. Deleted the indexes from ~/Maildir/virtual/Inboxmail and all was good again. dovecot: 2009-05-10 10:05:44 Error: child 26607 (imap) killed with signal 11 (core dumps disabled) Inboxmail/dovecot-virtual: virtual/All inthread refs x-mailbox INBOX All/dovecot-virtual: * -Archive/ -Drafts/ -Trash/ -Trash/* -Deleted* -Junk* -Spam/ -Sent* all I have had this happen 2 or 3 times now, I thought maybe the first couple were flukes from messing with the dovecot-virtual files, then sometime between last night and now this started to give those errors. I am taking a guess that is it is some kind of indexing issue since just deleting those seems to fix it. Not sure what other info I could send, turning mail_debug = yes didnt give any useful info in dovecot.log

[Dovecot] Unable to subscribe to newly created subfolders under public mailboxes with acl plugin enabled
by Max Ivanov 17 May '09

17 May '09

I've "group" namespace and b2b mailbox under it. I'm unable to subscribe to it and deliver emails there. Here is my problem: if I create subfolder (lets name it "subf") under b2b mailbox I'm unable to subscribe to it until acl plugin is enabled. Even if I put dovecot-acl file in .b2b.subf folder with anyone full rights dovecot-acl-list doesn't get populated with new subfoler. If I put it there manually I'm able to see subf folder in subscribe dialog in TB, but dovecot-acl-list is regulary updated, isn't it? Updated file is missing subf entry again. If I disable acl plugin everything works fine, but I'd like to keep it enabled. Is it a bug or misconfiguration?

[Dovecot] Unable to delete folder in public namespace
by Max Ivanov 17 May '09

17 May '09

I use public namespace for group mailboxes. Users are able to create subfolders , but its impossible to delete them. thunderbird 2.0.0.21 complains: "Cant' rename mailbox to another storage type", both namespaces (private and public) use same storage type, so I believe that it's a namespace problem. Is there any way to move folders between namespaces? Or maybe sieve script or plugin which intercept move command and do the move to some unsibscribible folder in public namespace.
