[Dovecot] process imap SIGSEGVs when getting STATUS on mbox box
by Andreas Fuchs 15 Nov '05

15 Nov '05

Hi, I just added an "archive" mbox namespace to my dovecot setup, so that people can put their old mail into a slightly more inode-friendly box. When querying the STATUS on one of these boxes, I got a sigsegv: Program received signal SIGSEGV, Segmentation fault. 0x0000000000454d24 in message_parse_header_next (ctx=0x59e500, hdr_r=0x7fbffff420) at message-parser.c:759 759 if (msg[0] == '\n' || (gdb) bac #0 0x0000000000454d24 in message_parse_header_next (ctx=0x59e500, hdr_r=0x7fbffff420) at message-parser.c:759 #1 0x00000000004297bb in mbox_sync_parse_next_mail (input=0x59e218, ctx=0x7fbffff670) at mbox-sync-parse.c:455 #2 0x000000000042ab9e in mbox_sync_loop (sync_ctx=0x7fbffff590, mail_ctx=0x7fbffff670, partial=0) at mbox-sync.c:118 #3 0x000000000042c187 in mbox_sync (mbox=0x597c70, flags=Variable "flags" is not available. ) at mbox-sync.c:1445 #4 0x000000000042cf3c in mbox_storage_sync_init (box=0x597c70, flags=0) at mbox-sync.c:1770 #5 0x000000000041a000 in imap_sync_nonselected (box=Variable "box" is not available. ) at imap-sync.c:177 #6 0x0000000000413022 in cmd_status (cmd=0x590ab8) at cmd-status.c:68 #7 0x0000000000414319 in _client_input (context=Variable "context" is not available. ) at client.c:338 #8 0x000000000045e4a6 in io_loop_handler_run (ioloop=0x58eca0) at ioloop-poll.c:190 #9 0x000000000045d9cf in io_loop_run (ioloop=0x58eca0) at ioloop.c:230 #10 0x000000000041b841 in main (argc=Variable "argc" is not available. ) at main.c:232 Mail server runs dovecot 1.0alpha4, is an amd64, linux 2.6.8-11 (debian testing).

Hi. Inetd mode is broken as of cvs-20051111 After logging in on POP3 port imap binary is started. Seems like somehow master process receives wrong protocol id and thus starts wrong binary. -- ./lxnt

[Dovecot] problem with content-length and mbox parsing
by Glenn Leavell 15 Nov '05

15 Nov '05

The stars aligned recently such that I sent someone a message that contained a line similar to this in the message body: From glenn(a)usg.edu Thu Jun 20 16:48:11 2002 (Except that there wasn't that space character *before* the From; I've added it here to avoid any problems with this message). Dovecot wrote a copy of the message in my "sent mail" folder under the direction of my imap client. But when I went back to *read* that folder (still through Dovecot), it was broken and was presented as two corrupted mail messages. About a year ago, there was a thread on the list about the fact that Dovecot does not perform >From quoting when writing to mbox folders: http://dovecot.org/list/dovecot/2004-October/004865.html Timo, in that thread you mentioned the following about Dovecot's use of the content-length header: On Tue, Oct 05, 2004 at 05:13:36PM +0300, Timo Sirainen wrote: > Dovecot (and eg. mutt) uses Content-Length header to figure out how > large the message body is, so clients can't mess anything by sending > From-lines. Also Dovecot requires that From-line has correct syntax and > valid timestamp or it's not treated as From-line. In the example above, the message *does* include a valid content-length header after it is initially written, but Dovecot seems to ignore the header when reading the folder, and it treats the "From " line in the body as a message separator. For example, a SELECT on the folder will return "2 EXISTS" even if the single message described above is the only message in the folder. I'm currently at CVS 20051104. Glenn

[Dovecot] IMAP limitation
by Tom Allison 15 Nov '05

15 Nov '05

I was trying to delete a LOT of email messages in one shot from Thunderbird. I selected everything in a folder (>10,000) and then hit DELETE. I received an IMAP error. It clearly implied a limitation to just how many UIDS I can submit on an IMAP request at a time. Is this a limitation of dovecot? (I'm assuming it is). I can work around this, I think, because I haven't found a limitation to retrieving a list of email message UIDS as yet. I could thereby send splices or chunks of that list of UIDS to delete. I ran into this while trying to do a variety of obscene things in my attempts to develop a web mail application. Because of the number of strange tests I have, I don't really "blame" anything since I'm not sure that anyone really expects to delete 10,000 messages at one command.

[Dovecot] TLS negotiation from client fails after openssl upgrade
by Willem Riede 13 Nov '05

13 Nov '05

Is anyone using dovecot on Fedora fc5-devel? I had to rebuild my rpm of alpha4 due to dependencies when I pulled in openssl-0.9.8a (with a whole bunch of other updates). Now when I start my mail client (balsa) it tells me it "Cannot connect to the server: TLS negotiation failed". Dovecot wrote in maillog: "imap-login: Disconnected: rip=1.2.3.4, lip=1.2.3.4, TLS". Does anyone else see that? Can anyone advise me how to debug this? Thanks, Willem Riede.

[Dovecot] Dovecot, Outlook Express and new accounts
by news.gmane.org 12 Nov '05

12 Nov '05

I have come across a strange situation, involving new accounts. I am running Dovecot 0.99.10-5 on Fedora Core 2. Dovecot is configured to use pam for authentication, and the dovecot pam service is configured to use pam_mkhomedir. When an account is created and the user logs in through SquirrelMail, there is no problem. The standard folders are available - Inbox, Drafts, Sent Items and Trash. When logging in through Outlook Express first, it gives the following error:- The server did not respond to this IMAP command before the connection was terminated. Configuration: Account: mail.server Server: mail.server User name: username Protocol: IMAP Port: 143 Secure(SSL): 0 Code: 800ccc0f A packet trace shows the following:- <<< * OK dovecot ready. >>> 008E CAPABILITY <<< * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED STARTTLS AUTH=PLAIN <<< 008E OK Capability completed. >>> 008F LOGIN "username" "password" <<< 008F OK Logged in. >>> 008G IDLE <<< + idling >>> DONE <<< 008G OK Idle completed. 008H LIST "" "*" Connection to host lost. My suspicion that Outlook Express is not intelligent enough to create the folders, although the sudden connection drop might indicate a bug. If it is not a bug, is there a workaround?

[Dovecot] Asserion Failure in Current CVS
by Todd Burroughs 12 Nov '05

12 Nov '05

Just installed the version from CVS as of Oct. 27. I noticed three problems quite quickly: Still seeing "(imap) killed with signal 14" My INBOX closed with "access error" after reading it for a bit. There's nothing in the logs or anything, but this hasn't happened for quite a while now. There where quite a lot of incoming messages at the time and I was marking messages as deleted using pine. After reverting to the last version of dovecot that I was using and restarting pine, it opened quickly (no reindexing) and the deleted emails where marked as deleted. I don't know if this helps much ;-) The rest is a backtrace, etc. of an assertion failure: dovecot: Oct 27 16:58:12 Error: 13481 imap(username): file mbox-sync-rewrite.c: line 393 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) dovecot: Oct 27 16:58:29 Error: child 13481 (imap) killed with signal 6 (gdb) bt full #0 0xffffe410 in ??

[Dovecot] Folders mysterously deleted
by Andy Cravens 12 Nov '05

12 Nov '05

Using alpha 3 on Solaris 9. One of our users reported all folders except his inbox were missing. I went to the server and looked at the logs and could find no indication that a sysadmin had logged in and deleted the folders. Also found no indication of anything unusual in the dovecot log file. Has anybody seen a situation where dovecot deleted folders?

I tried to research this but could not find anything. Apologies if someone already reported this issue. I was running alpha 3 on Solaris 9, and having some timeout issues on lasge mailboxes. Decided to upgrade to rc4 before tweaking anything else. On rc4, when I try to start dovecot, I am getting: dovecot: Nov 10 14:04:56 Info: Dovecot v1.0.alpha4 starting up dovecot: Nov 10 14:04:57 Error: child 18805 (auth) returned error 89 dovecot: Nov 10 14:04:57 Error: Auth process died too early - shutting down dovecot: Nov 10 14:04:57 Error: auth(default): Unknown userdb driver 'passdb' No changes on .conf file.

[Dovecot] dovecot-example.conf error with POP3 UIDL format?
by Shayne Hardesty 11 Nov '05

11 Nov '05

I just installed dovecot 1.0alpha4 on a very busy RHEL4 server with about 1300 users. So far so good, except for the dreaded duplicate emails in outlook for users who use POP3 and have "leave message on server" selected. After searching the archives I found that this is usually related to the UIDL format. The example in the .conf file is this: / # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu / Note that 'v' comes first, then 'u'.. But, right under it, is this: / # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. / In this example (and the next example just under it) 'u' comes first, then 'v'. So is the first example right, in that %08Xv%08Xu is compatible with UW ipop3d, but not outlook? Or is the UW ipop3d example a mistake? For what it's worth %08Xu%08Xv seems to have fixed my users' duplication problems. Shayne

[Dovecot] Moving from mbox to maildir?
by Patrick 09 Nov '05

09 Nov '05

Hi all, New to the list. I have an updated FC4 box with Dovecot version 0.99.14.4.fc4. My mbox size is about 76 megs and growing rapidly because of several high-volume mailing lists I'm subscribed to. I have noticed that over time the performance of the Evoluion/Spamassassin/Dovecot combo deteriorates. Someone on the Fedora users list suggested I have a look at moving to a maildir setup. Reading the docs I can't really figure out what to. Does anyone have a suggestion how I can safely move my mbox setup to a maildir setup? Much appreciated! Regards, Patrick

I try to authenticate using mysql and I always get access denied. I wrote a program in C that connect to the database and it work. I put the code within driver-mysql.c and it failed!!! My question is do you set up anything (SSL?) that could explain this failure. thanks. Here is the code MYSQL *h; h = mysql_init (NULL); if (h == NULL) { fprintf (stderr, "mysql_init() failed (probably out of memory)\n"); exit(1); } if (mysql_real_connect ( h, /* pointer to connection handler */ "localhost", /* host to connect to */ "lyra", /* user name */ "xxxxxxx", /* password */ "lyra", /* database to use */ 0, /* port (use default) */ NULL, /* socket (use default) */ 0) /* flags (none) */ == NULL) { fprintf (stderr, "mysql_real_connect() failed:\nError %u (%s)\n", mysql_errno (h), mysql_error (h)); exit (1); }

[Dovecot] Problem with different case logins
by Roberto Suarez Soto 09 Nov '05

09 Nov '05

Hi, we have a system (Debian sarge) that uses LDAP for user authentication, via pam. We also have virtual users by using a static userdb [1], using the directory structure /var/lib/dovecot/postoffice/%u (i.e., a directory under /var/lib/dovecot/postoffice with the name of the user). The directory /var/lib/dovecot/postoffice belongs to postoffice:mail. IMAP folders, indexes and stuff go here; normal mail goes into /var/mail/%u. We are using dovecot 1.0alpha3 (upgrading to alpha4 soon). Today we've found a grave problem. Let's suppose you have the login "mylogin.domain.com". If you instead use the login "MYLOGIN.domain.com", the authentication works anyway (which is Ok), but dovecot creates a new directory under /var/lib/dovecot/postoffice with the different case, i.e., /var/lib/dovecot/postoffice/MYLOGIN.domain.com (which is not Ok). Afterwards, you can only access this new folder if you use the login with the caps. A new file (we're using mbox) under /var/mail/ with the new name is also created, though I don't understand yet how. We're using Postfix as MTA, and it always delivers to the lower case name. I hope you can understand the problem. If an user logs with a name with just one letter changed from lower case to upper case, all his/her folders and mail will be seemingly gone. Is this a bug or a feature? If the latter, is it possible to change this behaviour, or at least work around it? Thanks in advance. -- Roberto Suarez Soto Allenta Consulting robe(a)allenta.com www.allenta.com

[Dovecot] dovecot and passwd-file migration
by Erick Perez 09 Nov '05

09 Nov '05

Hi, Im using dovecot with passwd-file authentication and would like to provide some kind of interface/script to let the users change their password. currently my passwd-file looks like: user@domain.com:{PLAIN}password I would also like to change the password to the same I use in my Linux user(a)domain.com: {MD5}password ??? What do I need to change in the .conf? Las thing, I just cant find a RPM or Source RPM for dovecot compiled with MySQL support. Our office uses MySQL and not Postgres. doing rpmbuild --rebuild --with mysql to the .src.rpm of dovecot does not work. dovecot fails telling he has no idea of what mysql is. If I get a dovecot with mysql rpm I will move from passwd-file to Mysql auth.

[Dovecot] major pop3+ldap problem with alpha3 and alpha4
by Udo Rader 07 Nov '05

07 Nov '05

hi, For some of our customers we provide a pop3 access, and after an upgrade to alpha3, it is not working anymore. All of our data is ldap based and everything is working as before for our IMAP customers, but our POP3 users fail. Obviously the pop3 login process does not read the data correctly that comes from ldap. after enabling mail_debug, I saw the following error in our log: --------CUT-------- dovecot: Nov 02 18:01:32 Info: pop3(some.one.at.work): mbox: data=/virtual/at.work/home/some.one/mail/:INBOX=/var/mail/some.one.at.work --------CUT-------- The INBOX should be /virtual/at.work/var/mail/some.one.at.work, yet the POP3 process obviously uses the default_mail_env settings. the relevant line in our dovecot-ldap configuration looks like this: -------CUT-------- user_attrs = uid,homeDirectory,MailMessageStore,,uidNumber,gidNumber -------CUT-------- As I said, the IMAP process uses the ldap data correctly. any ideas?

[Dovecot] deleteing e-Mail, quota and dovecot
by Götz Reinicke 07 Nov '05

07 Nov '05

Hi, we run a RHEL4 E-Mail-Server with dovecot-0.99.11-2.EL4.1. we use mbox and most users use imap. So I have set quota for the devices where the user mailfiles are saved. No I'm getting the situation, that users exide there quota but yet not the grace limit and the user isn't able to delete messages. e.g. the the soft limit is 100 MB, the hard limit is 110 MB. So there should be some space to delete unneeded emails. Am i thinking the wrong way? Or how should the quota-system work in this situation? Thanks for any ideas!

[Dovecot] Setup help
by Patrick Ernst 06 Nov '05

06 Nov '05

I'd previously had dovecot running on a Debian server but recently migrated to Suse. The nice, simple setup for dovecot on debian is not as easy using the dovecot sources. My lack of experience I'm afraid! I'd like to continue to use dovecot, especially as my current maildir directories are all set up ready to be use again. On suse (sles9) I have users authenticating by LDAP. In /var/log/dovecot I am getting errors like dovecot: Oct 27 22:17:41 Warning: Killed with signal 2 dovecot: Oct 27 22:28:03 Error: auth(default): LDAP: ldap_simple_bind_s() failed (dn uid=dovecot,ou=people,dc=aro,dc=home): Protocol error The errors also include the same LDAP error but with signal 11 or 15 I cannot get dovecot working. I've tried the 1.0 alpah and also found an earlier version on the suse 10 DVD. Basically I'm looking to use the IMAP server to centrally store emails on our home/business server. Previously we've been downloading mails (POP) from various mail accounts and moving them to dovecot (debian). In the future, I'd like to use fetchmail to do this part and locally deliver mail. My LDAP domain base is dc=aro,dc=home. I generally use this as the local mail/DNS domain as well. I have edited both /usr/local/etc/dovecot.conf and dovecot-ldap.conf. When I run dovecot it fails to start. I wonder if someone, in fairly broad ters could give me the steps for getting dovecot running with LDAP authenticated users? Regards Patrick

[Dovecot] cache
by Lucas 05 Nov '05

05 Nov '05

Hi, I just update from 0.99 to 1.alpha4. I combined with squirrel since several years ago and all was like a charm. Now dovecot is like catching mails. I explain: - I sent an email to my account. I login to webmail and I could see the mail. - Then, I check my mail with an email client through pop3 (vpopmail). - After that the mail isnŽt in the server, but in the webmail appears one msg in Inbox folder and the header. When click to see the msg an error ocurred: Query: FETCH 1 (FLAGS BODYSTRUCTURE) I try this in my config file: mail_never_cache_fields = flags date.sent date.received size.virtual size.physical mime.parts imap.body imap.bodystructure But no success :( Thank you in advance, Lucas

[Dovecot] forcing a default namespace
by Glenn Leavell 04 Nov '05

04 Nov '05

According to the Dovecot documentation, a "default namespace" is defined by simply configuring the namespace with an empty prefix, as in: namespace private { separator = / prefix = inbox = yes hidden = no } But my experience has been that this doesn't provide a true default, and that this namespace will only be selected when the client actually provides an empty ("") prefix. Is there a way to configure a default namespace that will always be chosen no matter what prefix the client provides, as long as there isn't an explicit match? I'd like to be able to have clients find mailboxes in a particular location no matter what they provide as their folder prefix.

[Dovecot] Dovecot 1.0a4 + pam + winbind ?
by Stephen Lee 04 Nov '05

04 Nov '05

Hi, I would like dovecot/pop3 to authenticate against a Windows ADS server. I've got authentication working for Samba and ssh using pam_winbind.so. Here's what my /etc/pam.d/dovecot file looks like: #%PAM-1.0 auth sufficient pam_winbind.so #auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth account sufficient pam_winbind.so session required pam_stack.so service=system-auth session sufficient pam_winbind.so and this is what a portion of the dovecot.conf file looks like: auth default { # Space separated list of wanted authentication mechanisms: # plain digest-md5 cram-md5 apop anonymous mechanisms = plain passdb pam { args = dovecot } userdb passwd { } user = root } To get SSH to authenticate against ADS, the user name has to be prefaced with the domain name like "domain\user1". This is what I get when I attempt to login to Dovecot via Outlook/pop3 with the same naming scheme: Nov 3 20:09:45 server2 dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.3 rip=192.168.0.227 resp=AHZjXGpvYW5uZQBqb2FubmU= Nov 3 20:09:45 server2 dovecot: auth(default): plain(domain\user1,192.168.0.227): Username contains disallowed characters Nov 3 20:09:46 server2 dovecot: auth(default): client out: FAIL 1 user=domain\user1 Nov 3 20:09:46 server2 dovecot: pop3-login: Disconnected: user=<domain\user1>, method=PLAIN, rip=192.168.0.227, lip=192.168.0.3 Dovecot does not like the "\" character and I'm note sure authentication gets past that step to get to the pam phase. Any experiences and suggestions with Dovecot authentication against Windows Active Directory? Thanks, Stephen

[Dovecot] courier2dovecot migration script
by Arto Bendiken 03 Nov '05

03 Nov '05

Howdy, I've just migrated a couple of servers to Dovecot, and am loving it so far. I thought I'd share the courier2dovecot shell script I whipped together (based on the instructions I found in the wiki.dovecot.org migration how-to), for converting Courier-IMAP maildirs to Dovecot format. It can be downloaded from my home page: http://bendiken.net/scripts/ While the script is rather simple, it can save a fair bit of typing when migrating some hundreds of mail accounts... especially since Courier stores some of its own state files recursively in each folder of the maildir hierarchy, making it a real pain to otherwise manually rename or remove all of them. Here's a plain-English summary of what the script currently does, when given a Courier maildir path as an argument: - check that the given path is indeed a valid Courier maildir, and exit if not - rename the file 'courierimapsubscribed' to 'subscriptions', and strip the 'INBOX.' prefix from its contents - recursively rename all of files of the name 'courierimapuiddb' to 'dovecot-uidlist' - recursively delete all of files of the name 'courierimaphieracl', 'courierimapacl' and 'courierimapkeywords' The script will also verbosely print out each action it does, handy for redirecting the output to a log file for a large migration. I hope people about to jump ship from Courier to Dovecot find this useful. If anyone comes up with improvements to the script, please send them my way :-) Arto

[Dovecot] assertion problems w/ 1.0alpha4
by Jeremy Brown 03 Nov '05

03 Nov '05

Hey list, I have been using 0.99.14 for a while now but recently decided to try to upgrade to 1.0alpha4 to get the latest and greatest. I'm building from source myself on a Slackware 10.0 machine. Slackware ships with UW-IMAP configured to keep your inbox in /var/spool/mail and your other folders in ~/. I've been using the same setup for dovecot so that the migration is smooth...so my default_mail_env is set to: default_mail_env = mbox:~/:INBOX=/var/mail/%u I'm able to connect to both pop and imap servers and authenticate myself, but as soon as I attempt to get a listing of my emails my dovecot setting crashes with the following in the mail logs: Nov 3 10:52:40 shallowhal dovecot: imap(jeremy): file mail-index-sync-ext.c: line 155 (get_ext_header): assertion failed: (memcmp((char *)(ext_hdr + 1), ext->name, strlen(ext->name)) == 0) I can trigger this over POP3 just by logging in, then issuing "USER username", "PASS password", and then "LIST". Anyone experienced anything like this before? Any ideas on what might be going on? I can include more debug information (like my dovecot.conf file) if it would help. Jeremy

[Dovecot] How to log POP3 events
by Cliff Hayes 03 Nov '05

03 Nov '05

Hello all, Thanks for your help getting me started. I have Dovecot running now. When I troubleshoot customer email problems, I need to be able to see the number of emails they popped. In /var/log/maillog, Dovecot just tells me that they authenticated, but not what happened after they authenticated. With pop3d, I saw how many emails they popped. Can I set that in Dovecot? I checked the documentation and couldn't find anything. I also turned on the "auth_verbose = yes" and "auth_debug = yes" -- but as the name implies, I only got more authentication info. Nothing about files tranferred. Thanks, Cliff

[Dovecot] Vpopmail authentication problem
by [Mailclub] Laurent Bauer 03 Nov '05

03 Nov '05

Hello, I have a problem setting dovecot-1.0 / vpopmail authentication with virtual users. Here is my dovecot.conf (the part related to vpopmail) : passdb = vpopmail userdb = vpopmail default_mail_env = maildir:/home/domains/%d/users/%n I recompiled dovecot with "verbose" option and keep getting this error : Nov 3 11:10:58 ***** dovecot: auth(default): vpopmail(lb(a)mm.fr): unknown user (lb(a)mm.fr) whatever user/domain/password I am testing (including the correct one, of course) This is in src/auth/userdb-vpopmail.c line 35 : vpw = vauth_getpw(vpop_user, vpop_domain); According to the makefile, the binary was built with -L/home/vpopmail/lib and -I/home/vpopmail/include options ("standard" qmail/vmailmgr/vpopmail installation) so it should be ok ? I checked the permissions by setting a shell for vpopmail user, then 'su vpopmail' and read/write the password.cdb file. What could be wrong ? Has anybody got a sample config file / dovecot version working with vpopmail and virtual users, or an idea of what could be wrong in my config ? Thanks a lot. Laurent

But I wonder how you want to use IMAP. AFAIK, it needs a separate directory for every user anyway. At least the indexes etc. have to be stored somewhere. You should really read doc/mail-storages.txt: "mbox storage requires an IMAP root directory where to store IMAP folders and some other information..." I you can't provide a directory for every user, dovecot is probably not the software for you.

[Dovecot] Still corrupt indexes in 1A4
by Alen Salamun 02 Nov '05

02 Nov '05

Hello All! Well I still have users which almost daily get corrupt dovecot files in their IMAP folders (Maildir style) and are unable to read their mail in this particular folders. When I delete dovecot files in this folder (rm -rf dove*) user can again read all messages. This is regular Linux CentOS 4.2 with SAN storage (boot from SAN) as disks. So this is EXT3 on LVM. BUT it is VERY interesting that than happens only to two users which are connected to the server via slow links (reading via Thunderbird or Squirrelmail). It never happened (now for weeks) to other 10 users which use it localy or at home (on speedy links). It's very hard for me to exactly pinpoint the problem, since it never happens to me. But when it happened to one user again I asked him to send me screenshoot of it. I could see there that SquirrelMail said: "Warning: fgets() [function fgets]: SSL: fatal protocol error in /usr/share/squirrelmail/functions/imap_general.php on line 93." Examining this file this line is in function: --------SQUIRRELMAIL PHP SOURCE------------ /** * Custom fgets function: gets a line from the IMAP server, * no matter how big it may be. * @param stream imap_stream the stream to read from * @return string a line */ function sqimap_fgets($imap_stream) { $read = ''; $buffer = 4096; $results = ''; $offset = 0; while (strpos($results, "\r\n", $offset) === false) { if (!($read = fgets($imap_stream, $buffer))) {<- THIS IS LINE 93 /* this happens in case of an error */ /* reset $results because it's useless */ $results = false; break; } if ( $results != '' ) { $offset = strlen($results) - 1; } $results .= $read; } return $results; } } ------------------------------------------- Looks like dovecot drops connection or something. Well must be related to corrupt dovecot files in particular folder, since deleting them solves the problem. BR, Alen Salamun

[Dovecot] New Fedora/Sendmail Install Assistance
by Cliff Hayes 02 Nov '05

02 Nov '05

Hello everyone, I've narrowed down my problem, so this should be an easy one for some smart person out there. I am moving from an old sendmail/Fedora 2 box to a new sendmail/Fedora 4 box and want to try Dovecot for pop3. The problem is, I can't get it to work. I have 9000 email accounts I will be moving to the new box. I've already tried and failed once. The problem is, Dovecot wants a home directory for each one. We don't use home directories. So, when I try to pop one of the accounts that was moved over, /var/log/maillog shows: Nov 1 14:33:47 sendmail pop3(chayes): mkdir_parents(/home/chayes/mail/.imap/INBOX) failed: Permission denied Nov 1 14:33:47 sendmail pop3(chayes): Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-11-01 14:33:47] -or- Nov 1 14:29:18 sendmail pop3(chayes): mbox: Can't create root IMAP folder /home/chayes/mail: Permission denied Nov 1 14:29:18 sendmail pop3(chayes): Failed to create storage with data: mbox:/var/spool/mail/chayes ******** But if I create folders /home/chayes/ and /home/chayes/mail with user and group set to chayes, then it works. By the way, I've tried about 20 different iterations of the default_mail_env parameter. This is the one I'm using at the moment: default_mail_env = mbox:/var/spool/mail/%u Bottom line is, if Dovecot has to have a home directory, then I guess I'll have to go back to pop3d, which doesn't. Thanks, Cliff

[Dovecot] 1.0.alpha4 released
by Timo Sirainen 02 Nov '05

02 Nov '05

The actual alpha4 release this time. With a few changes since the pre-release. The important changes again: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. - IMAP: We might have sent extra EXPUNGE messages when output buffer got full. This could have caused various sorts of very bad behavior. This is the main reason why everyone should upgrade as soon as possible. - POP3: We sent duplicate replies for LIST command when output buffer got full. Probably caused Thunderbird's duplicate deletion bugs? (Although I thought someone checked that Dovecot's reply was correct when the bug occurred?) - pop3_uidl_format setting is now required to be explicitly set in configuration file for pop3 to work at all. I want to get rid of the old default setting which breaks Outlooks, and simply changing the default would break existing setups. - Multiple passdbs and userdbs of same type can now be added with different parameters. Some people asked about this earlier. - Authentication cache works now with other than SQL and LDAP passdbs. Some passdbs such as PAM require some additional settings to work. See example config file. - Some other fixes to authentication cache related to failure handling and non-plaintext authentication. - deny passdb wasn't working for non-plaintext authentication. New changes since alpha4 pre-release: - imap/pop3 proxy feature was broken - fixed an assert-crash in ostream-file.c that was only in the pre-release And some more changes since alpha3 that I didn't mention before: - zlib plugin updated in http://dovecot.org/patches/1.0/zlib-plugin.tar.gz to be much faster than before - Added ssl_username_from_cert setting. Not actually tested yet, does it work? - epoll was broken with 64bit systems - Added deny password databases. - Dovecot can be run from inetd again - Index breakage/crashfix related to adding new keywords

[Dovecot] Cannot build rpm with mysql support from dovecot.spec
by Erick Perez 02 Nov '05

02 Nov '05

I've been playing for hours with the dovecot.spec file to build --with-mysql. The resulting RPM builds fine but when dovecot runs it does not recognize the passdb mysql statement. I also noted that the spec file has a version of 1.0-stable and rpmbuild complains about an invalid '-' in the version. Being a newbie in rpmbuild, can someone assist me in building for CentOS 4 on i386? standard build options but --with-mysql added. I also tried to install it from sources and it does not work (at least for me). Being a RPM user now I have to clean what the source installation did and i have no clue where the 'make install' placed files. BTW I am trying to build a manual (pdf, html) with the following config and im only stuck with dovecot, the other daemons are ready. Target Server: CentOS 4 with apache, postfix, mysql, dovecot, openwebmail,clamav, clamd, php,zlib,openssh, webmin and samba. All virtual running from mysql where possible, no local users no local storage (all to the mysql db/tables). Not wanted: postgresql, courier,vpopmail,kerberos,sasl,ssl (that might be in manual v2.0 if 1.0 ever sees the light) The system does not have X (no need for fancy graphs) file used: http://www.dovecot.org/nightly/stable/dovecot-stable-20051102.tar.gz RPMs Used: All RPMs that can be located in the CentOS 4 CDs so new users (like me) can do as much as needed without downloading. Devel RPMs: All devel (mysql, pam, openssl) are installed and they are recognized at building time. Your help will be appreciated in this task.

greetings, I'm having a bit of trouble running dovecot, I receive the error; "Fatal: Can't create directory /usr/local/var/run/dovecot: No such file or directory" with an unmodified install save for disabling imap and allowing secure imap and pop3, I uncommented the base_dir in the .conf, although that did nothing. Does anybody have any suggestions? Many thanks, -Ex

[Dovecot] Problems with dual ldap auth
by Stian Jordet 01 Nov '05

01 Nov '05

Hi, I can't seem to figure this out. Is it impossible to use two different ldap auth? It works if I use one ldap and one pam, but I do need to use ldap for both. This is from my config: auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/ldap-virtual.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/ldap-virtual.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root #chroot = #count = 1 #ssl_require_client_cert = no } It works well if I only use one of them (so they seem to be correct), but together, only the last (dovecot-ldap) is used. Anyone see a reason for that? Best regards, Stian

Hi, does current implementation of dovecot-lda supports sieve script like this: require ["notify"]; if header :contains "from" "boss(a)example.org" { notify :high "This is probably very important"; } And if it does, what happens in this case ? Is there any configuration for other notification methods? I didn't notice anything in configuration file. Thanks, Sebastjan

[Dovecot] Usernames and Passwords for Virtual Users Request
by Matt 01 Nov '05

01 Nov '05

A feature I think would be nice. When a single IP hosts email for multiple domains the solution is usually to use the complete email address as the username. I have users that have migrated from Cobalt RAQ's which do not work like that. If a user trys to authenticate with just there username such as "joeb" instead of joeb(a)dirt.com I would like Dovecot to check all the domains it hosts and if it only finds one with the username "joeb" assume thats the one. If multiple domains have the username "joeb" refuse to authenticate without the "@domain" part. Perhaps this is not possible. Sure would be handy though. Oh, it would also be nice to automatically lowercase all usernames before authentication. Matt

[Dovecot] popa3d migration problem
by Janusz Batko 01 Nov '05

01 Nov '05

Hello, I tried to migrate from popa3d to dovecot but I couldn't manage with 'pop3_reuse_xuidl = yes' option. First of all it turned out that the feature is not supported in dovecot for Fedora Core 4 (dovecot-0.99.14-4.fc4). So I downloaded latest stable release of Dovecot but it didn't have this option included too. Then I compiled the newest alpha version (dovecot 1.0.alpha4) and I tried to login with 'pop3_reuse_xuidl = yes' option enabled and I've got in my logfile the following output: Nov 1 00:58:33 sneogg dovecot: pop3-login: Login: user=<test2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Nov 1 00:58:33 sneogg dovecot: pop3(test2): Set pop3_uidl_format setting in config file Nov 1 00:58:33 sneogg dovecot: child 32067 (pop3) returned error 89 And my session was disconnected immediately each time after sucessful authentication.. I tried to set up pop3_uidl_format to MD5 (%m) but it didn't work... Let me ask if there is a possibility to migrate from popa3d to dovecot (by using a proper patch maybe?)? I'd thankful for any response... Janusz

[Dovecot] errors after 1.0a3 -> 1.0a4
by Jakob Hirsch 31 Oct '05

31 Oct '05

Hi, somebody else seeing these? Oct 21 09:14:06 ymmv dovecot: imap-login: Login: user=<xxxx>, method=CRAM-MD5, rip=84.162.151.124, lip=85.214.25.134, TLS Oct 21 09:14:07 ymmv dovecot: imap-login: epoll_ctl(): No such file or directory Oct 21 09:14:07 ymmv dovecot: child 11419 (login) returned error 89 mailbox access fails after that. Had this already yesterday, then downgraded to alpha3 and it worked again, upgraded again and it kept working. Strange thing is, access through squirrelmail works perfect, but using Thunderbird gives these errors. I'm using maildir with epoll and inotify, if that matters.

[Dovecot] [info] Spamcop listing
by /dev/rob0 30 Oct '05

30 Oct '05

Smtp1.song.fi and smtp2.song.fi, our list servers, seem to have gotten listed in the bl.spamcop.net RBL. Spamcop listings are temporary and will time out, and because of occasional major false positives (or perhaps collateral damage?) like this I don't use it to reject mail. Anyone who IS using Spamcop to reject mail has missed much of today's list traffic. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header

[Dovecot] Dovecot Alpha 4
by Marcus Don 30 Oct '05

30 Oct '05

Hi We've been using Dovecot as our primary IMAP and POP3 server for around 70,000 users for a couple of months now. On the whole, we've been very pleased with the performance of Dovecot - and are extremely grateful to the developers! However, we have had a few issues, some of which we have yet to resolve. We chose Dovecot because it was the only IMAP/POP3 server we could find that supported direct mysql authentication and both mboxes and maildirs. With exim as our main SMTP server, we were able to convert the inboxes and imap folders for all 70,000 users from mboxes to maildirs without any downtime whatsoever! For those who are interested, we have a cluster of 5 web/imap servers (running our own webmail software) and a further 5 pop servers all placed behind 2 Zeus load balancers and running RHEL 4 (actually CentOS 4.1). Storage is provided by an EMC Clariion device, which is mounted via NFS onto all servers in the cluster over gigabit ethernet. 1. index files The main problem has always been the index files becoming corrupted. This seems to have improved with the Alpha 4 release, but still happens for several users each day. Perhaps it would be possible for Dovecot to just delete index files and re-create them when they are corrupted, rather than just erroring? Also, how do you turn off index files altogether? Even when mail_never_cache_fields is set for all available fields, they still get created. Another issue relating to the index files is that, if a user is deleted and then another user created with the same name, dovecot doesn't have permissions to re-write the index files, because it has a different uid. So, whenever a user is deleted, we have to delete the index files from every machine in the cluster. We could store index files on the NFS device, but this would affect performance (and might cause locking problems). A better solution would be to make the uid one of the variables available in default_mail_env. By naming index files by uid rather than username, this wouldn't be an issue. 2. initgroups() We use an nss-mysql to store all non-administrative system users in a mysql database. We often encounter problems with applications that use the initgroups() function, since this returns all users and groups - which in our case returns masses of data from mysql. When using mysql (or ldap etc) for authentication, it would be useful if there were an option to prevent additional system lookups. At present, we have to comment out the following in /src/lib/restrict-access.c, or the server load goes through the roof: if (initgroups(env, gid) != 0) { i_fatal("initgroups(%s, %s) failed: %m", env, dec2str(gid)); } 3. base_dir permissions bug Since the alpha 4 release, it seems that the permissions dovecot automatically sets for the base_dir are not sufficient to allow the authentication user to access sockets, unless this user belongs to the same group as the login user - which is contrary to the instructions in the documentation. I'm pretty sure this is a bug, but perhaps someone could confirm. 4. authentication caching Also since the alpha 4 release, we have found that, once the authentication cache is full, all subsequent login attempts for users that haven't been cached return "password mismatch". I though this might be a conflict with nscd, but it happens whether nscd is running or not. So, for the time being, we have had to disable the authentication cache. I'd be very keen to hear from anyone who has any feedback on any of the points above.

[Dovecot] Dovecot reports zero messages erroneously
by Chris Spiegel 29 Oct '05

29 Oct '05

On October 11, Mark Farmer reported a problem about not being able to see new mails. I'm running into the same issue. Even though cur/ and new/ contain messages, Dovecot reports that there aren't any. This problem seemed to start happening in alpha3 (and persists in alpha4). When I revert back to alpha2, the messages show up again. It looks like a problem with the dovecot.index* files. When I delete them, alpha4 can serve up the mails just fine, and will in fact keep working for a little while. Eventually (within a few hours, although I'm not sure what causes it), dovecot thinks things are empty again. Like Mark, I'm using Postfix.. I'm not sure if that has anything to do with the problem but I thought it'd be worth pointing out. If there are any specific things you'd like me to do to try to pin down this problem, let me know.

[Dovecot] Some errors with 1.0.alpha4
by Nicolas STRANSKY 29 Oct '05

29 Oct '05

Hi, I'm getting three types of errors with latest Dovecot compiled for x86_64 GNU/Linux Debian. Oct 29 12:47:57 rouge imap-login: unable to dlopen /usr/lib/sasl2/libntlm.so.2: /usr/lib/sasl2/libntlm.so.2: failed to map segment from shared object: Cannot allocate memory Oct 29 12:47:57 rouge pop3-login: unable to dlopen /usr/lib/sasl2/libntlm.so.2: /usr/lib/sasl2/libntlm.so.2: failed to map segment from shared object: Cannot allocate memory I have no idea why there is this error, but it comes each time a user logs in, with no other severe effect. Oct 29 01:28:54 rouge dovecot: imap(glondu): pool_system_malloc(): Out of memory Oct 29 01:28:54 rouge dovecot: child 5642 (imap) returned error 83 (Out of memory) Oct 29 01:38:10 rouge dovecot: imap(glondu): pool_system_malloc(): Out of memory Oct 29 01:38:10 rouge dovecot: child 5639 (imap) returned error 83 (Out of memory) Oct 29 01:49:22 rouge dovecot: imap(glondu): pool_system_malloc(): Out of memory Oct 29 01:49:22 rouge dovecot: child 8839 (imap) returned error 83 (Out of memory) The mailbox for this user is not bigger that 10MB and dovecot mail_process_size is set to default setting so I don't see why there could be a "Out of memory" error. Oct 28 18:00:45 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 Oct 28 18:00:45 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 Oct 28 18:00:56 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 Oct 28 18:00:56 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 This error caused the user's mailbox to be unreadable, and erasing the indexes resolved the problem, but I would have expected Dovecot to have done it itself if the indexes were corrupted ? Hope this feedback helps, -- Nico

[Dovecot] Basic Configuration
by Ashvin Meetoo 29 Oct '05

29 Oct '05

Hi, Been setting up a backup mail server just in case... using FC4... basic configuration... postfix/dovecot... imap pop3... When I send an external email, example(a)gmail.com, everything works well. When I send an internal email, i.e. to another user, user receives a blank email? Everytime he clicks on get mail a new empty email is added... checked /<user>/Mailbox/new folder email is there and header is ok. What can be the matter? Did this thousand times before and even reinstalled FC4... same problem. Also, I have tried: echo test | mail root but mail gives me : No mail for root Help please. __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

[Dovecot] dovecot-lda cvs
by Rene Luria 28 Oct '05

28 Oct '05

I am using dovecot-lda from cvs (checked out on september the 21st) and dovecot 1.0alpha2 (not yet upgraded ok). I have a strange feeling about "redirect" feature. Let's see two sieve scripts examples: # ex1 require ["fileinto", "vacation"]; if header :is ["blabla"] "blabla" { fileinto "blabla"; } redirect "user(a)domain.com"; keep; # ex2 require ["fileinto", "vacation"]; redirect "user(a)domain.com"; keep; In both cases, I redirect mail to an external address, keeping a copy. (this would emulate redirect :copy "user(a)domain.com"; which is still not implemented). In first example I run a test on headers, but not on the second. The effect is that in the second example, the forwarded mail is "complete" (exactly the original one with routing header modified), but in the first one, the forwared mail is completely messed up: no Subject header, and so on. This could be because as tests are run on the incoming mail, the working in memory of the mail is changed, and then, forwarded. So when no tests are run, the mail remains intact. How can I deal with this ? Is there some nice hotfix that would prevent a few (like 100'000) users to kill me ? Best regards. -- Rene Luria

[Dovecot] 1.0.alpha3 plaintext authentication problem
by Sergey Redin 28 Oct '05

28 Oct '05

Hello everyone, Since the upgrade to 1.0.alpha3 I experience a strange problem with plaintext authentication. I successfully login first few (2-5) times after the dovecot restart, and then on a reason I cannot login any more (both via POP3 and IMAP). I tried to find out what could be the reason for this but I failed. Nothing is changed inside the user's home directory or /var/run/dovecot, but I cannot login any more.

[Dovecot] problem with thunderbird
by Alfonso Sparano 28 Oct '05

28 Oct '05

Hi all, I've a problem with thunderbird 1.0.6/7/1.5 and dovecot pop3 I've tried dovecot alpha 3 and 1.0 stable but neither one is capable of downloading mails. Nothing is written into the log. I've tried also to delete dovecot.index* and dovecot-uidlist into the Maildir directory. The cur directory contains more than 8100 messages (single files) Anyone has founded this problem? Alfonso

[Dovecot] Corrupted index cache file [...] invalid record size
by Lorens 28 Oct '05

28 Oct '05

I get this error every single time some of my users log in: Error: POP3(${user}): Corrupted index cache file /${userdir}/dovecot.index.cache: invalid record size The named file seems to be deleted as soon as corruption is found. This only affects some users. I thought the affected users had in common that they are using POP3 in "leave-messages-on-server" mode, and that their mailboxes are big ( > 100 MB). However I've found a few counterexamples, few and far between (not every login) but still. Google's no help, for once :-) Could this be a locking problem, a bug with big Maildirs (counterexamples being few), or what? I know some of my users have had problems logging several IMAP clients into the smae account at the same time, wouldn't put it past some of those with problems to be trying the same with POP. I know that a detected cache corruption is merely that, but I find the error message annoying :-) Configuration: v1.0-stable (0.99.20050712-2 from debian unstable) Maildir only Default locking (nothing mentioned in conf file) Access over NFS mmap_disable = yes (wiki says to disable mmap to use indexes on NFS). Thanks for any pointers.

[Dovecot] hangup with corrupted indexes
by Sergey Redin 28 Oct '05

28 Oct '05

Hello everyone, I remember that Timo wrote in this maillist that if index files are corrupted, dovecot should be OK and just recreate it. So I report here a bug: I have corrupted indexes which make pop3 and imap processes to hangup right after the first list command. The process does not respond and eats 90% of CPU. Just unpack http://redin.info/dovecot-corrupted-index.tgz (10 Kb) into a user's IMAP root (I have mbox storage, but the same thing for maildir with this indexes), do the chown, and try to check the email. I know that the problem can be fixed by removing the index files or using INDEX=MEMORY, but it is claimed that dovecot is failsafe and can deal with any kind of corrupted index files. This is the only reason why I report it here. I have 1.0.alpha4 on FreeBSD 4.11 (installed from ports). Best regards, Sergey Redin.

[Dovecot] Weirdness with authentication/1.0a4.
by Ashley Penney 28 Oct '05

28 Oct '05

Hi, FreeBSD has recently upgraded their port from 0.99 to 1.0a4, and this has caused me an absolute nightmare of a situation. In a nutshell I replaced my conf with the -example, and modified almost nothing. I made some SSL certs and put them in place, left it with imap/pop/pam etc. Whenever users tried to connect to the remote address, cara.untaken.net, I would get: Oct 27 18:31:14 cara dovecot: Dovecot v1.0.alpha4 starting up Oct 27 18:31:33 cara dovecot: imap-login: Login failed: Plaintext authentication disabled: rip=217.206.62.50, lip=217.206.62.50 Oct 27 18:31:33 cara dovecot: imap-login: Disconnected: rip=217.206.62.50, lip=2 17.206.62.50 However, plaintext authenication was most definitely not disabled. Using www.untaken.net/mail/ which is hosted on the same box as dovecot I could get this plaintext failure constantly using cara.untaken.net, but switching to 'localhost' instead would work fine, despite being the same physical machine. I'm baffled at what could cause this, I put my currently conf over at www.untaken.net/dovecot/ just for reference, I've modified various bits now from the default in a desperate attempt to get it working. Has anyone else seen anything like it? -- <EisernLint> i am considering taking pilates classes.

[Dovecot] Shared Folder usage alpha3
by Ralf Zerres 27 Oct '05

27 Oct '05

Dear List, this is my first mail to this list. I'v tried to carefully review all given information towards the Shared Folder subject I could find in the archive / mailing list / wiki. And so far I'm also aware that Timo hasn't put it on the active tasklist for the 1.0 release. Citing the track http://dovecot.org/pipermail/dovecot/2003-October/002493.html I was wandering, wether any further attempt has been made, to use the given functionality for real work. To be more precise, wether anybody has done - delivery of mailboxes to a shared maildir - offering these maildirs through a given namespace Before bothering here without any local experience, I'v set up a dov-server (1.0alpha3) on a debian sid. As an MTA postfix is doing the job. Within postfix I did set up a virtual domain and the needed maps (mailbox, alias). I'm able to deliver successful with the standard postfix functionality to the given filesystem structure (fs=ext3). If it is on any help, I can post the relevant config files. As good practice, all mail is delivered to given mailbox-owner with 0600 permission for the new subdir. Hence, can't be seen by any shared-maildir user (unless owner uid matches:) >From here on I'v tried to switch from debians default postfix delivery-strategy (mailbox_command = procmail -a "$EXTENSION") to given dovcot deliver process (mailbox_command = /usr/lib/dovecot/deliver). The primary aim is to define a strategy to deliver with 0660 rights which will enable group read-write access to the given Mailstore. I have adopted the dovecot.conf enableing a listening socket ... default_mail_env = maildir:/home/%u/Maildir: \ INDEX=/home/%u/MaildirIndex namespace private { separator = / prefix = inbox = yes } namespace public { # the prefix needs to be postponed with the separator prefix = Public/ # the location path given as [<mailbox-type>:]<path>/mailbox location = maildir:/home/SharedMaildirs separator = / inbox = no hidden = no } auth default { ... # using deliver through a socket socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } } } and configured the subsequent dovecot-deliver.conf ... auth_socket_path = /var/run/dovecot/auth-master mail = maildir:%h/Maildir/ umask = 0007 auth_verbose = yes use_syslog = yes just to see, whether a manual call /usr/lib/dovecot/dovecot-deliver -d <user> <testmail would do the trick. Well, I got the delivered mail, but files are not installed with the etimated previledges. Can someone can point me to the clou? Greetings Ralf PS: I also read about posix-acl's support. But my test's didn't allow a successful read ....

[Dovecot] Alpha4 pre-release, please upgrade
by Timo Sirainen 27 Oct '05

27 Oct '05

Please try if http://dovecot.org/nightly/dovecot-latest.tar.gz (or the CVS directly) works with you. I made a lot of changes to dovecot-auth, so I wouldn't want to make alpha4 release without some more testing in different environments. I'll release alpha4 in a few days, but it'll be basically same as this unless more bugs get fixed. Some of the changes include: - IMAP: We might have sent extra EXPUNGE messages when output buffer got full. This could have caused various sorts of very bad behavior. This is the main reason why everyone should upgrade as soon as possible. - POP3: We sent duplicate replies for LIST command when output buffer got full. Probably caused Thunderbird's duplicate deletion bugs? (Although I thought someone checked that Dovecot's reply was correct when the bug occurred?) - pop3_uidl_format setting is now required to be explicitly set in configuration file for pop3 to work at all. I want to get rid of the old default setting which breaks Outlooks, and simply changing the default would break existing setups. - Multiple passdbs and userdbs of same type can now be added with different parameters. Some people asked about this earlier. - Authentication cache works now with other than SQL and LDAP passdbs. Some passdbs such as PAM require some additional settings to work. See example config file. - Some other fixes to authentication cache related to failure handling and non-plaintext authentication. - deny passdb wasn't working for non-plaintext authentication.

[Dovecot] 1.0alpha4: mbox-lock asserts and cores
by Jeff A. Earickson 27 Oct '05

27 Oct '05

Timo, I upgraded from alpha3 to alpha4 yesterday, and I am seeing a few of the following asserts: imap(user): file mbox-lock.c: line 379 (mbox_lock_fcntl): assertion failed: (lock_type == F_UNLCK) Gdb info on a couple of the cores is attached. It looks like the arg lock_type for mbox_lock_fcntl() is not getting passed in correctly, like the enum "enum mbox_lock_type type" in mbox_lock_list() is not getting set or used correctly so that lock_data[type].func is wrong. Hmmm. My setup: Solaris 9, mbox, dovecot built with gcc 4.0.2. The filesystem for INBOXes is NFS mounted from another Solaris 9 system, but the index files reside on local filesystems. My setting for "lock_method = fcntl", per your release notes. I did not change the default setting of "mmap_disable = no" because my index files are local. Jeff Earickson Colby College

Hi, I saw the zlib-plugin reference in the alpha4 ChangeLog notes are searched the list for info about it. The only reference I found was from Timo back in March 2005. Questions: 1) Is this going to become a standard part of version 1.0? 2) Any plans or ability to make it read/write to a gzipped mailbox, or is this possible? Or will it always be read-only? 3) How does a mailbox get gzipped? From within dovecot somehow, or only by external action? Jeff Earickson Colby College

[Dovecot] Two "pre-migration" questions
by Alan Mead 26 Oct '05

26 Oct '05

I have read the migration docs. They seem to relate to migrating from one imap product to dovecot on the same server. I'm interested in migrating my Maildir-formatted email from one server to another. 1. Can I tar my ~/mail directory on serverX.com, untar it on a different physical serverY.com (initially with a different domain name), and still see my mail when I access imap.serverY.com <http://imap.serverY.com> (dovecot's running on serverY.com .. but let me know if there are any tricks that I need to make this work). 2. If I maintain large mailboxes and check my mail frequently, how does the dovecot server load compare to something like apache or Samba? I ask because I have a vanity domain that I mostly use for email and I want to ensure that I can migrate my precious emails to a new service provider. And the provider that I'm considering offers low-cost virtual dedicated servers but meters usage (including RAM and CPU). One of the reasons I have question #1 is that the server name seems to be part of the email file names... amead:/home/amead> ls mail/cur | head -2 2022292282.22297_0.vulcan.rootr.net:2,S 2022312282.3225_0.vulcan.rootr.net:2,S (rootr.net <http://rootr.net> is my current provider, not my vanity domain; vulcan is the name of their mailserver) I don't know what effect this will have, if any? Thanks! -Alan

Hi, im using 0.99 stable in RPM form, Im using this for postfix+dovecot+real unix users, now i tried to enable virtual support with this: protocols = imap pop3 ssl_disable = yes log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info login_user = dovecot mail_extra_groups = mail auth = default auth_mechanisms = plain auth_passdb = pam auth_userdb = passwd auth_userdb = passwd-file /etc/vhosts/userdb auth_passdb = passwd-file /etc/vhosts/passwd The above configuration works for local users but is not working for virtual users, it produces the error: dovecot-auth: Oct 21 00:19:14 Info: PAM: pam_authenticate(erickperez) failed: Authentication failure obviously the user erickperez exists in /etc/vhosts/userdb so PAM will fail. Im using 0.99 release. Thanks, -- ------------------------------------------- Erick Perez Linux User 376588 http://counter.li.org/ (Get counted!!!) Panama, Republic of Panama

[Dovecot] 1.0alpha4: drowning in asserts/cores
by Jeff A. Earickson 24 Oct '05

24 Oct '05

Timo, I have had to drop back to alpha3 because I found a pile of core files on my imap server this morning, from the weekend. They are all from the assert: imap(user): file mbox-lock.c: line 379 (mbox_lock_fcntl): assertion failed: (lock_type == F_UNLCK) I reported this issue to the list last Friday. Help...

[Dovecot] Case of %n (feauture request)
by Alexander Shikoff 24 Oct '05

24 Oct '05

Hello, I'm using dovecot not for a long time but I've newer seen most powerful and handy POP3/IMAP server. Thank Timo for dovecot; thank community for help! I would like to notice that %n is case-sensitive: it always stores user part of login without case conversions. As a result there are some inconveniences with virtual user organization, for example: password_query = SELECT `password` FROM `users` WHERE login = '%u' user_query = SELECT "mbox:/var/mail/virtual/%d/%n:INBOX=/var/mail/virtual/%d/%n:INDEX=MEMORY" AS `mail`, 101 AS `uid`, 101 AS `gid` FROM users WHERE login = '%u' In this example authentication works perfectly but user can not access it's mailbox because all mailbox names are lower-case. I think it would be more handy to make %d, %n and %u aliases lower-case and introduce three new aliases %D %N %U which store values without case conversions. But I'm not enough skilled in C to write a patch... and now I'm waiting for comments on this and answer from the developer. Thanks in advance, Alexander. -- Kind Regards, Alexander Shikoff minotaur(a)crete.org.ua

[Dovecot] dovecot + postfix + freebsd help
by glemme 23 Oct '05

23 Oct '05

Hi. I'm currently setting up dovecot to work with my server. My inboxes from postfix are stored in /usr/var/spool/mail/ and then the username, so for me that would be / usr/var/spool/mail/viktor my homedirectory is /usr/home/glemme/homes/viktor/ so from what i can understand. My settings should be: default_mail_env = mbox:%h/Mail:INBOX:/usr/var/spool/mail/%u But guess what, I am probably wrong. my mailapp tells me my inbox is empty and my log claims this: dovecot: Oct 22 16:39:35 Info: imap(viktor: Effective uid=1015, gid=1004 dovecot: Oct 22 16:39:35 Info: imap(viktor: mbox: data=/usr/home/ glemme/homes/viktor/Mail:INBOX:/usr/var/spool/mail/viktor dovecot: Oct 22 16:39:35 Info: imap(viktor): mbox: INBOX defaulted to /usr/home/glemme/homes/viktor/Mail/inbox dovecot: Oct 22 16:39:35 Info: imap(viktor): mbox: root=/usr/home/ glemme/homes/viktor/Mail, index=/usr/home/glemme/homes/viktor/Mail, inbox=/usr/home/glemme/homes/viktor/Mail/inbox Why is it defaulting from the right INBOX to the wrong one?

[Dovecot] 1.0alpha2: how to reject specific users?
by Jeff A. Earickson 21 Oct '05

21 Oct '05

Hi, In Qualcomm's qpopper, you can specify a list of users to reject at authentication, even if they are otherwise valid, by putting them in a file (/etc/pop.nonauth). I use this to occasionally ban users who bang on the system needlessly until they Get a Clue. I looked thru the wiki.dovecot.org/Authentication pages and didn't see anything like this feature. Does it exist in 1.0? BTW, running 1.0alpha2 in production since Sunday night, working great. Zero core dumps, only minor chatter about "Corrupted index cache file" in the syslog, no problems.

[Dovecot] imaps on alternate ports
by Andrew D. Clark 21 Oct '05

21 Oct '05

I'm trying to test out dovecot 1.0 alpha 3 prior to an upgrade from dovecot-0.99.14, but I cannot get imaps listening on anything other than 993. I've tried putting listen = *:2023 in the global section or in the imap { } section. No luck. What is the proper format for a config that only runs imaps and only listens on a particular port? -- Andrew Clark Campus Network Programmer University of California, Santa Barbara andrew.clark(a)ucsb.edu (805) 893-5311

[Dovecot] alpha4: flock change
by Jeff A. Earickson 20 Oct '05

20 Oct '05

Timo, The comments in dovecot-example.conf regarding lock_method for Solaris users needs to note your change. Your changelog says: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. But there is no warning about this in the file for Solaris users. There should be; it will bite somebody later. Jeff Earickson Colby College

[Dovecot] [PATCH] Support for GSSAPI SASL Mechanism
by Jelmer Vernooij 20 Oct '05

20 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Attached is a patch against current CVS that adds support for the GSSAPI SASL mechanism. It was written from scratch, after reading the patch from Colin Walters against a much older version of dovecot. Other then support for the 'GSSAPI' mechanism, it contains the following changes: - - Added 'auth_krb5_keytab' option for overriding default keytab location. The gssapi library already uses the environment variable KRB5_KTNAME to allow overriding of the keytab location, so I didn't have to make any changes on the login process side. - - Added 'need_passdb' member to mech_module and allow having no passdb's specified if no mechanisms need them (only useful for GSSAPI at the moment) Cheers, Jelmer - -- Jelmer Vernooij <jelmer(a)samba.org> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFDVgaEPa9Uoh7vUnYRAscGAJ9Fa4E5ze5IX3UeAfjwg7kzj5tgtQCcDva7 O5VTeOeJ7zpmHullxQN6q1Y= =60w7 -----END PGP SIGNATURE----- Index: configure.in =================================================================== RCS file: /home/cvs/dovecot/configure.in,v retrieving revision 1.214 diff -u -r1.214 configure.in --- configure.in 23 Sep 2005 13:28:40 -0000 1.214 +++ configure.in 19 Oct 2005 08:25:31 -0000 @@ -118,6 +118,15 @@ fi, want_bsdauth=yes) +AC_ARG_WITH(gssapi, +[ --with-gssapi Build with GSSAPI authentication support (default)], + if test x$withval = xno; then + want_gssapi=no + else + want_gssapi_yes + fi, + want_gssapi=yes) + AC_ARG_WITH(ldap, [ --with-ldap Build with LDAP support], if test x$withval = xno; then @@ -1192,6 +1201,17 @@ ]) fi +have_gssapi=no +if test $want_gssapi = yes; then + AC_CHECK_PROG(KRB5CONFIG, krb5-config, YES, NO) + if test $KRB5CONFIG = YES; then + AUTH_LIBS="$AUTH_LIBS `krb5-config --libs gssapi`" + AUTH_CFLAGS="$AUTH_CFLAGS `krb5-config --cflags gssapi`" + AC_DEFINE(MECH_GSSAPI,, Build with GSSAPI support) + have_gssapi=yes + fi +fi + if test $want_ldap = yes; then AC_CHECK_LIB(ldap, ldap_init, [ AC_CHECK_HEADER(ldap.h, [ @@ -1486,5 +1506,6 @@ echo "Building with IPv6 support .......... : $want_ipv6" echo "Building with pop3 server ........... : $want_pop3d" echo "Building with mail delivery agent .. : $want_deliver" +echo "Building with GSSAPI support ........ : $have_gssapi" echo "Building with user database modules . :$userdb" echo "Building with password lookup modules :$passdb" Index: dovecot-example.conf =================================================================== RCS file: /home/cvs/dovecot/dovecot-example.conf,v retrieving revision 1.155 diff -u -r1.155 dovecot-example.conf --- dovecot-example.conf 16 Oct 2005 14:59:12 -0000 1.155 +++ dovecot-example.conf 19 Oct 2005 08:25:31 -0000 @@ -568,9 +568,13 @@ # automatically created and destroyed as needed. #auth_worker_max_count = 30 +# Kerberos keytab to use for the GSSAPI mechanism.

[Dovecot] Large IMAP operations tend to timeout and cause problems?
by Alen Salamun 20 Oct '05

20 Oct '05

Hello all! I have moved from Courier-IMAP to Dovecot some month ago. It is quite stable on everyday use (1.0alpha4) but it has constant problems with large IMAP/SSL operations. We use Maildir format. For example if I select 400 messages, mark them deleted and use "purge command" in Thunderbird (to actually delete them) TB starts to do something and runs and runs and runs....Then I get script timed out errror and I have to restart TB. That never happened with Courier-Imap. Same thing happens for example moving 1000msgs to another folder or something like that. Another thing is still that from time to time dovecot indexes get corrupted and users can't access some folders. Then I have to delete dovecot* in that Maildir folder and it works again. Any thoughts on that please? BR, Alen

[Dovecot] Alpha1..2.. and 3 with Tru64
by Alfonso Sparano 20 Oct '05

20 Oct '05

Hi all, I've found a little problem to compile dovecot on a tru64 os v5.1. The problem is the lack of the "inttypes.h" into the included header in the project. Without this include the make process will fail because it can't find the uint32 type. So is sufficient to add the line '#include <inttypes.h>' in the src/lib/lib.h of the tgz distribution package.

[Dovecot] passwd and virtual users
by Erick Perez 20 Oct '05

20 Oct '05

Hi, im runnign dovecot 0.99.14 with standard pop3 auth and a default .conf file. Everything works fine. But now I need to enable virtual users for several domains in the same server while keeping the local auth. my postfix is already working for the virtual domains. What do i need to modify to enable /etc/passwd auth (already done) and virtual domains auth? in the virtual part, i have no idea. Thanks, -- ------------------------------------------- Erick Perez

[Dovecot] Failed authentication to a mysql database (bug or PEBKAC?)
by jigen 19 Oct '05

19 Oct '05

Hi, dovecot has a little crazy behaviour connecting to a mysql db: if you specify "127.0.0.1" as host instead of "localhost" it seems to work, also with a password. BUT, if you assign host=localhost without a password, it works too (as Ger Visschers says).... One more question: how I can specify more different mysql-db conteining different users? I try in the following way: passdb sql { args = /etc/dovecot/dovecot-mysql_django.conf args = /etc/dovecot/dovecot-mysql_debord.conf } and also: passdb sql { args = /etc/dovecot/dovecot-mysql_debord.conf } passdb sql { args = /etc/dovecot/dovecot-mysql_django.conf } but it always seems to remember only the last args value and it tries to connect only one db... bye jigen -- jigen <jigen(a)metalabs.org> MeTA~LAbS

[Dovecot] Message not found errors
by Andrew Hutchings 19 Oct '05

19 Oct '05

Hi, I'm getting a very small amount of users getting message not found errors while downloading mail via POP. By the time they inform me and I switch on rawloging for them it works again. Any ideas where this is going wrong? Or at least a way I can diagnose it? It seems to have been happening since Alpha 1. Currently using pre-release of Alpha4.

[Dovecot] Pocket Outlook weirdness
by Vadim Zaliva 19 Oct '05

19 Oct '05

Hi! I am trying to access my IMAP server running dovecot from my Pocket PC running PocketOutlook. I observe very strange behavior: it starts to fetch messages from INBOX and shows list them on the screen as it fetches, then all messages disappear from the screen and it says "fetching folders". After the end of update operation it shows me empty list of messages. Have anybody have seen such problem? In general, are there reports of successful pocket outlook + dovecot users? Any suggestions are appreciated! I really want to make this thing work. Sincerely, Vadim

[Dovecot] v. minor bug alpha4pre
by Andrew Hutchings 19 Oct '05

19 Oct '05

Hi, When upgrading to Alpha4pre I also changed UIDL format from %08Xv%08Xu to %08Xu%08Xv to be in line with future dovecot default. This caused the following error to happen on about 1% of mailboxes: file ostream-file.c: line 370 (stream_send_io): assertion failed: (fstream->io != NULL) Deleting dovecot-uidlist and indexes fixes this so its more of an FYI really. I always delete indexes on an upgrade anyway so I'm pretty sure interpretation of the uidlist file if the problem.

[Dovecot] Moving old files
by Jon 19 Oct '05

19 Oct '05

Hi, I wish to automatically remove mail files not accessed for some time. I have done this in the file system and it works fine although it is a bit slow when the mail client access the mailbox after changes. Are there any way of having dovecot moving the files so that index and subscriptions are kept more same? Can one use Dovecot from the command line? Best Regards - Jon

[Dovecot] POP Question
by Marc Perkel 18 Oct '05

18 Oct '05

After upgrading to Alpha 4 I have two people complaining about a POP problem. Aparently they are getting their email sent to them over and over. They have it set to "leave messages on server" but apparently whatever keeps track of that is broken. So - how is it determined with POP what is new and what is read?

[Dovecot] Numpty question about EXISTS...
by Steve [Dovecot] 18 Oct '05

18 Oct '05

I'm fiddling with Ruby and its IMAP class. I'm trying to write something which (at this stage) can be thought of as a variant on xbiff which doesn't need poll the server to establish the presence of new mail... I'd like to establish a notification when the contents of a folder changes... which is likely to be when a different IMAP client moves a message into a new folder. I've been lead to believe that I can use the "EXISTS" response to trigger the 'new message present in IMAP folder" event in my program... but I don't seem to receive them when I would expect to when connected to my Dovecot server. I get one "EXISTS" message when I call "select" - but that's it - it doesn't seem to notice when another client moves messages in/out of the folder. Are my assumptions about IMAP incorrect - i.e. must I still poll? Can Dovecot be configured to send EXIST responses (or any other form of notification) when messages are moved into a folder? Any hints appreciated. Steve

[Dovecot] Debian - upgrade done, plain text auth fails
by Diederik de Vries 18 Oct '05

18 Oct '05

Hi there, I have a problem concerning authentication of dovecot. Yesterday I did a apt-get update on my Debian Testing machine, which had a new version of Dovecot (common/imap/pop3). It now runs 1.0alpha3 Local authentication works fine (Squirrelmail (IMAP), and local 110 connections work). However: pop3 from outside 127.0.0.1 plain barfs when entering the `u` for `user`. What the ....?: === +OK Dovecot ready. u-ERR invalid POP3 command De verbinding met de host is verbroken. (Connection with host is lost) == However, on localhost: === diedx:/etc/dovecot# telnet localhost 110 Trying 127.0.0.1... Connected to diederik.nl. Escape character is '^]'. +OK Dovecot ready. user died +OK pass nothere +OK Logged in. list +OK 208 messages: 1 1679750 2 22179 3 2116 === Works like a charm.

[Dovecot] Permission denied but works anyway
by Bob Hall 17 Oct '05

17 Oct '05

I've just updated from 99.14 to 1.0.a3 on a FreeBSD box. Everything went fine, except for a bit of flakyness from Thunderbird. When first checking a mail box in Thunderbird (running on Win2k), I get a message saying that the command can't be carried out and the server answered "Permission denied". I click OK and everything works fine. As long as Thunderbird stays open, the message doesn't pop up again. It only happens when I first check the Inbox for a given account. No problems with Eudora on Win2k or mutt on FBSD. I've googled with various keywords but I can't find anything on this. I have an extremely vague recollection of seeing a post on this, but I can't find anything.

[Dovecot] verbose pop3 logging
by Ilo Lorusso 17 Oct '05

17 Oct '05

Hi Im new to dovecot and am looking for some options in the /etc/dovecot.conf to make dovecot a bit more verbose in terms pop3 usage, What ip a user is coming from? How many mails the user downloaded? Timing? Errors occurred while downloading mail?? Is this all possible with dovecot?

I've been trying to get Dovecot 1.0a3 running on OpenBSD 3.7, with little luck. I'm getting the following: Oct 16 17:00:50 mailtest dovecot: pop3(testuser):open(/var/mail/.temp.mail.mailtest.com.7078.43c0f93e9fecb54a) failed: Permission denied Oct 16 17:00:50 mailtest dovecot: pop3(testuser): file_lock_dotlock() failed with mbox file /var/mail/testuser: Permission denied Oct 16 17:00:50 mailtest dovecot: pop3-login: Login: user=<testuser>, method=PLAIN , rip=63.201.8.122, lip=64.4.143.26, TLS Oct 16 17:00:50 mailtest dovecot: pop3(testuser): Mailbox init failed top=0/0, retr=0/ del=0/0, size=0 I've read in the archives that this can be fixed by setting mail_extra_groups = mail in dovecot.conf, but OpenBSD has /var/mail owned by root:wheel mod 755, and /var/mail files owned by fileowner:users mod 600, and no mail group. Anyone know how I can fix this? Jeff Simmons jsimmons(a)goblin.punk.net Simmons Consulting - Network Engineering, Administration, Security "It was on fire when I got here."

[Dovecot] E-mail marked as unread
by Andy Cravens 17 Oct '05

17 Oct '05

I have a problem where an e-mail will be marked as unread even though it has been read. When I click on the message the status changes to "read" however, when I go to check for new mail the status changes back to "unread." If I move the message to the trash folder and then move it back to my inbox, the problems stops. Unfortunately, a different e-mail is affected by this problem a few minutes later. I'm using alpha 3 on Solaris 9 and my client is Mozilla 1.7.7 on Solaris 9. No messages in the log to indicate a problem. Anybody else seen this?

[Dovecot] Invalid Headers
by Brant Fitzsimmons 16 Oct '05

16 Oct '05

Hello all, I have been trying to compare Dovecot to Cyrus and in trying to to migrate some mail from Dovecot to Cyrus I am unable to do so because of an invalid header. The From header is incorrectly written as From> as opposed to the correct From: . Any idea what may be causing this and how to fix it? My setup is Fetchmail->Postfix->amavis-new->clamav->dovecot for dovecot and Fetchmail->Postfix->amavis-new->clamav->cyrus for cyrus. When receiving mail in the cyrus setup I don't have the problem. Any thoughts? -- Brant Fitzsimmons brant(a)bfcomputerconsulting.com ------------------------------------------------------------------- "Strange times are these in which we live when the old and the young are taught falsehoods in the schools of learning.

[Dovecot] A Couple Of Issues (APOP Causes Auth SIGSEGV, Umask Setting Ineffective)
by Sabahattin Gucukoglu 16 Oct '05

16 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm very happy with Dovecot and wish the best for its continued development. It's a true testament to brilliant componentised design and Unix philosophy. Configuration made easy because of the way the file is parsed and a single point of startup make it ridiculously straightforward (and lovely) to administer. But of course, we all already know this ... I'm sorry that I can't provide traces at the moment, I'm working from an optimised set of binaries. (-O3 -march=i586 -fomit-frame-pointer) GCC 3.4.4, Gentoo X86 2005.0, Linux 2.6.13, Glibc 2.6.5. Pegasus Mail 4.30B1 is the client on Win32. Dovecot is still Alpha2 (I will upgrade when Gentoo has updated their ebuild). Of course if you advise I'll look at rebuilding newer versions or patched versions with(out) debug symbols. 1. When I attempt APOP login of any variety on the POP3 server auth dies with signal 11. passwd-file is of course listed as a password database, alongside shadow. I get back "-ERR Internal authentication failure - please try again later." or something like this and all subsequent authentication in that session won't work (of course, auth is dead). The password entry is in /etc/dovecot.secrets (perms=0700,uid=0,gid=0) and looks like: username:{PLAIN}cleartextpassword 2. Umask setting gone strange. I set it, per example comment, to "7077" rather than default of 0077 (just to be precise...). When directories are subsequently created, user owning it doesn't even get read/write permissions (just x) and group gets rw but not x! It has not even to do with my system umask (022) set by login. I've set it to 0000 for now in dovecot (/etc/skel has .mail put in people's homedirs with 0700, so there's no worry, but of course I'd like to see that one fixed). If you need more info please let me know. Hope this is enough. Cheers, Sabahattin - -- If an email tells you to forward it to all your friends, please temporarily forget that I am your friend.

The build stops something like: ssl-proxy-gnutls.c:420: warning: 'gnutls_dh_params_set' is \ deprecated (declared at /usr/include/gnutls/compat8.h:82) ssl-proxy-gnutls.c: In function 'read_rsa_parameters': \ ssl-proxy-gnutls.c:446: warning: 'gnutls_rsa_params_set' is \ deprecated (declared at /usr/include/gnutls/compat8.h:77) make[4]: *** [ssl-proxy-gnutls.o] Error 1 Building with openssl 0.9.8 there are connection errors: dovecot: Oct 15 22:46:48 Error: imap-login: Can't load certificate \ file /etc/ssl/certs/dovecot.pem: error:25066067:DSO support \ routines:DLFCN_LOAD:could not load the shared library Any hints?

[Dovecot] a few questions about my experience with alpha1
by Glenn Leavell 16 Oct '05

16 Oct '05

Hi all, I've just switched from 0.99.10.6 to alpha1 on a Solaris 9 system, and I have a few questions: 1) I'm using "verbose_proctitle = yes" but I don't see the special username or IP address information in the output of ps. I've used: ps -fu dovecot ps -ef | grep dovecot /usr/ucb/ps aux | grep dovecot The process table simply shows the /usr/local/sbin/dovecot, dovecot-auth, and imap-login processes. Is there something else that I need to do, or is there a special way that I should use ps? 2) After sending dovecot a HUP signal, the logs will report something like: Warning: SIGHUP received - reloading configuration And everything seems to work fine. However, *sometimes* after sending a HUP signal, logging will stop indefinitely. Has anyone else noticed anything similar? 3) We use UW in production, and I'm new to any real use of namespaces. Almost all of our clients use the root "~/Mail/" to find their folders (in $HOME/Mail/) and their INBOXes are located in $HOME/.inbox. A few people actually find their folders with the direct path Mail/foldername. So, I'm trying to configure Dovecot to work with any of these roots / prefixes: ~/Mail/ Mail/ "" (empty/blank) I'm using the namespace configuration below, and it seems to work with any of the above prefixes. However, the logging that I see makes me wonder if I'm doing it the best way. Note the attached log file. All of this output was generated with this single IMAP command: A01 LOGIN bozo mypassword Here's my configuration: **************************************************************************** # Default namespace private { separator = / prefix = location = mbox:%h/Mail/:INBOX=%h/.inbox:INDEX=%h/Mail/ inbox = yes hidden = no } # This is the standard ~/Mail/ namespace that our clients tend to use namespace private { separator = / prefix = ~/Mail/ location = mbox:%h/Mail/ hidden = yes } # This namespace is for a few folks who might actually try to # directly access "Mail/foldername" -- as if they were accessing a real # filesystem path. namespace private { separator = / prefix = Mail/ location = mbox:%h/Mail/ hidden = yes } **************************************************************************** So, is this the best way to configure the namespaces for what I'm trying to accomplish? And any pointers on how to interpret what Dovecot is working through with regard to the attached logs would be appreciated. Notice the "Sending log messages too fast, throttling.." message (again, generated from that single login command). What might be causing that? By the way, is there any real difference between the use of %h/Mail and the possible use of ~/Mail in the location fields above?

[Dovecot] Problem with pop3 and alpha3
by aspar＠unisa.it 16 Oct '05

16 Oct '05

Hi all, I have a problem with dovecot-alpha3 and pop3 protocol (on a tru64 5.1a...) In my Maildir/cur there are 8144 mails and if I use pop3 protocol I receive in the output 8146 line instead of 8144. The problem is that 2 mails are duplicated . The output of List command is like: 1 51265 2 261783 . . . 2987 30291 2987 30291 (duplicated line) 2988 16631 . 4601 1231 4602 8921 4602 8921 (Another duplicated line) 4603 1313 I've deleted dovecot.* and dovecot-uidlist in the Maildir path but the problem remains. Suggest? Is a bug? I've tried also to remove the first 1000 messages but the problem now is on the mail number 2635 and not 1987 like I can think.

[Dovecot] Possible bug: why is the owner of home-directory important?
by Qweb - Yavuz Aydin 16 Oct '05

16 Oct '05

Dear all, I am trying to migrate one of our systems to dovecot. We were using uw-imapd in black-box-mode before. Since the home-directory of a user is not unique per definition on our systems, we have kind of a different setup. As an example: I got a user, let's say user1. It's home directory is /local/web/websites/5850844095/www. This directory has the following permissions: # ls -la /local/web/websites/5850844095/|grep www drwxr-x--- 7 www-data g5850844095 4096 Oct 13 12:28 www (user1 is member of the group g5850844095) Why is logging in not working properly? See: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 LOGIN user1 password 1 OK Logged in. Connection closed by foreign host. And in the logfile I see: Oct 13 13:09:47 s1 dovecot: chdir(/local/web/websites/5850844095/www) failed with uid 1020: Permission denied Oct 13 13:09:47 s1 dovecot: child 1527 (imap) returned error 89 However, when I change the permissions on the home-dir to 755, it works. The point is, none of my mailboxes (INBOX or others) are in my home-dir, so why does dovecot need my home-directory? I hope someone can help. PS1 the default_mail_env reads: default_mail_env = mbox:/local/mail/imap/%u/:INBOX=/local/mail/spool/%u PS2 This is on a Debian Sarge (3.1) system. -- Best regards, Yavuz Aydin Qweb Internet Services

[Dovecot] Need help with SQL queries after updating to 1.0a3

I upgraded to 1.0a3 - i have everything in the config migrated over, but I'm unsure about the way i should be querying postgres my db handles virtual accounts only, and is set as such: CREATE TABLE accounts ( local_part VARCHAR(64) NOT NULL, domain VARCHAR(64) NOT NULL, password VARCHAR(64) NULL, home_dir VARCHAR(256) NOT NULL, uid INTEGER DEFAULT '1003', gid INTEGER DEFAULT '1003', active CHAR(1) DEFAULT 'Y' ); so an entry would be something like: user | domain.com | md5('passwprd') | /path/to/maildir/ | 1003 | 1003 | Y I've rewritten the password query as such: password_query = SELECT local_part || '@' || domain as user, password FROM accounts WHERE local_part = '%n' AND domain = '%d' AND active = 'Y' ; but i can't get things to work with the user query user_query = SELECT home_dir AS home, uid, gid FROM accounts WHERE local_part = '%n' AND domain = '%d' ; can anyone point me in the right direction? the docs in the distribution aren't very clear, and the wiki seems to have more .9 info than 1.0 info this is what i've gotten of of auth_debug: Oct 11 11:53:37 rsrr1 dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=66.250.131.114 rip=209.73.1.130 resp=xxxxxxxxxxxxxx Oct 11 11:53:37 rsrr1 dovecot: auth(default): sql(test(a)mydomain.com, 209.73.1.130): query: SELECT local_part || '@' || domain as user, password FROM accounts WHERE local_part = 'test' AND domain = 'mydomain.com' AND active = 'Y' ; Oct 11 11:53:37 rsrr1 dovecot: auth(default): client out: OK 1 user=test@ mydomain.com Oct 11 11:53:37 rsrr1 dovecot: auth(default): master in: REQUEST 26 93326 1 Oct 11 11:53:37 rsrr1 dovecot: auth(default): passdb(test@ mydomain.com,209.73.1.130): passdb didn't return userdb entries Oct 11 11:53:37 rsrr1 dovecot: auth(default): userdb(test@ mydomain.com,209.73.1.130): user not found from userdb Oct 11 11:53:37 rsrr1 dovecot: auth(default): master out: NOTFOUND 26 Oct 11 11:53:37 rsrr1 dovecot: imap-login: Internal login failure: user=<test@ mydomain.com>, method=PLAIN, rip=209.73.1.130, lip=66.250.131.114, TLS

[Dovecot] Cannot see new messages in Inbox
by Mark Farmer 16 Oct '05

16 Oct '05

Hi, just wondering if anyone has any suggestions on this. I'm having a rather odd problem in that I cannot see new emails in my IMAP inbox, this is true for both Thunderbird & Squirrelmail. I know the mails are arriving & being delivered correctly as I see the logs for postfix & procmail, and I can also list them from a command prompt on the Linux mail server. The really odd thing is that I can see new mail in other folders within the same mailbox (maildir) without issue, it's only the inbox that seems to be exhibiting the problem. Nothing has changed on the server and all permissions look fine. The only thing I can think of is that I reinstalled my other machine with Linux the other day & setup Thunderbird as normal - I didn't have any problem at the time but yesterday I noticed the problem. I have tried stopping & restarting the dovecot service a few times but this hasn't helped. I've had this running for months now & this just seems to have cropped up, very strange. Any thoughts anyone? farmorg

[Dovecot] How to set up a passwd file for virtual hosting
by Richard Freeman 16 Oct '05

16 Oct '05

Hi, Exim4 is running fine and I am trying to set up Dovecot 0.99 to handle virtual users (http://wiki.dovecot.org/moin.cgi/VirtualhostingWithExim) so I don't have to set up user accounts for each e-mail address I want to server out via pop3. I need to create a user and passd file, a bit like /etc/passwd, but in a different location for my dovecot virtual users. I can create a blank file such as /etc/dovecot/users (beware my increasing vi skills...) but how do I add users and passwords to this? Can I just type them in and separate them with colons? If so, how would I add a password to the file? I am happy using the passwd command which alters my user passwords in /etc/passwd. Can I use it or something similar to create the passwords for the users in my new file /etc/dovecot/users ? Is there any way I can use an MD5 hash or CRYPT format for the passwords? Yours, Richard

[Dovecot] FreeBSD Ports Issues
by Barry Jeung 16 Oct '05

16 Oct '05

Installed dovecot for the first time, using the FreeBSD port. Found 2 issues with the port, and I've only been able to resolve one of them. First of all, the port, (or perhaps dovecot) does work with mysql 4.1 encryption. I had to create a user with access to the mysql table, then do 'set password = old_password('password');' in order to get dovecot to talk to the server. The second issue, is that dovecot seems to be ignoring my user_query settings. I have the following in dovecot-sql.conf: password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 125 as uid, 125 as gid FROM mailbox WHERE username = '%u' The password query works, however the user query seems to default to something else, and no matter how I change the user_query line in dovecot-sql.conf, it uses the same query. Here's an excerpt from my logs: dovecot: Oct 11 03:19:30 Info: Dovecot v1.0.alpha3 starting up dovecot: Oct 11 03:19:31 Info: auth-worker(default): mysql: Connected to (null) (postfix) dovecot: Oct 11 03:19:35 Info: auth-worker(default): sql(user(a)example.com,1.2.3.4): query: SELECT password FROM mailbox WHERE username = 'user(a)example.com' dovecot: Oct 11 03:19:35 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=5.6.7.8 rip=1.2.3.4 resp=AGJqZXVuZ0Bjb2JhbHQtaXQuY29tAHRlc3Q= dovecot: Oct 11 03:19:35 Info: auth(default): client out: OK 1 user=user(a)example.com dovecot: Oct 11 03:19:35 Info: auth(default): master in: REQUEST 1 13590 1 dovecot: Oct 11 03:19:35 Info: auth-worker(default): sql(user(a)example.com,1.2.3.4): SELECT home, uid, gid FROM users WHERE userid = 'user(a)example.com' dovecot: Oct 11 03:19:35 Error: auth-worker(default): sql(user(a)example.com,1.2.3.4): User query failed: Table 'postfix.users' doesn't exist dovecot: Oct 11 03:19:35 Info: imap-login: Internal login failure: user=<user(a)example.com>, method=PLAIN, rip=67.188.145.230, lip=209.25.157.150, TLS So obviously the query fails because that table doesn't exist. However that's not the query that I have in the configuration file. As a matter of fact, I have no idea where it's pulling that query from. Any pointers would be greatly appreciated.

[Dovecot] Dovecot on FC3 with Active Directory authentication
by Jeff Ramsey 16 Oct '05

16 Oct '05

I am building an IMAP server that uses Dovecot/Sendmail on FC3 to replace our POP server that uses Dovecot (via POP)/Sendmail on FC2. My new server is authenticating users via winbind/smb against my WIndows 2003 Active Directory. The authentication is working great. The problem come up when a user gets an email and has not ever logged into the IMAP server via SSH, local, or GDM, therefore that user has no home directory. /etc/pam.d/ssh, /etc/pam.d/login, and /etc/pam.d/gdm all have a line calling mkhomedir.so, which is using the /etc/skel home directory skeleton to create the user's home dir upon successful login, however, when I add that line to /etc/pam.d/dovecot, I get a permission denied error in /var/log/maillog. I'm assuming this is because dovecot is running as the user at this point, and therefore does not have the necessary permissions to create a folder under / home/DOMAIN/, which is where the home dir is supposed to be. If I manually create the folder, and set it's permissions, or if the user logs in via any of the before-mentioned methods, dovecot and sendmail work great. Does anyone else run a similar setup? If so, how did you overcome this problem? If not, can some Linux gurus recommend either altering the write permissions on the /home/DOMAIN directory, or should I try to call the mkhomdir app earlier in the process somehow? Any help would be appreciated. I'm trying to make this as seamless as possible. Basically, I can manually create all the home dirs well enough, but when I add a new user to the Active Directory, it would be nice if this part was automated as much as possible. Thanks, Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Mapping username only for auth
by Andy Cravens 16 Oct '05

16 Oct '05

I am running Dovecot alpha 3 with authentication from the local shadow file. I'd like to change the authentication to use our radius server. I can probably do this through pam. The usernames on the mail server are set up as first initial + last name ( jdoe for John Doe ). The usernames on the radius server are the employee number. Is there a way to map the username to the employee number in dovecot before handing off the authentication to the radius server? I want the usernames on the mail server to remain first initial + last name. I don't mind maintaining a mapping file to go from username to employee number because I can automate this task. Has anybody done this?

[Dovecot] saslauthd/dovecot/root
by Andrew Instone-Cowie 16 Oct '05

16 Oct '05

Hi, I am using SMTP-AUTH over TLS with sendmail, to allow remote users to authenticate and send mail via my server, and this uses saslauthd to authenticate users. I have set up saslauthd with the "MECH=rimap" mechanism, so it uses the local IMAP server, Dovecot, for authentication. I want to do this because Dovecot is set up to use /etc/passwd for user credentials (so I don't have multiple password files to manage), and Dovecot handles restricting the range of valid UIDs (including blocking root). (Using the default MECH=shadow with saslauthd allows all users to authenticate, which I don't want) For real "normal" users, this all works fine - right password = user can relay mail, wrong password = relaying denied. So far so good. If I try to authenticate as root (which I want NEVER to work), with the wrong password, Dovecot correctly refuses to allow root IMAP access and saslauthd/sendmail denies the relay. But if I try to authenticate as root with the correct password (which I still want NOT to work!), Dovecot still refuses IMAP access, and puts this in the maillog: Oct 5 14:16:18 hadrian dovecot: Logins with UID 0 not permitted (user root) Oct 5 14:16:18 hadrian imap-login: Internal login failure: root [127.0.0.1] But saslauthd seems to treat this as a successful authentication and still allows root to relay email! So: Dovecot problem or saslauthd problem? Server is running CentOS 4.1, fully patched. Packages are dovecot-0.99.11-2.EL4.1, cyrus-sasl-2.1.19-5.EL4, sendmail-8.13.1-2. Thanks Andrew

[Dovecot] Confused
by Matt Juszczak 16 Oct '05

16 Oct '05

Hi all, I really don't know where to go from here. I've traced and pasted, but never heard responses.... I'm getting the following (see bottom of this email) in a single day of dmesg....most of the time the error message in the log file is something like: Oct 5 09:21:43 mail1 dovecot: imap(*****): file mbox-save.c: line 280 (mbox_save_init_file): assertion failed: (mbox->mbox_lock_type != F_RDLCK) Some of them also have something to do with storage space. Any ideas at all?

[Dovecot] Dovecot error: Unknown protocol 'imap\
by Paul E Virgo 16 Oct '05

16 Oct '05

First, thanks to Timo for the patch -- fixed missing protocol name error on my Solaris box. Now, I've moved the whole distro, part and parcel, to a Centos 4.0 Linux box, with the HOPE of getting it working there. But when I've set all of it up, I get the error message, mentioned in the 'Subject' line, in my /var/log/dovecot file. Any clues? PEV

[Dovecot] Dovecot pop3 locking up
by Neil Wilson 16 Oct '05

16 Oct '05

Hi guys and girls, I am having a problem with Dovecot. It seems like it's the dovecot auth daemon that is locking up(I'm guessing) I am running SuSe 9.3 Pro, and Dovecot 0.99.14 Everything works perfectly for a few days, and then eventually I end up with tons of what look to be "stale" processes.(I'm guessing roughly 300 like below.) 4204 ? S 0:00 dovecot-auth 24722 ? S 0:00 pop3-login 24723 ? S 0:00 pop3-login 24724 ? S 0:00 dovecot-auth 24921 ? S 0:00 dovecot-auth When I "telnet 127.0.0.1 110" I get a login, and I can type "User blabla" I get an "OK" then I type in "pass blabla" and then I don't get any response, and I have to kill my session with "Ctrl ]" and then "quit". I am using both POP3 and IMAP, but it seems to be only the POP3 daemon that dies. There are roughly 60 users on the network, and it dies after roughly 5 days of usage, and I then have to restart Dovecot by running /etc/init.d/dovecot stop and then start Any help would be appreciated. Thanks. -- Neil Wilson

[Dovecot] deliver: select destination folder
by Dominik Werder 16 Oct '05

16 Oct '05

Hello, I wanted a commandline switch within deliver to select the destination folder within an IMAP account, so I added the -f switch, heres the diff, the implementation is only "proof of concept" hehe, I didnt checked if theres any security riscs in doing this. Could we add something like this to dovecot? diff deliver.c.orig deliver.c 342c342 < const char *destination, *mail; --- > const char *destination, *mail, *folder; 355a356 > folder = NULL; 364a366,373 > } else if (strcmp(argv[i], "-f") == 0) { > /* destination folder */ > i++; > if (i == argc) { > i_fatal_status(EX_USAGE, > "Missing folder argument"); > } > folder = argv[i]; 378a388,391 > if (folder == NULL) { > folder = "INBOX"; > } > 449c462 < if (save_mail(storage, "INBOX", input) < 0) --- > if (save_mail(storage, folder, input) < 0) bye!

[Dovecot] new to dovecot
by John O'Loughlin 15 Oct '05

15 Oct '05

Hello all I'm new to dovecot (and imap in general!) having installed only only today. My current set up is exim as MTA with procmail delivering /var/spool/mail/%user (which gets nfs exported). We also have a pop3 server running as well. I'm moving to new machine and though I'd look at dovecot and squirrelmail. In /etc/dovecot.conf I'm confused by the default_mail_env, what exactly are we trying to set here? We have $MAIL set already, so for example what does the line: default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u try to set Cheers John

[Dovecot] Same email recieved
by Bob Hope 14 Oct '05

14 Oct '05

Some of my users seem to be receiving the same e-mail over and over. This doesn't happen all the time, just once in a while it seems to get stuck in a loop. Is it possible that dovecot is the culprit here or is this a problem with something else? I'm running Postfix/amavisd/dovecot on Slackware 10.1. Regards, Savage

[Dovecot] Message not
by Andrew Hutchings 13 Oct '05

13 Oct '05

Hi, I'm sure this is a bug fixed in CVS or something stupid I did in the config but here goes: I am getting at least one complaint a day about POP login customers getting 'Message not found' errors while getting their mail. The only thing I can find in the messages that could be related is: Oct 12 15:40:18 svr21 dovecot: pop3(user): Mailbox init failed top=0/0, retr=0/ del=0/0, size=0 It doesn't happen on a very high percentage of logins which makes me think its a locking problem of some kind.

[Dovecot] dovecot won't launch
by Chad Cunningham 12 Oct '05

12 Oct '05

Hi, I downloaded the latest dovecot (1.0 alpha 3) and tried numerous installs which get me nothing. No errors, no crashes, no segfaults and no running dovecot. It just seems to silently exit. I was trying to build with mysql support but I've also tried a plain old install, just configure, make install, etc. I get nada. strace doesn't show anything, at least as far as I can tell. No messages are logged. No output to the console. Any ideas? My only guess, no idea if it matters, is that dovecot doesn't like the fact that this is a VPS (User Mode Linux, Fedora Core 3). But I don't see any reason why not, other mail servers are pretty happy... Here's the strace: -bash-3.00# strace dovecot execve("/usr/local/sbin/dovecot", ["dovecot"], [/* 17 vars */]) = 0 uname({sys="Linux", node="monkey", ...}) = 0 set_tid_address(0) = -1 ENOSYS (Function

Hi All, I'm currently doing nightly full backups of /home. I'm not sure if a full back up is the best way to do backups. I know with my fileserver i do weekly full backup and daily incremental which would file on those type of files. I guess my question to the group is, how do you guys backup Maildir? whats the best way of doing it? -- Gabe Granger Pancentric results-driven communications and e-solutions +44 (0) 20 8877 0230 http://www.pancentric.com

Ok, so if anyone runs into a problem where dovecot reports chdir(/home/BLAH) failed with uid NNN: Permission denied in Fedora Core 4 or otherwise, it seems to be a SELinux problem. Turn OFF SELinux and the problem goes away.

[Dovecot] time out error and email with attachments
by Roberto Cipollini 09 Oct '05

09 Oct '05

I'm facing some problem with emails and attachments. I'm not sure it's dealing with MTU (it is set to the maximum number before a fragmentation occurs). I have no errors from pop3, but the following message is the best I can show you just to understand my problem. The log shows this: "imap(roberto.cipollini(a)allmediasolution.com): Oct 04 17:35:03 Error: Timeout while waiting for release of exclusive fcntl() lock for index file /mail/allmediasolution.com/roberto.cipollini/.INBOX/.imap.index " I think that the pop3 process is locking the index file (thunderbird was waiting to download the file) and the imap (i tried to get the file from webmail) is going time out. Can anyone tell me how to fix the time out? any suggestion? do you need more information/logs? can I try different setting in dovecot conf? thanks for any kind of help. Roberto

[Dovecot] chdir failed: Permission denied
by Joe Sislow 09 Oct '05

09 Oct '05

Hi there, Upgrading to Fedora Core 4 from an old server running Red Hat 7.3. I'm moving accounts over by hand, and I'm having the following error crop up for *everyone*. chdir(/home/BLAH) failed with uid 500: Permission denied Now, that UID is correct, the user has that access, and there are no permissions problems changing to that directory. I've got the mail in /var/mail/XXX for each user as a simple mbox. I was browsing through the code to check for what *exactly* dovecot is doing when it's trying to change directory there. The error reporting is a bit spotty. It could be that it can't change to that directory (unlikely). It could be that something in that path is a problem (also unlikely, as the /home directory is world readable and executable), or, it could have something to do with a file or directory it's trying to create. I'm not sure. Could someone let me in on what files or directories that dovecot tries to create by default? This permission denied error doesn't make any sense (I created a brand new user with nothing there, made all of his directories readable/writeable, and executable by EVERYONE, and it STILL gives me this error.

[Dovecot] Dovecot Setup as just a local IMAP server.
by David Terei 06 Oct '05

06 Oct '05

Hey All, Id just like to start by thanking Timo Sirainen and any others that helped produce such a great IMAP server, it was a breeze to set up with no previous experience in mail servers. What I am trying to do is setup a spare computer to run Dovecot and that It stores all my email from my accounts which are all accessed through POP. This way instead of being tied to one mail client (and hence OS and Computer) I just set up my mail client to access Dovecot and then I'm done. So I am trying to set up an IMAP server to store my emails instead of just storing them on my local hard disk really. Now so far Ive set up Dovecot and Its working fine, but How would I get my email accounts mail to be placed in the Inbox of my IMAP account? I'm think I would need to use either fetchmail or getmail to grab my mail. After that do these programs just save it in the appropriate IMAP folder on disk (which would be new?) or do I need a MTA such as qmail setup and fetchmail or getmail passes the email to the MTA which just transfers it locally on the same computer? So any help would be greatly appreciated as well as advice on which software to use, the getmail site attacks fetchmail quite strongly, but I'm not sure of its performance being written in Python as I'm running on an old Pentium MMX(100MHz) using OpenBSD 3.7. Sorry for the long email I never can seem to keep them short :) Cheers, David Terei

[Dovecot] extra characters after mailbox names
by Paul 06 Oct '05

06 Oct '05

After installing alpha3, when I view a list of my IMAP mailboxes in Pine 4.64 on Linux, several of the mailbox names are followed by odd characters: ., ~, and _. So the list of mailboxes looks like: INBOX saved_ sent-mail~ Biz Service. Home_ and so forth. The distribution of the characters remains the same throughout the Pine session, but is different every time I restart Pine. It doesn't happen in Pine 4.63 or any other client, but I associate it with Dovecot rather than Pine because it started exactly when I upgraded Dovecot today, rather than five days ago when I upgraded Pine.

[Dovecot] I need to enable percent hack in dovecot logins
by Eero Volotinen 05 Oct '05

05 Oct '05

I am using dovecot with vpopmail and qmail and problems is percent hack that works with qmail-pop3d does not work with dovecot. So login works like that: firstname.lastname%domain.ext I need that function to work with dovecot too, and I am using stable 0.99.x series of dovecot. Problem is that some Apple machines client can't use at-symbol in their login names. So, where I need to hack sources to convert % -> @ to get login working. By default percent-hack does not work with dovecot. Any help? Thanks. -- Eero

[Dovecot] Changing pop3_uidl_format
by Jeff Simmons 05 Oct '05

05 Oct '05

I recently set up an OpenBSD - Dovecot mail server for a client. Naturally (according to Murphy's Law) they want to use Outlook 2003, pop3s, and leave messages on the server. And just as naturally, the UIDLs don't seem to be working, and when they download mail, they get EVERY email stored on the server, not just the new ones. Other than switching them over to IMAP, I found the following in the Wiki documentation: #POP3 UIDL format to use. You can use following variables: # %v - Mailbox UIDVALIDITY # %u - Mail UID # %m - MD5 sum of the mailbox headers in hex (mbox only) # %f - filename (maildir only) #If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier version 0 : %f # Courier version 1 : %u # Courier version 2 : %v-%u # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u #Note that Outlook 2003 seems to have problems with %v.%u format which is #Dovecot's default, so if you're building a new server it would be a good #idea to change this. %08Xu%08Xv should be pretty fail-safe. pop3_uidl_format = %v.%u So my question is, what happens if I just change pop3_uidl_format to %08Xu%08Xv and restart the server? Will it just change things over to the way I want them, or will it blow up all the existing mail already being stored there? Inquiring minds want to know. Thanks for any help you can provide. -- Jeff Simmons jsimmons(a)goblin.punk.net Simmons Consulting - Network Engineering, Administration, Security "It was on fire when I got here."

[Dovecot] using local-part delimiters in LDA delivery?
by OpenMacNews 03 Oct '05

03 Oct '05

hi all, i've exim 4.53RC2 + dovecot-cvs on OSX 10.4.2. i'm working on implementing recipient-delimiters for delivery from exim to a user's imap store using dovecot's cvs-lda. reading on the wiki (Jakob's latest comments?): " ... the part after the delimiter is passed to the lda as an additional parameter. so dovecot-lda should handle that parameter and leave the separator handling to the MTA. The MTA has to handle it anyway." it looks likes it's possible ... with appropriate changes in exim to my router: dovecot_localuser: driver = accept domains = +local_domains local_part_suffix = +* local_part_suffix_optional transport = dovecot_lda and transport: dovecot_lda: driver = pipe command = /.../deliver \ -c /.../dovecot-deliver.conf \ -d $local_part@$domain message_prefix = "" message_suffix = "" delivery_date_add envelope_to_add return_path_add log_output user = MY_MAIL_USER i'd like to be able to build delivery conditions in dovecot so that, e.g. mail to: bob(a)mydomain.com is delivered to "bob"'s default INBOX. but, mail to: bob+spam(a)mydomain.com is delivered to any specified (either a server-wide common relative path, or a user-specified) SUBFOLDER, say "bob/INBOX/.../.../spam_to_look_at" defined by a dovecot-rule invoked by the delimiter "spam" ... this is a little different than the approach Mark mentioned of delivering directly to folder_name specified by the local-part-after-delimiter ... questions: (1) until the two conf files merge, i'm guessing there needs to be some conditional logic in dovecot-deliver.conf rather than in dovecot.conf. correct? or should i be thinking SIEVE rules? (2) exactly WHAT "additional part" do i grab in dovecot? thx! richard

[Dovecot] Using procmail with virtual users...
by Arnaud Guiton 01 Oct '05

01 Oct '05

Hello all, I've a working dovecot installation on my machine, using exim3, virtual users and maildirs. I would like to add procmailrc rules for these (virtual) users, but i've not succeeded with that. The authentication is done with a passwd-file looking like this : testuser:password:uid:gid::/home/mail/testuser::chroot:maildir:/home/mail/testuser/Maildir/ i've put .procmailrc files in /home/mail/testuser/.procmailrc, but it this not taken into account, because the MTA never calls the procmail router as it resides after the dovecot one. How is the proper way of using procmail with virtual user (and is it at least possible) ? Thanks, -- Arnaud

[Dovecot] Red Hat ES 4 - dovecot-auth: Unknown password scheme SMD5
by mel llaguno 01 Oct '05

01 Oct '05

I have a couple of questions regarding the default dovecot packaged with RedHat ES 4. The dovecot version is 0.99.11-2.EL4.1 which I assume is considerably behind the current stable version of 0.99.14. Is it the fact that I am using an older version of dovecot that SSHA passwords in an openldap directory are not recognized and give the following error: dovecot-auth: Unknown password scheme SMD5 ? LDAP is working as expected for NFS maildirs. I have dovecot 0.99.13 working on fedora core 3, but the stability of fedora leaves much to be desired and would like to get a stable, low maintenance install of dovecot on an enterprise supported linux. Redhat does not have packages for 0.99.14 and I would rather compile from source if possible. I've specified --with-ldap as part of the configure script, but am wondering if there is anything more to add to support SSHA passwords. Until dovecot 1.0 is proven in the field, it is not a consideration for the production environment this server is being used for. Any help with this matter would be greatly appreciated. TIA, Mel Llaguno

[Dovecot] Can't connect to auth server at default: Connection refused
by Chris Wakelin 30 Sep '05

30 Sep '05

We've being running with Dovecot 1.0-stable since Tuesday, and on the whole it's gone very well (meaning nobody's noticed!). My best estimate is we're using half the disk accesses and 2/3 the CPU of UW-IMAP/Qpopper. We've quite a mixture of error messages in the logs, the most worrying of which is that several times we've had a few seconds of "xxx-login: Can't connect to auth server at default: Connection refused" (where xxx is pop or imap). It seems to sort itself out shortly afterwards. We're using userdb=passwd, passdb=passwd (authenticating via NIS). From Tuesday we'll be using passdb=pam (pam_ldap to Active Directory). My first guess is that some dovecot-auth process stops responding and gets killed off. Is this right? Other errors we're seeing include 1) pread_full() failed with mbox file /export/mail/c/37/sau04djp/INBOX: No such file or directory (when there is!) 2) mbox sync: UID inserted in the middle of mailbox (especially with .prayer folders - configuration folders for our Webmail) 3) file mbox-lock.c: line 505 (mbox_lock): assertion failed: (lock_type == F_RDLCK || ibox->mbox_lock_type != F_RDLCK) presumably some of these are fixed in alpha2.

[Dovecot] redirect and sieve BUG
by List Subscriptions [Obfusc8.Org] 30 Sep '05

30 Sep '05

I've only just subscribed to the list, but in reading through the back-issues have come across a bug with dovecot-lda that was reported previously, and I can reproduce. Using dovecot-lda CVS with Revision 1.21 of deliver.c (as newer versions won't compile against 1.0-alpha3), with dovecot 1.0-alpha3 and postfix 2.1.5 Rredirects mangle some headers - the 'To:' header ends up as: To: undisclosed-recipients: ; And there is no subject header. Running sendmail from the cmdline with: sendmail -i -f '<>' -- destination at address.com <msgtext> as suggested to test by *Timo Sirainen *results in a correctly formatted message. The mail_send_forward function in mail-send.c looks sane from what I can see, but then I'm not a C coder... Any clues guys? Cheers, Pete

[Dovecot] Maildir and counting inodes
by Andy Cravens 30 Sep '05

30 Sep '05

I've been testing with alpha 3 and I am about ready to go production. I am switching from mbox to maildir and I'd like to know if there is a formula or rule of thumb for determining if your file system will have enough inodes to handle all the mail message files. I could write a script to look at each user's mbox files, count the number messages and calculate the average number of emails per user, then add a fudge factor for expected growth. However, I doubt anybody actually goes to this much trouble to plan ahead. Or do they? I'm running Solaris 9 and when I created the file system I just used the defaults. If I need to change anything, I'd rather do it before going production. Thanks for any info you can provide on this subject.

[Dovecot] ManageSIEVE services with Dovecot cvs-LDA?

hi all, has anyone had any success in getting the current dovecot cvs-lda's implementation of CyrusSIEVE responding to a ManageSIEVE client? in particular, i'm hoping that one can use, e.g., Mulberry's Client- & Server-side sieve editor: <http://www.cyrusoft.com/sieve/sievescreens.html> if i telnet to my dovecot box's sieve port ( = 2000) i get no response at all ... telnet localhost 2000 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host net-stat shows nothing on port 2000, and, afaik, there's no mention of a server on the wiki ... so i'm either doing something wrong, or "it" is simply not there. has a sieve server been implemented? any plans? thx! richard

But I found that I must add the mail=mbox:/var/spool/virtual/%d/%n part. Without this part, the dovecot seems not checking the right location of mail spool and simply say that "no new email". Now I added this part together with "home=/tmp" part into userdb config and It works now with IMAP folder in /tmp directory. But I want to ask if there is any file locking problem as I am running virtual email with vmail as owner for all mbox accounts. And it seems that they are all share the same IMAP folder located in /tmp directory.

[Dovecot] Hostname passed to PAM as rhost
by Tom Alsberg 27 Sep '05

27 Sep '05

(I am sorry to bother the list with something I should have verified myself right now - I simply do not have access to the source code here) Thinking of some limit I wanted to put with authentication, I am wondering - when Dovecot authenticates a user using PAM, now that (in 1.0) it passes the rhost item to PAM, it passes a hostname, not an IP address. Does it double-verify the DNS record before it trusts this to be the hostname (first checking the IP address in in_addr.arpa and then checking that the hostname indeed maps back to the same IP address)? That is necessary in order to trust the client address when determining authentication strength in the PAM module based on the client location (specifically we want stronger authentication when the client comes outside of our network, while inside a plain password suffices), as else anybody could "spoof" the hostname by changing the IN PTR record of his IP address to point back to some "trusted" hostname (given he has control of the DNS zone his host is in, which is completely possible given the server knows nothing about it).

[Dovecot] POP3 problem
by michal 27 Sep '05

27 Sep '05

Hey all this is my first post to this list. I have fresh Red Hat AS 4.0 with postfix 2.1. This will be my mail server. I have one problem with pop3. My mail server is working properly. I did the following test: Sent an email to some other server(yahoo.com)->email got there fine. >From that other server(yahoo.com) replaied-> to the new server and email got there fine,checked using pine. Now in x windows on the mail server if i lunch email client software and set up the account, then i can send and receive emails fine so pop3 is working. But when i go to different machine like PC set up outlook then i cannot receive emails. I get error in outlook that the connection has failed. So i telnet 192.168.1.10 110 and I have gotten response from the server 250 dovecot OK. I really dont what to do at this time. I have been trying couple different things without any luck..... need some help? Mike

[Dovecot] How safe is mbox_very_dirty_syncs?
by Chris Wakelin 27 Sep '05

27 Sep '05

I've tried turning on mbox_very_dirty_syncs for myself (and a few other brave souls running 1.0-alpha3 rather than 1.0-stable) again to see what perfomance gain it gives (see thread http://www.dovecot.org/list/dovecot/2005-July/007956.html) Now we aren't running UW-IMAP at all, how safe is mbox_very_dirty_syncs assuming the only other process writing to mailboxes is our MTA (exim) which simply appends messages to the end? Is it safer still using Dovecot 1.0-alphas and the LDA? Does it matter if there are concurrent connections to the mailbox?

[Dovecot] new mailbox format v2
by Timo Sirainen 27 Sep '05

27 Sep '05

Updated version. The previous one was a bit too complicated with flag updates for pretty minimal benefits. Changes: - writing/reading mail flags can be disabled to get better performance without it requiring any changes to how the files are normally handled (so mixed more works fine). - writing flags now requires getting shared locks. so there's the overhead of locking but flag writers don't have to wait for each others. - reading requires no locking anymore. the comment in the previous version about reading only half a mail being a problem doesn't actually matter, since if a client tries to read an expunged mail Dovecot already disconnects the client immediately (since most clients can't handle such situation well anyway). - no more problems with mailbox readers locking out expungers - note about fcntl() locking being able to provide even higher concurrency - works just fine with plain dotlocks, so works fine with NFS And looks like I forgot to explain the "mail header padding" before. I'm not exactly sure if it's useful or not, but it doesn't hurt to have it there if it's wanted. The idea was anyway that if you're writing more than one flag at a time, having a 512 byte padding would make sure that when writing the few bytes the OS will only have to read one sector from disk (512 bytes in all todays OSes I believe?) to get the non-written parts of the sector instead of possibly reading two sectors. So it might help with trading disk reads for some wasted disk space. Generic ------- The point is to have a mailbox format where the mailbox can consist of one or more files. Grouping multiple files in a single file makes it faster to read, but it's slower to expunge mails from the beginning of the file. So this format would allow sysadmin to specify rules on how large the files would be allowed to grow. Index File ---------- Named "index". Index file gives a mapping between UIDs <-> filenames: Header: <uidvalidity> <last-used-uid> Record: <uid-first> <uid-last> <filename> Record: .. eg.: 1127468129 5 1 3 msg.1 4 4 msg.4 All of the UIDs don't have to actually exist in the file if they have been expunged. The record should be removed once all of the UIDs have been removed from it (and the file itself been deleted). The same file may appear multiple times in the index. For example: 1 2 msg.1 3 3 msg.3 4 5 msg.1 This means that UIDs 1, 2, 4 and 5 are in file msg.1, but UID 3 is in file msg.3. The filename doesn't matter as long as it's unique, but probably wouldn't hurt to include its first UID in the filename so humans can find mails more easily. The filename however must not end with ".lock". The file is modified by creating first exclusively owned "index.lock" file, updating it and then rename()ing it over the index file. This lock file shouldn't be held for a long time, so if it exists, and it doesn't get modified at all within 30 seconds, it can be overwritten. Before rename()ing over the index file, you should check with stat() that the index.lock file is still the same as you expect it to be (in case your process was temporarily stopped for over 30 secs). The index file's mtime timestamp must grow after each modification. This makes it easy to check if new mail has been added to the mailbox. Mail File --------- File header: Bytes Format Description 8 hex Header size 16 hex Append offset 4 hex Mail header size 4 hex Mail header padding 4 hex Keyword count in mail headers Mail header: Bytes Format Description 8 hex UID 16 hex Mail size 1 1/0 Answered flag 1 1/0 Flagged flag 1 1/0 Deleted flag 1 1/0 Seen flag 1 1/0 Draft flag 1 1/0 Expunged flag n 1/0 Keywords The file layout then goes: <File header> - possible padding due to Header size <Mail header #1> - possible padding due to Mail header size <Mail data #1> - possible padding due to Mail header padding (ie. next Mail header's offset is divisible with Mail header padding) <Mail header #2> etc.. The UIDs must be ascending within the file (but as said above, some UIDs between them may exist in other files). If mail has been marked with expunged-flag, it should be treated as if it was already expunged. The mail will really be expunged later in some nightly run. Reading the files requires no locking. If while reading you happen to hit unexpected end of file, it means that mails were expunged from the file. After that you'll look at the index file again to see which file the mail went and continue from there on. If the mail isn't found, it means it got expunged. Expunging happens by locking the file and then copying all non-expunged mails after the first expunged one to new file. Then update the index file with the new location for the UIDs, and at last ftruncate() at the position of first expunged mail in the original file. Flag updates require locking the file as well, otherwise we might try to write past the end of file when another process is expunging the mails. Shared locking can be used for flag update locking since each flag update can be atomically changed by writing one byte. Appending mails can be done by either locking existing file and appending to it, or creating a new file. If appending to a new file, create it with .lock suffix and then check that the file without .lock wasn't already just created to prevent race conditions. When appending to existing file, check "Append offset" from file's header. If that offset is at the end of file, just append there. Otherwise read the mail's header from there. If it has a non-zero UID and index file says that the same UID exists in this file, jump over the mail and do the same checks for all the rest of the mails in the file. Once the check doesn't match or you reach EOF, update the append offset in the header to that offset and write your mail there. Initially write the UID in mail's header as zeroes ('0', not NUL). Once the append is completely finished, you'll have to update it with the new UID. You'll do this by locking index file, reading the latest last-used-uid and using the next value for your UID. Once you've written it, rewrite the index file with updated last-used-uid field and your UID added to it. After this, update the append offset in the mail file and unlock it. If fcntl() locking is used, locking only specific ranges can give more concurrency. Flag updates only need to lock the part of the file they're modifying. Expunges need to lock the part which it's removing. Appending needs to lock from <end of file-1> to end of file (ie. l_len=0). Keywords file ------------- Named "index.keywords". This contains mappings between keyword numbers and names. TODO: write how it's updated Recent file ----------- "index.recent.<uid>" file tells what the last non-recent UID was. The file doesn't have any data inside it. When opening the mailbox you should find and rename() the existing index.recent.<uid> file to the new index.recent.<last-uid>. A successful rename() means the mails between <uid>+1 .. <last-uid> are recent for you. A failed rename() means that someone else managed to do it. You should look for the file again and if it was renamed to less than <last-uid>, you should try again. Nightly cleanups ---------------- Because expunged mails may be left lying around for a while, there probably should be some nightly check that cleans them up. Other cleanups that may be necessary after crashes are: - .lock files - expunged data at the end of files (can be checked with same rules as how appending determines the offset where to append) Alternative ways to use ----------------------- Expunging mails isn't very filesystem quota friendly since it requires creating another file to copy the expunged mails to. This could also be done by just moving the data within the file. This however requires that all file reads must also be shared-locked. Also it has the problem of leaving the mailbox corrupted if the copying gets aborted in the middle. For the best performance the mail flags could be stored only in Dovecot's index files. In that case the flag update locking isn't slowing down expunges (and if fcntl() locks can't be used, doesn't slow down appends either). Also there's no need for keywords/recent files. Compatibility ------------- If needed, it would be possible to create new/ and tmp/ directories under the mailbox to allow mail deliveries to be in maildir format. The maildir files would be then either just moved or maybe be appended to existing mail files.

[Dovecot] Mail directory funkiness
by Ted Kaczmarek 27 Sep '05

27 Sep '05

I am using dovecot-0.99.14-4.fc4 on FC4, was testing using mbox and than switched to using Maildir. default_mail_env = maildir:~/Maildir >From evolution when I create a folder the folder is created in ~/mail instead of ~/Maildir I am still rather new to dovecot, but this does not make sense. I made sure to restart dovecot, even added a .procmailrc. cat .procmailrc MAILDIR=/home/tedkaz/Maildir :0 ./ I am going to grab the latest version and test with that, but if if anyone has insight into how I got here it would be appreciated :-) Likely a pilot error.

Timo. I have installed Dovecot 1.0 alpha3 and tested. It is a mbox POP3 only server.

Why I need a IMAP folder in a POP3 only server and can I change that folder to /tmp directory.

[Dovecot] Misbehavior with Dovecot and Mulberry
by Jon Roma 27 Sep '05

27 Sep '05

I'm having a bit of misbehavior wherein Dovecot seems to refuse to cooperate with my Mulberry MUA. By and large, everything works great. I can move mail back and forth happily. I can compose a note and copy the outgoing mail to my Dovecot "Sent" folder using my default Mulberry settings. But if I reply or forward a mail, I get a Mulberry error popup saying that it "couldn't decode the response from the server" and that the operation was unsuccessful. This was somewhat mystifying (especially since this does work for a newly composed message as opposed to a reply/forward), so I turned on Mulberry logging. This is what I see (with unrelated operations clipped from the log). First, the first case where I create a new message, send it, and save a copy in my Sent folder: --> #6.3408 Mon Sep 5 23:24:27 2005 A00085 APPEND Sent (\Seen) {418+} * 5544 EXISTS * 1 RECENT A00085 OK Append completed. All's well there. Mulberry does a FETCH to grab the new message (reply) from my Sent folder and then does a SORT so that it can order it properly in the display. This too succeeds but is probably irrelevant to us. After a couple NOOP commands come and go in the background, I try to reply to a message in one of my mailboxes. In this case it happens to be the one in my Sent folder. So Mulberry issues a FETCH (you can see the original mail there in the FETCH response from Dovecot). It then does a STORE of the original mail, apparently to update the \Answered flag. It then tries to APPEND the reply to the Sent folder, but this time, the server comes back with a NO. See below --> #6.3408 Mon Sep 5 23:24:43 2005 A00089 FETCH 5544 (BODY[1]) * 5544 FETCH (BODY[1] {63} ) A00089 OK Fetch completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00090 FETCH 5544 (RFC822.HEADER) * 5544 FETCH (RFC822.HEADER {355} Date: Mon, 05 Sep 2005 23:24:27 -0500 From: Jon Roma <roma(a)uiuc.edu> To: Jon R Roma <roma(a)uiuc.edu> Subject: Test 1 Message-ID: <DDDD999F0F4E38F8C1510CC8(a)jrr2.isdn.uiuc.edu> X-Mailer: Mulberry/3.1.6 (Win32) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline ) A00090 OK Fetch completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00091 STORE 5544 +FLAGS (\Answered) * 5544 FETCH (FLAGS (\Answered \Seen \Recent)) A00091 OK Store completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00092 APPEND Sent (\Seen) {610+} A00092 NO I am having similar problem saving a draft to my Drafts folder and suspect the same thing is behind both of these. I didn't create a Mulberry trace log for this but can do so if need be. I am running 1.0-test80 with Timo's patch to fix the "time off by 200 minutes" error with mbox. All my folders are maildir at this point -- I've converted them out of my UW mbx format store. My client is Mulberry 3.1.6 for Windows and the OS is AIX 5.1. This weird behavior is a mystery to me!

[Dovecot] 1.0alpha3 packages for debian
by Jaldhar H. Vyas 26 Sep '05

26 Sep '05

Sorry this took even longer than I thought but they should be arriving in unstable this afternoon. I also have a backport for stable available at http://www.braincells.com/backports This directory is not aptable so manually install the packages for now. (Hopefully backports.org will have their sarge repository open soon. When that happens they will move there.) The configuration file format has changed so you will want to carefully check /etc/dovecot/dovecot.conf when upgrading. I forgot to put a note about that in NEWS.debian sorry. I think I might have forgotten a couple of config file tweaks people have suggested and in general, if you sent me mail in the past month or so and I didn't respond or the problem still isn't fixed, please give me a nudge. This is why you really ought to use the Debian bug tracking system rather than mailing the maintainer. Anyway, enjoy. -- Jaldhar H.

[Dovecot] virtual domain
by Barry Kwok 26 Sep '05

26 Sep '05

we are currently using vm-pop3d to implement virtual domains. But due to some locking problem in vm-pop3d, we want to test the possibility to change to dovecot. Currently, in vm-pop3d, the passwd file is located in /etc/virtual/domain1.com/passwd /etc/virtual/domain2.com/passwd and the passwd format is: user: md5 encrpted password and the email is store in /var/spool/virtual/domain1.com/user /var/spool/virtual/domain2.com/user and we login as user(a)domain1.com, user(a)domain2.com . We want to maintain this format as login id and the password format. What should be changed in dovecot.conf? Thanks.

i can't find a trace of any sieve mgmt services in dovecot as yet, and haven't found anything in this list ... so, if i *am* missing it, if someone would be kind enuf to point me in the right direction, i'd appreciate it! 8-} in the meantime, a little more info for those interested ... the latest spec for sieve management, "A Protocol for Remotely Managing Sieve Scripts", can be found at: <http://www.ietf.org/internet-drafts/draft-martin-managesieve-05.txt> iiuc, one of the authors, Tim Martin / Mirapoint Inc., is the "Tim" of "timsieved" -- Cyrus' ManageSIEVE 'server' bundled with cyrus-imap. i can strip timesieved it out of a successful build of cyrus-imap, but it seems to be dependent on cyrus-sasl ... as such, i'm not sure how to integrate it with dovecot's SASL auth methods. i have a feeling that such fuctionality would have to be re-implemented in dovecot alongside of sieve itself ... and probably should, if it were to be included. the courier-imap mailing lists also have folks searching for an alternative to timsieved ... richard
