[Dovecot] quota problem
by claper＠fmed.edu.uy 18 Nov '05

18 Nov '05

Hi, i have a problem with dovecot and quotas, when a user has over-quota he can't access the mail account to download mails and solve the quota problem. I'm using debian sarge (stable) and quota v1 (vfsold), i have installed dovecot in debian way apt-get install dovecot dovecot-common dovecot-pop3d users only can access via pop3 to their mails. This is the error i get when i try to access with an over-quota user pop3-login: Nov 18 12:35:05 Info: Login: prueba [164.73.128.2] pop3(prueba): Nov 18 12:35:05 Error: file_set_size() failed with mbox file /var/mail/prueba: Disk quota exceeded pop3(prueba): Nov 18 12:35:05 Error: mbox file /var/mail/prueba was modified while we had it read-locked, make sure all your software accessing mboxes uses the same locking methods (fcntl, flock, dotlock) pop3(prueba): Nov 18 12:35:05 Error: file_set_size() failed with mbox file /var/mail/prueba: Disk quota exceeded pop3(prueba): Nov 18 12:35:05 Error: Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-11-18 12:35:05] it looks like dovecot wants to write my mbox file and then gets the error with the quota, this is what i think could be helpfull from my config file protocols = pop3 pop3s mail_extra_groups = mail default_mail_env = mbox:%h/mail:INBOX=/var/mail/%u:INDEX=/var/dovecotindex/%u:CONTROL=/var/dovecotindex/control/%u mail_full_filesystem_access = yes mail_save_crlf = yes mbox_locks = dotlock thanks a lot claper ---------------------------------------------------------------- Mensaje enviado desde http://correo.fmed.edu.uy

[Dovecot] Retention Policy Feature(?)
by Ted Strzalkowski 18 Nov '05

18 Nov '05

I am currently using dovecot 0.99.14p1 on OpenBSD 3.8, mbox format, procmail+sendmail MTA. I subscribe to quite a few mailing lists and currently have procmail sorting mail into the proper mboxes. I was hoping there would be some sort of retention policy feature built in to dovecot. I want to delete mail more than X days old from X folders. I have combed the documentation, list archives, and google. Is this a feature? If so, where can I find more information on it. If this isn't a feature, is it in the works or is it left out to keep things "slim line"? Ted Strzalkowski

[Dovecot] Authentication hanging with 1.0alpha4 - mysql issue?
by brock＠theskeptik.com 18 Nov '05

18 Nov '05

Hello, Recently, I configured my server (RHEL4, 2.6.9-22.0.1.ELsmp) to run postfix 2.1.5 and dovecot 1.0 alpha4. It connects to a MySQL database (mysql 4.1.12) to verify authentication. From 30 minutes to an hour after dovecot is started, authentication and mail access works perfectly. However, after those 30 minutes to an hour, further attempts to authenticate with dovecot result in "hangs" - no temporary authentication errors are reported to the client, and no errors are logged to the dovecot log. The dovecot is still running, and responds to connections, but once the password is sent, the server fails to respond. The following line is registered in the log with each authentication attempt after the "hang": > dovecot: Nov 17 22:44:41 Info: auth-worker(default): mysql: Connected to localhost (postfix) along with an eventual disconnection notice (although no Login: line is registered): > dovecot: Nov 17 22:45:41 Info: imap-login: Disconnected: Inactivity: method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Killing and restarting dovecot immediately fixes the problem, although it reappears after 30 minutes to an hour. Following is my dovecot-sql.conf: driver = mysql connect = host=localhost dbname=postfix user=dovecot_read password=**obfuscated** default_pass_scheme = PLAIN-MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT 89 AS uid, 89 AS gid FROM mailbox WHERE username = '%u' (dovecot_read has SELECT access on the postfix database, and 89 is the uid/gid of the owner of the maildirs.) I searched through this list's archives over the last two months and couldn't find anything related to this. Does anyone have any idea what the problem could be? Regards and many thanks in advance.

[Dovecot] Mailbox isn't a valid mbox file
by Cliff Hayes 16 Nov '05

16 Nov '05

Hello all, I have a new installation of Fedora 4 and Dovecot 1.4.Alpha4 A small percentage of my users are getting unable to pop mail from a client (ie: Outlook), they get continually prompted for username/password. The error they get is: Mailbox isn't a valid mbox file. When I look in the file, I don't see anything unusual. There's not much info on the Internet about this problem. The only thing I found mentioned blank lines in the file. So, I tested and found that I'm able to get mail on other accounts regardless of whether there are blank lines in between messages. Thanks, Cliff

[Dovecot] Improper listening on IMAPS
by Marian Hercek 16 Nov '05

16 Nov '05

I want Dovecot handling IMAPS. /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem The problem is that Dovecot is not listening on 993 port, or there's something listening on 993, but it does not introduce itself. There's no problem if Dovecot listens on 143 (IMAP). When I telnet on 143, Dovecot introduces itself like this: $ telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. But when I telnet on 993: $ telnet localhost 993 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. There is not other process that would be listening on IMAPS 993 port. Dovecot was compiled with SSL support: # ldd /usr/sbin/dovecot libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x20597000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x205c6000) libdl.so.2 => /lib/libdl.so.2 (0x206ba000) libc.so.6 => /lib/libc.so.6 (0x206be000) /lib/ld-linux.so.2 (0x20580000)

[Dovecot] Sub-Folder Query
by Kaan Kivilcim 16 Nov '05

16 Nov '05

Hi all, I have a question in regards to folders/sub-folders with dovecot and Microsoft Outlook 2000. When creating folders if you do not append a "/" to the end of the folder name you cannot create sub-folders. Is there any solution/work around so that users do not have to append a slash on the end of the folder name? I would like to use dovecot for about a 50-user IMAP server however adding a slash to the end of folder names won't go down well with the users who are not the most computer literate people.

[Dovecot] Need to move mail
by Brent Clark 15 Nov '05

15 Nov '05

Hi all My imap server is getting to the stange where I need to start worring about the disk usage. Due to the number of users we seem to be hiring, I need to start looking at a new mail server, suppose its a blessing in disguise too. Would it be ok to just tar my current users mail (there home directory, I dont use virtual setup) and the untar it on the new mail server. Is there anything that dovecot on the new machine will complain about. Obviously I would tar everything, indexes etc. Just something I was wondering. Kind Regards Brent Clark

[Dovecot] a proposal to increase the stability
by Udo Rader 15 Nov '05

15 Nov '05

Hi, we've been using dovecot for the past 2 years or so for our 3K+ mail accounts and have never regretted our step. Yet from time to time there appear to be, how shall I say, "major" problems in the daemon that of course are no reason to whine and complain about because dovecot is OSS and everybody can do something about it. And that's where I would like to make a suggestion. From our own software projects I am used to the usage of extensive testing frameworks, like junit for java based applications. I almost completely lack knowledge about C/C++ programming, so I have no idea if something like this could be done for dovecot. For "the other end" of the mail chain I know dumbster, which is a fake SMTP server used for testing MUAs. So maybe something similar could be done for IMAP/POP3 servers? What I am thinking of is to run those tests before anything new is released. On the other hand I cannot even estimate how much work would be needed for this ...

[Dovecot] Leftover mbox behavior from uw transition
by Adam Porter 15 Nov '05

15 Nov '05

Currently running dovecot 0.99.12 on a RHEL 3 server. This system used to use UW imap with mbox mailboxes, is now using dovecot with Maildir. (Actual user shell logins are not permitted.) Performance is tremendously improved. However, we still have users that have their client imap root set to the "mail" or "mail/" directory. (Can't reach/change them all easily.) As a result, people are still (inadvertently) creating/using mbox-style mailboxes (sent mail folders most often) on the dovecot server (dovecot of course handles them without complaining) which grow and hurt server performance. Now that we've figured this out, I think we could use mb2md in a script to convert these big mbox files to Maildir. (Is there a better way?) But what would be the smart way to prevent people from creating these mbox files and still have their client work correctly with their imap root set to "mail"? We currently use: default_mail_env = maildir:~/Maildir Thanks! -Adam

[Dovecot] entourage pop to dovecot imap migration
by wagner 15 Nov '05

15 Nov '05

I'm beginning to migrate my years of mail stuck in Entourage 2004 (MacOSX) to dovecot imap on Fedora FC4. No matter how I have tried I cannot get the status flags to migrate. Eg: all the mail, once transfered from the pop archive to the imap server looses all Status: and X-Status: flags and ends up being marked "new" on the imap side. After lots of testing it appears that, while simply having both pop and imap configured Entourage and dragging messages from the pop config to the imap area does move messages, all flags are lost. This also is the case if I export Entourage folders as mbox files and then import them into the imap server with Entourage or Mail.app. Has anyone else came upon this obstacle? Any advice? I am in the process now of gathering information to facilitate my own "migration utility". It seems the Entourage DB keeps the read/flagged/replied flags for each message in its own internals and doesn't deem it worthwhile to export them as part of it's mbox export nor retain them as Status or X-Status flags when moving messages from its pop DB to the imap server. I believe I can write a script to work on a set of found, for example, "replied to" messages to add an "X-Status: A" to their headers before moving them to the imap server. Same for "read" and "flagged" MS DB internals to Status/X-Status headers. With these headers added, moving them to the imap server, from my limited testing would seem to be the method to keep those status flags per message? Does dovecot use those flags or does it have its own means of storing that status information? Will it at least use those in the messages to populate its DB if it does have its own method? Flags I've identified so far: Status: O - old Status: RO - recent old(?) X-Status: A - replied to X-Status: F - flagged Thanks for any insight or suggestions.

[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?

[Dovecot] dovecot 1.0alpha 4 error
by Alex Campoe 11 Nov '05

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.

by Jaldhar H. Vyas 07 Nov '05

07 Nov '05

I finally got some free time and uploaded 1.0alpha4. It will arrive in the archive by tomorrow afternoon. Together with the most recent libssl0.9.8 upgrade I think this will fix the SSL problems users have been facing. -- Jaldhar H.

[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.

[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

[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. I guess there is something wrong inside dovecot-auth od dovecot process itself. I just start to receive "01 NO Authentication failed." or "-ERR Authentication failed." from dovecot and "Authenticate PLAIN failed: Unsupported authentication mechanism.: method=PLAIN" in my logs, even though I used the same PLAIN two minutes ago without a problem. Here is my dovecot.conf: nevoservice# egrep -v '^[ ]*(\#.*)?$' /usr/local/etc/dovecot.conf protocols = imap pop3 ssl_disable = no ssl_cert_file = /etc/mail/certs/server.crt ssl_key_file = /etc/mail/certs/server.key disable_plaintext_auth = no log_path = /var/log/dovecot/log info_log_path = /var/log/dovecot/info login_user = dovecot login_processes_count = 1 verbose_proctitle = no first_valid_gid = 0 mail_extra_groups = mail mail_debug=yes default_mail_env = mbox:/var/mail/%u maildir_copy_with_hardlinks = yes protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb passwd-file { args = /usr/local/etc/dovecot.passwd } userdb passwd-file { args = /usr/local/etc/dovecot.passwd } user = root } Here are two lines in dovecot.passwd which define the user that I use: wail:password-hash:1050:1032:Administrator wail.spb.ru:/home/wail.spb.ru:::/var/mail/wail wail@nevoservice.ispvds.com:password-hash:1050:1032:Administrator wail.spb.ru:/home/wail.spb.ru:::/var/mail/wail A few lines from my /var/log/dovecot/info file: dovecot: Oct 10 02:03:11 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=82.146.50.34 rip=82.146.63.23 resp=AHdhaWwAVGxNSFRuUlI2 dovecot: Oct 10 02:03:11 Info: auth(default): client out: OK 1 user=wail dovecot: Oct 10 02:03:11 Info: auth(default): master in: REQUEST 3 53919 1 dovecot: Oct 10 02:03:11 Info: auth(default): master out: USER 3 wail uid=1050 gid=1032 home=/home/wail.spb.ru mail=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3(wail): Effective uid=1050, gid=1032 dovecot: Oct 10 02:03:11 Info: pop3(wail): maildir autodetect: stat(/var/mail/wail/cur) failed: Not a directory dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox autodetect: data=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox autodetect: INBOX file: yes (/var/mail/wail) dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox: data=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox: root exists (/home/wail.spb.ru/mail) dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox: root=/home/wail.spb.ru/mail, index=/home/wail.spb.ru/mail, inbox=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3-login: Login: user=<wail>, method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 dovecot: Oct 10 02:03:13 Info: pop3(wail): Logout. top=0/0, retr=0/ del=0/3, size=5372 dovecot: Oct 10 02:03:20 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=82.146.50.34 rip=82.146.63.23 resp=AHdhaWwAVGxNSFRuUlI2 dovecot: Oct 10 02:03:20 Info: auth(default): client out: OK 1 user=wail dovecot: Oct 10 02:03:20 Info: auth(default): master in: REQUEST 4 53918 1 dovecot: Oct 10 02:03:20 Info: auth(default): master out: USER 4 wail uid=1050 gid=1032 home=/home/wail.spb.ru mail=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3(wail): Effective uid=1050, gid=1032 dovecot: Oct 10 02:03:20 Info: pop3(wail): maildir autodetect: stat(/var/mail/wail/cur) failed: Not a directory dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox autodetect: data=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox autodetect: INBOX file: yes (/var/mail/wail) dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox: data=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox: root exists (/home/wail.spb.ru/mail) dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox: root=/home/wail.spb.ru/mail, index=/home/wail.spb.ru/mail, inbox=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3-login: Login: user=<wail>, method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 dovecot: Oct 10 02:03:21 Info: pop3(wail): Logout. top=0/0, retr=0/ del=0/3, size=5372 dovecot: Oct 10 02:03:28 Info: pop3-login: Authenticate PLAIN failed: Unsupported authentication mechanism.: method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 dovecot: Oct 10 02:03:30 Info: pop3-login: Aborted login: method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 We see here two successfull logins with PLAIN and then suddenly PLAIN becomes unsupported.

[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.

If you have been bitten by bug #334180 and dovecot 1.0alpha3-2.0.1 rest assured the problem is being worked on. In the meantime you should downgrade to -2 which can be found at: http://snapshot.debian.net/archive/2005/10/08/debian/pool/main/d/dovecot/ -- Jaldhar H.

[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] Authentication using native MySQL PASSWORD() function
by Tom Sommer 28 Oct '05

28 Oct '05

Hi, I have a little problem, I need to adapt a setup that currently uses the native MySQL PASSWORD() function to encrypt passwords for e-mail accounts. I plan on using Dovecot with SQL to authenticate on my server, is there a password scheme that fits this authentication method? Any help is appreciated -- Tom Sommer

[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] pop3 behaviour
by Krzysztof Janiszewski - IT Partner 27 Oct '05

27 Oct '05

Hi! I'v installed dovecot over um-pop3 today. Dovecot has only pop3 enabled. imap will be enabled later. But there is one issue - on some accounts, after receiving mail to Outlook Express, mail is not deleted from /var/mail/username mbox file, and on most it is deleted. Why it works in that way? Best regards Krzysztof

[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

[Dovecot] alpha4 and zlib-plugin?
by Jeff A. Earickson 27 Oct '05

27 Oct '05

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

Hello! > Do you have reason to believe that the clients are issuing a delete > command and that the mail is incorrectly being left on the server OR do > they have a 'keep mail on server' option checked? I'm sure thet they have 'keep mail on server' unchecked. When uw-ipop3d was used, mail was correctly deleted. Best regards Krzysztof

[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
