[Dovecot] dovecot LDA: "temporary failure"
by David Koski 18 Mar '11

18 Mar '11

This really has me stumped and desperate. I upgraded Debian from 5 to 6 (squeeze) and now Dovecot LDA fails. I have checked permissions and the usual. Postfix SMTP, Dovecot POP3 and Dovecot IMAP work. Having to upgrade MySQL from 5.0 to 5.1 made me question that. Logging is of little help. I have turned on logging for LDA to a separate file. When I try to run the deliver command it returns nothing and appears to do nothing: ~$ cat /etc/hosts | /usr/lib/dovecot/deliver -f root@localhost -d dkoski(a)[domainhidden].com $ ..but then I don't know what to expect. The log files are owned by dovecot. I tried chmod'ing them to 777 in desperation. This was working before the upgrade to 1.2.15-4 from 1.0.15-2.3+lenny1. Postfix reports this stuff: Mar 17 22:37:38 host-mail postfix/smtpd[22160]: connect from mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:39 host-mail postfix/smtpd[22160]: 9D80C12AF610: client=mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:39 host-mail postfix/cleanup[22163]: 9D80C12AF610: message-id=<201103172237.29223.dkoski(a)[another-domainhidden].com> Mar 17 22:37:39 host-mail postfix/qmgr[21877]: 9D80C12AF610: from=<dkoski(a)[another-domainhidden].com>, size=1257, nrcpt=1 (queue active) Mar 17 22:37:39 host-mail postfix/smtpd[22160]: disconnect from mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:42 host-mail postfix/smtpd[22168]: connect from localhost[127.0.0.1] Mar 17 22:37:42 host-mail postfix/smtpd[22168]: 480D912AF612: client=mail.kosmosisland.com[63.228.175.169] Mar 17 22:37:42 host-mail postfix/cleanup[22163]: 480D912AF612: message-id=<201103172237.29223.dkoski(a)[another-domainhidden].com> Mar 17 22:37:42 host-mail postfix/qmgr[21877]: 480D912AF612: from=<dkoski(a)[another-domainhidden].com>, size=1873, nrcpt=1 (queue active) Mar 17 22:37:42 host-mail postfix/smtpd[22168]: disconnect from localhost[127.0.0.1] Mar 17 22:37:42 host-mail postfix/pipe[22169]: 480D912AF612: to=<dkoski(a)[domainhidden].com>, relay=dovecot, delay=0.04, delays=0.02/0.01/0/0.01, dsn=4.3.0, status=deferred (temporary failure) Mar 17 22:37:42 host-mail postfix/smtp[22164]: 9D80C12AF610: to=<dkoski(a)[domainhidden].com>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.4, delays=0.84/0.01/0/2.5, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=11197-13, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 480D912AF612) Mar 17 22:37:42 host-mail postfix/qmgr[21877]: 9D80C12AF610: removed And /var/log/dovecot/deliver.info: 2011-03-17 22:43:43 auth(default): Info: new auth connection: pid=22232 2011-03-17 22:43:59 auth-worker(default): Info: sql(dkoski(a)[domainhidden].com,127.0.0.1): query: SELECT email as user, password FROM view_users WHERE email='dkoski(a)[domainhidden].com'; 2011-03-17 22:43:59 auth(default): Info: client out: OK 1 user=dkoski(a)[domainhidden].com 2011-03-17 22:43:59 auth(default): Info: master in: REQUEST 73 22061 1 2011-03-17 22:43:59 auth(default): Info: master out: USER 73 dkoski(a)[domainhidden].com uid=5000 gid=5000 home=/home/vmail/[domainhidden].com/dkoski 2011-03-17 22:44:00 auth(default): Info: new auth connection: pid=22234 I tried reinstalling the package dovecot-common.

[Dovecot] Migrating to mdbox
by Chris Wilson 17 Mar '11

17 Mar '11

Hi all, I think it would be a good idea for me to move from mbox to mdbox, as I have 57,000 messages in my inbox, and clients hang for a minute whenever they request a CHECK, or Dovecot feels the need to run one itself. Looking at past threads: http://www.mail-archive.com/dovecot@dovecot.org/msg35212.html http://comments.gmane.org/gmane.mail.imap.dovecot/53936 it seems that the safest way is to run: sudo dsync -v -u chris backup mdbox:/home/chris/mdbox eliminate any errors that it reports, test the new mdbox access temporarily, and then switch my config in Dovecot. Ideally I'd like to do that just for me, without disrupting other users of this server (that I help to admin). This error occurs every time I run dsync, and I understand it, so I've elided it: dsync(chris): Error: open() failed with mbox file /home/chris/mail/admin: Permission denied dsync(chris): Error: Failed to sync mailbox admin: Internal error occurred. Refer to server log for more information.

[Dovecot] SSL Compatibility? SNI vs SAN (Subject Alternative Names) and multiple domains
by Thomas Harold 17 Mar '11

17 Mar '11

Getting ready to redo our mail server setup and I'm trying to wrap my head around the ins and outs and pratfalls involved in SSL, multiple domains, and Dovecot. I've taken a look at: http://wiki2.dovecot.org/SSL/DovecotConfiguration My basic understanding at this point is that: - With SSL for IMAP/POP3, it is limited to one certificate per IP address, because the SSL process starts as soon as the client opens the socket to the IP address. In order to support multiple domains / server names, you have to rely on SAN (Subject Alternative Names) in the server's SSL certificate. - If I use STARTTLS for IMAP/POP3 and Dovecot 2.x, then the SNI process will allow the client to specify that they want to talk to mail server XYZ and Dovecot will hand the correct certificate to the client. However, a lot of devices don't support SNI yet so this is fraught with peril and incompatibilities. So it seems like if I have fewer IP addresses then mail server names, I should stick with a single SSL cert and use SANs. (Wildcard certs are not an option due to the top level domain being different.) How big of an issue is a cert with half a dozen or a dozen SANs attached? Do most mail clients handle that sort of certificate properly in order to access their mailboxes? Reference links: http://www.digicert.com/subject-alternative-name-compatibility.htm

Hi, i am trying to share a maildir++ mailbox to other users but i can only subscribe to the root directory. The subfolders of the public mailbox do not appear in the exported list.

[Dovecot] dict crashes with multiple map definitions
by Birger Brunswiek 17 Mar '11

17 Mar '11

Hi, I get a crash in dict if I use multiple map sections. Each one of them works fine by their own. I managed to convince dovecot to create dump files to debug this, but I can't figure out how to do the same for dict. How can I do this? Anyway, perhaps someone already know's what's wrong by looking at what I do in the sql dict configuration.

Table created with: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 0, messages integer not null default 0, primary key (username) ); In dovecot.conf like in description is: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { # v1.2 + SQL: quota = dict:user::proxy::quotadict # v1.2 + file: quota = dict:user::file:%h/Maildir/dovecot-quota quota_rule = *:storage=10M:messages=1000 } File dovecot-dict-sql.conf has: # v1.2+ only: connect = host=localhost dbname=mails user=sqluser password=sqlpass map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } With corrected values about databasename, user and password. Where should to add information about sql query when autorization is not via myqsl (only shadow/password). There are in description info about additional file with user_query: dovecot-mysql.conf. Can anybody know how it should it look like and where to add it in config?

[Dovecot] inetd config - dovecot doesn't exits
by kjonca＠o2.pl 17 Mar '11

17 Mar '11

Is there any option for dovecot to exit when is unneded? I mostly use dovecot via shell process (ie. something like /usr/sbin/dovecot --exec-mail imap) But sometimes I want to use it remotely via tcp and I run dovecot via inetd. --8<---------------cut here---------------start------------->8--- localhost:imap stream tcp nowait root /usr/sbin/tcpd /usr/lib/dovecot/imap-login --8<---------------cut here---------------end--------------->8--- in inetd.conf works good, but dovecot stays, even if all clients ended their connections. How can I make dovecot to exit after last client disconnects?

[Dovecot] Attachment file size error in SIS
by Daniel L. Miller 17 Mar '11

17 Mar '11

I've got an attachment that triggers a "smaller than expected" error. It was a pdf I received some time ago. I copied the file from the dovecot storage, renamed it to something close to the original name (I don't remember what that was), then created a new mail with this as an attachment and saved it to the server. This created a new file, identical file size to the other - but continues to have the "smaller than expected" error. -- Daniel

[Dovecot] Configuration of LMTP Reject Code
by Petter Urkedal 17 Mar '11

17 Mar '11

Is it possible to change the reject codes from the Dovecot LMTP agent? In particular I would like to change the "550 5.1.1 <...> User doesn't exist." to a temporary failure, since we already validate email addresses on the mail front-end, and such errors are most likely due to a temporary glitch in the user database lookup. We use Postfix on the front-end, which is very configurable in this respect. I don't see a way to override the error code from LMTP, though, but suggestions are welcome.

[Dovecot] Using dovecot with wordpress/phpass passwords?
by Joan 17 Mar '11

17 Mar '11

Good afternoon, I am trying to setup dovecot to authenticate using the userdata from wordpress. It's being a bit mor difficult than I thought. This is the relevant part of the dovecot-sql.conf default_pass_scheme = CRYPT password_query = SELECT user_pass AS password FROM wp_users WHERE user_email='%u'; user_query = SELECT 501 as uid, 501 as gid,'maildir:storage=51200' as quota FROM wp_users WHERE user_email = '%u' I can see that the query is being procecessed according to the logs. Wordpress and others are using phpass to authenticate (http://www.openwall.com/phpass/) it is basically a salted md5 hash. Basically, after the process, a hash like this is obtained. $P$BiWISc3IsqRHxeEjq4VJP1Vi8gy4mg1 (for test123 password) I would like to know if dovecot would be able to read this, otherwise I could still make a custom checkpassword function but that would be non-optimal. Could someone guide me on this? If you need more details just ask. Thanks a lot, joan

[Dovecot] exim and /var/run/dovecot/auth-client permissions
by John Connett 17 Mar '11

17 Mar '11

I am attempting to configure a dovecot 2.0 + exim + fetchmail (demon) combination on openSUSE 11.4, initially with the standard dovecot package (2.0.9-3.4-x86_64) and now with the later server:mail build service package (2.0.11-1.1-x86_64). I followed the instructions in http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL but despite the changes in conf.d/10-master.conf the permissions on /var/run/dovecot/auth-client remain unchanged: $ ls -l /var/run/dovecot/auth-client Srw------- 1 root root 0 Mar 14 13:11 /var/run/dovecot/auth-client $ This is probably the cause of authentication failures from exim. I suspect it is something trivial but haven't yet been able to find the answer.

The 4 impacted files are: ./src/imap/imap-settings.h ./src/imap/imap-settings.c ./src/imap/cmd-list.c ./src/config/all-settings.c Here is the proposed description for the dovecot.conf file: # tb-lsub-flags: # Usually IMAP servers don't bother returning the flags attached # to each mailbox, but Thunderbird presently needs them in order # to correctly process the "folders of folders" case. Please tell me if the patch format is suitable or if you expect something else. Best regards and thanks again for your responsiveness.

[Dovecot] SASL abort causes 5s delay, triggered by UW libc-client
by Arne Nordmark 12 Mar '11

12 Mar '11

Since upgrding to Debian squeeze, the web mail system (Imp4/Horde3) suffers delays every time a new IMAP connection is needed. Tracing the authentication conversation, we find: 08:45:55.270609: 00000000 AUTHENTICATE GSSAPI 08:45:55.271277: + 08:45:55.271761: * 08:45:55.271782: 00000000 BAD Authentication aborted by client. 08:45:55.271815: 00000001 AUTHENTICATE PLAIN 08:46:00.271008: + and the PLAIN login succeeds. Imp4 is using php5-imap which is using libc-client, and the delays makes the interface so slow to hardly usable. For reasons best known to its authors, libc-client first initiates GSSAPI authentication, then checks if there is a Kerberos ticket it can use (there is none), then realizes its mistake and aborts SASL, and tries PLAIN. At this point dovecot delays for 5000ms. While not defending libs-client's odd behaviour of not checking for tickets first, it has probably done so for a long time, and dovecot from Debian lenny does not delay at this point. I am lost as how to get around this without changing the code. The "nodelay" parameter can not be used with PAM passdb, according to the documentation. I would be inclined to call always call client_auth_failed with nodelay=TRUE in the SASL_SERVER_REPLY_AUTH_ABORTED case.

[Dovecot] Dovecot 2.X, built from source, no extensions?

Greetings list. Pardon the ignorance. I am working on CentOS 5.2. Unfortunately the repo version of Dovecot is 1.0.X. This works fine mind you but it doesn't have ORDEREDSUBJECT Threading support, which I need. I downloaded 2.0.11 and built from source, but now I don't see any Threading support, not even REFERENCES.

[Dovecot] permission recomendation for dovecot configuration files and binaries
by Arkadiusz Miskiewicz 10 Mar '11

10 Mar '11

I'm trying to figure out which permissions will be the best to handle most of tasks (for use in rpm package) for configuration files. Basically /etc/dovecot/ dir /etc/dovecot/* files /etc/dovecot/conf.d/ dir /etc/dovecot/conf.d/files dovecot binaries, deliver mainly For example deliver needs to read configuration files and needs to write into destination. Doesn't seem to be sane to allow MTA user read dovecot configs but that is requires for deliver to work etc. Are there any sane/tested recommendations that would fit most situations (remember, that's going to be rpm package default config) ? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Usually this machine's load is only between 1 and 4, which is quite ok for a quad core. It only happens when dovecot start generating errors, and pop3, imap and http get stuck. It went up to 200, and I was still able to stop web and mail daemons, then restart them, and everything was back to normal.

If you're not doing local sync with TB and you have GLODA disabled, TB is going to show you exactly what's in your Dovecot mailbox. If the message doesn't disappear from your TB view sometime after deleting it on your smartphone, then I'd say it's very likely that Dovecot didn't receive the delete and/or expunge command from the phone. Check your Dovecot logs and see what the phone is actually sending, or not sending. Both of you mentioned problems specifically WRT smartphones. It's likely the IMAP implementation in these phones is simply buggy, or your network coverage is spotty. I don't use a smartphone so I can't really say. What smartphone are you each using? -- Stan
