[Dovecot] IMAP clients generate user home folders one level higher than needed
by andel 22 Apr '08

22 Apr '08

Hi (Of course not the clinets generate the folders, dovecot does, but I wanted to have the title not be too long.) I am using static userdb: userdb static { args = uid=vmail gid=mail home=/srv/vmail/%d/%n } and I have configured the hostname in protocol lda. Now when mail arrives for a known virtual user, the home directory with all subdirectories is being created correctly unter /srv/vmail/$domain/$vuser. But when connecting from an IMAP client (I have tested Thunderbird and Outlook) a new home directory with apparently correct subfolders is bring created unter /srv/vmail/$vuser ! The connection works, I just don't see the mails which arrived since the client is mapping a directory one level higher than needed. Where do I have to look for the cause? I did not find anything reasonable yet. Thank you in advance, David

[Dovecot] odd behaviour with antispam plugin
by ZyanKLee 22 Apr '08

22 Apr '08

hey, in my dspam database there has been some odd behaviour: during training dspam had created an uid entry named by the local part of the email. i.e.: user1 I use a virtual setup using dovecot, postfix and postfixadmin. On my first try I set up a database for dspam itself and there this happened. After I couldn't figure out how to solve this, I merged the database into the postfixadmin database. But using just the username for identifying email adresses is a bit critical within a virtual environment with multiple domains, isn't it? if one would not merge the databases - how could he solve this problem?

[Dovecot] Moving Maildir email messages and backing things up.
by Karl Schmidt 22 Apr '08

22 Apr '08

I just moved to dovecot with Maildir. I think this is probably a stupid question, but I couldn't find an answer after an hour of googling and searching the wiki. What would happen if I ran a script that did this: mv ~/Maildir/.folder_one/cur/* ~/Maildir/.folder_two/cur/ My hunch is it might break things. What if dovecot was stopped? ,.,.,. Where can I find a list of files in ~/Maildir/ and a note on what they are? (And similarly for a ~/Maildir/.folder) I'm wondering if everything needs to be backed up, or if I can/should skip the indexes. What happens if any of these files changes during the backup? (I'm thinking I shouldn't have to stop dovecot for a backup). ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] antispam plugin ehancement
by ML 22 Apr '08

22 Apr '08

I'm not a developper so I can't do it by myself, but I wonder if it could be possible to use tagSpam and tagNospam DSPAM feature to ehance user's dspam lerning experience. I even don't know if this must be done by DSPAM itself or by dovecot, but let me explain : The feature would be done by a signature replacement into tagSpam and tagNospam text, so the user would simply have to click on the link at end of the mail to learn DSPAM : # dspam.conf tagSpam on tagNonspam on # msgtag.spam If this message was classified SPAM by mistake, please click here : http://example.com/dspam-retrain.cgi?sig= {DSPAM_SIG} # msgtag.nonspam If this message should have been classified SPAM, please click here : http://example.com/dspam-retrain.cgi?sig= {DSPAM_SIG} I think a click is easier and faster than a forward, what do you think of such an implementation ?

[Dovecot] Feature Request - starting dovecot, config file behavior
by Charles Marcus 21 Apr '08

21 Apr '08

Hey Timo, I was wondering how much trouble it would be to again emulate the way postfix does something - in this case, the way it reads its config file when starting up. Current behavior: Postfix: If postfix encounters the same setting defined more than once, the last one wins. Dovecot: If dovecot encounters the same setting defined more than once it gives an error (also when using the 'dovecot -n' command). I like to add all of my changes to the very bottom of the config file, but otherwise leave the config file as is... this makes it very easy when updating - I can easily keep all of the new default config file, and simply merge my customizations at the end. So - how hard would it be to make dovecot simply accept the last defined setting read, instead of refusing to start? Thanks much, and glad to have you back in action! -- Best regards, Charles

[Dovecot] mailtrain with dovecot antispam plugin
by Hugo Monteiro 21 Apr '08

21 Apr '08

Hello all, and Johannes if you're around, I was trying to set up the "new" antispam plugin with the mailtrain backend, and i was trying to use the sendmail binary that's part of a qmail system. The message wouldn't get sent and i kept getting exit error 100 from the /var/qmail/bin/sendmail binary. To try to figure out what was happening, i mean a fake sendmail program, which is nothing more than a bash script to capture the command call input. The script is rather simple, it just places the calling parameters into a txt file and the stdin into another. code is #!/bin/bash echo $* > /tmp/sendmail-parms.txt exec cat<&0 >> /tmp/sendmail-msg.txt exit 0 So i tried a retrain and went to see what those txt files had. The parms.txt file was fine apparently, with cat /tmp/sendmail-parms.txt i got -f hm(a)hmonteiro.net notspam-hm(a)hmonteiro.net Then i did the same to the message file, with cat /tmp/sendmail-msg.txt, and i got the follwing Return-Path: <hugo.monteiro(a)fct.unl.pt>Delivered-To: hm(a)hmonteiro.net Received: (qmail 21616 invoked from network); 19 Apr 2008 16:21:17 -0000 Received: (simscan 1.4.1 ppid 21609 pid 21611 t 0.1451s) (scanners: regex: 1.4.1 attach: 1.4.1 clamav: 0.92.1 /m:46/d:6803); 19 Apr 0108 16:21:17 -0000 Received: from femme-fatal.resnet.costabasto.com (HELO femme-fatal) (192.168.0.20) by hmonteiro.net with SMTP; 19 Apr 2008 16:21:17 -0000 Subject: buy some viagra HURRAY X-DSPAM-Result: Innocent X-DSPAM-Processed: Sat Apr 19 17:21:17 2008 X-DSPAM-Confidence: 0.4945 X-DSPAM-Probability: 0.0330 X-DSPAM-Signature: 480a1bfd216125429498786 viagra sale really HURRAY cheap! only $5!

[Dovecot] building a simple antispam plugin
by Alexander Prinsier 21 Apr '08

21 Apr '08

Hello, I'm trying to build another antispam plugin, but some things are a bit unclear. In backend_handle_mail I put store the signature returned from signature_extract into my antispam_transaction_context. In backend_commit it appears that the signature is empty. (It wasn't in backend_handle_mail). Somehow between backend_handle_mail en backend_commit it has been cleared... When I use i_strdup it appears to work. Anyone can tell me where this clearing happens? Is i_strdup the right way to do it then? Thanks, Alexander

[Dovecot] How to deal with mail to unknown virtual recipients?
by Andreas Ntaflos 19 Apr '08

19 Apr '08

Hello list, I am not quite sure whether this is a questions for Dovecot or Postfix. I have set up, virtual hosting for one domain (for test purposes) using a passwd-file as passdb and a static userdb (see dovecot -n at the end) along with Postfix in a manner described in [1], i.e. a non-Postfix mail store. Other than that I also do hosting for the canonical domain which is for users with a regular Unix account on the system (looked up via PAM) The virtual domain shall be "example.org", with two users "alice(a)example.org" and "bob(a)example.org". But today I received spam mail (which was correctly identified as such by amavisd-new) for "info(a)example.org" and "sales(a)example.org", two recipient addresses that do not exist. According to [1] "it's left up to the non-Postfix delivery agent to reject non-existent recipients from local submission or from local alias expansion." How to deal with such a situation? The sender address was clearly forged so returning a failed delivery message is pointless. The messages are now hanging around in the queue with a status of "deferred: temporary failure". The logs show: dovecot: auth(default): passwd(info(a)exmaple.org): unknown user dovecot: auth(default): passwd-file(info(a)mexample.org): unknown user dovecot: auth(default): static(info(a)example.org): passdb doesn't support lookups, can't verify user's existence postfix/pipe[25328]: C7EA18BC0B5: to=<info(a)exmaple.org>, relay=dovecot, delay=1.4, delays=0.07/0.02/0/1.3, dsn=4.3.0, status=deferred (temporary failure) The dovecot relay is defined in /etc/postfix/master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} The question, once again, is: what to do in such a situation? A catch-all address could be set up, but to what end? It would just catch a lot of spam over time. What is the correct way to deal with this? More importantly: is there even anything Dovecot could (or should) do?

[Dovecot] Delete antispam emails
by David Reid 19 Apr '08

19 Apr '08

I'm using dovecot with the antispam plugin to allow for training, but how do I delete emails once they've been trained? If I delete them from the folder using an email client they get retrained as valid emails when they're moved to the trash folder! D'oh. I'm looking, ideally, for a solution that doesn't need a script to be run per user as I have a number of users using this feature. Also, the cleanspam script doesn't seem to be able to find the folder I'm using ('SpamTrain') so what format should I use? Thanks. david

Hi, based on the recent discussion by Bill Cole and Douglas Willcocks I've quickly put together a PHP script which generates MD5 'contexts' for Dovecot's password files: http://www.noerenberg.de/hajo/pub/dovecot_hmacmd5.php.txt The script has not been tested extensively, so use it on your own risk :) Most of the code has been shamelessly stolen from various sources. You'll find the names in the header of the script. Hajo

[Dovecot] Message UID Question
by Joe Allesi -X (joallesi - Coyote Creek Consulting at Cisco) 18 Apr '08

18 Apr '08

I have referred to the wiki and the RFC, but I still can't find the exact answer I'm looking for. From what I know, Dovecot uses the IMAP standard of 32 bit integers to uniquely identify messages. After a message is deleted from the mbox, can this UID ever be reissued to a new message or is that UID retired? What about after the 2 billion limit is reached? Thanks!

[Dovecot] Please help: LDAP configuration _almost_ works.
by Jack McKinney 18 Apr '08

18 Apr '08

Red Hat Linux release 7.2 (Enigma) OpenLDAP 2.3.38 Dovecot 1.0.12 SHORT VERSION ----- ------- Here is my dovecot-ldap.conf: hosts = ldap.lrtz dn = cn=varmail,ou=users,dc=lorentz,dc=com dnpass = ********* ldap_version = 3 auth_bind = yes pass_filter = (&(objectClass=inetOrgPerson)(mail=%Lu)) base = ou=users, dc=%Dd scope = onelevel I have tested using the above information with ldapsearch, and it works fine. However, when dovecot tries to authenticate the user, the LDAP server receives the query and responds to it (according to the LDAP log file), but dovecot just hangs there. 180 seconds later, it drops the IMAP client. E.g.: The dovecot log shows: Apr 3 08:13:21 fourier dovecot: auth(default): new auth connection: pid=15774 Apr 3 08:13:30 fourier dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=x.x.x.x^Irip=y.y.y.y^Iresp=<hidden> Apr 3 08:13:30 fourier dovecot: auth(default): ldap(jackmc(a)lorentz.com,y.y.y.y): bind search: base=ou=users, dc=lorentz,dc=com filter=(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) Apr 3 08:16:30 fourier dovecot: imap-login: Disconnected: Inactivity: method=PLAIN, rip=y.y.y.y, lip=x.x.x.x, TLS The OpenLDAP log shows that the query is received and that it returns a match: Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH base="ou=users,dc=lorentz,dc=com" scope=1 deref=0 filter="(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))" Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SRCH attr=uid Apr 3 08:13:30 fourier slapd[14039]: conn=7 op=3 SEARCH RESULT tag=101 err=0 nentries=1 text= LONG VERSION ---- ------- My users login using their email address as username. Each domain has their own LDAP subtree. Each user has an entry in the ou=users subtree of the domain subtree, and has a mail: field (inetOrgPerson) listing their email address/login name. I am trying to use auth_bind: when I login with jackmc(a)lorentz.com, dovecot should search for mail=jackmc(a)lorentz.com in the onelevel below ou=users,dc=lorentz,dc=com and find me as "cn=Jack McKinney,ou=users,dc=lorentz,dc=com". I have created an entry in LDAP (varmail) that should be able to do this query. Indeed, from the command line, it works: ldapsearch -h ldap.lrtz -b 'ou=users, dc=lorentz, dc=com' -D 'cn=varmail,ou=users,dc=lorentz,dc=com' -x -W -s onelevel '(&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com))' Enter LDAP Password: # extended LDIF # # LDAPv3 # base <ou=users, dc=lorentz, dc=com> with scope oneLevel # filter: (&(objectClass=inetOrgPerson)(mail=jackmc(a)lorentz.com)) # requesting: ALL # # Jack McKinney, users, lorentz.com dn: cn=Jack McKinney,ou=users,dc=lorentz,dc=com objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson cn: Jack McKinney givenName: Jack McKinney sn: McKinney mail: jackmc(a)lorentz.com # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 It appears that dovecot performs the above query successfully, but then never uses the password and retrieved DN to attempt to bind and authenticate the user. Instead, it just times out. (See log files above in the SHORT VERSION). I tried to add pass_attrs, in case there was a bug in dovecot where it ignores the reply if there are no pass_attrs (even though none are needed), but it still fails the same way. Timo Sirainen suggested that I add a debug line to src/auth/db-ldap.c ldap_input() around line 372: msgid = ldap_msgid(res); // added line: i_info("LDAP: Received reply %d", msgid); I did this. Now, when the server first starts up, this line is logged. However, it is not logged when it queries the LDAP server as a result of an IMAP connection needing authentication. -- Jack McKinney GPG 1024D/99C6A174 jackmc(a)lorentz.com YM:lfaatsnat2006 AIM:jackmclorentz "There is no parameter that makes it impossible for you to perform still more excellently." -Mario Cuomo, on the lack of a clock in baseball

[Dovecot] authentication troubles

hi i have a strange problem with my dovecot installtion: i configured it to accept digest-md5 authentication only but for some reason mailclients (i tried mutt and thunderbird so far) want to log with PLAIN (which fails of course). authentication basically works, e.g. if i explicitly set set imap_authenticators="digest-md5 in .muttrc everything works... any idea what is going wrong? config attached below tia yours albert # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s ssl_listen(default): *:22993 ssl_listen(imap): *:22993 ssl_listen(pop3): *:22995 ssl_cipher_list: ALL:!LOW login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 107 last_valid_uid: 107 mail_location: maildir:%h/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 namespace: type: private location: maildir:%h/Maildir inbox: yes auth default: mechanisms: digest-md5 realms: mailstore.nicenamecrew.com default_realm: mailstore.nicenamecrew.com username_format: %Lu verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/virtual/%d/%n socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 group: vmail

[Dovecot] Dovecot LDA / Deliver question
by Stacy Trippe 18 Apr '08

18 Apr '08

Problem described: I am trying to get Postfix + Dovecot + MySQL setup to work together in a virtual mail hosting platform. I am running Postfix 2.3.x, and MySQL 5.0.x. I am trying to use Dovecot's LDA for delivery to the users vmail home directory -- usually under /var/vmail/domain.com/j/jdoe for home and /var/vmail/domain.com/j/jdoe/.maildir for mail location, using MAILDIR format. However, I cannot get Dovecot's LDA to write the maildir folders/files into the right location. It wants to write in MBOX format to /var/vmail/mail/inbox instead. When I force the mail_location variable...it just uses the system 'vmail' user (uid: 1101) and 'vmail' group (gid: 1101) that I assigned for the virtual mail user. mail_location = maildir:/var/vmail/%d/%1n/%n I am not sure where to go to troubleshoot Dovecot LDA...and how to turn up/down the verbosity of debug messages (albeit now I am logging the deliver info to /var/log/dovecot-deliver.log). Does anyone know what I am missing? Can Dovecot LDA be told how to deliver mail to the users maildir folder? Here is my postfix master.cf: ... dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/libexec/dovecot/deliver -f ${sender} Here is my postfix main.cf (as it pertains to dovecot LDA): virtual_transport = dovecot mailbox_command = /usr/libexec/dovecot/deliver smtpd_sasl_type = dovecot dovecot_destination_recipient_limit = 1 dovecot --version 1.0.rc15 dovecot -n # /etc/dovecot.conf log_path: /var/log/dovecot.log login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: SMTP ready. login_process_size: 64 login_processes_count: 5 login_max_connections: 512 mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: passwd userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=mailsql user=mailquery password=m@1l default_pass_scheme = PLAIN-MD5 password_query = SELECT email as user, passwd AS password, concat('/var/vmail',homeDir) as userdb_home, 1101 AS userdb_uid, 1101 AS userdb_gid, concat('maildir:/var/vmail',mailDir) as userdb_mail FROM users WHERE (username = '%u' OR email = '%u' OR email = concat('%u','@domain.net')) AND status = 'A' AND type = 'M' user_query = SELECT concat('/var/vmail',homeDir) as home, 1101 AS uid, 1101 AS gid, concat('maildir:/var/vmail',mailDir) as mail FROM users WHERE username = '%u' ....

[Dovecot] Feature request
by Ruud Boon 18 Apr '08

18 Apr '08

Hi! I hope I'm using the right mailing for a feature request. I'm using dovecot on my server for a year now and I'm very happy with it. Its extremely stable and fast. Ok what is my situation why I'm asking a feature.. Users are retrieving mail using pop3 over the external ip address. When the user connects to there webmail. The webmail client (Squirrelmail) is using imap on the localhost. I would like to give some users the option to use imap over the external ip, I want to set option in my MySql backend configuration. As far as I know there isn't a possible solution on dovecot right now that's why I hope you can build a extra config parameter that gives me the possibility to allow users to retrieve email by imap by ip. So all users can do an imap request on localhost (for webmail) and some user are allowed to do an imap request over the external ip. I hope that my request is clear and I'm posting in the right group. With regards, Ruud Boon

[Dovecot] Dovecot sending OK while idling

When an IDLE command is active, Dovecot sends an OK every two minutes. Is it possible to disable this? I'm trying to eliminate unnecessary traffic on a link that's charged by the kilobyte. Using Dovecot 1.0.7. -- John W. Temples, III
