[Dovecot] CRAM-MD5 HMAC-MD5 password algorithm for PHP
by Hajo Noerenberg 18 Apr '08

18 Apr '08

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] 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 and postfix virtual mailbox domains, system users
by Dave 18 Apr '08

18 Apr '08

Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username/, there's a maildir under that area and incoming mail gets delivered by postfix to that area. In the first case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account at all. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd and the specific maillog error is this: Apr 11 23:48:17 s15298471 dovecot: pop3-login: Login: user=<user>, method=PLAIN, rip=66.139.186.37, lip=74.208.64.129, TLS Apr 11 23:48:17 s15298471 dovecot: POP3(user): stat(/home/vmail//user/cur) failed: Permission denied Apr 11 23:48:17 s15298471 dovecot: POP3(user): stat(/home/vmail//user/cur) failed: Permission denied Apr 11 23:48:17 s15298471 dovecot: POP3(user): Couldn't open INBOX: Internal error occurred.

[Dovecot] remove mails from shared folders
by Patrick Fischer 18 Apr '08

18 Apr '08

Hallo dovecot This is my first post on this list. I'm new to IMAP servers and i read lots of howtos. If I use the wrong term for some features please tell me the right term. I have installed dovecot under ubuntu 7.10 and it works fine. dovecot + fetchmail + postfix I would like to use shared folders the way that we have an email pool for info(a)mydomain.com user1(a)mydomain.com -> User1 user2(a)mydomain.com -> User2 user3(a)mydomain.com -> User3 info(a)mydomain.com -> Pool (look at this http://decembersoul.dyndns.org/wiki/images/c/c6/IMAP1.jpeg ) The users can see and process emails from the email pool. To process an email the user move the email from the email pool to his own inbox. This should make sure that only one user process a email. Shared folders are created by symlink. The problem is that, if a user move an email out of the email pool, the other users still can see the mail in the pool. It takes a long time to remove the mail from the pool for every user. Move TO the pool works immediatley. The user can make a "compress folder" to remove the emails but this can't be the soulution. Maybe this is a client failed (tested only with thunderbird) Best regards Patrick Fischer

[Dovecot] Minor namespace issue - inconsistent default value
by Joel Johnson 18 Apr '08

18 Apr '08

I burned some time yesterday over a documentation inconsistency. The dovecot-example.conf file shipped with dovecot (checked with 1.1rc4 and the April 3 nightly), includes an indication at the top that the commented values listed are the defaults for the settings. Line 248 of this file has the inbox setting for a private namespace which indicates that the default value for this setting is true. However, line 358 of ./srv/master/master-settings.c sets the default value of the namespace inbox variable to false. With a single private namespace (what I was setting up), one wants this value to be true, however when using multiple namespaces the default should likely remain false. I propose keeping the coded default and changing the line in the example configuration file to indicate false. Before I determined that this was the issue, I had a single namespace defined (but not as INBOX), and dovecot (both deliver and imap) created and read from a .INBOX directory under the Maildir. Thanks, Joel

[Dovecot] more than one ldap database.
by Mauro Sanna 18 Apr '08

18 Apr '08

If I have two databases in my ldap, ex: dc=dominio1,dc=it is the first database and dc=dominio2,dc=it is the second one. Can I put these two search bases in dovecot-ldap.conf?

[Dovecot] Bah! Outlook
by Jason Wohlford 18 Apr '08

18 Apr '08

Hi All, I run a little hosting company. I use Dovecot 1.0.10* with IMAP exclusively. Lots of my customers use Outlook or Outlook Express. This poses a problem. These programs don't and have absolutely no workarounds to move messages to a trash folder when deleted. They only mark the message for deletion. Then, users have to purge the message to actually delete it. Outlook has a way to hide deleted messages and also auto-purge them when moving to a different folder. That just doesn't cut it. (Thanks Microsoft! :-p ) So, I'm thinking Dovecot could pick up where Microsoft left off. It seems to me there needs to be two things done. First, a system that automatically copy a message marked for deletion from one folder (e.g. INBOX) to a trash folder (e.g. Trash, Deleted Messages, etc.) Dovecot's lazy_expunge might already do this, but I couldn't quite discern it from the wiki docs. Second, a way to only do this when Outlook or Outlook Express is the one who is deleting a message. Possibility? Comments? Cheers, Jason P.S. Thanks for the great software! *Yes, I know. I need to upgrade to Dovecot 1.0.13. -- Jason Wohlford <jason(a)wohlford.org> <http://wohlford.org>

[Dovecot] keep users from deleting email
by Adam Williams 17 Apr '08

17 Apr '08

I looked on the dovecot website, but didn't find an answer. With dovecot 1.0, is there a way to keep users from deleting their email? So that when they click the delete button on their email client, nothing happens/dovecot refuses to delete email, etc?

[Dovecot] Dovecot 1.1rc3 "Out of Memory" crashes from pop3-login?

We recently began seeing server crashes in our cluster related to "pop3-login", which is causing "oom-killer" to be invoked. The server only recovers after a reboot.

Is there any possiblity to run more than one instance of dovecot in gentoo (I was trying to run second instance but I don't know how to force it to use other pid file than /var/run/dovecot/master.pid) I'm using dovecot from portage dovecot-1.0.13-r1.

[Dovecot] CRAM-MD5 Password Generation Algorithm
by Douglas Willcocks 17 Apr '08

17 Apr '08

Hi, I'm just in the middle of setting up dovecot to serve IMAPS -- Actually I've finished apart from one thing: CRAM-MD5 passwords. I'm using SQL as a backend for the password storage, and I don't want to store the passwords in plaintext. I've also configured dovecot to be rather restrictive when it comes to authentication methods (only CRAM-MD5 is allowed). To generate the passwords to go into the database I can use the dovecotpw utility, but I'm wanting to stick some sort of minimal admin interface on the server to be able to manage the users etc without having to use the CLI. I've looked at the theoretical explanation of the hashing algorithm, and I've read through the source code that dovecotpw uses to generate the passwords with the intent of creating a higher level language library (Perl, Ruby, PHP ... whatever)) to generate passwords, but I don't seem to be able to replicate the functionality, and there don't seem to be any existing libraries that generate consistent results (that I've found). I don't have that much experience with C, and so I'm sure that I must have misunderstood how dovecotpw does its stuff. Perhaps someone could explain how the algorithm works? Or point me in the right direction? Thanks, Douglas Willcocks

[Dovecot] Dovecot-deliver lookup fails
by Wouter Amsterdam 17 Apr '08

17 Apr '08

Hi all, I'm still trying to get Dovecot-deliver to work in my config. I have found the problem to be in the maildir lookup for Dovecot-deliver as logged in /var/log/maillog: "Apr 15 16:30:34 termserv dovecot: auth(default): static(user(a)zesgoes.nl): passdb doesn't support lookups, can't verify user's existence" The thing I don't get, is that if I remove the virtual_transport modifications in /etc/postfix/master.cf and /etc/postfix/main.cf and the socket listen in /etc/dovecot.conf, all works well. So dovecot has no problems looking up my users on a LDAP server as a passdb backend, but failes when using the same passdb for dovecot-deliver. How come? TIA, Wouter
