[Dovecot] Cannot connect to dovecot imap server -- nothing in log

Hello all, I'm trying to connect to a dovecot server I've just installed, using evolution.

[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
