[Dovecot] Listening only on localhost
by tobias-mail＠gmx.net 02 Nov '07

02 Nov '07

Hi! I've got dovecot 1.0.rc15. I want dovecot to listen only on localhost for imap, and on any interfaces for imaps. So I put the following into my config: protocol imap { listen = 127.0.0.1:143 ssl_listen = *:10993 .. } dovecot -n correctly reports: listen: 127.0.0.1:143 ssl_listen: *:10993 But I can still do a 'telnet MY_HOST 143' from the outside, and 'netstat -pltn | grep dovecot' reports: [ip changed ;)] tcp 0 0 77.my.ip.253:10993 0.0.0.0:* LISTEN 4847/dovecot tcp 0 0 77.my.ip.253:143 0.0.0.0:* LISTEN 4847/dovecot Am I doing something wrong?

[Dovecot] caching custom headers (via plugins)
by Paolo 02 Nov '07

02 Nov '07

hi, currently dovecot caches on disk some most common headers. Is it possible to tweak such headers list via plugins, eg to cache custom X-* headers, or do I need to hack the actual index/cache src? if so, which are the .c/.h files to touch? thanks -- paolo GPG/PGP id:0x1D5A11A4 - 04FC 8EB9 51A1 5158 1425 BC12 EA57 3382 1D5A 11A4

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta5.tar.gz.sig APPEND should be working now. Also lots of fixes to handling namespace prefixes and namespaces where virtual separator differs from real separator. zlib plugin now supports opening compressed maildir files. This is done for files that have Z flag. SORT still assert-crashes sometimes. Would be great if someone could show me how to reproduce it. SEARCH TEXT or Squat indexes apparently still have some problems, but I couldn't reproduce them (http://dovecot.org/list/dovecot/2007-October/026254.html)

[Dovecot] Bug within Authentication Caching
by Matthias Waffenschmidt 02 Nov '07

02 Nov '07

Hello, there seems to be a bug in the authentication caching code when using it in combination with username_translation (using the current version 1.0.7 on FreeBSD 6). I've set username_translation to +@:@ to allow usernames of the form test+dom.ain or test:dom.ain (historical reasons force us....). If someone has a successful login using the username test(a)dom.ain, the subsequent authentication information is read from the cache, no matter which of the 3 possible usernames the client uses the next time. But if someone has a successful login using the username test+dom.ain, the following data has or has not been found in the cache: test+dom.ain: miss test(a)dom.ain: miss test:dom.ain: hit If the first username is test:dom.ain the behaviour is the following: test:dom.ain: miss test(a)dom.ain: miss test+dom.ain: hit I've added the information if the username changes for better debugging possibilities. In practice the username is of course always the same. The complete authentication part of the tested config: auth default: cache_size: 10000 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@:+ username_translation: +@:@ verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /var/pop/%d/Accounts.passwd userdb: driver: static args: uid=70 gid=70 home=/var/emtpy It looks as if Dovecot does some wrong username translations before inserting/lookup up the data in the cache. BTW: a SIGUSR2 signal to the dovecot-auth process does not give any information as suggested in http://wiki.dovecot.org/Authentication/Caching. Please do not only answer to the list as I am not subscribed. Thanks. -- Gruss / Best regards | LF.net GmbH | fon +49 711 90074-411 Matthias Waffenschmidt | Ruppmannstr. 27 | fax +49 711 90074-33 mw(a)LF.net | D-70565 Stuttgart | http://www.lf.net

[Dovecot] dovecot + LDAP + SASL?
by hadmut＠danisch.de 02 Nov '07

02 Nov '07

Hi, I would like to setup an IMAP server with SASL and LDAP support. As far as I can see dovecot supports SASL and LDAP, but not the way I need it. If I understand dovecot correctly, it has it's own set of SASL mechnisms and uses the LDAP server just to store the plaintext password. In case of authentication dovecot fetches the plaintext password from LDAP and then performs the SASL steps internally. I need to support proprietary SASL mechanisms built into an LDAP server, which are not based on just a single password. So is there a way to configure dovecot to just pass SASL through to LDAP, allowing the IMAP client to talk SASL with the LDAP server through dovecot? regards Hadmut

[Dovecot] Successful experience with auth_winbind module
by Dmitry Butskoy 02 Nov '07

02 Nov '07

Hi, Recently the support of Samba's ntlm_auth helper was added to dovecot-auth (mech-winbind.c etc.). It is alrready in 1.1, the patch for 1.0 is here: http://dovecot.org/patches/1.0/dovecot-1.0.3-winbind.patch . It allows auth against NT or AD domain. I would like to infrom all that we successfully use this new feature during 2 month and ~300 users 24x7 (an energy power company). No any failures at all! This feature allows to specify "SPA" (Secure Password Authentication) option in OE, and to avoid explicit user passwords in mail accounts. Some random notes: - In the mixed environment (both plain and ntlm methods in use), you have to specify: mechanisms = plain ntlm login i.e. "ntlm" before "login". When sending mails, OE just catch first seen and try to use it, even if you specify to use SPA in the mail account preferences. - It seems that MS Outlook requires the specifying of password even when SPA is in effect - When OE has several identities, and one of the identities has SPA for SMTP set (outgoing mail), it wins over all another identities. - "The Bat" mailer supports NTLM for reading, not sending, and requires password too. Regards, Dmitry Bustkoy http://www.fedoraproject.org/wiki/DmitryButskoy P.S. We use NTLM only, GSS-SPNEGO still not tested.

[Dovecot] mail_location and master_user rel 1.0.x

login me(a)mymail.net*theboss thebossespwd this is a great piece of software, but it has some frustrating issues. i have included my two configurations below, just FYI. the one (older) system is 1.0rc7 on mandriva 2007.0 and postfix 2.3.3 and amavisd and spamassassin and using a maildir configuration the newer system is 1.0.5 (soon to be 7) on mandriva 2008.0 and postfix 2.4.5 amavisd and spamassassin and using a maildir configuration first, i followed the instructions in this document http://wiki.dovecot.org/Authentication/MasterUsers to the letter and it works for neither the old server nor the new. specifically i was using the first example configuration. all i ever got was: Connected to mail.mailserver.com Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS STARTTLS AUTH=LOGIN AUTH=PLAIN AUTH=DIGEST-MD5] Dovecot ready. login him(a)mailserver.com*theboss thebossespwd login BAD Error in IMAP command received by server. and the auth_debug information was completely useless. if someone goes to the trouble of writing great examples they really should test to make sure they actually work. secondly: this configuration on the old server (1.0rc7) works fine: ##

[Dovecot] receive date wrong in outlook
by Farkas Levente 01 Nov '07

01 Nov '07

hi, we migrate from exchange to dovecot. we do it with imapsync. first we try to do it with --syncinternaldates, but this fails on many messages with invalid date, so we drop this option. unfortunately after this those users who use outlook see the received date as the date we do the migration in stead of the real received date. other clients eg webmail, thunderbird etc sees the right date. so my question what can i do? it's a dovecot bug or outlook and if outlook's bug is there any workaround fro this? thanks in advance. -- Levente "Si vis pacem para bellum!"

Hi There, I'm using dovecot-imapd 1.0.rc15-2etch1 under Debain Etch AMD64 platform, recently, once of our user reported that there have "Unknown Namespace" problem with the new mail.app under leopard. So, is there a workaround at dovecot or I need to upgrade to a latest version of dovecot? Regards, Dino.

[Dovecot] dovecot-1.0.3 & apacheds ldap
by sergey ivanov 31 Oct '07

I have problem with dovecot-1.0.3 and apacheds ldap server. If I change just uris in dovecot-ldap.conf to point to fedora-ds server, everything works O.K. I've tried with apacheds ldap server versions 1.0.2 and 1.5.0 command line search with parameters taken from dovecot.debug log gives me all needed attributes. Comments and help welcome. Here is my data: --- # /opt/dovecot/sbin/dovecot -n # 1.0.3: /opt/dovecot/etc/dovecot.conf log_path: /tmp/dovecot.log info_log_path: /tmp/dovecot.debug protocols: pop3 pop3s imap imaps ssl_cert_file: /etc/ssl/parkheights.cert ssl_key_file: /etc/ssl/parkheights.key login_dir: /opt/dovecot/var/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: maildir:/var/spool/imap/%n/.imap mail_debug: yes mail_executable(default): /opt/dovecot/libexec/dovecot/imap mail_executable(imap): /opt/dovecot/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: ldap args: /opt/dovecot/etc/dovecot-ldap.conf userdb: driver: ldap args: /opt/dovecot/etc/dovecot-ldap.conf userdb: driver: prefetch socket: type: listen master: path: /opt/dovecot/var/run/dovecot/auth-master mode: 384 user: vmail group: vmail --- # grep -v '#' /opt/dovecot/etc/dovecot-ldap.conf |grep -v '^\s*$' hosts = 192.168.10.43:389 dn = uid=admin,ou=system dnpass = Ahma3zoc sasl_bind = no auth_bind = no ldap_version = 3 base = ou=people,dc=parkheights,dc=dyndns,dc=org user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%Ln)) pass_attrs = uid=user,gidNumber=userdb_gid,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid default_pass_scheme = MD5 --- # tail -5 /tmp/dovecot.debug dovecot: Aug 03 08:07:10 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AHNlc(here_also_skipped_something)3N1Pg== dovecot: Aug 03 08:07:10 Info: auth(default): ldap(seriv,127.0.0.1): pass search: base=ou=people,dc=parkheights,dc=dyndns,dc=org scope=subtree filter=(&(objectClass=posixAccount)(uid=seriv)) fields=uid,gidNumber,userPassword,homeDirectory,uidNumber dovecot: Aug 03 08:07:10 Info: auth(default): ldap(seriv,127.0.0.1): result: uid(user)=seriv gidnumber(?unknown?)= userpassword(?unknown?)= homedirectory(?unknown?)= uidnumber(?unknown?)= dovecot: Aug 03 08:07:12 Info: auth(default): client out: FAIL 1 user=seriv temp dovecot: Aug 03 08:10:10 Info: imap-login: Disconnected: Inactivity: user=<seriv>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured --- # tail -3 /tmp/dovecot.log dovecot: Aug 03 08:06:53 Warning: auth(default): Killed with signal 15 dovecot: Aug 03 08:06:53 Warning: Killed with signal 15 dovecot: Aug 03 08:07:10 Error: auth(default): ldap(seriv,127.0.0.1): No password in reply --- here is the snippet from apacheds debug log: --- message Id : 2 Search Request Base Object : 'ou=people,dc=parkheights,dc=dyndns,dc=org' Scope : whole subtree Deref Aliases : never Deref Aliases Size Limit : no limit Time Limit : no limit Types Only : false Filter : '(&(objectClass=posixAccount)(uid=seriv))' Attributes : gidNumber, uid, userPassword, homeDirectory, uidNumber baseDn : 'ou=people,dc=parkheights,dc=dyndns,dc=org' filter : '(& (objectClass=posixAccount) (uid=seriv) ) ' scope : whole subtree typesOnly : false no limit Time Limit : no limit Deref Aliases : never Deref Aliases attributes : 'gidNumber', 'uid', 'userPassword', 'homeDirectory', 'uidNumber' message Id : 2 Search Result Entry Object Name : 'uid=seriv,ou=people,dc=parkheights,dc=dyndns,dc=org' Attributes Attributes Attribute id : 'uid', Values : ['seriv'] Attribute id : 'gidnumber', Values : ['1927'] Attribute id : 'userpassword', Values : [0x7B 0x4D ...

[Dovecot] Sometimes Dovecot v1.0.3 does not accept new connections
by Steffen Kaiser 30 Oct '07

30 Oct '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, occasionally Dovecot stops to accept new connections. Already existing ones do function properly. Strace'ing dovecot-auth reveals that it is running and is authentificating users, the logfile logs new connections. However, lots of other connects just stall, before the IMAP server responds with the greeting. My user backend is a LDAP server. I've sniffed the interface, but I also don't see numerous connection attempts, so I suppose, that there is no DoS attack running. The logfile contains no warning or error except: dovecot: Oct 17 15:34:44 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:34:52 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:02 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:05 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:12 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:19 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:20 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:25 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:26 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:27 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:41 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:42 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:47 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:49 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:50 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:35:56 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 dovecot: Oct 17 15:36:03 Warning: auth(default): Growing pool 'plain_auth_request' with: 2048 Does somebody has an idea, where to go to look into the issue?

[Dovecot] 1.1Beta5 Issue
by Jeff Grossman 30 Oct '07

30 Oct '07

I installed 1.1Beta 5 this weekend. I had no problems at all yesterday using Thunderbird. I started reading my mail with Squirrelmail this morning and everything was going pretty smooth. I tried to delete a daily e-mail I receive from careerbuilder.com and the IMAP process shot up to 99.9% and I was not able to do anything in Squirrelmail. I killed that process and tried it again just to be sure what it was. And it did it again. I can delete any other message with no problems, just that one causes me issues. I am not sure if Thunderbird is the same, I will have to wait until I get home tonight. If there is any troubleshooting you would like me to do, please let me know. Jeff
