[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.

Theirs is a proprietary system which from what I've read, seems to use SMS in combination with IMAP. Wacky. (If you aren't talking about iPhone compatibility, I'm less knowledgeable, but dovecot does support IDLE-style "imap push" style notification.) Alan Ferrency

[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 31 Oct '07

31 Oct '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!"

[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 29 Oct '07

29 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

Thanks for the quick fix. Jeff

[Dovecot] time going back
by zbigniew szalbot 29 Oct '07

29 Oct '07

Hi all, Sorry if this is trivial. I am just concerned. In Poland we will be putting the clocks one hour behind (back) on Sunday. I once saw dovecot killing itself because I manually adjusted the clock in the past. Will it not happen in this case? Thanks for your ideas. Zbigniew Szalbot
