[Dovecot] imap process uid mapping question

Hi all. I'm new to dovecot. I promise I've looked over the docs and lists for an answer to this, but I didn't find anything. If I missed something I apologize. I'm running dovecot 1.0.beta2 on debian testing. It's almost working, I'm getting permissions errors when the imap server actually goes to read the messages out of the cur Maildir directory.

[Dovecot] dovecot-dspam-plugin not launching dspam
by Stefan Schmidt 13 Apr '06

13 Apr '06

hello, i added the dovecot-dspam-plugin [1] to my dovecot-installation. when trying to move a mail out of or into the predefined spamfolder with thunderbird a messagebox shows : "dspam failed" and the message remains in its original position. i am using virtual mail users contained in a postgresql-database [2]. normal imap access and dspam training from the commandline works fine. a posting concerning probably the same issue has been posted on the dspam-mailinglist [3], but there haven't been any helpful replies so far. furthermore i suspect the plugin is missing the --user option when calling dspam, since this seems to be mandatory [4,5], but unfortunately adding this option in the plugin doesn't change its behavior. i am working on a debian system and currently using dovecot 1.0.beta3-3, dspam 3.6.4-2+b1 and the dspam-plugin "for dovecot beta 2 and 3". 1) calling dspam from the commandline with the same parameters as in the (slightly modified) plugin works fine :/# su virtual :/$ /usr/bin/dspam --user retrain --source=error --stdout --class=spam --signature=4,4434846e237406491211187 --debug -> /var/log/dspam.debug No QuarantineAgent option found.

[Dovecot] Dovecot-LDA & permissions
by Duncan Hutty 12 Apr '06

12 Apr '06

I set up postfix/dovecot with the dovecot-LDA according to the dovecot wiki, in particular: http://wiki.dovecot.org/LDA#head-dacb9b9a1f19c3ea86bb6f8caa3d64e3ddad9ef8 For separation of privileges, I want to have one uid per virtual domain rather than have the vmail user own all directories under the mailstore. Therefore the LDA, deliver, in order to deliver must fulfill one of the following: a) it must be started as root b) it must be setuid c) it must have write access to the user's mailstore even as an unprivileged user itself. But a) postfix declines to this: postfix/pipe[26267]: fatal: user= command-line attribute specifies root privileges which is probably a good thing. b) will work, but I'm really wary of making anything setuid c) could be done if the group that deliver runs as (as defined in the user= attribute in master.cf) is the same as the group of each mailstore directory and that this group has write permissions *and* the sticky bit of each mailstore directory is set so that the file created by deliver is owned by the uid of the mailstore owner not deliver's uid. This is not exactly a question as such because I believe, subject to a little testing, that I have a working mail setup. However, I believe in doing things the right way wherever possible and I'm sure someone must have come across this before, so I'm submitting to the list inviting comment. How are most of you doing this? Are you just using a single uid for all virtual users? -- Duncan Hutty System Administrator, ECE Carnegie Mellon University Please use informative subject lines

[Dovecot] password length
by Mark Richards 12 Apr '06

12 Apr '06

After setting up a very sweet Dovecot installation (with OpenLDAP) we're finding something strange: passwords are accepted but only the first 8 characters and anything less than 8 characters is an invalid password For several reasons, including allowing longer passwords to make them more difficult to crack, I'd rather be able to use longer passwords. LDAP seems to have attributes for minimum and maximum password lengths. Ours is set currently at 256 char maximum. So my guess is that Dovecot may be doing something, or there's a configuration item I missed. Checked all the docs and the wiki. Anyone? Mark Richards

[Dovecot] strip domains

Hello, Running FC5 x86_64 with dovecot-1.0-0_8.beta3.rhfc5.at Using system user/passwds for 99.99% of users...have sql user/pass enabled to test virtual users from mysql. How do I strip off the domain when users provide user(a)domain.com so that my userdb and passdb use just 'user'? (disregarding sql auth...I'm not concerned with that right now). My dovecot.conf auth config: passdb pam { args = dovecot } passdb sql { args = /etc/dovecot-sql.conf } userdb passwd { } userdb sql { args = /etc/dovecot-sql.conf } Can I just pass userdb the 'user' using an args= statement? %d? ...and then also to the passdb?

So if I understand this correctly, %u matches the whole username in the sql database, but %n only matches the name before @? One thing we discovered in migrating from courier-imap to Dovecot is that courier-imap supported user@domain as a valid login name, where by default using %u in the SQL query, Dovecot does not. So it would have been useful for us to avoid a number of tech support calls for users who have user@domain configured in their mail clients. -- Roger J.

[Dovecot] Full text search indexing
by Timo Sirainen 12 Apr '06

12 Apr '06

SEARCH is probably the slowest command that Dovecot has, especially when searching texts from message bodies. There exists a lot of text search engines, but unfortunately as far as I know there exists only one that can be used with IMAP. The reason why IMAP is special is because it requires that when searching eg. "ello", it must match also mails which contain eg. word "hello". Most search engines support only matching either complete words or matching from the beginning of the words. So, the one usable engine which I know of is Cyrus's squat indexing. It works basically by indexing the mails in 4 byte blocks and storing them in a trie. So if there exists a string "he llo", it indexes "he l", "e ll" and " llo" strings. When searching it then gets the first 4 bytes of the search keyword, looks them up from the squat index and then once it gets a list of matched mails, it reads the mails and does a proper search for only them. So the squat index doesn't give exact results, but only narrows down the number of mails which have to be searched. The biggest problem with those squat indexes is that it doesn't support incremental updates, so there has to be some nightly runs to rebuild the indexes from scratch. And with lots of users that's not practical, so I think that's the reason why the squat indexes aren't all that commonly used with Cyrus. I was thinking about taking the basic ideas from the Cyrus squat indexer but making it possible to update it incrementally so Dovecot could do it automatically. Also to reduce space I was thinking about sorting the 4 byte strings so instead of eg. "abcd", "dcba" and "abdc" all being indexed, they could all be stored as "abcd" (so the search key would also have to be sorted before use). But that might cause larger result sets making the search slower, so I'll have to test if it's worth it. Unicode characters might also be a problem. If the characters are stored in 16bit characters, it would waste space. If they're stored in UTF-8 the 4 bytes might not be enough to give a useful index (as a single character might take even 5 bytes). One thing I was thinking was to not index in 4 byte blocks, but 4 character blocks in UTF-8, so the trie could be 4..20 levels deep depending on what unicode characters are used (in finnish text it would probably be max. 7 levels deep). So, now would be a good time to tell if you can think of some better ideas how to do this, especially if you know about some new algorithms specifically designed for this kind of searching. :) Pretty much all the algorithms I've found about this were suffix trees/arrays and this basic trie thing.

I'm not asking for every new feature, just one that I think fits in with the current design of dovecot already and is a standard feature provided by other servers.

[Dovecot] [patch] MD5 variable modifier
by Ben Winslow 12 Apr '06

12 Apr '06

Hello, I've taken a different (better) approach to getting tpop3d-compatible UIDLs: the first attached patch (...md5_modifier.diff) adds a variable expansion modifier (%M) to return the md5sum of the expanded variable in hex. With the patch, you can get tpop3d-compatible UIDLs by setting pop3_uidl_format to %Mf. While testing interactions with other modifiers (e.g. %MUf to get the md5sum in uppercase), I noticed that %U is broken -- it lowercases the input just as %L does. The second patch (...ucase_modifier_fix.diff) is a one-liner to fix that. Finally, the third attached patch (...apop_aesthetics.diff) is another trivial patch to add a space between the server greeting and the APOP challenge. I think it looks better when telnetting to the server to diagnose something, and since spaces are stripped from the end of the login_greeting, editing the code is the only way to add the space. Cheers, -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] Postfix dovecot SASL and LDAP not working...
by Brice Figureau 12 Apr '06

Hi, I'm trying to setup a new mail server where postfix 2.3-20060405 would use Dovecot's SASL and users located in LDAP. It's with dovecot-1.0-beta5. On the postfix side, I followed the SASL_README and have the following in main.cf: smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes On the dovecot side I have the following related to auth: auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain digest-md5 cram-md5 # LDAP database passdb ldap { # Path for LDAP configuration file, see /etc/dovecot/dovecot-ldap.conf for # example args = /etc/dovecot/dovecot-ldap.conf } # LDAP database userdb ldap { # Path for LDAP configuration file, see /etc/dovecot/dovecot-ldap.conf for # example args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } user = root ## ## dovecot-lda & postfix SASL specific settings ## socket listen { master { path = /var/run/dovecot-auth-master mode = 0666 } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } pop or imap authentification with LDAP works fine: Apr 11 17:43:08 localhost dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=IMAP^Isecured^Ilip=127.0.0.1^Irip=127.0.0.1^Iresp=AGJyaWNlAHRvdG8= Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): base=ou=people, dc=daysofwonder, dc=com scope=subtree filter=(&(objectClass=CourierMailAccount)(uid=raymond)) fields=uid,userPassword,homeDirectory,uidNumber,gidNumber,mailbox Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): uid(user)=raymond userPassword(password)={PLAIN}toto homeDirectory(userdb_home)=/home/raymond uidNumber(userdb_uid)=1000 gidNumber(userdb_gid)=1000 mailbox(userdb_mail)=/home/raymond/Maildir Apr 11 17:43:08 localhost dovecot: auth(default): client out: OK^I1^Iuser=raymond^I Apr 11 17:43:08 localhost dovecot: auth(default): master in: REQUEST^I1^I15439^I1 Apr 11 17:43:08 localhost dovecot: auth(default): ldap(raymond,127.0.0.1): base=ou=people, dc=daysofwonder, dc=com scope=subtree filter=(&(objectClass=CourierMailAccount)(uid=raymond)) fields=homeDirectory,uidNumber,gidNumber,uid,mailbox Apr 11 17:43:08 localhost dovecot: auth(default): master out: USER^I1^Iraymond^Isystem_user=raymond^Ihome=/home/raymond^Iuid=1000^Igid=1000^Imail=/home/raymond/Maildir Apr 11 17:43:08 localhost dovecot: imap-login: Login: user=<raymond>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured postfix SASL doesn't work, but more important don't print any debug messages, nor try to contact the LDAP server at all: Apr 11 18:00:59 localhost postfix/smtpd[15637]: connect from localhost.localdomain[127.0.0.1] Apr 11 18:01:13 localhost dovecot: auth(default): client in: AUTH^I3^Iplain^Iservice=smtp^Iresp=YnJpY2UAYnJpY2UAdG90bw== Apr 11 18:01:14 localhost dovecot: auth(default): client out: FAIL^I3^Iuser=raymond Apr 11 18:01:14 localhost postfix/smtpd[15637]: warning: localhost.localdomain[127.0.0.1]: SASL plain authentication failed: I tried several variations of the config, like without userdb prefetch, moving postfix socket config block in another auth block... Nothing worked. Since the samples are mentioning only pam as userdb and passdb source, maybe it can't work with LDAP ? Any idea on how to solve this issue ? Thanks, Regards, -- Brice Figureau

[Dovecot] DON'T DELETE THIS MESSAGE?
by Knute Johnson 12 Apr '06

12 Apr '06

I have a new install of FC5 running dovecot 1.0.0 beta 2.7. I get my mail with POP3 but I have a user using IMAP. They both work great but I keep getting a message from dovecot in my mail saying DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA. I think it is there to help keep track of IMAP messages. Since I use POP3 is there any way not to have it show up all the time? I've deleted it, I've deleted my account and re-added it but it keeps coming back. Dovecot is also making a 'mail' directory in my ~ that I don't think I need. What can I do about this? Thanks, -- Knute Johnson Molon Labe...

[Dovecot] IMAPS - timeout while moving mails
by Petar Bogdanovic 12 Apr '06

12 Apr '06

Hi, I'm using Dovecot v1.0.beta5 (NetBSD 3.0, i386) and Mozilla Thunderbird 1.5 (XP, i386). My dovecot.conf is pretty simple, because I just use dovecot for me as the only user. However, when I try to move a 'larger' amount of mails (>200) from my local TB-mbox to the remote IMAPS-storage, the process hangs after about 150 - 160 transferred mails (the 'blocking' mail is _never_ the same). I don't have the slightest clue why - there is nothing in the logs - even if I turn 'verbose_ssl' on. After a while, TB tells me, that the server timed out and dovecot says: "imap(petar): Disconnected" Usually - if I close my MUA correctly - dovecot says: "imap(petar): Disconnected: Logged out" Is somebody maybe experiencing something similar? Thank you very much & with kind regards, Petar Bogdanovic
