[Dovecot] Solaris NFS woes
by John Harper 18 Dec '06

18 Dec '06

I am using dovecot 1.0.rc15 (a similar problem occurred in rc10) on Solaris 9 (sparc). When working with a user who's home dir is on a local disk everything seems fine. But when that home is on an NFS-mounted disk things are very badly awry. Both the indices and the subscriptions file are being destroyed and what is left behind are files with names of the form .nfs72C034 etc. These files are described in the shell script nfsfind - every Solaris system ships with a root cron to run nfsfind and delete stale files: # These files are created by NFS clients when an open file # is removed. To preserve some semblance of Unix semantics # the client renames the file to a unique name so that the # file appears to have been removed from the directory, but # is still usable by the process that has the file open. I dont't see why dovecot would be unlink'ing it's active files while running - but I actually managed to see the dovecot.index.log appear briefly and then change to a .nfsXXXX file during the test user login. dovecot.index always seems to exist correctly but from local tests I know there should be a dovecot-uidlist, dovecot.index.cache, dovecot.index.log too, and these all appear to be .nfsXXXX files I can't seem to find anything relating to this specific problem in the archives, although these files have been mentioned a few times. And yes I do have mmap_disable = yes (but that is only relevant to the indexes, and the same thing is happening to the subscriptions file - ie some common library code for dealing with files has an issue) I should also note that these NFS mounts have been in existence for years and lots of things are running through them, so there shouldn't be anything wrong there. Suggestions, please?

[Dovecot] [PATCH] don't force read bit on base_dir
by Max Kellermann 18 Dec '06

18 Dec '06

Hi, I would like to disallow dovecot to read its base_dir (mode 0310). This is currently not possible, because settings_verify() in src/master/master-settings.c will "fix" the directory mode to 0750. The following patch for 1.0rc15 ignores the read bit (0444) when checking the directory permissions. Max

Re: [Dovecot] Problems with Mailstorage path.
by Raja T Nair 17 Dec '06

17 Dec '06

Hi, I have created symlinks to all the mail folders with caps in their name. but that does not solve the issue. If a user types in mixed case username( e.g. RtNaiR for rtnair ), dovecot creates a new mailfolder for that username; Is there a way to instruct dovecot not to create a mailbox and throw an error if the folder does not exist? raja.

[Dovecot] Proxy MD5/NTLM requests not working
by Cassidy B. Larson 16 Dec '06

16 Dec '06

Having some problems with setting up a proxy with any authentication mechanisms other than PLAIN. My passwords are stored in my database in plaintext (and MD5), so I figure I could use whatever scheme I want. Using the latest RC15. MySQL for the backend. This first one is CRAM-MD5. It fails (scheme_r != NULL??) then PLAIN tries to take over, but the auth server is restarting: Info: auth(default): client in: AUTH 1 CRAM-MD5 service=POP3 secured lip=204.x.x.x rip=209.x.x.x resp= Info: auth(default): client out: CONT 1 PDA1MTA2OTcxNzY0NjA1MTAuMTE2NjIwMjUxNkBtYXJiZWxsYS5pbmZvd2VzdC5jb20+ Info: auth(default): client in: CONT 1 YnV0Y2hAaW5mb3dlc3QuY29tIDBhNGNjNDJlN2QxOWI4ZjlkYjk0MjE2OTgxOGVmM2Ri Error: auth(default): file passdb-cache.c: line 120 (passdb_cache_lookup_credentials): assertion failed: (*scheme_r != NULL) Error: child 63406 (auth) killed with signal 6 Info: pop3-login: Authenticate PLAIN failed: Authentication failed: Authentication server isn't connected, try again later..: method=PLAIN, rip= 209.x.x.x, lip=204.x.x.x, TLS After this I tried adding this line to my Proxy dovecot-sql.conf file since the Destination already had it: default_pass_scheme = plain When I try connecting now, I get this: Info: auth(default): client in: AUTH 1 CRAM-MD5 service=POP3 secured lip=204.x.x.x rip=209.x.x.x resp= Info: auth(default): client out: CONT 1 PDg1NDgyMTgxOTgyNzI0NDIuMTE2NjIwMzg2MkBtYXJiZWxsYS5pbmZvd2VzdC5jb20+ Info: auth(default): client in: CONT 1 YnV0Y2hAaW5mb3dlc3QuY29tIDIzM2FjODE3NmMwNzZkNWE1MmZhNzdhNDJlODVmMjAy Info: auth-worker(default): sql(user(a)host.com,209.x.x.x): query: SELECT NULL AS password, v.storeIP AS host, v.userID AS destuser, 'Y ' AS nologin, 'Y' AS nodelay, 'Y' AS proxy FROM virtmailbox AS v WHERE v.userID = 'user(a)host.com' and v.imap_active = 1 Error: auth-worker(default): file passdb.c: line 120 (passdb_handle_credentials): assertion failed: (password != NULL) Error: child 69536 (auth-worker) killed with signal 6 Info: auth(default): client out: FAIL 1 user=user(a)host.com temp This last error is the same that I get when trying NTLM. Now, the password should be NULL, since I dont want to do any authentication on the Proxy, but simply forward it off to let the destination host handle it. Now the host that the proxy sends it off to works fine when I connect to it directly. I have the same default mechanisms allowed on both Proxy and destination. Anybody have any clues? I'd really like to figure out how to proxy "secure password" requests to my destination server without having to rely on plaintext. Plaintext works fine with the proxy, but I am unable to get anything else working. Am I overlooking something obvious? Thanks, Cassidy

[Dovecot] Trash and quota
by Kenny Dail 16 Dec '06

16 Dec '06

I can't seem to find the magic combination to get dovecot to ignore the trash folder when counting quota. I've got 1.0rc15 and using maildir quotas. Not being able to trash messages when over quota is quite annoying. the docs suggest the following: plugin { quota = maildir:storage=10240:ignore=Trash } but as my quotas are defined per user via mysql DB, I'm thinking that I need a modified version such as: plugin { quota = maildir:ignore=Trash } Which does not work. just in case it's a semantic problem, I also tried: plugin { quota = maildir:ignore=INBOX.Trash } which also doesn't work. I need other ideas of what to try to make it work if you please. -- Kenny Dail <kend(a)amigo.net>

[Dovecot] considering dovecot
by Rick Hazey 15 Dec '06

15 Dec '06

Hi all. I'm making a case to use Dovecot over Courier and would like some feedback. I've searched the web extensively and have been unable to find any hard information regarding Dovecot's IMAP performance. I've got some pressure to use Courier but my gut tells me that Dovecot should be much faster. In particular, I will have typical users with mailboxes exceeding 10,000 emails and in some cases up to 100,000. Courier might be the "safe" choice but I'm not confident it can handle inboxes with that many messages. Dovecot, with its indexes, should be much, much faster. Can anyone point me to some benchmarks or production uses of dovecot that bear this out? From my research, Courier maildrop appears to be what I need for local delivery. Is it possible to use Maildrop for local delivery with Dovecot? Or is the Dovecot LDA needed to update the maildir indexes? I also need the capability for users to set their own vacation messages via a web page. Maildrop looks to handle this easily (by allowing me to link the maildrop filter to a file with the vacation message) but I don't see similar capability with the Sieve plugin. I do see where I can create a vacation message with Sieve but the text of the message seems to be required to reside within the Sieve script. Perhaps I'm missing something? Any feedback would be greatly appreciated.

[Dovecot] problem on "multiple addresses"
by Quentin Chung (KTS) 15 Dec '06

15 Dec '06

I have do a search on google but found nothing.. My configuration is: RH ES3 Dovecot 1.0.0.4 from atrpms (dovecot-1.0-0_4_stable20050221.el3.at) My problem is.. my mailbox has 2 internet (interface A, ip 1.2.3.4 and interface B, 9.8.7.6) and 1 intranet (interface C, 192.168.0.x) access. Default route is on interface A. pop3/imap access from connection A & C has no problem at all. But, any connection from interface B it will get a timeout error. I can sure routing is correct.. since I have virtual host on web server and running ftp server, I tested it connecting from both IP it shows no error.. Anyone can give me some hints to fix it ?? thanks in advance.

[Dovecot] dovecot's LDA agent
by Bartosz Giza 15 Dec '06

15 Dec '06

Hi! I am using courier IMAP with maildrop as LDA. I started reading about dovecot and i like started to feel that i can switch to it. I have couple questions mostly about dovecot's LDA. My main problem with maildrop is that i have to create manualy user directories grr. All my domains are set up as virtual with postfix. So when i add new accout thru my web panel and i have to create user dir manually. This is really annoying thing. Maildrop checks if there is user dir before delivering mail. If not it report error. I want to know if dovecot's LDA create automaticly user dirs or not. I need also filtering language in LDA and i kknow that LDA has option to use sieve scrips. Generaly i am not sure that dovecot will be a good choice to switch from courier. Could anybody help me ? -- best regards, Bartosz Giza

[Dovecot] Shared folder subscriptions
by Nagy László 15 Dec '06

15 Dec '06

Hello! I have this shared folder: namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } It is accessible for all users in a specific group (mode 770, umask 0007). Users in that group should always be subscribed to all subfolders, so I did not use a different CONTROL for each user. All of our IMAP users were in that group, until now. I added a new user and she should not be able to access the public folder. She is not in the right group, so everything is okay, except that her e-mail client TRIES to open Public. It is because she is also subscribed to that folder. My question is: is it possible to have different control files for different groups of users? Having a different control file for each user would not be good for me, it would cause lot trouble. Having the same control file for all users is also bad, I would get many complaints because error messages would show up. In the worst case I can write a script that automatically subscribes everybody to the correct folders, but this would be very clumsy. Any ideas? Thanks, Laszlo

[Dovecot] Actually what is the SQL DB used for?

14 Dec '06

Is a RDBMS required for Dovecot to run in small (SOHO) environments? (Does it store indexes to the mail, etc.?) Or is it strictly leveraged for larger-scale environments? I'm asking, because the INSTALL says ./configure and make is enough for most...but as my previous post requested...there isn't anywhere that lists Required Packages/Software. We need to get that out there before 1.0RC becomes 1.0! :) -AJ

[Dovecot] Slightly off topic question but ...
by Marc Perkel 13 Dec '06

13 Dec '06

I'm using files for passwords that look like the unix passwd and shadow files, except each domain has it's own pair of shadow and password files for that domain. And dovecot works fine with that. So - here's my off topic question. I'm trying to create a PHP interface to allow user to change their password in these passwd / shadow file combos. What kind of encryption do they use and specifically what PHP command would I use to encrypt a password like the shadow file has? Thanks in advance.

[Dovecot] Recipient delimiters, deliver and SQL databases
by Nils Vogels 13 Dec '06

13 Dec '06

Hi! As a new user, I'm trying to set up a postfix + dovecot combination, and so far all is running smoothly. I'm using the guidelines that came with postfix and adjusting them as I go. My user and alias database is stored in MySQL, using the scheme from 'PostfixAdmin' (http://high5.net/page9.html) and I am using the dovecot LDA 'deliver' to drop messages into mailboxes that exist solely as virtual users. Users can login using both pop3 and imap, and retrieve the e-mails sent directly to them, so I'm happy with that. One of the features supported by postfix, and required for my setup is recipient delimiters. Using recipient delimiters, you can basically send extra information in the e-mail address, to maybe deliver the message into subfolders directly, or to run anti-spam software such as TMDA against. When I try to deliver such a message, I get a user unknown: Dec 9 14:25:01 vm-mail postfix/pickup[91477]: 4574A6420: uid=0 from=<root> Dec 9 14:25:01 vm-mail postfix/cleanup[91487]: 4574A6420: message-id=<20061209142501.4574A6420(a)vm-mail.mydomain> Dec 9 14:25:01 vm-mail postfix/qmgr[91478]: 4574A6420: from=<root(a)vm-mail.mydomain>, size=290, nrcpt=1 (queue active) Dec 9 14:25:01 vm-mail dovecot: auth(default): master in: USER 1 user+test@mydomain service=deliver Dec 9 14:25:01 vm-mail dovecot: auth-worker(default): sql(user+test@mydomain): SELECT maildir, 143 AS uid, 143 AS gid FROM mailbox WHERE username = 'user+test@mydomain' AND active = '1' Dec 9 14:25:01 vm-mail dovecot: auth-worker(default): sql(user+test@mydomain): User not found Dec 9 14:25:01 vm-mail dovecot: auth(default): master out: NOTFOUND 1 Dec 9 14:25:01 vm-mail postfix/pipe[91489]: 4574A6420: to=<user+test@mydomain>, relay=dovecot, delay=0.14, delays=0.07/0.03/0/0.04, dsn=5.1.1, status=bounced (user unknown) Relevant snippets from postfix's master.cf: # Dovecot LDA dovecot unix - n n - - pipe flags=DRhu user=dovecot:dovecot argv=/usr/local/libexec/dovecot/deliver -d ${recipient} and postfix's main.cf: virtual_gid_maps = static:143 virtual_mailbox_base = /mail/virtual virtual_minimum_uid = 125 dovecot_destination_recipient_limit = 1 virtual_transport = dovecot virtual_uid_maps = static:143 and dovecot's dovecot.conf: protocol lda { postmaster_address = postmaster@mydomain sendmail_path = /usr/sbin/sendmail auth_socket_path = /var/run/dovecot-auth-master } auth default { passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb sql { args = /usr/local/etc/dovecot-mysql.conf } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } master { path = /var/run/dovecot-auth-master mode = 0600 user = dovecot group = dovecot } } } And offcourse dovecot-mysql.conf: # Database driver: mysql, pgsql driver = mysql # Currently supported schemes include PLAIN, PLAIN-MD5, DIGEST-MD5, and CRYPT. default_pass_scheme = CRYPT # Database options connect = host=myhost dbname=mydb user=myuser password=mypass password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT maildir, 143 AS uid, 143 AS gid FROM mailbox WHERE username = '%u' AND active = '1' #EOF Now, I am pretty sure the problem lies with the %u, expanding to user+test@mydomain, which in some way should become user@mydomain, since the latter is the actual mailbox name of the user, but: how?

[Dovecot] dovecot imap mbox multiple connections
by Danni Allen 12 Dec '06

12 Dec '06

Hi, The company that I work for are currently looking at a changeover in clients from pegasus mail(v4) to Thunderbird (v1.5.0.8). We run dovecot (v 0.99.13) with mbox. We currently have a bunch of shared folders sitting in a dummy imap account that they all connect to and view. I have read that problems with Thunderbird have been encountered with this setup due to multiple connections to the account and that a possible solution is to convert from mbox to maildir. I was simply wondering if anyone knows anything about this, as I don't seem to be able to find any information on it other than a single thread with a single comment with what seems like anecdotal evidence rather than something acknowledged. Is there a problem with this? Rgds, Danni Allen
