[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] Error in Thunderbird

I received a mail, Thunderbird was supposed to move that mail in a folder, according to its filter rules, but appeared this popup: http://luigi.rosa.name/dovecot1.gif The log entries are: Dec 14 07:23:07 mail dovecot: IMAP(lrosa): Fixed index file /var/spool/mail2/lrosa/.HT list/dovecot.index: first_recent_uid_lowwater 839 -> 838 Dec 14 07:23:07 mail dovecot: IMAP(lrosa): Corrupted index file /var/spool/mail2/lrosa/.HT list/dovecot.index: Duplicate header extension keywords The file http://luigi.rosa.name/dovecot1.tgz contains the dovecot files I found in the folder "HT list" (no problem about privacy: the archives of that mailing list are public).

[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?
by Aaron J Weber 14 Dec '06

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

[Dovecot] 'NO' 'Unknown error'
by Nagy László 11 Dec '06

11 Dec '06

Dear List, I'm writting a program in Python that connects to a dovecot server and copies/moves messages across different shared folders. The program throws an error while executing this IMAP command: UID COPY 232 Archive/Notifications The same program works fine with other directories and messages. This is the response from the dovecot server: ('NO', ['Unknown error']) Do you have an idea what is the problem? This error message is very cryptic, it does not tell anythig about what is causing the problem and how to fix it. By the way, I'm using dovecot-1.0.r7_2 on FreeBSD 6.1-RELEASE. I cannot upgrade to a newer - I had to downgrade to r7 before because dovecot did not find the inboxes of my POP3s users. (But it did find the same inboxes for my IMAPs users.) Thanks, Laszlo

[Dovecot] Using custom Maildir subfolders with pop3 deliveri
by Bojan Popovic 11 Dec '06

11 Dec '06

Greetings, I am trying to make my antispam protection on user basis. So I need something like .junkmail folder in every user maildir. But the problem I am having is that my mail client can not download mail put in .junkmail folder. I am usin POP3 only, Maildir mailboxes (default_mail_env = maildir:/var/mail/%u) and whether I make folder with leadin dot or not it is never shown in mail client. Sincerely I don`t even know if it is posible with POP3, but it would be very hard converting to IMAP at this moment. Thanks in advance.

[Dovecot] Problems with Mailstorage path.
by Raja T Nair 11 Dec '06

11 Dec '06

Hi all, my environment: dovecot-1.0.rc15 Fedora Directory Server 1.0.2 Currently I've configured dovecote to find user's mail folder like this: dovecot.conf mail_location = maildir:/var/vmail/%d/%u/Maildir All my domain mailboxes are under /var/vmail, as evident. But there are some users whose mail folders are directly under /var/vmail like this one: /var/vmail/myuser1(a)mydomain1.com also, some have their folder names starting with caps like: /var/vmai/mudomain1.com/Myuser1(a)mydomain1.com This creates problems when these users try to login. Here I want dovecote to kind of assemble the mail storage path from mailMessageStore ldap attribute of the particular user. i.e, dovecot should add the mailMessageStore attribute's value to /var/vmail. Can somebody help me in solving this issue? regards, raja. -- +91 944 715 5548(Cell)

[Dovecot] Huge IMAP folder takes forever
by Peter Lindgren 10 Dec '06

10 Dec '06

Hi! Just updated to 1.0 rc15, but the problem remains. I think it could be client-dependent to some extent. I have only IMAPS access and Maildir. I have one mailbox which contains some 10,200 mails. That mailbox takes forever (have waited 30 minutes and then aborted) to open with Thunderbird 1.5.0.7. Other mailboxes (like dovecot :-), only 6984 mails) opens quickly. When Thunderbird tries to open this folder, the imap process on the server uses roughly all cpu resources. There isn't much disk I/O, at least as far as I can tell by listening at the server. The dovecot is upgraded from 0.99.something. Should I remove index files first, and in that case which? Is there something cached in Thunderbird? Here's the directory listing for the troublesome folder: -rw------- 1 peter peter 28 Jan 7 2006 .customflags -rw------- 1 peter peter 49248 Feb 7 2006 .imap.index -rw------- 1 peter peter 420998 Feb 7 2006 .imap.index.data -rw------- 1 peter peter 10256 Feb 7 2006 .imap.index.log -rw------- 1 peter peter 49200 Feb 7 2006 .imap.index.tree drwx------ 2 peter peter 686592 Dec 10 15:06 cur -rw------- 1 peter peter 64 Jun 6 2006 dovecot-keywords -rw------- 1 peter peter 619832 Dec 10 15:04 dovecot-uidlist -rw------- 1 peter peter 162992 Dec 10 15:21 dovecot.index -rw------- 1 peter peter 8826880 Dec 9 15:36 dovecot.index.cache -rw------- 1 peter peter 33776 Dec 10 15:22 dovecot.index.log -rw------- 1 peter peter 193660 Dec 3 12:50 dovecot.index.log.2 drwx------ 2 peter peter 512 Dec 10 15:06 new drwx------ 2 peter peter 512 Dec 10 15:04 tmp Thanks in advance, Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] Configuring for virtual users
by Gerard Seibert 10 Dec '06

10 Dec '06

I haven't tried this yet; however, I would like to know if it would work. Using Postfix, I am setting up numerous virtual users. These users obviously do not have an account on the mail server. I have created a "domain.net" account. Assuming that Postfix is properly set up to deliver to the specified accounts, which will be held under the "domain.net" directory, will this work in the dovecot.conf file: # default_mail_env = maildir:/var/mail/%d/%u or do I need to modify it somehow? -- Gerard

[Dovecot] Full text search indexing
by Timo Sirainen 10 Dec '06

10 Dec '06

There are now two full text search backends in CVS HEAD: - squat: My own full text search index based on ideas from Cyrus Squat indexes. Supports substring searches. - lucene: Uses CLucene library. It should be pretty easy to add support for more backends. As I've explained a couple of times already, IMAP RFC says that searches are done by matching substrings, so the Lucene backend isn't fully RFC compliant. Currently it's anyway used to optimize standard SEARCH BODY/TEXT rules, but I'll probably make it optional and instead add new X-NONEXACT-BODY/TEXT rules. Then it will be possible to use both Lucene and Squat backends to optimize different searches (eg. Lucene for your modified webmail and Squat for standard IMAP clients). The Squat index finally worked better than I thought. It has two limitations: - Search strings must be at least 4 characters long - Those 4 characters can't contain spaces So eg. searching for "ip add" doesn't work, but "ip addr" does. By "doesn't work" I mean it fallbacks to the slow old way of going through all the mails. The space limitation exists only because I thought that such searches are going to be rare, and this reduces the index size by 20-50%. So the Squat indexing works by looking at 4 character blocks. So when searching for "address": - Get a list of UIDs for "ress" - Filter out UIDs which don't appear for "dres" - The same for "ddre" and "addr" - Open all the messages that are left in the UID list and drop out the messages where the whole "address" word doesn't exist. I think searching the words backwards usually finds fewer hits and makes the search faster. As for the index sizes, indexing my dovecot mbox with 7495 messages and size of 32479980 bytes it produced: dovecot.index.search : 2166526 bytes dovecot.index.search.uids : 6074155 bytes So that's about 25% of the mailbox size. Last I checked, Cyrus Squat took about 120% (with different messages). Anyway as you can see the uids file is larger than the search trie file, so the number of messages is more important in determining the index size than the number of bytes. The initial index build is pretty slow, but adding new messages to the existing index should be pretty fast. The new messages aren't indexed until client does a SEARCH BODY/TEXT. I'm not sure if the messages should be optionally indexed immediately as they're seen (or even added by Dovecot LDA). Oh and another difference to Cyrus Squat is that Dovecot's version indexes 16bit characters and not bytes. So non-English messages get indexed much more nicely. If you want to try this yourself, you'll need to add: protocol imap { .. mail_plugins = fts fts_squat } plugin { fts = squat }

In the > mean time this user is trying to establish pop3 on a 24/7 basis $-) If you are not selective on which users get the message (i.e. you want this notice to go out to all POP users), then you can do what the previous poster said and make a read-only mailbox and redirect the user's INBOX to this file (via symlinks, or dovecot.conf or what-have-you). This is probably the easier route. Another easy solution might to use tcp-wrappers and reply to all connections to port 110 with -ERR Please contact ... Some (most?) mail readers will pop this message to the user. Another solution which I employed (for another reason) is to make your own mini-dameon which enters into a fake POP session. Just allow any authentication information and server up your fake notice. The POP3 protocol is fairly simple and you only have to implement a small subset of commands: user(noop), pass(noop), list, stat, retr, top, rset(noop), noop(noop), dele(noop), quit. I return a "OK" for most of these commands and most of them are noops. I wrote a patch for qpopper to do this but you could probably modify the source to make it a stand-alone server: http://www.math.ubc.ca/~tam/Software/Qpopper.M2W/m2w.patch For the curious, the reason why I had to make this bizarre patch: http://www.math.ubc.ca/~tam/Software/Qpopper.M2W/ Joseph Tam <tam(a)math.ubc.ca>

Or, you can block the particular user at the firewall. Or if you have a special someone who is allowed POP3 you can give them an alternate port to login with, and not listen at all on port 110 if it really bothers you. -- Kenny Dail <kend(a)amigo.net>
