[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.

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?
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

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.

[Dovecot] Problems with Mailstorage path.

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

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>

[Dovecot] specifying INBOX with maildir for mail_location
by Post Master 08 Dec '06

08 Dec '06

I'd like to store all of my mail in maildir, but I want to store the inbox and indices on fast storage and everything else on deep storage. Does the following configuration value for mail_location accomplish this? mail_location = maildir:/data/deep/%Ld/mail/%Ln:INBOX=/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln ------------------------------------------------------------------------ If not, does the following configuration accomplish this with namespaces? mail_location = maildir:/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln namespace private { separator = / inbox = yes hidden = yes prefix = location = } namespace private { separator = / hidden = yes prefix = ??? location = maildir:/data/deep/%Ld/mail/%Ln/??? } ------------------------------------------------------------------------ Actually, I can't quite finish the namespace configuration. I'd like to set something like: prefix = * location = maildir:/data/deep/%Ld/mail/%Ln But I suspect the '*' won't actually match everything, and even if it did, I suppose it would also match the inbox. I began with listing any and every typical folder in its own namespace like: namespace private { separator = / hidden = yes prefix = drafts location = maildir:/data/deep/%Ld/mail/%Ln/drafts } namespace private { separator = / hidden = yes prefix = templates location = maildir:/data/deep/%Ld/mail/%Ln/templates } namespace private { separator = / hidden = yes prefix = sent location = maildir:/data/deep/%Ld/mail/%Ln/sent } and so on, but that doesn't seem very elegant. Also, namespaces scare me for client compatibility. Am I missing something obvious?

[Dovecot] Extra inbox problem
by Stephen Allen 07 Dec '06

07 Dec '06

One of my users (who uses Outlook) has lost all her folders that were inside her INBOX. She collects her mail by IMAP. I have confirmed that she has no folders in her INBOX. However, if I use Pine, I can see a couple of extra folders, "INBOX." and "Junk Email." that I don't think should be there. There already folders by that name but without the dot on the end. If I look in "INBOX." I can see the folders she's missing and the folder that they contain etc. I backed up and moved the files listed under .maildir, and Dovecot recreated them, but it made no difference to the problem. I don't understand why those extra folders appear in Pine, but not Outlook. Kind regards, Steve

[Dovecot] rc15 dumped core
by Hans Morten Kind 07 Dec '06

07 Dec '06

We have been running rc15 since Sunday experiencing no trouble, but today one user crashed. rc15 on Solaris-5.9, the server had app 6GB free memory at the time of the crash, app 70% idle running with an avg.load at 4 of 8 processors available. The USER's INBOX was quite smooth, app 13MB containing 320 messages. The core dump was accompanied with these log-entries: Nov 23 2006 12:27:00 [local3.error] IMAP(USER): Corrupted index cache file imapindex/USER/.imap/INBOX/dovecot.index.cache: invalid field header size 12:28:23 [local3.error] IMAP(USER): mremap_anon(1164206080) failed: Not enough space 12:28:23 [local3.error] IMAP(USER): mremap_anon(8192) failed: Invalid argument 12:28:24 [local3.error] child 17510 (imap) killed with signal 10 12:28:25 [local3.info] imap-login: Login: user=<USER>, method=PLAIN, rip=000.177.00.21, pid=19178 We have been observing a few of the 'invalid field header size' messages while running rc15. But as this USER, others seem to recover after the message has been logged. The messages from 'mremap_anon' have never been seen before. Actually '1164206080' looks very much like a timestamp, differing 75223 seconds from the time of the crash ... spooky I will start running the supplied code for memory debugging on this user and I enclose a back trace from the crash. The interessting stuff from the back trace is probably that hdr (and so cache->hdr) is 0xffffffff so that hdr->continued_record_count gives no sense (Cannot access memory at address 0xb) but cache->index->map->records_count is 320 Still on this and another server running rc15 (Sol5.8), we have thousands of happy users beeing served very fast by Dovecot. hmk

[Dovecot] rc15 sort bug

Hi, ive come across what looks like a bug in how dovecot sorts the mail when sorting on subject. We noticed this on our current beta8 version, and I can also reproduce it in rc15. One of our customers has hundreds of emails with subjects like this: Subject: 20060823 Kanglaonline-NSCN(IM) cadres violating Tml truce: NSCN(K) Subject: 20060824 LSE - Shell jv denies 3.2 bln usd fraud claims by Nigerian parliament Subject: =?iso-8859-1?Q?20060824_Ibinda_-_Onze_militares_angolanos_mortos_em_comba?= Subject: =?iso-8859-1?Q?20060824_Gingaocultural=2C_VoA_-_Deputados_constatam_clima?= Some of the Subject lines are encoded, some arent.

[Dovecot] Pre-rev1 compatibility

What about adding some compatibility for pre-rev1 IMAP4 clients which are still around (e.g., CDE dtmail, even in Solaris 10)? Especially, the understanding of command FETCH message (... RFC822.HEADER.LINES (parameters)) instead of FETCH message (... BODY.PEEK[HEADER.FIELDS (parameters)]) (with correspondingly changed replies) would be desirable and shouldn't be too difficult to implement.

[Dovecot] quota question
by Kenny Dail 06 Dec '06

06 Dec '06

I'm afraid I'm being a little confused by the whole quota setup with dovecot. I see references to quotas about, but I'm not certain how many of them apply to 1.0rc15. I currently have the conf setup as indicated on http://wiki.dovecot.org/Quota So, in my setup, I'm using Postfix, Maildrop and Dovecot. Mailstore is on NFS. Dovecot is handling the pop3 and imap connects. There seems to be some trouble in the quotas because Courier counts quota one way and Dovecot in a different way. Quotas are stored on a per user basis in the MySQL DB. The trouble I'm getting is that very frequently the quota being reported is quite different from reality. This leads to erroneous over quota delivery errors. So what is necessary to make sure the quotas work as they are supposed to in my environment? Once again thank you very much for your help. -- Kenny Dail <kend(a)amigo.net>

Or is customization only possible by modifying the source ? Regards __________________________________________ Dean Manners

[Dovecot] maildirsize update error
by Maykel Moya 04 Dec '06

04 Dec '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14.

[Dovecot] convert_mail ?
by Andrew Z 04 Dec '06

04 Dec '06

I can't find much documentation on the convert_mail plugin. For example, on the wiki plugins page, clicking on convert goes to <http://wiki.dovecot.org/InterWiki> which is not relevant. Can I use convert_mail to migrate from UW IMAP 2002 mbox format where some mail is in ~/ and the inboxes are in /var/spool/mail? Will it know which files are mbox folders, so it doesn't try to convert other files in the home directories? When are the e-mails converted? Are the old files deleted? Is this configuration snippet valid? default_mail_env = maildir:~/Maildir convert_mail = mbox:~/:INBOX=/var/mail/%u If I can do that, it seems like an easy change. Andrew
