[Dovecot] FETCH order fix backport to stable from test66
by Chris Wakelin 05 Apr '05

05 Apr '05

I've had a go at back-porting Timo's recent fixes to the IMAP fetch command from 1.0-test66 to 1.0-stable. This seems to fix the problem with kmail, and Thunderbird seems to work fine without its RFC822.SIZE fix. It's a bit big for the body of this message, so it's attached. The bit I'm most concerned about in my port is whether I got the buffer_insert call right (back-ported from an array_insert call) in imap-fetch.c :- @@ -119,8 +129,14 @@ memset(&h, 0, sizeof(h)); h.handler = handler; h.context = context; + h.buffered = buffered; - buffer_append(ctx->handlers, &h, sizeof(h)); + if (!buffered) + buffer_append(ctx->handlers, &h, sizeof(h)); + else { + buffer_insert(ctx->handlers, ctx->buffered_handlers_count * size of(h), &h, sizeof(h)); + ctx->buffered_handlers_count++; + } } Best Wishes, Chris --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+-- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094

[Dovecot] ldap auth with test66
by Thomas Hummel 04 Apr '05

04 Apr '05

Hello, The installation of 1.0-test66 (still on FreeBSD 5.3-RELEASE-p1 with openldap-2.1.27) solved the SIGSEV problem I posted here on March 30 but I still cannot authenticate correctly with ldap. logs report "ldap(dovetest,127.0.0.1): No password in reply" and my client gets a "NO Temporary authentication failure." Obviously the attr_names array of the passdb_ldap_connection struct is valid until the preinit function but has been corrupted when we're at the passdb_init function. For instance, here's what I get in the log file for the 'fields' value : --- dovecot: Apr 04 11:43:19 Info: Dovecot v1.0-test66 starting up dovecot: Apr 04 11:44:58 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AGRvdmV0ZXN0AHBhc3M = dovecot: Apr 04 11:44:58 Info: auth(default): ldap(dovetest,127.0.0.1): base=ou= personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(u id=dovetest)) fields=0^S^<^S^d^S^°^S^ð^S^^T^T^Ð^T^Ø^T^^C -- Beside, I could notice, by adding some logging info, that the attr_names seem to hold the USER attrs instead of the PASS attrs. I'm trying now to investigate further through gdb (I added a sleep in the main of dovecot-auth to be able to attach the running process in gdb) but without success for now. Do you have any clue of where I should look ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Nested folders
by Michael Irons 03 Apr '05

03 Apr '05

I would like to have nested folders that users could create from their MUA. The problem is that I cannot create sub folders either through the MUA or by hand on the server side. I can make folders that are not the subfolder of anything. I have an Inbox, Mailing Lists, Spam, Trash, etc. But I cannot create subfolders of these. For example, I would like a subfolder under Mailing Lists for each Mailing list that I have subscribed. I am using Postfix that delivers directly to procmail which puts mails into Maildir style mail boxes in each users home directory. I am using the dovecot-0.99.13-4.FC2 rpm if that helps. I am sure that there would be some information about this somewhere, but I haven't found it in the mailing lists or googling around. The only information I have been able to find is that dovecot reportedly supports this. Thanks, Mike

[Dovecot] We couldn't drop root group privileges
by J. Erik Heinz 03 Apr '05

Hi, I just installed dovecot. The installation went well and i configured dovecot to user ~/Maildir. When I tested imap via telnet the login work, but right after that the connection is cutted: Trying 192.168.0.14... Connected to op. Escape character is '^]'. * OK dovecot ready. . login jerik password . OK Logged in. Connection closed by foreign host. And the log says: dovecot: Apr 02 19:37:18 Info: Dovecot starting up imap-login: Apr 02 19:38:03 Info: Login: jerik [192.168.0.23] imap(jerik): Apr 02 19:38:03 Fatal: We couldn't drop root group privileges dovecot: Apr 02 19:38:04 Error: child 15194 (imap) returned error 89 So the problem is that dovecot "could't drop root group".

That's why I don't understand the erros message. By the way, through the installation there was the user and group dovecot created, should this user start dovecot at boottime? Or should he be used for other tasks? Regards Erik -- J. Erik Heinz Koblenzer Str. 11 60327 Frankfurt am Main Handy: 0163 337 37 45 Mail: jheinz(a)wiwi.uni-frankfurt.de

[Dovecot] Multiple auth method problem
by Timshel Knoll-Miller 03 Apr '05

Hi, I'm having issues getting the multiple authentication methods of dovecot 1.0-test65 to work correctly on NetBSD. I am combining a MySQL database of virtual host accounts with the system password database of local machine accounts.

[Dovecot] Trouble with basic Dovecot setup
by paul wisehart 03 Apr '05

03 Apr '05

Hi, I have compiled dovecot-1.0_stable. (http://dovecot.org/nightly/stable/dovecot-stable-20050328.tar.gz) I have it set to "userdb = passwd" & "passdb = passwd" I have a user "wise" with an maildir type mailbox at ~/Mail The actual maildirs are all subfolders with the INBOX "inbox" being one of them. I also have setup the ssl certificates with the script from the source doc directory. I start dovecot, and try to login from a seperate machine running thunderbird. I tell it to use ssl ( 993 ). (I specified both dovecot logs in the config file.) This is what I get from the dovecot logs: "info_log_path = /etc/dovecot/info.log": dovecot: Mar 29 08:30:15 Info: Dovecot v1.0-stable starting up dovecot: Mar 29 08:37:44 Info: Dovecot v1.0-stable starting up dovecot: Mar 29 08:39:04 Info: imap-login: Aborted login [###.###.###.###] I get that last line every time I try to connect from thunderbird. Any ideas? I can give more detailed info as well. thanks! -- paul \ / wisehart >/ <//////$> |\|\|\ -- paul \ / wisehart >/ <//////$> |\|\|\

[Dovecot] QUOTA support timeframe? (also -- folders in folders?)
by Gerald V. Livingston II 02 Apr '05

02 Apr '05

I see it's been in the wishlist a while. Any possible timeframe for getting it working, or maybe a patch (or is it too big a change) to support it? I'm building a new server to move an existing userbase to. So far I have working: Postfix (with Maildir quota patches that work fine) Amavis-new with ClamAV scanning for viruses (will add SpamAssassin soon) SquirrelMail IMP (Horde) (Yes, 2 webmails to allow customers a choice of interface) Right now my test accounts have quotas, but they have no way to see where they stand without IMAP++ QUOTA support. Also, a question. Does Dovecot support folders within folders other than INBOX? I hadn't even thought about that question until I tried to create a test folder from within Squirrelmail and checked the "Let this folder contain subfolders" box and the creation failed ---- nevermind, that must be a Squirrelmail oddity. I created another folder inside the test folder and it worked OK -- just have to NOT check that box. Thanks all, Gerald

Dovecot does not do this. And I don't see a need for that. Configure your MTA to put the envelope data into the mail header (e.g. Return-path and Envelope-to). I used this several times for multidrop-mailboxes (which also seems to be the main use of SDPS).

[Dovecot] virtual user question
by Steve Hoffman 02 Apr '05

02 Apr '05

I'm sorry if this has been asked already, but I'm new to the list and to dovecot. I'm trying to add imap to our existing setup where we host many virtual domains and would like to use dovecot to do it as I find it's one of the most configurable I've seen so far. The problem is that our virtual users passwd files are kept in seperate directories so /etc/virtual/%d/passwd, but I can't use the variable substitution in the dovecot.conf file as it results in a load error because it won't translate the %d. I'm using the latest development release, test65. I read in the config file that you can use many passdb's but do I have to put them all in there or is there a way to use some sort of substitution? The other issue I'm having is when I try to test the connection (with a hard coded path to passwd) it fails auth if I pass the username "user(a)domain.com" but passes if I pass just "user". Any help or places you can point me for these issues? Thanks, Steve

[Dovecot] new to dovecot, dealing with MH foders
by jerry scharf 02 Apr '05

02 Apr '05

Hello, I'm sorry if this is a repeat, a few choice searches into google didn't help and I found no search for the archives. I can no longer put of moving away from UW-IMAP. Dovecot certainly seems to be the right choice, but I am having problems getting it to do what I need it to for all my mail. The machine is running the dist version, 0.99.12. I have a system mailbox and a large MH mail tree (~25K messages.) I saw that dovecot didn't support mh trees like UW did. It looked like maildir would be a good common target. So I found a script that would convert the mbox to maildir and have adjusted postfix, and that all works fine. Then I found mh2maildir, and ran it over my entire mh tree. Then I tried just for a test copying one of the small top level directories under ~/Maildir, but my MUA (mulberry) doesn't see it. So how do I get dovecot to see things other than the inbox in maildir format? How can I easily test to see if it's dovecot's problem or the MUA? thanks for any help, jerry Jerry Scharf laguna way consulting

[Dovecot] FC2 POP3/SMTP Configuration
by Linux Stuff 02 Apr '05

02 Apr '05

OK, let me try this again. . . . I'm a newbie to dovecot and a little bit less of a newbie to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run dovecot (v0.99.14) POP3 and sendmail (8.12.11-4.6) with Mozilla (1.4.2 and others), Thunderbird (1.0.2) and Netscape (7.1 on PC's, etc) mail clients - mostly PC's (W2K, WXP). They all can read their mail but none of the users can send any mail. I have also tested with Outlook and it works!? Ximian Evolution (1.4.6) also works!??? Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database Why do Outlook and Ximian work and the others do not?

[Dovecot] LDA Wishlist idea

02 Apr '05

Hi all, Sorry if this is out of place, but I've seen people suggesting future functionality for Dovecot on here before. TBH I'm not completely sure if this would be possible in a LDA. Demon (an ISP) have extensions to POP3 they call "SDPS" - there's basically an extra command that can be called for an email and it gives the envelope rcpt and from addresses. I was wondering if there was any chance of future versions of Dovecot allowing something similar?

Re: [Dovecot] [ #14832]: Capital letters in POP3 logins
by Gerald V. Livingston II 01 Apr '05

01 Apr '05

I just tested and IMAP doesn't ignore case either. Remove the UPPER CASE maildir created by your POP3 login then do the same thing with an IMAP client. Set up the IMAP client to use an UPPER CASE username and when you log-in/refresh folders it creates the new UPPERCASE empty Maildir all over again. Crap, between this and the missing QUOTA feature I guess I'm gonna have to rip out Dovecot and use Courier. I really wanted to use Dovecot for it's speed with the indexing. What I don't understand is -- all usernames in my test database are stored in lower case -- shouldn't it simply fail to match and cause the login to fail? Can anyone point out how to force the match to be case sensitive? I'll investigate and get back to the list. It would be "nicer" though if Dovecot converted all username input to lower case before authenticating to maintain uniqueness of email addresses.

[Dovecot] test65 killed by SIGSEV
by Thomas Hummel 31 Mar '05

31 Mar '05

Hi, I had successfully set up dovecot-1.0-test62 + ldap pass/user db, but now I'm encoutering a SIGSEV problem with a similar set up of a brand new dovecot-1.0-test65 installation. The auth process is killed by a SIGSEV as reported in the error log file : dovecot: Mar 30 17:06:59 Error: child 28291 (auth) killed with signal 11 To be precise, the problem occurs in the "ldap_lookup_pass" function (auth/passdb-ldap.c) just before loging the ldap request parameters (auth_request_log_debug) and to actually perform the search (db_ldap_search). The signal occurs on the call of t_strarray_join(attr_names, ",") What I'm observing is that the "attr_names" array of the "passdb_ldap_conn" ldap connection doesn't seem to hold the right attributes : while in the test62 version it holded 'uid' and 'userPassword', it holds now 'uid' and 'homeDirectory'.

[Dovecot] Pine and prefix - LIST command bug?
by Chris Wakelin 31 Mar '05

31 Mar '05

I've been having problems with Pine 4.62 talking to Dovecot 1.0 stable. It's fine when the folder collection path is empty, but if I have "~/mail/" or "mail/" it gives access errors (I'm using the "~/mail/", "mail/" etc. hidden namespaces for backwards compatability). It seems to me that Dovecot is not replying correctly to a "LIST" command with empty mailbox name: - Dovecot: xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" "" xyz LIST "mail/" "" * LIST (\NoSelect) "/" "" UW-IMAP; xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" ~/ xyz LIST "mail/" "" * LIST (\NoSelect) "/" mail/ RFC 2060 says: An empty ("" string) mailbox name argument is a special request to return the hierarchy delimiter and the root name of the name given in the reference. The value returned as the root MAY be null if the reference is non-rooted or is null. In all cases, the hierarchy delimiter is returned. This permits a client to get the hierarchy delimiter even when no mailboxes by that name currently exist. Mind you, it looks like at least our UW-IMAP also gets it wrong for "~/mail/". Of course, I may be misunderstanding something!

Re: [Dovecot] [ #14832]: Capital letters in POP3 logins

support(a)majordomo.ru wrote: > Can I solve this problem or it is virtually "bug" of dovecot? No bug, just the "garbage in, garbage out" principle. Mysql's string matches are case-insensisitive by default, so when dovecot asks mysql for the user information of UsEr1, it will get the information of user1 and therefore assumes that UsEr1 is a valid login. It's not dovecot's fault. If you want the match case-insensitive (so UsEr1 will be rejected), add the BINARY attribute to the userid field or change your query to '... WHERE BINARY userid = "%u"' in password_query and user_query. If you want to allow logins as UsEr1 (and let him access user1's mail), you have to change your dovecot.conf, I think. Use %h instead of %u there, and let user_query return the home directory with something like 'SELECT CONCAT('/var/spool/vmail/',LOWER(userid)) AS home, ...'.

[Dovecot] [ #14832]: Capital letters in POP3 logins
by support＠majordomo.ru 30 Mar '05

30 Mar '05

Hello all! I'm newbie here :) Using dovecot (version 1.0-test59, with mysql-auth) I saw strange problem: after authentication by POP3 in case that username given has capital letters, for example SupportTeam(a)majordomo.ru, dovecot creates new maildir 'SupportTeam' for this username instead reading mails from existing maildir 'supportteam'. Then dovecot scans created maildir 'SupportTeam' and returns 0 messages (sure:). IMAP4 works fine in the same time. Can I solve this problem or it is virtually "bug" of dovecot? Thanks in advance!

[Dovecot] Chrooting dovecot.
by BSD Mail 30 Mar '05

30 Mar '05

Greetings, I have installed Dovecot under FreeBSD 5_3 It is pretty impressive. I got SSL working with no problem for both imap and pop3. Besides that I do still want to chroot Dovecot. I noticed that there are some options in the dovecot.conf that are intended for this. Unfortunately online resources on how to do that can't be found on google. Although I'm running the server as user dovecot. I still do have this: dovecot pop3-login 491 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 490 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 489 1 tcp4 10.0.1.4:995 *:* dovecot imap-login 488 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 487 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 486 1 tcp4 10.0.1.4:993 *:* root dovecot 481 5 tcp4 10.0.1.4:993 *:* root dovecot 481 6 tcp4 10.0.1.4:995 *:* Fine for the first six lines it's doing what it's doing. But the last two lines are running as root. That is why I want to chroot the server. I would like if anyone can point me to some howto or notes on how to do so. If there is none I will have to configure a jail just for this purpose. Thanks in advance. -- Regards,

[Dovecot] Checkin 1.37 of src/lib-storage/mail-storage.c
by Geo Carncross 29 Mar '05

29 Mar '05

Checkin 1.37 of src/lib-storage/mail-storage.c added a parameter to mailbox_open() but this broke building src/deliver/deliver.c as revision 1.2 doesn't use the new parameter. It looks like save_mail() of src/deliver/deliver.c calls mailbox_open() and it looks like it might work fine if it were to use a (struct istream *)0 as the third parameter (instead of the flags) -- but I don't use deliver [yet], so I don't have any adequate way to test this. -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/

[Dovecot] mbox zlib compression plugin
by Timo Sirainen 29 Mar '05

29 Mar '05

Some people have been asking this forever, but because it wasn't possible to implement it as a plugin, I hadn't done it. Now, due to some API changes for other purposes, it was suddenly easy. So, if you want to try it, grab the latest CVS code / nightly CVS snapshot and http://dovecot.org/patches/1.0/zlib-plugin.tar.gz Compilation instructions inside zlib-plugin.c file. What it does is check if mbox name ends with ".gz", if so it opens it as read-only using zlib. If the file isn't actually zlib compressed, zlib seems to be able to still access it as a normal file (but it's still read-only). It should be possible to implement it for maildir files as well by hooking into mail_get_stream().

[Dovecot] FC2 POP Configurtion
by Linux Stuff 29 Mar '05

29 Mar '05

I'm a newbie to dovecot and a little bit less of a newbit to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run sendmail with netscape mail clients - mostly PC's. They all can read their mail but none of the users can send. Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database I know I must be missing something, probably trivial. Does someone have a simple, easy-to-read, config file for dovecot pop running with sendmail? Thanks

[Dovecot] Address with whitespace shows as ""@MISSING_DOMAIN
by Chris Wakelin 28 Mar '05

28 Mar '05

It seems that Dovecot gets confused when presented with a header like: From: someone(a)somewhere.org i.e. with leading whitespace and no "friendly name" This shows up as ""@MISSING_DOMAIN in clients, such as Pine, that believe what Dovecot tells them rather than parsing the headers themselves (e.g. Thunderbird). Here's a sample IMAP session: xyz FETCH 728 ENVELOPE * 728 FETCH (ENVELOPE ("Tue, 22 Mar 2005 10:10:50 +0100 (BST)" "Test" ((NIL NIL "" "MISSING_DOMAIN")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "" "MISSING_DOMAIN")) ((NIL NIL "" "MISSING_DOMAIN")) NIL NIL NIL "<Pine.GSO.3.96.1010704101043.17798B-100000@suma3>")) xyz OK Fetch completed. Here's UW-IMAP on the same mailbox: . FETCH 729 ENVELOPE * 729 FETCH (ENVELOPE ("Tue, 22 Mar 2005 10:10:50 +0100 (BST)" "Test" ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) NIL NIL NIL "<Pine.GSO.3.96.1010704101043.17798B-100000@suma3>")) . OK FETCH completed I'm not sure I read the RFC correctly, but it looks like whitespace is allowed (and if it wasn't, I'd expect our MTA, Exim to fix it on delivery). There's a particular member of one of the UK academic computing mailing lists who always seems to do this, but I'm not sure how common a problem it is!

[Dovecot] Troubleshooting help
by Paul Michael Reilly 28 Mar '05

28 Mar '05

Somehow, hopefully to be determined, I got my Thunderbird/dovecot Fedora Core 3 configuration into a real snit, such that I can no longer access my INBOX. When Thunderbird tries to get the INBOX content (or get new mail) it reports "The current command did not succeed. The mail server responded: Invalid messageset: -2147483648:*." Scouring logs and googling has come up empty. Now I'm flailing at trying to get to a state that this problem does not exist. I'd like to understand how this situation arose and how to deal with it better if it happens to any other users on my mail server. Thanks, -pmr

[Dovecot] test65 "deliver" LDA bug
by "Branko F. Gračnar" 28 Mar '05

28 Mar '05

Hello. I've tried to implement dovecot's deliver LDA to my home mailserver. I've run into troubles :) dovecot-deliver.conf: -- snip -- mail = maildir:%h/Maildir:INBOX=maildir:%h/Maildir mbox_read_locks = flock mbox_write_locks = flock -- snip -- when i run: deliver -d bfg < email.txt dovecot delivers message to ~/Maildir/maildir/new It acctually creates "maildir" folder inside real maildir folder. If i try to list messages via Outlook express mail client, OE reports entire folder list, but also lists one message "which no longer exists on server". If i remove ~/Maildir/maildir folder this message dissaperas from OE imap folder listing. Test scenario: 1. start dovecot 2. try to deliver message using "deliver" program (succeedes) 3. try to open INBOX via imap: Outlook Express: - reports INBOX message listing with one message, which "doesn't exist on server anymore" - the next delivery test with "deliver" LDA fails (lots of nanosleep() calls) Thunderbird: - reports that there are NO messages in INBOX - still can delivery messages with "deliver" LDA deliver strace output (search for EVIL CODE string): --- snip --- execve("/opt/dovecot/libexec/dovecot/deliver", ["/opt/dovecot/libexec/dovecot/deliver", "-d", "bfg"], [/* 42 vars

[Dovecot] Another imap crash...
by Todd Burroughs 26 Mar '05

26 Mar '05

The segfault problem that was happening seems to be fixed. I'm still getting some "(imap) killed with signal 6" errors. I just noticed that it did get one segfault. Unfortunately, I don't have a core file. I'll try to get one if this happens again. Here's the error messages, not sure if it will help. I'm using the CVS copy from March 24. dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index cache file /mailhome/new/s/support/.imap/INBOX/dovecot.index.cache: indexid changed dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted transaction log file /mailhome/new/s/support/.imap/INBOX/dovecot.index.log: invalid indexid (1111832898 != 1111831599) dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index file /mailhome/new/s/support/.imap/INBOX/dovecot.index: Record UIDs are not ordered dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted transaction log file /mailhome/new/s/support/.imap/INBOX/dovecot.index.log: invalid indexid (1111831599 != 0) dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index file /mailhome/new/s/support/.imap/INBOX/dovecot.index: Record UIDs are not ordered dovecot: Mar 26 05:28:20 Error: child 4282 (imap) killed with signal 11 Todd Burroughs

[Dovecot] quota issue POP3
by Obantec Support 26 Mar '05

26 Mar '05

Hi Just u/g to RH FC3 from RH8.0 which seemed to work fine with quotas. I have quotas for usernames set up as /home/domain/domainX/username/ for web space 50MB say 48MB used so 2MB free and /var/mail/spool/username for email. 100MB (60MB used so 40MB is available). /var/mail/username is symbolic linked via to spool/mail under /var dovecot seems to be using the quota for /home/.. and sees only 2MB so refuses to write file back. maillog is reporting (username and IP replaced). Mar 16 13:20:03 proteus2a pop3-login: Login: username [11.22.33.44] Mar 16 13:20:03 proteus2a pop3(username): Error rewriting mbox file /var/mail/username: Disk quota exceeded Mar 16 13:20:03 proteus2a pop3(username): write() failed with mbox file /var/mail/username: Disk quota exceeded i am assuming this is when pop3 login is trying to re-write file back when deleting emails.

[Dovecot] Postfix SMTP AUTH patch updated
by Timo Sirainen 25 Mar '05

25 Mar '05

There was a small protocol change in later 1.0-test releases which made the older patches not to work. Updated the patch for Postfix 2.1.5 and added patch for Postfix 2.2.1. I also tested that it works with Dovecot 1.0-stable releases. So, if you're interested: http://dovecot.org/patches/postfix/

[Dovecot] Segfault in imap process
by Todd Burroughs 24 Mar '05

24 Mar '05

We've been testing dovecot for a while and I noticed yesterday that imap crashes quite often. It seems to be about even with SIGABRT and SIGSEGV. This one was SIGSEGV. Our system is SuSE Linux 9.2, 2.6.11.5 kernel (also happened with an older 2.6 kernel). Dovecot version is 1.0-test64 and was compiled with: "./configure --prefix=/services/dovecot --disable-ipv6" It's using mbox over NFS and I've configured "mmap_disable = yes". The mailbox that it crashed on is one of our support mailboxes and it is pretty busy. In the last 1/2 hour, it received over 100 emails. I had a look at the code, but didn't notice anything obvious. Thanks for any help... Here's the log messages: dovecot: Mar 22 18:22:23 Error: 19697 IMAP(support): UIDVALIDITY changed (1111532787 -> 1111533642) in mbox file /mailhome/new/s/support/mbox dovecot: Mar 22 18:22:26 Error: child 19697 (imap) killed with signal 11 and a backtrace: mail201:/services/dovecot/var/log # gdb /services/dovecot/libexec/dovecot/imap imap.core.pid19697 GNU gdb 6.2.1 Copyright 2004 Free Software Foundation, Inc.

Fw: [Dovecot] Auto Create Folders
by Chris L. Franklin 24 Mar '05

24 Mar '05

>> the problem might be: what would your mta do if: >> 1. the user never logged in via imap okay, so then they would never get there mail ? I guess I don't see where your going with this problem. >> 2. therefor no folders were created by dovecot .... Ok ?? >> 3. it has to deliver a spam message to the spam folder. Your right the filter would put it into the spam folder, witch it would created if it's not found. And as a side note the "Spam" folder was just a example folder name. Really for are needs it would be a folder called "Meetings" >> "so you have to ensure the folder existance at the user creation level >> imho. thats the logical point to do exactly that. >> checking for folder existance everytime a user might access a service is >> stupid. it costs at least a stat() call per directory." Some how you missed the part.I'd like to make sure this use always has this folder. Aka if they delete it, I'd like it to be recreated. PS. In the end all's it comes down to is i was wounder if there was a way to have dovecot auto create a folder or a list of folders at login. OR really if there was a way to tell dovecot a list of folders a user COULD NOT delete (But could delete the folders in side). -- Chris L. Franklin --

[Dovecot] automatic flag updates
by Aaron VanDevender 24 Mar '05

24 Mar '05

Is there a way to get dovecot to send automatic flag updates? I notice that when I have two clients connected and one of them reads a new message, the server sends a status update which contains the number of unseen messages, but doesn't specifically say which ones have changed. I think the solution to this problem, while not wasting bandwidth, is to issue a unilateral FETCH FLAGS response whenever a flag changes. There doesn't seem to be a way to get dovecot (I'm using 0.99.10) to do this. Can the 1.0-test versions do this? cya .sig

[Dovecot] Hide non-accessable folder from users
by Remy Zandwijk 22 Mar '05

22 Mar '05

Hi all, In our faculty, people keep asking about shared mail folders. With Dovecot up and running this should be no problem. I think we will have about 50 shared folders. I did take a look at the various solutions, but not all of them are useable. For example, I do not want users to create sub-folders in shared folders. This means the symlink option is unuseable. In my opinion, the easiest solution is creating a namespace and create the shared folders in the location of this namespace. Every shared folders gets his own UNIX group ID. Offcourse, this works great. The ony big disadvantage is that every users 'sees' all shared mailfolders, even if the user does not have the proper rights to access the folders. Is there a way to hide the non-accessable folders from users? Best regards, Remy Zandwijk
