[Dovecot] 1.0-test60
by Timo Sirainen 11 Jan '05

11 Jan '05

http://dovecot.org/test/ I've been running this for two hours now without problems. I guess it's pretty stable. - Keyword support finally included. Not too well tested, but I couldn't get it to break. Doesn't store the keywords into maildir/mbox yet. Hopefully soon. - Major reorganization of code in dovecot-auth, and not yet finished. Load balancing between multiple auth procsses (ie. auth_count > 1) was before done by connecting to each one's socket separately. Now there's a single socket which a balancer process listens to and distributes the requests to worker processes. What's left to do is make a single auth process support handling multiple auth sections in config file. This makes it possible to: - have ordering-sensitive fallbacking for multiple passdbs - have fallbacking work with non-plaintext authentication - allow for all kinds of new great features more easily. For example we could add PAM-like "required" vs. "sufficient" selection for auth sections, or some rules when each passdb is used (eg. based on username, domain or IP range). After that it should also be easy to run dovecot-auth standalone because it would read its own config file. I'm also planning on making it compatible with Postfix's master process, so you could directly add it to master.cf (actually I think I only have to move one fd from 3 to 6 and it'd work). - Added "passdb" userdb. Basically means that the passdb already returned all the information needed for userdb. With SQL this means you could do: SELECT password, uid AS userdb_uid, gid AS userdb_gid, home AS userdb_home FROM ... - If authentication failed because of some internal error, tell it to client instead of showing a generic "Authentication failed." error. - MySQL driver supports load balancing between multiple servers. Just add a new host=xx to connect string. It's not currently supported to have different usernames/passwords. Probably not worth it? - rawlog code rewritten. Should work better. - If userdb returns non-numeric UID or GID, look it up from passwd/group. - Rewritten message address parser. The old code could have lost some spaces and might have even returned invalid MIME string because of it. This affected only clients which use FETCH ENVELOPE command. - mbox: If lines began with NUL characters, things broke. Also fixed another potential problem with parsing mboxes. As a result hopefully these fix a problem with expunge sometimes leaving a few extra characters to beginning of mbox. - Added mail_debug setting which logs where and how Dovecot is trying to locate mails. Helpful when initially figuring out why Dovecot isn't working right. auth_debug=yes now also logs all SQL queries and LDAP lookups and some other things. - etc.

[Dovecot] IMAP crashes with signal 10 (SIGBUS)

Subsequent versions still crashed and I looked into the problem further. Specifically it crashes at this line offset = *((const uint64_t *)data); when "data" assumes a non-64 bit aligned value. At first I thought that 64-bit ints should always be aligned on 64-bit boundaries, but when I isolated this code into a standalone executable to demonstrate it (no arguments to cause a crash, one argument is OK): int main (int argc, char *argv[]) { int a[]={1,2,3,4}; long long int i64; void *p=(void *) (&a[argc]);; printf("Pointer to 32-bit int = %x\n",p); i64 = *((long long int *)p); printf("Successful casting to 64-bit int: value=%016llx\n",i64); } I found out that the presence of any optimisation (-O, -O2, -O3) will cause this to crash, yet it will work if no optimisation is present even though a pointer being cast is still not aligned on a 64-bit boundary (but aligned on a 32-bit boundary). I check the gcc bug web page page came up with this reference which may explain this behaviour. http://gcc.gnu.org/bugs.html#known - see section "Casting does not work as expected when optimization is turned on" http://mail-index.netbsd.org/tech-kern/2003/08/11/0001.html They claim that this casting violates ISO aliasing rules and the results like crashing are to be expected. Maybe this statement ought to be rewritten memcpy(&offset,data,sizeof(uint64_t)); There is one other statement at mbox-synbc.c:319 (1.0-test59) that may need this consideration.

[Dovecot] ldap auth (with user and domain a different places)
by Timo Boettcher 11 Jan '05

11 Jan '05

Hi, I am trying to use dovecot with my virtual-hosting setup. I have all users in LDAP like uid=user,dc=domain.tld,o=myorganization for the user with the mail-address user(a)domain.tld. This is also the username that user should use for login, but it is nowhere in the ldap-db in this form together, just user and domain at their own places. Is it possible to authenticate with dovecot against such an ldap-directory? After reading docs and comments in the config-file, I think no, but I am not sure. As I read the source, it is not possible just now, but would be, if I could use %d in the searchbase. Or did I understand something wrong? TIA Timo Boettcher

[Dovecot] dovecot + vpopmail
by Chris L. Franklin 10 Jan '05

10 Jan '05

I was just wondering how dovecot interacts with vpopmail. Does it just call the vchkpw and pass the username and password to it then wait for a it to tell dovecot weather the user is vaild or not ? Does vchkpw pass back the users homedir ? PS. My plan is to just replace vchkpw with a script/program of own. that dovecot can call to auth a user again xmail passwd file. And using "auth_passdb = static uid=<uid> gid=<gid> home=<dir template> mail=<dir template>" to fill in all the holes. -- Chris L. Franklin --

[Dovecot] imap catches sig 11 on EXPUNGE

[Dovecot] migration from bincIMAP
by RYAN vAN GINNEKEN 10 Jan '05

10 Jan '05

Hello all I am using Freebsd 4.10stable, postfix 2.1.5 with SASL and TLS, procmail version 3.22 and binc IMAP 1.2.8 binc uses IMAPdir style mail boxes, Spam assassin, and ClamAV. Wish to convert to dovecot but your program does not support IMAPdir does it??? also i have many user accounts that i wish to use untouched if possible. I guess this is a migration question for the most part i am switching to dovecot because of its ability to use postgre database files and real log file.

[Dovecot] Where are flags stored?
by Adam Pordzik 10 Jan '05

10 Jan '05

Hello, I don't now wheather this is IMAP or actually dovecot-specific, but I hope you people here knows about this at least: Where are flags like seen/unseen or e.g. message-priority stored? My goal is to mark spam or other filtered by procmail as "seen", so that dovecot doesn't notify MUAs about new mail in IDLE mode. Are there any mail-headers, so I can set these with procmail to accomplish that? Thanks for help, A

[Dovecot] Repair/Cleaup Maildir
by Glen Eustace 10 Jan '05

10 Jan '05

After having fought an issue with Courier-imap on FC3 for a week (that is still unresolved), I decided to try Dovecot instead. So far, fingers crossed, the issue has not re-occured. Migrating from courier-imap/sqwebmail to Dovecot/Squirrelmail was reasonably painless but I now have an problem. Is there a utility available to cleanup/repair the maildir tree for each user ? As part of the migration, I copied all of the courierimapsubscribed files to .subscriptions and removed the leading 'INBOX'. This seemed to be enough to get things going. Unfortunately, people who had only ever used webmail didn't have a courierimapsubscribed file. When they next used squirrelmail, a new .subscriptions file was created but didn't contain their folders. I tried to fix this by recreating the subscriptions file for each user and adding in all the .directories in their maildir root. I now have a maildir hierarchy with lots of crud in it. I need a utility to go through and deleted all the files that shouldn't be there anymore and to ensure that the subscriptions files are correct. Does such a utility exist ? If not, can anyone tell me where I can find a good description of what Dovecot expects to find in maildirs so I can write one myself. Any suggestions/help appreciated. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen and Rosanne Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.

[Dovecot] Extremely Slow Pop3 Downloads, Evolution 2.0.2
by Michael Joy 10 Jan '05

10 Jan '05

Hello All, We've been running Dovecot for imap for quite some time and have had little trouble with it. However, we recently switched over to using dovecot for pop3 because of simplicity as well as security issues with the older UW based pop server. I've noticed one serious problem. The only client that seems to have any issue at all with the server is Evolution. In pop3 mode, it takes a minute or more to download a few messages on an inbox with 400+ saved messages in it over gigabit ethernet. Over a DSL connection using MS Outlook 2k3 it takes about a minute total for all messages. Similarly with KMail it takes about 5-10 seconds to download all messages in the pop3 box. The messages trickle in with evolution 2.x, I've tried 2.0.0, 2.0.1, and 2.0.2 and all have this problem. I haven't tried the 1.x series as I don't have any linux boxes that old available to test. So apparently, there's two things of concern. 1. The server is definitely fast enough to handle the large mail box. 2. There's some serious incompatibility in Evolution/Dovecot causing for the 14.4 modem email download speeds over lan. We're running Dovecot 0.99.12 on Debian unstable, however 0.99.11 exhibited this behavior as well. If anyone has some hints, I'd greatly appreciate it. It's annoying having to wait 5-10 min to download mail in the morning when one gets into work ;) If there's any other information I can provide, please ask. Thanks to whichever kind soul finds time to trudge through this problem with us. Michael D. Joy HEP - University of Mississippi mdjoy(a)phy.olemiss.edu

[Dovecot] Cannot access a file with Mulberry from a dovecot server if the mail does not end with a newline character.
by Sven Kirmess 07 Jan '05

07 Jan '05

I use Mulberry 3.1.6 on Windows to read my mails with dovecot 0.99.12 Solaris 9. There are some mail which I cannot read. When I try to open such a mail, dovecot quits and restarts (I can see that with ps, nothing is logged). The Mulberry log just looks like this: | --> #7.2300 Sun Dec 19 12:59:33 2004 | A00009 FETCH 695 (BODY.PEEK[1]) | * 695 FETCH (BODY[1] {61} | | --> #7.2300 Sun Dec 19 12:59:33 2004 | * OK dovecot ready. | | --> #7.2300 Sun Dec 19 12:59:33 2004 | A00001 CAPABILITY | * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE AUTH=PLAIN | A00001 OK Capability completed Looks like it just restarts the connection. The interesting thing is, that I can access the file with Netscape 4.8 via dovecot. The problem is the following: I copied the file in the Maildir directory, opened the copied file with vi and saved it. Now, I run a diff: | $ diff orig:2,S copy:2,S | Warning: missing newline at end of file orig:2,S | 12c12 | < <http://forums.mtgnews.com/attachment.php?attachmentid=35559> | --- | > <http://forums.mtgnews.com/attachment.php?attachmentid=35559> As you can see, vi adds the newline on the last line automatically if you save the file. Now, Mulberry/dovecot is able to read this file. I'm not sure if this is a dovecot or Mulberry problem. btw: This problematic mail was created with Mulberry 3.1.6. ;-) Sven

[Dovecot] Feature-request: ip based access control (libwrap)

Is there plans to use libwrap Or is there already some kind of access control i have missed?? What i really want is a mechanism so i can say: If The request comes from "123.121.212.0" dont offer ssl and accept plain else demand ssl and no plain I now have this (almost) in another imap server by xinetd and two ip addresses. I could solve this by iptables or access list on the router but i would prefer to have it in the software itself.

[Dovecot] Japanese Search
by Kazuo Moriwaka 07 Jan '05

07 Jan '05

Hello, I'm trying to debug search command with Japanese 'ISO-2022-JP' codec. ISO-2022-JP codec needs to keep character cases until convert to UTF-8. For example: * '\033[$B%s\033[(B' means a character sounds 'N' * '\033[$B%S\033[(B' means a character sounds 'Bi' It causes a trouble in searches with Japanese. I found imap/imap-search.c/add_new() makes strings uppercase and fixed. But search results didn't affected.. ;-) I hope I can fix this problem in a few days. But I'm not clear about dovecot's source.

[Dovecot] Using Dovecot with Thunderbird 1.0 on Macintosh

Hi.. (and Happy New Year).. I tried switching over from Apple's Mail client (applemail) that is part of Panther to using Thunderbird 1.0 and find that all of the folders in my imap mailbox are messed up.

[others] Software Updates Sonnet ... [others] Any ideas on what is going on here? I just moved to DoveCot 0.99.12, but it doesn't appear to make any distance. Also, if I try to pull up any of the weird folders in Thunderbird, it of course complains about the folders not existing.. Any ideas on how to get around this would be much appreciated!

[Dovecot] possible bug with mail->get_header and caching?
by Johannes Berg 06 Jan '05

06 Jan '05

I don't know if this is intended or not, but here it comes. I have * that copy plugin I was working on * dovecot 1.0-test59 * thunderbird test client My copy plugin looks for the X-DSPAM-Signature header line, and reports it to syslog as such: imap: we have a signature: "X-DSPAM-Signature: <sig>" where <sig> is replaced by what is found in the header line. This only happens when I copy in/out of the SPAM folder (which works fine). Now, when a mail is copied from INBOX to SPAM that doesn't have the signature line, I return an error to the client saying the user can't do that copy since the signature line is necessary. I detect the condition of not having that signature line by checking like this: if (!(signature = mail->get_header(mail, "X-DSPAM-Signature")) { ... return error ... } This works fine, error comes back. Second try, copying a mail that has the header line: works. So, lets do some code changes, disconnect and reconnect to reload the plugin. All of a sudden, copying mails that don't have the header line works too! Uhh? Lets go looking at syslog: imap: we have a signature: "X-DSPAM-Signature: " The only rational explanation I could come up with is that dovecot caches the header line and somehow decided that since it knows about the X-DSPAM-Signature header line mails that don't contain it should have an empty version of it. Well, I can of course test for this (and I actually should anyway, an empty signature isn't useful to dspam), but I do think this is a bug since it makes distinguishing between empty and non-present header lines impossible.

[Dovecot] PostgreSQL user database
by Marco Herrn 06 Jan '05

06 Jan '05

Hi, I am using postgresql for my password and user databases. The problem is, that the information needed in the user database is held in more than one table. But it seems to me that dovecot expects to get all the information for mailbox, uid, gid and home in _one_ query. Is there a way to get around this? Maybe even getting some of this information by another way than pgsql (this is more a rethorical question, since I have this information in the DB, but sometimes it is useful to get, for example the location of the mailbox by another way than the uid and gid). But my primary question is if I can set these fields in different queries.

[Dovecot] virtual hosting
by Tom Allison 06 Jan '05

06 Jan '05

I'm trying to figure out how I might set up some virtual hosting accounts for my server. domain1 would be delivered via procmail to ~/Maildir mail directories domain2 would be delivered via postfix to /var/mail/vhosts/domain2/username and similarly for additional domains. There's also one domain that's delivered to another machine, but that's not a dovecot issue. I just mention it for completeness. currently I have only domain1 and only: default_mail_env = maildir:~/Maildir I'm not really sure how to set this up for additional locations of maildir:/var/mail/vhosts/%d/%n/Maildir (This seems right?) Right now I'm wondering if I have to do one of the following: create two instances of dovecot with seperate configuration files? move everything to /var/mail/vhosts/%d/%n/Maildir data structure and the rewrite all my local (~/Maildir) procmail rules to manage delivery.. This is seeming sticky?

Does anyone have a clue how I might set Dovecot up to allow another account to have read/write access to my INBOX and one other folder? I want to set things up so my assistant can pre-scan my post-Spamassassed email to remove more spam from it. Thanks! Doug

[Dovecot] 0.99.1[12] IMAP problems with Apple Mail.app?
by Jim Tittsler 06 Jan '05

06 Jan '05

Is anyone else having trouble using the Apple OS X Mail.app with a Dovecot IMAP server? With 0.99.11 and 0.99.12 attempting to read certain messages using IMAP or IMAPS seems to put Mail.app into spinning pizza of death mode. Sniffing the connection, it looks like it happens after the client issues a BODY.PEEK[] and the server has responded with the (UID XXXX BODY[] {YYYY}...) and OK Fetch completed. I've only been able to catch it happening with messages that are either (a) Base64 encoded or (b) those that claim to be multi-part/alternative, but only seem to contain a single part. The client acts like it has received the message, since if I kill Mail.app and restart it, I am able to read the problem message from its cache. Is this a Mail.app bug? Is it something about the way Dovecot is responding to the BODY.PEEK[] in these cases? Using Mail.app with the Novell myrealbox.com IMAP I haven't seen problem, even with a test problematic message I redirected there, although admittedly I'm changing the headers by doing the redirection. I haven't gotten 0.99.13rc3 to get past the autotools stage of complaining about AM_ICONV (and a number of AC_ warnings), so I've yet to try it.

[Dovecot] pop3 and home directory

I have a question regarding dovecot (1.0-test52) and pop3. I have users that do not have home directories, they only have an inbox in /var/mail. When they try to pop their email, dovecot tries to create ~/mail and then fails. Is there a way around this or will all email users need to have a home directory?

v0.99.13 2005-01-06 Timo Sirainen <tss(a)iki.fi> * GNUTLS support hasn't been working for a while, so it's not even tried to be used anymore unless explicitly wanted. + Added CRAM-MD5 authentication mechanism. Patch by Joshua Goodall + Added SMD5 and LDAP-MD5 password schemes and changed MD5 scheme to use LDAP-MD5 if the password isn't in MD5crypt format. Patch by Joshua Goodall + Workaround for some POP3 client bugs: if message doesn't contain the "end of headers" empty line, add it automatically. + vpopmail supports now all password schemes, most importantly MD5crypt works now without support from libc's crypt() - SQL and LDAP authentication was broken - SEARCH UNKEYWORD wasn't working

[Dovecot] imap client library.

Dear Dovecot developers, I have several question about imap client: - Is there any difference if we want to create imap client that connect to Imap server with user mail format Mailbox or Maildir? Dovecot support both of them, are we need to create different imap client to support both of them? - Does anyone have imap client library other than UW's c-client? thanks for your information, -- Oon Arfiandwi M.

[Dovecot] authenticate authenticated users
by Tzafrir Cohen 05 Jan '05

05 Jan '05

Hi I'm using dovecot on a LAN server. I sometimes read mail from the server itself locally with mutt and sometimes remotely with mutt or mozilla . I would like to avoid typing my password whenever necessary but without writing a plain-text equivalent copy of it locally. It feels quite silly to have to type the password locally becase the imapd does not know that the process is indeed a process of the user tzafrir. It has all the information it neeeds to check that. wu-imapd has something called "pre-authentication": the imapd is run by the user unpriviliged to access mail in the user's home directory. As a bonus this works quite nicely with ssh public key authentication. I know that at least mutt and pine support running a custom command for creating an imap connection. But then again, wu-imapd is built quite, well, differently. Any ideas? -- Tzafrir

[Dovecot] compact folders, expunge, etc
by Mail Admin 04 Jan '05

04 Jan '05

Test58 and test59 breaks "compact folders" and "expunge" in thunderbird and evolution. Messages marked for deletion just sit there as if compacting folders or expunging have no effect. Thunderbird continues to behave erratically with dovecot test builds. I haven't been able to test the imap_client_workarounds=tb-negative-fetch option yet as I'm still running test52. Thunderbird displays blank messages when they are opened, but "Edit as new" shows the message contents. Thunderbird also displays messages that appear to be truncated like: > Hi Peter, > > I will not This body part will be downloaded on demand. Thanks, Derek

[Dovecot] PLAIN-MD5 passwords?
by Peter Clark 03 Jan '05

03 Jan '05

After I found out that {CRYPT} doesn't support passwords longer than 8 characters, I decided to switch over to MD5 for user passwords in my LDAP database. However, while I have no problem with Postfix + SASL, Dovecot fails to authenticate. Relevant bits from /etc/dovecot-ldap.conf: user_attrs = mailAddress,,,,, # The search string is identical to what's found in /etc/saslauthd.conf: user_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) pass_attrs = mailAddress,userPassword pass_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) default_pass_scheme = PLAIN-MD5 When I try to connect using either KMail or SquirrelMail (which worked just fine before I switched schemes), the following error appears in /var/log/syslog: ldap(user(a)mydomain.tld): password mismatch But when I try 'testsaslauthd -u user(a)mydomain.tld -p longpassword' it authenticates just fine. I have the line 'password-hash {MD5}' in /etc/ldap/slapd.conf, and I used 'slappasswd -h {MD5}' to create the MD5 versions of the passwords. Dovecot is v. 0.99.11. If I can't figure out how to get it to work with MD5, I guess I'll have to go back to CRYPT, but it would be nice to have longer passwords... :Peter

[Dovecot] Wanted: gnutls11 support
by Jaldhar H. Vyas 03 Jan '05

03 Jan '05

I talked to Timo about this before and even provided the beginnings of a patch but don't have enough time to really do a proper job. Anyway, dovecot doesn't work with recent versions of the GNU TLS library. As a result, I compile the Debian package with OpenSSL. However some of the other libraries used, such as OpenLDAP are linked against GNU TLS so Dovecot is linked against both. And it is suspected this is leading to bugs. So could some kind soul provide Timo with a patch he can include in 0.99.13? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

That last line actually made it possible for me to be able to log into the server :) I am still getting errors from PAM but it starting to look good. Is there a good HowTo on setting Dovecot to comunicate directly to MySql without using PAM in the middle ? Also, Since Postfix is still not working on my server, I can't actually recive Emails. Is there somewere an example of the files that need to be in the maildir that I can put them in there and test that the email client get's the mail out ?

[Dovecot] SASL AUTH
by Tom Allison 02 Jan '05

02 Jan '05

I'm reading through the dovecot wiki pages for virtual hosting with postgresql/postfix/dovecot/debian and it looks pretty nice but I think I'm going to skip the SASL authentication since I'm in a trusted network. I think all I need to do is skip section 5 entirely and bypass all the sasl references in the postfix section. Technically, I don't think any of the SASL has much to do with the dovecot configuration.

[Dovecot] random pool depletion
by Johannes Berg 31 Dec '04

31 Dec '04

I'm facing a problem with dovecot 1.0 test-59; ever since I installed it and use it my random pool is always depleted whenever someone opens an imap connection. This wouldn't be too bad if the machine was used interactively, but since it is not and other services read directly from /dev/random those are sometimes blocked due to dovecot depleting the pool by reading /dev/urandom. Thus my question: is it really necessary to use random numbers from /dev/urandom for temporary filenames? And even if, couldn't it use less? It apparently uses 8 bytes every time. johannes

[Dovecot] Authentication difficulties
by Timo Sirainen 30 Dec '04

30 Dec '04

There are constantly pretty basic questions in this list (and in my inbox) about how to get user authentication work correctly. This means that the documentation how it all works is either bad, or people don't find it easily. Any ideas how to improve it? I did this now: - Documentation link in dovecot.org now points directly to Wiki, so people don't go read the outdated documents - Upcoming 1.0-tests and 0.99.13 will contain doc/USE-WIKI-INSTEAD file pointing to Wiki: http://dovecot.org/list/dovecot-cvs/2004-December/003928.html - Updated comments in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003924.html - Added pointers to Wiki in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003927.html How good are the Wiki documents about user authentication in general? The content should probably be split somehow to "getting started" vs. "everything there is to know about it" and "system users" vs. "virtual users". I'm not really sure how to best do that though. I think the Wiki in general could be better organized. Wish I knew how.

[Dovecot] Maildir owner importance

I have set up a directory (/var/local/virtualdir/) as the maildir with a special user/group (virtualmail) and in it I create directories for each domain (example1.tld, example2.tld etc) and sub dir's for each mailbox). Only at the moment, apart from the first one, they are all created as with user root as the owner. How important is to have all the directory tree owned by the same user group (virtualmail:virtualmail) ?

hi, it takes me another hour do debug it again, although i already report it for both joshua and timo. the original patch for openldap's md5 crypt has a small bug. in passdb-ldap.c the schema is already PLAIN-MD5 since that was set in the other part of the original patch in password-scheme.c. do anybody use dovecot with ldap and md5 password? i don't think so:-( this patch would be useful to apply before the final 0.99.13. anyway in the current 1.0 series the PLAIN-MD5 and LDAP-MD5 schema are different. at least plain_md5_verify and plain_md5_generate differ from ldap_md5_verify and ldap_md5_generate. why? -- Levente "Si vis pacem para bellum!" --- dovecot-0.99.13/src/auth/passdb-ldap.c.lfarkas 2004-12-22 17:06:25.000000000 +0100 +++ dovecot-0.99.13/src/auth/passdb-ldap.c 2004-12-22 17:06:56.000000000 +0100 @@ -109,12 +109,11 @@ } /* Special case for OpenLDAP's MD5 type */ - if (strcasecmp(scheme, "MD5") == 0) { + if (strcasecmp(scheme, "PLAIN-MD5") == 0) { buf = buffer_create_static(data_stack_pool, 16); if (base64_decode(password, strlen(password), NULL, buf) == 1 && buffer_get_used_size(buf) == 16) { password = binary_to_hex(buffer_get_data(buf, NULL), 16); - scheme = "PLAIN-MD5"; } }

I have a dovecot installing working quite well for around 1000 users using passwd-file authentication. I'm moving to LDAP and would sure love to be able to migrate the existing MD5 passwords. I've tried using ldapmodify to set "userPassword" to {CRYPT}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 and {MD5}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 In both cases, ldapmodify exits without errors but I cannot bind using the new password. Any ideas? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] bidirectional synchronization of dovecot-managed maildirs
by James Leifer 28 Dec '04

28 Dec '04

Hello and happy holidays, I've been thinking about high performance bidirectional synchronizing the mail on my laptop (which is frequently disconnected) and my workstation at work (which is always on and receives all inbound mail). Both run dovecot on top of maildir. I've been playing with offlineimap, unison (which I already use for all my non-mail files), as well as the gnus agent (in IMAP "disconnected mode"). None of these solutions is really satisfactory: * offlineimap treats a message refile between folders as a delete-plus-resend; * unison doesn't understand the semantics of flag changes at the end of files in maildirs; it also has to stat all the files (which can become slow) to detect changes; * gnus agent can't refile messages between folders when in disconnected mode. Perhaps there are better disconnected IMAP modes available for other MUAs, but, it seems like a more general solution would be appropriate. In particular, the "uniq" field of a maildir filename is an easy way of tracking the identity of a message as it gets refiled. My question: would it be difficult to patch dovecot so that it maintained the *same* uniq when copying messages between folders? What about adding hooks that get triggered whenever dovecot copies or deletes messages? These hooks could log the changes. Later, when one tries to sync, one merges the changes from both replicas and then applies them. I'm aware that dovecot has an option to do copies as hardlinks, which is a good start, but still requires one to stat the files to discover which have the same inode. This is *much* slower than simply listing the directories and comparing maildir "uniq" fields. I'm aware that this invariant wouldn't be maintained if other programs modified the maildirs under dovecot's nose, but I'm willing to exclude this possibility. Suggestions? Best regards, -James Leifer

[Dovecot] dspam plugin
by Johannes Berg 27 Dec '04

27 Dec '04

The first version is available at http://johannes.sipsolutions.net/edit/Projects/dovecot-dspam-integration/co… I'm calling dspam for every message, that seemed easier for now. I will probably integrate Tom's idea about storing the messages until a cron-job picks them up at night by just storing signatures into mysql, in which case its easy to do with a single query: INSERT INTO new_spam (user, signature, isspam) VALUES (<user>, <signature>, <isspam>) ON DUPLICATE KEY UPDATE isspam = <isspam> with given values for <user>, <signature> and <isspam> and a key on (user, signature). For now, however, calling dspam for every message works good enough for me, and seems to work. Regards, Johannes

[Dovecot] Worthwile to use quotas?
by Peter Clark 24 Dec '04

24 Dec '04

I'm aware that dovecot doesn't support Maildir++ quotas yet (pity). However, is it still worthwhile to set up something like Postfix + Maildrop to use quotas, or is dovecot's lack of support just going to throw a wrench in the works? Thanks, :Peter

There's good reasons to use Maildir, and there's good reasons to stay with mbox, but avoiding /var/mail is not one of them. mbox is the "classical" format, and Timo (I assume) chose to setup dovecot to use the "classical" location scheme as well, which is to store incoming mail below /var/mail and let users pull it from there and store it however they want at their personal folder below /home. If you are new to all this, actually there is probably a good point in staying close to the "classical" way of doing things, so that you can get help from more sources. I suggest keep receiving mail below /var/mail as mbox files, and play around with mbox and Maildir storage for different (test-)users below /home.

[Dovecot] error when popping mail over DSL
by Jeff Ramsey 23 Dec '04

23 Dec '04

Hi, I have a user who is getting a strange error when popping his mail over a DSL line. The error in my log file is as follows: file client.c: line 237 (client_send_line): assertion failed: ((size_t)ret == str_len(str)) I can POP his mail just find here locally connected to the server via 100bT, but over his DSL link, he gets this error. His mailbox size is 24MB, and he is using outlook w/ the option 'leave a copy of messages on the server'. He has Outlook 2003 and we use Dovecot 1.0 test 42. Is there a timeout limit on the pop3 server? -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

I just installed Dovecot and it is working great. But I need subfolders. Does this mean I need to convert to Maildir format? I found several tools to do the conversion, but is there anything that needs to be changed in Dovecot to make the switch? Any advice appreciated. Thank you, Michael Hipp Heber Springs, AR, USA

[Dovecot] Mixing mbox and maildir
by Kenneth Porter 22 Dec '04

22 Dec '04

Is there some way to add a maildir folder to a mbox hierarchy? My folders are all mbox, but I want to migrate some client-side mail from a client (PMMail2000) that stores messages as individual files, and it might be easiest just to dump all the files into a maildir directory with suitable naming.

[Dovecot] moving messages with bash
by Todd Slater 22 Dec '04

22 Dec '04

I use bogofilter and a script or two to manage junk mail on my home box (fetchmail from POP3, postfix and procmail to local maildirs, mutt for MUA). Since these mails are just files I figured it never mattered that I moved them from one folder to another via a bash script, but some posts on this list make me think I shouldn't do that on a server running dovecot (IMAP). What I currently have is a MakeJunk folder (maildir) that I drop spam that was missed into, then a cron job runs mail in that folder through bogofilter and moves it to a Junk folder. Is it sane to do that with simple mv, or do I need to use some special imap command? Confused, Todd

[Dovecot] Stalled Authentication, Great Clues
by Richard Petty 21 Dec '04

21 Dec '04

I've just installed Dovecot 0.99.12.1 onto a White Box EL 3 server. I'm mostly following the email server setup instructions at http://www.wanderingbarque.com/mailserver.html and getting Dovecot to work is the last task to complete. I've compiled Dovecot with LDAP support. I'm authenticating Postfix via SASL to the LDAP database just fine, and I also authenticate and manipulate LDAP info from JAMM very well, too. However, Dovecot authentication seem to hang up when a correct password is submitted (POP or IMAP... it doesn't matter). Here's an example of the problem: [root@kayak /etc] telnet localhost 110 Trying 127.0.0.1... Connected to localhost.bramble.com (127.0.0.1). Escape character is '^]'. +OK dovecot ready. user repetty(a)bizzy.mine.nu +OK pass bogeybogey sadf hello? ^] telnet> q Connection closed. As you can see, once I hit the return key to submit the password I do not get another prompt. In fact, Dovecot doesn't respond at all although it seems to respond to the escape character just fine. Additionally, dovecot-auth starts soaking up CPU time... until I kill the process (dovecot-auth must be killed manually.) 22:15:32 up 32 days, 21:40, 5 users, load average: 1.05, 1.02, 0.98 121 processes: 119 sleeping, 2 running, 0 zombie, 0 stopped CPU states: cpu user nice system irq softirq iowait idle total 50.5% 0.0% 0.5% 0.0% 0.0% 0.0% 48.8% cpu00 66.7% 0.0% 0.0% 0.0% 0.0% 0.0% 33.2% cpu01 34.4% 0.0% 1.1% 0.0% 0.0% 0.0% 64.3% Mem: 318260k av, 300740k used, 17520k free, 0k shrd, 24380k buff 141540k actv, 28364k in_d, 3864k in_c Swap: 655352k av, 80868k used, 574484k free 94736k cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 23846 dovecot 25 0 1928 1928 1352 R 49.7 0.6 27:30 0 dovecot-auth 23847 dovecot 15 0 1072 1072 868 S 0.0 0.3 0:00 1 imap-login 23848 dovecot 15 0 1072 1072 868 S 0.0 0.3 0:00 1 imap-login 23849 dovecot 15 0 1160 1160 936 S 0.0 0.3 0:00 1 imap-login 23850 dovecot 15 0 1136 1136 928 S 0.0 0.3 0:00 0 pop3-login 23851 dovecot 15 0 1140 1140 928 S 0.0 0.3 0:00 1 pop3-login 23852 dovecot 15 0 1140 1140 928 S 0.0 0.3 0:00 0 pop3-login 23858 dovecot 15 0 1068 1068 868 S 0.0 0.3 0:00 0 imap-login 23870 dovecot 15 0 1064 1064 864 S 0.0 0.3 0:00 1 pop3-login 23886 dovecot 15 0 1060 1060 864 S 0.0 0.3 0:00 1 pop3-login 23916 dovecot 15 0 1064 1064 864 S 0.0 0.3 0:00 0 pop3-login From the client's point of view, the server never seems to come back after the account password is submitted.

[Dovecot] Postfix + dovecot-auth
by Timo Sirainen 20 Dec '04

20 Dec '04

I wrote a patch to Postfix which now supports SMTP AUTH using dovecot-auth. This time it doesn't need any Dovecot libraries and it's backwards compatible with Cyrus SASL by default. You'll just need to set one variable in Postfix config file to enable it. Patches and instructions in: http://dovecot.org/patches/postfix/ Not very well tested yet though. And it doesn't work with 1.0-test59, you'll need to have at least today's nightly snapshot.

Any problems with this approach? Thanks, Doug

[Dovecot] Error indexing mbox file /var/mail/seb: LF not found where expected
by Sebastian 20 Dec '04

20 Dec '04

Howdy all, Dec 19 14:24:53 dev imap(seb): Error indexing mbox file /var/mail/seb: LF not found where expected I just installed version dovecot-0.99.12.1 for the first time on FreeBSD 4.10 stable. This error occurs when I try to check my mail from a remote client and I have new messages. Here is my configuration: http://unf.be/dovecot.conf It's very close to the default install. In attempts to remedy the problem, I set "mail_read_mmaped = no", but the problem persists. I'm not sure if it's relevent, but I'm receiving mail with postfix and my mail file has lines that end with \r\n Thanks in advance for any help Sebastian -- ------------- buddhahead(a)gmail.com

[Dovecot] Auth Mechanism
by Tom Allison 19 Dec '04

19 Dec '04

Uh... I'm trying to debug an application and keep running into this: DEBUG: Sending: 1 AUTHENTICATE CRAM-MD5 DEBUG: Sent 25 bytes DEBUG: Read: 1 NO Authentication failed: Unsupported authentication mechanism DEBUG: Read: * BYE Disconnected for inactivity. So is this really asking for "digest-md5" or am I S.O.L? IIRC these are different protocols, but it's a bit early for my head to get this together.

[Dovecot] Authentication problems
by Rory Campbell-Lange 19 Dec '04

19 Dec '04

Hi. I aim to provide pop3 and imap services to a few users. At the moment I only offer imap for squirrelmail users. However, I can't login successfully for pop3. It appears to be trying to auth against PAM, rather than directly using the passwd-file. Thoughts? Thanks, Rory Config: uthenticatprotocols = pop3 imap ssl_disable = yes login = imap login = pop3 mail_extra_groups = mail auth = default auth_mechanisms = plain auth_userdb = passwd-file /etc/dovecot.passwd.conf auth_user = root auth_verbose = yes Password file: # squirrelmail imap users user1:xe9l8sIMpcTsg:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user1 user2:m7VKCgWVmZYMY:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user2 user3:ELh9mthLVjEG2:1008:1008::::chroot:Maildir:/home/cmp/Maildir/user3 # normal users xyz1:QtR.iN1DbL/UM:1004:1004::::chroot:mbox:/var/mail/xyz1 xyz2:y38.qLIgrvYic:1002:1002::::~/Mail:mbox:/var/mail/xyz2:INDEX=/home/xyz2 ...

[Dovecot] 1.0-test59
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ No-one had been testing 1.0-tests with Evolution? It was pretty much completely broken with messages having attachments. - test58's output stream code change were entirely wrong and caused bad breakages with mbox. - Named pipes are now treated as write-only mboxes (blocks if no-one is reading, perhaps it should timeout in a few seconds?) - FETCH BODY[n.xxx] replies were all wrong - LDAP authentication was crashing - pop3_uidl_format=%f from Andrey test60 will probably have keyword support. Its index file code is already working, with ability to set over 500k different keywords per mailbox (because message record size is limited to 65535 bytes - should be enough for everyone :). Code is still missing to notify other session about keyword changes, and storing the keywords into mbox/maildir. For mbox I can use X-Keywords header. There should probably be some configurable limit to how many keywords to set per mailbox.. Dovecot shouldn't mind if the X-Keywords header is huge, but other programs might. For maildir then.. I think I'll just implement it backwards compatible with 0.99.x, ie. store in maildir filename with a-z letters. That would make max. 26 keywords per mailbox. Except maybe I shouldn't limit it to that. The rest could be stored only in indexes. That however would make it necessary to keep indexes backwards compatible forever so data is not lost.

[Dovecot] 0.99.13-rc1
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/rc/ I guess the RCing in 0.99.12 didn't help that much. SQL/LDAP authentication crashed because memory was freed wrong. Please test so it would actually work in 0.99.13. Also fixed SEARCH UNKEYWORD which wasn't working. Also added 1.0-test's oe-ns-eoh POP3 workaround built-in.

[Dovecot] Cygwin and index code
by Johannes Berg 19 Dec '04

19 Dec '04

As I can currently only work with windows (eek) I thought I'd try dovecot there. I already sent a patch to make dovecot compile under cygwin, but it still doesn't really work, here's part of a session that I started while my maildir was totally empty (only cur/new/tmp in ~/Maildir) $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Warning: Compressing cache file /home/jmberg/Maildir/dovecot.index.cache imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:51:06] A02 LOGOUT * BYE Logging out A02 OK Logout completed. A second session (some files were created by the first) yields this: $ ./imap.exe * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS] Logged in as jmberg A01 SELECT INBOX imap(jmberg): Error: open() failed with file /home/jmberg/Maildir/dovecot.index.tmp: Permission denied imap(jmberg): Error: rename(/home/jmberg/Maildir/dovecot.index.tmp, /home/jmberg/Maildir/dovecot.index) failed: Permission denied A01 NO Internal error occured. Refer to server log for more information. [2004-12-17 15:52:25] A02 LOGOUT * BYE Logging out A02 OK Logout completed. I think this is probably due to the indexing code opening the .tmp file and then unlinking it and trying to re-create it while the first is still open. Or something, I really am not sure. *Maybe* the index code might be made work if it creates a new temporary file-name every time it re-creates the file, but I don't understand the code well enough (yet) to give a better analysis of the problem. However, I do not think that this is really important. I certainly don't want to run dovecot on windows (I only saw cygwin compile in the todo and since I have a cygwin setup anyway I thought I'd try). The whole thing doesn't work anyway: [after correcting users, making directories, make install...] $ /usr/local/sbin/dovecot.exe dovecot: Dec 17 16:03:17 Info: Dovecot v1.0-test58 starting up dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: Login process died too early - shutting down dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: login: fd_read() failed: Function not implemented dovecot: Dec 17 16:03:18 Error: close(mail client) failed: Bad file descriptor dovecot: Dec 17 16:03:18 Error: imap-login: dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 32): Invalid argument dovecot: Dec 17 16:03:18 Error: auth(default): dovecot: Dec 17 16:03:18 Fatal: setrlimit(RLIMIT_DATA, 256): Invalid argument dovecot: Dec 17 16:03:18 Error: child 2176 (auth) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2192 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2212 (login) returned error 89 dovecot: Dec 17 16:03:18 Error: child 2232 (login) returned error 89 Maybe someone cares.

[Dovecot] 1.0-test58
by Timo Sirainen 19 Dec '04

19 Dec '04

http://dovecot.org/test/ - Fixed APPEND hanging in some situations. Didn't happen with mail_save_crlf=yes. - Added pop3_uidl_format setting. No need to patch sources anymore if you don't want the default. Does anyone want pop3_uidl_xuidl_header yes/no setting, with fallbacking to pop3_uidl_format if X-UIDL header isn't found? Shouldn't be difficult to do.. - Added mbox_very_dirty_syncs setting which tries to avoid re-reading mbox as long as possible. - CREATE dir/ wasn't working - If login_process_per_connection=no and auth process count > 1, each auth process listens in different socket. Login processes then connect to all these sockets and send requests to them in round robin. - Multiple auth sections in config file work now a bit better. dovecot-auth might still complain about timeouts though.

[Dovecot] deploying dspam
by Johannes Berg 17 Dec '04

17 Dec '04

Hi everyone, I've been thinking of phasing out my spamassassin installation (it's hardly doing me any good these days) in favour of dspam. Now since I'm working on this anyway, I thought I'd configure it so when users get any spam, it is delivered into a special folder. I figure I need the 1.0 test series for this, so I can make that folder fixed. But, I also want to allow them to move spam in and out of that folder and dspam can learn it. Anyway, I found a message dating back a while where Timo says this could easily be implemented in a plugin (in the 1.0 test series), but I can't put my finger on how to do it. Does anyone have an example plugin that can run commands when mail is moved in or out of a special folder? Or is there any plugin-writing documentation? Thanks, johannes

[Dovecot] IMAP Subdirectories
by Rory Campbell-Lange 16 Dec '04

16 Dec '04

Hi Using Apple Mail I cannot make subdirectories within new directories I have made on a Debian Dovecot-driven IMAP server (version 0.99.11-3). Some users, having used Exchange, expect to be able to do this. However I can't make it happen, even after doing some tests by chmod-ing the top-level directories to 777 and enabling the mail_full_filesystem_access = yes option on a test install. Views, comments and remarks much appreciated! Rory -- Rory Campbell-Lange <rory(a)campbell-lange.net> <www.campbell-lange.net>

[Dovecot] 1.0-test57
by Timo Sirainen 16 Dec '04

16 Dec '04

http://dovecot.org/test/ Two important fixes: - Fixes the recently reported dovecot-auth crashes with unexpected client input - Fixes mbox corruption in some not-so-common cases. Hopefully this is the last one. I added more asserts anyway which try to catch similiar mistakes and avoid losing data. Others: - Added oe-ns-eoh workaround for pop3. Fixes outlook/netscape problems with buggy mails. - lock_method = dotlock works now properly - Cache file compression crashed in some situations - auth_cache fixes from Andrey Also I have about 80% of the code written for keywords support. It's about the last major missing feature from v1.0, so naming should change into 1.0-alphas soon. From there on it should be mostly about stabilization, cleaning up the code and maybe some optimization.

[Dovecot] Dovecot SQL auth problem? (1.0-test52-56)
by Andrew Hutchings 16 Dec '04

16 Dec '04

Hi there, We are living dangerously and using the test versions on our production servers which are migrated from 3 different older servers (about 5000 accounts) therefore we have 3 different MySQL auths. All seems to be ok, but a guy in the office is using Thunderbird as pop3 access. The auth is saying: auth(sql): plain(?,xx.xxx.xx.xxx): invalid input I have hidden his IP for security reasons. The login should be user(a)domain.co.uk and his account works fine with outlook. With test 52 this killed the auth child with signal 6 and 11. Anyone have any ideas? Unrelated to this (I hope) we are also getting quite a few child xxxx (pop3) killed with signal 11 several times a minute. -- Andrew Hutchings Systems Operator / Developer / Linux Guru Netserve Consultants Ltd. http://www.domaincity.co.uk/

[Dovecot] KMail + dovecot
by Timothy Murphy 16 Dec '04

16 Dec '04

Is anyone running docecot on a home LAN. to give an IMAP feed to other machines on the LAN? I am running dovecot on my desktop, alfred. I want to collect email on my laptop, william, using KMail. As far as I can tell, dovecot is running perfectly. I can bring email from /var/spool/mail/tim on alfred to the same directory on william by running "fetchmail alfred" on william. I can then read it with KMail on william, so there is not real problem. However, KMail does not seem to be able to collect email directly from alfred, even though I have added an entry in KMail=>Settings=>Configure KMail=>Network=>Receiving giving type imap, Name (dovecot), Login, Password, Host (alfred), Port (143). and Prefix to Folders "/var/spool/mail". I don't see any error message anywhere, but when I click on File=>Check mail in dovecot it says "Checking account dovecot for new mail". but nothing appears to happen. Any suggestions or advice gratefully received. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

[Dovecot] Dovecot and PHP
by Don 16 Dec '04

16 Dec '04

Has anyone successfully compiled PHP 5 with the -imap option using Dovecot server? I get the error: "Cannot find rfc822.h. Please check your IMAP installation". It seems that Dovecot has no development libraries so I am stuck? Will I have to scrap Dovecot and use another server like Cyrus? Thanks, Don --- Outgoing mail is certified Virus Free.

Hi folks. New to both dovecot and openldap. Trying to set up virtual domains using the wanderingbarque howto: http://www.wanderingbarque.com/mailserver.html Platform is RH enterprise 3. Only difference is I'm trying to use phamm instead of jamm: http://phamm.rhx.it/ dovecot doesn't seem to want to play nice with my openldap; everything else (postfix, etc) seems to work alright.

[Dovecot] IMAP crashes with signal 10 (SIGBUS)
by Joseph Tam 15 Dec '04

15 Dec '04

Any idea on what's causing this? Description: imap process crashed with SIGBUS. Versions: OS: Solaris 8, 9 Dovecot: 1.0-test57 Gcc: 3.2 Configure options: env CC=gcc CFLAGS="-O -g" ./configure \ --prefix=/var/dovecot \ --disable-ipv6 \ --with-ssl=openssl \ --with-ssldir=/etc/ssl \ --with-passwd-file \ --without-bsdauth \ --without-checkpassword \ --without-pam \ --without-passwd \ --without-shadow \ --without-vpopmail \ --without-static-userdb \ --without-libiconv-prefix \ --with-storages=mbox \ --with-pop3d Interestingly, eliminating optimisation seems to get rid of the problem, suggesting it might be a compiler problem. I've also tried gcc flags "-m32", "-m64", "-O3", "-O2", "-O1" and configure options "--with-file-offset-size=32 --with-mem-align=4" with no relief.

[Dovecot] Tricks to running as normal user?
by Ajaxster 15 Dec '04

15 Dec '04

Hi, I'm running on HPUX 11.11 and have installed dovecot 0.99.12 in my home directory. I've been running it at home on FC2 and had no problems. At work, on HPUX, when I modify the dovecot.conf file like is suggested in the wikki <http://wiki.dovecot.org/moin.cgi/Rootless>, it will detach and I can telnet to the port I've chosen, but I don't get any response back after I connect. Not other processes are getting launched when I connect. I can run the libexec/imap and get capability information echoed to the terminal. I tried the test builds and they seem to be hanging during the parsing of the .conf file. The the process never goes into the background. Does anyone have any suggestions on what I could try to get things running? Thanks very much. -- Jay

[Dovecot] Internal login failure
by Jaeson Schultz 15 Dec '04

15 Dec '04

Hello, I am fairly new to Dovecot, so please forgive me if I am missing something obvious here. I have checked the archived dovecot mailing list messages and have Googled for everything I can think of, and I still have not found anything to help me solve this problem. I am running Postfix+Postgresql+Dovecot on my Fedora FC2 box. I have compiled both Postfix and Dovecot from source. I believe I have postfix running properly. No error messages show up in my logs when starting Postfix or Dovecot. Messages are being delivered by Postfix just fine: Dec 12 11:45:42 co-nundrum postfix/virtual[15759]: 15E82F8EF0: to=<jaeson(a)domain.name>, relay=virtual, delay=1, status=sent (delivered to maildir) However, when I try to login to Dovecot over IMAP I get an "Internal login failure" error: [jaeson@localhost jaeson]$ telnet co-nundrum imap Trying 207.7.137.6... Connected to co-nundrum. Escape character is '^]'. * OK dovecot ready. 1 LOGIN jaeson secret 1 OK Logged in. * BYE Internal login failure. Error report written to server log. Connection closed by foreign host. When I check the dovecot log file I see the following entries: dovecot-auth: Dec 12 01:15:59 Info: PGSQL: Performing query: SELECT password FROM user_accounts WHERE username='jaeson' imap-login: Dec 12 01:15:59 Info: Internal login failure: jaeson [66.159.231.21] dovecot: Dec 12 01:15:59 Error: child 9845 (auth) killed with signal 11 Here are the entries from my dovecot.conf file. As you can see, I have set both auth_verbose and auth_debug = yes, but I don't seem to be getting any log messages with enough verbosity to indicate just what the problem is. base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s imap_listen = * pop3_listen = * ssl_parameters_regenerate = 24 disable_plaintext_auth = no log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log login_dir = /var/run/dovecot-login login = imap login_executable = /usr/libexec/dovecot/imap-login login_user = dovecot login_process_size = 16 login_process_per_connection = yes login_processes_count = 3 login_max_processes_count = 128 login_max_logging_users = 256 max_mail_processes = 1024 verbose_proctitle = yes verbose_ssl = yes first_valid_uid = 5000 last_valid_uid = 65535 first_valid_gid = 5000 last_valid_gid = 65535 default_mail_env = maildir:/mail/%d/%u mail_save_crlf = yes maildir_copy_with_hardlinks = no maildir_check_content_changes = no mbox_locks = fcntl umask = 0077 imap_executable = /usr/libexec/dovecot/imap imap_process_size = 256 auth = default auth_mechanisms = plain auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_passdb = pgsql /etc/dovecot-pgsql.conf auth_executable = /usr/libexec/dovecot/dovecot-auth auth_user = root auth_count = 1 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_verbose = yes auth_debug = yes Additionally, here are the entries in my dovecot-pgsql.conf file: connect = host=localhost dbname=mail_DB user=mailreader password=secret default_pass_scheme = PLAIN password_query = SELECT password FROM user_accounts WHERE username='%u' user_query = SELECT '/mail/'||mailbox AS home, uid, gid FROM user_accounts WHERE username='%u' Finally, here is the configure command I used when building Dovecot from source: ./configure --prefix=/usr --enable-debug --with-pgsql --with-cyrus-sasl2 --with-ssl=openssl --sysconfdir=/etc At this point, I think that the connections to my postgresql tables are all working properly, and the initial authentication with Dovecot appears to be working. Dovecot *does* accept my password and gives me the "OK Logged in." response message, but somewhere before it kicks off the IMAP process it dies with a SIGSEGV. Perhaps I have some file permissions out of whack? Has anyone else encountered this problem, or perhaps has any insight into what might be going wrong or how to find out more information?

That sounds like that's the direction I want to go - I will definitely take a look into that, and possibly tweak it if I can. The way I was thinking about doing it was either respecting one or the other of NO_IMAP or NO_WEBMAIL depending on if you're coming from a local address or a remote one. I might stick with tcpserver using a tcprules.cdb to set environment variables and modify the patch to pass those environment variable(s) onward...we'll see. Or I might just suffer with my many dovecots. > > > I also _think_ I found out the problem, what was corrupting my indexes, > > though I'm not sure.

Yes, unfortunately, the file was unreadable because there was no file system permissions to read it. That actually made dovecot make indices which imply there's nothing in the mailbox. How a file with no FS perms got into my maildir is rather embarassing and I'll skip unless it's important, but it was there and it did hose my indexes.

Hello, I should have sent my first message in plain text instead of HTML so it would show up better in the list archives. Anyhow, I am using the latest release of Dovecot, v0.99.12.1. Seeing as how I don't need the cyrus-sasl2 to be compiled in, I have just rebuilt dovecot without it. Unfortunately I am still getting the same results... [jaeson@shell01 ~]$ telnet co-nundrum imap Trying 207.7.137.6... Connected to co-nundrum. Escape character is '^]'. * OK dovecot ready. 1 LOGIN jaeson secret 1 OK Logged in. * BYE Internal login failure. Error report written to server log. Connection closed by foreign host. The dovecot logs still indicate an "Internal login failure", but offers no extra explanation as to why. dovecot-auth: Dec 13 11:43:04 Info: PGSQL: Performing query: SELECT password FROM user_accounts WHERE username='jaeson' imap-login: Dec 13 11:43:04 Info: Internal login failure: jaeson [216.39.112.19] dovecot: Dec 13 11:43:04 Error: child 25784 (auth) killed with signal 11 I am wondering that since I see the auth_passdb query, shouldn't I also be seeing a log entry for the auth_userdb query as well, or does this happen once the imap process is started? Any advice for how to track down the source of the problem is appreciated. ~Jaeson [This E-mail scanned for viruses]

But I run vpopmail, and I need to make IMAP available only to users who have IMAP 'enabled' (the guys who pay more money). But I need webmail available for _all_ users (even the cheapskates), and my webmail of course uses IMAP behind the scenes. So my solution is one copy of regular Dovecot on port 143, which respects the NO_IMAP flag from vpopmail, and one copy of modified Dovecot, which I patched to ignore the NO_IMAP flag, on port 144 - and then I configured my webmail software to talk to port 144. That copy of Dovecot will eventually only listen to the local network for connections, though currently it listens for anyone. A solution I already tried was having Dovecot run by being invoked from a copy of tcpserver, which used a .cdb 'rules' database which set certain environment variables based upon the users IP address. I patched my copy of Dovecot to listen for those environment variables and pay attention/ignore NO_IMAP based upon those environment variables, but it looks like environment variables get clobbered when dovecot invokes the authenticator process from within imap-login (And the code seems to say that it blows out the environment, too). And I'm willing to bet that it would only work on first invoke of dovecot from imap-login, too, even if it didn't blow out the environment (because the authentication process stays running). All this stuff is, I'm sure, a thousand times easier in something like courier-imap, but I like Dovecot, so I'd rather run two copies of Dovecot than one of courier-imap. So if anyone has any possible direction to go on a solution that lets me run only one Dovecot, I'd love that. Until then, I'm stuck with my hack-ey two-Dovecot solution. I also _think_ I found out the problem, what was corrupting my indexes, though I'm not sure. I think one of the messages in my Maildir was 'unreadable' by Dovecot (well, that's what the logs say). Which seems to completely blow out the index. I got rid of the file, so lets keep fingers crossed that that solves it...

[Dovecot] Ximian Evolution Issue
by Adam Todorski 13 Dec '04

13 Dec '04

Hi This may be a problem with Dovecot and it may be a problem with Evolution, I'm trying to narrow it down. I'm using Evolution 2.0.2 on Fedora Core 3 x86_64 to connect over SSL to Dovecot 0.99.11 on Debian testing (Sarge) on an i686 using Maildir for the mail store. Specifically, when I open a folder with more than a few dozen messages in it I get the following error (with the carroted fields populated): Error while Opening folder imap://<username>@<mailserver>/<folder>. Incomplete server response: no information provided for message <message number>. Thanks for any leads on this! Adam

[Dovecot] Corrupted index files in 0.99.12.1
by Brady Wetherington 12 Dec '04

12 Dec '04

Hi - I've got two copies of Dovecot installed on my server (don't worry, talking to two different sockets for authentication, with two different sets of filenames using options in configure), and I found at least one instance where the index file for my INBOX (on my own account, in fact) got corrupted. So badly so that when I connected via IMAP and selected my INBOX, it said there were no messages there - but if I logged in via sqWebMail (ugh), it said all my messages were there. Note that it didn't give the 'NO can't use index file' message. I moved the .INBOX directory to another filename, and then re-logged in and found that all was well (it regenerated the index files correctly). Would my old, corrupted index files be of any use to anyone? I still have that directory sitting somewhere. Is it perhaps 'bad' to run two copies of Dovecot? I don't know exactly what I was doing, but I can easily imagine accessing one of my Dovecots using my webmail setup, and one using straight IMAP - is that an unsupported setup? I'd also be happy to discuss why I'm using two copies of Dovecot, but that's a whole other discussion :)

[Dovecot] SQL + AUTH command bug?
by Andrew Hutchings 10 Dec '04

10 Dec '04

Hi, While investigating the problem with Thunderbird auths I found the following happening: Escape character is '^]'. +OK Dovecot ready. CAPA +OK CAPA TOP USER UIDL RESP-CODES PIPELINING SASL PLAIN . AUTH PLAIN + + + -ERR Authentication failed. This is what is happening during a Thunderbird connection, when each '+' happens dovecot does an sql query on the sql server for user '?'. This was asserting mech.c until Timo did the bugfix last night. I currently have dovecot authing via 3 separate sql password tables as it is a migration from 3 old servers. If you try any other auth method (which shouldn't work anyway in my case) it doesn't talk to the SQL servers and just comes back as: -ERR Authentication failed.

[Dovecot] Exim4 authentication patch
by Andrey Panin 10 Dec '04

10 Dec '04

Hello all, attached patch makes possible to use dovecot as an authentication backend for Exim 4. Reasons beyond this patch are simple: exim's authenticators require use of plaintext passwords and NTLM code in exim is quite outdated and hairy. Patch generated against Exim 4.43, but should apply to earlier versions too. Patch adds new 'dovecot' authenticator, which can be used as such: ntlm: driver = dovecot public_name = NTLM server_socket = /var/authentication_socket_path server_set_id = $1 cram: driver = dovecot public_name = CRAM-MD5 ... Authenticator has only one parameter 'server_socket', it's value used as path for dovecot's authentication socket. Authenticator can be used for server authentication only. Hope it will be useful for someone. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

[Dovecot] Help needed with debugging auth command
by Andrew Hutchings 10 Dec '04

10 Dec '04

Hi guys, OK, so I am trying to find out why the POP3 AUTH / IMAP AUTHORIZE command is not doing what it is supposed to (not sure if it just for me or what). I am getting as far as: sasl-server.c - line 123 - mech = auth_client_find_mech(auth_client, mech_name); auth_client_find_mech is in auth-client.c which is where I am getting lost. My guess is we are not returning back to sasl-server.c since we don't get an SASL auth or an 'Unsupported' error. If I try 'PLAIN' as the auth method as the parameter then it tries to login with no user or pass and fails. If I try anything else (I have configed to accept plain only) I get 'Authorization failed' and it doesn't even try to lookup the user/pass.

[Dovecot] SHA1
by Marco Herrn 10 Dec '04

10 Dec '04

Hi, I am currently installing doveot as POP and IMAP server, but I a have a few difficulties configuring it correctly. I use postgresql to store the user information. The passwords are stored SHA1 encrypted. Now I have the problem that dovecot isn't accepting the user. In dovecot-pgsql.conf I defined default_pass_scheme = SHA1 I am not quite sure about whether this is corrents, since it is not mentioned in the documentation, but it is mentioned in the wiki (under the name SHA) and it doesn't produce an error (as specifying SHA does). So I assume this is correct. But when I log in with a user I always geht the following log output: dovecot-auth: Dec 08 22:18:20 Info: PGSQL: Performing query: SELECT passwd FROM mailbox WHERE localpart = érwin' AND domainname ='poiu.de' dovecot-auth: Dec 08 22:18:20 Info: pgsql(erwin(a)poiu.de): Password mismatch imap-login: Dec 08 22:18:20 Info: Aborted login [82.82.66.4] dovecot-auth: Dec 08 22:18:20 Info: Login process 9 disconnected dovecot-auth: Dec 08 22:18:20 Info: Login process 9 connected dovecot-auth: Dec 08 22:18:20 Info: Login process 9 sent handshake: PID 22222 Is there a way to get a more excessive debugging? I already set auth_verbose and auth_debug to yes. Or does anyone have an idea what the problem can be here?

[Dovecot] Timeouts with outlook express
by Daniel 10 Dec '04

10 Dec '04

Hi I am using Dovecot 0.99.12.1 (just upgraded) on a site with about 1500 mailboxes. One thing I have noticed is when the client outlook express is receiving a large mail via pop3 it gets a time out. There is traffic. If you click on the "wait" button in the dialogue the mail continues to download. This seem to relate to the "Server Timeouts" setting under mail account Properties/advance. If this setting is set higher the dialogue come only after this time has passed. If the mail take a long time to download if say is very big the user may have to click "Wait" a number of time even if the time out setting is set to the largest amount. It funny because the mail is downloading, So the pop3 server has not stopped responding as outlook express say it has. Strange. What is happening here? and is there a work around for it. Do I have a setting wrong. Regards Daniel ROwe

[Dovecot] SQL + POP3 AUTH command bug - test 57
by Andrew Hutchings 09 Dec '04

09 Dec '04

Hi guys, In addition to my previous message stating that POP3 'AUTH' command wasn't working correctly with SQL auths (making Thunderbird fail), the same is true of the AUTHENTICATE command in IMAP. Again I have created a temp fix by commenting out the lines that check for that command in imap-login/client.c If I get some time tonight I will write a patch to fix this properly.

[Dovecot] "correct" permissions for login dir
by Kirill Miazine 09 Dec '04

09 Dec '04

I'm in process of moving away from Cyrus to Dovecot. I have my own authentication daemon working fine. It sets up two sockets: drwxr-x--- 2 root dovecot 512 Dec 7 21:07 /var/state/dovecot/login srw-rw-rw- 1 krot krot 0 Dec 7 21:07 /var/state/dovecot/login/sock drwx------ 2 krot wheel 512 Dec 7 21:07 /var/state/dovecot/master srw-rw-rw- 1 krot wheel 0 Dec 7 21:07 /var/state/dovecot/master/sock When I fire up Dovecot, it warns me of "incorrect" permissons for login dir (/var/state/dovecot/login) and "fixes" the problem. I want /var/state/dovecot/login to be owned by user krot (which the main daemon is running as), not by root. I suggest that login directory is not touched if external authentication is used. Socket are not wiped out, why should permissions be fixed? (see in master/master-settings.c around line 560). I'm afraid that some day I will forget to make this tiny change to Dovecot and end up with a mail system which does not work at all, because the master daemon won't be able to create dovecot/login socket. 1.0-test "works pretty well". Does it mean well enough to replace Cyrus (which indeed works pretty well)? I have maildir-based folders. Most users have no idea what IMAP is (my sister uses IMAP because I set it up, others just say that they don't need IMAP...) and they just download everything using POP3. Sometimes they use SquirrelMail. Default usage pattern. Are the risks high? Currently I have test56 on my test installation (which is almost ready to take over). Timo, Dovecot has been a pleasure to work with so far! -- They make a desert and call it peace. -- Tacitus

[Dovecot] 0.99.12 released
by Timo Sirainen 08 Dec '04

08 Dec '04

One change since -rc1 (the last one below). - Fix memory leaks in LDAP, MySQL and PGSQL userdb/passdb - Fix hanging when parsing mails that have over 4096 bytes in one line (SMTP servers normally don't allow over 1000 bytes so it shouldn't be much of a problem) - FETCH BODYSTRUCTURE sometimes gave a wrong reply (eg. with FETCH (BODYSTRUCTURE RFC822.SIZE) if it wasn't cached) - Never return more than one INBOX in LIST even if there are such files. They don't work anyway and it just confuses clients. - mbox: Don't allow creating INBOX directory by creating/renaming mailboxes under it. They just wouldn't work. - POP3: Don't return PLAIN in SASL list. We don't support initial SASL responses, so it only breaks with most clients that try to use it. - IMAP and POP3 login processes may have sent each line in two IP packets, one with the data and another with CR+LF. Some clients didn't work because of this.

Hi everyone, i just installed dovecot in Fedora Core release 1 (Yarrow). When accessing from a eudora 6.1 client, first it gave ssl authentication problems.

[Dovecot] dovecot 1.0-test-56 mail doesn't show up with Mac Entourage clients
by Will Bending 08 Dec '04

08 Dec '04

Hi. I'm seeing some issues where Entourage clients can see new mail, download it (or partially), but won't display the mail in the mailbox list. Mail shows up as having arrived, but never displays. These clients have worked in the past with versions of 0.99, but not in 1.0-test-56. I have dumped the connection traffic and it looks like Entourage aborts the IMAP session before it finishes fetching the mail. I have set up an IMAP server running test 56 and another running dovecot-0.99.11-1.1.fc3.rf and placed one email message in the inbox of a test account. The following is an error message I see in the 1.0 server's logs for some Entourage users experiencing this error, and is followed by a snippet of a tcpdump of the IMAP session on both machines showing where the Entourage client aborts the connection before completing the download of the message. Any help with or comments on this issue are greatly appreciated. Thanks, --will Error in dovecot.log from an Entourage client: dovecot: Dec 07 09:21:44 Error: IMAP(some_user): file mbox-lock.c: line 493 (mbox_lock): assertion failed: (lock_type == F_RDLCK ||

[Dovecot] Lost BODY message

DEBIAN package information: ii dovecot-common 0.99.11-3 ii dovecot-imapd 0.99.11-3 ii bogofilter 0.93.1-1 Apologies for cross-posting, but I think the problem lies somewhere in here. Maybe someone can tell me something useful. Now, I've confirmed the following: I received a mail message that was not spam, of size 2132 originally. clamav scanned it and bumped the size up to 2356 (added headers) ls -l shows it at 1019. The message file (maildir) does not show any BODY. I didn't have my procmail logging on VERBOSE=yes at this time which is a real bummer. Nothing else shows up in the syslog or other logs. As near as I can tell, the following happened: postfix delivered the email to the procmail script in good shape. Now, either procmail or dovecot got goofy on this one. I'm also running bogofilter in the dovecot script, but there's nothing in the procmail log to indicate a problem (logging would have helped!). But the bogofilter database doesn't show any signs of corruption. Somewhere between the interplay of procmail, bogofilter, dovecot things went wrong. I've increased all the logging that I can to watch for the next event. BTW - how can I increase the verbosity of dovecot while staying in daemon mode?

I'm sure you are right that this is where the problem lies. Unfortunately I don't know what the solution is. There is no "identity crisis" normally, as I ssh from one machine to the other with no problem, and eg keep a yum repository on the desktop which I use to update Fedora-3 on the small number of machines on my two little LANs (Ethernet and WiFi). I googled for this error "Server CommonName mismatch" and found dozens fo hits, but none of them seemed to suggest a concrete solution. What slightly puzzles me is that dozens of people must be using dovecot for more or less the purpose I envisage - otherwise what are they using it for - so my little problem must have arisen many times before. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

[Dovecot] Problem with dovecot on home LAN
by Timothy Murphy 08 Dec '04

08 Dec '04

At present I get email directly on my laptop in /var/spool/mail/* through uucp. I'd like to get the email in the same directory on my desktop (alfred), and then run a mail server on the destop and collect the email on my laptop (william) (or on other computers on my two little home LANs, ethernet and WiFi). I was advised that dovecot was a good imap server for this purpose (I tried cyrus-imapd, but decided it was too complicated), so I'm running dovecot on alfred (my desktop), with the following /etc/dovecot.conf (minus comments): ============================================ imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes ============================================ I am able to access my desktop with telnet from my laptop: ============================================ [tim@william ~]$ telnet alfred 143 Trying 192.168.1.1... Connected to alfred. Escape character is '^]'. * OK dovecot ready. x login tim <password> x OK Logged in. ^] telnet> quit Connection closed. ============================================ Unfortunately, neither fetchmail not KMail on my laptop seem able to retrieve mail from my desktop. With fetchmail I get the error message: ============================================ [tim@william ~]$ fetchmail alfred fetchmail: Server CommonName mismatch: localhost.localdomain != alfred fetchmail: Server CommonName mismatch: localhost.localdomain != alfred 10 messages for tim at alfred. reading message tim@alfred.murphy.ie:1 of 10 (765 header octets) fetchmail: fetchmail: getaddrinfo(localhost.smtp) fetchmail: SMTP connect to localhost failed fetchmail: SMTP transaction error while fetching from alfred fetchmail: Query status=10 (SMTP) ============================================ My .fetchmailrc on william reads ============================================ poll alfred proto IMAP user "tim" password "whatever" ============================================ I have no better luck trying to retrieve mail with KMail on the laptop, after adding the following entry to KMail=>Settings=>Configure KMail=>Network=>Receiving ============================================== Name: dovecot Login: tim Password: <password> Host: alfred Port: 143 Prefix to folders: /var/spool/mail/ ============================================== (I also tried with "Prefix to folders:" empty.) When I start KMail on william I get the message "Checking account dovecot for new mail", but no mail comes over, and I see no error in the log files on either machine (although I may have missed something there).

[Dovecot] imaps, certificate and authentification
by jean-Noël Chardron 07 Dec '04

07 Dec '04

hello, first sorry for my poor english I'm doing the migration from UW-imap to Dovecot I have two question about the authentification in the imaps (port 993) process In dovecot .conf I can enable (or disable) the différent port (pop, pops, imap, imaps) and may be restrict the access to the serveur with the ip adresse. Can I configure dovecot in imaps so it permit the access if the certificate is knowing by the server? Actually, this is the process to authenticate in WU-imap on imaps : the client connect to the server through a tunnel SSL (stunnel) and only if stunnel know the certificate, then the client can connect. and more, Is it possible when the client (with a certificate) connect to the serveur with imaps to authenticate the user without prompting the password, so the authentication is throught the certificate ? These are similar functionnality in the apache server with the restriction access to location et authentification with certificate. thanks -- Jean-Noel

[Dovecot] 0.99.12-1.1.fc1.rf broken?
by alex＠amcms.org 06 Dec '04

06 Dec '04

Hi, I dont know if this is a dovecot problem, or the rpm build, me, or my computer ;) Was wondering if anyone else has been having problems using the 0.99.12-1.1.fc1.rf release from http://dag.wieers.com/packages/dovecot/ My specific problem is this. 1. Dovecot starts 2. You can login using telnet 3. You can issue a select inbox but nothing seems to happen By this stage dovecot is spiraling out of control, using up almost all my tiny cpu's processor, when usually it uses basically nothing. What appears to happen if you look at the logs is this. ======= Dovecot Log ======= dovecot: Dec 06 10:39:48 Error: login: Authentication process 5634 doesn't exist ======= Dovecot Info Log ======= imap-login: Dec 06 12:36:09 Info: Disconnected: Inactivity [127.0.0.1] Then, I noticed that if I tried to log in again I would have multiple dovecot-auth processes churning away at my processor.... I went thru the config file, and the new one with my changes, still the same. I also restarted dovecot several times, having to kill all the processes manually as service dovecot stop didnt seem to work. Is anyone else having this problem? And do they know how to fix it? Im running dovecot on fedora core 1, using mysql for authenticating. Thanks Alex

[Dovecot] problem with test56
by Cor Bosman 06 Dec '04

06 Dec '04

Hi all, im doing some tests with the test56 release and im seeing some problems with APPEND (may be related to something else, I just see it with APPEND). When I ask someone to move some emails from one mailbox to another, after some messages (seemingly random), the client experiences a 'hang'. When tracing the process what seems to happen is that dovecot doesnt send a final OK after that specific email. It's kinda hard to attach a gdb at that point, so for now, maybe someone has seen this also? Cor

[Dovecot] IMAP - many folders?
by piotr＠mallorn.ii.uj.edu.pl 05 Dec '04

05 Dec '04

Hi, I've been reading the list and it seems the answer to my (soon to be asked question) is no, at least with 0.99, but I'll ask to be sure. I have following setup: new mail goes to ~/Mail/Maildir, except for mailing lists which are moved by procmail to ~/Mail/mailing_lists/name, spam which goes to ~/Mail/spam. Read mail is moved by mutt to ~/Mail/read. Everything is in maildir format. Is it possibile to configure dovecot in such a way to allow user to access all those mail folders thorough imap/pop? User can access ~/Mail/Maildir by setting default_mail_env, but so far nothing else. -- Piotrek irc: #debian.pl Mors Drosophilis melanogastribus!

http://dovecot.org/rc/ Just gathered the patches in dovecot.org/patches/ and a few more that I think have been sent to this list before. If there's anything missing, please tell. - Fix memory leaks in LDAP, MySQL and PGSQL userdb/passdb - Fix hanging when parsing mails that have over 4096 bytes in one line (SMTP servers normally don't allow over 1000 bytes so it shouldn't be much of a problem) - FETCH BODYSTRUCTURE sometimes giving a wrong reply (eg. with FETCH (BODYSTRUCTURE RFC822.SIZE) if it wasn't cached) - Never return more than one INBOX in LIST even if there are such files. They don't work anyway and it just confuses clients. - mbox: Don't allow creating INBOX directory by creating/renaming mailboxes under it. They just wouldn't work. - POP3: Don't return PLAIN in SASL list. We don't support initial SASL responses, so it only breaks with most clients that try to use it.

[Dovecot] newbie question

Hello all, just managed to install dovecot as imap server on a Suse Linux box. Now running fine with mbox format. A question regarding maildir or mbox. The MDA (in my case sendmail, Mlocal = procmail) stores mbox format. Do have to modify the local mailer to store maildir format or does dovecot convert automatically from mbox when I tell dovecot to use maildir format? Thanks, for any hint. Carsten

[Dovecot] Maildir/mbox on a per-user basis

Hello, The Wiki indicates that Dovecot can do either mbox or Maildir on a per-user basis: default_mail_env can be overridden in userdb for each user.

[Dovecot] master or client
by Kirill Miazine 03 Dec '04

03 Dec '04

Hello, Dovecot auth protocol 1.0 defines differend command sets for client and master. How can a daemon distinguish a master connection from a client connection? Clients do send CPID and master does not. I have following auth configuration: auth external { socket connect { master { path = /var/state/dovecot/login/master-auth } } } I try to learn my authentication daemon to learn to speak with Dovecot. I fire up my master.py and try to login via pop3 as foo:bar. Below is what my master.py receives from Dovecot (master and client), VERSION commands are not shown: km@thinkpad:/home/km > ./krot/sbin/master.py CPID : ['11915'] CPID : ['11915'] CPID : ['16652'] CPID : ['11915'] AUTH : ['1', 'PLAIN', 'service=POP3', 'secured', 'lip=127.0.0.1', 'rip=127.0.0.1', 'resp=AGZvbwBiYXI='] REQUEST : ['9', '11915', '1'] CPID : ['16652'] (In the above output command and parameters are parsed.) The protocol specification is mentioning a separate SERVICE command in the client's greeting. I can't let my daemon die if the master issues DIE. Why should a server exit when it receives DIE? Can anybody provide an example dialog of an authentication request that is successful and a reques that fails because of a bad password.

[Dovecot] pop3 with lmos results in multiple downloads
by Juerd 03 Dec '04

03 Dec '04

One of our users wants to use POP3 with leave-mail-on-server (LMOS). That's great and works well for most people. But for some reason, they MUA (outlook) downloads messages more than once. As the MUA asks for messages, I'm sure it's Outlook's fault, but I was wondering if there is anything that can be done about this on the servern side, or if anyone knows how to fix Outlook. I'm sending this here, because they report that with non-dovecot servers it does work correctly. They do not want IMAP, because they want to use Outlook, which cannot support both Exchange and IMAP simultaneously. This user has multiple accounts, and only for some of them things go wrong. A temporary fix is to remove the mail from the server once, but after a few more messages arrive, the problem starts all over again. Please help. Regards, Juerd

[Dovecot] Problem getting incoming mail to IMAP inbox
by Jeff Sutherland 03 Dec '04

03 Dec '04

I have dovecot-0.99.10.5 on Fedora Core 2 installed and otherwise operating using Maildir format for the folders, Kmail as the email client. Got through all the ssl and other security configuration fine, but have one last problem: I can't read the incoming mail from /var/spool/mail/%u. Tried several 'default_mail_env' settings, including none at all, to no avail. When I try to check in new mail to the inbox, the only messages are "Transmission Complete, no new messages" Tried this setting for example: default_mail_env = maildir:~/Maildir/:INBOX=/var/spool/mail/%u but to no avail. Is something getting cocked up because the folders are all in maildir format and the incoming mail spool is in mbox format? I checked permissions, they seem ok. Kmail can pull the messages in just fine to its local folder inbox, it just seems that dovecot can't read the mail spool file for some reason. All the other maildir folders work fine. ?????????

[Dovecot] Cannot list mailbox

Hi, I have dovecot 0.99.11 on a Linux machine running against a maildir based mailbox. I am getting the following errors in the maillog: Nov 27 23:08:14 fawad3 imap(fawad): file imap-bodystructure.c: line 278 (part_parse_headers): assertion failed: (part->physical_pos >= input->v_offset - start_offset) Nov 27 23:08:14 fawad3 dovecot: child 14202 (imap) killed with signal 6 This happens when the mail reader tries to enumerate the messages in the INBOX. I am able to read the messages whose headers have already been cached by the mail reader. It is also able to read others folders without any problem. This problem has occured before, and I was able to get rid of it by identifying the junk mail message it was dying on. In this case, however, I'm not able to figure out which message is causing it to crash. I am able to read the same maildir in mutt, and Courier IMAP doesn't seem to have trouble with it either. I'd really appreciate if someone could tell me what I can do to get around this problem. Regards -fawad

I'm running with mmap_disabled=yes, mbox format. Most of the 1.0-test builds I have done eventually corrupt their index files, and show strange behavior (click on a message in the folder view, and an entirely different message opens... delete three or four messages and expunge, the messages instantly reappear as unseen.). I typically wipe the .imap directories between different builds of Dovecot. I've been following the -test code for a couple of months now, just to see how it does, because we're running UW IMAPd and are excited to have a way to increase the performance of our mail cluster (indexes) without having to move away from mbox. Let me know if there's more information I could provide that would be helpful. Jim

[Dovecot] Excessive imap_login processes
by Keith Edmunds 02 Dec '04

02 Dec '04

I'm running Dovecot on a very small mail server (never more than six users accessing IMAP, often fewer). I'm seeing the number of imap_login processes grow over time, and right now there are 23. All the "login_process_*" settings in dovecot.conf are commented (ie, at their defaults). Is this a known or expected issue? The version of Dovecot is 0.99.10.8, which I accept is perhaps a little old. Thanks, Keith

[Dovecot] Entourage on Dovecot 09.11, is 1.0-test the answer?

Background: I'm running a RH9 box with Dovecot 0.99.11. Dovecot was installed using yum and the rpm found on http://dag.wieers.com/packages/dovecot/. With two exceptions I've been enormously happy with Dovecot. I'm even happier having recently successfully installed pop-before-smtp sop one exception down. However the other problem I've experienced is becoming critical. I've an ongoing issue with MS Entourage clients, a MS for Mac product, unable to authenticate to Dovecot. This had been attributed to MacOS 9/MS Entourage 2001 but with new systems in place I'm having the same issue with MacOS X/MS Entourage 2004 being unable to authenticate to Dovecot. MS acknowledges the issue in http://support.microsoft.com/kb/871016 with the errata: > 5 Known issues > 5.1 NTLM v1 authentication support > Entourage no longer supports NTLM v1 authentication. Entourage does support NTLM v2. Where I am now: There has been previous references to an Entourage authentication issue on the mailing list but it was resolved by "after I tried everything else with no success, upgrading from Dovecot 0.99.10.2 to 0.99.10.4 solved the problem." Well, I'm at 0.99.11 so apparently this is back, or something else is going on. >From several hours going over the mailing list it appears that Dovecot 1.0-test is the solution with it's extended NTLM support. However I'm not a very sophisticated sysadmin and so it was with trepidation I downloaded dovecot-1.0-test52 and started following the instructions. After a quick "yum install openssl-development" I thought I was good to go but alas "./configure --with-ssl=openssl" resulted in: > ./configure: line 26374: pkg-config: command not found > checking for SSL_read in -lssl... yes > checking openssl/ssl.h usability... no > checking openssl/ssl.h presence... no > checking for openssl/ssl.h... no > checking openssl/err.h usability... yes > checking openssl/err.h presence... yes > checking for openssl/err.h... Yes and make failed with a cascade of errors after: > In file included from /usr/include/openssl/ssl.h:179, > from ssl-proxy-openssl.c:14: > /usr/include/openssl/kssl.h:72:18: krb5.h: No such file or directory Why I'm posting: So, hoping I've given enough detail to be useful, here are my questions: * Am I correct that MS Entourage 2004 can't authenticate with Dovecot .99.11? Are there folks it does work for (how)? * Am I correct that Dovecot-1.0-test has support for NTLMv2 and would thus authenticate MS Entourage 2004? * Does anyone have a prebuilt (yum suitable) rpm of a recent Dovecot 1.0-test for RH9? Dag appears to only carry released versions, is there a source for -test ones? * Is there something trivial I'm overlooking in trying to build dovecot-1.0-test52? I'm assuming I'm missing /usr/include/openssl/kssl.h, is this correct? Any assistance is greatly appreciated. I was pushing my skillset getting pop-before-smtp working. While I'm good at following directions and learning from them I'm just that; learning. -- Michael <michael(a)michaelmaggard.com>

[Dovecot] 1.0-test53, sig11 when sorting by thread
by Nicolas.Kowalski＠imag.fr 30 Nov '04

30 Nov '04

Hello. When trying to sort a folder by thread (with pine4.61), I get a sig11. The mailstore is Maildir, indexes stored in /var/indexes/%u. The syslog on the server shows this: Nov 29 11:37:55 olan dovecot: IMAP(kowalski): Corrupted index cache file /var/indexes/kowalski/.INBOX/dovecot.index.cache: record points outside file Nov 29 11:37:56 olan dovecot: child 14344 (imap) killed with signal 11 A backtrace of the core is attached. Thanks. PS: I tried with mbox mailstore, and got the same sig11. -- Nicolas

[Dovecot] test53 and signal 11 errors
by Sean Porter 30 Nov '04

30 Nov '04

I installed test53 tonight, and I've begun to see the following error in my maillog every time I attempt to retrieve mail from an imap client: dovecot: child 46128 (imap) killed with signal 11 I built from source on FreeBSD 4.9 with the following: ./configure --with-mysql --with-storages=maildir --with-ssl=openssl A little bit of Googling seems to indicate that this is a hardware issue(http://www.bitwizard.nl/sig11/), but I've not had this error under any other circumstances. What other information would be helpful to sort this out?

[Dovecot] 1.0-test53
by Timo Sirainen 29 Nov '04

29 Nov '04

http://dovecot.org/test/ Sorry for not answering any questions for past two weeks, I'll try to get around answering them in next few days. I've also been thinking about if I should switch from CVS to Darcs. It seems to be exactly the kind of reversion control tool I had wanted to use. Anyone have comments for or against it? I'd still have read-only CVS repository generated from it, although I couldn't yet find a way to do it. Anyway, test53: - Recent flag counters should finally be correct - dovecot-shared file actually works correctly now - Cache file works with mmap_disable = yes (still some small issues though) - Lots of internal changes in indexing code, especially for mmap_disable = yes - DIGEST-MD5 authentication works again - etc. It's been running with me for 45mins without breaking. Guess it should work. :)

[Dovecot] Orientation and configuration help
by J Moore 29 Nov '04

29 Nov '04

This sounds to me like a "RTFM" question, but I've read the Wiki, and looked through the m.l. archives as far back as July... I still don't have a clear answer, so I'm posting here :/ I'm currently using mutt as my mail client. It runs on the same host that runs the sendmail MTA for my domain. So sendmail "delivers" my mail to /var/mail/<username>, and I read it from that location w/ mutt, transferring the "new" mail to a folder in my home directory if I want to save it (/home/<username>/Mail/<foldername>). This arrangement has been convenient, useful and reasonably secure (I think): I can check mail from anywhere via SSH, and I don't have to worry about downloading virus-laden spam/shit to my Windoze (corporate) laptop. Now, I want to change; I want to use dovecot to provide IMAP access to my mail. I'd like to do this in such a way that I can still access mail using mutt when I want/need to do so. I've installed dovecot, and reviewed /etc/dovecot.conf. I think I need to do the following to get underway: 1) create a directory for Maildir-formatted folders: mkdir /home/<username>/Maildir 2) start the dovecot daemon Is that it? Will dovecot "take over" from mutt, and put mail in my home directory? Or do I need to configure sendmail to deliver to dovecot? Also, there are other users/email accounts on the mail server that I would like to leave "as-is". Over time, I may want to migrate them to dovecot as well, but I'm reluctant to switch everything over until I've had a chance to evaluate it. Should I run dovecot as a "rootless" installation to get it for a single user, or should I just set my single UID in dovecot.conf? Thanks, Jay

[Dovecot] Which is the imap root directory? Conflicting documentation...
by Tom 29 Nov '04

29 Nov '04

So, which is the imap root directory? I am getting conflicting definitions from the documentation (copied below)... ------------------------ mbox storage requires detecting INBOX location and IMAP root directory. If MAIL environment points to file (+rw) it's treated as the INBOX file. If it points to directory (+rwx) which contains .imap/ (+rwx), inbox (+rw) or mbox (+rw) it's treated as IMAP root directory. If INBOX isn't known, imap_root/inbox file is used by default. If root directory isn't known, we try to find it from /, ~/mail or ~/Mail. Files created by Dovecot ------------------------ .subscriptions: One folder per line listing subscribed IMAP folders. There's only one of these files in the root mail directory (~/Maildir/ or ~/mail/.imap/). ---------------------------------------------------------------------------- ------ My .subscription file is located in ~/mail/ but the documentation states only one should be in ~/mail/.imap/ !!!! Thanks, OOOrah

[Dovecot] SASL authentication
by Tom Allison 29 Nov '04

29 Nov '04

I was browsing the wiki and found a section on what appears to be as close to "exactly what I'm looking for" as I've seen in a long time. http://wiki.dovecot.org/moin.cgi/DovecotPostgresql However, I'm not inclined to do very much "blind" configuration on my machines without first understanding the what/why of it all. My theory is that this helps me with the RTFM syndromes later. Hopefully. My current dovecot installation is based on pgsql authentication with a single domain and files being placed in a $HOME. It's as if it were /etc/passwd based, but the passwords are different. I would very much like to migrate this into a system which supports multiple domains and this Wiki seems to be the best means for that. However, I didn't use SASL authentication. I was emotionally scarred trying to use SASL with a venture with Cyrus-IMAP under different circumstances. Could someone explain why SASL is a good thing in this case? Does it allow for something more, lead into future developements? Most of the rest of this general paper I do understand, but the SASL is the only part where I'm not sure if I must do that, want to do that, or can live without it.

[Dovecot] NFS, test52, maildir, freebsd 4.x and OS X (Panther) Server
by Sean Porter 29 Nov '04

29 Nov '04

I've been working on setting up a Dovecot server with a maildir mailboxes stored over NFS. Initially, everything was working great, and then I started seeing this error as previously discussed on the list in my maillog: (mail_index_expunge): assertion failed: (!t->view->external) Timo, in another thread, suggested to remove line 247 in mail-index-transaction.c in the test52 source, which I blithely ignored as I thought this would remove only the error message from the logfile and not fix the problem. At Mark Lidstone's helpful off-list insistence I did remove the line, recompile, and everything did seem to be working, until I encountered a different error. I started doing some light load testing from multiple clients (essentially, clicking like a rabid monkey on Get Mail in Thunderbird and hitting different mailbox links in Squirrelmail as the same user) and started running into this error in the logs: Nov 22 20:10:46 server dovecot: IMAP(mailuser(a)example.com): rename(/host/mail/mailboxes/mailuser(a)example.com/dovecot-uidlist.lock, /host/mail/mailboxes/mailuser(a)example.com/dovecot-uidlist) failed: Input/output error Nov 22 20:10:46 server dovecot: IMAP(mailuser(a)example.com): file_dotlock_replace(/host/mail/mailboxes/mailuser(a)example.com/dovecot- uidlist) failed: Input/output error Oddly, the dovecot-uidlist.lock file was unremovable on the NFS server (OS X Panther Server) with a simple 'rm', so I started digging into things a little further. It seems that the OS X NFS code is based on the FreeBSD 5.x codebase. The server that Dovecot (and my NFS client) lives on is FreeBSD 4.x, which doesn't support NFS locking at all(incidentally, the FreeBSD NFS Server is apparently incompatible with Linux NFS clients as well -- nice!). Per the suggestion in http://www.dovecot.org/doc/nfs.txt I'd already been storing my index files locally, but it appeared that the control files were somehow blowing up, even with NFS-safe dotlocking. All hope was nearly lost when I came across this tidbit in a post from Timo(http://www.dovecot.org/list/dovecot/2003-May/001489.html): - :CONTROL=dir in default_mail_env can specify where to save dovecot-uidlist and .customflags files. Useful for above problems. I then changed my dovecot.conf to retreive the mailboxes from the NFS mount, but store the indexes and the control files locally: default_mail_env = maildir:/host/mail/mailboxes/%u:INDEX=/home/dovecot/%u/indexes: CONTROL=/home/dovecot/%u/control All seems well so far. I know this is a relatively unique setup, but I thought it might help some of the other people that are running into NFS-related issues. Suggestion: perhaps the :CONTROL directive could be added to mail-storages.txt or dovecot-example.conf? A hint may also want to be added to http://www.dovecot.org/doc/nfs.txt. Sean

[Dovecot] AppleMail causes dovecot error: file mbox-rewrite.c: line 429 assertion failed

I get the following error message in my syslog frequently when a user accesses the dovecot (IMAP) server from his OS X AppleMail client: Nov 24 09:45:42 myhost imap(someuser): file mbox-rewrite.c: line 429 (mbox_write_header): assertion failed: (hdr_parsed_size.physical_size == hdr_size) Nov 24 09:45:42 myhost dovecot: child 23277 (imap) killed with signal 6 Usually each message appears 5-6 times. The user on the other end doesn't notice any problems. Any idea why this occurs and what I can do to prevent it? I'm using dovecot from Debian sid, 0.99.11-3.

[Dovecot] Runtime root directory
by Brad Robel-Forrest 29 Nov '04

29 Nov '04

I'm considering modifying the Dovecot source to support a runtime designation for the root directory instead of relying on the prefix provided via configure. Once complete, it would be possible to move the root directory around somewhat ad-hoc after installation without having to rebuild the source. The primary driver for this is that I'd like to wrap a binary build of Dovecot within an OSX application bundle. These bundles can be placed anywhere the user desires, so Dovecot couldn't rely on a particular build-defined root directory. Before I get too far down the path, I'd like to know if there's a desire for this type of enhancement. If so, I'd like to provide a diff that would meet any other requirements for this change. There are two methods I was considering. Feel free to suggest a better alternative as I'm not ecstatic about either at the moment. 1. Find and change all uses of the prefix directory to instead prepend a value obtained from the environment (say, DOVECOT_ROOT_DIR). 2. Find and change all uses of the prefix directory to instead prepend a value obtained from the configuration file (say, a new setting called "dovecot_root_dir"). In either case, if the value was not available or not a valid directory, I would fall back to the build prefix. I would also make this functionality optional via configure--defaulted "off". -brad

[Dovecot] Dovecot 1.0-test52 and LDAP authentication
by Jonathan Salomon 26 Nov '04

26 Nov '04

Hi all! I have upgraded Dovecot 0.99.11 installation that's worked with LDAP to Dovecot 1.0-test52 and I can't get LDAP to work. I noticed the /etc/dovecot.conf is slightly different, so I have adjusted changes. If I use the standard auth (passw & pam) everything works fine, however when I user ldap for auth Dovecot starts but then dies: dovecot: Nov 26 14:14:36 Error: Auth process died too early - shutting down dovecot: Nov 26 14:14:36 Error: child 16454 (auth) killed with signal 11 As far as I can tell the /etc/dovecot-ldap.conf hasn't changed since 0.99.11 and the LDAP server is working properly. What is happening here? I did a 'strace -f dovecot 2>log' because I saw this in the mailing list archive, but it doesn't really tell me anything, so I have someone can tell me what is happening here. I have included the tail below. Thank you in advance!

[Dovecot] [OT] Apple Mail.app access to localhost imap when no network
by Alan Schmitt 25 Nov '04

25 Nov '04

Hello, Sorry for the offtopic subject, but I tried asking this on some Apple mailing lists and could not find an answer there, and as it's related to imap (provided by dovecot), someone might know something about this. The problem is the following: I have a local IMAP server provided by dovecot, so that I can store my mail in maildir format, and read it both using mutt and Apple Mail.app. Mail.app is configured to access localhost:143 to access mail. However, I discovered that when there is no network connection (no ethernet cable plugged in and no wifi network), Mail.app is saying that it's working in disconnected mode and refuses to access the imap server. Would someone have a suggestion as to what to do to allow connected access to localhost when no network is present? I'm very new to OS X (I come from Linux). Thanks a lot, Alan Schmitt

[Dovecot] Cannot see contents of ~/mail folder
by Saurabh Barve 25 Nov '04

25 Nov '04

Hi, I just installed dovecot-0.99 on my Fedora Core 2 machine. When I start the secure IMAP daemon, I am able to see my Inbox, but not the other folders in the 'mail' folder in my home directory (sent-mail, saved-messages, etc.) These folders were created when I was using pine earlier on the machine. In my dovecot.conf file, I have set: default_mail_env = mbox:~/mail:INBOX=/var/mail/%u I am using Mozilla Mail as my mail client, if that makes a difference. Dovecot seems to be creating a directory called .imap inside the 'mail' folder, where it is storing the inbox and a Trash folder. I have set "mail_full_filesystem_access = no" so that users don't access any of their other files except the mail folder. From what I understand, I don't have to set IMAP path in Mozilla Mail. I tried doing that too, just to try it out, but as expected, it didn't work. What do I need to set in order to see my other folders in the 'mail' directory?

[Dovecot] ssl_ca_file
by Jacob Elder 25 Nov '04

25 Nov '04

I am very fond of Dovecot, but it would be nice to have a more useful SSL implementation. When do you think we'll see a non-beta version that supports ssl_ca_file? I am running 0.99.11-3 from Debian testing. -- Jacob Elder

[Dovecot] Error in IMAP command GETACL: Unknown command..
by Ingo Lantschner (Lists) 24 Nov '04

24 Nov '04

Hi all, I have just installed dovecot on my Fedora Core 2 box. I would like to use it only for reading archived email from within my Mozilla 1.7.3. I syminked my old opera-files (*.mbs whoch seems to be same as mbox) into ~/mail. Seems to work fine, mostly I can open the mailfiles - sometimes it hangs with the following error: The current command did not succeed. The mailserver responded: Error in IMAP command GETACL: Unknown command.. And then: The current command did not succeed. The mailserver responded: Error in IMAP command MYRIGHTS: Unknown command.. ALthough I searched in Google and in the Wiki on dovecot, I did not find any hint - am I the first with this problem? TIA Ingo. -- Ingo Lantschner T (+43-1) 59 55 766 M (+43-664) 143 84 18 -- Ingo Lantschner T (+43-1) 59 55 766 M (+43-664) 143 84 18

"localhost" does resolve (I tried to ping it, and it worked), and 127.0.0.1 does not change anything. So I guess my initial guess was wrong, and Mail must be trying to see if the network is up before even trying to log in. Alan Schmitt

[Dovecot] .INBOX required?
by Todd Slater 20 Nov '04

20 Nov '04

Hi, Newbie to Dovecot and IMAP in general. The system in question is RH 9, Dovecot 0.99.11, Maildir, accessing mail with SquirrelMail, Thunderbird, Kmail, Mutt, Entourage and Mail.app. I've set up the maildir for users in ~/Maildir. Inside that I have other folders, .Sent, .Drafts, .Trash, .Junk, .MakeJunk, .MakeGood. ~/Maildir itself has the cur, new, and tmp folders, but I note that there is also an .INBOX folder. Mail to the account does end up in ~/Maildir/new and it's readable in the various MUA's (as Inbox). I'm just not certain why the .INBOX is there, and if I'm supposed to be creating the other folders as .INBOX.otherfolder. Thanks, Todd

[Dovecot] [PATCH] add initial response support for NTLM and RPA
by Andrey Panin 19 Nov '04

19 Nov '04

Hello, this patch adds initial response support for NTLM and RPA authentication mechanism. It can be useful if dovecot acts as authentication backend for SMTP server. RFC2554 permits initial response in AUTH command, so it's legal to send NTLM type 1 message or RPA token 1 in it. Please consider applying. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

[Dovecot] noob - Outlook Duplicate Problem Question
by Jeff Ramsey 17 Nov '04

17 Nov '04

Hi, I use dovecot 0.99-11 with sendmail latest, and clamav-milter, and spamass-milter. Whole setup works great. We only use dovecot for pop3, no imap. We use primarily Outlook 2000-2003 for a client. I have a couple of users who prefer to leave a copy of each message on the server. I read the archives about the Outlook Duplicate Message problem regarding the setting 'Leave a copy on the Server'. I read that someone fixed this by changing the order of the UIDL from datestamp.message# to message#.datestamp. My question is if I make that change in my source for 0.99-11, will the 1.0 version have a fix for this included, or should I look for another pop3 server? I'd like to continue to use dovecot as it is very light and fast, but I'm trying to eliminate using source compiled binaries on my production servers, and letting YUM do my updates for me. I can compile this version from source, using the fix that was mentioned in the September Archives for this list, if I know that the problem (which is an MS problem, go figure) will be gone in future RPM binary packages. Thanks for any info or help. Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] 1.0-test52
by Timo Sirainen 16 Nov '04

16 Nov '04

http://dovecot.org/test/ I have very high hopes that mbox support is finally stable in this version. I've been running some stress tests for an hour now without it breaking (well, there are two potential problems but I think they were just fixing previous breakages). Before it took only a few minutes at most to break. - fixes several mbox syncing problems, especially expunges potentially deleted parts of wrong messages - maildir: readdir() race conditions are fixed by keeping dovecot-uidlist lock a bit more than before (it really doesn't matter in most cases, we did this before as well but slightly less often. so this really fixes just the problematic cases without giving hardly any more overhead than there was before) - index header changed a bit. will rebuild indexes and print some cache indexid errors.. i should hide these errors too.. - fixed memory leaks in dovecot-auth

[Dovecot] dovecot and outlook express and large messages
by Daniel 16 Nov '04

16 Nov '04

Hi I have been using Dovecot 0.99.11 and 1.0-test52 on a server with about 2000 accounts. All has been working good until a few days ago. Now I'm stuck and can't work out whats going on. The problem seems to be only with Outlook/outlook express clients. If the mail is large with an attachment its fails. After you hit the send and receive button after a while Outlook express gives the error "Your POP3 server has not responded in 60 seconds". Network activity seem to be minimal between the client and the server. There is no log entry out of the ordinary to say what went wrong. I have tried out a number of changes to the dovecot.conf file, none make any difference. Thanks for any help. Regards Daniel Rowe

[Dovecot] eudora issue
by kent crispin 16 Nov '04

16 Nov '04

There seems to be a protocol mismatch between eudora and dovecot when using pop. The login interchange with, for example, mozilla, is as follows: MO: [connects] DC: +OK dovecot ready. MO: CAPA DC: +OK DC: CAPA DC: TOP DC: USER DC: UIDL DC: RESP-CODES DC: STLS DC: SASL PLAIN DC: . MO: USER yyy DC: +OK MO: PASS xxxxxxxx DC: +OK Logged in. But with eudora, with apparently equivalent configuration, the sequence is as follows: EU: [connects] DC: +OK dovecot ready. EU: CAPA DC: +OK DC: CAPA DC: TOP DC: USER DC: UIDL DC: RESP-CODES DC: STLS DC: SASL PLAIN DC: . EU: auth PLAIN AG1tcgBtaXN0bGV0b2U= DC: -ERR Unsupported authentication mechanism. At this point eudora reports an error back to the user, and the connection fails. Can anyone shed any light on this? Is it just that there is an incompatibility in how eudora and dovecot view the protocol? Or is there some configuration option I need to tweak to make things work? Thanks for any help.

[Dovecot] RE: dovecot and outlook express and large messages
by Daniel 16 Nov '04

16 Nov '04

Hi Dose dovecot have problem working on a eth0:1 alias type interfaces? I just wondering if this could be my problem? Dovecot would do the authentication correctly and send small email but as soon as any load was put on it like downloading a mail with a large attachment it would fail. All network traffic would stop. No errors in the logs. As soon as I move the service to listen on a non alias interface eth0 all works fine. Very strange. I have taken a good look at our server to check that is not anything. I'm pretty sure we are good. I have also rebooted the box to see if that would fixed it which it didn't. Regards Daniel

[Dovecot] dovecot with different POP3S / IMAPS Certs
by Vincent Jaussaud 15 Nov '04

15 Nov '04

Hi, I'm new to dovecot, but actually planning to switch a wide WU-IMAP/POP installation to dovecot. With WU-IMAP, a different certificate can be used by pop3s and imaps, allowing both server to be reachable through different hostnames,without SSL complaints on the client side; this is mostly used for scalability. I'm trying to do the same thing with dovecot; that is having dovecot using a different certificate for it's pop3s instance and imaps instance. Unfortunately, in dovecot configuration file, only one certificate can be set; used by both pop3s / imaps. Any idea of the best way to handle this ? Thanks !

[Dovecot] dovecot-auth leaves zombies
by Stefano Maffulli 15 Nov '04

15 Nov '04

Hi all, I have installed and configured dovecot on two different machines, so I don't have much experience with this server. One installation is giving me serious problems, that I have a hard time tracing. From the beginning: the machine is a debian mix (stable/unstable) dovecot 0.9.11, real users authenticated via pam_ldap/nss_ldap. It serves ~70 users, all of them using Outlook, Outlook Express and IMP. The system seems to work just fine for a while, but after a some time, some dovecot-auth zombies start appearing. I can't really understand who/what is causing them. The only thing I see in the logs are these lines, very sporadically, but I still couldn't trace when they happened. Nov 5 09:40:28 csv-mail-01 dovecot-auth: nss_ldap: reconnecting to LDAP server... Nov 5 09:40:28 csv-mail-01 dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) (BTW, also apache2 sends similar messages, I don't know if they are related) Nov 5 09:52:14 csv-mail-01 apache2: nss_ldap: reconnecting to LDAP server... Nov 5 09:52:14 csv-mail-01 apache2: nss_ldap: reconnected to LDAP server after 1 attempt(s) After a while dovecot stops authenticating and needs to be killed and restarted (/etc/init.d/dovecot stop takes some time to actually stop dovecot processes). Do you have any clue of what is going on and where I can investigate further? I would like to say 'it's Outlook's fault', but I really can't. Any hint appreciated. regards stef

Hi list, Just jumped providers and am now desperately trying to get IMAP running on a new server... But not getting the link between postfix and dovecot working. :-( My two problems are: 1) local mail seems to get into the ~/Maildirs, but not from the outside (this is a postfix issue?) 2) I cannot find information on how to tell postfix to use virtual domains/addresses and then connect dovecot to them (as they are now in non-standard locations and/or formats) I'm sure this is a FAQ, but cannot find an example that would walk me though this. Can someone kindly point me in the right direction? -- Mitch

[Dovecot] Excessive imap-login and pop3-login processes
by Ben Beuchler 08 Nov '04

08 Nov '04

I'm running a Linux mail server with Postfix and Dovecot. I've noticed that the number of "imap-login" processes usually sits around 240, and "pop3-login" usually around 50 or so. The comments in the config file seem to indicate that, with my setup, I shouldn't see more than about 10 of each. Am I misunderstanding the config or is this expected behavior? login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_logging_users = 256 The mail server receives about 1.5 - 3 logins per second and usually has around 75 simultaneous IMAP sessions. There are rarely more than 1 or 2 simultaneous POP3 sessions open. Thanks... -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix
