[Dovecot] mail not found
by Michael Collins 27 Sep '05

This is in my dovecot.conf default_mail_env = maildir:/var/mail/vhosts/%1u/%u/ my mail ia in/var/mail/vhosts/anawebdesigns.com/user1/cur, new, tmp As you can guess these are virtual accounts. Auth works but mail is not found. How do I need to modify the line in dovecot.conf? Thanks. -- -- Michael H. Collins It's us against them. Ride like you stole it. If you love some code, set it free.

But I found that I must add the mail=mbox:/var/spool/virtual/%d/%n part. Without this part, the dovecot seems not checking the right location of mail spool and simply say that "no new email". Now I added this part together with "home=/tmp" part into userdb config and It works now with IMAP folder in /tmp directory. But I want to ask if there is any file locking problem as I am running virtual email with vmail as owner for all mbox accounts. And it seems that they are all share the same IMAP folder located in /tmp directory.

[Dovecot] Hostname passed to PAM as rhost
by Tom Alsberg 27 Sep '05

27 Sep '05

(I am sorry to bother the list with something I should have verified myself right now - I simply do not have access to the source code here) Thinking of some limit I wanted to put with authentication, I am wondering - when Dovecot authenticates a user using PAM, now that (in 1.0) it passes the rhost item to PAM, it passes a hostname, not an IP address. Does it double-verify the DNS record before it trusts this to be the hostname (first checking the IP address in in_addr.arpa and then checking that the hostname indeed maps back to the same IP address)? That is necessary in order to trust the client address when determining authentication strength in the PAM module based on the client location (specifically we want stronger authentication when the client comes outside of our network, while inside a plain password suffices), as else anybody could "spoof" the hostname by changing the IN PTR record of his IP address to point back to some "trusted" hostname (given he has control of the DNS zone his host is in, which is completely possible given the server knows nothing about it).

[Dovecot] POP3 problem
by michal 27 Sep '05

27 Sep '05

Hey all this is my first post to this list. I have fresh Red Hat AS 4.0 with postfix 2.1. This will be my mail server. I have one problem with pop3. My mail server is working properly. I did the following test: Sent an email to some other server(yahoo.com)->email got there fine. >From that other server(yahoo.com) replaied-> to the new server and email got there fine,checked using pine. Now in x windows on the mail server if i lunch email client software and set up the account, then i can send and receive emails fine so pop3 is working. But when i go to different machine like PC set up outlook then i cannot receive emails. I get error in outlook that the connection has failed. So i telnet 192.168.1.10 110 and I have gotten response from the server 250 dovecot OK. I really dont what to do at this time. I have been trying couple different things without any luck..... need some help? Mike

[Dovecot] How safe is mbox_very_dirty_syncs?
by Chris Wakelin 27 Sep '05

27 Sep '05

I've tried turning on mbox_very_dirty_syncs for myself (and a few other brave souls running 1.0-alpha3 rather than 1.0-stable) again to see what perfomance gain it gives (see thread http://www.dovecot.org/list/dovecot/2005-July/007956.html) Now we aren't running UW-IMAP at all, how safe is mbox_very_dirty_syncs assuming the only other process writing to mailboxes is our MTA (exim) which simply appends messages to the end? Is it safer still using Dovecot 1.0-alphas and the LDA? Does it matter if there are concurrent connections to the mailbox?

[Dovecot] new mailbox format v2
by Timo Sirainen 27 Sep '05

27 Sep '05

Updated version. The previous one was a bit too complicated with flag updates for pretty minimal benefits. Changes: - writing/reading mail flags can be disabled to get better performance without it requiring any changes to how the files are normally handled (so mixed more works fine). - writing flags now requires getting shared locks. so there's the overhead of locking but flag writers don't have to wait for each others. - reading requires no locking anymore. the comment in the previous version about reading only half a mail being a problem doesn't actually matter, since if a client tries to read an expunged mail Dovecot already disconnects the client immediately (since most clients can't handle such situation well anyway). - no more problems with mailbox readers locking out expungers - note about fcntl() locking being able to provide even higher concurrency - works just fine with plain dotlocks, so works fine with NFS And looks like I forgot to explain the "mail header padding" before. I'm not exactly sure if it's useful or not, but it doesn't hurt to have it there if it's wanted. The idea was anyway that if you're writing more than one flag at a time, having a 512 byte padding would make sure that when writing the few bytes the OS will only have to read one sector from disk (512 bytes in all todays OSes I believe?) to get the non-written parts of the sector instead of possibly reading two sectors. So it might help with trading disk reads for some wasted disk space. Generic ------- The point is to have a mailbox format where the mailbox can consist of one or more files. Grouping multiple files in a single file makes it faster to read, but it's slower to expunge mails from the beginning of the file. So this format would allow sysadmin to specify rules on how large the files would be allowed to grow. Index File ---------- Named "index". Index file gives a mapping between UIDs <-> filenames: Header: <uidvalidity> <last-used-uid> Record: <uid-first> <uid-last> <filename> Record: .. eg.: 1127468129 5 1 3 msg.1 4 4 msg.4 All of the UIDs don't have to actually exist in the file if they have been expunged. The record should be removed once all of the UIDs have been removed from it (and the file itself been deleted). The same file may appear multiple times in the index. For example: 1 2 msg.1 3 3 msg.3 4 5 msg.1 This means that UIDs 1, 2, 4 and 5 are in file msg.1, but UID 3 is in file msg.3. The filename doesn't matter as long as it's unique, but probably wouldn't hurt to include its first UID in the filename so humans can find mails more easily. The filename however must not end with ".lock". The file is modified by creating first exclusively owned "index.lock" file, updating it and then rename()ing it over the index file. This lock file shouldn't be held for a long time, so if it exists, and it doesn't get modified at all within 30 seconds, it can be overwritten. Before rename()ing over the index file, you should check with stat() that the index.lock file is still the same as you expect it to be (in case your process was temporarily stopped for over 30 secs). The index file's mtime timestamp must grow after each modification. This makes it easy to check if new mail has been added to the mailbox. Mail File --------- File header: Bytes Format Description 8 hex Header size 16 hex Append offset 4 hex Mail header size 4 hex Mail header padding 4 hex Keyword count in mail headers Mail header: Bytes Format Description 8 hex UID 16 hex Mail size 1 1/0 Answered flag 1 1/0 Flagged flag 1 1/0 Deleted flag 1 1/0 Seen flag 1 1/0 Draft flag 1 1/0 Expunged flag n 1/0 Keywords The file layout then goes: <File header> - possible padding due to Header size <Mail header #1> - possible padding due to Mail header size <Mail data #1> - possible padding due to Mail header padding (ie. next Mail header's offset is divisible with Mail header padding) <Mail header #2> etc.. The UIDs must be ascending within the file (but as said above, some UIDs between them may exist in other files). If mail has been marked with expunged-flag, it should be treated as if it was already expunged. The mail will really be expunged later in some nightly run. Reading the files requires no locking. If while reading you happen to hit unexpected end of file, it means that mails were expunged from the file. After that you'll look at the index file again to see which file the mail went and continue from there on. If the mail isn't found, it means it got expunged. Expunging happens by locking the file and then copying all non-expunged mails after the first expunged one to new file. Then update the index file with the new location for the UIDs, and at last ftruncate() at the position of first expunged mail in the original file. Flag updates require locking the file as well, otherwise we might try to write past the end of file when another process is expunging the mails. Shared locking can be used for flag update locking since each flag update can be atomically changed by writing one byte. Appending mails can be done by either locking existing file and appending to it, or creating a new file. If appending to a new file, create it with .lock suffix and then check that the file without .lock wasn't already just created to prevent race conditions. When appending to existing file, check "Append offset" from file's header. If that offset is at the end of file, just append there. Otherwise read the mail's header from there. If it has a non-zero UID and index file says that the same UID exists in this file, jump over the mail and do the same checks for all the rest of the mails in the file. Once the check doesn't match or you reach EOF, update the append offset in the header to that offset and write your mail there. Initially write the UID in mail's header as zeroes ('0', not NUL). Once the append is completely finished, you'll have to update it with the new UID. You'll do this by locking index file, reading the latest last-used-uid and using the next value for your UID. Once you've written it, rewrite the index file with updated last-used-uid field and your UID added to it. After this, update the append offset in the mail file and unlock it. If fcntl() locking is used, locking only specific ranges can give more concurrency. Flag updates only need to lock the part of the file they're modifying. Expunges need to lock the part which it's removing. Appending needs to lock from <end of file-1> to end of file (ie. l_len=0). Keywords file ------------- Named "index.keywords". This contains mappings between keyword numbers and names. TODO: write how it's updated Recent file ----------- "index.recent.<uid>" file tells what the last non-recent UID was. The file doesn't have any data inside it. When opening the mailbox you should find and rename() the existing index.recent.<uid> file to the new index.recent.<last-uid>. A successful rename() means the mails between <uid>+1 .. <last-uid> are recent for you. A failed rename() means that someone else managed to do it. You should look for the file again and if it was renamed to less than <last-uid>, you should try again. Nightly cleanups ---------------- Because expunged mails may be left lying around for a while, there probably should be some nightly check that cleans them up. Other cleanups that may be necessary after crashes are: - .lock files - expunged data at the end of files (can be checked with same rules as how appending determines the offset where to append) Alternative ways to use ----------------------- Expunging mails isn't very filesystem quota friendly since it requires creating another file to copy the expunged mails to. This could also be done by just moving the data within the file. This however requires that all file reads must also be shared-locked. Also it has the problem of leaving the mailbox corrupted if the copying gets aborted in the middle. For the best performance the mail flags could be stored only in Dovecot's index files. In that case the flag update locking isn't slowing down expunges (and if fcntl() locks can't be used, doesn't slow down appends either). Also there's no need for keywords/recent files. Compatibility ------------- If needed, it would be possible to create new/ and tmp/ directories under the mailbox to allow mail deliveries to be in maildir format. The maildir files would be then either just moved or maybe be appended to existing mail files.

[Dovecot] Mail directory funkiness
by Ted Kaczmarek 27 Sep '05

27 Sep '05

I am using dovecot-0.99.14-4.fc4 on FC4, was testing using mbox and than switched to using Maildir. default_mail_env = maildir:~/Maildir >From evolution when I create a folder the folder is created in ~/mail instead of ~/Maildir I am still rather new to dovecot, but this does not make sense. I made sure to restart dovecot, even added a .procmailrc. cat .procmailrc MAILDIR=/home/tedkaz/Maildir :0 ./ I am going to grab the latest version and test with that, but if if anyone has insight into how I got here it would be appreciated :-) Likely a pilot error.

[Dovecot] Misbehavior with Dovecot and Mulberry
by Jon Roma 27 Sep '05

27 Sep '05

I'm having a bit of misbehavior wherein Dovecot seems to refuse to cooperate with my Mulberry MUA. By and large, everything works great. I can move mail back and forth happily. I can compose a note and copy the outgoing mail to my Dovecot "Sent" folder using my default Mulberry settings. But if I reply or forward a mail, I get a Mulberry error popup saying that it "couldn't decode the response from the server" and that the operation was unsuccessful. This was somewhat mystifying (especially since this does work for a newly composed message as opposed to a reply/forward), so I turned on Mulberry logging. This is what I see (with unrelated operations clipped from the log). First, the first case where I create a new message, send it, and save a copy in my Sent folder: --> #6.3408 Mon Sep 5 23:24:27 2005 A00085 APPEND Sent (\Seen) {418+} * 5544 EXISTS * 1 RECENT A00085 OK Append completed. All's well there. Mulberry does a FETCH to grab the new message (reply) from my Sent folder and then does a SORT so that it can order it properly in the display. This too succeeds but is probably irrelevant to us. After a couple NOOP commands come and go in the background, I try to reply to a message in one of my mailboxes. In this case it happens to be the one in my Sent folder. So Mulberry issues a FETCH (you can see the original mail there in the FETCH response from Dovecot). It then does a STORE of the original mail, apparently to update the \Answered flag. It then tries to APPEND the reply to the Sent folder, but this time, the server comes back with a NO. See below --> #6.3408 Mon Sep 5 23:24:43 2005 A00089 FETCH 5544 (BODY[1]) * 5544 FETCH (BODY[1] {63} ) A00089 OK Fetch completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00090 FETCH 5544 (RFC822.HEADER) * 5544 FETCH (RFC822.HEADER {355} Date: Mon, 05 Sep 2005 23:24:27 -0500 From: Jon Roma <roma(a)uiuc.edu> To: Jon R Roma <roma(a)uiuc.edu> Subject: Test 1 Message-ID: <DDDD999F0F4E38F8C1510CC8(a)jrr2.isdn.uiuc.edu> X-Mailer: Mulberry/3.1.6 (Win32) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline ) A00090 OK Fetch completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00091 STORE 5544 +FLAGS (\Answered) * 5544 FETCH (FLAGS (\Answered \Seen \Recent)) A00091 OK Store completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00092 APPEND Sent (\Seen) {610+} A00092 NO I am having similar problem saving a draft to my Drafts folder and suspect the same thing is behind both of these. I didn't create a Mulberry trace log for this but can do so if need be. I am running 1.0-test80 with Timo's patch to fix the "time off by 200 minutes" error with mbox. All my folders are maildir at this point -- I've converted them out of my UW mbx format store. My client is Mulberry 3.1.6 for Windows and the OS is AIX 5.1. This weird behavior is a mystery to me!

[Dovecot] 1.0alpha3 packages for debian
by Jaldhar H. Vyas 26 Sep '05

26 Sep '05

Sorry this took even longer than I thought but they should be arriving in unstable this afternoon. I also have a backport for stable available at http://www.braincells.com/backports This directory is not aptable so manually install the packages for now. (Hopefully backports.org will have their sarge repository open soon. When that happens they will move there.) The configuration file format has changed so you will want to carefully check /etc/dovecot/dovecot.conf when upgrading. I forgot to put a note about that in NEWS.debian sorry. I think I might have forgotten a couple of config file tweaks people have suggested and in general, if you sent me mail in the past month or so and I didn't respond or the problem still isn't fixed, please give me a nudge. This is why you really ought to use the Debian bug tracking system rather than mailing the maintainer. Anyway, enjoy. -- Jaldhar H.

[Dovecot] virtual domain
by Barry Kwok 26 Sep '05

26 Sep '05

we are currently using vm-pop3d to implement virtual domains. But due to some locking problem in vm-pop3d, we want to test the possibility to change to dovecot. Currently, in vm-pop3d, the passwd file is located in /etc/virtual/domain1.com/passwd /etc/virtual/domain2.com/passwd and the passwd format is: user: md5 encrpted password and the email is store in /var/spool/virtual/domain1.com/user /var/spool/virtual/domain2.com/user and we login as user(a)domain1.com, user(a)domain2.com . We want to maintain this format as login id and the password format. What should be changed in dovecot.conf? Thanks.

[Dovecot] Dovecot LDAP authentication not working
by Kondwani Masiye 24 Sep '05

24 Sep '05

Hie all, I am new to both Dovecot and this list. I am trying to set up a Dovecot and Sendmail mail server with OpenLDAP user database for authentication. The sendmail setup is working fine, but authentication for Dovemail is not working. When I try to authenticate using POP3, I get an "authentication failed" error, and the logs show the following: Sep 19 16:53:21 tempo slapd[6316]: conn=74 op=2 SRCH base="dc=domain,dc=net" scope=2 deref=0 filter="(&(objectClass=posixAccount)(uid=kondie))" Sep 19 16:53:21 tempo slapd[6316]: conn=74 op=2 SRCH attr=uid userPassword Sep 19 16:53:21 tempo slapd[6316]: <= bdb_equality_candidates: (uid) index_param failed (18) Sep 19 16:53:21 tempo slapd[6316]: conn=74 op=2 SEARCH RESULT tag=101 err=0 nentries=1 text= Sep 19 16:53:21 tempo dovecot: auth(default): ldap(kondie,127.0.0.1): password mismatch Sep 19 16:53:25 tempo dovecot: pop3-login: Aborted login [127.0.0.1] Sep 19 16:53:25 tempo slapd[6313]: conn=72 fd=14 closed I know the password is correct because I am using the same LDAP database from a different server using UW Imap and it works. My dovecot-ldap.conf file below: hosts = localhost dn = cn=dovecot,dc=domain,dc=net ldap_version = 3 base = dc=domain,dc=net deref = never scope = subtree user_attrs = uid,homeDirectory user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid,userPassword pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = CRYPT And the relevant parts (I think) from dovecot.conf file: I have googled all over and also the archives of this list for the last few months but I have not been able to work out what the problem is. As a matter of fact, I have tried to set it up the way it is described here: http://wiki.dovecot.org/moin.cgi/DovecotOpenLdap - but no luck. Could someone please assist in resolving this problem.

[Dovecot] Fatal: EOF reading environment from master
by Marcathian Alexander 24 Sep '05

24 Sep '05

I have been running dovecot as an imap server since 22nd July 2005. The server was started from xinetd using /usr/local/libexec/dovecot/imap-auth The sever run successfully until the machine was shut down in a power outage on 12 Aug 2005. Dovecot has failed to start since the reboot. When starting it with the imap-auth it gives the following error: fatal: EOF reading environment from master I have uninstalled dovecot, downloaded, compiled, and installed the stable of 14Aug 2005 and got the same error. I then installed the 0.99.14 version ang got the same error. Can i have assistance in solving and/or diagnosing the problem? -- Marcathian Alexander SDE Assistant Sustainable Development and Environment Section Ministry of Physical Development, Environment & Housing Open Source Software Evaluation Project - WebMail/Groupware/Collaboaration [Open WebMail Project (http://openwebmail.org)

[Dovecot] auth protocol, buffers
by Thomas Hummel 24 Sep '05

24 Sep '05

Hello Timo, I'm curious about 2 points (I'm using alpha2 but these are general questions) : Background : . I connect to dovecot-1.0.alpha2 through thunderbird . I use ldap pass/userdb and PLAIN mech . I've only got one auth block in dovecot.conf (all pass/userdb/mech except ldap/PLAIN are commented) 1) I notice that, for one thunderbird connection trial, imap-login issues 2 AUTH messages. Why ? What info does the "resp=" hold the second time ? It goes like this : Info: Dovecot v1.0.alpha2 starting up Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx Info: auth(default): client out: CONT 1 Info: auth(default): client in: CONT 1 AGRvdmV0ZXN0AGZvbw== Info: auth(default): ldap(dovetest,xxx.xxx.xxx.xxx): base=ou=personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(uid=dovetest)) fields=uid,userPassword Info: auth(default): ldap(dovetest,xxx.xxx.xxx.xxx): userPassword(password)={CRYPT}sa8ufSVwLUHVU uid(user)=dovetest Info: auth(default): client out: FAIL 1 user=dovetest Info: auth(default): client in: AUTH 2 PLAIN service=IMAP lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx resp=AGRvdmV0ZXN0AGZvbw== Info: auth(default): ldap(dovetest,157.99.64.42): base=ou=personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(uid=dovetest)) fields=uid,userPassword Info: auth(default): ldap(dovetest,157.99.64.42): userPassword(password)={CRYPT}sa8ufSVwLUHVU uid(user)=dovetest dovecot: Sep 20 17:58:27 Info: auth(default): client out: FAIL 2 user=dovetest 2) Which buffer/string handling function (among those in your lib) should I use to safely allocate a string and/or copy a string into another ?

[Dovecot] 1.0 alpha3 released
by Timo Sirainen 24 Sep '05

24 Sep '05

I'm a bit too busy nowadays because of school so I haven't had time to look at everyone's bug reports and some other mails. They're still marked as unread in my mailbox, so hopefully I'll get to them soon. And I don't mind you resend them if I don't answer in a few weeks :) Changes: - Fixed maildir syncing errors about wrong UIDs - Maildir was re-read all the time, even if we knew nothing had changed there - SSL/TLS connections used to have extra ~0.2s latencies because kernel was waiting for more data before sending it (at least with Linux). Fixed it by corking/uncorking before/after sending. I don't think the socket latencies are this bad normally though, I should probably look more into it if we're setting some socket flags badly (or does it happen specifically because we were using corking for the socket before SSL and kernel increased the timeouts because it thinks we're going to be using corking?). - Marking index file corrupted caused its recreation to still use old transaction log file, which usually caused the index to get corrupted again - Added --build-options parameter to dovecot binary (by Andrey Panin) - Parse obs-phrase correctly in mail address parser (by Chris Wakelin)

[Dovecot] dovecot with ssl only works on foreground mode
by blaq b0x 24 Sep '05

24 Sep '05

Hi, I've set up dovecot to use imaps/pops with certificates that I signed with my own CA. When I try to start it using service dovecot start it fails. I've tried disabling imaps in the config file and it starts fine so it seems it's the certificate part of the config. If,however, I start it with '/usr/sbin/dovecot -F' or even '/usr/sbin/dovecot' it starts! I've looked over the dovecot startup script but, can't seem to see anything that would hinder startup. I didn't have this problem with self-signed certs??? Can anyone shed some light on this? Thanks, __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[Dovecot] Maildir and folders not under INBOX
by Oliver Schulze L. 23 Sep '05

23 Sep '05

Hi, I'm planning to migrate from dovecot/mbox to dovecot/maildir both using imap. I have read that when using the Maildir storage format, all folders are stored under the INBOX. Is this true in dovecot too? I want to have a configuration like the current: - new mail is delivered in /var/mail/USER - user folders are in /home/USER/mail I want to ask if this is posible in dovecot? Maybe using a config like this: default_mail_env = maildir:/home/%u/Maildir:INBOX=/var/mail/%u/Maildir Thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] Moving messages takes a longgggggg..... time. (Timeouts?) dovecot.conf help?
by Rob Frohne 23 Sep '05

23 Sep '05

Hi, I'm trying to get dovecot set up better. I am using 1.0alpha3. It takes a long long time to move messages for some reason. It seems it may be a timeout thing, because neither the client or server is using any cpu time or disk i/o or network to speak of. (To move maybe 400 messages, it seems to take maybe half an hour, maybe longer.) With alpha 2 I was getting messages from Thunderbird saying that the server was unable to move messages, would I like to continue. I haven't seen any of these lately, but when I updated to alpha3 I also made some dovecot.conf changes. I'm running this on OS X with a 450 MHz cube with 1.2 Gig of ram and a 7200 RPM hard drive. I have a lot of rules that move messages to various mailboxes and I get a lot of mail, so this is important to me. I have a very large Maildir set of mailboxes (about 40 of them with up to 70,000 messages in each mailbox). I have finally got it so that it will load the mailbox headers pretty quickly in Thunderbird. It takes about 15 to 30 seconds to load a message, but that is acceptable to me. Here is my dovecot.conf. Can anyone give me some tips? ## Dovecot 1.0 configuration file # '#' character and everything after it is treated as comments. Extra spaces # and tabs are ignored.

There's four available: # dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe # solution.

[Dovecot] signing dovecot certs with own Cert. Auth.
by blaq b0x 23 Sep '05

23 Sep '05

Hi, I'm trying to get apache, sendmail , and dovecot to use SSL certs signed by my own CA. I've got the apache certs working fine. However, dovecot ( I haven't even tried sendmail yet) doesn't seem to accept any of the certificates that I create for it. There is a script that comes with dovecot that creates self-signed certificates for you but, I need certificates signed by my own CA. I found this tutorial http://homepage.mac.com/pauljlucas/personal/macmini/certs.html it shows you how to create a csr for dovecot that you can send to a CA. I signed it using CA.pl -sign. however, the certificate isn't accepted by dovecot. Unfortunately, dovecot doesn't log anything to maillog at failed startup. Just looking at the certificate contents I noticed that the self-signed certificates don't have all kinds of publisher information at the beginning of them like the apache certs. So I think what I'm missing is the difference between all the different cert types. I know that there are pem and cert ssl cert types, at least different extensions. Can anyone tell my what the difference is? are the certs suitable for apache and others for mail applications? is there a converter? Could it be the way that I'm signing the certificates? Any help would be appreciated. Thanks, Reply With Quote __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

[Dovecot] Lost transaction log file in alpha2
by James Berry 23 Sep '05

23 Sep '05

I had run alpha1 pretty uneventfully for several weeks. I upgraded to alpha2 a couple of days ago and have since suffered two incidents of "Lost transaction log", resulting in the client being unable to access the mailbox until I "rm dovecot.index.log*" Sep 14 10:48:35 caddy dovecot: imap(jberry): Lost transaction log file /Users/jberry/Maildir/dovecot.index.log seq 1 I should point out that this is a server with a single imap user (myself) and that I know only one imap client was trying to access the server at that point in time (though the client sw Mail.app may have had multiple connections to the server). Any suggestions/ideas/thoughts on whether something might have changed in alpha2 to start causing this? James.

[Dovecot] auth-master socket access

Hey, I'm doing a setup of dovecot (cvs) + postfix + dovecot lda (cvs). Is there any solution to the /var/run/dovecot/auth-master access restrictions, prohibiting the user running dovecot-deliver from communicating with the master (aside from the dirty and unsafe hack to reset the permissions of the /var/run/dovecot dir after starting dovecot)? Thanks, Lieven

[Dovecot] Can't donwload mails with some attacchments

Hi. Does anyone find the same problem with attachments bigger than few Ks? The client (thunderbird) waits for the file to be downloaded. It can be waiting for several minuts and tryies before having it from dovecot. Can it be something against the lock of the file, the processes or something else? Any workaround or bugfix in the stable/alpha rel? thanks. L.

[Dovecot] Basic namespaces question
by David King 23 Sep '05

23 Sep '05

I can't find a generalised "What the heck are namespaces all about?" anywhere, can anyone point me to a decent one? More directly, my question is this: if I set up two non-hidden private namespaces (one for mbox and one for maildir), will a well-written IMAP client automagically list folders from both as if they were part of (or below) the same hierarchy, or do I have to set up two accounts, one with a prefix of (say) #mbox and one of #maildir? One step further, I'd like to eventually get mail from /var/mail/%u in mbox format, and in "maildir:%h/.maildir" or "mbox:%h/.mail", whichever exists (I'm migrating from imap-uw, and would like the benefits of maildir without forcing users to change their mailstores in case they use pop3 or tools like mail(1)). I'm willing to do some coding for it, but I imagine that it would be non-trivial if namespaces aren't automatically integrated

Doesn't go away by restarting dovecot, but does go away when I delete all index and cache and whatnot (and restart dovecot). Appears in 10 minutes again... Could be sylpheed-claws-whatever-alpha imap problem, but whatever the client does dovecot shouldn't be fall apart I believe. Peter

[Dovecot] Another address-spec problem
by Chris Wakelin 23 Sep '05

23 Sep '05

I've had complaints from users about "MISSING_DOMAIN" in header fields and I've tracked it down to having "." in an unquoted display name. By my reading of RFC2822 (especially section 4.1) A N Other <a.n.other(a)somewhere.org> "A. N. Other" <a.n.other(a)somewhere.org> are legal, but A. N. Other <a.n.other(a)somewhere.org> is "obsolete", but should be supported by the server (no clients should do it). I think the relevant syntax is phrase = 1*word / obs-phrase word = atom / quoted-string obs-phrase = word *(word / "." / CFWS) and rfc822_parse_phrase() should be modified to cope with "obs-phrase". I'll have a go, but if Timo or anybody knows how to do it properly, that would be better!

I have tried to do 'echo -n mypassword | openssl md5 -hex' and insert that into them but it seems to not work. Probably something I am doing wrong.

[Dovecot] problem with postgreSQL connect=
by octane indice 22 Sep '05

22 Sep '05

Hello I'm using dovecot with virtual accounts stored in a postgreSQL db. I use in the dovecot.conf: auth_userdb = pgsql /usr/local/etc/dovecot-pgsql-user.conf (and same for pass). In the file dovecot-pgsql-user.conf, I use: connect = host=127.0.0.1 dbname=vmail user=lecteur password=lire user_query = SELECT '/var/spool/vhosts/'||nom_domaine||'/'||nom_boite AS mail,5000 AS uid, 5000 AS gid FROM boites WHERE email = '%u' It doesn't work. If I write: connect = dbname=vmail user=lecteur user_query = SELECT '/var/spool/vhosts/'||nom_domaine||'/'||nom_boite AS mail,5000 AS uid, 5000 AS gid FROM boites WHERE email = '%u' It works. Of course the query with psql works: psql -U lecteur -h 127.0.0.1 vmail -c "SELECT '/var/spool/vhosts/'||nom_domaine||'/'||nom_boite AS mail,5000 AS uid, 5000 AS gid FROM boites WHERE email = '%u' " with the password 'lire' My question: do I make something wrong? I want to use the network, because in future, dovecot will not be on the same host than postgreSQL. Thanks --------------------------------------------- Etes vous un consom'Acteur ?

[Dovecot] Weird series of errors with dovecot-stable
by Ben Beuchler 21 Sep '05

21 Sep '05

I'm using the dovecot-stable from 7/30, authenticating against an OpenLDAP server. From time to time, dovecot stops responding to new queries. It seems to be a self-correcting problem, lasting about 20 minutes. Here's how it starts: Aug 18 19:38:23 cliff dovecot: imap-login: Disconnected: Inactivity [150.253.42.12] Aug 18 19:38:36 cliff dovecot: pop3-login: Disconnected: Inactivity [68.46.174.217] Aug 18 19:39:35 cliff dovecot: imap-login: Disconnected: Inactivity [150.253.42.12] Normally I see almost no "Disconnected: Inactivity" messages, but when this problem shows up I get an almost non-stop barrage of them. In fact, over the 20 minutes or so, there's about 150 of those entries, so I filtered them out of the log snippets. I also filtered out any "normal" activity during the time period.

[Dovecot] ALL TCP/IP connection REST when one mail contains format error
by Yi Xuan 20 Sep '05

20 Sep '05

Hi, I have setup a dovecot pop3 server on IP_A and using mbox format I have 6 users behind a NATed network, the public IP is IP_B. And one mail of one user seems contain format error. He always cannot receive the 5th mail from anywhere. Then when he receive mail in the intranet, all the TCP/IP connection REST between IP_A and IP_B. http/ssh/pop/smtp etc. all NG. After I delete the 5th mail from webmail, then the services work well. 1.It seems unreasonable, Can dovecot improve it and let it donot influence other users and other service? 2.What may cause mbox format error? and how can we avoid it? Best regards,

[Dovecot] Two strange behaviours with dovecot+postfix+squirrelmail
by Francisco Neira 20 Sep '05

20 Sep '05

Hi all, About a week ago I was forced to migrate my main (production) email server from RH9 to Centos4.1. The installation has dovecot-0.99.11 + postfix-2.1.5 and >600 mbox accessed email accounts. Number 1. Some users accessing thru squirremail (installed in my webserver) can read their INBOX at /var/spool/mail directory but when trying to delete a message they receive the following error message from squirrelmail: ERROR: Could not complete request. Consulta: COPY 1279 "mail/Trash" Reason Given: Internal error occured. Error report written to server log. [2005-09-16 15:08:04] and the error logged is the following: Sep 16 15:09:27 mail imap(username): mkdir_parents(/home/username//mail/.imap/Trash) failed: Permission denied I never stated that .imap/Trash when configuring dovecot and the strangest thing is that my account, as most of others, can delete messages moving from /var/spool/mail/my_name to /home/my_name/mail/Trash Number 2. Randomly, some users connecting from Mozilla Thunderbird via IMAP get an error message telling that there has been an error connecting to INBOX. Watching the maillog I found the following: Sep 16 13:07:43 mail imap(otheruser): File isn't in mbox format: /var/spool/mail/otheruser I accessed the user's inbox file with vi and found that there was a "--604" at the beginning of the file. In other case I found that the file was beginning with a truncated email message. Trying to "walk on the safer side", I changed the mbox_lock setting from "fcntl" to "dotlock" in the /etc/dovecot.conf file. Any suggestions and comments about his will be highly appreciated. Forgive me about my English, it is not my native lanaguage. Regards, -- Francisco Neira B. Administrador de Red Defensoria del Pueblo Lima, Peru, -05:00 UTC

[Dovecot] NO: Unsupported authentication mechanism
by Steve [Dovecot] 19 Sep '05

19 Sep '05

I'm happily using dovecot as my IMAP server and accessing mails using Thunderbird... but I want to use the Net::IMAP facilities in the Ruby standard library to write some scripts to automate various spam-related tasks & housekeeping. My Ruby script: require "net/imap" imap = Net::IMAP.new('localhost') imap.authenticate('LOGIN','myuser','mypassword') # More stuff using imap... From the documentation LOGIN uses plaintext authentication - which I understand is always acceptable for Dovecot when connecting from localhost. On the 3rd line I get a "NO response" exception raised (indicating that the IMAP server replied "NO") and the error message "Net::IMAP::NoResponseError: Unsupported authentication mechanism" If I change 'LOGIN' to 'CRAM-MD5' (the other value supported by Net::IMAP) then I get a similar (but not identical) error: "Net::IMAP::NoResponseError: Authentication failed: Unsupported authentication mechanism" If I use anything other than either 'LOGIN' or 'CRAM-MD5' I get an error from the Net::IMAP library saying "Unknown auth type" - which is reasonable. N.B. I've tried both where 'myuser' and 'mypassword' are valid - and not... this doesn't affect the error messages. There doesn't seem to be anything of interest in /var/log/messages... Can anyone tell me what is going wrong, and how to resolve this?

[Dovecot] FreeBSD port
by David King 19 Sep '05

19 Sep '05

FreeBSD users: I notice that the version of Dovecot in the FreeBSD ports system is back at .99. Are there any objections to my submitting an update to the FreeBSD ports for version 1.0a? Is it better to wait for 1.0 to be progressed a little or is it considered to be ready? 1.0a compiles and seems to run fine (on 5.3), so are there any obvious patches that would be needed for the FreeBSD build? -- Don't forget that 19 September is National Talk-Like-A-Pirate Day! http://www.talklikeapirate.com/piratehome.html

[Dovecot] Very minor feature request
by Steffen Kaiser 19 Sep '05

19 Sep '05

Hello, I'd suggest a way to get to know the "capabilities" of a compiled Dovecot. The background is that I've run the sequence ./configure --with-ldap && make && make install twice, all three commands tell me that all is fine (ldap is listed in the modules), but still dovecot told me that ldap is no Usedb module. A "make clean" before solved the problem -- well, something one should anyway. Besides, the "dovecot --capabilities" should also list all the defaults. Bye, -- Steffen Kaiser

Hi, my name is Andrés Rusconi, from Tucumán, Argentina. Sorry my English, please. I am a very happy new user of Dovecot: I gained speed and simplicity with him. But I noticed that in clients who use Outlook, the deleted messages do not copy to the trash folder. This is not critical, but did not happen with Courier, and the users askme about this behavior. If some of you has somehow solved this small question, I will thank for their commentary. Saludos Andrés

The thing is, it keeps happening and I can't figure out why. Email clients that send mail to these accounts are the latest Outlook Express. As I said, I have 150+ users on the same system and they are fine. I'm not sure if protocol makes a difference, but we are using POP3 only. Any ideas what I can do to fix/prevent/correct this either programatically or with a patch of some sort? Is this actively being worked on? I'm running FC4 with dovecot-0.99.14-4.fc4.

[Dovecot] Dual INBOX Locations

G'day list, Just a quick question - I need to configure Dovecot to do the following: * check default_mail_env for the users' inbox in MBOX format * If the above fails, serve the user an inbox from a secondary location, in MAILDIR format. I have read up on Namespaces, however I can't seem to get this to work - login just fails when Dovecot cannot find the inbox in default_mail_env Any advice, anyone? :) Thanks, Calum -- Calum Power Systems Administrator Server101 Pty.

[Dovecot] problems with Auth and Alpha 1a
by Søren Peter Skou 18 Sep '05

18 Sep '05

Hi all I'm not quite sure how to explain this problem, so I'll just go from the top ;-). System is setup on a FreeBSD with IMAP and POP3, both can use PAM and SQL (MySQL) as login methods, though only POP3 is accessible from "the world" - IMAP is restricted via firewall to only localhost. Simple eh? The problem is that dovecot apparently drops the SQL part from time to time. Though this can be fixed by HUPing the dovecotdaemon I'd rather that I didn't have to. I've narrowed the problem to something like this: Over time, Dovecot/POP3/SQL combination dies - I've yet to examine if the problem is on IMAP as well as this is only recently reported. I have never experienced this myself since I'm using Dovecot/IMAP/PAM and this seems to be rock solid. The configuration looks like this: OS: FreeBSD n/a 6.0-BETA3 FreeBSD 6.0-BETA3 #0: MySQL: 5.0.9-beta-log Dovecot: alpha 1 (I'll test Alpha 2 to see if the problem persists) Compilation options for dovecot: ./configure \ --enable-ipv6=no \ --with-ldap=no \ --with-vpopmail=no \ --with-mysql \ --with-ssl=no dovecot.conf: base_dir = /var/run/dovecot/ protocols = imap pop3 ssl_disable = yes disable_plaintext_auth = no login_user = dovecot login_process_per_connection = no login_greeting = Ready max_mail_processes = 1024 first_valid_uid = 1 first_valid_gid = 1 protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } passdb sql { args = /usr/local/etc/dovecot/mysql.conf } userdb sql { args = /usr/local/etc/dovecot/mysql.conf } user = root } -- END -- sql.conf: driver = mysql connect = host=localhost port=3306 dbname=N/A user=N/A password=N/A client_flags=0 default_pass_scheme = CRYPT password_query = SELECT password FROM mail WHERE username = '%n' and domain= '%d' user_query = SELECT concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as home,concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as mail, 1 as uid, 6 as gid FROM mail WHERE username = '%n' and domain = '%d' -- END -- I'm sort of at a loss here since everything "seems to be working" (tm) for one part, but not another Hope someone has an idea ;-) Søren P.

[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes
by rick tait 18 Sep '05

18 Sep '05

Hi everyone: I am seeing a whole LOT of these messages in my dovecot logfile: imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 0 imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 1 and also these: imap(mbwnews): Sep 12 17:10:16 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) imap(mbwnews): Sep 12 17:10:18 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) And not just referring to my inbox, other users as well. I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] Timeout while waiting for lock....
by Rob Frohne 16 Sep '05

16 Sep '05

Hi, I'm very new to administering mail, and this is surely a newbie question. I have my own IMAP mail server because I use my email as a way of filing important things, and I subscribe to a number of lists that I like to archive. I have about 40 mailboxes with up to 80,000 messages in some, and one with 40,000 messages is almost a Gigabyte in size. The total size is around 4 Gigabytes. Things were working quite well until I upgraded to OS X 10.4 and its new Mail.app mail client and then everything was too slow. I was using the UW IMAP server (2002d if I recall right) and Mail.app 1.3.9. I tried upgrading the server to the latest, but it didn't improve things noticeably. I swapped to dovecot 1.0alpha1, and used the mbox format, but that wasn't any better. I read that Maildir format was better, so I converted my mail to that format and tried that. It didn't seem much better. I tried to compile Cyrus on OS X and ran into all kinds of difficulty. I finally tried Cyrus on a Linux box, and turned off all my rules that move messages around. In comparing this to dovecot on my OS X box, Cyrus loads the messages significantly faster. I think there are some problems with my dovecot setup though. My mail.log is filled with this type of thing. Sep 15 16:43:51 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=PLAIN, rip=172.17.128.191, lip=10.7.3.11 Sep 15 16:44:43 cubex-wwc-edu dovecot: imap(frohro): Timeout while waiting for lock for transaction log file /Users/frohro/Maildir/dovecot.index.log Sep 15 16:44:57 cubex-wwc-edu dovecot: imap-login: Login: user=<frohro>, method=PLAIN, rip=172.17.128.191, lip=10.7.3.11 Sep 15 16:45:51 cubex-wwc-edu dovecot: imap(frohro): Timeout while waiting for lock for transaction log file /Users/frohro/Maildir/dovecot.index.log I've tried mutt, evolution, kmail, and am now using Thunderbird, and am working on getting Mail.app to import an archive of my 4 Gigs of mail, thinking if nothing else works, I can have a copy of that on the clients I use, though I like having it on the server better. Can anyone suggest something to fix my problems, besides deleting all my email? Thanks, Rob

I have both 1.0 alpha1 and alpha2 installed on my test mail server. SSL/TLS does not work on alpha2. I'm using the same config file for both. No errrors in dovecot.log either. Is there a way to increase debugging info without recompiling?

[Dovecot] Dovecot-LDA problems (CVS version) Signal 11 and empty 'mail' dir
by Steffen Kaiser 14 Sep '05

14 Sep '05

Hello, I'm trying dovecot-lda (deliver.c has CVS version 1.18). When I try to deliver a mail, an empty directory is created name $HOME/mail. This is neither the configured (via LDAP) nor the default "mail" setting in the /usr/local/etc/dovecot-deliver.conf. When the $HOME directory does not exist, but the user itself: Sep 1 11:47:12 localhost deliver: mbox: Can't create root IMAP folder /home/skaise2a/mail: Permission denied Sep 1 11:47:13 localhost sm-mta[4684]: j819lCgd004682: SYSERR(root): mailer local died with signal 11 Default mail: mail = maildir:%h/.mailboxes:INDEX=/usr/local/var/spool/dovecot/indexes/%Lu Configured via LDAP for user skaise2a: maildir:/mailcache/skaise2a:INDEX=/var/cache/dovecot/indexes/skaise2a:CONTROL=/var/cache/dovecot/control/skaise2a I have only found the error message in dovecot's src/lib-storage/index/mbox/mbox-storage.c function create_root_dir(). The Dovecot logs indicate that dovecot-lda is requesting the information from it and the message is - once the empty directory could be created - delivered into the configured IMAP root.

Locking _does_ work for postfix and dovecot (discussed with Wietse, partly by mail). Any idea? As an alternative, is there a way of handling the problem better?

[Dovecot] An alternate "dovecot-auth" daemon using cyrus-sasl
by buc 12 Sep '05

12 Sep '05

We use dovecot in a heterogeneous environment (Windows/Linux desktops and Linux servers). For unified authentication we use a sheaf "Samba/Openldap" (i.e., Samba NT domain with openldap backend and pam/nss_ldap for Linux). Windows users are authenticated well everywhere, but there is one old issue. As "SPA" (NTLM) against NT domain is not supported by dovecot, it is necessary to use default "plain" method. In addition to security problems, it does also a problem of password unification. Each time a user changes the password, he should do it one more time for the mail program. I know that dovecot supports NTLM, however against local database only (not for NT domain controller). In early versions support of cyrus-sasl (which supports NTLM now) had been incorporated, however it like not work and now is removed. Fortunately, there is a possibility to substitute dovecot-auth executable. Therefore I have tried to make an alternate variant of dovecot-auth, which supports all that we need. For us, it seems to be more useful to create an auth daemon using cyrus-sasl, rather than to add domain support to existing ntlm code. First of all, it is easier for implementation. Besides it enables use of all mechanisms supported by cyrus-sasl (present and future), including GSSAPI. Anyway, it will be the useful additive to dovecot. I have made appropriate patches for both dovecot-1.0-stable and dovecot-1.0.alpha1. The idea is to copy "src/auth" to "src/auth-cyrus", strip all unneeded from newly created directory and add cyrus-sasl support. The resulting code probably looks not so elegantly as if it has been written separately, however this way allows to not make a lot of things from the scratch. The patch against 1.0.alpha1 is here: http://dmitry.butskoy.name/dovecot/dovecot-1.0.alpha1-cyrus.tar.gz . To be more readable, it is not a flat patch (due to a lot of whole files add/remove). It is a tarball with 3 files: a list of files to initial copy from auth/ to auth-cyrus/, a patch for resulting tree, and a script which automates this steps (:-)). (The script should be run in the root of the main source, i.e. a dir with src/ and doc/ subdirs). I already have successfully tested this patch with PLAIN method. However before testing of other methods, it would be desirable that somebody have looked at it. Whether someone could check up my patch (just fluently having read), at least for obvious bugs and typos?

[Dovecot] Dovecot feature request: move /var/mail/uid to INBOX
by Steffen Kaiser 12 Sep '05

12 Sep '05

Hello, UW-Imap has a (questional, but for me useful) feature to slurp all mails pending in /var/mail/uid into the user's INBOX whenever the user successfully logs on and the INBOX is not configured as /var/mail/uid. The usefulness for me is that users have a relatively small quota, so the noisy "over quota" messages pop up for everyone now and then, regardless how frequent one reads the mail. When I now set a large quota for the "pending INBOX", where the user (aka dovecot) can only delete mails from, I circumvent those messages, prevent that users use the (large) INBOX as yet another place to pile up data (the user does not know about the pending INBOX at all) and let the users have "full" control over their folders. The disadvantage is that it works for "real" users only. Another disadvantage is that one would expect "LDA"-features in the server portion of Dovecot, e.g. Sieve :-), or the server would need to spawn the Dovecot-LDA somehow. (Next thing is that, currently, the mails are delivered into the home directory of the users, what leads to several annoyances when someone is away for some time and finds his home directory locked, because the mass of mails locked the directory. Mostover, those IMAP servers I ran so far didn't allowed the user to delete a mail via IMAP often, because some temp or arbitary file couldn't created in the IMAP root. Because the user is already logged on onto Dovecot, there should be less problems deleting mails when the quota exceeds while slurping them in. At least I had extremly good experiences with this mechanism, when I used UW-Imap and the INBOX was located as mbx in the user's homedirectory.) Bye, -- Steffen Kaiser

[Dovecot] reading subfolders with mail.app

Hi all, I have been having a hard time using Fedora Core 4 with dovecot +sendmail. Namely, I cannot read my home dir's procmail filtering dir (where I have some subfolders) in ~/mail. I cannot create mailboxes either. I'm wondering if this is a client issue, and whether I need to switch to Maildir, which I'd like to do, but don't know how to with sendmail (with postfix, it's a piece of cake). Any advice on what my problem is? I'm all ears! regards, Patrick

[Dovecot] 1.0alpha2 released
by Timo Sirainen 12 Sep '05

12 Sep '05

Changes: - Some cache file corruption fixes (shouldn't be any left?) - Some index file fixes with mmap_disable=yes - Some mbox syncing fixes - Timezones in mbox From-lines were handled wrong - Added pop3_reuse_xuidl setting. Patch by Chris Wakelin - "stack frame changed" crashfix for FETCH BODYSTRUCTURE - Added %R (reverse string) and %H (hash string) variable modifiers. These can be useful if you want to automatically split users to multiple partitions (eg. %3RHu gives values 0..2 based on the given username). See doc/variables.txt for more information. The POP3 bug mentioned in ChangeLog doesn't actually exist, so don't be alarmed by it :)

[Dovecot] Do index files need removing when upgrading 1.0-stable to 1.0-alpha1 or later?
by Chris Wakelin 11 Sep '05

Hi Timo, Just a quick question: do index files still need removing when upgrading from 1.0-stable (as in the testXX series) or will Dovecot regenerate them automatically? I'm expecting to go with 1.0-stable on Tuesday for my 20,000 users (as that's what I've been testing), but if we see lots of index issues, I may want to upgrade to alpha1 (or later) fairly soon afterwards and it would be annoying to have do delete thousands of indexes!

[Dovecot] subscriptions or .subscriptions?
by Andy Cravens 11 Sep '05

11 Sep '05

I may have found a problem with the documentation concerning the subscriptions file. On the Dovecot web site there is a document that outlines the conversion from UW IMAP to Dovecot. The document says Dovecot's folder list is stored in ".subscriptions" However, I have found that Dovecot's folder list is really "subscriptions" without the preceding dot. Did Dovecot version 1.0.alpha1 remove the dot from the subscriptions filename? .subscriptions does not seem to work at all. http://wiki.dovecot.org/moin.cgi/Migration#head-5dde807bf059dea93fc2303e202…

[Dovecot] buglet in dovecot.conf, 1.0alpha1

Timo, The dovecot.conf file comments talk about login_process_per_user but this variable does not appear in the file. Do you mean login_process_per_connection instead? Jeff Earickson Colby College

[Dovecot] Problem in dovecot 0.99 - login username case sensitive create fake maildirs
by Max CtRiX 11 Sep '05

11 Sep '05

Hello, I have noticed a weird behaviour in dovecot 0.99 which, I hope, is not replicated in 1.0-alpha. First I have to say that it works very well. So if I login with user foo(a)bar.com, the maildir is created. But when I log in with User FOO(a)BAR.COM, or FOO(a)BAR.com, then two other maildirs are created. Authentication is ok (I'm using mysql backend) but no mails are obviously found. Maybe a solutions would be adding some config item to turn lowercase the maildir path or authentication tokens (received from client) at login time. Or maybe I am missing something. Is there a solution for this problem out there ? Thanks, Massimo

[Dovecot] POP3 problem about multi users from one IP address concurrent
by Yi Xuan 11 Sep '05

11 Sep '05

Hi,all I have a POP3 problem about multi users from one IP address concurrent. [Issue description] The network architecture is as following. I have setup a mail server(sendmail/dovecot) in PlaceA with IP_A. And about 6 users are receving mail from the same IP_B( NATed public IP) in PlaceB. Their mails are many( about 1Mb/hour each) and ususally set fetch time as 10min/fetch. Then they complain that their mails often cannot be downloaded. [Reason investigation] I noticed that 1.when one of them fail to fetch mail. All TCP IP connection between IP_A and IP_B will be RST.which means that http/ssh/pop/smtp all not work for a while. And after about 10 minute, the http/ssh can work well. 2.I have asked them to backup and delete pop accounts and use webmail through imap provided by dovecot.And that seems work well but inefficient. I think this maybe because of multi users from one IP address concurrent, [Question] Would you pls provide some suggestion or solution about this issue? Is this a bug of dovecot or just a mis-configuration I don`t know? Thanks in advance for any advice. Best regards, Yi Xuan

[Dovecot] Fatal: EOF while reading environment from master Error
by Phil Bettinson 11 Sep '05

11 Sep '05

Hello all! I guess it's a standard reason for joining a mailing list, but I have a problem. For some reason, whenever I try to start dovecot, be it from the xinet.d or from the commandline, I get this rather bizzare error. I can't even work out what it means, so I can't even begin to debug it. There is nothing extra in /var/log/messages, so I'm out of ideas. I've tried it with the default config, as well as with a config that I adjusted to fit the environment. I'm currently out of ideas. I did notice that there is a brief thread on this in the mailing-list archive, but it doesn't seem to point to a solution. Hopefully someone can help. I'm running it with the command /usr/local/libexec/dovecot/imap-login I am using the 1.0.alpha1 version, running on RedHat AS 3. thanks in advance.

[Dovecot] Dovecot-alpha1 and Thunderbird Sent problems
by Nicholas Young 09 Sep '05

09 Sep '05

I have dovecot 1.0alpha1 setup in a semi test environment running on Solaris 2.6. When using Thunderbird 1.0.6 from Windows occasionally the client will hang after sending a message and before copying it to the Sent folder on dovecot. Sendmail logs indicate that the message has been sent correctly. The mail directory is not shared over NFS. It is in maildir format. Restarting Thunderbird and sending exactly the same message will work. This seems to imply that it is not message dependant. Once the error has occured once it continues to occur until the client is restarted. We have file system quotas however they are very large for a very small amount of mail. The filesystem is about 80% free space and about 98% free inodes. I cannot replicate the issue under Linux using Thunderbird that is current for FC3. Some hacked version 1.0.2-1.3.3 Imap workarounds turned on under dovecot are outlook-idle for imap. The issue has not been seen under Outlook. Outlook is using a local Sent-Items folder instead of an Imap one however. The connection is running over SSL so I can not sniff the traffic on the wire, I have not tried using the rawlog settings yet. I plan to start this now, however the sporadic nature of the problem may delay useful information from here. The dovecot logs are not showing error messages, just: dovecot: Sep 09 09:24:35 Info: imap-login: Login: user=.... TLS Any suggestions on where to start would be great. This issue was not reported to me when running dovecot-1.0-stable-20050718. Thanks for any help/suggestions on where to go from here. -- Nich

[Dovecot] Ip addr + login name
by mike 08 Sep '05

08 Sep '05

Hi everybody, Is there a way to bind client ip address that connects to pop3 with the login name? For example if the client ip address is 192.168.2.40 then his login name is 'test' and he can log in with only that account name. I think it is possible to do it with an external authentication program. Thanks.

[Dovecot] More verbose logging of POP transactions?
by Philip Hallstrom 08 Sep '05

08 Sep '05

Hi all - I'm brand new to dovecot (0.99.14 on freebsd 5) and am just playing with it a bit. POP works just fine, but the only thing that shows up in my logs is this: Sep 7 11:46:25 freebsd5 pop3-login: Login: philip [10.28.61.200] Thought maybe syslog was quietly eating things, but told dovecot to use it's own log file and it didn't improve. Is there a way to turn on more detailed logging about what the user did? Along the lines of what uw-imap's pop gives you in terms of number of messages available, downloaded, deleted, etc.? I'm also interested in how much was transferred size wise... If I mised it in the conf file just let me know, but I didn't see anything... Thanks! -philip

[Dovecot] Dovecot - IMP - POP autentication problem
by Carlos Bergero 07 Sep '05

07 Sep '05

Hi, Recently I have to rush one of my mail servers to a new installation, actually GNU Linux/Debian Sarge, the system run dovecot 0.99.14 for pop and imap, and the web server, other machine, uses horde2/imp3. The problem is the following, pop clients including the imp3 cant log properly apparently, the even when a connection is made to pop3 dovecot trys to make a secure connection, I found this after sniffing the connection between the web server and the mail server, for some reason, imp cant handle it well and the some clients like OutLook also have troubles working this out. For now I work around this problem by disabling the ssl/tsl support, but that's not the solution I need. So the question is can I disable this feature without loosing the secure connection and how can I do it? Cheers, rak

[Dovecot] 1.0alpha1: new assert/core
by Jeff A. Earickson 07 Sep '05

07 Sep '05

Hi, I saw a new assert and core dump today in 1.0alpha1. Setup is Solaris 9, dovecot built with gcc 4.0.1, running as imap server for mbox format. The syslog said: IMAP(user): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) A gdb analysis of the core dump is attached. BTW, I save core dumps in case you need further debugging done for an assert. On another note, I have also had issues with dovecot locking up with "Too many open files" syslog error messages. Last night, after several hours of "too many open files" complaints, the master dovecot process just died -- no core dump and no complaint to syslog. Per advice of the list, I have doubled the rlim_fd_cur and rlim_fd_max kernel parameters and rebooted my imap server. I also saw in my syslog: Sep 6 16:48:53 emerald dovecot: [ID 956436 mail.error] pipe() failed: Too many open files Sep 6 16:48:53 emerald dovecot: [ID 257797 mail.crit] dup2(stderr) failed: Bad file number With students back, they have been giving dovecot a real hard workout.

In 1.0 there are two executables, mail_executable launched for logins, and (from memory) auth_executable launched at daemon start, so I suppose login_executable is the wrong one :-) I diagnose the error you get as meaning that the space is not ed separat out, and that dovecot tries to fork the executable named /usr/libexec/dovecot/popbsmtp.sh /usr/libexec/dovecot/pop3-login which obviously won't work. > Permissions are 777 on the popbsmtp.sh script.

[Dovecot] 1.0-test75 and roadmap for v1.0
by Timo Sirainen 07 Sep '05

07 Sep '05

http://dovecot.org/test/ Keywords are finally stored in maildir filenames and listed in "dovecot-keywords" file. It should be possible to just rename 0.99.x's .customflags file to dovecot-keywords (but it can't be renamed back after modification). Also fixed another uid/sequence mixup bug with setting keywords in general (in mbox too). Fixed SHA1 checksum generation with big-endian machines (used only in passwords). I think I'll forget about the master/config rewrite for a while and leave it for Dovecot v2.0. That would mean the next release will be called 1.0-alpha1. After that there should be only bugfixes and some smaller features and optimizations left. I looked through my TODO and found the following missing features / optimizations that pretty much have to be done before v1.0. Anything important missing? - keywords: - add some limits to how many there can be - send FLAGS/PERMANENTFLAGS untagged replies when they change (required by IMAP RFC) - remove unused keywords from keyword list? (only when adding new ones) - mail cache file - cache _all_ headers that are marked to be cached when headers are being parsed, not just the ones client is requesting at that time. - compression should drop fields with last_used < (latest_mail_index_date - month) - when parsing mbox or saving message, parse the mail through index-mail so things gets saved into cache immediately - mbox - when we're updating flags with lazy writing, we're still parsing the mbox, just not writing to it! - always add empty line after mail. - make the parser require it too? syncing should make sure there always exists two LFs at end of file. raw-mbox-stream should make sure the last message ends with LF even if it doesn't exist in the file - COPY doesn't work to same mailbox (lock assert crash) - keep mbox lock for two extra seconds after sync to make sure we notice changes made by other mbox writer software - maildir - hardlink copying doesn't update indexes (does it even work?) - deliver needs quota integration somehow so it returns out-of-quota failure as fatal instead of temporary Probably after v1.0: - Full NFS support - Try to handle out-of-quota/disk space situations well

[Dovecot] 1.0.alpha1: Namespaces
by Wolfram Schlich 06 Sep '05

06 Sep '05

Hi, I'm currently using 1.0.alpha1 without luck regarding a namespace issue. Maybe it's a general understanding problem on my side, but let's see :-) I would like to have my mail stored in Maildir format below ~/.maildir/, which works fine so far. I want any (sub)folders to be created like this: ~/.maildir/ /cur /new /tmp /.Folder/ /cur /new /tmp /.Subfolder/ /cur /new /tmp BUT ;) Dovecot seems to disregard my namespace settings: --8<--[ /etc/dovecot.conf ]--8<-- default_mail_env = maildir:~/.maildir:INDEX=MEMORY namespace private { separator = / # prefix = # location = maildir:~/.maildir inbox = yes hidden = no } --8<-- Every new (sub)folder I create is stored as ~/.maildir/.Folder resp. ~/.maildir/.Folder.Subfolder in the filesystem. Are namespaces the right way? Is it possible at all? Thanks in advance. -- Wolfram Schlich

[Dovecot] upgrading: should I and what will change?
by Joshua Paine 06 Sep '05

06 Sep '05

I've been running dovecot 0.99.11 with postfix and postgresql in a production environment with about 25 real users and a couple hundred aliases split over a few domains for nearly a year now. No problems of any kind that I have noticed. Should I upgrade to the latest dovecot? What changes, if any, will I have to make? I've looked through the archives for a couple months without seeing much, and I don't see anything specific in the docs about upgrading. -Joshua <><

[Dovecot] how to migrate from one server to another?
by Bram Mertens 06 Sep '05

06 Sep '05

Hi I have purchased and installed a new PC and would like to transfer my mail (in Maildir format) to it. Are there any precautions I must take before copying the mail over? I will disable mail delivery temporarily so no new mail gets written to disk but I don't know if dovecot has to be stopped before copying/editing mail for backup or migrating purposes. Anything else I must pay attention to? TIA Bram

[Dovecot] dovecot + openwebmail
by Peter McEvoy 05 Sep '05

05 Sep '05

Hi, I'm trying to add some sanity to a badly thought out mail system that, for various reasons, cant be fixed from the bottom up at this moment in time. The system is debian sarge, exim 4.5, doing virtual domains and delivering into mboxes in /var/spool/virtual/$domain/$user , there is webmail access and this allows user to create folders in (dont shoot me!) /etc/openwebmail/users/$domain/$username/mail/ , the files in this directory appear to be mboxes in that each mail begins with a From: line, the naming of these files is completely arbitrary. Im trying to add imap access that would ideally give users access to the mail in /var , and also in the openwebmail dirs, though the latter is not essential, just desirable. All mails are owned by user mail. I've installed dovecot-imapd version 0.99.14-1, but if this doesnt have the namespace additions from version 1.0-test, I can easily install that. Reading the wiki, it seems I can achieve this with namespaces, something like namespace private { separator = / inbox = yes prefix = location = mbox:/etc/openwebmail/users/%d/%u/mail:INBOX=/var/spool/virtual/%d/%u } But, Im not quite sure where this would go in the config file, going by the example config you can just shoehorn them into the middle of the file, but I'm not 100% sure... I had been trying to use things like.. default_mail_env = mbox:/var/folders/%d/%u:INBOX=/var/spool/virtual/%d/%u:INDEX=/var/indexes/%d/%n Having created the necessary folders in /var , but I didnt have much success (the authentication part worked straight away using my passwd file), And having read more and been told about namespaces on the irc channel, it seemed like I should go that way anyway. If anyone could give me a steer in the right direction, or even tell me i'm wasting my time (tho dont bother telling me how much better maildir etc is, i know!) Thanks for your time. -- Pete

[Dovecot] dovecot and communitgate (stalker)
by tyco 05 Sep '05

05 Sep '05

hi there, i am totally new to dovecot and use communigate pro stalker.com as my mailserver. everything in communigate is fine. the only problem i do have is imap speed. i just got a login at a dovecot server and i must say WOW its so fast amazing. since communigate does not support indexing on mdir direcotries i need to find a solution. so i am wondering if it would be possible to use dovecot imap server on top of communigate as an imap server? i know that this would not work for special cgp features like shared mailboxes. etc.... thnax christof

[Dovecot] Dovecot 1.0 and ldap; does this combination works?
by Vedran Furac 05 Sep '05

05 Sep '05

Hi! After upgrading from dovecot 0.9.14 to 1.0 crashes immediately after starting when using ldap as userdb and passdb. You can find more information here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=320388 I'm confused with two users: login_user and auth_user. Witch of them has to be in ldap? If anyone here has a working dovecot+ldap configuration, could he show me his configuration? Regards Vedran

[Dovecot] Dovecot-LDA: Development questions
by Steffen Kaiser 05 Sep '05

05 Sep '05

Hello, I'm tinkering with Dovecot-LDA in order to achieve: + Better intergration into sendmail, and + tweaking its way to act on errors. Attached patch is a "brainstorming" like suggestion: a) when sendmail is dropping a message, it spawns the LDA, captures stderr/stdout and, if the LDA returns an exit code != 0, generates either a DSN or, when EX_TEMPFAIL, queues the mail. Hence, it is not necessary to have mail_send_rejection() to spawn another sendmail instance. The attached patch suggest to introduce an "operation_mode", in which Dovecot-LDA behaves differently for different environments. b) Some errors, like when spooling the message into the users folders fails, because the user is out of quota, one should prefer tempfailing the message, rather than a permanent error. Attached patch includes an option "-f", which has main() to return EX_TEMPFAIL. This is the way maildrop is acting, BTW. === Sendmail supports "account+detail" syntax out-of-the-box; that is for recipient matching only the portion left of the plus-sign is significant, the trailing portion may be used by the LDA as a hint to spool the message. Usually the information is passed via command line to the LDA. The libsieve seems to already support this notation, see tokens DETAIL, subaddress, :detail and the README file: Derrick Brashear (shadow+sieve@andrew...) Did somebody used or have some idea how to make use of the "+detail" stuff of libsieve? Basically the main problem in my opinion is what to query, because the information (final physical mailbox and/or owner) one can query is neither a header nor an envelope information (besides that the envelope information is not available to the LDA anyway). Consider a BCC to one recipient that expands to numerous maildrops, then the maildrop of actual delivery attempt can not be derived from neither the envelope nor the header information. The only way to integrate the +detail stuff into Dovecot-LDA seems to be when "keep" is performed (or no Sieve script is present). Then one could spool the message into folder "detail", if it already exists -- one should be allow other people to create mailboxes ;-) This is no action of the Sieve library, but of the LDA calling sieve. The Wiki mentions in the section about to setup exim: envelope_to_add What's this setting is doing? In src/sieve-cmu.c, static int getenvelope, there is: } else if (!strcasecmp(field, "to")) { *contents = m->temp; m->temp[0] = /*FIXME:msg_getrcptall(m, m->cur_rcpt)*/m->authuser; m->temp[1] = NULL; return SIEVE_OK; So it seems appropriate to tweak dovecot_sieve_run() into: mdata.authuser = username; mdata.recipient = detail_on_commandline ? concat(username, "+", detail_on_commandline) : username ; Or better: Have the complete recipient passed via command line option? and alter getenvelope(): m->temp[0] = m->recipient; I think this tweaks would be better than have the "-d" option support the plus-syntax. === Currently, the compiled Sieve script is placed into the same directory the script is located itself. How about to _always_ file the compiled script into [CONTROLDIR]/.dovecot.sievec? That would come over the problem with the system-wide default sieve script. Otherwise: The README mentions a test application and I found a sievec and sieved application (Sieve compile / decompiler) I presume. I can not just run "make sievec" to have it compile, does somebody played around with the Sieve stuff in LDA? Regards, -- Steffen Kaiser

[Dovecot] 1.0a1 Coredumps / errors when moving multiple
by Gregory Bond 05 Sep '05

05 Sep '05

I've just tried upgrading 1.0t51 to 1.0a1 and it has been........ difficult. I've been getting logs of Sig11s and other errors, and have trouble tracking them down. Main problem seems to be with moving / copying messages. One at a time works (mostly), multiple will coredump the imap process (not yet managed to get a proper core out though...) I'm using imap & Maildir, maildir on NFS & Indexes on UFS, Solaris 8. Server is postfix / procmail (delivering pre-sorted into various Maildir folders) and Dovecot 1.0a1. Client is thunderbird on OS/X. If I turn off mbox_copy_with_hardlinks, then instead of a coredump I get a hang and an error message: > IMAP(gnb): Maildir /home/gnb/Maildir sync: UID inserted in the middle > of mailbox (3871 > 3870, file = 1125740849.23189_0.lenford:2,Saa) This is after I've removed all the cache/index files and even all the dovecot-uid files.... I'm back on 1.0t51 for now, but could have another crack at this if there are any hints.

by Black Vette 05 Sep '05

05 Sep '05

Fedora Core 4 dovecot-0.99.14-4.fc4 I'm trying to diagnose some mail issues. I do not believe Dovecot is the problem. If I could see the Dovecot logs, it might be helpful in resolving my issue. In /etc/dovecot.conf I have tried to set the following: log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log I have 'touch /var/log/dovecot.log'. When I try to restart dovecot 'service dovecot restart', it fails and I'm not able to see the reason why it is failing. Where am I going wrong getting this working? Also, are there various debug levels? I saw 'debug' mentioned on the list, but I was unable to see anything about it in the config file. Thanks, Mike __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Re: [Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by Paul Vatta 05 Sep '05

05 Sep '05

Hi Chris, We migrated to Dovecot from Qpopper/UW-IMAP in July. We previously looked at altering the Dovecot code, client-side duplicate email cleanup utilities (for Eudora), and enforcing "download-then-delete from the server" prior to the migration. We got around the "downloading of previously downloaded emails" problem by moving all previously downloaded emails to a new folder called "ConvertedMail" during the conversion process from mbox (Qpopper) to maildir. This assumes you're going to maildir though. The benefit in this is that the POP client only retrieves email from th inbox folder, and after conversion, this will mean only new emails. If the POP client's previous download of older email dissappeared (for whatever reason), a Web Mail client accessing the mailstore via IMAP would allow access to the ConvertedMail folder. Regards, Paul

[Dovecot] login: Missing Protocol from server name 'imap'
by Phil Bettinson 04 Sep '05

04 Sep '05

Hello All (possibly again) I did send a messge earlier, but it may have been eaten by the mail system. I've now managed to get dovecot started, and I'm now getting "Missing protocol from server name 'imap'" This is somewhat confusing. Does it mean that I have somewhere called my server imap? or is it talking about it missing a protocol called imap? if it's meant to be "missing protocol imap definition" or somesuch, I have filled that out, but can't for the life of me figure out what the error message is actually trying to tell me! I'm running dovecot alpha1 on RedHat as3. I have the feeling I've been staring at the problem for too long, and somone will just say "have you tried this!", but it's worth a shot. Thanks in advance Phil

[Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by grant beattie 04 Sep '05

04 Sep '05

hi all, I am hoping to convert a 350K user qpopper installation using mbox to dovecot and maildir (pop3 only). many of the users "leave mail on server", and qpopper's UIDL format isn't (yet) supported by dovecot. since the UIDLs have been written by qpoppper to the existing mbox files (and will be preserved when the mboxes are converted to maildir) it would be possible to do this seamlessly if dovecot could read the UIDLs from the messages and populate the index files as needed. is anything like this already possible? it doesn't matter what UIDLs new messages get, since they would never have been downloaded by the user via qpopper. any ideas would be appreciated. grant.

[Dovecot] Purge / Delete Problem using IMAP
by A Ve 03 Sep '05

03 Sep '05

Hi, I am using dovecot 0.99.14 RPM on a Fedore Core 4 Server. Everything was running fine for weeks (IMAP), and 2 days ago I was not able to delete/purge any Mail in INBOX. I am using Outlook 2003 as an IMAP-Client. I tried to delete/purge the Inbox with other mail-clients (Mozilla Thunderbird, Mulberry) too, same effect: I can read mail, I can copy them by drag-n-drop to a local Client-Folder (eg: Outlook) , but I can delete them. Strange enough, the mails are marked as read, but when I login again, all Mail are marked as new/unread ! When I log to the node, and start mutt (which is using the spool-file /var/spool/mail/username), then I am able to read-n-delete all Mails... The File Permisson of the File: 755, Owner: Username, Group: Mail. Did I miss something ? How can this stop working from one day to another ? I seems to me, like the INBOX is not writable to me ... From the UNIX Side, it is ... :-/ Any Comment/Feedback would be helpfull. This is really strange. Regards, AVE.

[Dovecot] string expansion *in* dovecot config?
by OpenMacNews 03 Sep '05

03 Sep '05

hi all, is it possible to define/use 'MACROS' (string expansion, ala Exim) in dovecot's config file? specifically, e.g. -- rather than: login_executable = /some/crazy/path/to/dovecot/libexec/dovecot/imap-login i'd LIKE to do something like MY_PATH = /some/crazy/path/to login_executable = MY_PATH/dovecot/libexec/dovecot/imap-login i'm reading the wiki docs, and it's just not obvious to me ... thanks! richard

[Dovecot] Weird internaldate behavior with 1.0-test80 and mbox folder
by Jon Roma 03 Sep '05

03 Sep '05

Has anyone else encountered weird date behavior with mbox-style folders? I am nearly ready to bite the bullet and convert my UW imap hierarchy (which is in mbx format) to Dovecot. In so doing, I need to convert each UW-specific mbx-format mailboxes to the more portable mbox format, which Dovecot can read. (This is done with the 'mbxcvt' utility that's part of UW.) I am then planning to copy those mbox-format folders into a staging area in a directory I've defined to Dovecot as a mbox-format namespace. The plan was then to use my normal GUI to reorganize my old data and copy it into proper maildir folders into Dovecot's default namespace. Since I'm naturally paranoid, I did a dry run of a couple folders first and discovered a rather strange anomaly -- all the mail in the converted folder is displayed by Dovecot with a timestamp exactly 200 minutes (3 hours 20 minutes) into the future! Investigating this via telneting to the respective IMAP ports shows that UW imapd shows the correct timestamp both in the original mbx-format folder and the converted mbox-format folder -- so it appears that Dovecot is skewing the time. This doesn't look like a timezone issue since 200 minutes ahead from CST6CDT would be a pretty strange timezone -- not even Newfoundland has this odd a TZ value! :) (For the curious, Newfoundland is a Canadian province whose time zone is TZ=NST3:30NDT, therefore being a half-hour "off" from the rest of North America.) I have distilled this into a degenerate case of a single folder with a single message and can reproduce. As mentioned, I am running 1.0-test80. My platform is AIX 5.1. I created the test by sending a message to myself using date | mail -s "Test at $(date)" roma(a)uiuc.edu and using my MUA (Mulberry) to file it into the test folder, which defaults to mbx format in UW's namespace. Here's what UW shows when I select/fetch the "original" message: * namespace * NAMESPACE (("" "/")("#mhinbox" NIL)("#mh/" "/")) (("~" "/")) (("#shared/" "/")("#ftp/" "/")("#news." ".")("#public/" "/")) * OK NAMESPACE completed * select "~/Test" * 1 EXISTS * 0 RECENT * OK [UIDVALIDITY 1124811965] UID validity status * OK [UIDNEXT 3] Predicted next UID * FLAGS (\Answered \Flagged \Deleted \Draft \Seen) * OK [PERMANENTFLAGS (\* \Answered \Flagged \Deleted \Draft \Seen)] Permanent flags * OK [READ-WRITE] SELECT completed * fetch 1 internaldate * 1 FETCH (INTERNALDATE "23-Aug-2005 11:16:37 -0500") * OK FETCH completed * fetch 1 envelope * 1 FETCH (ENVELOPE ("Tue, 23 Aug 2005 11:16:30 -0500" "Test at Tue Aug 23 11:16:29 CDT 2005" (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) ((NIL NIL "roma" "uiuc.edu")) NIL NIL NIL "<200508231616.j7NGGUrc022618(a)zippy.cso.uiuc.edu>")) * OK FETCH completed Next I use the UW 'mbxcvt' to convert the folder, leaving it in mbox format in a different folder (~/Test-mbox) -- still in UW's namespace.

[Dovecot] (no subject)
by Phillip Needham 02 Sep '05

02 Sep '05

I am trying to get away from courier imap because it is flaky the way it uses FAM (or gamin in my case), and the developers seem to have a chip on their collective shoulder, and it is too complex. I found dovecot because it is ships with CentOS 4 (ie Red Hat Enterprise 4). It looks like just what I need: simple, fast. But I can't use it! I can't authenticate. If any of these statements were untrue, I would use it happily: o it doesn't support simple bind authentication against LDAP o I don't want to make passwords readable, and this version (0.99.14) doesn't support SSHA anyway o it won't talk to the saslauthd I already have configured o I can't find how to implement a new auth module for dovecot I am wondering why, in the quest to fill a niche with a simple, fast, secure IMAP server, the authors felt the need to re-implement a robust and well-tested infrastructure (saslauthd) with a less-featureful and untested one?

[Dovecot] Dovecot imap with Postfix and using Thunderbird as client
by Ben Ware 02 Sep '05

02 Sep '05

Hi, I just recently installed dovecot, and I am having the following problem: If I send an email to my account on this new machine, I can log in via SSH and use the unix mail command, and instantly my email is visible. If I turn on Thunderbird, it will show my new message. If Thunderbird was already on and had already checked the mailbox, even if I click on get new mail for that specific mailbox, the new mail does not show up until I restart thunderbird. Is there something that I have set wrong in the config files that is preventing the IMAP part of dovecot from refreshing the messages quickly for me to see? I dont see anything in the log files at all except for it showing me logging in. Thanks, Ben

[Dovecot] 'Bind'-method authentication for LDAP
by Phillip Needham 01 Sep '05

Has there been any thought given to implementing authentication via an LDAP 'bind', rather than by a password lookup and hash comparison? doing a bind would obviate the need to make the passwords readable by the dovecot process and would lend itself to improved security.

whaooo that is interesting, Thank you so much for the explanation. I guess my choice now is to go with maildir as Blairpoint out because I am running in single host mode.

I'd say it depends, I'm working with clustered filesystems in SAN environments where mbox is significantly faster than maildir since single mbox file generates much less overhead in form of distributed file locking accross cluster nodes. On single host systems with good file system I'd probably go with maildir. Maybe someday I'll manage to do some benchmarking between mbox and maildir with Dovecot. -- Tomi Hakala

Lisandro Grullon wrote: > What method for mail boxes are you guys using mbox or maildir and which one would you recommend? Thanks. I use maildir because it stores each message in a separate file. So this gets me: 1) Daily backups of a ~/Maildir are much smaller than a large mbox because most files don't change, while a single change to a large mbox file will require the entire mbox to be backed up. 2) Moving emails from folder to folder is much faster, as it's moving a single file and you don't have to delete an email from a middle of a mbox file. I have a 5 year old 450 Mhz Dell that easily and quickly manages over 2 Gbytes of email for several users. Regards, Blair

[Dovecot] Oddities with Debian unstable dovecot
by Blair Zajac 31 Aug '05

31 Aug '05

Hello, I'm running an Debian etch box with unstable and ever since the last upgrade to dovecot, I've seen odd things. At times, I would see emails would go missing from the Inbox or other folders, and I couldn't move emails that were moved from the Inbox to another folder back into the Inbox. These have seen gone away since I removed all dovecot.* files and .index* files from my Maildir's and let Dovecot regenerate them as needed. The most current thing are these errors: dovecot: Aug 30 11:38:33 Error: IMAP(blair): file mail-transaction-log-view.c: l ine 183 (mail_transaction_log_view_set): assertion failed: (max_file_offset == ( uoff_t)-1 || max_file_offset <= file->sync_offset) dovecot: Aug 30 13:05:21 Info: imap-login: Login: ashley [127.0.0.1] dovecot: Aug 30 13:14:06 Error: IMAP(ashley): Corrupted index cache file /home/ashley/Maildir/dovecot.index.cache: record points outside file Anything I can do to help here? I don't have a core file, even though I have 'mail_drop_priv_before_exec = yes'. The other odd thing I noticed is after running /etc/init.d/dovecot stop, I would have several imap processes left over in my uid. They don't do much: # strace -p 5014 Process 5014 attached - interrupt to quit gettimeofday({1125460345, 997748}, {420, 0}) = 0 gettimeofday({1125460345, 998465}, NULL) = 0 poll([{fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 410) = 0 gettimeofday({1125460346, 410768}, {420, 0}) = 0 gettimeofday({1125460346, 410890}, NULL) = 0 poll([{fd=8, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 0) = 0 gettimeofday({1125460346, 411940}, {420, 0}) = 0 gettimeofday({1125460346, 412551}, NULL) = 0 However, lsof shows that the file descriptor 8 is a pipe back to fd 9 in the same process.

[Dovecot] dovecot/pop-before-smtp
by Micah Stevens 31 Aug '05

31 Aug '05

Hi, This is off-topic I know, but if anyone has any suggestions, I'd appreciate it. I'm running postfix 2.2.x, dovecot 0.99, and it's working great, I wanted pop-before-smtp functionality, so I fired up the suggested perl daemon in the dovecot docs.. This seems to work, I ran tests, it was picking up the ip's, putting them in the .db file, and postfix was able to read them. My issue is that it doesn't seem to continue to do this. It only works if I force it with a --reprocess flag. At that point, the latest set of ip's get inserted in the database, and all is well. Any ideas? I did check to make sure the daemon is running, and it is. Thanks! -Micah

[Dovecot] Recommended dovecot version
by Diego M. Vadell 31 Aug '05

31 Aug '05

Hi, I'm running CentOS 4 in a X86_64 server with dovecot. I've been having some (already reported by others) problems. For example, sometimes - randomly - a mbox file wil get a couple of lines at the beggining of the mbox file (/var/spool/mail/user), before the first From line, and dovecot will complain that that file is not a mbox file. Also, neither sylpheed nor thunderbird would get new mail via imap a second time (I have to kill thunderbird, then run it again so it would give me the new mails). But I'm more concerned by the mbox corruption. so I want to upgrade, but to what? 0.99.14? But in www.dovecot.org says that dovecot-1.0 is recommended. But it also says -alpha! (not even beta: alpha). There is also a stable branch, but it's not the recommended one (or is it?). Can anyone point me to a stable version that addresses the mbox corruption issue, or if there isn't such a version, any idea of when it will be ready? Thank you. -- Diego.

[Dovecot] Multiple mailbox formats, per-user mailbox format support
by Ragnar Rova 30 Aug '05

30 Aug '05

Hello, I have a setup where each user has different mailbox formats (some use only /var/spool/mail/user) mailbox format, some is stored in mbx format ~/INBOX or ~/mbox and some is stored in maildir format in ~/Mail/ I currently use UW-IMAP to read /var/spool/mail/... and the mbx format mailboxes in ~/INBOX and mutt to read ~/Mail/... (the maildirs in ~/Mail/ are created by procmail rules) Does dovecot make it possible to also read the maildir directories i have in ~/Mail/ without having to reconfigure the delivery/imap system for all users? I know I should migrate to use one consistent mailbox format (thinking about maildir), but to avoid any migration It would be great if dovecot just would be able to read multiple inboxes in different formats differently configured on a per-user basis. I use postfix for delivery/transfer.

[Dovecot] quick, quick, slow...
by Jeroen Scheerder 30 Aug '05

30 Aug '05

Hi, I'm (still) evaluating dovecot for a switch from UW in the near future. All the following happens on a Solaris server. Functionally, all is well. However, I see strange phenomena. Normally, dovecot is pretty swift. Every now and then, though, things slow down to a crawl. Everything seems to be working, still, but a few orders of magnitude slower. A copy of an outgoing message (of a few lines) to my Out box, which normally succeeds nearly instantly, suddenly takes over 30 minutes, for example. Obvious things to look for would be conflicting locking strategies. As far as I know, though, my mail delivery agent (procmail) and all mail handling software use dotlocking, fcntl lockf, in that order), as does dovecot. In syslog there's nothing to see, except an occasional SSL_accept() syscall failed: EOF messsage, which I can correlate to my service monitoring software (nagios), which checks for the presence of the imaps service. When this happens and I quit my mail agent (Thunderbird), an imap process seems to remain on the server. Killing that does not resolve the extreme slowdown; that persists on consecitive reruns of my mailer. I'm at a loss here. Any hints?

[Dovecot] Wiki of dovecot.conf file
by Tim Schaefer 30 Aug '05

30 Aug '05

Thanks but that was of absolutely no help. Evidently the 1.0alpha version syntax is completely different from the .99 release. The 1.0 syntax for setting up dovecot.conf uses brackets "{}" for auth and other drastic differences, so most of the documentation is either vacant or out of date. I tried using the syntax used in the Wiki only to have it die. There are NO docs for the 1.0 release to help understand how to make MySQL work with Dovecot. I've hacked my way along and stumbled into some success, but overall I'd have to say there is a bug in the software that is preventing it from connecting. I do not know where else to look or what else to do other than start to hunt again for yet another pop server. I've spent the past week downloading, compiling, and trying to get various POP servers to work, only to have the wheels fall off at one point or another. I'm so fu**ing close to getting Dovecot to work, but may have to walk away from yet another disappointing software product. I might downshift to the .99 release and see if I can get that one to work. But thanks anyway for your desire to help, it prevented me from leaving a note and then pulling the trigger. :-) Tim

[Dovecot] imaps only, and on a nonstandard port?

[Dovecot] Feature Request - wild idea - folders for executing programs
by Marc Perkel 29 Aug '05

29 Aug '05

Timo, I have a wild idea for a feature that is somewhat unusual, would be very powerful, and easy to implement. What I want is ... Special folders that when someone drags a message into them - it pipes the message into a program. The reason I want this is - for example - reporting of spam. Suppose you want everyone to have a spam-missed folder so that if a spam gets through then the user drags it into the spam missed folder. But instead of storing it there it executes a program and pipes the message into it. In this case a learner program for the spam filter. The folder would be "write only" and attempting to read the folder would generally look like it was empty. Setup would look like this: executable-folder spam-missed { command = /usr/bin/sa-learn spam user = spamd group = spamd create_folder = yes accounts = * } The "create_folder" command says to add the folder to the users lists whether or not it is physically there. The folder appears even if there is no real folder. If it is "no" then it only exists if there is a real folder. The "user" and "group" is of course the UID and GID to run the "command" as. The "accounts" determines which accounts are affected. Default is everyone. Other uses is to control blacklists and whitelists. Dragging a message into the blacklist folder runs an executable that adds the sender to a blacklist, or a whitelist, or controls settings etc.

[Dovecot] Sig11 and some corrupted indexes after 1.0-stable -> 1.0.alpha1

[Dovecot] Dovecot 1.0 alpha trouble on OS X
by Lars Skovgaard 29 Aug '05

29 Aug '05

Hi all! I've just upgraded dovecot from 0.99 to 1.0 alpha, and it seems to be working perfectly except for a strange problem with one of my imap- users Inbox. Every folder is accessible, including the Inbox. The inbox currently contains five mails. With at least three of these, when they are attempted moved, dovecot crashes immediately with the message "Unable to determine CPSProcessSerNum pid: 12345 name: imap". The destination folder seems to be of no importance. I can copy or move these mails from the command-line, but not from the mail-client. I can, however, open them and read them from the Inbox using Apple Mail or SquirrelMail, as well as from the command- line. I've checked the privileges, and the mails belong to the user and have the appropriate rw-privileges. Any new incoming mail seems to be accessible as expected, and can be moved as desired. I apologize if this has already been discussed, but I've searched the archives without finding anything. Best regards Lars Skovgaard

[Dovecot] mail directory error solved!
by Micah Stevens 29 Aug '05

29 Aug '05

Hi, I figured out my issue, in my database query for the mail dir, I was grabbing the home column instead of the mail column. Once I changed the name of the column returned it started working. Currently my queries are like such: password_query = SELECT `passwd` FROM users WHERE userid = '%u' and user_query = SELECT concat('/usr/local/virtual/',maildir, '.INBOX') as mail, 101 as uid, 103 as gid FROM users WHERE userid = '%u' My question now is currently I'm saving mail like this: mailroot/domain/user/.INBOX I assume I should be able to save it as: mailroot/domain/user/ the .INBOX is superfluous, is that correct, or will imap want to make directories at the same level at inbox?

[Dovecot] Success: MySQL Works on 0.99 But Not 1.0alpha
by Tim Schaefer 28 Aug '05

Great news! yay! I downshifted to dovecot 0.99-14 and pop server is working! Finally a pop-server and postfix and all! And no Courier! or Qmail! Whatever changed in the 1.0 release regarding MySQL is broken, and is working in the .99-14 release. I can finally use my mail server! :-) I'll keep an eye out for the 1.x stable release, hopefully it will have MySQL support working. Maybe by then I'll be brave enough to get IMAP working and maybe even ( gulp ) LDAP. Good Luck to all of you! Timo go go go ! Tim

[Dovecot] Authenticate user thru PAM
by Adrian Mak 28 Aug '05

28 Aug '05

my mailsystem is using postfix and virtual mailbox which stored in mysql db. SMTP AUTH is using PAM, pam-mysql to authenticate against a mysql db. I installed dovecot 0.99-14. In the dovecot example config file it mentioned that auth_passdb can check against thru PAM but auth_userdb didn't Does it mean that auth_userdb should use other means e.g. /etc/passwd, shadow, vpopmail, etc and in my case it is mysql. Right ?

For example: userdb passwd { default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u } # Linuxconf passwd-like file with specified location userdb passwd-file { args = /etc/vmail/passwd.%d default_mail_env = mbox:/vhome/%d/home/%n:INBOX=/vhome/%d/home/%n/INBOX:INDEX=/nobackup/imap-cache/%d-%n } Is this possible? If not - perhaps it should be? -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] Authentication with encrypted passwords
by Sebastjan Trepca 28 Aug '05

28 Aug '05

Hello, I have a postgresql database which contains users that will access dovecot, but their passwords are hashed and I don't have them in plain text. I was reading documentation that you can add tell dovecot which password scheme should it use. For example: password_query = "select '{MD5}'||password from users where userid=%u" Which would mean that dovecot will hash the password with MD5 from client and match it with the one in database. Did I understand this correctly ? Thanks, Sebastjan

[Dovecot] Namespace Feature
by Marc Perkel 28 Aug '05

28 Aug '05

I've never used namespaces and don't quite know what they do. If I add a namespace then do things like shared folders magically appear to users? Also - I wonder if this is possible. I'd like to create a write only shared folder. I know this is unusual but I have a reason. I'd like to have a folder that people can drag spam into to report missed spam. I want to write only so people aren't reading each other's spam. I have a bot that comes by and reads this to train the bayesian filter. Right now I have to create these folders individually. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] Postfix/Dovecot
by Micah Stevens 28 Aug '05

28 Aug '05

Hi, I searched through the maillist archives and the docs, but didn't find anything that directly addresses my question, so here goes if anyone has some time to address it. I'm running a redhat el3 server, with Postfix as the MTA, and I'd like to setup Dovecot to provide IMAP/POP3 services. Postfix uses MySQL lookups to do mailbox lookups, and I configured dovecot to do the same thing. The mail is delivered to /usr/local/virtual/<domainname>/<end.address>/ in maildir format by Postfix. This is working fine. I've setup dovecot, and set it do user auth and user lookups to MySQL. This seems to be working fine as I get no mysql errors from the queries, and my login process (to IMAP from localhost) is fine. Here's a typical scenario: telnet localhost imap Trying 127.0.0.1... Connected to localhost.domain (127.0.0.1 <http://127.0.0.1>). Escape character is '^]'. * OK dovecot ready. 1login micah(a)9250x.com "rigid2" 1 OK Logged in. 2 select INBOX 2 NO If I look in the directory for micah(a)9250x.com I find: # ls cur new tmp The permissions are 777 for now to eliminate that possibility. The dovecot log file lists: imap-login: Aug 28 12:27:11 Info: Login: micah(a)9250x.com [127.0.0.1<http://127.0.0.1> ] each time I log in, and nothing after that indicating why it's not seeing any mail. Why isn't it seeing any mail? Do I need to make an Inbox directory and tell postfix to deliver there? From reading the docs, having the delivery into the main maildir directory should be okay, but I might be mis-reading. Any thoughts would be much appreciated.. Thank you, -Micah

[Dovecot] Permission denied changing to mail directory
by Chris Hogan 28 Aug '05

28 Aug '05

I have 3 domains using one mail server. I've set the dovecot mail directories to be /mail/mail/%d/%n When someone logs on, dovecot attempt to navigate to the domain directory first & we get a permission denied, and we get no further. Its very odd because (a) it was working up until 16:50 on Thursday & (b) the directories now have 777 access. Each user is (at present) a separate unix user & the directories are owned by root & have a file group of mail. I would have thought that the 777 access would have been enough. I don't know what we did on Thursday evening, but any ideas about how to fix the permissions problem? Chris

[Dovecot] Dovecot and Active Directory Authentication
by Dave Smith 28 Aug '05

28 Aug '05

First off, sorry if this has been asked before - I have looked, honest. Is it possible to get dovecot to authenticate users against active directory, treating the AD as a plain ldap server? I have this working with cyrus saslauthd. Currentlt I get a long delay (30 seconds or so) then * BYE Disconnected for inactivity. All I get in the maillog is imap-login: Disconnected: Inactivity [::ffff:127.0.0.1] I am using dovecot-0.99.11-2.EL4.1 on CentOS 4. If anybody has got this to work then please let me know - otherwise I will be forced to use Cyrus........ Cheers Dave Smith

[Dovecot] Dovecot Delivery Bug
by Marc Perkel 27 Aug '05

27 Aug '05

Ran into an interesting bug in Dovecot delivery. A friend forwards an email to me as an atachment. When I receive it - it comes in as two separate messages. One is the forwarding message which is empty, and the other is the original message that was forwarded but it comes in as if I had got the email directly. If I use exim to deliver the message to the mailbox it works. But when exim pipes the message into dovecot deliver it gats split. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] Wiki of dovecot.conf file
by Tim Schaefer 26 Aug '05

26 Aug '05

What would be extremely helpful is a really clean explanation of how to set up connections for MySQL. It would have to start with basic information and some real-world examples that make no assumptions, and clearly spell it out without confusion. In fact good examples reduce the need to subscribe to mailing lists and ask dumb questions! The current assumptions in the docs to date are that somehow non-geeks and those of us who have learned far more about email servers than we ever wanted to will somehow "get it" without decent examples. This has got to be the biggest problem using Dovecot. I've tried just about every pop-server I can find and I am about to give up on Dovecot if I can't get the connection to MySQL to work. I just want decent pop server that understands Maildir, now that I went through Cyrus SASL hell and got that working--again with incredibly poor documentation. And I don't give a rats-ass about IMAP, just need a pop server. Maybe IMAP later, for now just a pop server that understands Maildir and comes from open source. I'm using Postfix but it shouldn't matter. So far I've tried the following pop servers: nupop-1.3.9 -- can't compile qmail-1.03 -- a f**ing nightmare cyrus-imap/pop -- poor-to-no docs for pop server -- another nightmare vm-pop3d-1.1.6 -- works only on mbox flexpop-1.0.1 -- no docs , doesn't compile popular-1.5.5 -- docs are too sketchy for installation, too complicated and doesn't work I thought Dovecot would be the last one I have to screw with, but maybe I'm wrong...

[Dovecot] Dovecot.1.0.alpha1+mysql+mysql
by jigen 26 Aug '05

26 Aug '05

Hi, we are trying to track down the problem that prevents two mysql password databases from working. Instead of connecting to each database, it looks like dovecot tries to connect *twice* to the second specified. Do do this we just inserted some i_warning()s in the code. We noticed that passdb_sql_init (auth/passdb-sql.c) is called twice, once per configuration file, with the correct argument (path to config file). However, as you can see in the following maillog piece, this function calls sql_connect with the SAME parameters (the parameters of the second database). So the first call works and dovecot connects to the host correctly (lines 7-8), but in the second call dovecot finds the connection already up and obviously doesn't try again (last line). Could this be the origin of the problem? Now we are trying to understand why the argument to sql_connect isn't updated correctly. Maybe a bug in the linked list of sql_connection's? [...] dovecot: auth-worker(default): passdb_sql_init("/etc/dovecot/dovecot-mysql_django.conf") [...] dovecot: auth-worker(default): now calling sql_connect(passdb_sql_conn->db): [...] dovecot: auth-worker(default): passdb_sql_conn->config_path="/etc/dovecot/dovecot-mysql_debord.conf" [...] dovecot: auth-worker(default): passdb_sql_conn->set.connect="host=debord port=3306 dbname=posta_debord user=posta password=foobar" [...] dovecot: auth-worker(default): driver_mysql_connect: host=debord, user=posta, password=foobar.

[Dovecot] Dovecot Virtual Users & Sendmail
by Chris Hogan 26 Aug '05

26 Aug '05

Not directly Dovecot, but a configuration problem. We have a working set-up with Dovecot+Procmail+Sendmail, using POP-before-SMTP. We want to be able to offer email accounts to some local schools, using SquirrelMail (keeps their costs & maintenance down). The whole arrangement is working, but we don't want to have to have 300+ School children as users of our Red Hat Enterprise server, so I've set up a passwd style file for authentication. This all works fine, they can access mailboxes & send emails, but to receive Sendmail is checking that they are unix users & bounces messages back if they aren't in /etc/passwd too. Has anybody ever got Sendmail working with Dovecot virtual users? Or is it time I switched to Postfix? Chris Hogan

So if it happens, it's Mysql library bug. It isn't a bug of mysql or dovecot. It's the most simple problem: mysql permissions :P In mysql 127.0.0.1 and localhost are differents things, and if you copy the user (posta in my case), it doesn't copy the password (and so it works without a password).

[Dovecot] Thread sorting problem
by Greg Trounson 24 Aug '05

24 Aug '05

I've just installed Dovecot on a Debian Sarge machine and am seeing some very strange thread sorting. In Mozilla Mail and Thunderbird on both Fedora and Debian clients my threads served up by Dovecot look like this (number denotes message time): |-11 | `-12 |-2 |-3 |-4 | `-5 | `-6 | `-7 | `-8 |-1 `-9 `-10 Where the exact same threads served by Sendmail/imap look like this: |-1 |-2 |-3 |-4 | `-5 | `-6 | `-7 | `-8 |-9 | `-10 |-11 | `-12 Squirrelmail shows the threads correctly in both cases too, so I suspect there might be something funny going on with how Thunderbird handles Maildir threads. I notice that Dovecot doesn't support the THREAD=ORDEREDSUBJECT capability, might that have something to do with it? thanks, Greg

[Dovecot] Dovecot Deliver?
by Marc Perkel 24 Aug '05

24 Aug '05

I guess Dovecot has an LDA called deliver. What is it and how do I use it? Or is it ready to be used. can't find any docs on it. -- Marc Perkel - marc(a)perkel.com Spam Filter: http://www.junkemailfilter.com My Blog: http://marc.perkel.com

[Dovecot] public/private email accounts
by Ashvin Meetoo 24 Aug '05

24 Aug '05

Hi, I am running FC4 with postfix/dovecot/amavisd-new etc on my box with 50 staff email accounts (say 10 per 5 departments)... everything is working ok... I want to create 5 more accounts for each department (to be redirected to respective staffs, e.g. sales(a)xyz.com) as well one for everyone... that can be easily done by creating an account and modifying the .forward file in the /home/<user> folder. My great concern is that if by a virus attachment or spam is not detected and sent to everyone(a)xyz.com, it will be replicated to 50 email addresses... what I want is to have the 6 accounts mentionned above to be used only by the personnel and not the outside world... is there a way of doing this? Thank you. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[Dovecot] Well, "Hard filesystem quota can also be problematic"
by Jeroen Scheerder 24 Aug '05

24 Aug '05

"Hard filesystem quota can also be problematic", quoth <http://www.dovecot.org/>. Since we actually use quota for our userbasg, this merited further investigation. Using 1.0-stable, we enabled quota on /var and /users filesystems, and set very low quota for a test account. Then we had some mail delivered on it, and we moved some messages about. At some point, Thunderbird started to croak about "The current command did not succeed. The mail server responded: Internal error occured. Refer to server log for more information. [<timestamp>].", "The current command did not succeed. The mail server responded: .", "The current command did not succeed. The mail server responded: Out of disk space." This I can live with. Hoever, at some point in our experiments we also found that a mailbox (mbox format) that did contain a few dozen messages suddenly was truncated to 0 bytes. Not so hot. Can anyone tell me whether or not there is, or will be, some way of using dovecot on a system with quota without risk of data loss when quota limits are reached? How do people cope with this? Regards, Jeroen. p.s. That first error message gave rise to the enclosed patch. diff -r -c1 dovecot-1.0-stable-patched/doc/auth-protocol.txt dovecot-1.0-stable/doc/auth-protocol.txt *** dovecot-1.0-stable-patched/doc/auth-protocol.txt Wed Jul 27 08:08:35 2005 --- dovecot-1.0-stable/doc/auth-protocol.txt Mon Jan 31 17:37:54 2005 *************** *** 171,173 **** !

[Dovecot] pop-before-smtp in SQL?
by Lorens 23 Aug '05

23 Aug '05

I need pop-before-smtp (let's not discuss the advisability of the method), but I'm annoyed at the inefficiency of the classical perl script that parses the logs. A long time ago I modified the perl to add the tuple (IP, time) to an SQL table that the MTA looks at, and to clean up periodically. I found that this was the best way to deal with multiple servers that have to share an SQL database anyway. Wouldn't it be quite trivial to make dovecot write to an SQL table upon sucessful login, instead of all this log file parsing by an additional daemon?

[Dovecot] Poprelayd released for Dovecot
by dan1 22 Aug '05

22 Aug '05

Hello all. I just wanted to tell you that poprelayd is now compatible with Dovecot. I have just created a parser for the Dovecot server. This might be interesting either for you or your future customers. Maybe you will want to make some advertisement for it ? I remind that poprelayd is a service that allows a POP user to use the SMTP server of the same machine to send e-mails (making relays) for 15 minutes long after the pop login. This comes very handy for people wanting to send e-mails through their servers and also for a larger use. If you could try it that would also give some interesting feedbacks. This is the link: http://sourceforge.net/forum/forum.php?thread_id=1338704&forum_id=21494 BTW, I would need something from you: The POP login information that we can find for Dovecot in the /var/log/maillog is [::ffff:IP_ADDRESS]. Here is an example: Aug 19 23:23:02 anoigo pop3-login: Login: john [::ffff:82.208.12.243] Will this be kept the same all the time or is this ffff value a variable ? Will it be kept like this all the life of Dovecot ? Also, I would need to know if the 'pop3-login' and 'Login:' information there will also be kept. Thanks. Regards, Daniel

[Dovecot] Re: Dovecot inotify problem

Hi Reuben, I hope you don't mind me copying the dovecot list again. > dovecot: Aug 21 04:08:22 Error: IMAP(reuben): inotify_rm_watch() failed: > Invalid argument Odd. > This is with a 2.6.13-rc6-mm1 release.

Thanks for the link. I don't think akpm is right, unless something is really odd here. Could you add debugging output for me please? Maybe something like (this is not a patch you can apply, look at line 164 in src/lib/ioloop-notify-inotify.c) ctx->inotify_fd = inotify_init(); + i_warning("inotify_init returned fd %d", ctx->inotify_fd); if (ctx->inotify_fd == -1) { and line 106: IN_CLOSE | IN_MODIFY); + i_warning("inotify_add_watch returned %d", watchdescriptor); if (watchdescriptor < 0) { and line 145: } + inotify_rm_watch("removing wd %d from inotify fd %d", io->notify_context, ctx->inotify_fd); if (inotify_rm_watch(ctx->inotify_fd, io->notify_context) < 0) Or something similar. If that doesn't help and output looks consistent (we're not removing a watch descriptor from a wrong fd etc.), can you try removing the fd_close_on_exec call please (line 171)? I don't know if that could cause trouble (I don't even think that the imap binary ever forks) but you never know. johannes

Dovecot IDLE problem (was Re: [Dovecot] inotify support in dovecot)
by Reuben Farrelly 22 Aug '05

22 Aug '05

Hi, I've come across some possibly buggy behaviour with regards to Dovecot and the use of the IDLE keyword. Found this while testing out inotify support for Johannes - although after asking him and him reproducing it, he is of the opinion that it's not a inotify specific problem. The behaviour is that when the client is idling, Dovecot seems to only alert to the first new message received, and if a subsequent new message comes in before the client finishes idling, that second new message is not notified to the connected client. To reproduce: $ maildirmake /tmp/imap-test $ cat >/tmp/1 <<EOF From: test To: test Subject: test test! <Ctrl-D> $ MAIL=Maildir:/tmp/imap-test /usr/libexec/dovecot/imap ... A SELECT INBOX B IDLE [now, in a different terminal, copy /tmp/1 to /tmp/imap-test/new, you should instantly be notified of it in your imap session] ** Dovecot correctly responds with: * 1 EXISTS * 1 RECENT [if a second message is delivered, eg by copying /tmp/1 to /tmp/imap-test/new/2 then you should be notified as well, but this never occurs] DONE C LOGOUT $ Timo - what do you think? Reuben
