[Dovecot] Some of my IMAP Folders vanished in some MUAs
by Dominik Schulz 05 Aug '07

05 Aug '07

Hi, I'm using dovecot for some time now. Previously I was using Courier and I've migrated this setup to dovecot which went pretty fine. Now I'm experiencing some strange behaviour when using some newer mail clients. Some of my Folders, like "spam", are vanished. The strange point is that it only happens in some clients, like Thunderbird 2.x+ or KMail 3.5.x. In others, like Thunderbird < 2, Mutt or my Webmailer (Horde) they still show up. These folders are still there, i.e. in the filesystem, and the permissions seem to match those of the other folders which can be seem in all MUAs. I don't know if this is even related to dovecot but I think this is where I should start looking for an solution. I'm using dovecot 1.0.rc15 from Debian (stable/etch). It'd be great if anyone was able to help me. Thanks in advance. Best Regrads Dominik Schulz

[Dovecot] Password Encryption
by Dave Morrow 05 Aug '07

05 Aug '07

Hi all. I hope this is not a RTFM-type question, but I've been unable to find a searchable archive of this mailing list....... I recently began investigating using Dovecot/Postfix/MySQL solution. I've been following the documentation http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL?highlight=%28m ysql%29 While everything seems to have gone right, I have been unable to successfully login to the IMAP server using Outlook Express. It seems that the problem may relate to PostfixAdmin storing passwords in the mysql database md5 encrypted, and Dovecot is not able to read them, but I am not certain. The error when a client logs in is something like dovecot: auth-worker(default): plain_md5_verify(testuser1(a)mydomain.com): Invalid password encoding David Morrow Technical Systems Lead Autodata Solutions Company David.Morrow(a)Autodata.net <mailto:David.Morrow@Autodata.net> http://www.autodatasolutions.com <http://www.autodatasolutions.com/> Tel: (519) 963-3020 Fax: (519) 451-6615 Think slowly.

[Dovecot] sendfile on Solaris 10 SPARC?

Hi, I am using dovecot-1.0.2 and am observing occassions where the imap process for the user goes into an infinite loop. A truss of the process gives: pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000) = 1 fstat64(10, 0x000BC130) = 0 sendfilev64(1, 1, 0xFFBFF4B0, 1, 0xFFBFF4A4) Err#11 EAGAIN pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000) = 1 fstat64(10, 0x000BC130) = 0 sendfilev64(1, 1, 0xFFBFF4B0, 1, 0xFFBFF4A4) Err#11 EAGAIN pollsys(0x000B0308, 4, 0xFFBFF898, 0x00000000) = 1 fstat64(10, 0x000BC130) = 0 (... repeatedly ...)

Re: [Dovecot] Dovecot strong or not for a big Webmail architecture

Yep... and we have 500K very active users on it. We've scaled Dovecot horizontally without NFS, just lots of independent Dovecot server intances with smart proxy/mail-routing infrastructure around it. It can easily scale to millions of users this way. Just make sure you throw enough disks at it and you'll be fine, with or without NFS. > Do you think it's a good solution to use one synchronised local Openldap on each > server Dovecot ? No. I'd replicate your ldap database on a few servers that are dedicated to that purpose, and on each mail server use Dovecot's auth_cach feature to minimize how often it needs to query ldap. > Do you think It's possible to use Postgresql or MySQL instead of Openldap ? We use MySQL. MySQL handles frequent writes better than OpenLDAP from our experience. It is also simpler for us to do replication and troubleshooting because we employ several MysQL gurus already. > Are cyrus or courrier-imap better solutions ? Definitely not courier-imap, because of it's lack of indexes. Not sure about Cyrus. > Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy > in this architecture, is Dovecot scalable ? My opinion is Zimbra is too heavy beccause of the way mail is stored on the backend. Dovecot with maildir scales out well, and the promise of dbox mail storage format appears that it will make it even more scalable down the road. Bill

[Dovecot] MD5 mis-match
by Big Pizzle 03 Aug '07

03 Aug '07

Hi all, I'm almost finished building our new load balanced email server that are attached to an NFS mountpoint. There are currently two e-mail servers connected to the NFS share. Both email servers are running CentOS 4.5 with Postfix 2.4.3, Dovecot 0.99, and authenticating via LDAP. Dovecot is using Maildir format. I've been trying to do some benchmarks using Postal and Rabid, and whenever I run rabid, I'm getting errors like this: MD5 mis-match, calculated:a628289996ce19910ebbd4eef2ebc3fc, expected 9406a7cf56afb5a1308eb5377e141719! However, when I tail the /var/log/maillog, I don't see errors - I just see the pop3-login. Just wondering if that is okay. I've also been trying to find an RPM for Dovecot 1.0.3, with no avail. Anyone know where I can get one? Thanks in advance. Patrick

[Dovecot] Looking for RPM for 1.0.3 for CentOS with imap, ldap, and ssl
by Big Pizzle 03 Aug '07

03 Aug '07

Hi, I don't know how to compile Dovecot from src rpm;s - in fact I tried and failed miserably. The only other src rpm I have ever built was postfix, and I ran into a whole bunch of errors trying to build an rpm from the src rpm at ATRpm. Anywho, I was wondering if one of you wonderful Dovecot members would be willing to create an RPM for CentOS 4.5 that includes ldap and ssl. Or, if someone knows of a URL I can go to and follow a Dovecot-related src rpm build tutorial, that would be of great help too. Heck - I'll even settle for a 1.0.2. Since Dovecot doesn't support 0.99 I want to make sure I have the most recent package. Thanks in advance. Patrick

[Dovecot] Dovecot strong or not for a big Webmail architecture
by John fistack 03 Aug '07

03 Aug '07

Hello, Do you think Dovecot could handle millions of active users in a big architecture ? This cluster could be for example (each server is a bi quad Xeon 2.66 Ghz) : - 40 Dovecot servers - 4 LVS - 20 Apache+PHP - 2 Openldap - 20 Postfix + ClamAV + SpamAssassin - 1 NFS Netapps For millions of user it could be multiple different clusters of 40 Dovecot servers with 1 Netapp for each cluster. I want to work in NFS. I've experimented problem with Cyrus and NFS on Netapp. I want to use maildir, I can manage limitations of inodes with Netapp. I know webmail.us use Dovecot, what is the most big dovecot architecture known ? Do you think Dovecot can handle 1 million of active users in a good architecture ? Do you think it's a good solution to use one synchronised local Openldap on each server Dovecot ? Do you think It's possible to use Postgresql or MySQL instead of Openldap ? Are cyrus or courrier-imap better solutions ? Someone say "Zimbra is highly scalable and fast", I think Zimbra could be to heavy in this architecture, is Dovecot scalable ? Thank you for your ideas. Regards.

[Dovecot] dovecot 1.0.2, sieve 1.0.2 and regex
by Alexander Hoogerhuis 03 Aug '07

I've just ported a largeish procmail script across to sieve and want to get to use wildcards in filing mail and can't seem to get regex to work. The script starts nicely with: > require ["fileinto","regex","envelope","vacation","regex"]; and a bit down these few lines comes into play: > elsif header :regex "From" "logwatch.*stuff.com" { > fileinto "INBOX.Admin/Logwatch Stuff"; > } and regex just never seem to catch. I have 50ish machines in the stuff.com domain, and writing an induvidual section like this works: > elsif header :contains "From" "logwatch(a)a.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } > elsif header :contains "From" "logwatch(a)b.stuff.com" { > fileinto "INBOX.Adin/Logwatch Stuff"; > } etc. But this shouldn't be neccesary? mvh, A

02 Aug '07

http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz.sig - deliver: v1.0.2's bounce fix caused message to be always saved to INBOX even if Sieve script had discard, reject or redirect commands. - LDAP: auth_bind=yes and empty auth_bind_userdn leaked memory - ACL plugin: If user was given i (insert) right for a mailbox, but not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND commands weren't supposed to allow saving those flags. This is technically a security fix, but it's unlikely this caused problems for anyone. - ACL plugin: i (insert) right didn't work unless user was also given l (lookup) right. - Solaris: Fixed filesystem quota for autofs mounts.

[Dovecot] mbox inbox default
by bhayden＠umn.edu 01 Aug '07

01 Aug '07

HI Timo & all. We're an mbox environment, inboxes in /var/mail/$USER (I'll include dovecot -n output at the bottom of this mail). mail_location is set accordingly for deliver. I'd assumed that if the /var/mail/$USER file doesn't exist, dovecot would create it, but we've discovered from experience (and I verified it in mbox-storage.c) that if access(path, R_OK|W_OK) fails--as it does if the file doesn't exist--that dovecot defaults then to delivering in root_dir/inbox. I'm curious why this is. It seems like if the configured INBOX file doesn't exist, dovecot should create it if possible; it's a different case than if, say, the user doesn't have write access to that directory, in which case it of course would be appropriate to fall back to some other location rather than rejecting mail. Is there something I'm missing that makes my idea wrong?

[Dovecot] High cpu usage OpenSolaris
by Gary Gendel 01 Aug '07

01 Aug '07

All, Nevermind... I discovered the problem. It was in the Solaris Sun Studio 12 compiler. I created a debug version to begin testing, but that version worked without sucking up the cpu. So it looks like the optimizer messed up. If I used the -fast optimization, it sucks up cpu, but with -xO5 all is well. Gary --------------------------------------------------------------------- Hi, I've built 64-bit dovecot 1.0.2 on Opensolaris to replace version 1.0.0rc10. It functions fine, but when I connect, it eats up all available cpu. My guess is that the poll thread is running continuously. Any ideas on what I should do to verify this or does anyone know of a fix? Thanks, Gary

[Dovecot] Missing MIME-Version header in e-mails.
by Tan Shao Yi 01 Aug '07

01 Aug '07

Hi, I notice that in src/lib-mail/message-parser.c, there is a section of code that checks for the presence of MIME-Version before allowing processing of the Content-* headers. Is there a possibility of relaxing this rule? There are some broken mailers, in particular newsletter mailers that do not seem to honour the MIME-Version header, though they do send the Content-Type.

[Dovecot] Mount options and NFS: just checking...
by Mike Brudenell 01 Aug '07

01 Aug '07

Greetings - I'm now in the last couple of weeks before going live with Dovecot (v1.0.3) on our revamped IMAP service. I'd like to double-check about the best mount options to use; could someone advise, please? I have three separate directory trees for the message store, the control files and the index files. These are arranged as follows: Message Store Mounted over NFS from a NetApp filer; filestore quotas are ENABLED. Control Files Mounted over NFS from the NetApp filer; filestore quotas are DISABLED. Index Files Mounted on local disk; filestore quotas are DISABLED. We will have a pair of Solaris 10 servers on which Dovecot 1.0.3 is running. Users are normally directed to their "preferred" server but, if it is unavailable, will go via the other server. Q1. Am I right in thinking that for the Message Store and Control Files I should NFS-mount both of them with the "actimeo=0"? (Or would "noac" be better, which also turns off client write- caching as well as the attribute cache?) Q2. Should I NFS-mount either or both of the Message Store and Control Files with the "noxattr" option to turn off extended attributes? Q3. Which of the filestores should I mount with the "noatime" option? (I understand that for the filer-based NFS mounts this can be done on the filer, as the option isn't available with "mount" for NFS-monted filestores.) Q4. Any other options to use/miss out? Currently my understanding from the list and the NFS page at the Wiki is: A1. Use "actimeo=0" for both Message Store and Control Files. No idea about the need for/impact of using "noac". A2. No idea. A3. Safe to use "noatime" for all three filestores. (I understand Dovecot will use utime() when needed on such filestores, but am not sure if it will work on the NFS-mounted filestores from the filer if access times are turned off at the filer end.) Any thoughts, please?

[Dovecot] mbox bug in 1.0.0
by bhayden＠umn.edu 01 Aug '07

01 Aug '07

Hi folks. We're moving users from rc24 and 27 to 1.0.0. On four mailboxes so far we've seen these errors after the move (quick and dirty anonymizing follows): Apr 23 13:22:41 server.umn.edu dovecot: [ID 107833 local6.info] imap-login: Login: user=<USER>, pid=<9046>, method=PLAIN, rip=***.***.***.***, lip=***.***.***.***, TLS Apr 23 13:22:41 server.umn.edu dovecot: [ID 107833 local6.error] [9073] IMAP(USER): mbox /var/mail/user: seq=1 uid=8808 uid_broken=0 originally needed 10 bytes, now needs 23 bytes Apr 23 13:22:41 server.umn.edu dovecot: [ID 107833 local6.error] [9073] IMAP(USER): Raw backtrace: 0x7b800 -> 0x43434 -> 0x3e018 -> 0x3fc34 -> 0x40080 -> 0x6d3cc -> 0x29a88 -> 0x21324 -> 0x214c0 -> 0x22f48 -> 0x22ec0 -> 0x230c0 -> 0x81c18 -> 0x814e4 -> 0x2b5cc -> 0x1dc58 Points of interest: 1. I can't reproduce this. It still happens after the user's .imap directories are removed. If I make a copy of the mailbox on another machine running the same version of Dovecot with the same config, the problem doesn't occur. Weird. 2. So far, have only seen it on quite large mailboxes (close to or over 100MB). Most large boxes have not had the problem, but the ones that have are all large. Any thoughts?

[Dovecot] dovecot-uidlist locking
by Tony Tsang 01 Aug '07

01 Aug '07

Hi all, I've a dovecot server setup and occassionally clients cannot get mails from their inbox. When I inspect the maildir for that user, there is stale dovecot-uidlist.lock file, and imap process keeps waiting for release of the lock. Is there any other method to perform locking on dovecot-uidlist instead of using dotlock mechanism? It is creating maintenance problems if I need to remove those stale lock files everytime clients hit this problem Tony.

[Dovecot] user name before and after authentication
by François Wautier 01 Aug '07

01 Aug '07

Hi, I am new to dovecot and spend the last few hours trying to configure it to my liking. I am using version 1.0.2 I have a setup where I only have "virtual" mailboxes in various domain ( mydomain.com, mydomain.biz,...). I setup Exim to deliver the email into <some path>/domains/<domainname>/<user> Now I am trying to get dovecot to access those mailboxes I setup LDAP bind authentication against an AD server. it works fine... but I have a problem getting the correct path to the mailboxes. The user logs in as user(a)domain.ext The mailbox path being at <some path>/domains/%n/%u The LDAP module gets the DN for my user and verify that it can binds, and in the process changes the "user" to cn=<real name>,cn=Users,dc=domain,dc=ext There goes my path To make matter worse, the uid and gid are the same for all users and are fixed (exim user and group). Hence cannot be retrieved from AD I tried to use userdb static, but I can't seem to be able to reset "user" to its pre-authentication value userdb prefetch/ldap but I can't set the uid/gid So here are my request for help... Is there a way to set home dir/ mail dir before authentication? Is there a way to reference the pre-auth user name? Is there a way to create arbitrary variables and used them? Is there a way to fix the uid/gid to use to access the mailboxes? Any one of these could probably solve my problem. Any suggestion is most welcome. François

[Dovecot] IMAPs and POP3s poxying
by Jason Russler 01 Aug '07

01 Aug '07

Hi All, I have a polotical situation at work that requires that I off-load mail access to a host other than the one our users have configured in their clients. I don't have access to any of the switching or routing to our hosts, and there's only a 1 to 1 relationship between the proxy I want to set up and the actual mail handler. I was looking at the proxying Howto in the Wiki and was presented with an SQL server requirement to do user/ip address look-ups. In my case, it will always be proxying the same host. How would I configure Dovecot to proxy another single system without doing the SQL look-up? Is there a port-forwarding solution that would work better (for POP3s and IMAPS)? These are RedHat 5 hosts so Netfilter is fair game if the protocols allow. Thanks, -Jason

[Dovecot] apparent bug with filesystem quota and message lists
by Stewart Dean 01 Aug '07

01 Aug '07

Don't know if anyone else uses Berkeley derived filesystem quota, but IBM's AIX does. A little over a week after migrating from UWIMAP to DC (with mbox format unchanged) everything is clean except for this one problem: When users go over quota, when they login the next time, the folder list is blank. You can imagine the panicked calls to the Helpdesk. If their quotas are raised or re-graced, Get Mail returns the expected list. This behavior happens with a variety of clients: Pine, MacMail,TBird, Horde Webmail, etc. The index filesystem has no quota on it. I would have to imagine the Dovecot is using (or trying to use) some space in the quota'ed filesystems which the operating system won't allow, and this results in there being an empty file that DC uses for the message list sent to the client. There are NO messages in syslog (other than the expected login and logout) indicating any problems. Our legacy setup has the inboxes in /var/spool/mail, and the folders in ~/mail. The problem can happen either place. dovecot -n returns: > # 1.0.1: /usr/local/etc/dovecot.conf > listen: *:143 > ssl_listen: *:993 > disable_plaintext_auth: no > login_dir: /var/run/dovecot/login > login_executable: /usr/local/libexec/dovecot/imap-login > login_processes_count: 12 > login_max_processes_count: 774 > verbose_proctitle: yes > first_valid_uid: 200 > mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u > mbox_dirty_syncs: no > mbox_lazy_writes: no > auth default: > passdb: > driver: pam > userdb: > driver: passwd Suggestions? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot won't build against recent version of GnuTLS
by Jasper Bryant-Greene 01 Aug '07

01 Aug '07

Hi all, Dovecot won't build against recent versions of GnuTLS. The problem starts on line 34 of src/master/ssl-init-gnutls.c, where Dovecot generates DH params using gnutls_dh_params_generate(), a function which no longer exists [replaced with gnutls_dh_params_generate2()]. I'd fix it myself, but the signature of the function has changed to take gnutls_dh_params_t rather than prime & generator, and I'm not keen on hacking SSL code unless I really understand what's going on. It looks like the code goes on to save & free those values. I'm tracking HG and am happy to test any changes. Appreciate it if someone with more knowledge of GnuTLS and perhaps this code in particular could take a look. Thanks, J

[Dovecot] pop3 connections hanging
by Arjun Datta 01 Aug '07

Hi, dovecot --version 1.0.beta8 dovecot -n login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd It is running with sendmail-8.13.5-3 on FC5 2.6.15-1.2054_FC5 I find that occasionally a pop3 connection will just sit there for hours on end. It will not release the lock on the user mailbox and so mail to that user cannot be delivered. As a result the mailq backs up mostly with mail to that user. Closing the MUA does not help. I have to kill -9 PID the process to clear the hung connection. This happens with both Outlook and Thunderbird. Is there an option in the dovecot configuration that I can set to automatically close connections after say 30 minutes ? In the workaround section it says that it will close connections from Outlook & Outlook Express after 30 minutes dues to an IDLE bug in those 2. Regards, Arjun Datta

[Dovecot] Dovecot LDAP schema?
by Hadmut Danisch 30 Jul '07

30 Jul '07

Hi, does dovecot define its own LDAP schema or should I create my own one? (I want to provide IMAP boxes for virtual users that do not have a Unix account on the mail server and thus do not want to use the plain uid/gid entries of the posix account objectclass to avoid confusion and accidently giving access to accounts.) regards Hadmut

[Dovecot] High cpu usage OpenSolaris

Hi, I've built 64-bit dovecot 1.0.2 on Opensolaris to replace version 1.0.0rc10. It functions fine, but when I connect, it eats up all available cpu. My guess is that the poll thread is running continuously. Any ideas on what I should do to verify this or does anyone know of a fix? Thanks, Gary

[Dovecot] Shared mailboxes (maildir, symlinks) and permissions
by Andreas Ntaflos 28 Jul '07

28 Jul '07

Hello list, I am trying to set up a public mailbox for users to put spam in so that sa-learn can do its job at night. Only I can't seem to fully understand how and which permissions should be set. I've read [1] and am using Dovecot 1.0.1. First some background information: I do not host or care (at the moment) about virtual users or virtual mail hosting. All users have Unix system accounts and shell access. I'd like to have a Spam folder, say /var/mail/public/.Spam that is a maildir where users can put Spam that got through the server-side filter. Spamassassin's sa-learn runs nightly and learns from the contents of the Spam folder. After reading [1] I think I should have under /var/mail/public a file called dovecot-shared that belongs to root:mail and has permissions 0660 (with user dovecot being a member of group mail) so that it looks like this: root@host:/var/mail/public# ls drwxr-sr-x 2 root mail 4096 2007-07-28 03:29 . drwxrwsr-x 3 root mail 4096 2007-07-28 02:19 .. -rw-rw---- 1 root mail 0 2007-07-28 02:46 dovecot-shared root@host:/var/mail/public# The first question arises: should Dovecot have write access to /var/mail/public itself? Now I should create the Spam folder called /var/mail/public/.Spam. Should this directory be in maildir format, i.e. should it already contain the subdirectories cur, tmp and new? What of the permissions of this directory? I am pretty sure Dovecot needs write access to it, so it should look like this: root@host:/var/mail/public# ls drwxr-sr-x 3 root mail 4096 2007-07-28 03:44 . drwxrwsr-x 3 root mail 4096 2007-07-28 02:19 .. -rw-rw---- 1 root mail 0 2007-07-28 02:46 dovecot-shared drwxrwsr-x 2 root mail 4096 2007-07-28 03:44 .Spam root@host:/var/mail/public# The .Spam directory here is completely empty. Now in a user's Maildir (/home/user1/Maildir) there are the user's private folders; a symlink to /var/mail/public/.Spam should be added: root@host:/home/user1/Maildir# ln -s /var/mail/public/.Spam . root@host:/home/user1/Maildir# ls ... drwx------ 5 user1 user1 4096 2007-07-19 16:14 .INBOX.foo drwx------ 5 user1 user1 4096 2007-07-06 23:01 .INBOX.bar ... lrwxrwxrwx 1 user1 user1 22 2007-07-28 03:51 .Spam -> /var/mail/public/.Spam ... root@host:/home/user1/Maildir# Is that all I have to do? Probably not, because I keep getting errors like the following when connecting (after subscribing of course): Jul 28 03:52:35 host dovecot: IMAP(user1): mkdir(/home/user1/Maildir/.Spam/cur) failed: Permission denied Should I have created the cur, tmp and new subdirectories manually and set their permissions like /var/mail/public/.Spam? But that still wouldn't give user1 write access. If I gave the users (or "others": chmod o+w) write permissions then Dovecot's index files would be owned by the first user that connects to the server and uses that folder. Apparently also not a solution. I also don't think I should have to make my users members of the mail group, but I could be wrong here. So I am not sure what I am missing, or if what I want to do is at all possible (without taking out the sledgehammer and setting all permissions to 0777). I also apologise for this lengthy post with many details and little interesting questions. It's getting late and I fear I've reached a dead end. I'd really appreciate it if someone knowledgeable could point me in the right direction here. Thanks in advance!

[Dovecot] auth_cache_...
by Frank Elsner 26 Jul '07

26 Jul '07

Hello, the dovecot-example.conf states: # Authentication cache size in kilobytes. 0 means it's disabled. # Note that bsdauth, PAM and vpopmail require cache_key to be set for caching # to be used. #auth_cache_size = 0 # Time to live in seconds for cached data.

For now this works only with plaintext authentication. #auth_cache_ttl = 3600 auth_cache_size = 0, does it mean "cache can grow ad infinitum" or does it mean "no cache at all" ?

[Dovecot] Vacation message functionality
by Charles Marcus 25 Jul '07

25 Jul '07

Hi, Since I will soon be attempting to get this working on one of my client's systems, I posed a question on the postfix list - since they mostly dislike vacation messages - but *ardent haters* of badly configured vacation message systems - as to the quality of the dovecot vacation message function. The only response I got did seem to have a few very good suggestions for additional conditions to test for, so I'm posting the response here to see if they can be incorporated (I'm not a coder or I'd attempt it myself). The original text (prefixed by double quote characters) in the following exchange is what I copied/pasted from the wiki, and the reply (prefixed by one quote character) is the suggested change/enhancement (this reply is from a trusted source on the postfix list): >> Vacation auto-reply >> >> The vacation replies are sent to the envelope sender. Currently this >> is taken from the Return-Path: header in the message. > comment: > or from the command line if this is supported. > > also, if the envelope sender is not available, no reply should be > sent. >> List of autoreplied senders is stored in .dovecot.lda-dupes file in >> user's home directory. When you're testing the vacation feature, it's >> easy to forget that the reply is sent only once in the number of >> configured days.

[Dovecot] Thunderbird body search and multiple imap process
by Oliver Schulze L. 25 Jul '07

25 Jul '07

Hi, I'm having an issue with dovecot and Thunderbird and it is reproducible all the time. You do many body search from TB and you end up with multiple imap processess consuming all the CPU and with linux load 20+ Setup: - Centos 4.5 - Thunderbird 2.0.0.5 - Dovecot 1.0-7_53.rc29 and 1.0.1-1_58.el4 How to reproduce: - have an imap account in Thunderbird with 12000+ emails - user maildir in dovecot - do a: ps auwx|grep user1|grep imap|wc -l - in the main window of TB, in the sarch box select "Entire Message" - search one random word and wait 30 seconds - search another random word and wait 30 seconds - search another random word and wait 30 seconds - search another random word and wait 30 seconds - do another: ps auwx|grep user1|grep imap|wc -l - watch that the user1 have now more imap process - watch the linux load, it just rocketed from 1 to 20 - killall -9 imap - watch the linux load return to 1 I'm thinking its TB fault, anyone has seen this issue too? Thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion - Paraguay | http://www.solojuegos.mobi

I'm just curious to know > what your motivation is. Why is it evil? Why do you hate it? EXPUNGE command is specified to expunge the mails, not move them to another mailbox. This would make having the message really gone a 4 stage operation: Mark deleted, expunge, mark deleted in Trash, expunge Trash. In many clients when you mark a message deleted it also copies it to Trash. So a server side expunge-to-trash feature causes the message to get copied there twice. A Trash mailbox also has the problem that all of your messages get there. There's no way to have an easy "unexpunge" operation, because the original mailbox isn't saved anywhere. You have to manually copy the message to the wanted mailbox. Perhaps lazy-expunge is a bit similar, but it preserves the mailboxes and doesn't conflict with clients' move-to-Trash feature. Also the concept in general is about having easily restorable backups of mails and not some kind of a idea that mails should go to a Trash mailbox when they're deleted. Maybe that whole Trash concept is the reason I consider it evil. I don't like that Trash concept in desktop environments either. I wish the undelete feature was in filesystems, so that when disk is full, the oldest deleted files would automatically get overwritten with new data, but until then the files would be undeletable. >> I think having a virtual Trash mailbox that contained all messages >> marked >> as deleted in all mailboxes would be a good solution for this. > > That's not quite the same thing.

[Dovecot] Quota plugin, Maildir, dict backend loop problem
by David Jonas 25 Jul '07

25 Jul '07

Hello, I've been working with the quota plugin(s) the past few days and have been having some real trouble. Only a few entries are appearing in the database, a couple more when I restarted dovecot. None of the current entries were being updated either. I think I've tracked it down to somewhere in the dict backend. I put in a few i_info() statements and recompiled. A few queries get through, then it seems to try the same query about three times and then no new more queries at all (the i_info is right after the allocation of the query string). I couldn't find any errors in the log. An strace of the dict pid shows the following loop. Dovecot -n to follow as well. A quick tcpdump showed a loop something like this: < SELECT current FROM quota WHERE ... > 513965019 < BEGIN < INSERT INTO quota (current, ... < COMMIT > ?? (error_r appears to be (null)) .. repeat .. In all my tests it appears that the quota value being set during the loop is 0, but that would be the most common case anyway. An insert query would look like this: INSERT INTO quota (current, path, username) VALUES (0, 'quota/storage', 'user(a)example.com') ON DUPLICATE KEY UPDATE current = current + 0; Help on what to do/try next would greatly be appreciated.

Hello, I have read in lots of places about how I should use pop3_reuse_xuidl = yes to prevent pop3 users having to re-download mail (and duplicate their e-mail) after a migration. This fails with the message: pop3_uidl_format setting is missing from config file Which setting for pop3_uidl_format should I set to prevent the e-mail being downloaded again?

[Dovecot] v1.1 alpha1: can't pop/imap login with LDAP
by Katsu Yamamoto 25 Jul '07

25 Jul '07

Hi, We recentlty upgraded our dovecot from v1.0.2 to v1.1ahpha1 under CentOS 4.4. Also, we are using Postfix 2.4.3 and OpenLDAP 2.3.35. We've been using LDAP for our POP/IAMP user authentication, however after upgrading to v1.1alpha1, LDAP authentication does't seem to be working properly. We re-examined the source code, and made a few modification. We are suspecting that... (1) db-ldap.c is not handling value properly?? (2) userdb-ldap.c is not allocating memory for userdb_reply?? The modification we made are following: *** src/auth/db-ldap.c.orig Thu Jul 12 10:42:49 2007 --- src/auth/db-ldap.c Tue Jul 24 20:20:31 2007 *************** *** 55,60 **** --- 55,62 ---- BerElement *ber; string_t *var, *debug; + + int value_index; }; #define DEF_STR(name) DEF_STRUCT_STR(name, ldap_settings) *************** *** 764,769 **** --- 766,772 ---- ctx->vals = ldap_get_values(ctx->conn->ld, ctx->entry, ctx->attr); ctx->value = ctx->vals[0]; + ctx->value_index = 0; } static void *************** *** 797,804 **** db_ldap_result_change_attr(ctx); } else { /* continuing existing attribute */ ! if (ctx->value != NULL) ! ctx->value++; } if (ctx->value != NULL) { --- 800,806 ---- db_ldap_result_change_attr(ctx); } else { /* continuing existing attribute */ ! ctx->value = ctx->vals[++ctx->value_index]; } if (ctx->value != NULL) { *** src/auth/userdb-ldap.c.orig Thu Jul 12 10:42:49 2007 --- src/auth/userdb-ldap.c Tue Jul 24 20:33:45 2007 *************** *** 37,42 **** --- 37,44 ---- struct db_ldap_result_iterate_context *ldap_iter; const char *name, *const *values; + auth_request_init_userdb_reply(auth_request); + ldap_iter = db_ldap_result_iterate_init(conn, entry, auth_request, conn->user_attr_map); while (db_ldap_result_iterate_next_all(ldap_iter, &name, &values)) { With the modification, LDAP authentication is working without any problem, at least for our system. However we are not sure whether the above modification affect other functions of dovecot. Is there an official patch to fix the problem already released? And somehow we missed it? If there is no patch, then will there be any to be released sometime in near future?
