If so, I think the behavior is correct. Maybe change the query to: where username = '%n' and (domain = '%d' or ('%d' = '' and domain is null)) And change all the domain='' to domain=NULL.

[Dovecot] New to list, got a quota question
by Vlad Sedov 13 Mar '09

13 Mar '09

Hello folks - I'm running dovecot on top of qmail/vpopmail/mysql, serving up about 2500 mailboxes. Everything is running very smooth and fast.... I recently upgraded dovecot to 1.1, so I'm trying to implement some extra features like IMAP quotas. I'm using the sql passdb, with the following config: driver = mysql connect = host=/var/lib/mysql/mysql.sock user=username password=password dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 508 AS uid, 503 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' My vpopmail installation keeps the quota information in the mysql database (pw_shell field) instead of maildirsize. The quota is in maildir format, e.g. 400M or 50331648S. Unlimited quota is specified as NOQUOTA. The question is... Is it possible to make dovecot understand this format and get it directly from SQL (via user_query, for example) or would it be easier to reconfigure the vpopmail installation somehow to use maildirsize? Thanks! Vlad

[Dovecot] how to handle CA CRL updates with client certificate verification context ?
by Raphael PRECIGOUT 13 Mar '09

13 Mar '09

Hello, As far as I can read in the Dovecot SSL configuration wiki page, each CA cert must be followed by the related CA CRL in the client certificate verification context ("ssl_ca_file" setting). In my company we do have our own PKI and as soon as Client certificate is compromised we do revoke it and update the related CA's CRL. Does that mean that I have to issue a new "ssl_ca_file" file as soon as our issuing CA CRL is updated ? If yes, does someone has an idea on how to do so ? Is it then necessary to restart dovecot process (to take the "ssl_ca_file" file changes into account) ? Does Dovecot have a way to check the issuing CA CRL automatically ? (the CRL is published in DER format and is accessible though http, the URI is mentionned in the CRL Distribution points of the CA certificate) Thanks in advance for your help. Regards, Raphael

[Dovecot] Problem with sasl auth with postfix...
by Douglas M. Stanley 13 Mar '09

13 Mar '09

Hello list, I'm running into some problems, and I couldn't find any info about this anywhere on the net. I recently set up a new debian lenny machine, and used my notes from the last debian etch machine I set up, which basically is for postfix + dovecot for sasl auth. On my old etch box, in the dovecot.conf, in the auth default section, I have a socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } However, if I use the same config on my lenny setup, dovecot fails to start, and I see this in my logs: Mar 13 19:16:30 mailserver dovecot: Dovecot v1.0.15 starting up Mar 13 19:16:30 mailserver dovecot: auth(default): User doesn't exist: postfix Mar 13 19:16:30 mailserver dovecot: Auth process died too early - shutting down Mar 13 19:16:30 mailserver dovecot: child 4623 (auth) returned error 89 Now if I comment out the user and group lines, it works fine, but the socket is owned by root, and so I have to change the mode line so that it's world readable in order for postfix to use it. The version of dovecot in etch is: 1.0.rc15-2etch4 and the version in lenny is: 1.0.15-2.3 Any ideas why this might be happening? Did the syntax to do this change between those versions? Any input? I guess I don't mind leaving it world readable, but I wasted an entire morning trying everything to get it to work, so I guess I'm hoping some one atleast has an answer as to why it doesn't work. Thanks, Doug

[Dovecot] Using LDAP for Dovecot extra/regular fields
by Jack Stewart 13 Mar '09

13 Mar '09

Hi, We're moving to a dovecot proxy / server configuration in order to make sure that a users go to a specific server. If someone has used these LDAP for this, there are a few things that I wish to verify. Dovecot does not verify that type of the LDAP attribute, only that the returned value works. If a boolean is used for a yes/no field, then FALSE sets the field to no and TRUE sets the field to yes. If a multivalue attribute is used for a single value field, the last returned value for the LDAP lookup is used in that field (i.e. host will use the last value). If a string attribute is returned for a yes/no field and has any value, then the associated field is set to true. There is no automatic failover with the host field so if the remote host is down, the IMAP connection no longer works. I'm fairly sure of all of these except for the boolean. Now this is just due diligence. I don't know that turning on/off or switching LDAP attributes is the right way to go to handle failover but it might work for phased rollout. My feeling is the best configuration will be using a secondary IP address that has to be manually turned on for a host after a reboot or shutdown. This creates a poor mans "fencing". The secondary can either be brought up on another host or handled via a load balance with DSR/backup server. As a practical matter, it is probably worth setting sensible attributes for each field (i.e. numeric for host, boolean for proxy/proxy_maybe etc). Any interest in registering an LDAP object class for dovecot? ---Jack

[Dovecot] Maildir dirty syncs
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/patches/1.1/maildir-dirty-syncs.diff This patch adds a new maildir_very_dirty_syncs setting. If set to "yes", Dovecot assumes it's the only one changing the cur/ directory (so other MDAs can add mails to new/ without problems). This makes it possible to avoid rescanning the cur/ directory all the time looking for filenames. It also looks like (in stress testing) it still scans the cur/ directory unneededly in some situations, but it shouldn't be common. Maybe I'll look into it some day to see why. I'd be interested in hearing how large performance benefits it gives, if any. If they're big I could consider adding it to v1.1.12. If they're pretty much irrelevant I probably won't even bother adding the code to v1.2. I guess you mainly see the performance benefits with large/huge mailboxes.

[Dovecot] General approach question - am I doing this the right way?
by Alan Bates 13 Mar '09

13 Mar '09

Quick outline of my current working setup: I'm running dovecot 1.0.5 as an IMAP mail server on my ubuntu home server, which i connect to with my phone and several other machines to check my mail etc. i use getmail to collect mail from my various pop accounts. getmail filters the mail using spamassassin via a Filter_external, before moving it to my Maildir on the home server. Then when I connect to the home server from my various machines, IMAP manages the status of all the mail, so unread messages are common etc. All works very nicely. However I'd like to fix a minor annoyance... ...Spamassassin marks mail as SPAM but the mail client has to do the job of moving it to the Junk folder. I'd like the mail to be filtered on the home server on receipt. Am I just making things really complicated for myself? Is there a simpler setup for what I'm trying to do? Thanks in advance for any thoughts or suggestions

[Dovecot] Extremely custom mailbox locations
by Steve Kemp 13 Mar '09

13 Mar '09

I'm in the position where I'd like to offer IMAP access to a collection of email accounts which are stored in a very odd manner. Files are stored as: /blah/$dd-$mm-$yy/$domain/1234/1234 For example: /reject/12-3-2009/cvsrepository.org/35199/35199639 There is a single file for each mail, which I guess technically probably counts as an mbox folder, but only just. I can handle the custom login requirements I have, but I see no obvious way to create a mailstore from this information unless I build up a parallel symlink farm, such as: /imap/cvsrepository.org/{new cur tmp} I suspect if I fill cur/ with symlinks to each of the individual messages things will mostly work out OK, but I wonder if that is the best solution, or if there is a slim chance that I could serve this hierarchy without the intermediate step?

[Dovecot] which architecture to use?
by GVG GVG 13 Mar '09

13 Mar '09

Dear List, Based on the following installed environment: - OpenBSD (latest version!) - PostgreSQL - dovecot with SSL would like to have a mail server which accepts system as well as virtual users and being able to connect to their mailboxes either via an MUA (Thunderbird etc.) or a web interface (squirrel mail?). When using the web interface, non registered users should be able to creat e-mail accounts which will be dovecot virtual users! Which components should I use? Thanks

[Dovecot] 1.1.12 release candidate
by Timo Sirainen 12 Mar '09

12 Mar '09

http://dovecot.org/tmp/dovecot-1.1.12.rc.tar.gz I would have already released 1.1.12, but it needed the MAILBOXDIR change described below, and I'm slightly worried that it might have broken some special setup. So please test first and I'll release in v1.1.12 then in a few days. * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] Imap logout message on Dovecot restart
by RutgerM 12 Mar '09

12 Mar '09

I'm trying to receive a "Disconnected" message in my logfile for the connected imap-clients when I restart dovecot. When you disconnect a client, you receive the following message in your log: Mar 12 21:45:55 mail dovecot: IMAP(mailbox(a)domain.com): Disconnected: Logged out bytes=7496/22441 When a IMAP client is connected and Dovecot is restarted, this message is not shown. This should be solvable by a script like this: #!/bin/sh unset LOG_TO_MASTER export USE_SYSLOG=1 exec /usr/lib/dovecot/imap But this logs the user that runs the script into the imap server and when I terminate this terminal I get a "Disconnected" message for the local linux user, which I don't need of course. Is there a way to get to what I want ? I want to log my IMAP statics for every day and I need to "disconnect" my imap clients for it in some way to receive the Disconnected message and count from there. Thanks.

[Dovecot] High load/corrupted indexes after moving mailboxes?
by Patrick A. Treptau 12 Mar '09

12 Mar '09

Hello, we're experiencing an odd issue after combining two vDisks used for mail storage into one big new LVM. We've done this in the past successfully and didn't experience a lot of problems. We stopped all services (dovecot/postfix) to ensure that mailbox contents (Maildir) will not be changed, rsynch'ed the mail to the new disks and restarted everything. When we restarted dovecot, we noticed a huge spike in load (average load in top and high cpu iowait) and isolated dovecot as the issue. At some point, the average load crept up to over 100 and crashed the server twice. However, over time the average load and cpu wait times went down slightly. I have noticed a spike in load after moving user's mail storage, but not like this. It almost looks like everyone is either re-indexing or re-caching their mail? Any help would be appreciated. We're on dovecot 0.99. -Pat

[Dovecot] migration from dovecot to dovecot on different servers without downtime (dovecot replication?)
by Pau Oliva 12 Mar '09

12 Mar '09

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due to the huge Maildirs (some users have more than 10 years of mail) this tends to be quite slow and painful. Can I tar all the user's Maildir and move them from one box to the other, and then run imapsync again? which I assume that would be faster... or is there any better solution I am not aware of? (ie: I've seen some emails about dovecot replication on the list archives, but few details of how that should be configured). I'd appreciate any feedback or thoughts on this matter. Thank you. Cheers, Pau Oliva

Ok - at this time I am using the following non-default settings: Samba server - smb.conf [Mailstorage] ea support = Yes use sendfile = Yes fake oplocks = Yes delete readonly = Yes Dovecot - dovecot.conf mmap_disable = yes dotlock_use_excl = yes fsync_disable = yes lock_method = dotlock I'm still testing - but at this time I'm seeing no errors. Two options I can state cause severe problems are the "directio" and "setuids" mount options for the cifs client. -- Daniel

[Dovecot] [Fwd: Re: [vchkpw] vpopmail now has vusage daemon support]

Is the index modification code portable that other software could link to a Dovecot library and update indexes on delivery? <snip from vpopmail list> Rick Romero wrote: > I was considering changing vdelivermail to have a stdout option, where > you could pipe from vdelivermail to Dovecot's deliver for 'final' > delivery instead of direct to Maildir within your .qmail-default file. > That 'should' allow everything else to occur normally, but get those > indexes updated as well.

[Dovecot] Error crosscompiling
by Diego Roversi 10 Mar '09

10 Mar '09

Hi, I was trying to crosscompile dovecot, but I got some error: --with-notify=inotify don't work, as it try to run a test program to verify if inotify is supported in the building platform. Solved with --with-notify=dnotify. Ihmo, is more a hack than a solution. | checking whether posix_fallocate() works... configure: error: cannot run test program while cross compiling I can't find an a suitable option for this error. Again the problem is that configure can't run an executable for a different platform. It's possible to set a safe default? Thanks in advance. -- Saluti / Regards Diego Roversi | | diegor at tiscalinet.it

[Dovecot] Random timeouts on mailboxes
by Bastien Semene 10 Mar '09

10 Mar '09

Hello, My dovecot server is currently having random issues when users want to acces their mailbox. When the issue is occuring there's a timeout. It's random because it happens more or less often and is not dependent on a user or the way their check the mailbox. The time during the problem occurs is random, sometimes it's less than a minute, sometimes it's some hours. When a user can't connect to its mailbox, he generally can receive its emails through his BlackBerry (it's just to illustrate the fact that it doesn't seem to be linked to an account). When this issue occurs they can't receive the headers from any folder (INBOX, custom, sent, ...) and can't read mails that headers are known by the mail client. When there's timeout, users can send emails (same jail and with an error when the client want to write a copy in the sentbox) and use the calendar server for example (on the same machine). Dovecot is running on a FreeBSD 7.0 32bits, 4GB RAM, Intel Xeon QuadCore @ 1.86 Ghz, and 3*500Gb SATA-2 RAID-5 disks. The box is hosting jails, and the mail jails ( imap + smtp, clamav + spamassassin ). The mail jails are new (since August 2008) but worked great since the beginning of this year. The server is hosting 122 accounts currently. My first thought was that there's an I/O issue, the disks are maybe too busy or there's paging that result in a timeout. I check it through vmstat an top commands but nothing appears, there's always some memory free (between 90-300 MB) and a very little paging, generally around 1MB. The fault are under a hundred and when, few times, it has more than a hundred (generally under 200) the next snapshot is under 100. I set the screen/line to refresh every 5 seconds. I shutdowned all jails not directly related to the mail service but the problem still occured. I also separated clamav and spamassassin from imap and smtp to a different box. After that I checked the dovecot config to lighten it, and ( only ) disabled fsync. I upgraded the RAM, added memory is used, but nothing changed. The human resources are constantly changing here, we were more before the problem started than now (around 10-15%), to illustrate the fact that I don't think it is linked to the number of users. I tried to recreate some accounts having the issue, but the problem appeared again. I upgraded Dovecot Friday to 1.1.11 from 1.1.7 (The installation was before 1.1.7, I did an upgrade some times ago). I used a command script to log Thunderbird's IMAP activity, everything is fine but there's no timestamp in the logs. So I'm only sure now this is not an erroneous packet/info sent problem. I watched the TB doc ( http://www.mozilla.org/projects/nspr/reference/html/prlog.html#25306 ) but there's no directive to put a timestamp for each line of log. The network is fine. I tried different configuration to be sure a device isn't doing something weird. Now, I don't know what to check to identify the issue. If anyone has any idea I didn't wrote here, or if I did erroneous interpretation(s) from the datas, I'll be glad to know. Regards, -- Bastien Semene Administrateur Réseau & Système

Hello, I'm a software programmer and I work for a software corporation. We worked on dovecot for a while. We want to add some new functions to dovecot. For example, the mail stored on Mail-Server is plaintext, so we want to make it encrypted. As the documentation was not too much, and read the source code was too difficult for em. Would you give me some advice if I make this specialty as a plugin? Thank you! WD David from China.

Re: [Dovecot] Random timeouts on mailboxes
by listacc＠gmx.de 09 Mar '09

09 Mar '09

Hi Bastien, just a little thought because I had an issue like this (but with cyrus): Where is your thunderbird installation stored? In my case, it was not locally but on some windows mapped drive, and so also the imap cache of thunderbird was on this drive. Because we have a lot of mails in our accounts, the cache was about 50-100MB for some users, and users with a lot mail accounts had very often timeouts. This was due to performance problems on our network storage. Sometimes it also works to delete thunderbird´s cache files. Then it has to download all the headers again (bad with bad performing network storage :-/), but it seems that these cache files get corrupted from time to time and this also produces timeouts. kind regards Andreas -- Computer Bild Tarifsieger!

[Dovecot] Using account alias as login
by Javier Amor García 09 Mar '09

Hello, I use dovecot with a LDAP backend for user account and aliases. The aliases are objects of the class couriermailalias. Some users would like to use the alias address as POP/IMAP login instead of the 'true' account. Is this possible?. I am using dovecot version 1.0,10, from ubuntu hardy packages.

[Dovecot] Dovecot and Pipermail integration
by Ricardo Ramirez 09 Mar '09

09 Mar '09

Hello, I have a standard Mailman/Pipermail install with mboxes at MM_HOME/archives/public/listname.mbox/listname.box What's the best way to export these via IMAP using Dovecot 1.0rc15 on Debian etch? I know I could make a namespace with MM_HOME/archives/public/ but that would result in half of the directories being exported (the ones containing the HTML archives) being unusable. I could also create another directory and symlink all the mboxes in there but that seems wrong. Preferably, I'd like to have something like a namespace with a mail location of MM_HOME/archives/public/*.mbox/ but that doesn't work with v1.0 Ricardo

[Dovecot] system & virtual setup
by Jim Pazarena 07 Mar '09

07 Mar '09

No one replied to my original email, and I was hoping if I re-phrase my question I can get an answer. I would like dovecot to provide system email (located at /mail/%u with system password and /home/%u) and also virtual email (/u/mail/VIRTUAL/%d/%u with password found at /u/exim/etc/VIRTUAL/%d/passwd). NO home space, but I would consider /home/%d/%u This I think has something to do with namespace, but the docs are too vague for me to understand. Can anyone help me out? I would very much appreciate it. I would even consider PAYING someone to set me straight. I am looking to migrate away from vm-pop3d. initially with POP3 and ultimately into IMAP. Thanks!

[Dovecot] imap locking spool?
by Mark Hedges 05 Mar '09

05 Mar '09

How does IMAP lock the /var/spool/mail/user file? Here's my problem: I'm writing a script to expire old or oversize mail through a series of archive folders. I don't want to take the whole server down to do this, nor does it seem like I would have to lock the user out entirely if I can manage to emulate the locks correctly. I am able to lock /var/spool/mail/user (and ~user/mail/*) from procmail, dovecot popmail, and openwebmail using dotlocks. What do I do to prevent dovecot imap from writing the spool and various mbox files while my script is running? Just posix fcntl on the various files? I'm trying to use Mail::Box in perl which I'm having some problems with, corresponding with the developer, but if anyone has any easy way out I would appreciate the advice very much! Mark

[Dovecot] failed assertion in 1.1.8: istream.c: line 81
by Alan Ferrency 05 Mar '09

05 Mar '09

Hello, We're having a problem in Dovecot 1.1.8 with a failed assertion on certain mbox format mailboxes. It happens both with deliver when it attempts to delier to the mailbox, and with IMAP connections for the affected box (though I'm not sure what they're doing at the time). Mar 3 12:55:26 <snip> dovecot: Panic: IMAP(<snip>): file istream.c: line 81 (i_stream_read): assertion failed: (_stream->skip != _stream->pos) This is on FreeBSD 6.2, without any nfs. The IMAP client is Squirrel Mail, but as I said, the assertion occurs with deliver as well. Apparently, moving the inbox out of the way fixed the problem for a while, but then it came back. Clearing out the dovecot index files seemed not to have any effect. I have a core dump available for deliver; here's a backtrace: #0 0x282bbecb in kill () from /lib/libc.so.6 #1 0x282bbe68 in raise () from /lib/libc.so.6 #2 0x282bab78 in abort () from /lib/libc.so.6 #3 0x080b7ad8 in default_fatal_finish (type=LOG_TYPE_PANIC, status=0) at failures.c:150 #4 0x080b7dbb in i_syslog_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)", args=0xbfbfe2a4 "{\215\r\bQ") at failures.c:308 #5 0x080b7c37 in i_panic (format=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)") at failures.c:197 #6 0x080bb8a1 in i_stream_read (stream=0x8102e28) at istream.c:93 #7 0x080bbd3d in i_stream_read_data (stream=0x8102e28, data_r=0xbfbfe350, size_r=0xbfbfe354, threshold=0) at istream.c:322 #8 0x0806d85b in istream_raw_mbox_get_body_size (stream=0x8102e28, expected_body_size=11013) at istream-raw-mbox.c:562 #9 0x080736dd in mbox_sync_do (sync_ctx=0xbfbfe640, flags=0) at mbox-sync.c:151 #10 0x08075700 in mbox_sync (mbox=0x8103028, flags=0) at mbox-sync.c:1833 #11 0x08070001 in mbox_save_init (_t=0x80f2980, flags=0, keywords=0x0, received_date=1236108538, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0x0) at mbox-save.c:318 #12 0x282ee17f in quota_save_init (t=0x80f2980, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at quota-storage.c:236 #13 0x0808e36d in mailbox_save_init (t=0x5, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at mail-storage.c:726 #14 0x0808c34a in mail_storage_copy (t=0x80f2980, mail=0xbfbfe9f0, flags=0, keywords=0x0, dest_mail=0x8106028) at mail-copy.c:28 #15 0x282ee08a in quota_copy (t=0x80f2980, mail=0x80fd028, flags=0, keywords=0x0, dest_mail=0x8106028) at quota-storage.c:180 #16 0x080590a4 in deliver_save (namespaces=0x80f7028, storage_r=0xbfbfeb60, mailbox=0x80d0eeb "INBOX", mail=0x80fd028, flags=0, keywords=0x0) at deliver.c:237 #17 0x0805a90c in main (argc=5, argv=0xbfbfec14) at deliver.c:1093 Does anyone have any clues on how to debug this further?

[Dovecot] deliver to root
by Philipp Kolmann 05 Mar '09

Hi, we use dovecot 1.1.11 on a RH Server with sendmail. Local delivery is done with deliver: Mlocal, P=/usr/local/libexec/dovecot/deliver, F=lsDFMAw5:/|@qSPfhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=deliver -d $u This setup works without issues for us, but mail to root has a problem with deliver: deliver(root): Mar 04 16:31:31 Error: userdb(root) returned 0 as uid deliver(root): Mar 04 16:31:31 Error: userdb(root) returned 0 as gid deliver(root): Mar 04 16:31:31 Error: User root is missing UID (set mail_uid) Is it generally not possible to use deliver to deliver mail to root?

[Dovecot] set \Seen flag on mail
by J.P. Trosclair 04 Mar '09

04 Mar '09

I'm looking for a way to set the \Seen flag on certain mail no matter what. Currently I'm using a global sieve script to do this. From what I've read, there is no way to enforce the global script if the user creates their own sieve script. More details: I have a postfix transport that along with sender_bcc_maps and recipient_bcc_maps uses deliver to create a read only archive of user's mail. The mail intended to be archived is stored in a per user imap folder called "Archives" that uses the ACL plugin to make the messages there read only. In addition to that, I want the mail marked as \Seen upon delivery so that user's who subscribe to the Arhives folder don't see new mail indications and what not when mail is delivered there. Is there a better way to set the \Seen flag other than the global sieve script since it can be overridden by the user? -- J.P. Trosclair

[Dovecot] tls and auth plain login
by Bradley Giesbrecht 04 Mar '09

04 Mar '09

Hello List, I want to allow plain text passwords only on ssl/tls. Is it possible to have: auth default { mechanisms = cram-md5 ntlm ...... } and then over-ride this when connection is ssl/tls to allow plain and login? I have tried adding "mechanisms = plain login cram-md5 ntlm" to "protocol imaps{}" as an example but I get an error that the protocol does not exist. I read somewhere today that dovecot enables plain automatically over secure connections (ssl/tls) but I'm not seeing it. Also, "auth default" suggests that "auth something_else" is possible. I'm probably just doing a poor job of research but I'm not finding the answers I'm seeking. Using postfix and lda. # openssl s_client -connect localhost:993 # a01 capability * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST- EXTENDED I18NLEVEL=1 AUTH=CRAM-MD5 AUTH=NTLM a01 OK Capability completed.

[Dovecot] problems with dotlock
by Mark Hedges 03 Mar '09

03 Mar '09

I have to make dotlock work because this openwebmail thing only supports one of dotlock or flock, but procmail delivery does dotlock and fcntl. procmail correctly creates a dotlock file in /var/spool/mail/username.lock when delivering, I can watch this with `while :; do ls -la | grep lock; done`. It works fine when lock_method=fcntl, but no dotlock file shows up in /var/spool/mail. mbox_write_locks are working correctly with mbox_write_locks = dotlock fcntl, the dotlock file shows up in the user's mail directory. However, dotlocking /var/spool/mail doesn't work: $ ls -la /var/spool/mail total 44 drwxrwxr-x 2 root mail 4096 Feb 25 17:39 . $ grep mail_privileged_group /etc/mail/dovecot.conf mail_privileged_group = mail Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Effective uid=511, gid=100 Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: data=/home/anubis/despam_test_anubis/mail:INBOX=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: root=/home/anubis/despam_test_anubis/mail, index=/home/anubis/despam_test_anubis/mail, inbox=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): file_lock_dotlock() failed with mbox file /var/spool/mail/despam_test_anubis: Permission denied Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Couldn't open INBOX: Internal error occurred.

[Dovecot] GSSAPI cross-realm still broken
by Bryan Jacobs 03 Mar '09

03 Mar '09

I've been trying to track down some problems with Dovecot in a Kerberos 5 cross-realm environment, and there seem to be a few issues. LOGIN/PLAIN work fine using pam_krb5, but GSSAPI is a bit harder to handle. On line 436 of src/auth/mech-gssapi.c, the authn_name and the authz_name are compared using gss_compare_name. This dates back to the message at: http://dovecot.org/pipermail/dovecot/2005-October/009615.html While everything within that message is true, as things stand, Dovecot is unusable in a cross-realm environment. When cross-realm tickets are used, the authn_name is "username@REALM" and the authz_name is "username" (or vice versa, I don't remember). The attached patch causes dovecot to display these two values in human-readable format to illustrate the issue. Because these two GSS names differ, Dovecot refuses to allow access in spite of the fact that krb5_kuserok would return TRUE. I am not the only one to have noticed this problem: http://dovecot.org/pipermail/dovecot/2007-July/023868.html http://dovecot.org/pipermail/dovecot/2007-October/026027.html Might I suggest that some more robust security checking be done instead of abusing gss_compare_name like this? I don't know how to do this using GSSAPI, but on the Kerberos side Heimdal provides the function krb5_kuserok. Dovecot could also just have a configurable file listing acceptable krb5 principals (preferably in .k5login syntax) and check that both auth_name and authz_name are in the list. Bryan Jacobs

[Dovecot] Anyone know or have a perl, c/c++ script?
by Brandon Lamb 03 Mar '09

03 Mar '09

Hello all, Im hoping maybe someone on this list has already looked for or built something similiar. Basically from what I can tell, phps imap libraries or whatever dont support setting custom keywords. So I am wondering if someone has a library or script that can take a username, domain, password, folder, uid and flag to set so that my webmail app can call this to set imap keywords. So far my google searching isnt turning up anything, but searching for the word keyword doesnt really help.

[Dovecot] Seperate auth per protocol (pop3/imap)
by Guy 03 Mar '09

03 Mar '09

Hi, During discussions with the boss we've speculated about having users having only specific services available. One of the ideas was to have users being able to specify if they wanted POP3 or IMAP and whether we could limit their access to one or the other server side. We use MySQL for the userdb and passdb lookups at the moment. Is it possible to specify separate auth files with different MySQL lookups per protocol? Thanks Guy -- Don't just do something...sit there!

[Dovecot] dovecot imap and thunderbird tags
by Lorenzo Bettini 02 Mar '09

02 Mar '09

We've been using an imap(s) dovecot server for a while on an ubuntu 8.04.2 and we noted that tags set by thunderbird ("important", "to do", etc.) are almost always lost, i.e., when connecting to the same imap account from another machine, the tags are not there anymore... this always happens for the Inbox, and seldomly for other imap folders... anyone else experiencing this?

[Dovecot] Maildir format use question
by Rick Romero 02 Mar '09

02 Mar '09

Hey all, I've got a couple servers using Maildir format. As I understand it from a simple perspective, 'new' contains newly delivered messages, and 'cur' contains messages that have been 'handled'. I like to keep things simple for users, so rather than have 'Spam', 'Junk' 'ToLearn' and other possibly confusing folders, what I thought I would do is scan their .Spam/cur folder for mail that was older than an hour (based on file atime(?) stamp) and feed that through SpamAssassin. The idea being that anything in 'cur' would: 1. have been moved there by the user. 2. be recently read, and I think if it were innocent, would be handled within an hour 3. Not contain newly delivered, unread mail. This is actually what I see when I view my Spam folder through Evolution. If I use a PHP webclient - either Horde or Roundcube (I've captured the debugs if you'd like them), then a simple view of the Spam folder causes the files to be moved from new/ to cur/. They are updated with the :2, - but since nothing was actually done, no flags are added. So I'm left with a quandry. I guess the simple question is, Should mail in cur, EVER not have a flag? I suppose if it were marked as UNSEEN after being SEEN, that's possible. So I just answered myself there :) Is it possible to have Dovecot NOT move a file from new/ to cur/ until a flag has been assigned to the mail? Just from a, possible, performance standpoint - it seems when accessing an INBOX from a PHP webmail system with MANY new mails, there is an unnecessary(?) mass move of these files to another folder. Thoughts? Rick

Since it's a production server and I just started working for these people, I'll try to reproduce the previous error without affecting the users e-mail (since their server is now running 1.0.15). As soon as I do that I'm going to give you a feedback for sure, if the problem persists or not. The user who reported to me the error may not have the messages that were triggering the errors, so I can't guarantee that I'll be able to reproduce the error again.

[Dovecot] Forwarding with Dovecot
by Sawtooth500 02 Mar '09

02 Mar '09

I'm using Dovecot with Postfix as my MTA I need to set up forwarding with Dovecot. I create a .forward file in my user's home directory, and in the .forward file I put destination_email_address email(a)example.com. Well, it got delivered to the forwarded email just fine. But the sender also got an undeliverable email from the dovecot mailbox and a copy was not saved in the dovecot mailbox. I need emails forwarded, and a copy saved in the dovecot mailbox. Thanks in advance for the help! -- View this message in context: http://www.nabble.com/Forwarding-with-Dovecot-tp22244316p22244316.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Remote storage
by Daniel L. Miller 01 Mar '09

01 Mar '09

What options are available for remote storage, i.e. storage devices directly mounted on the machine running Dovecot? I've seen discussions of NFS usage - but my experiences with NFS in times past have been poor. CIFS has worked well for me for non-mail use - would this be suitable? Or is there another method I've not considered? -- Daniel

[Dovecot] Compilation Issue on Old Boxes with macro in src/master/main.c
by Kevin A. McGrail 28 Feb '09

28 Feb '09

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box. The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure --with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d --sysconfdir=/etc --localstatedir=/var I've used this to compile on other older boxes with success. And I compared the command lines and they are identical. This is the error I get with src/master/main.c main.c:365:1: directives may not be used inside a macro argument main.c:364:16: unterminated argument list invoking macro "printf" main.c: In function `print_build_options': main.c:372: syntax error before string constant Changing the function to a simpler function without the ifdef's resolves the issue and dovecot compiles. I would really like to know why two boxes with the same compiler are failing on one but not the other. Perhaps there's some program or library or preprocessor or path or something out of whack. Especially since using gcc 2.96 on the same box works! However, I since this is a simple options output routine and (from my cursory read) there may be some standards issue with this technique, I've also patched the issue. http://www.peregrinehw.com/downloads/dovecot/dovecot-1.1.11-build_options_m… Thoughts?

28 Feb '09

Hello, Im using Ubuntu 8.10 with Dovecot 1.0.10. I am using passwd files, not a MySQL database. I have 2 files, a "users" file, and a "passwd" file.

[Dovecot] Custom flags in v1.0.15
by Pascal Mouret 28 Feb '09

28 Feb '09

Hello all, I'm having problems with setting custom flags on a dovecot imap setup, with mbox mail store. I was running v1.0rc15 on a Debian Etch box, upgraded recently to v1.0.15, but nothing changed. The problem : I read my mail using IMAP. In Thunderbird (various versions, current one being v2.0.0.19), I can set various message flags (Important, Personal, Work, ... mapped to IMAP as $Label4,$ $Label3, $Label2, ...). I read my mail from several machines, but all changes made on the message flags from one machine won't appear on the others !? Still I've read that those flags are supported in Dovecot. Actually, I logged the IMAP traffic, and saw that Dovecot claims to "handle" them. For instance, I added a flag to a message : Thunderbird > 621 uid store 35150 +FLAGS ($label4) Dovecot > * 6716 FETCH (UID 35150 FLAGS (\Seen \Recent $Label4)) Now, if I close TB, so that changes are written to the mbox file, and if I open that file on a the server with any text editor, the 'X-Keywords' line doesn't appear !? And as a matter of a fact, if I read my mail from any other machine, the flag isn't set ! Anyone knows where the problem can be ? Do I need to upgrade to v1.1 ? Or are custom flags actually supported in v1.0 (which I believe is the case) ? I browsed through the internet and searched the archives of this mailing list but didn't find any clue ...

[Dovecot] Dovecot + Postfix Mail Forwarding Question
by Taras Hryniw 28 Feb '09

28 Feb '09

I have dovecot and postfix set up on debian lenny. Squirrelmail is used to access the mail. I put a .forward file in my user's home directory, and that sure gets the job done of forwarding email, but I need a copy saved on the local machine as well. How do I do that?

This: Feb 16 10:05:56 server dovecot: Panic: IMAP(user): file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) auth-worker died. That happened with Dovecot 1.1.4, 1.1.7 and 1.1.11, 1.1.7 was not with me, was with another user I found, on some mailing list. The problem occurred when copying or deleting messages, sometimes even viewing (Webmail). Since it's a production server, I compiled the latest 1.0.x and I'm using it. This particular server was running Ubuntu 8.04 (the default package is 1.0.x) and I upgraded to 8.10 (the default package is 1.1.x). > > > Is it possible to have Dovecot on one machine serving two different domains? > > Set up how? Do you want to use user@domain style usernames, or do you > want Dovecot to detect the domain based on the server's IP address? One dovecot server which receives mail to two domains and does not forward the mail anywhere, it's the final destination for the two of them. I already have usernames that are unique, by using Dovecot variables I have username~domain.org as the actual username/mailbox name. I want to have two mailbox roots, this way, even knowing that mailbox names are unique (john~domain.org != john~anotherdomain.org) and when authenticating (from what you wrote down here about passdb) john(a)domain.org will not be confused with john(a)anotherdomain.org, even so, I want all mailboxes from one domain to sit on a different mailbox root. > > > Is is possible to set a LDAP config to one domain and another > > LDAP config to the other (the auth part, I wan't users to reside > > on different bases on my LDAP tree, so search bases need to be > > different) > > Yes. You can just create two passdb ldap {}s. Ok, so, I have 3 aspects to consider: a) When mail arrives b) When user logs in to check mail c) Where mailboxes are located a) Since I can make mailbox names unique with Dovecot variables (mailbox name is "susan~domain.org" which is different from susan~anotherdomain.org) when mail arrives, the mail message will be saved to the correct mailbox (even if I have, under the same mailbox root, two users with "susan" as the login, but from different domains). b) Since you said, on Dovecot 1.0.x, I can have two passdb ldap{}'s, when the user logs in, he/she will be redirect to the right mailbox, not the "other susan". c) Ok, the two above give me the possibility to have all mailboxes, from the two domains, under the same mailbox root, users will be unique no matter the scenario (mail arriving, user checking mail), BUT, I would like to keep them separated anyways, is that possible to force that? > thanks! = Miata Convertible Tops Buy manufacturer direct from gahh, leader in high-quality convertible tops using original materials and attachments.

[Dovecot] Quota + Sieve
by Linux Advocate 27 Feb '09

27 Feb '09

Thanx to everybody's help , i have got a working combination of; - dovecot LDA - smtp auth thru dovecot sasl - postfix - virtual users in mysql - postfixadmin - thunderbird as the email client Just 2 additional questions - A. Sieve .............. With the imap filters in thunderbird, do i need to use sieve in dovecot? my initial observations/ findings say "no"? B. Quota ............. If i have not set quota in dovecot or postfix ( no quota related configuration ), may i then assume, the users have "unlimited storage" , limited only by the hardware/filesystem? I would like to have this feature ( just like unlimited storage in yahoo ) and just have a cron script running regularly to delete old emails ( for middle level, low level users ). Is such a strategy ok? regards, mgomez

From there it didn't take long to figure out that something had changed with update of Dovecot that no longer allowed this configuration line to work: mail_location: ~/Maildir and both in dovecot.conf and log I was warned to add the prefix "maildir"" With this everything seems to be fixed. I don't know whether this would be considered any kind of bug. The Debian package allowed me to upgrade Dovecot without warning me that the rules for mail_location had changed.

Hi, Here's the scenario. I want to set up a mailbox so that when mail sent to the address is piped to a processing application, instead of going to a mailbox. One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx -Mike

[Dovecot] exim4 + dovecot + SquirrelMail virtualhosted on Debian
by Tim Legg 25 Feb '09

25 Feb '09

Hello, I have a Debian machine that is virtual-hosting 6 domains with exim4. I finally got exim4 working well enough where I can send and receive mail using the mail command on my machine. I would eventually like to have SquirrelMail (which requires IMAP) working on my website. For whatever reason, exim4 doesn't seem to support IMAP. I found out that Dovecot is a prominent IMAP server. So I installed the most current Dovecot package (1.0.rc15) in Debian. Something is broken though... As I log into SquirrelMail, I get an error message "Error connecting to IMAP server: localhost. 111 : Connection refused". To investigate, I decided to telnet localhost on port 143 and found out that yes, the connection is in fact refused. So what do I need to do in order to have dovecot listen on port 143? Also, I noticed when I restart dovecot... debian:/etc/dovecot# /etc/init.d/dovecot restart Restarting mail server: dovecotError: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory I hope this isn't a serious problem. Thanks Tim Legg

by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi list I am just experimenting with seting up my own email server. I want some tips and hints on how to secure my setup to prevent unauthorised assess to my email. I have read through the wiki and have not found many tips. I hope to improve the wiki with tips gathered from the emailing list. :-) A basic measurement I could take right now would be to set more secure file premissions on my setup. My setup is based on http://wiki.dovecot.org/HowTo/VirtualhostingWithExim with a few addittions: fetchmail and exim4 deliver mail to my maildir and dovecot grants me access through imap. dovecot authenticates against /home/postmaster/passwd.digest and ./passwd.cram -- Daniel Aleksandersen <aleksandersen(a)runbox.no>

[Dovecot] Calling dovecot deliver from procmail
by Harry Lachanas 25 Feb '09

25 Feb '09

I came up with this trick That is Since my previous mail server had a bunch of complex procmail recipies and I am not sure that I can turn them into sieve scripts I am calling dovecot deliver to drop mail in it's final $DEFAULT destination. :0 | /some/path/dovecot/deliver in order to update the index, control files etc upon delivery time. So far in my "tests" it works. But I wonder if this is wise or not. Regards, Harry.

[Dovecot] Dovecot problem after last Debian sid update
by Paul Scott 25 Feb '09

25 Feb '09

Hi All, After upgrading dovecot for sid Thunderbird no longer displays the contents of any emails I have had a working IMAP setup for as much as a year even though I don't understand dovecot configuration well enough to know how I got it to go in the first place. Here is the output of dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: ~/Maildir auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd TIA for any clues as what to do next.

[Dovecot] OT: Fixing Messages To Be RFC 2822 Compliant
by Neil 25 Feb '09

25 Feb '09

So....apparently I have some messages which are not RFC compliant sitting in my mailboxes (mostly older ones), and I have some software which is refusing to handle such messages. 1. Does anyone know of a nice way to verify that all my messages are compliant/find those that aren't? (I suppose I could use the existing failing software, but I was hoping for something a little more robust...) 2. Does anyone know of any tools that will do The Right Thing as far as fixing these messages are concerned? Googling didn't turn up much for me, but maybe I wasn't hitting the right terms ("RFC message repair", "fix email message", etc.). Thanks.

[Dovecot] Rename INDEX
by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi I think there is a technical reason for this, but I am not sure. My IMAP client shows a folder called INDEX. This is my maildir. I wonder if it is possible to change the name of this folder to something else? -- Daniel

[Dovecot] Read-Only IMAP
by Neil 24 Feb '09

24 Feb '09

Inspired by the "Dovecot as a email storage system" thread... Is there a way to instruct Dovecot go into read-only mode for an account, or a mailbox? Could I maybe fake it by setting perms on the maildir directory to 440?

[Dovecot] Dovecot as a email storage system
by Roderick A. Anderson 24 Feb '09

24 Feb '09

I was thinking about all the old email I have and don't want to get rid of and how much space it is taking on my mail server. The idea came to me to install Dovecot on a server at home then I could drop mail into I want to save. It doesn't need to receive mail except what that is moved to it. Anyone see problems with doing this? Thanks, Rod --

[Dovecot] email stuck in outbox
by barnaby cockcroft 24 Feb '09

24 Feb '09

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users. We haven't ruled out a layer 2 issue but nor have we found one.... If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated. Dovecot version(s) 1.19 & 0.99.11 Configuration from 1.19: # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release 4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd

[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

[Dovecot] Postfix LDA vs the Dovecot LDA + other quetions
by Linux Advocate 24 Feb '09

24 Feb '09

Guys , 1. What is the benefit of using Dovecot' LDA as compared to postfix's LDA? Will there be better performance? And along the same vein, 2. What is the benefit of using Dovecot's SASL as compared to Cyrus SASL? Is there better performance? 3. Quota Management ( Creating, enforcing, notifying ) - is it done thru dovecot or postfix or are both needed? Regards, mgomez

[Dovecot] pkgsrc-ing sieve and managesieve
by Edgar Fuß 23 Feb '09

23 Feb '09

I'm trying to integrate both the new sieve implementation and managesieve into pkgsrc. Managesieve seems to need some dovecot libraries that dovecot doesn't install (lib-storage/libstorage.a, lib-auth/libauth.a, lib-imap/libimap.a, lib-index/libindex.a, lib-mail/libmail.a, lib-charset/libcharset.a, lib-dict/libdict.a and lib-charset/libcharset.a). There seems to be no provision in pkgsrc for the build of a package needing the work directory of the build of another package. Would it make sense for dovecot to install those libraries?

[Dovecot] sieve-test again
by Ian P. Christian 23 Feb '09

23 Feb '09

I'm not sure what it is I'm doing wrong here, perhaps my 'test' mail is not in the format expected by sieve-test. The 'test' file is a file taken directly from a dovecot maildir - so is in the normal format of having headers, a new line, then the body. There is nothing exceptional about this email. Notice how the header below is 'innocent', however it appears that the test is ignoring this header. # grep DSPAM-Res test X-DSPAM-Result: Innocent # cat sievetest require ["regex", "fileinto","envelope","reject","vacation","relational","comparator-i;ascii-numeric"]; if header :contains "X-DSPAM-Result" "Innocent" { fileinto "moo"; stop; } # sieve-test -c ./sievetest ./test Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success I don't think it's this header, but rather *all* headers, as the following check also appears to fail. if header :contains "To" "o" { fileinto "Spam"; stop; } Am I mis-using the tool? Thanks, Ian

[Dovecot] lda catchall
by Stéphane Cottin 23 Feb '09

23 Feb '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using dovecot lda in a qmail / vpopmail testing environnement. I would like to replace vpopmail lda with dovecot's one , because of quotas , sieve filers, indexing while delivering ... Everything is working great, except the catchall. If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda. How can I set a catchall email address for dovecot lda ? thx Stéphane Cottin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmixCcACgkQNgQUYqHIqqvttQCfcNBLd9Qo06g5nMcrfZAwVlpv WegAnj7jIA/XFJWmt/2jkg1sxRYKRaI7 =JTTV -----END PGP SIGNATURE-----

RETURN (PARTIAL) from CONTEXT=SORT that allows windowing SORT results) - pop3: If client idles for 10 seconds, commit transaction (allowing mbox to become unlocked). - crashfixes to virtual mailboxes - all kinds of bug fixes, error message improvements, etc. - http://dovecot.org/patches/1.2/stats-plugin.c may give some interesting statistics about commands There isn't really much left to do for v1.2.0 except some small fixing to shared mailbox code. And writing documentation for it..

[Dovecot] IMAP ACLs and global ACLs in v1.2
by Timo Sirainen 23 Feb '09

23 Feb '09

I just committed code for IMAP ACL support based on the code from Kolab people. I did quite large changes though. I also changed how global ACLs are handled. Previously local ACLs could override global ACLs, but now that users are able to modify the ACLs I think it should be the other way around. From what I've heard global ACLs are typically added for things like 1) disallowing user from doing something in specific mailboxes such as expunge messages, 2) giving a specific master user access to some mailboxes ONLY, such as voicemail. For 1) case a user really shouldn't be able to grant himself privileges back but still should be able to share the mailbox to others (so the global ACL should have 'a' privilege). For 2) case a user shouldn't be able to remove privileges from the voicemail. So now the user can freely update the local ACLs in whatever way he wants. But in the end if there are any global ACLs, all the local ACLs for those identifiers are ignored. Also local negative identifiers are ignored, so that e.g. global "user=foo lr" can't be disabled by a local "-user=foo lr" ACL. I guess I should update the Wiki ACL page about how exactly the ACLs are applied now that they're well in my memory. :) One thing I'm not really sure about is the "owner" handling. IMAP ACL specifications have no such concept. I think many/most other servers simply add a default ACL for the user name directly. It's a useful concept though, especially with the global ACLs. So currently Dovecot replies: x getacl inbox * ACL "inbox" "owner" lrwstiekxacd x OK Getacl completed. But should it just internally convert "owner" to "username" when replying? But then again if there's a separate rule directly for the "username" it breaks. Do any of the existing ACL-capable IMAP clients want to see the username in the ACL reply or can they handle "owner" just fine? Also what about global ACLs? The current code just lists them twice with local ACLs, which is definitely wrong: x getacl foo * ACL "foo" "xx" w "xx" lr "owner" lrwstiekxacd x OK Getacl completed. Perhaps the global ACLs could have a prefix character? Maybe '#'? Which reminds me, the current dovecot-acl file is mapped to IMAP ACLs like this: dovecot-acl : IMAP ACL - anyone : anyone - authenticated : authenticated - owner : owner - user=name : name - group=name : $name - group-override=name : !$name So all global ACLs would get the # prefix, like #anyone, #name, #!$name. Any thoughts? BTW. Listing shared mailboxes still doesn't work. I guess we'll see tomorrow if I still have energy to get that done.

[Dovecot] dovecot auth
by ben 23 Feb '09

23 Feb '09

Hi, I'm using dovecot with a passdb-file . When I login using : test(a)testdomain.com I notice dovecot strips off the domainname and looks up everything in front of the @ in his passdb-file... So I went on to configure the following in my dovecot.conf : auth_username_format = %u@%d restarted dovecot, but he still strips of the @ and the domainname ... LOG (sorry for f* up format) : dovecot: Feb 21 12:15:08 Info: auth(default): new auth connection: pid=24483 dovecot: Feb 21 12:15:12 Info: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=195.207.136.102 rip=195.207.136.108 lport=110 rport=36132 resp=AGJlbkBpdHV4LmJlAHRlc3QxMjMu dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): lookup: user=test file=/opt/dovecot/etc/dovecot.passwd dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): unknown user dovecot: Feb 21 12:15:14 Info: auth(default): client out: FAIL 1 user=test(a)testdomain.com Can someone enlighten me on how to config it so he looks up "test(a)testdomain.com" fully ? thx

[Dovecot] TLS / Dovecot / POP3
by John Espiro 22 Feb '09

22 Feb '09

I am using Thunderbird 2.x as my client, Dovecot on the server (POP3 not IMAP). Currently I have in my conf file: protocols = pop3s pop3 ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes login = pop3 In Thunderbird, I have the email server setup to: - Port 110 - TLS Here's my question: If I change protocols = pop3s pop3 to protocols = pop3s I can no longer connect to my mail server via Thunderbird unless I setup Thunderbird to use SSL. Am I doing something wrong? Thanks, John
