[Dovecot] Feature Missing OUTBOX Folder
by Frank Doege 01 Jun '09

01 Jun '09

Hi Dovecot People, i have switched my system from courier-imap to dovecot and iam quite happy with it, the performance is well and i had nearly no problems. One little feature iam missing is in Courier i had a folder called "Outbox" there i could paste mails which i want to sent out. In some networks its not always available to sent mails via port 21, i know i could just set up my email server to another port but it was a nice feature. Is this a big afford or is it just alittle hack ? could it done via a little plugin ? Thanks Timo & all others for the great work ! Frank

[Dovecot] imap cann't read the mail that foxmail send
by wallace0615 01 Jun '09

01 Jun '09

Hi everyone: I use dovecot only as the imap server, For smtp and pop3, I use apache james. The dovecot version: 1.1.14 And the configuration is : protocols: imap ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: mbox:/usr/local/edupass/mail/repo/%u:INBOX=/usr/local/edupass/mail/%u auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf I have no porblems to login. When I use "telent host 25" to send a email, dovecot read it no problems. But when I use outlook and foxmail to send a email, dovecot cann't read the email data. I compared the data that using the two way to send, and found the reason: use outlook and foxmail: at the beginning of the eamil data is "From zxjteacher_SP_LZU <zxjteacher_SP_LZU@myserver>"; and if I telnet host 25 to send the mail: at the beginning of the eamil data is "From <zxjteacher_SP_LZU@myserver>", so I delete "zxjteacher_SP_LZU", dovecot read it out. "zxjteacher_SP_LZU" is because that outlook and foxmail need an account name to represent the eamil address. So, anyone ever confront with this situation? Any helps appreciate. Thx.

[Dovecot] Expire Plug-in stopped
by Matt Rude 01 Jun '09

01 Jun '09

Good evening, While working with Dovecot 1.2rc4 on Fedora 10, I have been trying to get the Expire plug-in to auto delete messages for us. When I run the plug-in with the test flag, I receive the following message: /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: amy(a)example.com/Trash: stop, expire time in future: 1242953758 All messages were deleted before the expire plug-in was added. I understand that dovecot will only expire messages after they have been in the trash or junk longer then the time in dovecot.conf. So I have let this fail since Monday, but continue to receive the same error. A quick grep for expire from my Dovecot logs doesn't show any output. Also, when I look up this error on google, I see other peaple who's output shows a real date (not 1242953758), how do I know when this date is?

[Dovecot] Assertion failure in maildir-mail.c for gzipped maildir files in 1.1.15
by David S. Madole 01 Jun '09

01 Jun '09

I attempted an upgrade from 1.1.7 to 1.1.15 and encountered an apparent regression in handling gzipped maildir files. I have tried to narrow down the conditions under which it happens and reproduce it with as simple a case as possible. The actual mail application that exposed this problem is Squirrelmail. Starting off with the index files removed from the "Folder" maildir directory: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 3 (RFC822.SIZE INTERNALDATE) * 3 FETCH (UID 3 RFC822.SIZE 1085 INTERNALDATE "04-Jan-2004 09:23:45 -0500") 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) Connection closed by foreign host. The fetch of message 3, which is not gzipped succeeds, but the fetch of message 4, which is gzipped, fails with the following assertion in the log: Panic: imap: user=x, Status: file maildir-mail.c: line 85 (maildir_mail_stat): assertion failed: (fd != -1) Repeating, but first fetching only INTERNALDATE from the gzipped message succeeds, and once that value is cached in the index files, the same query that causes the failure before will now succeed, as it doesn't need to read the gzipped file any more to get INTERNALDATE: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (INTERNALDATE) * 4 FETCH (UID 4 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) * 4 FETCH (UID 4 RFC822.SIZE 6035 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 4 OK Fetch completed. 5 logout * BYE Logging out 5 OK Logout completed. Connection closed by foreign host. Now that the value is cached, the same previously failing query will continue to execute fine, as long as the indexes remain in place: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (RFC822.SIZE INTERNALDATE) * 4 FETCH (UID 4 RFC822.SIZE 6035 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 3 OK Fetch completed. 4 logout * BYE Logging out 4 OK Logout completed. Connection closed by foreign host. Removing the indexes again, and this time first fetching just RFC822.SIZE first: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (RFC822.SIZE) * 4 FETCH (UID 4 RFC822.SIZE 6035) 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) Connection closed by foreign host. In this case, the assertion fails again. Fetching RFC822.SIZE alone does not populate the indexes in a way that then allows RFC822.SIZE and INTERNALDATE to be fetched, as fetching INTERNALDATE alone does. It's all confusing to me, hopefully this make some sense to others. Let me know if there is other testing I can help with. I'm running on Slackware 12.1 and have reproduced the same issue with both kernel 2.6.24.4 and 2.6.27.7. The filesystem is XFS. The content of the gzipped message does not seem to matter. David

[Dovecot] Missing IMAP folders after Server reboot
by Eoin Kennedy 31 May '09

31 May '09

Hi, Here is the situation, I hope somebody can help me. Our Email server running ubuntu 8.04.1 and dovecot 1.0.10 rebooted, and when it came back up the dovecot config had changed. Prior to the reboot, users stored their emails and folders in /var/mail/~username. Then the config became /var/mail/username for the main Inbox and /home/~username/mail for Folders. Now, none of the folders that users had created in their IMAP account are visible, and their contents are not in the main Inbox file. For example, the Drafts folder was there prior to the reboot, and now it had to be created in /home/username afterwards. These folders were not subfolders of the Inbox, but of the main IMAP root. All users were running Thunderbird as their client. Can they be recovered?

[Dovecot] antispam plugin and MUA-Junk folders
by Steffen Kaiser 31 May '09

31 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I have a configuration problem, that I ignored till now. Many MUAs tag SPAM themselves and move SPAM to a junk folder (Thunderbird uses "Junk"). It is said to not automatically train these mails, but let have an human revise them. Currently, I have configured those folders as "trash" folders for antispam, which means that those messages are essentially lost, because a move into a spam folder will not train them. -> The current antispam plugin ignores moves in and out of trash folders completely. I wonder why the move trash -> SPAM is ignored? If I configure those junk folders as "unsure" in antispam, the situation can happen, that an user selects a spam folder, the MUA identifies junk and moves the messages into its Junk folder. Current implementation would train this move as HAM. How about the following: 1) copy from * into trash or unsure -> not train 2) copy from !spam into spam -> train as SPAM 4) copy from spam or unsure into !(trash or unsure or spam) -> train as HAM 6) else -> not train Bye, - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQEVAwUBSh0PdHWSIuGy1ktrAQKmaAf/ew1SixCkkWD2V12Jfw3mLcWnUrUSRq/J nsyMkW2//tX74wSJeMjbzlEkxN3dyfJg7f4WviGPdnUp5sqNGuS9lBfHh3ShQHtt 30+mRzVqizmcNEXBFoZXVy1K5hE8p9ssN9avahmUejBVPaSZHD0OjN5h8nFkNMDI XHU2347g03zr1MxejinWyRiKt1MFQyyJ6Y7gXNf6yascWKJA8W6b4Zu/eIH5uEW+ yiMuweaxJOwuGcwqh/qSKZTXnoCLa9rzvd8i/uZGvn7AXoT5u4P5coZkIHrh64U7 oswuYAZwxkmjGNLdGrovZadRJym16BlfVHH5g3Zo7k4nwX+kGRKyug== =9b+n -----END PGP SIGNATURE-----

[Dovecot] offlineimap with dovecot and sieve

I have a dumb question, is it possible to use this combination: Synchronising a remote IMAP-server and a local dovecot-IMAP-server by offlineimap (with both types = IMAP), which works very well. But it seems, that my sieve-scripts on the local dovecot server are not recognised by this combination.

[Dovecot] (no subject)
by Patrick Hemmen 29 May '09

29 May '09

Hi, I use a OpenLDAP for authentication. To authenticate a full DN as the user name must be used, like "cn=jim,ou=users,dc=example,dc=com". There are several domains, like example2.com and example3.com. I want to use Dovecot with ldap and authentication binds. For testing I use "auth_bind_userdn = cn=%n,ou=users,dc=%d" and the user name must provide as "jim@example,dc=com". To allow the special chars ("=,") in user name, I extend "auth_username_chars". Now my questions. Exists a real chance to attack the ldap directory with the extended "auth_username_chars"? And it's possible to use authentication binds with the regular "auth_username_chars" and a provided user names like "jim(a)example.com" in my special ldap directory structure? Thanks in advance - Patrick

[Dovecot] Clustering dovecot?
by dovecot＠corwyn.net 29 May '09

29 May '09

Currently I have a mail server running postfix and dovecot with users in mysql. I have Outlook (blich) clients checking IMAP mail on the server. I'd like to build some fault-tolerance into that system in case I have hardware failure. I've read through: http://wiki.dovecot.org/MailLocation/SharedDisk but I feel I need more information. My basic understanding is that I'll need 2 clustered systems running with shared disk space and shared IP. Performance/load-balancing isn't an issue for me, it's just fault-tolerance that I'm worried about. I found a nice long doc for Cyrus IMAP (http://cyrusimap.web.cmu.edu//ag.html) anything similar for dovecot? Rick Rick Steeves http://www.sinister.net "The more I learn, it seems, the less I know."

[Dovecot] expire: mysql table creation error

Don't know if anyone found this already (couldn't see anything in the archives about it) but maybe this is useful to someone else who finds the same problem. When following the instructions for setting up expire on v1.2+ for mysql backend at http://wiki.dovecot.org/Plugins/Expire I got the following error: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox) -> ); ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes that's because it's a utf8 database where every char is 3 bytes so a 355 char index is 1065 bytes. it worked ok with the following modification: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) but maybe that's not such a good primary key, probably better to do: mysql> CREATE TABLE expires ( -> id integer not null auto_increment, -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (id), -> key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) John

Hi, Recently started receiving the error $SUBJECT. Soon after a number of segfault errors are reported for pop3-login. Based on my configuration, I believe I am set up to receive core files; however, my ulimit -c is 0. I have tried setting ulimit -c ... in /etc/init.d/dovecot and I have tried modifying /etc/security/limits.conf. In all cases /proc/[pid]/limits continued to report that my ulimit -c value was 0. What is the best process for capturing a core file from a login process (pop3-login). I have found some similar hits on the web for this; however, none appear to lead to resolution and in most cases the implementation includes imap, mysql, etc...

[Dovecot] Timeout during imapsync
by Craig Jackson 29 May '09

29 May '09

Hi, I'm using Imapsync to sync messages from an Exchange 2003 server to a Dovecot 1.1.11 server. The problem is that users' mailboxes are huge, several gigabytes with tens of thousands of messages. First Imapsync connects to Exchange and then to Dovecot, and then starts to get Inbox info from Exchange. By the time it gets this info, the connection to Dovecot has timed out. I realize the RFC calls for a 30 minute time out which I believe is hard coded into Dovecot. If there is a way around this by making a configuration change, please tell me. I have posted the same message on the Imapsync list in an attempt to find a work around with patched Imapsync. Thanks in advance. Craig Jackson

[Dovecot] dbox verses maildir - advantages/disadvantages

I am migrating our mail server from Courier-IMAP to Dovecot. We currently use maildir storage format. What are the advantages and disadvantages of Dovecot's dbox format over maildir? Does anyone have any performance benchmarks for both? What do people use to test performance? We are running on a Mac OS X box (10.5.7) using Postfix 2.6. Thanks, James.

[Dovecot] Dovecot and Phpgroupware compatibility
by Carlos Xavier 29 May '09

29 May '09

Hi, recently moved our server from mbox format to Maildir format. Almost all the users are very happy with this, since the speed had increased very much. I used mb2md to do the conversion and on this task all the mailboxes that had "." (dot) on their names were converted to "_". But there is one issue with this, we also use the webmail that comes with Phpgroupware, and it uses some mailbox that have fixed named like INBOX.Sent, INBOX.Draft and so on. When their names were changed the sent messages didn't get saved anymore, so I had to move them back to the old names. After that the sent messages returned to be saved again, but another troube showed up. As they start with .INBOX and have "." on the names, Dovecot shown them as a subdirectory of the INBOX and we got some people upset with this. I need help on configuring Dovecot to not show them this way, because if you look the .INBOX.Sent either on the webmail or by outlook, the field displayed is the sender, witch is not desired. When I did the conversion, to keep the compatibility with the old server (quota, avoid I/O botleneck, etc), I set two Maildirs, one at /var/spool/mail/$USER, to be the INBOX and another at the user home. We are using Dovecot version 1.1.13, and below is the relevant configuration on use. namespace public { prefix = "#mbox/" separator = / inbox = yes list = no location= maildir:/var/spool/mail/%u/:CONTROL=~/control:INDEX=~/control } namespace private { separator = / prefix = location= maildir:~/Maildir/:CONTROL=~/control:INDEX=~/control inbox = no } Best Regards, Carlos Xavier.

[Dovecot] Does a plugin can have root privileges ?

Hello, I wish to get "Fetchmail Wake" works in my environment. This plugin send SIGUSR1 to fetchmail so it wakes up when mail client grabs mail. For the moment "Fetchmail Wake" is executed by mail_uid (defined in dovecot.conf) which is not enough to send signal to fetchmail daemon (and access to fetchmail.pidfile). Thank you!

I'm seeing this message in my /var/log/maillog: May 26 12:35:00 agencymail dovecot: IMAP(info(a)example.com): Inotify instance limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances I rummaged through google, and found : http://www.dovecot.org/list/dovecot-cvs/2008-May/011132.html which says I need to increase /proc/sys/fs/inotify/max_user_instances (no surprise given the error message really). I can fix that with echo 256 > /proc/sys/fs/inotify/max_user_instances , but as /proc is temporary, so if I change it won't it break if/when the system reboots? The error message also implies that something has been disabled. If I increase /proc/sys/fs/inotify/max_user_instances will it fix automatically, or do I need to do something else? since it's a kernel message, I suspect just restarting dovecot won't do it. And what exactly is breaking when I receive this notification? The proc docs indicate: /proc/sys/fs/inotify (since Linux 2.6.13) This directory contains files max_queued_events, max_user_instances, and max_user_watches, that can be used to limit the amount of kernel memory consumed by the inotify interface. For further details, see <http://linux.die.net/man/7/inotify>inotify(7).

[Dovecot] A few easy pam and virtual domains questions
by Mauricio Tavares 29 May '09

29 May '09

I am using dovecot with postfix, which was setup to do virtual domains. Dovecot is setup to authenticate against pam (I know, I know) and knows to look for email in /var/spool/vmail/: virtual_mailbox_base = /var/spool/vmail I also have virtual_mailbox_maps defined as virtual_mailbox_maps = hash:/etc/postfix/vmaps.txt where I currently only have one account, % cat /etc/postfix/vmaps.txt raub(a)domain.com domain.com/raub/ % Inside raub we have the usual 3 directories, new,cur, and tmp. When I try to login through imap as raub@domain.com@mail.domain.com (i.e. since we are doing the virtual domain thingie, the username has to indicate the domain it belongs to), it will not take it. But, if I login as raub(a)mail.domain.com, it has no problems authenticating. However, it now expects to retrieve email from /var/spool/vmail/raub instead of /var/spool/vmail/domain.com/raub. Why would it be doing that? Could it be that pam reports raub to be a local account and as a result simply ignoring vmaps.txt? I asked dovecot to log everything it could. When I checked the log file, the following line screamed at me: dovecot: May 27 14:40:28 Info: IMAP(raub): maildir++: root=/var/spool/vmail//raub, index=, control=, inbox=/var/spool/vmail//raub Note the "//" in root and inbox declarations; between those slashes I would expect to be domain.com. Compounding the problem, and perhaps a clue of how pam is telling what these accounts are, postfix is completely ignoring /var/spool/vmail, placing the emails in /home/raub/Maildir (account is actually being nfs-automounted and user authenticated through ldap through pam). Once again I am guessing it too is being told raub is a local user; am I correct?

[Dovecot] What does "a" flag in Maildir format mean?
by Max Ivanov 29 May '09

29 May '09

Here is sample filename from Maildir: 1243423383.M745917P32169.termserv1,W=1295:2,Sa 1) why there is no S=<size> field? It definetely differs from 1295.I've not quota plugin, could it be the reason of this? 2) what does "a" flag mean? I not found any description of this neither in Maildir spec nor on the Dovecot wiki.

[Dovecot] RFC 3501 section 7
by Scott Haneda 27 May '09

27 May '09

Hello, been lurking a while, about to move over to Dovecot soon. I have a nice test machine up and running. My previous email server when talking IMAP to Apple Mail, will eventually go "deaf" and new messages will not make it to the Inbox of Apple Mail Client. A restart of the desktop application is required. I am told that the reason for this is that my current email server adheres to RFC 3501, specifically section 7, the second paragraph of which says: The client MUST be prepared to accept any response at all times. Apparently, Apple Mail is not adhering to that, and my email server is sending out that type of response. However, I look at this list, for which I am not entirely sure how accurate the actual test is: http://www.imapwiki.org/ImapTest/ServerStatus It lists Dovecot as one of only two that are fully compliant IMAP servers. Congrats on that. My questions are: Does Dovecot in fact support correctly the above mentioned RFC and subsection? I assume so. That being the case, I have not had issues in my testing of Dovecot, nor heard reports of Apple Mail and IMAP having any significant problems. How, if that is the case, can Apple Mail and Dovecot work well with each other, and my current email server is not able to? My primary reason for moving to Dovecot is to not be burdened by this issue, as well as have what I consider to be a more advanced storage mechanism for the actual messages. What I would like to avoid, is spending a lot of time migrating thousands of users to a new system, to only have them burdened by the same inability to have email come to them without an application relaunch. Thank you for any insight on this. * I have filed a bug report with Apple, which was accepted. Their system does not allow me to see the status on the report once it has been closed. -- Scott * If you contact me off list replace talklists@ with scott@ *

[Dovecot] Dovecot and Phpgroupware compatibility
by Carlos Xavier 27 May '09

27 May '09

Hi, I am resending this email, since the fist one didn't hit the list. Recently we moved our server from mbox format to Maildir format and started using Dovecot. Almost all the users are very happy with this, since the speed had increased very much. I used mb2md to do the conversion and on this task all the mailboxes that had "." (dot) on their names were converted to "_". But there is one issue with this, we also use the webmail that comes with Phpgroupware, and it uses some mailbox that have fixed named like INBOX.Sent, INBOX.Draft and so on. When their names were changed the sent messages didn't get saved anymore, so I had to move them back to the old names. After that the sent messages returned to be saved again, but another trouble showed up. As they start with .INBOX and have "." on the names, Dovecot shown them as a subdirectory of the INBOX and we got some people upset with this. I need help on configuring Dovecot to not show them this way, because if you reed the .INBOX.Sent either on the webmail or by Outlook, the field displayed is the sender, witch is not desired. When I did the conversion, to keep the compatibility with the old server (quota, avoid I/O bottleneck, etc), I set two Maildirs, one at /var/spool/mail/$USER, to be the INBOX and another at the user home. We are using Dovecot version 1.1.13, and below is the relevant configuration on use. namespace public { prefix = "#mbox/" separator = / inbox = yes list = no location= maildir:/var/spool/mail/%u/:CONTROL=~/control:INDEX=~/control } namespace private { separator = / prefix = location= maildir:~/Maildir/:CONTROL=~/control:INDEX=~/control inbox = no } Best Regards, Carlos Xavier.

[Dovecot] Secure Sockets Layer client certificate authentication
by Stephen Feyrer 26 May '09

26 May '09

Hi everyone. Please note, I've asked a very similar question before and I apologize for sounding like a broken record. Well here it goes. What I want to do is authenticate my users using a certificate. Thereby authenticating both the user and server with strong tokens that are centrally managed. In the worst case scenario the user should only need to enter a password for the certificate store and then the certificate should trigger the appropriate level of access to their account. Is Dovecot the correct tool for the job? If yes then, how? Else if not, then what would you recommend? I have tried setting the auth mechanism to anonymous without any joy. My password file is set with nopassword. All my certificates work well with the Secure Sockets Layer system.

[Dovecot] status=bounced (Command died with signal 11: "/usr/lib/dovecot/deliver"
by Chantal Rosmuller 26 May '09

26 May '09

Hi list, I use dovecot 1.1.11 on ubuntu 9.04, when I want to send a message to an email adres on this mailserver I get this error: status=bounced (Command died with signal 11: "/usr/lib/dovecot/deliver". The folders where the email should be delivered are created so it does not look like a permission problem. I connect to a mysql database where the email accoutn info is stored, this works. I use the same setup on an ubuntu 8.04 server with dovecot 1 and I have no problems on that server. What am I overlooking here?

Hi, does sieve plugin in 1.0.15 support fileinto subdirectory? There is a maildir .oss.dovecot and sieve rule: if envelope :contains "to" "k+dovecot" { fileinto "oss.dovecot"; } But I get LDA error: Couldn't open mailbox dovecot: Mailbox doesn't exist: dovecot Any suggestions? Delivery to non-subdirectories is working fine. Regards -- Karel

[Dovecot] libsieve problems / wishes
by Steffen Kaiser 26 May '09

26 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm trying libsieve (853:42e154b8792e) to cope with our current installation, the following issues arise: 1) vacation addresses are compared case-sensitivly, e.g.: vacation :addresses [ "Steffen.Kaiser(a)example.com" ] ""; it won't match "steffen.kaiser@...". attached patch makes a first shot about that problem, leaving: 1a) maybe one should lower-case :addresses argument at compile time and my_address at run-time and then use strcmp() again. 1b) duplicate checks are case-sensitive, too. This is probably no big issue, because if the same person uses different variants of his/her mail address for sending, s/he does not deserve better. 1c) Suppression of replies to own mails are case-sensitive, too. Well, many people I know test that "it just works" by sending themselves a mail. I would disable this check. 2) we have about 157 ways to write the domain part. Not all accounts are available in all of them, but it's close to it. The old vacation program we used prior to "cmusieve" didn't care about the domain unless explicitly given. It was quite painful. Attached patch adds a "domainless" variant of :addresses arguments in such way, that vacation :addresses [ "Steffen.Kaiser" ] ""; matches any domain. Ideally, it would be better to specify all valid domains, but perhaps one can leave that for another approach with a different syntax, e.g. with "@*" as domain? Maybe, there is a better approach. Now there is possibility that common local parts are matched from alien domains easily. If to specify a set of "default" domains would be an option for libsieve, what is the suggested way: - - as user-option via dovecot.conf? - - as admin-enforced Sieve-script that sets some internal variables? aka using the multi-script capability - - ??? 3) Because I try to migrate from cmusieve v1.0, I have a name issue with "imapflags". README sec "* Supports all extensions provided by the original CMUSieve plugin:" and sec "Implementation Status" explains that "imapflags" is available. This is not true entirly: "imapflags" is not, lib-sieve uses the name "imap4flags" as defined by RFC. So, it leaves me with two options: 3a) convert all user scripts and hack Horde-Ingo, or 3b) have libsieve accept the alias "imapflags" for the extension "imap4flags". Would it be worhtwhile for libsieve to implement aliases for extensions, so that they are available in require by more than one name? About Horde-Ingo, maybe they have an update to use "imap4flags", too, but it looks like that I upgrade Dovecot before Horde.

[Dovecot] Maildir with LAYOUT=fs not working
by Rich Wales 26 May '09

26 May '09

I'm considering converting a Cyrus system (managing my family's e-mail) to Dovecot. I'm trying Dovecot 1.1.15 on an Ubuntu 9.04 (2.6.28-11-server) system. My production server is currently running Cyrus 2.3.14. Since I have a huge number of folders and subfolders, I need to use LAYOUT=fs. However, it's not working consistently. I tried setting up a test account in Thunderbird (2.0.0.21), and I was able to create folders under the Inbox, and they showed up as nested subdirectories under my ~/Maildir on my mail server. So far, so good. However, when I tried a home-grown Perl script (an archival scheme for my work e-mail), Dovecot wouldn't create subfolders properly; instead of nesting them (as I thought LAYOUT=fs would do), it used a flat layout. Here is a trace (generated by my Perl script) of an IMAP session. This was supposed to log in as the user "stanford" (the name of my archival account); create a folder named "2009" if not already present; create (again, if not already there) a "2009-05" folder inside the "2009" folder; and, finally, save a message (marked as seen) inside the "2009-05" folder. 1 LOGIN XXXXXXXX XXXXXXXX1 OK Logged in. 2 STATUS user.stanford.2009 (MESSAGES)* STATUS "user.stanford.2009" (MESSAGES 0) 2 OK Status completed. 3 STATUS user.stanford.2009.2009-05 (MESSAGES)* STATUS "user.stanford.2009.2009-05" (MESSAGES 3) 3 OK Status completed. 4 APPEND user.stanford.2009.2009-05 (\Seen) {4043} + OK (message text here . . .) 4 OK [APPENDUID 1243306507 4] Append completed. 5 LOGOUT* BYE Logging out The above works perfectly when I'm talking to my Cyrus server. However, when I tried the same thing with Dovecot, I got a folder named "user.stanford.2009" in the "stanford" account's Maildir, and then another folder named "user.stanford.2009.2009-05" (again, in the Maildir -- NOT nested in the "user.stanford.2009" folder) -- and the message was stored in the "user.stanford.2009.2009-05" folder. I tried changing my Perl script to use "INBOX" instead of "user.stanford" -- but the result was basically the same, except I got new folders named "INBOX.2009" and "INBOX.2009.2009-05" directly in my archival account's Maildir. Finally, I tried omitting any prefix at all on the folder names, and I got new folders named "2009" and "2009.2009-05" -- again, directly in Maildir -- no nesting of one folder within another. I suppose I actually have two issues here -- the lack of folder nesting (even with LAYOUT=fs), and also Dovecot's failure to recognize a "user.XXX." prefix on a mailbox name as designating user XXX's inbox (something that seems to work fine on Cyrus). My Cyrus server currently has over 1,600 folders and subfolders, so I absolutely can't / won't consider switching it to Dovecot unless I can get the nested filesystem layout working. Any thoughts? -- Rich Wales / richw(a)richw.org / richw(a)stanford.edu Wikipedia: http://en.wikipedia.org/wiki/User:Richwales Facebook: http://www.new.facebook.com/profile.php?id=206680

[Dovecot] lda deliver per instance sieve configuration
by J.P. Trosclair 26 May '09

26 May '09

I'd like to override the sieve settings in dovecot.conf for a deliver instance that is being run from a custom archiving script. This is dovecot 1.0.15 on debian lenny. Is this possible? Doesn't appear to be looking through the WIKI. If it's not any suggestions? The problem is the user specific sieve scripts override where the archived mail is supposed to be stored (maildir:~/.Archives.YYYY-MM) so I'd like to disable their sieve scripts while the archived mail delivery via deliver is taking place. Thanks, J.P.

[Dovecot] Separate home and mail folders problem on delivery
by Николай Бочев 26 May '09

26 May '09

Hello, I am using dovecot 1.2rc series on my mail server combined with postfix ( virtual users with postgre ). I have setup separate home and mail locations. It works fine ( with sieve etc. ). The user home folders are in /home/vmail/%d/%n and mailboxes are in /srv/mail/%d/%n .

[Dovecot] convert-tool skip_dotfiles is not the actual option
by Kenneth Porter 26 May '09

26 May '09

Looking at the source for convert-tool.c, I see this: "Usage: <username> <home dir> <source mail env> <dest mail env>\n" \ " [skip_broken_mailboxes] [skip_dotfiles] [alt_hierarchy_char=<c>]" else if (strcmp(argv[i], "skip_dotdirs") != 0) set.skip_dotdirs = TRUE; Looks like the usage line needs to be fixed (dovecot-1.2-0.rc2).

[Dovecot] little problem with lmtp and 8bitmime mail from:
by ja nein 26 May '09

26 May '09

Hi all, I'm very excited to see lmtp in dovecot now. Starting to play, I encountered following problem: With senders in normal mail address format, everything is delivered right, lmtp works as expected. But with 8bitmime senders, like kernel mailing list, lmtp returns a 5.5.4 not supported and mail is bounced. Is this expected, meaning just not implemented, or could it be a bug? E.g.: Problem: MAIL FROM:<linux-kernel-owner+info=40xxxx.com-S1753112AbZEYPtt(a)vger.kernel.org> BODY=8BITMIME RCPT TO:<info(a)xxxx.com> DATA vstream_fflush_some: fd 12 flush 130 vstream_buf_get_ready: fd 12 got 89 501 5.5.4 Unsupported options Ok: MAIL FROM:<some.address(a)somewhere.com> RCPT TO:<info(a)xxxx.com> DATA vstream_fflush_some: fd 12 flush 71 vstream_buf_get_ready: fd 12 got 36 250 2.1.0 OK 250 2.1.5 OK 354 OK Dovecot version is latest hg dovecot-2.0 trunk. Regards, Sebastian

[Dovecot] Deleting mail account?
by David Reid 25 May '09

25 May '09

This is likely a daft question, but how do I remove a mailbox from a dovecot server? I'd like to simply remove it from the disk as well, deleting any messages, indexes etc etc Is there a way? david !DSPAM:1715,4a1a817434922186719589!
