Description of problem: Hello, I am having problems with Dovecot not delivering 'big' emails. Small email with 1-2 kb text delivered fine. If the message about 200kb long or more it freezes.

Should I just make Dovecot lowercase usernames by default in v2.0? auth_username_format = %Lu Does anyone actually want to use non-lowercase usernames?

[Dovecot] Sieve on full mailbox
by ian＠comtek.co.uk 10 Jul '09

10 Jul '09

Hi, We are using dovecot with "mail_plugins = cmusieve". I have Avelsieve in SquirrelMail for users to interact with it. Is there any way I can allow users to run their sieve script on an entire mailbox? While the normal case of having messages filtered as they are delivered to the Maildir makes sense it would be useful for a few users to be able to apply their rules to every message on a one-off basis. If there is a binary which will do this job? I could adapt the SquirrelMail interface to invoke it with appropriate arguments. Thanks, Ian

[Dovecot] Dovecot delivering mail in the wrong directory location
by Tjerk Wolterink 10 Jul '09

10 Jul '09

Hello everybody,my new server is setup with postfix as a MTA and dovecot as a MDA, mysql is used as a user db, and postfixadmin is used to setup accounts. Login via pop works fine, also sending via smtp works fine. HOWEVER: when i sent a mail by hand via smtp it is delivered in the wrong directory. For example for test(a)xdatasystem.com i have the following directory: /home/vmail/xdatasystem.com/test However the mail is delivered to this directory: /home/vmail/test(a)xdatasystem.com/ I cannot figure this out as dovecot is correctly configured. ( think) Here is the important part of my dovecot.conf (sorry for the indents): === DOVECOT.CONF === *disable_plaintext_auth = no* *log_timestamp = "%Y-%m-%d %H:%M:%S "* *mail_location = maildir:/home/vmail/%d/%n/Maildir* *mail_access_groups = vmail* *first_valid_uid = 100* *first_valid_gid = 100* * * *protocol imap {* *}* * * *protocol pop3 {* *pop3_uidl_format = %08Xu%08Xv* *}* *auth default {* *mechanisms = digest-md5 plain* *passdb sql {* *args = /etc/dovecot/dovecot-sql.conf* *}* *#userdb sql {* *#args = /etc/dovecot/dovecot-sql.conf* *#}* * * *userdb static {* *args = uid=vmail gid=vmail home=/home/vmail/%d/%n* * }* * * *user = root* *}* === DOVECOT.CONF === Has anybody a clue?

[Dovecot] Optimal quota method for SQL
by Tom Sommer 10 Jul '09

10 Jul '09

Hi, I just installed 1.2.0 and I'm gonna set up some quota on my vitual users. I' ve got dovecot set up as LDA, and currently I'm using the dict-mysql method described for 1.2.0, but it's not really working at all. Am I correct in assuming that with this method I can define the quota limit in my dict (sql field)? This is my current config: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { quota = dict:user::proxy::quotadict quota_rule = *:storage=0:messages=0 } protocol lda { mail_plugins = quota ..... } I want quota to be disabled unless otherwise specified in my SQL database. // Tom

[Dovecot] Managesieve fails to retrieve scripts > 8kB on Dovecot 1.1.16
by John Marshall 10 Jul '09

10 Jul '09

After some help with debugging tips on #dovecot, I have established that a sieve script on Dovecot 1.1.16 has to be less than 8kB in order to be retrieved by a managesieve client. I have been using managesieve for about 6 months over as many 1.1.n versions of dovecot as have been around during that time and hit this problem when I upgraded to Dovecot 1.1.16. I have gone back to Dovecot 1.1.15 and can once again manage my 9kB sieve script remotely. Symptoms were that managesieve login was OK but instead of displaying my sieve script, the script editing window was empty. After 30 seconds the client gave me a timeout message. If I entered a small script in the empty client edit window and saved it, the new, small script was saved to the server and became active. I could then successfully retrieve and edit that small script. I tried hacking a few lines at a time out of my 9kB script (locally on the server). When it was down to 8.4KB I still couldn't get it through managesieve. The next hack took it down to 7.7kB and I could get that through managesieve. So, I'm guessing there's a magic 8192 number in there somewhere - perhaps a buffer? Server dovecot 1.1.16 dovecot-sieve 1.1.6 dovecot-managesieve 0.10.6 FreeBSD 7.2 Client Thunderbird 2.0.21 Sieve 0.1.6 A special thanks to all who write this stuff: it's great! -- John Marshall

[Dovecot] First V1.2 compile questions
by Stewart Dean 09 Jul '09

09 Jul '09

1) I see that the --without-pop3d option has gone away. What does this imply, i.e why was that done? Is there some other way that you now avoid compiling the POP code? Are there any other discontinued options? 2) There was some talk a while back about changing how and where the plugins were to be built and their code located. Was this implemented? If so, is there any doc on it? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Long delay checking mail with POP w/plain auth
by david hardy 09 Jul '09

09 Jul '09

I just switched from UW-IMAP to dovecot, and it all went smooth, except now I get a 4-5 second delay after connecting to the POP3 server (IMAP is fine). If I switch to auth "mechanisms=login", it is instantaneous - the delay is gone.

[Dovecot] Problem with 1.2 and sieve: failed with unsuccessful implicit keep
by Julien Danjou 09 Jul '09

09 Jul '09

Hi, First, thanks for this awesome piece of software. I've just upgraded to latest dovecot, aka 1.2. I've a problem. I've started using Sieve, and everything works fine, I already received a thousand of mails without any problem. However, there's one mail which is stuck in the postfix queue because of that: Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): mkdir_parents_chown(danjou.info/jd/) failed: Permission denied (euid=8(mail) egid=8(mail)) Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): copy: i_stream_read() failed: No such file or directory Jul 8 18:47:51 prometheus dovecot: deliver(jd(a)danjou.info): sieve: msgid=? <1186f9b5-0529-4622-8f4a-58462f9a4bcb(a)svr-exchange.siege.ldlc.com>: failed to store into mailbox 'INBOX': Internal error occurred.

[Dovecot] System users, mbox format and global ACLs
by Axel Luttgens 08 Jul '09

08 Jul '09

I need some help here... ;-) I'm experimenting with global ACLs, but just fail to understand very basic behaviors. So, before digging into the source code, I would really be delighted if someone could immediately point a mistake I'm making and miserably overlooking. The output of dovecot -n is provided at the end of this email. Just in case, conforming to the suggestion made in http://wiki.dovecot.org/ACL , I've specified a CONTROL directory; but I get a similar behavior without it. As far as the acl plugin is concerned, I've just specified a directory for global ACLs; whether that directory is populated or not doesn't seem to have an impact on the observed behavior. Here's the structure of the test user's home directory: total 0 drwx------ 4 testuser people 136 26 jui 13:52 . drwxr-xr-x 3 root admin 102 19 mai 16:56 .. drwxr-xr-x 4 testuser people 136 28 jui 17:09 _mailboxes drwxr-xr-x 2 testuser people 68 28 jui 17:07 _mboxesctrl ./_mailboxes: total 96 drwxr-xr-x 4 testuser people 136 28 jui 17:09 . drwx------ 4 testuser people 136 26 jui 13:52 .. drwx------ 3 testuser people 102 19 mai 17:02 .imap -rw------- 1 testuser people 48685 25 jui 16:58 inbox ./_mailboxes/.imap: total 0 drwx------ 3 testuser people 102 19 mai 17:02 . drwxr-xr-x 4 testuser people 136 28 jui 17:09 .. drwx------ 5 testuser people 170 23 jui 18:02 INBOX ./_mailboxes/.imap/INBOX: total 88 drwx------ 5 testuser people 170 23 jui 18:02 . drwx------ 3 testuser people 102 19 mai 17:02 .. -rw------- 1 testuser people 1376 23 jui 18:02 dovecot.index -rw------- 1 testuser people 26624 28 jui 10:23 dovecot.index.cache -rw-rw-rw- 1 testuser people 10284 25 jui 17:57 dovecot.index.log ./_mboxesctrl: total 0 drwxr-xr-x 2 testuser people 68 28 jui 17:07 . drwx------ 4 testuser people 136 26 jui 13:52 .. I've tried various combinations of permissions and ownership, again without any obvious influence. The manual creation of directory ~/_mboxesctrl/.imap doesn't seem to be more helpful. So, let's go to the heart of my "problem": # telnet 127.0.0.1 imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. a1 login testuser ****** a1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in a2 list "" * * LIST (\NoInferiors \UnMarked) "/" "dovecot-acl-list" * LIST (\HasNoChildren \UnMarked) "/" "INBOX" a2 OK List completed. a3 logout * BYE Logging out a3 OK Logout completed. Connection closed by foreign host. And indeed, a file named "dovecot-acl-list" has now been created under the _mailboxes directory: ./_mailboxes: total 96 drwxr-xr-x 5 testuser people 170 28 jui 17:11 . drwx------ 4 testuser people 136 26 jui 13:52 .. drwx------ 3 testuser people 102 19 mai 17:02 .imap -rw-r--r-- 1 testuser people 0 28 jui 17:11 dovecot-acl-list -rw------- 1 testuser people 48685 25 jui 16:58 inbox This is the only file to have been created consecutively to the telnet session. Is such a file supposed to be created there? If yes, why? I would have tended to believe that it is more a server internal matter than a name having to appear in the namespace. More generally, is such a file supposed to be created at all? After all, the configuration doesn't explicitely mention per-mailbox ACLs at all... Anyway, this is what gets written in mail.log for the whole telnet session: dovecot[82305]: auth(default): new auth connection: pid=82374 dovecot[82305]: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=49879 resp=<hidden> dovecot[82305]: auth-worker(default): pam(testuser,127.0.0.1): lookup service=imap dovecot[82305]: auth-worker(default): pam(testuser,127.0.0.1): #1/1 style=1 msg=Password: dovecot[82305]: auth(default): client out: OK 1 user=testuser dovecot[82305]: auth(default): master in: REQUEST 8 82327 1 dovecot[82305]: auth(default): passwd(testuser,127.0.0.1): lookup dovecot[82305]: auth(default): master out: USER 8 testuser system_groups_user=testuser uid=2001 gid=2001 home=/Volumes/ALMbpSpare/ People/a/testuser dovecot[82305]: imap-login: Login: user=<testuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot[82305]: IMAP(testuser): Loading modules from directory: /usr/ local/dovecot-1.2.rc7/lib/dovecot/imap dovecot[82305]: IMAP(testuser): Module loaded: /usr/local/ dovecot-1.2.rc7/lib/dovecot/imap/lib01_acl_plugin.so dovecot[82305]: IMAP(testuser): Effective uid=2001, gid=2001, home=/ Volumes/ALMbpSpare/People/a/testuser dovecot[82305]: IMAP(testuser): acl: No acl_shared_dict setting - shared mailbox listing is disabled dovecot[82305]: IMAP(testuser): mbox: data=~/_mailboxes:INBOX=~/ _mailboxes/inbox:CONTROL=~/_mboxesctrl dovecot[82305]: IMAP(testuser): fs: root=/Volumes/ALMbpSpare/People/a/ testuser/_mailboxes, index=, control=/Volumes/ALMbpSpare/People/a/ testuser/_mboxesctrl, inbox=/Volumes/ALMbpSpare/People/a/testuser/ _mailboxes/inbox dovecot[82305]: IMAP(testuser): acl: initializing backend with data: vfile:/usr/local/etc/dovecot-acls dovecot[82305]: IMAP(testuser): acl: acl username = testuser dovecot[82305]: IMAP(testuser): acl: owner = 1 dovecot[82305]: IMAP(testuser): acl vfile: Global ACL directory: /usr/ local/etc/dovecot-acls dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls//.DEFAULT not found dovecot[82305]: IMAP(testuser): Namespace : Using permissions from / Volumes/ALMbpSpare/People/a/testuser/_mailboxes: mode=0755 gid=-1 dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/.temp.ALMbp.local.82375.f9efcb24711711fb not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/.temp.ALMbp.local. 82375.f9efcb24711711fb/dovecot-acl not found dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/INBOX not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/INBOX/dovecot-acl not found dovecot[82305]: IMAP(testuser): acl vfile: file /usr/local/etc/ dovecot-acls/dovecot-acl-list not found dovecot[82305]: IMAP(testuser): acl vfile: file /Volumes/ALMbpSpare/ People/a/testuser/_mboxesctrl/.imap/dovecot-acl-list/dovecot-acl not found dovecot[82305]: IMAP(testuser): Disconnected: Logged out bytes=23/431 Why does the server seem to expect to find a temp file under ~/ _mboxesctrl/.imap?

[Dovecot] Problem with sieve and german umlauts
by M. Bobkiewicz 08 Jul '09

08 Jul '09

Dear list, I?m running a postfix (2.5.6) / Dovecot (1.1.11) on a Centos 5.2 box. I?ve written a small gui application to simply create Out of Office replys with sieve. The resulting code did work with maildrop without any problems. Now sieve fails when it meets any german umlauts like ä or ü. It just stops compiling the scripts and complains about the missing "};". A simple fix is to just replace the umlauts, but that doesn?t meet the expectations of my users. Is there any escape code I could use or any way to place the mail text outside the script? Best regards, Mike

During the whole telnet session, both files "new1" and "new2" remained empty (i.e. no pseudo-message written to them), no uidvalidity-related helper file seems to have been created and no uidvalidity-related function seems to have been called. And clearly, both mailboxes "new1" and "new2" have received the same UIDVALIDITY. Those UIDVALIDITYs appear to be persistent; messages may be added to and deleted from those mailboxes, those mailboxes may be renamed... their UIDVALIDITY remain unchanged and equal to 1. In fact, any additional mailbox is created with that unique and persistent UIDVALIDITY of 1. Is this supposed to behave that way?

[Dovecot] Dovecot 1.2rc7 / Sieve Plugin problem / Namespaces
by reg9009 08 Jul '09

08 Jul '09

Hi, I've got a problem with Dovecot 1.2rc7 and a Sieve script which should store eMails in a subfolder. It always fails with Jun 28 14:56:43 deliver(): Error: sieve: msgid=<4A47687D.30903(a)some.domain>: failed to store into mailbox '': Invalid mailbox name Jun 28 14:56:43 deliver(): Error: sieve: script /home/dovecot/sieve/info/dovecot.sieve failed with unsuccessful implicit keep This is with dovecot-libsieve. Same happens with cmusieve, though the message is slightly different: Jun 28 14:55:39 deliver(): Info: cmusieve: Executing script /home/dovecot/sieve/info/dovecot.sievec Jun 28 14:55:39 deliver(): Info: sieve runtime error: Keep: Generic Error Sieve script: if header :comparator "i;ascii-casemap" :contains "X-Spam-Level" "*****" { fileinto "INBOX/Junk"; stop; } I tried "INBOX.Junk", "Junk", etc., but no success. Namespace section in dovecot.conf: namespace private { separator = / prefix = INBOX/ inbox = yes #hidden = yes #list=yes } Same configuration works with cmusieve and Dovecot 1.1.16. I assume some problems with the namespace separator. Anyone got any ideas or got sieve running with namespace separator "/" and prefix "INBOX"? Regards, Sebastian

[Dovecot] readdir and rename don't mix; patch included
by Mike Abbott 08 Jul '09

08 Jul '09

Enclosed please find a patch to dovecot-1.1.16 that fixes a common problem we see under load on Mac OS X and HFS+. The symptom is that sometimes readdir() returns EINVAL. The problem is that readdir() and rename() don't mix well, and maildir_scan_dir() renames messages from new/ to cur/. The solution I chose is just to retry scanning the directory, since code to rescan is already present. An alternative solution would be to read the entire directory first, then process the contents; that is, to do all the readdirs before any renames. The patch is like Apple's previous ones, all tagged with /*APPLE*/ and formatted to simplify our merges. Please reformat it as you desire. It should also apply easily to 1.2.0. --- dovecot-1.1.16/src/lib-storage/index/maildir/maildir-sync.c 2009-05-20 16:42:49.000000000 -0500 +++ dovecot/src/lib-storage/index/maildir/maildir-sync.c 2009-07-07 19:50:37.000000000 -0500 @@ -354,7 +354,8 @@ return -1; } -static int maildir_scan_dir(struct maildir_sync_context *ctx, bool new_dir) +static int maildir_scan_dir(struct maildir_sync_context *ctx, bool new_dir, + bool final) /* APPLE */ { struct mail_storage *storage = &ctx->mbox->storage->storage; const char *path; @@ -486,6 +487,11 @@ } } + /* APPLE - rename can cause readdir to fail with EINVAL; force + quiet rescan unless this is the final such rescan already */ + if (errno == EINVAL && move_count && !final) + move_count = MAILDIR_RENAME_RESCAN_COUNT + 1; + else /* APPLE reduce code deltas */ if (errno != 0) { mail_storage_set_critical(storage, "readdir(%s) failed: %m", path); @@ -772,7 +778,8 @@ that new/ dir is checked as well. it's a good idea anyway. */ unsigned int count = 0; - while ((ret = maildir_scan_dir(ctx, TRUE)) > 0) { + while ((ret = maildir_scan_dir(ctx, TRUE, + count == MAILDIR_SCAN_DIR_MAX_COUNT)) > 0) { /* APPLE */ /* rename()d at least some files, which might have caused some other files to be missed. check again (see MAILDIR_RENAME_RESCAN_COUNT). */ @@ -783,7 +790,8 @@ return -1; if (cur_changed) { - if (maildir_scan_dir(ctx, FALSE) < 0) + if (maildir_scan_dir(ctx, FALSE, + FALSE) < 0) /* APPLE */ return -1; }

Attached is a patch which in my environment (Linux/Heimdal 1.2.1) fixes cross-realm GSSAPI authentication. Changes it makes: 1. When using krb5_kuserok, do not call gss_compare_name to check that authn_name and authz_name are the same. Instead, make TWO calls to krb5_kuserok, one for each ID. If both IDs are acceptable, allow the login. 2. Disable checking that the name is a GSS_KRB5_PRINCIPAL_NAME, as this doesn't appear to be always the case for the authz_name. If I create a .k5login listing both username@REALM1 and username@REALM2, and make that file follow the appropriate security restrictions (world read, user only write permissions), this lets me use GSSAPI logins with principals from either REALM1 or REALM2. This leaves untouched the behavior in the case where krb5_kuserok is not available. Bryan Jacobs

[Dovecot] v1.2.0 released
by Timo Sirainen 08 Jul '09

08 Jul '09

http://dovecot.org/releases/1.2/dovecot-1.2.0.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.0.tar.gz.sig As promised. No changes since v1.2.rc8 (except packaged in OS X, since CentOS 5 autotools didn't add support for configure --docdir). Below are the largest changes since v1.1: * When creating files or directories to mailboxes, Dovecot now uses the mailbox directory's permissions and GID for them. Previous versions simply used 0600 mode always. For backwards compatibility dovecot-shared file's permissions still override these with Maildir. * SQL dictionary (quota) configuration file is different than in v1.1. See doc/dovecot-dict-sql-example.conf for the new format. * deliver -m: Mailbox name is now assumed to be in UTF-8 format, not modified-UTF7. Stephan Bosch's new Sieve implementation also assumes UTF-8 format in fileinto parameters. + Full support for shared mailboxes and IMAP ACL extension. The code is mainly from Sascha Wilde and Bernhard Herzog. + IMAP: Added support for extensions: CONDSTORE, QRESYNC, ESEARCH, ESORT, SEARCHRES, WITHIN, ID and CONTEXT=SEARCH. + SEARCH supports INTHREAD search key, but the rest of the INTHREAD draft isn't implemented yet so it's not advertised in capability. + THREAD REFS algorithm where threads are sorted by their latest message instead of the thread root message. There is also no base subject merging. + IMAP: Implemented imap-response-codes draft. + Thread indexes for optimizing IMAP THREAD command and INTHREAD search key. + Added userdb checkpassword (by Sascha Wilde) + Virtual mailboxes: http://wiki.dovecot.org/Plugins/Virtual + Autocreate plugin: http://wiki.dovecot.org/Plugins/Autocreate + Listescape plugin: http://wiki.dovecot.org/Plugins/Listescape

[Dovecot] rquota RPC with netapp filer
by Ralf Becker 07 Jul '09

07 Jul '09

Hello list, with dovecot 1.2 on AIX rquota RPC calls fail with quota-fs: remote ext rquota call failed: RPC: 1832-012 Program/version mismatch when using a netapp filer. This is what netapp says: Bug ID 97288 Title Support requested for rquota version 2 Bug Severity 5 - Suggestion Bug Status Closed Product Data ONTAP Bug Type NFS Description Linux has implemented its own extensions to the rquota protocol as a version 2 of that protocol. ONTAP only supports v1 as that is the only version defined by Sun, the owner of that RPC program number. Workaround - Fixed-In This bug is not scheduled to be fixed, you may opt to Version open a technical support case if you would like to contact Network Appliance regarding the status of this bug. A complete list of releases where this bug is fixed is available here. So this should be no AIX specific problem. Using the attached rquota.x fixes the problem. In addition you have to disable group quota checking by adding "user" to your "quota" definition. Otherwise you'll see: quota-fs: rquota not compiled with group support Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.
