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

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. Thanks for any answer, Javier

[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] hwo can i have managesieve protocol and cmusieve plugin work at the same time

[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] [patch] example configuration for expire seems broken
by Robert McQueen 06 Mar '09

06 Mar '09

The expire configuration in the example config file in 1.1.11 is broken: root@omega:/etc/dovecot# /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecot Unknown dict module: db expire plugin: dict_init() failed Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed! It's inconsistent with the documentation at http://wiki.dovecot.org/Plugins/Expire, so I've made the attached patch to try and fix it. Note: I don't know if this new configuration is correct either, because its a new box and I've not got any mails old enough to cause the plugin to try and write anything, but at least I can start dovecot like this. :) Regards, Rob

This is while the connection is open, immediately after deleting a message, before closing the connection. Same for IMAP and POP tests. # `ps axu | grep dove` # root 20392 0.0 0.0 1888 540 ?

[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? I wonder if the original bug reporter removed both the mailbox and the index files at the same time; the current explanation is less than satisfactory. Thanks, Alan Ferrency pair Networks, Inc.

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.

I tried making all of the binaries root:mail with g+s, same as /usr/bin/lockfile, but this was no help. It also does not help to chmod +t /var/spool/mail. $ dovecot --version 1.0.7 kernel 2.6.18-92.1.22.el5 centos mmap_disable = yes (req'd for ~/mail dotlocks, makes no difference either way for /var/spool/mail) Any ideas? Thanks, Mark

[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
