[Dovecot] different locations for different reals
by Arne Van Theemsche 24 Jun '06

24 Jun '06

Hi I've been reading a lot, but I think I'am confused about namespaces. We are planning a migration of our pshychical mail storage. This will mean that subfolders are moving from /home to /var/spool/mail. I was thinking, for the migrations of creating a realm. I would like that if a user logs in with his username, the old location is used, if the user logs in with username@REALM, the subfolders are to be searched in the new location, is this possible? Can I use a different mail location per realm? thx in advance Arne

[Dovecot] Large mbox files.
by Kevin Warren 24 Jun '06

24 Jun '06

I'm very sorry if this is a faq. I've spent considerable time reading documentation and doing Google searches to no avail...and the mailing list archive isn't searchable as far as I can tell. Anyway, the question: When I try to open a large mbox file from Squirrel Mail I receive the following Dovecot error: Jun 23 10:47:55 jetta dovecot: [ID 107833 mail.error] IMAP(kevin): file mbox-sync-rewrite.c: line 400 (mbox_sync_read_and_move): ass ertion failed: (need_space == (uoff_t)-mails[idx].space) Jun 23 10:47:56 jetta dovecot: [ID 684838 mail.error] child 28535 (imap) killed with signal 6 Not sure what other information you will need. (There's no posting guideline for the mailing list) Here's my guess: Dovecot version: 1.0.beta9 OS version: Solaris x86 v10 I'm guessing a listing of non-default values in dovecot.conf would be useful too: $ grep -vE "^ *#" dovecot.conf | grep -E "^ *[a-z\}]" ssl_listen = *:993 first_valid_uid = 100 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } plugin { }

[Dovecot] dovecot and thunderbird
by Mark Davies 24 Jun '06

24 Jun '06

We've been using dovecot for a while now (currently 1.0beta7) and it works nicely. We have just one reoccuring problem: When using thunderbird as the imap client sometimes when messages are moved from the inbox to other folders (including Trash) they shortly thereafter reappear in the inbox - this can happen multiple times to the same message. We have multiple namespaces set up so that inbox is mbox format in ~/.poffice/username and other folders are maildir in ~/Maildir - both of these are on NFS. Indexes are on local storage. The problem only seems to happen with thunderbird. kmail, mac mail, outlook, pine all work fine. If we effectively move a user so that their inbox is also maildir then the problem doesn't happen. The inbox being mbox format is for historic reasons and medium to long term this should change to maildir but in the interim can anyone see anything different that thunderbird does to other imap clients that might be tickling an underlying bug? cheers mark

[Dovecot] 2nd Question on v1.0 setup and maildir
by Patrick Carney 23 Jun '06

23 Jun '06

_____ From: Patrick Carney [mailto:patrick@castandcrew.com] Sent: Thursday, June 22, 2006 8:55 AM To: 'dovecot(a)dovecot.org' Subject: Question on v1.0 setup and maildir Hello all. I appreciate the responses to my problem on v0.99.14. Thank you all. We have built a new server running version 1.0-0_15.beta9.el4. The mail delivery agent is sendmail. We seem to have gotten it up fairly easily. But we have one problem. We are using the maildir feature instead of mbox and when ever mail gets delivered, it is not sending it to the \maildir\new folder. It seems to be dumping it in the root of the maildir directory, thus when a client checks for email, it appears nothing is there. Here is a sample from our config. Any suggestions will be much appreciated. Forgive me if this is elementary question, but I am new to dovecot. ## Mailbox locations and namespaces ## # Default MAIL environment to use when it's not set. By leaving this empty # dovecot tries to do some automatic detection as described in # doc/mail-storages.txt. There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See doc/variables.txt for full list. Some examples: # # default_mail_env = maildir:/var/mail/%1u/%u/Maildir # default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u # default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n # default_mail_env = maildir:/home/%u/Maildir # If you need to set multiple mailbox locations or want to change default # namespace settings, you can do it by defining namespace sections: # # You can have private, shared and public namespaces. The only difference # between them is how Dovecot announces them to client via NAMESPACE # extension. Shared namespaces are meant for user-owned mailboxes which are # shared to other users, while public namespaces are for more globally # accessible mailboxes. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. default_mail_env does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. #separator = / # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox. This is in same format as # default_mail_env, which is also the default for it. #location = # There can be only one INBOX, and this setting defines which namespace # has it. #inbox = yes # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension or shown in LIST replies. This is mostly useful when converting # from another server with different namespaces which you want to depricate # but still keep working. For example you can create hidden namespaces with # prefixes "~/mail/", "~%u/mail/" and "mail/". #hidden = yes #} # Grant access to these extra groups for mail processes. Typical use would be # to give "mail" group write access to /var/mail to be able to create dotlocks. #mail_extra_groups = # Allow full filesystem access to clients. There's no access checks other than # what the operating system does for the active UID/GID. It works with both # maildir and mboxes, allowing you to prefix mailboxes names with eg. /path/ # or ~user/. #mail_full_filesystem_access = no ##

[Dovecot] This store does not support subscriptions, or they are not enabled...
by Dan Stromberg 22 Jun '06

22 Jun '06

Hi folks. I'm using evolution 2.2.3 on Fedora Core 4 with simap to dovecot 1.0beta9. I had the same problem with dovecot 1.0alpha1. The problem is that I can't seem to subscribe to any folders. Nor can I seem to get this combination to list all of my folders. I'd be fine with either. It used to be, that if I just toggled "show only subscribed folders" a few times, I'd start getting folders, but not anymore. Of course, sometimes the behavior would be the opposite of what I'd selected, but I wasn't too worried about that. Any suggestions? Thanks!

[Dovecot] maildir++ Quotas - bizarre behavior.
by Apps Lists 22 Jun '06

22 Jun '06

Hi Timo et al. I've been trying to track down why Dovecot recalculations of maildirsize are so wildly different (lower) than what Maildrop comes up with. I think I've found some bizarre behavior in Dovecot -- this is in beta9 as well as CVS from yesterday. It appears Dovecot isn't looking at /Maildir/cur ... /Maildir/new and /Maildir/tmp. It is, however, looking at /Maildir/.Drafts, /Maildir/.Sent, and /Maildir/.Trash. None of these folders contain any messages, but Dovecot seems to count the existence of . and .. as message files. Worse, it's coming up with actual usage data for these empty (of messages) folders. Presumably it's counting the log and cache files. I've attached a diff to quota-maildir.c which will enable some verbose logging. Also attached is a ls -lR of the Maildir in question as well as the output of the aforementioned debugging. Please help. Steve

[Dovecot] problem with kqueue
by Alessandro de Manzano 21 Jun '06

21 Jun '06

Hello, I'm a new user of Dovecot (since 1.0b8) and I'ld report about a possible bug. Situation: Dovecot 1.0beta9 with kqueue support FreeBSD 6.1-Release x86 machine (IBM x206, P4 3.2 Ghz) local filesystem UFS2 This is an internal, experimental, mail server running Postfix and Dovecot configured with Maildirs e IMAP-only access. Clients are quite few, now, just because it's an experiment. However are near all Outlook Express 6. Running with dovecot 1.0 beta8 _without_ kqueue support for few weeks was fine, no problems at all. A couple of days ago I updated to beta9 (using FreeBSD's portupgrade tools) and in the _same_time_ I enabled the kqueue support. Since then I've seen about 3-4 of these in the log: (note that process traps apparently after reporting the unrecognized event) Jun 20 10:38:53 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:38:54 bigblue dovecot: IMAP(laura2): Disconnected in IDLE Jun 20 10:38:54 bigblue dovecot: IMAP(laura2): Unrecognized event: kevent {.ident = 1, .filter = 0xfffffffe, .flags = 0x0000, .fflags = 0x00000000, .data = 0x00008322} Jun 20 10:38:54 bigblue dovecot: IMAP(laura2): mode: 0x004x Jun 20 10:38:54 bigblue kernel: pid 18426 (imap), uid 1004: exited on signal 6 Jun 20 10:38:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:38:54 bigblue dovecot: child 18426 (imap) killed with signal 6 Jun 20 10:38:54 bigblue dovecot: IMAP(laura2): Disconnected Jun 20 10:38:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:38:54 bigblue dovecot: IMAP(laura2): Disconnected in IDLE Jun 20 10:38:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:39:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:39:54 bigblue dovecot: IMAP(laura2): Disconnected in IDLE Jun 20 10:39:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:39:54 bigblue dovecot: IMAP(laura2): Disconnected in IDLE Jun 20 10:39:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:39:54 bigblue dovecot: IMAP(laura2): Disconnected in IDLE Jun 20 10:39:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:39:54 bigblue dovecot: IMAP(laura2): Disconnected Jun 20 10:39:54 bigblue dovecot: imap-login: Login: user=<laura2>, method=PLAIN, rip=192.168.9.31, lip=192.168.9.68 Jun 20 10:39:54 bigblue dovecot: IMAP(laura2): Disconnected in IDLE Any ideas ? Any one else got these messages ? I'ld try recompiling beta9 without kqueue support, probably the issue would disappear, but IMHO is not the best way to "correct" things :) Many thanks in advance! -- Alessandro de Manzano System & Network Administrator Playstos - TIMA S.p.A.
