[Dovecot] deliver + quota
by Manuel Mausz 03 Nov '10

03 Nov '10

Hi list, can someone please explain me the following behaviour of deliver in combination with fs-quota and reading from stdin: > # repquota -a | grep ud_3p5 > ud_3p5 -- 4464 10240 12288 10 0 0 > # stat -c "%s" /tmp/mymail > 4524853 so there's enough space for this mail > # su ud_3p5 -s/bin/sh -c "cat /tmp/mymail | /usr/libexec/dovecot/deliver -e; echo \$?" > sda6: warning, user block quota exceeded. > sda6: write failed, user block limit reached. > Not enough disk space > 77 vs. > # su ud_3p5 -s/bin/sh -c "/usr/libexec/dovecot/deliver -p /tmp/mymail -e; echo \$?" > 0 Must have something to do with create_raw_stream inside deliver.c System is running Dovecot v1.2.13 Thanks, / manuel

[Dovecot] Running 2.x in production
by Monika Janek 03 Nov '10

03 Nov '10

Hi! I'm setting up a new server and migrating from Cyrus to Dovecot. What would be the most stable version to install on a production system. Would 2.x be alright? I'm feeling lucky. System is Debian Lenny. Thanks for any information! Monika -- Monika Janek Systems Administrator, Side Effects Software Toronto, Ontario Canada 416-504-9876 x207 www.sidefx.com

[Dovecot] Know when a Folder is Expunged or Deleted
by Alex Baule 03 Nov '10

03 Nov '10

Hi Timo and Everyone.... There is a way to know when a folder it's been deleted ? And if this folder is empty ? Let's explain why... I intercept the expunge function, to treat my files expunged, but when i expunge a folder, this function it's not called, and my emails don't get my treatment to be expunged. Basically i need to do something like this: It's empty ? No --> return OK but Dont Delete folder, because it's not empty. Yes --> Return OK and Delete the Folder to be expunged. Tks !

[Dovecot] Virtual inbox folder bug
by Antonio Henrique Oliveira 03 Nov '10

03 Nov '10

Hi all, I've been using dovecot as our internal mail server for quite some time. It works very well. Each of our mailboxes have 1000+ messages (some have more than 4-5000 messages). I have recently started using virtual folders and, using an adaptation of an example script in the dovecot site (http://wiki.dovecot.org/Plugins/Virtual) to have a virtual folder changed to act as inbox. All of my email is delivered in some folder other than the real inbox via sieve scripts. My inbox is, therefore, a virtual folder, which only displays the unread emails on all the folders in the account. Everything works fine *except* that, when I mark an email as read or when I open an email directly on the inbox, it does not disappear from the inbox (as it should since it is not unread after being open or being marked as read). I'm not sure if this is a bug, a "feature", or a misconfiguration.... :) I'm using dovecot 1.2.13 on Debian Etch (installed using the backports repository). Attached is the file with the output of "dovecot -n", the script for the virtual folder and the custom login script to change the virtual folder to act as the inbox. I'm using Thunderbird 3.1.6 on Windows XP SP3 as the main mail client and also using an Android phone (Samsung Galaxy) to access the same account. Regards, -- Anto'nio Henrique A.

[Dovecot] Dovecot 1.1.20 on OS X - ACL deliver Problem
by R. Svejda 03 Nov '10

03 Nov '10

I am trying to create an archive postoffice by bcc all e-mail from the "real" mail server to an existing OS X server and by setting all ACL to read-only. Problem: deliver reports: "Fatal: mail_full_filesystem_access=yes is incompatible with ACLs" It seems, that the failure is independent of the existence of an ACL file. I cannot change machines (must be OS X) and I do not like to compile anything on that box (but I could re-configure stuff). Can anybody help how to get around this error with existing hard and software?

[Dovecot] Wrong protocol in socket (director-doveadm vs director) ?
by Edward Carraro 02 Nov '10

02 Nov '10

I just noticed this error in my logs: director: Error: doveadm not compatible with this server (mixed old and new binaries?) director: Error: director(10.161.192.28:541/right): Wrong protocol in socket (director-doveadm vs director) The first error I removed by changing director_doveadm_port = 541 to director_doveadm_port = 542 Not really sure why that fixed it. The second error I don't know how to clear. I found this thread, http://dovecot.org/pipermail/dovecot/2010-July/051022.html but it didn't work for me. If I create a new service for dovecot-doveadm service director-doveadm { inet_listener { port = 542 } } Then I get a new error saying: service(director-doveadm): executable is empty here is my original 10-director.conf file (i'm using dovecot 2.0.6) director_doveadm_port = 541 service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0666 } unix_listener director-userdb { mode = 0600 } inet_listener { port = 541 } } service imap-login { executable = imap-login director } service pop3-login { executable = pop3-login director } service managesieve-login { executable = managesieve-login director } protocol lmtp { auth_socket_path = /usr/local/var/run/dovecot/director-userdb passdb { driver = static args = proxy=y nopassword=y port=24 } }

[Dovecot] Dovecot 2.0.5 crash when It cannot remove maildir
by Len7hir 02 Nov '10

02 Nov '10

This is scenario that cause segmentation fault in my Dovecot. Maybe I do something wrong, but I don't know what... We run: mailbox_delete mailbox_delete do: mailbox_open(box) < 0 and after we have: box->v.delete(box) which run index_storage_mailbox_delete index_storage_mailbox_delete do: mailbox_close(box); and now mailbox is closed (this close box->view and mailbox open) Try to delete folder, but can't do this... example becaus it is system folder, or NFS failure... set error message and return -1. Now we are returning to mailbox_delete. And we have: if (ret < 0 && box->marked_deleted) and this is true mailbox_mark_index_deleted(box, FALSE) if (box->marked_deleted && del) this is false mail_index_transaction_begin(box->view, trans_flags); mail_index_view_ref(view) and segmentation fault, because view is 0x0 #0 mail_index_view_transaction_ref (view=0x0) at mail-index-view.c:81 #1 0xb7ef3214 in mail_index_transaction_begin (view=0x0, flags=MAIL_INDEX_TRANSACTION_FLAG_EXTERNAL) at mail-index-transaction.c:268 #2 0xb7eb7a73 in mailbox_mark_index_deleted (box=0x80c8268, del=false) at mail-storage.c:682 #3 0xb7eb80a9 in mailbox_delete (box=0x80c8268) at mail-storage.c:757 #4 0x0805001f in cmd_delete (cmd=0x8095978) at cmd-delete.c:46 #5 0x0805625c in client_command_input (cmd=0x8095978) at imap-client.c:741 #6 0x0805630b in client_command_input (cmd=0x8095978) at imap-client.c:791 #7 0x0805646d in client_handle_input (client=0x8095390) at imap-client.c:857 #8 0x08056f1f in client_input (client=0x8095390) at imap-client.c:908 #9 0xb7e6f110 in io_loop_handler_run (ioloop=0x806c370) at ioloop-epoll.c:212 #10 0xb7e6da98 in io_loop_run (ioloop=0x806c370) at ioloop.c:350 #11 0xb7e5b26a in master_service_run (service=0x806c2c0, callback=0x805f800 <client_connected>) at master-service.c:496 #12 0x0805f6da in main (argc=1752462689, argv=0x73616d2d) at main.c:358 This is Dovecot error or I do something wrong? -- Len7hir
