[Dovecot] 1.1b1 initial pop3 login: assertion failed
by David Jonas 01 Oct '07

01 Oct '07

Currently running 1.0.2 with 1.1b1 listening on a different port. On first pop3 login on 1.1b1 I received an immediate disconnect (I was testing with telnet) with the log entries below. Subsequent logins work fine. Other accounts that I tried did not have the same problem. So this is probably isolated to some bad indexes or something, but I thought I should let Timo know. Regards, David Here is what I found in the logs: ----------------------------------------- Sep 28 15:51:14 kelly-a dovecot: POP3(xxx(a)xxxxx.com)[8112]: Fixed index file /home/vmail/x/xxxxx.com/xxx/Maildir/dovecot.index: first_recent_uid 0 -> 1 Sep 28 15:51:14 kelly-a dovecot: POP3(xxx(a)xxxxx.com)[8112]: file mail-index-view-sync.c: line 304 (mail_index_view_sync_begin): assertion failed: (view->index->map->hdr.messages_count >= ctx->finish_min_msg_count) Sep 28 15:51:14 kelly-a dovecot: POP3(xxx(a)xxxxx.com)[8112]: Raw backtrace: pop3 [0x80cd42e] -> pop3(i_fatal+0) [0x80cce93] -> pop3(mail_index_view_sync_begin+0x228) [0x80a91d2] -> pop3(index_mailbox_sync_init+0xac) [0x8093abe] -> pop3(maildir_storage_sync_init+0x11e) [0x80646a1] -> pop3(mailbox_sync_init+0x1b) [0x80bb428] -> pop3(mailbox_sync+0x18) [0x80bb49b] -> pop3 [0x80582f5] -> pop3(client_create+0x237) [0x80587ac] -> pop3 [0x805afe8] -> pop3(main+0x95) [0x805b0e4] -> /lib/tls/libc.so.6(__libc_start_main+0xd3) [0x477de3] -> pop3 [0x80581ed] Sep 28 15:51:14 kelly-a dovecot: child 8112 (pop3) killed with signal 6 Other information ------------------------ $ cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 5) $ uname -r 2.6.9-42.0.10.ELsmp $ ./dovecot -n # 1.1.beta1: /usr/local/dovecot-1.1/etc/dovecot.conf base_dir: /var/run/dovecot-1.1/ protocols: imap pop3 listen(default): *:9143 listen(imap): *:9143 listen(pop3): *:9110 ssl_disable: yes login_dir: /var/run/dovecot-1.1/login login_executable(default): /usr/local/dovecot-1.1/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot-1.1/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot-1.1/libexec/dovecot/pop3-login login_greeting: postoffice.no-ip.com (1.1) login_log_format_elements: user=<%u@%d> method=%m rip=%r lip=%l %c login_process_per_connection: no verbose_proctitle: yes first_valid_uid: 89 mail_uid: vmail mail_gid: vmail mail_executable(default): /usr/local/dovecot-1.1/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot-1.1/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot-1.1/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/dovecot-1.1/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot-1.1/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot-1.1/lib/dovecot/pop3 mail_log_prefix: %Us(%u)[%p]: pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %f pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 user: nobody username_translation: %@ username_format: %Lu verbose: yes passdb: driver: sql args: /usr/local/dovecot-1.1/etc/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot-1.1/auth-client mode: 432 plugin: quota: dict:user::proxy::quota dict: quota: mysql:/usr/local/dovecot-1.1/etc/dovecot-dict-quota.conf

[Dovecot] ACL question
by Cory Coager 01 Oct '07

01 Oct '07

Does ACL's apply to all subfolders? For instance, if I create a dovecot-acl in a Maildir/, does it apply only to the INBOX or does it apply to all subfolders as well?

If I have a sieve script that use the vacation, deliver crashes. I think it could be a bug of the new (1.1) version of sieve language. Any help? Stefano.

[Dovecot] v1.1.beta2 - maildir quota calculation problem
by Andrew Pavlenko 01 Oct '07

01 Oct '07

I have a problem with the maildir quota plugin. Any imap operations cause the plugin to recalculate the mailbox size and put the new value in the second line of the maildirsize file, while the third line always contains the size of the latest operation. So the resulting sum is incorrect. Moreover, quota-warning is not working either. Have anybody else met such problem? mail# ./dovecot -n # 1.1.beta2: /usr/local/etc/dovecot.conf ... mail_plugins(default): quota mail_log mail_plugins(imap): quota mail_log mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 ... plugin: quota: maildir quota_rule: *:storage=10240 quota_warning: storage=75%% /usr/local/etc/quota-warning.sh 75

[Dovecot] Mixed Courier POP3 and Dovecot IMAP environment
by Jan van den Berg 01 Oct '07

01 Oct '07

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be able to use Dovecot IMAP: - I have to use the namespace prefix in the dovecot.conf file: I read this in the wiki. - "Patch" the source so Dovecot IMAP will look for/use 'courierimapuiddb' instead of 'dovecot-uidlist': otherwise I guess POP3 and IMAP users will have different UID files, right? Is this smart or will this still break the UID file? - "Patch" the source so Dovecot IMAP will look for/use 'courierimapsubscribed' instead of 'subscriptions' of should I just go with the renaming of the files? I'm thinking about patching so the transition can be as transparent as possible: Also if anything might go wrong in production I want to be able to switch back to the 'old' Courier IMAP (without renaming files etc.) Any thoughts on this? Cheers, Jan

[Dovecot] Released v1.1.beta2
by Timo Sirainen 01 Oct '07

01 Oct '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta2.tar.gz.sig Several bug/crashfixes. deliver now supports -a parameter (see http://wiki.dovecot.org/LDA) which allows Sieve plugin v1.1.2 to use envelope :detail "to" checks. I also did one more API change for mailbox_transaction_commit*(). There's probably something still wrong with SORT command, but other than that I've fixed everything that's been reported.
