I've re-sent the message, this time to the list. It should arrive along with this.

[Dovecot] Virtual Alias Forwarding
by Eric Biondi 30 Jan '08

30 Jan '08

I'm having a problem with Dovecot and forwarding of aliases. Any help would be greatly appreciated. I'm using Postfix, Mysql, dovecot, amavis. mysql> SELECT * FROM alias; | address | goto | domain | created | modified | active | It seems from the logs that incoming mail is being delivered to the mailbox via dovecot. Mail gets to the correct mailbox (address field), however, if I change the destination mailbox (goto) in the alias table in mysql, the mail still goes to the main mailbox (address). mysql_virtual_alias_maps.cf looks to be configured correctly but I'm suspecting that dovecot is circumventing that file. I'll post maillog entry, dovecot-deliver.log entry, dovecot-mysql.conf, mysql_virtual_alias_maps.cf, and dovecot.conf below in case that helps. Thanks in advance for anything that helps me resolve this.

[Dovecot] sa learning from an imap spam folder
by Zbigniew Szalbot 29 Jan '08

29 Jan '08

Hello, I am sorry if I am writing to a wrong list because honestly I do not know where to write but I would like to be able to set up sa-learn via cron to learn from spam folder of a particular email account (via IMAP). Can anyone share how to do it? Is dovecot involved in it? I am using: Exim 4.69 Dovecot 1.0.10 p5-Mail-SpamAssassin-3.2.1 Thanks a lot for helping. Zbigniew Szalbot

[Dovecot] Load average on machine 400+
by Patrick 29 Jan '08

29 Jan '08

Hi all, Over the past week our mail server which NFS mounts the /home directory for mail has been experiencing major load issues. When doing a 'top', it appeared that slapd was the culprit (we use LDAP for authentication), but after upgrading the system and updating ldap, the cpu usage for LDAP has gone down, but the load average as not. I'm using Maildir. Everything from /home is NFS mounted, and the structure looks like this: /home/USERNAME/Maildir We're doing about 300 email messages a minute right now to that server, which isn't that much. I'm at a loss of words right now as I do not know where to troubleshoot from here. I've come up with the following questions: 1) I've noticed that some of our users have 500mb Maildir folders some even have 3gb+ - would this cause the CPU to have such a high load? 2) Currently on the box there is about 120 POP3 connections and 40 IMAP connections. Could this be the issue? 3) When I first set up this server, I appended INDEX=MEMORY to the end of the mail_location line. Should I remove this? I wanted to either remove it or put it on the local machine to speed things up. Here is my config: ##################### protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no log_path = /var/log/dovecot.log ssl_disable = no ssl_cert_file = /usr/share/ssl/xyz.com/xyz.com.crt ssl_key_file = /usr/share/ssl/xyz.com/xyz.com.key login_dir = /var/run/dovecot-login login_user = dovecot login_process_size = 64 login_process_per_connection = yes login_max_processes_count = 128 login_max_connections = 256 mail_location = maildir:/home/%u/Maildir:INDEX=MEMORY mmap_disable = yes fsync_disable = yes first_valid_uid = 200 maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = yes protocol imap { imap_client_workarounds = outlook-idle delay-newmail } protocol pop3 { pop3_no_flag_updates = no pop3_lock_session = no pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = } protocol lda { fsync_disable = no postmaster_address = postmaster(a)xyz.com hostname = mail.xyz.com } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_username_format = %Lu auth_verbose = yes auth_worker_max_count = 30 auth default { mechanisms = plain login passdb pam { args = blocking=yes } userdb passwd { } user = dovecot-auth socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } ##################### Again, this only happened within the past 1-2 weeks. How can I fix? Thanks in advance! Patrick

Re: [Dovecot] Dovecot/SeLinux issues after RHEL5.1 upgrade
by Ion Soltan 29 Jan '08

Thanks to Marius, I've got this problem fixed! I don't know how or why, but selinux directory contexts have been altered during the update for everyone else on the system except myself (what makes it odd is that my user has the same group and permissions as everyone else). So what did the trick was to apply: chcon -t user_home_dir_t to each user's home, mail, .imap and INBOX directories. Thanks again for pointing me in the right direction, Marius!

[Dovecot] Messages not moved from Inbox by Apple Mail (Dovecot 1.0.10)
by Tom Collins 29 Jan '08

29 Jan '08

I just upgraded a server from Courier-IMAP to Dovecot, and I'm seeing some odd behavior. It's probably the result of something I did wrong in my configuration, and I'm hoping someone will let me know the easy fix for it. I have rules set up in Apple Mail to move and copy messages to different folders, some of which are IMAP folders, others on my own system. With Courier-IMAP, the messages would get moved without a problem. With dovecot, that's not happening. Here's my dovecot config. I've tried changing maildir_copy_with_hardlinks and maildir_copy_preserve_filename to "no", but that didn't seem to help. # 1.0.10: /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes namespace: type: private prefix: INBOX. inbox: yes auth default: mechanisms: plain login digest-md5 cram-md5 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% username_translation: %@ passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir I haven't tried logging the IMAP session yet, but I can turn off SSL, fire up Wireshark and monitor the session if necessary. Is this a known problem? I'm able to move messages between folders manually, but when Apple Mail moves the new messages it doesn't work. -- Tom Collins - tom(a)tomlogic.com Vpopmail - virtual domains for qmail: http://vpopmail.sf.net/ QmailAdmin - web interface for Vpopmail: http://qmailadmin.sf.net/

[Dovecot] Dovecot/SeLinux issues after RHEL5.1 upgrade
by Ion Soltan 28 Jan '08

28 Jan '08

Hello to everyone on the list, I have upgraded my RHEL4 to RHEL5.1 yesterday (all updates have been applied to it as well). I used to have dovecot v0.99.11 on the old system. Everything was working fine. Now I have 5.1 and its respective dovecot v1.0.rc15. Upon upgrading to RHEL5.1, dovecot no longer works correctly. The first thing I did after rewriting the config file for the updated version, was to check my own email. It works fine. However, no other user on the system can check his/hers. Here is what the log shows for everyone except myself: ============================ Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): open() failed with file /home/jj/mail/.imap/INBOX/dovecot.index.log: Permission denied Jan 27 13:56:41 warp dovecot: POP3(jj): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-01-27 13:56:41] ============================ There are NO complaints reported by selinux in the logs. If I setenforce 0 (disable selinux), everything is working fine for everyone. If I disable selinux monitoring on dovecot (setsebool dovecot_disable_trans 1), nothing changes, which makes me think that something else is causing the problem. I do very much want to use selinux, however, I cannot figure out what the problem is and I have been trying for many hours. Can anyone help? Thanks, Ion

[Dovecot] dovecot servers hanging with fuse/glusterfs errors

hi. i've got a clustered mail system with glusterfs and some postfix, squirrelmail and dovecot machines sharing the same storage system through glusterfs. each server has only postfix or squirrel or dovecot installed on it. The thing is... dovecot servers hang very often and the last thing they always log is this: ************* login: Unable to handle kernel paging request at 0000000000100108 RIP: [<ffffffff88020838>] :fuse:request_end+0x45/0x109 PGD 1f729067 PUD 1faae067 PMD 0 Oops: 0002 [1] SMP CPU 0 Modules linked in: ipv6 fuse dm_snapshot dm_mirror dm_mod Pid: 678, comm: glusterfs Not tainted 2.6.18-xen #1 RIP: e030:[<ffffffff88020838>] [<ffffffff88020838>] :fuse:request_end+0x45/0x109 RSP: e02b:ffff88001f04dd68 EFLAGS: 00010246 RAX: 0000000000200200 RBX: ffff88001db9fa58 RCX: ffff88001db9fa68 RDX: 0000000000100100 RSI: ffff88001db9fa58 RDI: ffff88001f676400 RBP: ffff88001f676400 R08: 00000000204abb00 R09: ffff88001db9fb58 R10: 0000000000000008 R11: ffff88001f04dcf0 R12: 0000000000000000 R13: ffff88001db9fa90 R14: ffff88001f04ddf8 R15: 0000000000000001 FS: 00002b29187c53b0(0000) GS:ffffffff804cd000(0000) knlGS:0000000000000000 CS: e033 DS: 0000 ES: 0000 Process glusterfs (pid: 678, threadinfo ffff88001f04c000, task ffff88001fc5a860) Stack: ffff88001db9fa58 ffff88001f676400 00000000fffffffe ffffffff88021056 ffff88001f04def8 000000301f04de88 ffffffff8020dd40 ffff88001f04ddb8 ffffffff80225ca3 ffff88001de23500 ffffffff803ef023 ffff88001f04de98 Call Trace: [<ffffffff88021056>] :fuse:fuse_dev_readv+0x385/0x435 [<ffffffff8020dd40>] monotonic_clock+0x35/0x7d [<ffffffff80225ca3>] deactivate_task+0x1d/0x28 [<ffffffff803ef023>] thread_return+0x0/0x120 [<ffffffff802801d3>] do_readv_writev+0x271/0x294 [<ffffffff802274c7>] default_wake_function+0x0/0xe [<ffffffff803f0976>] __down_read+0x12/0xec [<ffffffff88021120>] :fuse:fuse_dev_read+0x1a/0x1f [<ffffffff802804bc>] vfs_read+0xcb/0x171 [<ffffffff802274c7>] default_wake_function+0x0/0xe [<ffffffff8028089b>] sys_read+0x45/0x6e [<ffffffff8020a436>] system_call+0x86/0x8b [<ffffffff8020a3b0>] system_call+0x0/0x8b Code: 48 89 42 08 48 89 10 48 c7 41 08 00 02 20 00 f6 46 30 08 48 RIP [<ffffffff88020838>] :fuse:request_end+0x45/0x109 RSP <ffff88001f04dd68> CR2: 0000000000100108 dovecot01gluster01 kernel: Oops: 0002 [1] SMP dovecot01gluster01 kernel: CR2: 0000000000100108 <3>BUG: soft lockup detected on CPU#0!

The thing is all machines i've got have the very same version of glusterfs-client, but only the dovecot ones hang. Do you have any idea? Thank you.
