[Dovecot] More efficient Deleting of a whole folder (or Purging Trash)
by Daniel Watts 31 Jan '08

31 Jan '08

Hi, I've straced a few dovecot processes after hitting purge on a large Trash folder (35,000 messages). It looks like it is going through each message, one by one, and removing (unlinking) each one. Is there not a more efficient way to do this? If Dovecot knows the whole folder is being deleted (ie a Trash purge), could it do something clever with the filesystem to just remove the whole folder? Incidently, the command that initially deleted those 35k messages to Trash took about 1 hour to complete on my server and effectively locked my account out for all that time. There were also an awlful lot of these output from my strace: nanosleep({0, 131475000}, NULL) = 0 lstat("/home/virtual/xxx.com/home/admin/Maildir/.Folders.Porter/dovecot-uidlist.lock", {st_mode=S_IFREG|0600, st_size=0, ...}) = 0 Not sure if there's much one can do about speeding up deleting a lot of messages though. My webmail client has a 'delete all messages' button for each folder. If there was an efficient IMAP command for deleting a whole folder that would be useful in those circumstances. Interested to know if there is anything that can be improved. Thanks, Daniel Dovecot 1.0.9 XFS Filesystem Maildir Directories

[Dovecot] Convert MBOX
by Erin D. Hughes 31 Jan '08

To all, I am using dovecot --version 1.0.10 and trying to convert MBOXes to MailDir's with the end goal of creating one folder filled with users old MBOXes that when they log in for the first time will be converted to Mail Dir format. I tried this and it did not work and gave me this output; <snip> default_mail_env = maildir:%h/mail/ #convert_mail = mbox:%h/mail:INBOX=/usr/local/src/tmpmail/%u convert_mail = mbox:%h/mail/:INBOX=/usr/local/src/tmpmail/%u Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] pop3-login: Login: user=<x4500>, method=PLAIN, rip=192.168.30.192, lip=172.20.12.8 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Loading modules from directory: /usr/local/lib/dovecot/pop3 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Module loaded: /usr/local/lib/dovecot/pop3/lib20_convert_plugin.so Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Effective uid=3000, gid=3000 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/:INBOX=/usr/local/src/tmpmail/x4500 Jan 30 17:17:04 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, inbox=/usr/local/src/tmpmail/x4500 Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/:INBOX=/usr/local/src/tmpmail/x4500 Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, inbox=/usr/local/src/tmpmail/x4500 Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/ Jan 30 17:17:06 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, control=, inbox= Jan 30 17:17:07 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Mailbox conversion: Couldn't copy mailbox dovecot.index.log: BUG: Unknown internal error Jan 30 17:17:07 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Mailbox conversion: Couldn't copy mailbox dovecot.index: BUG: Unknown internal error Jan 30 17:17:08 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Mailbox conversion: Couldn't copy mailbox dovecot.index.cache: BUG: Unknown internal error Jan 30 17:17:11 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/ Jan 30 17:17:11 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, control=, inbox= </snip> This actually created the x4500-convert directory but did not populate it Then I tried this trying to get the mail dir created and populated. <snip> #convert_mail = mbox:%h/mail:INBOX=/usr/local/src/tmpmail/%u convert_mail = mbox:/usr/local/src/tmpmail/%u:INBOX=/var/mail/%u Jan 30 17:22:45 pop01.unix dovecot: [ID 673593 mail.info] Dovecot v1.0.10 starting up Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] pop3-login: Login: user=<x4500>, method=PLAIN, rip=192.168.30.192, lip=172.20.12.8 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Loading modules from directory: /usr/local/lib/dovecot/pop3 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Module loaded: /usr/local/lib/dovecot/pop3/lib20_convert_plugin.so Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): Effective uid=3000, gid=3000 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/usr/local/src/tmpmail/x4500:INBOX=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/usr/local/src/tmpmail/x4500, index=/usr/local/src/tmpmail/x4500, inbox=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: data=/usr/local/src/tmpmail/x4500:INBOX=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): mbox: root=/usr/local/src/tmpmail/x4500, index=/usr/local/src/tmpmail/x4500, inbox=/var/mail/x4500 Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: data=/export/x4500/mail/jp/n/e/jorgen/x4500/mail/ Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.info] POP3(x4500): maildir: root=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, index=/export/x4500/mail/jp/n/e/jorgen/x4500/mail, control=, inbox= Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): mkdir_parents(/usr/local/src/tmpmail/x4500/.imap/INBOX) failed: Not a directory Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): open() failed with subscription file /usr/local/src/tmpmail/x4500/.subscriptions: Not a directory Jan 30 17:22:59 pop01.unix dovecot: [ID 107833 mail.error] POP3(x4500): Sending log messages too fast, throttling..

Can some one please help w/this? Additionally is there a way to run mail_convert on the command line to try to sort out the arguments? I noticed the converts are .so and .a in /usr/local/lib/dovecot/ so I doubt it but it can not hurt to ask.

[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
