Panic when runing "doveadm mailbox status ... vsize"
by Mark Costlow 20 Jul '16

20 Jul '16

I'm using dovecot 2.2.24 on FreeBSD 10.3. I'm working on converting users from maildir to mdbox, for the usual reasons. I have converted some test users and they generally work fine. But when I run "doveadm mailbox status" I get a Panic if I ask for the vsize field (or "all"), but other fields work fine. For example: # doveadm mailbox status -u bubbacheex3 "messages" INBOX INBOX messages=53 # doveadm mailbox status -u bubbacheex3 "guid" INBOX INBOX guid=bf976912f3748957761d0100f906a3d0 # doveadm mailbox status -u bubbacheex3 "unseen" INBOX INBOX unseen=52 # doveadm mailbox status -u bubbacheex3 "vsize" INBOX doveadm(bubbacheex3): Panic: file file-lock.c: line 269: unreached Abort trap I've only converted a few users, but they all exhibit this problem. I converted them with: dsync -u bubbacheex3 mirror maildir:/var/tmp/bubbacheex3 I have done a force-resync, which succeeds but doesn't change the behavior. I spent a little time trying to get gdb running but didn't get very far (couldn't seem to get it to find the source files once I got a few levels deep in the call stack). Before I beat my head on the gdb issue more, I thought I'd check here to see if anyone has any ideas. I didn't turn up anything in google or searching this list. Here's my "doveconf -n" output: ------------------------------------------------------ # 2.2.24 (a82c823): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.3-RELEASE-p3 amd64 ufs auth_failure_delay = 1 secs auth_mechanisms = plain login auth_winbind_helper_path = /usr/local/bin/ntlm_auth auth_worker_max_count = 60 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 100 first_valid_uid = 1000 listen = * login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_location = mdbox:/var/mail/%u:INDEX=/var/dovecot/%u mail_log_prefix = "%Us(%u): " mail_nfs_storage = yes mail_privileged_group = mail mdbox_rotate_interval = 1 days mdbox_rotate_size = 4 M mmap_disable = yes namespace { inbox = yes location = prefix = separator = . } passdb { args = session=yes dovecot driver = pam } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { mode = 0600 } user = root vsz_limit = 256 M } service imap-login { chroot = login process_limit = 128 process_min_avail = 10 service_count = 1 user = dovecot vsz_limit = 64 M } service imap { drop_priv_before_exec = no process_limit = 512 vsz_limit = 256 M } service pop3-login { chroot = login process_limit = 128 process_min_avail = 5 service_count = 1 user = dovecot vsz_limit = 64 M } service pop3 { drop_priv_before_exec = no process_limit = 512 vsz_limit = 256 M } ssl_cert = </etc/mail/certs/mail.swcp.com.pem ssl_cipher_list = ALL:!LOW:!SSLv2 ssl_key = </etc/mail/certs/mail.swcp.com.pem userdb { args = blocking=yes driver = passwd } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_max_userip_connections = 20 mail_plugin_dir = /usr/local/lib/dovecot/imap } protocol pop3 { mail_max_userip_connections = 10 mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = no pop3_lock_session = no pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_no_flag_updates = no pop3_reuse_xuidl = yes pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ mail_plugin_dir = /usr/local/lib/dovecot/lda postmaster_address = postmaster(a)swcp.com quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r sendmail_path = /usr/sbin/sendmail } ------------------------------------------------------ Thanks, Mark -- Mark Costlow | Southwest Cyberport | Fax: +1-505-232-7975 cheeks(a)swcp.com | Web: www.swcp.com | Voice: +1-505-232-7992 Mail Minder - Intelligent Push Notifications for Email on the iPhone http://mailminderapp.com/download or in the App Store

Virtual mailboxes
by Lefteris Tsintjelis 19 Jul '16

19 Jul '16

I have been banging my head to the walls for the past couple of days to make virtual mailboxes work and I finally found the problem. It seems when prefetch is used the user_query is not working at all. However, I have not found any reference to this one. http://wiki.dovecot.org/Plugins/Virtual I have tried to add the SQL statements to the password_query with prefetch but it did not work. It seems that it only works with prefetch off.

dovecot --version tarball
by Leon Kyneur 19 Jul '16

19 Jul '16

Hi, Trying to understand what the version numbers mean. I typically build from the stable tarball and then apply patches as needed.. however since 2.2.25 this hasn't been working (not sure if it worked before or never really looked closely TBH). http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz - shows GITID 7be1766 however it has commits / changes newer than this. Also the github tag for 2.2.25 is c1527e5 which doesn't match the source tarball as well. Should the source tarball and git commit hash be related? Thanks Leon

Some killed with signal 11 after upgrade to 2.2.25

Hi, after to upgrade to dovecot-2.2.25 I see some killed with signal 11 in the log file: Jul 18 08:41:59 pop01 dovecot: pop3(rossi(a)milano.it): Fatal: master: service(pop3): child 32318 killed with signal 11 (core dumped) Jul 18 09:22:48 pop01 dovecot: imap(mail_backup(a)domain.it): Fatal: master: service(imap): child 16137 killed with signal 11 (core dumped) I’m not sure but I think happens with new users at the first login but I’m not able to reproduce it.

Include IMAP Junk folder to pop3 clients.

Moving Maildir folders
by Mark Foley 18 Jul '16

18 Jul '16

Our office had a user leave. Another user is taking over her duties and needs reference to the departing user's email. I've copied that entire departed user's Maildir structure to the current user: mv olduser/Maildir/.* curuser/Maildir/.olduser I did change permission and ownership on curuser/Maildir/.olduser to be the target user. I did not bring over the olduser/Maildir/dovecot* files (indexes, subscriptions, etc.) as I thought that would be bad. Nevertheless, the curuser cannot see this new olduser folder (which should be at the same level as Inbox, Junk Mail, etc.). I did manually add olduser to the curuser/Maildir/subscriptions file, but still nothing. So, what did I do wrong and how do I fix it? THX -- Mark

doveconf -n display error for "remote"
by Michael Fox 15 Jul '16

15 Jul '16

Upon further testing, it seems that the issue below may only be a display bug in doveconf. In other words, the remote filter appears to work as configured, even though it is displayed with duplicate prefix length by doveconf. Is this sufficient information to report a bug or is there some other protocol? Michael ------------------------------------------- Dovecot --version: 2.2.9 I configured the following in local.conf: remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes } But, when I run doveconf -n, I see: remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no } Note the repeated network prefix length (/27/27 and /24/24).

controlling STARTTLS by IP address
by Michael Fox 15 Jul '16

15 Jul '16

On my POP3 server, I need to be able to control the use of STARTTLS by client IP address. Specifically: * Clients on certain internal subnets (e.g., 192.168.1.0/24) must not have the option to use TLS. If the client tries to use STARTTLS, the option should be rejected. This is to satisfy US FCC rules regarding the use of encryption over certain radio frequencies. * All other internal clients (e.g., 192.168.0.0/16, but not 192.168.1.0/24) should be able to use STARTTLS if they choose to. * All external clients (0.0.0.0/0) will be required to use TLS. Is there a way to control which clients are allowed to use STARTTLS according to the client's IP address? Thanks, Michael

authentication failed: Connection lost to authentication server
by Zhang Huangbin 15 Jul '16

15 Jul '16

Dear all, I got error "authentication failed: Connection lost to authentication server", i turned on debug mode in Postfix/Dovecot, but this is the error i can get. All other errors point to sasl auth failure, what does "connection lost to authentication server" means? How can i exactly know what the problem is and how to fix it? Here's my Dovecot/Postfix configuration, with Active Directory integration. - dovecot.conf: http://pastebin.com/7T05kvmH - dovecot-ldap.conf: http://pastebin.com/DtkAg01v - Postfix main.cf: http://pastebin.com/Z9Wihmvr Dovecot/Postfix and AD are running in the same network (192.168.10.X), no firewall between them. Thanks for your help. :)
