Strange thing on log rotation front
by Luciano Mannucci 22 Jan '18

22 Jan '18

Hi all! I've decided to rotate the dovecot logs automatically on my freebsd 10.4 server using the system's newsyslog feature. I started with logfile.info putting the line /var/log/dovecot/logfile.info 600 31 * @T16 ZCU /var/run/dovecot/master.pid 30 which should send a SIGUSER to the master process, which it seems to do for I see in the log file: master: Warning: Sent SIGKILL to 1 log processes master: Warning: Killed with signal 15 (by pid=69871 uid=0 code=kill) though the log process doesn't die. What did I do wrong? my doveconf -n says: root@baobab:/var/log/dovecot # doveconf -n # 2.2.28 (bed8434): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.17 (e179378) # OS: FreeBSD 10.4-RELEASE-p3 amd64 ufs auth_cache_size = 3 k auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes default_client_limit = 1228 default_vsz_limit = 712 M disable_plaintext_auth = no first_valid_gid = 0 first_valid_uid = 100 info_log_path = /var/log/dovecot/logfile.info listen = * log_path = /var/log/dovecot/logfile login_greeting = Dovecot at Baobab ready. login_trusted_networks = 127.0.0.0/8 212.45.144.0/24 192.168.134.0/24 mail_location = mbox:/var/spool/mailboxes/%u:INBOX=/var/spool/mail/%u:DIRNAME=mbox:INDEX=/var/dovecot_indexes/%u maildir_copy_with_hardlinks = no managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext mbox_lock_timeout = 443 secs namespace { inbox = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } protocols = pop3 imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imaps { address = * } process_limit = 512 } service pop3-login { chroot = executable = pop3-login -D inet_listener pop3s { address = * } process_limit = 512 } ssl_ca = </usr/local/etc/ssl/ca.crt ssl_cert = </usr/local/etc/ssl/certs/dovecot.pem ssl_key = # hidden, use -P to show it userdb { driver = passwd } version_ignore = yes protocol imap { imap_client_workarounds = delay-newmail mail_plugins = mail_log notify } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = yes } protocol lda { info_log_path = /var/log/dovecot/lda.log log_path = /var/log/dovecot/lda-errors.log postmaster_address = postmaxxxster(a)mcs.it } Luciano. -- /"\ /Via A.

How does this manifests itself: the client gets an inconsistent view of the outgoing mailbox that depends on which mailbox the client is using, or the optimization is broken and dovecot keeps having to (re)read the mailbox to acquire the IMAP STATUS?

Hello Florent, How did you proceed with the upgrade? Did you follow the recommended steps guide to upgrade ceph? (mons first, then OSDs, then MDS) Did you interrupt dovecot before upgrading the MDS specially? Did you remount the filesystem? Did you upgrade the ceph client too? Give people the complete scene and someone might be able to help you. Ask on ceph-users list too.

Fatal: nfs flush requires mail_fsync=always

Hiya all, I'm seeing this "Fatal: nfs flush requires mail_fsync=always" error on my testbed. The issue is that from what I can see, mail_fsync is set to always : # doveconf -n | grep mail_fs mail_fsync = always The result is that the client does not connect at all, which is not really what I wanted to happen :) Any idea what is going wrong here?

Replication configuration
by Mantas Gegužis 17 Jan '18

17 Jan '18

Hello, I am trying to configure replication between two servers, for only specified virtual users, without success of course :) I am using LDAP for accounting. I have tried to pass a file with list like this: replication_dsync_parameters = -d -N -l 30 -U -F /etc/dovecot/list I have even tried to specify users with LDAP filter: iterate_filter = (|(uid=user1)(uid=user2)) both without success... But replicator every 5 minutes tries to replicate all users. I want this mainly for testing (i am preparing to server migration) and for bigger control who and when will be replicated/transferred.

nfs flush requires mail_fsync=always

16 Jan '18

Hiya, I'm getting nfs flush requires mail_fsync=always rather consistently from my servers. As you can see below this has been enabled already - So what else am I missing?

I get about a half dozen rejection messages from various servers when I post to this list. Is there something I need to configure differently in my DMARC record to be better compliant? Daniel
