logging number of deleted messages
by David Mehler 06 May '17

06 May '17

Hello, I'm running Dovecot 2.29. I've got it going through a Mysql database. I've got the auto expunge plugin loaded. What I'm wanting to know is is there message count deletion ability? For example, does the mail_log, trash, or auto expunge plugins log how many messages were deleted? Thanks. Dave.

IMAP-auth on LAN and otherwise
by Rupert Gallagher 03 May '17

03 May '17

Hello, Thunderbird has been bugging us with connection errors. Dovecot is installed on a local server that carries a local IP and a public IP. When Thunderbird on a local client connects successfully, Wireshark shows a SYN request from the client's IP on LAN to the public IP of the server, followed by the ACK from the same public IP. When Thunderbird on the same local client fails to connect, Wireshark shows a SYN request from the client's IP on LAN to the public IP of the server, followed by the ACK from the server's LAN address, the client does not accept the ACK as valid and sends a new SYN request. The loop eventually leads to time-out. At the client's console, the DNS query of the IMAP server always responds with the server's public IP address. It is evident from Wireshark that the dovecot server sends ACKs from two IPs. Is it possible to instruct Dovecot to use the public IP only?

Problem with Userid

I have a problem with a physical user that was removed and recreated whith same name and different uid. The home dir, the mailbox file and the index directory where removed and recreated with the new uid/gid. I can feed the mailbox via procmail, though dovecot-lda complains that userids do not match: May 02 15:27:33 lda(alessandro_cmr): Error: stat(/var/spool/mailboxes/alessandro_cmr/INBOX) failed: Permission denied (euid=3525(alessandro_cmr) egid=111(poppers) missing +x perm: /var/spool/mailboxes/alessandro_cmr, dir owned by 1000:111 mode=0700) doveadm auth cache flush says 28 entries flushed but the situation does'nt change. here's my doveconf -n: # 2.2.29.1 (e0b76e3): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.17 (e179378) # OS: Linux 3.0.101-105-pae i686 openSUSE 11.4 (i586) ext3 auth_cache_size = 3 k auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes default_client_limit = 1249 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 = </etc/ssl/ca.crt ssl_cert = </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 = mostmaster(a)mcs.it } Any idea?

Sieve dict and bindir question
by Alessio Cecchi 03 May '17

03 May '17

Hi, I have setup the latest Dovecot and Sieve with dict in order to read rules from MySQL and works fine: sieve_before = dict:proxy::sieve;name=activesql;bindir=~/.sieve-bin dict { sieve = mysql:/etc/dovecot/dovecot-dict-sieve-sql.conf.ext } # cat /etc/dovecot/dovecot-dict-sieve-sql.conf.ext connect = host=10.1.1.1 dbname=dovecot user=dovecot password=Ciao map { pattern = priv/sieve/name/$script_name table = user_sieve_scripts username_field = username value_field = id fields { script_name = $script_name } } map { pattern = priv/sieve/data/$id table = user_sieve_scripts username_field = username value_field = script_data fields { id = $id } } But when I update the rules in mysql sieve continue to apply only the "old" rules stored in the binary. The only way to apply the new rules is to delete the .sieve-bin/activesql.svbin. If I remove ";bindir=~/.sieve-bin" works fine. This is a cache issue and can be fixed via setting, is an issue or is a "feature" :-) ? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

dovecot log shows: service=imap ... Error: Temp file creation to /tmp/dovecot.imap. failed: No such directory
by Peter Kielbasiewicz 03 May '17

03 May '17

I am using dovecot 2.2 with plesk 12 and I have made no modifications to the dovecot config. Logwatch reports the messages below. The errors don't seem to appear for every imap connect as can be seen from the number of deliveries and successful logins. So what makes dovecot fail sometimes to create the /tmp/dovecot.imap? Dovecot Deliveries: 19 Dovecot IMAP and POP3 Successful Logins: 106 Dovecot disconnects: 72 **Unmatched Entries** dovecot: message repeated 4 times: [ service=imap, user=tester(a)example.com, ip=[::1].

Hi, I am trying to configure Pigeonhole to get filters in RoundCube working. Unfortunately I am getting following error in DoveCot log instead: May 01 14:35:41 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=248(<getpwuid() error>) egid=248(<getgrgid() error>) missing +x perm: /, we're not in group 202, dir owned by 0:202 mode=0750) May 01 14:35:41 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=248(<unknown>) egid=248(<unknown>) missing +x perm: /, we're not in group 202, dir owned by 0:202 mode=0750) May 01 14:36:00 master: Warning: Killed with signal 15 (by pid=37695 uid=0 code=kill) May 01 14:36:36 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=248(<getpwuid() error>) egid=248(<getgrgid() error>) missing +x perm: /, we're not in group 202, dir owned by 0:202 mode=0750) May 01 14:36:36 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=248(<unknown>) egid=248(<unknown>) missing +x perm: /, we're not in group 202, dir owned by 0:202 mode=0750) May 01 15:17:08 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=248(<getpwuid() error>) egid=248(<getgrgid() error>) missing +x perm: /, we're not in group 202, dir owned by 0:202 mode=0750) May 01 15:17:08 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=248(<unknown>) egid=248(<unknown>) missing +x perm: /, we're not in group 202, dir owned by 0:202 mode=0750) Above appears in log, when I am trying to access filters configuration in RC or manually connecting to sieve using telnet.

Re: Re: migrate Maildir to mdbox
by Joseph Tam 02 May '17

02 May '17

Michael Segel <dovecot_mjs(a)hotmail.com> writes: > Which is preferred? MailDir or Mbox? (directory vs flat file) Mailbox; I wish I converted when I had the chance. The only benefits I can see with mbox is that it's slightly less complicated, and if you're doing pattern searching or some global mailbox operation, less I/O intensive, but that's a niche case and usually ameliorated by indices. However, backing up mbox is a pain since changes results in the entire file being backed up for snapshotting filesystems, and atomicity of I/O operations is much harder. It just doesn't scale well for large mailboxes. As Aki recommends, use something other than mbox unless you got some legacy issue. > How would you do this when migrating from an old server to a new one? Lots of third party scripts out there that will convert for you. I think you can do dovecot->dovecot dsync to convert. Joseph Tam <jtam.home(a)gmail.com>
