[Dovecot] replicator/dsync over tcp
by Michael Grimm 08 Apr '13

08 Apr '13

Hi -- I am testing replicator/dsync over tcp, and I did run into some issues. First of all I did need to extend http://wiki2.dovecot.org/Replication to get dsync over tcp running without ssl: | # dsync over tcp default port | # | doveadm_port = 12345 | service doveadm { | # running dsync over tcp and using ssl | # added-->| user = vmail | inet_listener { added-->| address = 1.2.3.4 | port = 12345 | # ssl = yes | } | } | plugin { | # this host replicates to remote host | # | mail_replica = tcp:SERVER-A.TLD That didn't work ... | dovecot: doveadm(test): Error: doveadm_password not set, can't authenticate to remote server ... thus, I needed to add: added-->| local 1.2.3.4 { added-->| # password for client authentication by doveadm server added-->| # added-->| doveadm_password = secret added-->| # allow client to only use specified list of commands (default is all): added-->| # added-->| #doveadm_allowed_commands = added-->| } 1. Question: may one include "secret" from a file? Well, that runs like a charm! Now, I did try to add ssl by activating "ssl = yes" in 'service doveadm' (see above) and adding ... | # used by replicator/dsync over tcp | # | ssl_client_ca_dir = /<path-to>/ssl/certs ... and ... | mail_replica = tcps:SERVER-A.TLD But, this didn't work (logfile at remote server): | dovecot: doveadm(test): Invalid certificate: self signed certificate: /OU=dovecot server/CN=OTHER-NAME.TLD/emailAddress=postmaster(a)OTHER-NAME.TLD | dovecot: doveadm(test): Error: SERVER-A.TLD: Received invalid SSL certificate | dovecot: doveadm(test): Error: sync: Disconnected from remote The OTHER-NAME.TLD is served by my additional settings used by my MUAs: | ssl_cert = </<path-to>/ssl/certs/OTHER-NAME.TLD.pem | ssl_key = </<path-to>/ssl/private/OTHER-NAME.TLD.pem I did supply SERVER-A.TLD certs and private certificates at both servers as well, but dovecot seems to use those of OTHER-NAME.TLD for replicator/dsync instead :-( 2. Question: May I config the certificate that should be used for replicator/dsync and that might be different from those used by my MUAs (other then pointing to '/<path-to>/ssl/certs')? I am quite sure that I screwed my config somehow, but I cannot find the cause. Thus, someone? Thanks, and with kind regards, Michael

[Dovecot] Outlook 2013 - mounting folders with XLIST
by Hajo Locke 04 Apr '13

04 Apr '13

Hello, i do some tests with dovecot 2.1.7 and activated a default special-use config. To get it work with outlook 2013, i also added XLIST to imap capability string. basically this is working. is somebody also using special-use folders successful with outlook 2013? In my understanding of special-use extension, every client should map its own local folders to corresponding folders on server. Real Name of folder on server should be irrelevant, if a folder "aaa" is marked as \Sent, then a Client should show this folder as "Sent" "Sent Items" or "Gesendete Objekte", just like local preferences. Outlook 2013 seems to work slightly different. Outlook 2013 seems to really use the marked folder on server regardless of local preferences. If i mark Drafts as \Drafts, outlook 2013 will use this for drafts even in german environment. Did somebody other notice this behaviour? Is it possible to adjust some settings in outlook 2013 fo fix this? Otherwise the serveradmin is forced to provide special-use folders per every single user and let them choose how his folders should be named? What experience did others make who use special-use folders in productive environment? Thanks, Hajo

[Dovecot] Mongo backend for userdb and passdb
by Damien Churchill 03 Apr '13

03 Apr '13

Hi, I was wondering if any work had been made (out of tree) or has been planned for a mongo driver? If not is it something that would be of any interest for being included? Regards, Damien

[Dovecot] sieve-filter ignoring separator
by Isak Rubin 03 Apr '13

03 Apr '13

It seems like running sieve-filter from the console ignores the separator setting, thus not letting me filter into folder names containing dots. Normal delivery using lda handles it just fine, but not when using the sieve-filter command. Character not allowed in mailbox name: '.' Is there anyway to override this or is patching and recompiling the source my only option? # dovecot --version 2.1.9 /Isak

[Dovecot] Separate log file for Sieve
by Ewald Dieterich 03 Apr '13

03 Apr '13

I use log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log debug_log_path = /var/log/dovecot/debug.log to log to different files. Since I don't consider Sieve errors as severe as "real" Dovecot errors I would like to keep them away from the error log. Is it possible to configure a separate log file for Sieve?

[Dovecot] (no subject)
by Walter Steiner 02 Apr '13

02 Apr '13

I've run into a problem with `doveadm backup` (2.2 rc2 and 20130226) I did not notice in 2.1.15 doveadm backup [-Dv] -R -u cyrtest1(a)iai.uni-bonn.de -m INBOX imapc: => crashes (signal 6 with acl plugin configured, sig 11 without acl) If this is considered a bug (not just because of the crash but in the meaning of "my configuration should work") it would be great if it could be fixed.;-) If I can provide more detail (log, gdb bt full and doveconf -n follow the next paragraph) or test something I would be happy to to so. As I'm planning dsync replication of the two backends I thought it would be better to start things with the upcoming new dovecot 2.2 (dsync protocol) instead of 2.1.15. (?!) --- first some information about what I'm trying to do --- We want to replace our single cyrus 2.4 server with two backend servers (separate storage and all user mailboxes etc. each) Even if cyrus-to-cyrus should be much easier _and_ time is slipping away I want to take this one opportunity to switch to dovecot if possible. - Thank you very much for your great work on dovecot and all the efforts! - We want the IMAP clients to continue using their folders/messages etc so I want to reproduce the "cyrus structure" we are using for the last 14 years: - own user folders: INBOX and INBOX.subfolder ... - (if possible: other user folders: user.otheruser...) - converting as much as possible of existing data To get the folders/messages into the new dovecot server(s) I'm thinking about some repeated "doveadm mirror / backup -R ... imapc:" runs while the cyrus server is still in use. The first sync run will take several days but a few more and the time will be short enough to do the complete switch-over w/o surprises. Insertion: I played with 2.1.15 and namespaces but maybe I did not understand this well enough: doveadm backup -R -u userx [w or w/o -m INBOX and/or -n INBOX] imapc: => if cyrus userx has permissions on other users mailboxes these folders are also copied. ... copied _into_ the INBOX of (dovecot) userx. I too got the known problems with INBOX.INBOX. paths. I changed dsync-brain.c sources to skip "^user." folders and to cut the additional "INBOX." => seems okay... messages (only the expected) got transferred! --- To see if things still work as with 2.1.15 (no dsync source modification!) I did (as before with 2.1.15): doveadm backup [-Dv] -R -u cyrtest1(a)iai.uni-bonn.de -m INBOX imapc: => but it crashes (signal 6) doveadm(cyrtest1(a)iai.uni-bonn.de): Debug: auth input:

Hello! I have a nasty problem with a loop when I enable quota_warning. The mailbox fills up with thousands of email within seconds. This happens only with mbox'es retrieved with POP3. From MAILER-DAEMON Thu Mar 21 13:54:07 2013 From: support(a)anup.de Subject: Mailbox Quota-Warnung X-UID: 8036 Status: X-Keywords: Content-Length: 41 Ihre Mailbox ist jetzt zu below% belegt. # doveconf -n # 2.1.7: /usr/etc/dovecot/dovecot.conf auth_mechanisms = plain cram-md5 auth_verbose = yes disable_plaintext_auth = no hostname = delta.bitcorner.eu log_path = /var/log/dovecot1 mail_home = /var/spool/vhosts/%d/%n mail_plugins = quota 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 ihave vacation-seconds namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = Sent quota = maildir:User quota quota_rule = *:storage=500MB quota_rule2 = Trash:storage=+10%% sieve = ~/.dovecot.sieve sieve_dir = ~/.sieve sieve_extensions = +vacation-seconds sieve_vacation_default_period = 10d sieve_vacation_max_period = 30d sieve_vacation_min_period = 1h } postmaster_address = postmaster(a)bitcorner.de protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } service managesieve-login { inet_listener sieve { port = 4190 } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { mode = 0666 user = vmail } user = vmail } ssl_cert = </etc/dovecot/ssl/hostcert.pem ssl_key = </etc/dovecot/ssl/hostkey.pem userdb { args = /etc/dovecot/passwd driver = passwd-file } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = quota quota sieve } protocol imap { imap_idle_notify_interval = 29 mins mail_max_userip_connections = 20 mail_plugins = quota quota imap_quota autocreate } protocol lmtp { mail_plugins = quota sieve } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 } protocol pop3 { mail_max_userip_connections = 10 mail_plugins = quota quota pop3_uidl_format = %08Xu%08Xv } The problem occurs when I add the following to dovecot.conf: quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = -storage=100%% quota-warning below %u # user is no longer over quota The script executed looks like this: #!/bin/sh PERCENT=$1 USER=$2 cat << EOF | /usr/libexec/dovecot/dovecot-lda -d $USER -o "plugin/quota=maildir:User quota:noenforcing" From: support(a)anup.de Subject: Mailbox Quota-Warnung Ihre Mailbox ist jetzt zu $PERCENT% belegt.
