[Dovecot] fts size
by Jan-Frode Myklebust 02 Mar '12

02 Mar '12

Does anybody have any numbers for how large storage one will need for the fts indexing server? I see the wiki says 30% of mailbox size for Squat (partial=4 full=4). Is it similar for lucene/solr? Do I understand correctly if I think http://wiki2.dovecot.org/Plugins/FTS/Lucene will create an index for each user in his home directory? Will this be accounted for in the users' quota? -jf

[Dovecot] 2.1.1: subscriptions: Removing invalid entry
by Ralf Hildebrandt 01 Mar '12

01 Mar '12

Admittedly, it's not a valid folder name and dovecot is right in removing it: Feb 28 17:50:05 postamt dovecot: imap(kbaessle): Warning: Subscriptions file /home/k/b/kbaessle/Maildir/subscriptions: Removing invalid entry: Entw�rfe ...but when looking at the subscription file AFTER the removal, that file contained an empty line. I don't think that's correct. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] dovecot-2.1-pigeonhole-0.3.0 identifier redeclared: sieve_multiscript_run (patch)
by Piotr Tarnowski 29 Feb '12

29 Feb '12

Hi, I recently compiled dovecot-2.1.1 on Solaris 10 with Sun Studio, but when I want to compile Sieve for this version (dovecot-2.1-pigeonhole-0.3.0) I get an error: "sieve.c", line 578: identifier redeclared: sieve_multiscript_run and I see that declaration in sieve.h is different from definition in sieve.c, so compilation process fails with SunStudio cc compiler. I have done a quick hack to correct this, and then compiled successfully. Patch is included as attachment. Full output, OS and compiler versions below: libtool: compile: cc -DHAVE_CONFIG_H -I. -I../.. -I/home/soft/dovecot/dovecot-2.1.1 -I/home/soft/dovecot/dovecot-2.1.1/src/lib -I/home/soft/dovecot/dovecot-2.1.1/src/lib-dict -I/home/soft/dovecot/dovecot-2.1.1/src/lib-dns -I/home/soft/dovecot/dovecot-2.1.1/src/lib-mail -I/home/soft/dovecot/dovecot-2.1.1/src/lib-imap -I/home/soft/dovecot/dovecot-2.1.1/src/lib-fs -I/home/soft/dovecot/dovecot-2.1.1/src/lib-charset -I/home/soft/dovecot/dovecot-2.1.1/src/lib-index -I/home/soft/dovecot/dovecot-2.1.1/src/lib-storage -I/home/soft/dovecot/dovecot-2.1.1/src/lib-storage/index -I/home/soft/dovecot/dovecot-2.1.1/src/lib-storage/index/raw -I/home/soft/dovecot/dovecot-2.1.1/src/lib-lda -I/home/soft/dovecot/dovecot-2.1.1/src/lda -I/home/soft/dovecot/dovecot-2.1.1/src/lib-master -I/home/soft/dovecot/dovecot-2.1.1/src/lib-settings -DMODULEDIR=\"/usr/local/dovecot-2.1.1/lib/dovecot\" -I/usr/local/openldap/include -I/usr/local/ssl/include -I/usr/local/include -xO3 -xautopar -c sieve.c -KPIC -DPIC -o .libs/sieve.o "sieve-common.h", line 33: warning: useless declaration "/home/soft/dovecot/dovecot-2.1.1/src/lib-storage/mailbox-list.h", line 13: warning: useless declaration "sieve.c", line 578: identifier redeclared: sieve_multiscript_run current : function(pointer to struct sieve_multiscript {pointer to struct sieve_instance {..} svinst, pointer to struct sieve_result {..} result, pointer to const struct sieve_message_data {..} msgdata, pointer to const struct sieve_script_env {..} scriptenv, int status, _Bool active, _Bool keep, pointer to struct ostream {..} teststream}, pointer to struct sieve_binary {}, pointer to struct sieve_error_handler {pointer to struct pool {..} pool, int refcount, pointer to struct sieve_instance {..} svinst, pointer to struct sieve_error_handler {..} parent, unsigned int max_errors, unsigned int errors, unsigned int warnings, _Bool log_info, _Bool log_debug, pointer to function(..) returning void verror, pointer to function(..) returning void vwarning, pointer to function(..) returning void vinfo, pointer to function(..) returning void vdebug, pointer to function(..) returning void free}, unsigned int, _Bool) returning _Bool previous: function(pointer to struct sieve_multiscript {pointer to struct sieve_instance {..} svinst, pointer to struct sieve_result {..} result, pointer to const struct sieve_message_data {..} msgdata, pointer to const struct sieve_script_env {..} scriptenv, int status, _Bool active, _Bool keep, pointer to struct ostream {..} teststream}, pointer to struct sieve_binary {}, pointer to struct sieve_error_handler {pointer to struct pool {..} pool, int refcount, pointer to struct sieve_instance {..} svinst, pointer to struct sieve_error_handler {..} parent, unsigned int max_errors, unsigned int errors, unsigned int warnings, _Bool log_info, _Bool log_debug, pointer to function(..) returning void verror, pointer to function(..) returning void vwarning, pointer to function(..) returning void vinfo, pointer to function(..) returning void vdebug, pointer to function(..) returning void free}, enum sieve_runtime_flags {SIEVE_RUNTIME_FLAG_NOGLOBAL(1)}, _Bool) returning _Bool : "sieve.h", line 168 cc: acomp failed for sieve.c *** Error code 1 dmake: Fatal error: Command failed for target `sieve.lo' Current working directory /home/soft/dovecot/dovecot-2.1-pigeonhole-0.3.0/src/lib-sieve *** Error code 1 The following command caused the error: fail= failcom='exit 1'; \ for f in x $MAKEFLAGS; do \ case $f in \ *=* | --[!k]*);; \ *k*) failcom='fail=yes';; \ esac; \ done; \ dot_seen=no; \ target=`echo all-recursive | sed s/-recursive//`; \ list='plugins'; for subdir in $list; do \ echo "Making $target in $subdir"; \ if test "$subdir" = "."; then \ dot_seen=yes; \ local_target="$target-am"; \ else \ local_target="$target"; \ fi; \ (cd $subdir && dmake $local_target) \ || eval $failcom; \ done; \ if test "$dot_seen" = "no"; then \ dmake "$target-am" || exit 1; \ fi; test -z "$fail" dmake: Fatal error: Command failed for target `all-recursive' % uname -a SunOS soft 5.10 Generic_142909-17 sun4u sparc SUNW,Sun-Fire-V890 Solaris % version Machine hardware: sun4u OS version: 5.10 Processor type: sparc Hardware: SUNW,Sun-Fire-V890 The following components are installed on your system: Sun Studio 12 update 1 Sun Studio 12 update 1 C Compiler Sun Studio 12 update 1 C++ Compiler Sun Studio 12 update 1 Tools.h++ 7.1 Sun Studio 12 update 1 C++ Standard 64-bit Class Library Sun Studio 12 update 1 Garbage Collector Sun Studio 12 update 1 Fortran 95 Sun Studio 12 update 1 Debugging Tools (including dbx) Sun Studio 12 update 1 IDE Sun Studio 12 update 1 Performance Analyzer (including collect, ...)

[Dovecot] What's behind the message ...
by Frank Elsner 29 Feb '12

29 Feb '12

... Warning: /media/Backup28a is no longer mounted. If this is intentional, remove it with doveadm mount Hello, the above message appeared when I restarted dovecot. What has dovecot to deal with my USB-Backup-Disk? Dovecot cares about filesystem without any relation to the mail system? Why this? What's bedind? Thanks in advance, Frank Elsner

[Dovecot] per-user limit?
by Peter Hessler 29 Feb '12

29 Feb '12

I am seeing a problem where users are limited to 6 imap logins total. One of my users has a bunch of phones and computers, and wants them all on at the same time. I'm looking through my configuration, and I cannot see a limit on how many times a single user can connect. He is connecting from different IPs. Any ideas? My logs show the following error when they attempt to auth for a 7th time: dovecot: imap-login: Disconnected (no auth attempts): rip=111.yy.zz.xx, lip=81.209.183.113, TLS $ dovecot -n # 2.0.16: /etc/dovecot/dovecot.conf # OS: OpenBSD 5.1 amd64 ffs auth_mechanisms = plain login base_dir = /var/dovecot/ listen = *, [::] mail_location = maildir:/usr/home/%u/Maildir 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 mbox_write_locks = fcntl passdb { driver = bsdauth } service auth { unix_listener /var/run/dovecot/auth-master { mode = 0600 } unix_listener /var/spool/postfix/private/auth { group = wheel mode = 0660 user = _postfix } user = root } service imap-login { process_limit = 128 process_min_avail = 6 service_count = 1 user = _dovecot } service pop3-login { process_limit = 64 process_min_avail = 6 service_count = 1 user = _dovecot } ssl_cert = </etc/ssl/dovecotcert.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve postmaster_address = postmaster(a)theapt.org } -- We are all in the gutter, but some of us are looking at the stars. -- Oscar Wilde

[Dovecot] Post-login scripting - Trash cleanup
by list＠airstreamcomm.net 29 Feb '12

29 Feb '12

We are considering using the post-login scripting to clear trash older than 90 days from user accounts. has anyone done this, and if so did this cause logins to slow down too much waiting for the trash to purge? One idea was to execute the trash purge script once a day by tracking their logins and seeing that it has already ran that day. Another idea was to call the trash purge script in the background and continue without acknowledging that it has finished to keep logins speedy.

[Dovecot] Master user

Hi, I'd like to have a master user that can read the other users mailboxes. I have only one user who read and write the mail (i.e. I use the static userdb) and I use namespace for public and shared mailboxes. I can authenticate to the server but I am not able to list the mailboxes: > emiliano@dovecot:~$ telnet localhost imap > Trying 127.0.0.1... > Connected to localhost. > Escape character is '^]'. > * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. > 1 login user*master password > 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in > 5 LIST "" * > * LIST (\Unmarked) "."

[Dovecot] Question: Is Server Side Search announced somehow via the IMAP CAPABILITY string?

28 Feb '12

Hey Timo, Subject says it all... This question is a result of an ongoing discussion on the mozilla enterprise list... Is there a standard/reliable way for an IMAP client to determine that an IMAP server supports server side search (with indexes)? Thanks, -- Best regards, Charles
