FYI: dovecot (008632bdfd2c) compilation woes, and minor glitch regarding update-version.sh
by Michael Grimm 10 May '15

10 May '15

Hi — 1) I'm trying to compile a recent hg dovecot version (008632bdfd2c) at a FBSD10-STABLE system without success: libtool: compile: cc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-test -I/usr/local/include -DUDHRDIR=\"../../src/lib-fts\" -DDATADIR=\"/usr/local/share/dovecot\" -DTEST_STOPWORDS_DIR=\"../../src/lib-fts\" -I/usr/local/include -std=gnu99 -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wno-duplicate-decl-specifier -Wstrict-aliasing=2 -I/usr/local/include -MT fts-tokenizer-generic.lo -MD -MP -MF .deps/fts-tokenizer-generic.Tpo -c fts-tokenizer-generic.c -fPIC -DPIC -o .libs/fts-tokenizer-generic.o fts-tokenizer-generic.c:111:18: error: use of undeclared identifier 'White_Space' if (uint32_find(White_Space, N_ELEMENTS(White_Space), c, &idx)) ^ fts-tokenizer-generic.c:113:18: error: use of undeclared identifier 'Dash' if (uint32_find(Dash, N_ELEMENTS(Dash), c, &idx)) ^ […] fts-tokenizer-generic.c:212:18: error: use of undeclared identifier 'MidLetter' if (uint32_find(MidLetter, N_ELEMENTS(MidLetter), c, &idx)) ^ fts-tokenizer-generic.c:214:18: error: use of undeclared identifier 'MidNum' if (uint32_find(MidNum, N_ELEMENTS(MidNum), c, &idx)) ^ fatal error: too many errors emitted, stopping now [-ferror-limit=] 20 errors generated.

Thus, update-version.sh will fail to evaluate hg's changeset. As a quick fix I needed to create a link: python -> python2 Regards, Michael

Full text search indexes not used for header/body OR queries?
by Robert L Mathews 09 May '15

09 May '15

I've noticed that when using Lucene full text search, most queries use the indexes and/or header cache and are fast: . SEARCH BODY test . OK Search completed (0.001 secs). . SEARCH SUBJECT test . OK Search completed (0.053 secs). . SEARCH BODY test SUBJECT test . OK Search completed (0.002 secs). . SEARCH OR SUBJECT test FROM test . OK Search completed (0.093 secs). But an OR query that mixes headers and body does not use the available FTS indexes for the BODY part and is slow: . SEARCH OR BODY test SUBJECT test * OK Searched 62% of the mailbox, ETA 0:05 * OK Searched 70% of the mailbox, ETA 0:04 . OK Search completed (15.147 secs). Is this the expected behavior? Since the FTS code can handle an AND of header and body searches, I'm surprised it doesn't do the same for an OR. I noticed this while tracking down poor performance in Thunderbird, which issues searches like this: UID SEARCH RETURN (ALL) (OR FROM "Evelyn" (OR SUBJECT "Evelyn" (OR TO "Evelyn" (OR CC "Evelyn" BODY "Evelyn")))) NOT DELETED These are slow even with FTS enabled because of this behavior. I'm using Dovecot 2.1.7 from Debian wheezy. (I know this is outdated; however, I've examined the 2.1.x and 2.2.x changelogs and found no mention of it.) -- Robert L Mathews, Tiger Technologies, http://www.tigertech.net/

PublicFolders using Maildir and INDEXPVT in Dovecot v2.2.13
by Panayiotis Fafakos 08 May '15

08 May '15

Dear all, we have succesfully configured Dovecot v2.2.13 in debian wheezy 7.8 (using backports) using Maildir structure, to use private index files for the \Seen flag on a per user basis. All users access their emails and Public Folders using IMAP protocol. The problem is that when a user moves an email from publicFolderA to publicFolderB under the same namespace the other users see this message as unread, although they have actually read it when it was in publicFolderA. Please note that this is an old message which has been moved , it was not copied, so the actual UID should be the same... Is there a way to keep the \Seen flag for the messages that are moved from folder to folder? Is there a way to keep the \Seen flag in a database, so that we can ignore the folder structure and only check the message UIDs? We could use MySQL, PgSQL or even SQLite... Below follows the Public-Folder namespace declaration: ------------------------------------------ namespace { inbox = no location = maildir:/var/vmail/Public-Folders:LAYOUT=fs:INDEXPVT=~/Maildir/public/%u prefix = Public-Folders/ separator = / subscriptions = no type = public } ------------------------------------------ With the above system configuration we have the complete folder structure under ~/Maildir/public/%u, and many log files, one for each folder a user has accessed. Could we only have one index file for each user for all the public folder structure under the same namespace? Kind regards to all, Panayiotis Fafakos

Different mdbox_rotate_size for primary and alternate storage
by Paolo Cravero 08 May '15

08 May '15

Hello. In order to speed up backups of very very old messages I would like to set two different limits for mdbox_rotate_size. Like, 50M for primary storage and 100M or larger for alternate storage. There is no mention in docs or such a possibility, so I assume it is not possible. Is that correct? While I am at it, is it possible to configure primary storage as maildir (sturdy indexes) and altstorage as mdbox (more delicate indexes)? Thanks, Paolo

Dovecot and data migration
by Alain BERNARD 07 May '15

07 May '15

Hi, Our legacy data store retains a single copy of a message regardless of the number of mailboxes in which that message resides. It does this by creating hard links to that message in the mailboxes containing that message. Thus, when we perform data migration to the server target (Dovecot), the copies of the same message are copied over with the migration process (imapsync). We use the storage format maildir. With a small message store, this means that a lot of messages are duplicated unnecessarily. How to reduce message store size due to duplicate storage of identical messages ? Does a relinking function exist and can be run in real-time mode ? how can we configure Dovecot to deduplicate for all users using a hash to determine whether the file could be already exist ? Thanks in advance. Memo

Mapping other Inbox method (symlink vs ACL)
by Kevin Laurie 07 May '15

07 May '15

Hi, I am trying to map a account(bob(a)mydomain.com) to help(a)mydomain.com. I would like him to see/access Inbox,Sent,Junk,Trash of help(a)mydomain.com . What would you reckon would be the best way to do this? ACL or Symlink? With symlink, I dont think I will be able to set permissions. Is it possible to use ACL to get the entire email account access(the inbox, junk, sent etc.)?

lmpt director and ldap userdb
by Angel L. Mateo 06 May '15

06 May '15

Hello, I've been using dovecot for a long time, but now I'm having troubles with I change I need to make. I have a director server in front of two backend servers. All of these servers are running dovecot 2.1.16. Redirection to backend servers are based in an attribute of a ldap server. My users are defined in this same ldap server. At this moment, for user authentication we use password lookups. My current configuration at both frontend and backend servers is attached. But now I need to change it to bind authentication, so the only change I've made is changing "auth_bind=no" to "auth_bind=yes". After this change, backend servers are working fine. Director servers are also working for POP and IMAP connections, but for LMTP they are returning: May 6 10:23:35 myotis40 dovecot: lmtp(48026): Error: user myuser(a)um.es: Auth PASS lookup failed This error is returned without any ldap lookup, neither connection to backend servers. Any help? thanks in advance. -- Angel L.
