[Dovecot] dovecot-1.2.9: OK No messages copied
by Attila Sipos 26 Mar '12

26 Mar '12

Hi, When I issue an IMAP copy command using the wrong UID, the server gives an "OK No messages copied" response. This seems like the wrong response to me. If the UID doesn't exist, then it should respond with a "No" response - maybe something like "NO - copy error: bad UID" I believe "OK No messages copied" would only be a suitable response if the email with the supplied UID had already been known to be copied successfully. I am using dovecot 1.2.9 - has this been fixed in newer versions of dovecot? Regards Attila Attila Sipos Netcall Telecom Ltd Registered in England 2831215.

[Dovecot] Many messages clustered around the same date.saved value
by Joseph Tam 26 Mar '12

26 Mar '12

Subject: Different user messages clustered around the same date.saved value After updating dovecot to 2.1.3, I can now use "doveadm expunge -A ..." to iterate through all user trash folders and expunge old messages. However, I noticed a strange thing: querying what would have been deleted doveadm -ftab fetch -A "date.saved" mailbox Trash savedbefore 7d showed many date.saved values are clustered around the same timestamp, even among different user's Trash mailbox. One user's trash mailbox having the same date.saved is explained by a user deleting a lot of message at one time, but I can't explain why many different users would have messages with the same (or closeby) date.saved value. For example, the output of the above query on my system showed the 10s window /2012-03-05 18:08:0[0-9]/ matched 7658 messages among 22 different user Trash mailboxes, which is statistically unlikely. I did't see anything special in the dovecot logs at this time to explain this. What would cause this? Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] migrating mailboxes on dovecot
by Spyros Tsiolis 25 Mar '12

25 Mar '12

Hello all, I want to ask about something I never did before. I have a dovecot/XMail/LAMP/Horde installation on a CentOS 5.5 32-bit system with two domains : domainA and domainB All the users used to have their mailboxes on domainA. However the personell dept decided that 90% of the users will have to have their mailboxes set to domainB and the other 10% will stay at domainA. So, I need to migrate those mailboxes from domainA to domainB. The only thing is I haven't done that ever. The directory structure is : "/var/MailRoot/domains/domainX/Username/Maildir/" and under there the usual suspects : cur (directory) dovecot.index.cache (file) dovecot-keywords (file) dovecot-uidvalidity (file) new (directory) tmp (directory) dovecot.index (file) dovecot.index.log (file) dovecot-uidlist (file) dovecot-uidvalidity.4cc055c6 (file) subscriptions (file) Using dovecot v1.2.15 Any help would be appreciated. Iam supposed to do this today !! :-) Thank you all, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] sysconfdir depreacted
by Noel Butler 25 Mar '12

25 Mar '12

The purpose of any build scripts --sysconfdir is to tell the configuration to build in a path for its binaries configuration file(s). Dovecot 2.1.3, seems to insist that that directory is now /etc/dovecot/ ignoring --sysconfdir=/etc as in 1.2.x and previous majors before that, is this a bug? if not, then I see no point of sysconfdir any more and it should be removed, if dovecot deliberately ignores what it is told to use.

[Dovecot] dovecot and cloudfile systems
by jackie sparks 24 Mar '12

24 Mar '12

I'm trying to store mailboxes in a cloudfile system and I am running into alot of problems using courier, between time skew, file locking and cache creation problems. I was wondering if dovecot has any problems using maildirs across a limited fuse file system. I cant lock files, This is accessed using the fuse library. I thought taking out the standard checking for return values would be a work around because everything imap daemon is doing can be done from a shell by hand except filelocking and setting times on files. I am doing this on Rack Spaces cloud files. This is something that not many if any are doing. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-= This e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C.

Re: [Dovecot] kernel problem in RedHat? -- RH specific, or what linux kernels does this affect?
by Linda Walsh 24 Mar '12

24 Mar '12

Is this redhat's version of the kernel only? Or does it apply to other linux kernels and other distros? Any idea what linux kernel versions might cause this? (from main dovecot webpage news) Thu Mar 22 14:38:53 EET 2012 Red Hat/CentOS users: A recent kernel update <https://bugzilla.redhat.com/show_bug.cgi?id=681578> causes Dovecot to start failing after it has reached 1000 child processes. To fix this, downgrade your kernel until Red Hat releases a fixed kernel.

[Dovecot] Problems with upgrade 2.0.16 -> 2.1.3
by Joseph Tam 24 Mar '12

24 Mar '12

I ran into two issues trying to upgrade our dovecot installation (Solaris 10). 1) Does not compile with OpenSSL 0.9.7 Not a big deal, as I was able to successfully against OpenSSL 0.9.8, but does dovecot require OpenSSL >= 0.9.8 now? libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-test -std=gnu99 -O3 -fomit-frame-pointer -mcpu=ultrasparc -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -MT istream-openssl.lo -MD -MP -MF .deps/istream-openssl.Tpo -c istream-openssl.c -fPIC -DPIC -o .libs/istream-openssl.o iostream-openssl-context.c:9:28: openssl/engine.h: No such file or directory iostream-openssl-context.c: In function `ssl_iostream_deinit_global': iostream-openssl-context.c:431: warning: implicit declaration of function `ENGINE_finish' iostream-openssl-context.c:432: warning: implicit declaration of function `ENGINE_cleanup' ... 2) Dovecot's LDA does not work After stopping the the old dovecot, and starting dovecot 2.1.3 using tghe exact same config file, local mail delivery tempfails: Mar 23 02:51:51 server dovecot: auth: Error: getpeerucred() failed: Bad address Mar 23 02:51:51 server dovecot: auth: Error: userdb connection: Failed to get peer's credentials Mar 23 02:51:51 server dovecot: lda: Error: userdb lookup(j.tam): Disconnected unexpectedly Mar 23 02:51:51 server dovecot: lda: Fatal: Internal error occurred.
