[Dovecot] dovecot from debian lenny-backports does not accept connections
by Joelly Alexander 15 May '10

15 May '10

hi, dovecot from the debian lenny backports does not successfully accept incomming imap or imaps connections; when the client connect i can see the clients ip address in an imap-process but the client cannot succesfully connect and retries this several times where an new imap-process is bound until the maximum connections per client is reached; when the client is closed the imap-processes on the server stay opened, even when dovecot will be restarted or stopped - the processes needs to killed manually; --- snip --- 2010-05-14 02:24:42 auth(default): Info: client in: AUTH 1 PLAIN service=imap

[Dovecot] Wiki page(s) to document executable tools?
by William Blunn 14 May '10

14 May '10

Motivated by a desire to know what "doveadm" does: Do we want to be having a page or pages in the Dovecot Wiki which document the executable tools? It might be an idea for each one to say: * What the tool does * How it normally gets invoked (e.g. manually by the administrator, automatically by some other part of Dovecot, automatically by something else) * What parameters it could take and what they would do List of executable tools: (found in Debian dovecot 1.0.15) lib/dovecot/ checkpassword-reply deliver dict dovecot-auth dovecot-config gdbhelper idxview imap imap-login logview managesieve managesieve-login modules pop3 pop3-login rawlog sievec sieved ssl-build-param (found in dovecot 2.0beta5) bin/ doveadm doveconf dsync libexec/dovecot/ anvil auth config dns-client dovecot-lda expire-tool imap-utf7 listview lmtp log maildirlock script ssl-params Regards, Bill

I can also see Dovecot 2.0 builds in there. But they appear to be being made every couple hours, so presumably based on the bleeding edge of the Mercurial repository. It would be kind of handy to have a Debian package of the original 2.0 beta 5 build. Is that lying around anywhere? Regards, Bill

[Dovecot] dovecot 2.0 vs. SELinux
by Michal Hlavinka 14 May '10

14 May '10

Hi, we were modifying old SELinux rules for dovecot 2.0. Everything seems ok, only one report seems odd: "SELinux is preventing /usr/sbin/dovecot "write" access on dovecot.conf." Looking at strace output, dovecot tries to use socket on /etc/dovecot/dovecot.conf which is regular file and no socket: ... geteuid() = 0 getegid() = 0 open("/dev/null", O_WRONLY) = 3 fcntl(3, F_GETFD) = 0 fcntl(3, F_SETFD, FD_CLOEXEC) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/var/run/dovecot/config"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 70000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 90000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 80000000}, NULL) = 0 ... (tries to connect 14x) traceback for connect causing this selinux denial is: connect net_connect_unix : lib/network.c #246 net_connect_unix_with_retries : lib/network.c : #255 master_service_open_config : lib-master/master-service-settings.c #157 master_service_settings_read : lib-master/master-service-settings.c #302 master_settings_read : master/main.c main : master/main.c Does anyone know what happens here? Why dovecot tries to use regular file dovecot.conf as socket? There is probably some magic in it (from my pov) which I don't understand. Regards, Michal Hlavinka

Is there a tool to recover space used by refcount=0 messages in mdbox storage files? The wiki talks about it but it isn't clear where the tool is. Regards, Bill

hi, I am currently experiencing a problem: there is a group of 200 people to this group when a user send a large message (50MB), can easily lead to congestion. Is there a good way to handle such a situation, like the hard link cyrus?

[Dovecot] Compressed mail archives
by Will Palmer 14 May '10

14 May '10

Hello, I have recently begun using IMAP to access my mails, and have found that the size of my maildir is quickly getting larger than I had anticipated. Googling around, I've seen a lot of messages related to compressing individual messages in a maildir. However, what I'm really looking for is a solution which will allow multiple messages to be compressed into a single compressed file, while still allowing those messages to be accessed via IMAP. The reasoning behind this is that most of my incoming mail consists of many very-similar messages (for example, it is not unheard of for me to receive 10,000 emails detailing the same error report over a weekend, with the actual "needs to be processed" parts stuck on the end of each message) I'm expecting a simple "no, there's no way to do that", but I wouldn't mind being pleasantly surprised. My question again: Is there any way to keep a bundle of older mails compressed, so that they can enjoy the high compression of being very similar to each-other, while still allowing access via imap? A solution may involve (just throwing out ideas here, which I have no idea how to implement) putting messages older than N days into an MBox file, and either somehow linking my account to that file (so that my account consists of [compressed readonly Mbox]+[live uncompressed Maildir]), or perhaps the first half of that, but accessing archived messages through a separate account. (Not the preferred way, but if it's the only way, I'll do it) But really I don't even know if it's possible to have dovecot support MBox and Maildir simultaneously, nor do I know enough about the MBox format to even know if the IMAP-style "multiple mailboxes" thing is possible in MBox. Please excuse my no-doubt confused terminology and general air of doesn't-know-what-he's-talking-about. The internals of e-mail are generally not my thing, so I'd appreciate any pointing in the right direction which anyone may have to offer. Any ideas?
