[Dovecot] Maildir or Mdbox and expunge messages.
by Evgeny Basov 20 Mar '13

20 Mar '13

Hello. I tested dovecot's work with expunge messages on Mdbox over strace (see at tail of message). As I can see dovecot process opens old storage m.* file, reads it content, opens new temporary file, writes in this one content and rename this new one to m.(*+1). How fast this algorithm works on system with about 10000 users and 5Tb data? I will use mdbox_rotate_interval for delayed expunge but I think that simple delete file in Maildir must be faster than expunge from Mdbox. Please, tell me about real experience work with Mdbox on big loaded systems. ++++++++++++++++ 0.000017 open("/var/vmail/example.org/user/storage/.temp.1362474108.P7152Q0M909647.mailsys", O_RDWR|O_CREAT|O_TRUNC, 0666) = 11 0.000063 umask(077) = 066 0.000015 fallocate(11, 01, 0, 10485760) = 0 0.000054 fstat(11, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0 0.000043 pread(10, "\1\2N 0000000000000285\nFC"..., 8192, 16) = 1465 0.000025 write(11, "2 M1e C5135b47c\n\1\2N 000"..., 691) = 691 0.000041 stat("/var/vmail/example.org/user/indexes/storage/dovecot.map.index.log.2", 0x7fff235b34c0) = -1 ENOENT (No such file or directory) 0.000026 alarm(180) = 0 0.000018 fcntl(9, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}) = 0 0.000020 alarm(0) = 180 0.000018 stat("/var/vmail/example.org/user/indexes/storage/dovecot.map.index.log", {st_mode=S_IFREG|0600, st_size=3656, ...}) = 0 0.000031 fstat(9, {st_mode=S_IFREG|0600, st_size=3656, ...}) = 0 0.000041 write(11, "\n\1\3\nR5135ad97\nV29b\nG5840870697ad"..., 62) = 62 0.000023 fdatasync(11) = 0 0.079275 stat("/var/vmail/example.org/user/storage/m.8", 0x7fff235b3640) = -1 ENOENT (No such file or directory) 0.000061 rename("/var/vmail/example.org/user/storage/.temp.1362474108.P7152Q0M909647.mailsys", "/var/vmail/example.org/user/storage/m.8") = 0 0.000164 write(9, "\200\200\200\203\0\0\10\20\210\0\0\0\200\200\200\207@\0\0\20\0\0\0\0\0\0\0\0\10\0\0\0"..., 152) = 152 0.000094 fcntl(9, F_SETLK, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}) = 0 0.000042 unlink("/var/vmail/example.org/user/storage/m.7") = 0 0.000059 stat("/var/vmail/example.org/user/indexes/storage/dovecot.map.index.log", {st_mode=S_IFREG|0600, st_size=3808, ...}) = 0 0.000055 fstat(9, {st_mode=S_IFREG|0600, st_size=3808, ...}) = 0

[Dovecot] Stability of extraction of attachment
by Angel L. Mateo 20 Mar '13

20 Mar '13

Hello, We are migrating our dovecot servers from 2.1.9 to 2.1.15 (or 2.2 if there is a stable version soon) and maildir format to mdbox. Looking for mdbox options I have found options: * mail_attachment_dir * mail_attachement_min_size * mail_attachment_fs * mail_attachment_hash but this options are described with the message: # WARNING: This feature hasn't been tested much yet. Use at your own risk. What is the state of these options? Could I use it in a production environment? In case of yes, what is the best deduplicating option? Let it to the FS? Or configuring with "sis posix" or "sis-queue posix"? -- Angel L.

[Dovecot] Exposing masteruser info to cllients via lmtp-proxy connections
by Alexandr Sabitov 20 Mar '13

20 Mar '13

Hello, Please somebody suggest me how to remove the "*masteruser" appendix from the dovecot director database while using masteruser authentication. My situation is: - all users get authenticated in LDAP on the dovecot-director frontend - then they are forwarded to dovecot backend as username*masteruser ( this is a way how to proxy users with encrypted passwords). To enable it a added an extra field in LDAP-dovecot configuration: destuser=%u*masteruser This works OK, but problems are: - I have lmtp-proxy on the dovecot frontend and I have to use the same "%u*masteruser" field in lmtp passdb because the director thinks that me(a)mail.com and me(a)mail.com*masteruser are different users and would send lmtp-proxy connections to other dovecot backend. Here is a problem: "Delivery-To" and "Received" fields in any email contains "*masteruser" ! I need to remove any mentions about "masteruser" authentication from client emails. Also another little problem: - If I run "doveadm status" tool then to get user's data I need to specify user as "username*masteruser" Thank you in advance. Alexandr Sabitov Netregistry

[Dovecot] v2.2 status update
by Timo Sirainen 20 Mar '13

20 Mar '13

So, I'm still planning on getting v2.2.0 out Really Soon now. Unfortunately I've had to quickly develop some rather large features still at this stage. I was initially planning on leaving them for v2.3, but they were a requirement for one project and implementing them now to v2.2 was the least amount of trouble for me. (And yes, I'm aware I haven't replied to a lot of emails in this list. There are about 60 unread ones. Hopefully I'll have time to go through them this week.) So, what we have now: * dsync can sync ACLs * dsync can sync Sieve scripts - Slightly unfinished patch for Pigeonhole at http://dovecot.org/patches/2.2/doveadm-sieve-plugin.diff * dsync does the ACL/Sieve syncing by having implemented generic mailbox attribute syncing. (The ACLs/Sieve scripts are transparently mapped into the attribute hierarchy.) ACL plugin also supports now restricting attribute set/get/iteration. IMAP METADATA extension can be implemented using mailbox attributes. The dsync/ACL support was the main reason why I had planned on delaying native IMAP METADATA support until v2.3, but there's really no reason for that anymore. So expect IMAP METADATA support also early in v2.2.x (disabled by default). I'll still need to figure out how to do quota for it. * LDAP values can now have DN pointers to other entries that are queried. (Support for LDAP URLs could probably also be added with little trouble.) The configuration becomes a bit more complex again, but until the whole LDAP configuration is redesigned this will work. Example: user_attrs = \ =user=%{ldap:uid}, \ @mail=%{ldap:mailDN}, \ =uid=%{ldap:uidNumber@mail}, \ =gid=%{ldap:gidNumber@mail}, \ =home=%{ldap:rootPath@mail}/%d/%n

Dear sir, I have to set up a mail gateway which will be explored to Internet and a secure mail server in the Intranet. I need a smart imap proxy in the mail gateway which will fetch the mail from server and present to user through either a stand alone mail client or a web mail client. All authentication is through ldap server. I have installed Dovecot 2.2 Unstable in my Ubuntu 12.04 with ssl enabled But when I am starting dovecot, I am getting the following error *doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-ssl.conf line 12: Unknown setting: ssl_cert* I couldn't figure out what is wrong. Please help me to sort it out.

Did you verified that the header "To" really exists in the message and that "info(a)info.xx.com" is part of it? The log you've posted displays the envelope information, which is not necessary the same as the header information. Also, remove the precompiled Sieve script, in order to ensure that the pre-compiled one is really one from the script. You could also decompile it to make sure, it has been created from your test script. You'll find sieve-dump in src/sieve-tools/, if you compile from sources, or maybe in /usr/local/bin.

[Dovecot] SMTP Client authentication to remote Postfix/Dovecot
by Christian Benke 19 Mar '13

19 Mar '13

Hello! This is probably another basic question and i'm not even sure if it's something where Dovecot is involved, but i'll give it a shot. So i've setup Postfix with Dovecot and system-auth on my remote server. So far it looks like everything is working fine and dandy via SASL(PLAIN) and TLS. I'm just not happy about my local SMTP client settings. I'm going to try to work with mutt in the future, so i need a local MTA - i've decided to try it with Postfix. This works so far and i can send mails with mutt. However - my setup relies on smtp_sasl_password_maps for authentication. I'm not too happy to have plaintext-passwords of remote systems lying around on my local filesystem. It doesn't really ease my mind that the file is readable by root only, this doesn't help if my laptop's harddisk gets mounted elsewhere. Are there alternatives or better ways to do SMTP authentication? http://www.postfix.org/SASL_README.html#server_cyrus_comm says: > saslauthd can verify the SMTP client credentials by using them to log into an IMAP server So i have my mutt-client which is logged in to the remote Dovecot IMAP. Mutt uses the local MTA to send the mail. Is there some way to tell the local postfix or a local dovecot to authenticate the SMTP-Session via the existing IMAP-login? Or some other way where i at least don't rely on plaintext passwords but secure, encrypted hashes? Sorry if this is a redundant thread, "smtp client" authentication site:dovecot.org/list' and the likes are not exactly the most rewarding or unique search terms unfortunately. Thanks, Christian -- Central Asia by bike, starting May 2013 - http://poab.org

[Dovecot] Integrating with Drupal SQL db

Hi I'm trying to get Dovecot to use Drupal users password for authenticating IMAP users. But I just cant figure out how to make Dovecot understand the password hash type that Drupal 7 is using. My example user with password Teacher1 looks like this in Drupal database: $S$DZwJa.U8HXT2PvTmwCK13rGEYEvnx5DB6/hlqnfCBum4s4U7MVWU Dovecot retrieves this hash but complains that its not a recognized hash type, or that the hash is wrong, depending on if I change the default hash type in Dovecot config.
